Background technology
Generally, in mobile radio communications system, in order to call out travelling carriage (incoming call), the channel of (the letter) usefulness of having prepared to collect mail.
PHS (Personal Hand phone System: personal handyphone system) be the mobile radio communications system that has used the TDMA/TDD mode.In PHS, 1 long frame of 5ms is divided into each 4 time slot of upstream and downstream.In each 4 time slot of upstream and downstream, the time slot that is used in the transmitting-receiving of control signal is upstream and downstream 1 time slot separately.The time slot that control information sends usefulness consists of superframe, and the cycle is 1.2 seconds.So-called superframe refers to specify minimum period of descending logical control channel (LCCH:Logical Control Channel) of the time slot position of all LCCH unit.
Notification channel), corresponding to the PCH of all collecting mail (letter) group (Paging Channel (PCH): calling channel) simultaneously and the fixing SCCH that inserts (Signaling Control Channel (signal controlling channel): indivedual unit channel) and USCCH (User Specific Control Channel (the proprietary control channel of user)) descending LCCH unit refers to the BCCH that uses in this system (Broadcasting ControlChannel (BCCH):.Must send BCCH (A) in the beginning time slot of LCCH superframe.But if need, other LCCH unit can temporarily stop and sending other LCCH unit.With in the descending time slot, hold logical control channel LCCH (spacing value of n:LCCH) with the cycle of 5 * n (ms) in control.For example, among the PHS, with under the standard, the spacing value n of LCCH is 20 the public, so the base station sends various control informations with the 100ms interval.In addition, in each collects mail (letter) group, with the interval transmission incoming information of 1 superframe (1.2 seconds).
Even do not having in the situation of incoming information, the base station sends idle PCH.In incoming call message, preserve the information of (letter) travelling carriage number of collecting mail etc. with the structure of 62 bits.
USCCH is the UPCH that can define with physical slot by time in control (User PacketChannel, that is, UPCH user packer channel).Here, UPCH is the two-way channel of point-to-multipoint, carries out the transmission of user data package data.In PHS, if USCCH satisfies gainer, then can select arbitrarily its using method.In addition, USCCH has USCCH (1) and USCCH (2).Here, USCCH (1) covers and reaches identifier (the other symbol of Knowledge), arrives specific terminal (letter).On the other hand, USCCH (2) does not cover and reaches identifier (the other symbol of Knowledge).
With reference to Fig. 1 explanation system from Distribution Center to the PS distributing information in PHS.Here, Fig. 1 is the block diagram of the distribution of information of explanation PHS.Cell Station) 30, PS (travelling carriage: Personal Station) 70 in Fig. 1, the information distribution system 100 of PHS comprises Distribution Center 10, switch 20 (hereinafter referred to as EX), CS (base station:.In existing ways of distribution, calling area when Distribution Center determines the distribution destination, per 1 PS to location register to this while calling area sends information.According to Fig. 1 explanation, at certain while calling area 80 totally 4 of CS30-1, CS30-2, CS30-3, CS30-4 are arranged.And, be registered with 8 PS70 at this while calling area 80.When Distribution Center 10 specified to while during calling area 80 distributing information, the PS70 to this while calling area 80 calls out by platform for location register.Therefore, the EX20 of Distribution Center's 10 pairs of whiles calling area 80 sends information, and all CS from EX20 to while calling area 80 are that CS30-1, CS30-2, CS30-3, CS30-4 send the calling and setting message that is equipped with distributing information.When each CS receives this calling and setting message from EX20, to waiting for that the PS70 that is connected with self sends PCH.
As described above, existing dissemination system is the at the same time interior distribution of calling area unit.Therefore, can not be to the area distribution that is defined as department store etc.In addition, CS is because only send the PCH of the number of PS, and owing to the inadequate resource of the PCH that limits, the common collection of letters (letter) is failed sometimes.
With reference to Fig. 2 explanation order from Distribution Center to the PS distributing information in existing dissemination system.Here, Fig. 2 is the precedence diagram of the distribution of information between explanation Distribution Center, switch, CS, the PS.
In Fig. 2, Distribution Center 10 sends information (T201) to the EX20 of distribution named place of destination while calling area.When EX20 received information, the CS30 of calling area (for the ease of diagram, only putting down in writing CS30-1, CS30-2) sent the calling and setting message (T202, T204) that is equipped with distributing information to being configured in simultaneously.When CS30-1 and CS30-2 receive calling and setting message from EX20, to waiting for that the PS (only putting down in writing PS70-1, PS70-3) that is connected with self sends (and exhale) (PCH) (T203, the T206) that send a telegram here.(letter) number situation consistent with the number of self that receive of the PCH that the PS70-3 affirmation receives, and to CS30-2 transmission LCH foundation request (T207), carry out for connecting TCH (talk channel: the transmitting-receiving of message Traffic CHanel).CS30-2 carries distributing information and sends to PS70-3 (T208) in calling and setting message (LCH distribution).
Between CS30-2 and PS70-3, when PS70-3 failed to receive information for a certain reason, the information that sometimes again sends was also in the failed situation, and PS70-3 loses this distributing information.In addition, because distribution of information is used TCH, so PS70-3 can not carry out common transmission because of the reason of TCH deficiency etc. sometimes.And then, owing between PS70-3 and CS30-2, carry out the information receiving and transmitting that is connected for TCH, can consume the battery of PS70-3.Moreover T209~T224 is the order of common incoming call the (and exhale) response, authentication, call connection, cutting off calling, so description thereof is omitted.
More than, carry out the explanation of PHS, but also can be used for the system with (and the exhale) function of collecting mail of other mobile radio system.UMB (Ultra Mobile Broadband, namely, Ultra-Mobile Broadband) be to have used OFDMA/FDD (Orthogonal Frequency Division MultiplexingAccess/Frequency Division Duplex, that is mobile radio communications system, OFDM access/Frequency Division Duplexing (FDD)).In UMB, also there is the message of calling out for collect mail (letter), when not collecting mail (letter), send idle (the letter) message of collecting mail.In UMB, said PCH is QPCH (Quick Page Channel, that is, quick paging channel) among the PHS.In addition, TCH is called DCH (Data Channel, that is, data channel).
In " second from generation to generation 4.0 editions, 66 pages, 71 pages, 86 pages, in March, 2002 of コ one De レ ス Electricity Words シ ス テ system, ARIB RCR STD-28, Choi team legal person Electricity ripple シ ス テ system development セ Application タ one ", the super frame structure, the expansion physical slot by time that record the definition of USCCH, descending logical control channel are the structure of USCCH (2).
In " 3GPP2C.S0084-002-0 Version2.0,3-5 page or leaf, in July, 2007,3RDGENERATION PARTNERSHIP PEOGECT2 ", record the using method that collecting mail in the UMB system (letter) used channel.
In above-mentioned information dispensing method, each the object PS in enclosing is sent SMS message.In order to send SMS message to 1 PS, send PCH in all base stations (CS) of calling area simultaneously from ownership.Because when the quantity of object PS was more, the transmission times of PCH increased too, so the inadequate resource of the PCH that sometimes limits.At this moment, sometimes common collection of letters the (letter) because of the failure of PCH inadequate resource.In addition, when the 1st time message sink failure, can again send message, but sometimes because the impact of electromagnetism ring mirror sends also failure again, PS loses the reception distributing information.
Each CS of one is connected TCH with PS, carries out the distribution of short message at TCH.Therefore, when dispatch messages, owing to the traffic of TCH increases TCH inadequate resource of distributing to PS etc., sometimes can not carry out common transmission.In addition, owing to be distribution of information on the TCH, so regard common collection of letters the (letter) 1 time as.Its result consuming cells more during than common standby.
Calling area when Distribution Center specifies predetermined distribution, and to per 1 the PS distributing information of location register to this while calling area.Therefore, become and be called the simultaneously distribution of the wide region unit of calling area, can not be to the department store or the area distribution that further limits such as station.
In above-mentioned information dispensing method, between CS and PS, connect TCH, carry out distribution of information at TCH.Therefore, by regarding common collection of letters the (letter) 1 time as, consuming cells more during than common standby.In the many situations of distributing information, can consume a large amount of batteries.
Above problem in UMB too.

With reference to Fig. 3 to Fig. 9 embodiment 1 is described.
With reference to Fig. 3, to the system specialization from Distribution Center to the PS distributing information among the PHS.Here, Fig. 3 is the block diagram of the distribution of information of explanation PHS.In Fig. 3, the information distribution system 200 of PHS comprises the 10A of Distribution Center, EX20, CS30, PS70.In information distribution system 200, the 10A of Distribution Center determines the distribution target CS, sends information via EX20 to the distribution destination CS30-1 that is determined.CS30-1 calls out PS70-1 and the PS70-2 that belongs to own and standby.CS30-1 one receives distributing information from EX20, just information is divided into N and be equipped on N the USCCH (2) and send to PS70-1, PS70-2.And, be positive integer (natural number) at this N, " being divided into 1 " means and do not cut apart.
The structure of CS is described with reference to Fig. 4.Here, Fig. 4 is the functional block diagram of CS.In Fig. 4, CS30 has transmitting system wireless device 31, receiving system wireless device 32, radio control section 33, master control part 34, storage part 35, circuit control part 36, reaches antenna 38.Master control part 34 is stored in circuit control part 36 storage part 35 from the distributing information that EX20 receives.The free time of master control part 34 instrumentation PCH sends regularly cuts apart the information that is stored in the storage part 35, and takes out successively the described radio control section 33 that sends to.Radio control section 33 transmits the information that receives to transmitting system wireless device 31.Transmitting system wireless device 31 carries out the RF modulation and sends from antenna 38.
The structure of PS is described with reference to Fig. 5.Here, Fig. 5 is the functional block diagram of PS.In Fig. 5, PS70 has transmitting system wireless device 71, receiving system wireless device 72, radio control section 73, master control part 74, storage part 75, human-machine interface oral area 76, reaches antenna 78.Here, host interface section is display part, key input part and Speech input efferent etc.Master control part 74 will be stored in storage part 75 from the divided distributing information that CS30 receives by radio control section 33 via antenna 38 and receiving system wireless device 32.Master control part 74 1 detects the distribution of divided distributing information and finishes, and just combination is stored in the divided distributing information in the storage part 75, and the distributing information of combination is shown in human-machine interface oral area 76.
With reference to Fig. 6 distribution of information sequential between Distribution Center, switch, CS, the PS is described.Here, Fig. 6 is the sequential chart of the distribution of information between Distribution Center, switch, CS, the PS.
In Fig. 6, the 10A of Distribution Center sends information and the distributing information (T301) that can determine CS to EX20.EX20 determines CS30-1 according to distributing information, utilizes the Dch packet to CS30-1 distributing information (T302).CS30-1 stores the distributing information that receives, and be N with distributing information by 62 bitslicings that can be sent by USCCH (2), and minute N transmission in control channel (T303-1~T303-N).If PS70-1 receives all USCCH (2), then combined information shows (T304).
In information distribution system 200, the 10A of Distribution Center is not to each PS distributing information, but the 10A of Distribution Center based on the information of CS to each CS distributing information.Therefore, the 10A of Distribution Center stores the information such as the CS-ID that can determine CS, CS number.In addition, utilize existing Dch packet delivery information between EX20 and the CS30.The 10A of Distribution Center at first based on the information of CS30 to the EX20 distributing information that is registered with this CS.EX20 will be written into the Dch packet from the distributing information that Distribution Center 10 receives, and only the CS30 to appointment carries out relaying.If CS30 receives distributing information, then always storage before receiving next fresh information is if available free PCH then stops this PCH, at USCCH (2) lift-launch distributing information and send to PS70.When not carried distributing information in 1 USCCH (2) message, carve information sends.PS70 stored divided information always before receiving end, if received all information, then their combinations are shown.
The motion flow of CS is described with reference to Fig. 7.Here, Fig. 7 is the action flow chart of CS.In Fig. 7, if CS30 10 receives distributing informations from the distribution of information center, then at first be stored in oneself the memory (S51).Whether CS30 judges calling and setting (S52) in distributing information.(S52: "Yes"), send PCH and connect calling (S53) when having come common calling and setting from network.In step S52, when not coming the calling and setting of automatic network ("No"), CS30 is static with idle PCH, cuts apart at USCCH (2) and carries distributing information (S54) and send (S56) N time.CS30 then judges whether to have received newly to information (S57) from the distribution of information center.When being "Yes", abandoning old information (S58), and return step S51.When step S57 is "No", again send information (S59).And step S59 is step S54 and step 56, returns step S57.That is, not newly to information the time, CS30 repeats to send institute's canned data.This is because the PS70 demonstration information that makes the PS70 that failed to receive last time and newly move to the distribution area of CS30.
The workflow of PS is described with reference to Fig. 8.Here, Fig. 8 is the workflow diagram of PS.In Fig. 8, belong to definite CS30 and the PS70 that is in the standby receives PCH (S61) with 1.2 seconds intervals.(S62: "Yes"), connect conversation (S63), when finishing conversation (S64), the wait of again transferring to PCH information received (S61) when PS70 received common incoming information.When being "No" in step S62, judged whether distributing information (S65), when being "Yes", PS70 carries out the analysis (S66) of this distributing information.The result who analyzes judges whether the distributing information that receives newly arrives information (S67).If "Yes", the old information that PS70 will store is so far all removed (S68), the new storage (S69) to information of beginning.In step 65, if "No" is then transferred to step S61.
On the contrary, in step S67, if the distributing information that receives is not newly to arrive information ("No"), then PS70 judges whether it is the information (S70) of receiving.And, be that information identifier (aftermentioned) with reference to distributing information carries out to information or no judgement of receiving etc. newly whether.If the information of receiving ("Yes") is then still transferred to step 61.That is, abandon distributing information.In step S70, if "No", PS70 judges whether to receive (S71).If "Yes" is with all information combination demonstrations (S72) of so far storage.In step S71, if not finish receiving ("No"), then append storage (S73), and transfer to step S61.
With reference to Fig. 9 USCCH (2) message is described.Here, Fig. 9 is the message format of USCCH (2).In this embodiment, CS30 is cut apart dispatch messages and is sent to PS.Therefore, when CS30 receives dispatch messages from Distribution Center 10, need to determine to be divided into several according to the length of distributing information.In Fig. 9, the information element that can be equipped on a USCCH (2) adds up to i.e. 56 bits of 7 bytes.Wherein, 1~4 bit of the first byte is made as News Category 81,5,6 bits are made as information identifier 82,1~3 bit of 7,8 bits and the second byte is made as information Segmentation Number 83,4~8 bits of the second byte are made as information number 84, the 3rd~the 7th byte is made as distributing information 85.Here, so-called News Category 81 is that imagination CS30 utilizes USCCH (2) that many services is provided, and therefore is the information element for these services of difference.Information identifier 82 is information elements of 2 bits given in order to identify distributing information of Distribution Center.Information Segmentation Number 83 is Segmentation Numbers that CS30 will determine according to its length from the distributing information that Distribution Center 10 receives.Because PS70 once receivable user profile is maximum 131 bytes, the distributing information that CS30 once can send is 5 bytes, therefore, these information Segmentation Number needs 131/5 i.e. value more than 27, so the length of information Segmentation Number 83 is made as 5 bits (1~32).Information number 84 is numbers that CS30 uses when divided information successively addition number is sent.Therefore, the value of information number 84 is values of maximum information Segmentation Number 83, and length is made as 5 bits.
According to present embodiment, CS utilizes the PCH of idle condition to avoid inadequate resource, can suppress the common failed situation of collecting mail.Repeat distributing information by CS, lose the possibility that obtains distributing information thereby can reduce PS.By in distribution of information, not using TCH, thereby can reduce the transmission failure that caused by the TCH deficiency.So area distribution information from Distribution Center to further restriction that can be from is can be corresponding to indivedual clients' demand (for example, supermarket etc. provide the advertising message distribution service to the client who shows up).And then, can suppress the battery consumption of PS.
(embodiment 2)
With reference to Figure 10~Figure 13, Fig. 4, Fig. 5, Fig. 7 and Fig. 8 embodiment 2 is described.
Figure 10 is the figure of explanation system from Distribution Center to the travelling carriage distributing information in UMB.The basic system structure of UMB is by as the AP of base station (Access Point: access point), consist of as the AT (Access Terminal: access terminal) of travelling carriage, the base-station control apparatus of accommodating AP.In information distribution system 500, distribution destination AP is determined at distribution of information center 310, sends information via base-station control apparatus 320 to the AP330-1 that belongs to the distribution destination group 400 that is determined~AP330-4.AP330-1~AP330-4 calls out belonging to AT340 own and that be in the standby.If AP330-1~AP330-4 receives distributing information from base-station control apparatus 320, then information is divided into N and is equipped on N QPCH (Quick Page CHannel: quick paging channel) send to AT340-1~AT340-8.And N is positive integer (natural number) here, and " being divided into 1 " expression is not cut apart.
The structure of AP is described with reference to Fig. 4.Here, Fig. 4 also is the functional block diagram of AP, and the circuit control part is connected with base-station control apparatus 320.
The structure of AT is described with reference to Fig. 5.Here, Fig. 5 also is the functional block diagram of AT.
With reference to the distribution of information sequential between Figure 11 descriptive information Distribution Center, base-station control apparatus, AP, the AT.Here, Figure 11 is the distribution of information sequential chart between distribution of information center, base-station control apparatus, AP, the AT.And, for the ease of diagram, only put down in writing the AT340-7,8 that wait is connected with AP330-4 as AT.
In Figure 11, distribution of information center 310 sends information and the distributing information (T601) that can determine AP to base-station control apparatus 320.Base-station control apparatus 320 is determined AP330-1~AP330-4 according to distributing information, utilizes the IP packet to AP330-1~AP330-4 distributing information (T602~T605).The AP330-4 storing received distributing information, be N with distributing information by 29 bitslicings that can be sent by QPCH, minute N time transmission distributing information (T606-1~T607-N).If AT340-7,8 receives all QPCH, then make up demonstration information (T608, T609).
In the information distribution system 500 of present embodiment, be not distribution of information center 310 to each AT distributing information, but distribution of information center 310 based on the information of AP to each AP distributing information.Therefore, distribution of information center 310 stores the information of the IP address that can determine AP, management ID etc.In addition, use control IP packet delivery information in base station between base-station control apparatus 320 and the AP330-1~AP330-4.Distribution of information center 310 at first based on the information of AP330-1~AP330-4 to base-station control apparatus 320 distributing informations that are registered with this AP.Base-station control apparatus 320 will be from the distribution of information center 310 distributing informations that receive only relaying to the AP330-1~AP330-4 of appointment.When AP330-1~AP330-4 received distributing information, always storage before receiving next fresh information was if available free QPCH then carries distributing information and sends to AT340-1~AT340-8 to this QPCH.When not carried distributing information in a QPCH message, carve information sends.AT340-1~AT340-8 stores into always receives till the divided information, when having received all information, their combinations is shown.
The motion flow of AP is described with reference to Fig. 7.Fig. 7 is the action flow chart of CS, and difference only is described.In Fig. 7, AP330 sends QPCH in step S53.In addition, AP330 is cut apart distributing information in step S54 and is equipped on QPCH, sends distributing information by QPCH in step S56.
The workflow of AT is described with reference to Fig. 8.Here, Fig. 8 is the workflow diagram of PS, and difference only is described.The AT340 that belongs to definite AP330 and be in the standby in Fig. 8 receives QPCH in step 61 with the certain hour interval.
With reference to Figure 12 QPCH is described.Here, Figure 12 is the message format of QPCH.QPCH message format 700 comprises field 710 and length 720, at length, is written into control (LoadControl) 3 bits, collection of letters information 35 bits, is kept 6 bits formation by what identification was collected mail.
Distributing information is equipped on the situation of QPCH with reference to Figure 13 explanation.Figure 13 is the message format when distributing information is equipped on QPCH.Here, AP330 is divided into N with dispatch messages and sends to AT340.Therefore, when receiving distributing information from distribution of information center 310, need to determine QPCH is divided into several according to the length of distributing information.In Figure 13, the amount of information total that can be equipped on a QPCH is 44 bits.Its content is that to be written into control 701 be 3 bits, and information identifier 702 is 2 bits, and information Segmentation Number 703 is 5 bits, and information number 704 is 5 bits, and distributing information 705 is 29 bits.
Information identifier 702 is information elements of 2 bits given in order to identify distributing information of distribution of information center 310.Information Segmentation Number 1703 be AP will be from the distribution of information center Segmentation Number that determines according to its length of 310 distributing informations that receive.If this form, AT once receivable distributing information length are 29 bits * 32 part=928 bits=116 bytes.Information number 1704 is numbers that AP uses when addition number sends in order to divided information.
According to present embodiment, obtain the effect identical with the situation of PCH.Usage data channel not in distribution of information by utilizing the QPCH of idle condition, is avoided inadequate resource, can suppress common the collection of letters unsuccessfully take inadequate resource as reason.Repeat distributing information by AP, lose the possibility that obtains distributing information thereby can reduce AT.By usage data channel not in distribution of information, can reduce the connection failure that is caused by the data channel deficiency.If be applied to the small base station of femtocell (Femtocell) etc., then can specify AP from the distribution of information center and to the area distribution information that limits, so can be corresponding to indivedual clients' demand (providing the advertising message distribution services to the client who shows up such as supermarket etc.).And then the timing receive data of wireless receiving is carried out in the timing that only monitors in the collection of letters, that is, be not specially to carry out radio communication for receive data, so can suppress the battery consumption of AT.
According to the present invention, in mobile radio communications system, can come distributing information with channel with collecting mail.
