Embodiment
Below in conjunction with the accompanying drawing among the present invention, the technical scheme among the present invention is clearly and completely described, obviously, described embodiment only is a part of embodiment of the present invention, rather than whole embodiment.Based on the embodiment among the present invention, those of ordinary skills belong to the scope of protection of the invention not making the every other embodiment that is obtained under the creative work prerequisite.
For making the public easier to understand to realization of the present invention, before introducing the present invention, at first the paging related mechanism to LTE system and UMTS (Universal Mobile Telecommunications System, universal mobile telecommunications system) system is described.
(1) paging mechanism of LTE system
In the prior LTE system, the operation of paging comprises: EUTRAN (Evolved UniversalTerrestrial Radio Access Network, the general continental rise wireless access network of evolution) sends Paging message to UE (UserEquipment, subscriber equipment), as shown in Figure 1.Wherein the information unit that comprises in the Paging message as shown in Figure 2.
In Fig. 2, wherein mainly comprise PagingRecordList, and comprised a plurality of users' paging (for example, maximum can be 16 users) among the PagingRecordList, the content that each paging record comprises is as shown in Figure 3.PagingUE-Identity for Fig. 3, can in PagingUE-Identity, comprise TMSI (Temporary Mobile Subscriber Identity, temporary mobile subscriber identity) or IMSI (International Mobile Subscriber Identity, international mobile subscriber identity), as shown in Figure 4.
Concrete, in the LTE system, Paging message is by PDCCH (Physical DownlinkControl Channel, Physical Downlink Control Channel) Zhi Shi PDSCH (Physical Downlink SharedChannel, Physical Downlink Shared Channel) carries, the PDCCH that wherein is used to dispatch Paging message is the PDCCH by P-RNTI (Paging Radio Network Temporary Identity, pager wireless net network temporary mark) scrambling.
In the LTE system, the time of base station calling UE is relevant with following Several Factors, and wherein, the time is two parameters (radio frames numbering i, subframe numbering j);
1) user's IMSI (only get wherein low 10, promptly IMSI mod 1024, are designated as UE_ID);
2) and user's DRX (discontinuous reception) configuration, be designated as T, its span be 32,64,128,256}, unit is a radio frames;
3) and the number that can send the paging subframe of paging under each sub-district of system configuration in each radio frames, be designated as nB, its span is { 4T, 2T, T, 1/2T, T/4, T/8, T/16, T/32}.For example, when 1 paging subframe was all arranged in each radio frames, then the nB value was T; For example when 2 paging subframes were all arranged in each radio frames, the nB value was 2T; When in per 4 radio frames 1 paging subframe being arranged, then the nB value is T/4.
Concrete, the computing formula of the delivery time of the Paging that the UE side is monitored (also be simultaneously the moment of network side to this UE transmission Paging, can be subdivided into radio frames numbering i, subframe numbering j) comprising:
(1) the UE radio frames numbering i that need monitor will satisfy following formula
SFN mod T=(T div N) * (UE_ID mod N) formula 1
Wherein N=min (T, nB)
(2) the UE subframe numbering j that need monitor will satisfy following formula:
At first calculate i_s, as shown in Equation 2:
I_s=floor (UE_ID/N) mod Ns formula 2
Wherein, and N=min (T, nB), Ns=max (1, nB/T)
Secondly, determine final subframe numbering according to i_s, because FDD (Frequency DivisionDuplex, Frequency Division Duplexing (FDD)) system and TDD (Time Division Duplex, time division duplex) system's difference, then the corresponding relation of the two is respectively table 1 and table 2:
Table 1, the FDD system
| Ns | PO when i_s＝0 | PO when i_s＝1 | PO when i_s＝2 | PO when i_s＝3 |
| 1 | 9 | N/A | N/A | N/A |
| 2 | 4 | 9 | N/A | N/A |
| 4 | 0 | 4 | 5 | 9 |
Table 2, TDD (all UL/DL patterns)
| Ns | PO when i_s＝0 | PO when i_s＝1 | PO when i_s＝2 | PO when i_s＝3 |
| 1 | 0 | N/A | N/A | N/A |
| 2 | 0 | 5 | N/A | N/A |
| 4 | 0 | 1 | 5 | 6 |
The calculating in the above-mentioned moment is described below in conjunction with a concrete example.
Suppose certain LTE TDD system, UE is positioned at sub-district A, and each radio frames has 2 paging subframes, i.e. nB=2T among the A of sub-district.For this UE, IMSI mod 1024=40, DRX length T=32 (radio frames), then can obtain N=min (T, nB)=32, Ns=max (1, nB/T)=2.
According to formula 1, obtaining the radio frames numbering that this UE need monitor needs to satisfy: SFN mod 32=8
According to formula 2, obtain i_s=0, by inquiring about top table 1, when Ns=2, the final paging subframe of i_s=0 correspondence is a subframe 0.
That is to say that this UE need monitor subframe 0 in the radio frames that is numbered 8,40,72,104 grades, it also is at these constantly that network side is sent out paging to this UE.
(2) UMTS system paging mechanism
The paging flow process of UMTS system and the paging flow process of LTE system are similar, promptly by the paging of network side triggering at terminal, RNC (Radio Network Controller, radio network controller) tissue Paging message is carried paged UE ID (can be IMSI, TMSI etc.) in this Paging message; Base station equipment receives paging information, then carries out the paging to terminal.
Concrete, the base station is to finish jointly by PICH (Paging Indicator Channel, Page Indication Channel) channel with PCH (Paging Channel, the paging channel) channel of its pairing to the paging of terminal.Wherein, the PICH channel is bearing call message not, but need use with transmission channel PCH pairing, is used to indicate specific UE whether to need to understand the PCH channel of following thereafter.
Content in this PICH channel is made up of a series of paging indicator (Indicatior), and the paging indicator will divide into groups according to system configuration, and each terminal is according to the corresponding one group of paging indicator of certain calculation method.
The terminal that is in idle pulley must be monitored the PICH channel, bit in the corresponding paging indicator Pi of the paging terminal grouping that receives is complete 1, then terminal need receive this PICH channel interior paging subchannel of paging block afterwards, to determine whether to comprise in the beep-page message paging to this UE; Otherwise if the Pi value is complete 0, then terminal can be ignored PCH data block thereafter.
Be that in the UMTS system, the terminal that is in idle pulley also is to adopt DRX (discontinuous reception) pattern to monitor the PICH channel in order to reach purpose of power saving with like the LTE system class.Certainly, in actual applications, the moment of specifically monitoring the PICH channel also calculates according to specific formula.
Based on above-mentioned paging mechanism, and 3-G (Generation Three mobile communication system) with and long evolving system in, need to support the MTC function, in the embodiment of the invention, provide a kind of method of calling at MTC equipment.Wherein, a MTC equipment may have the part characteristic among the multiple MTC characteristic, for example, low data bulk, time are controlled, Hypomobility, low-power consumption, only support PS territory, off-line indication, disturb indication etc.And the quantity of considering MTC equipment is many, if carry out paging simultaneously, can bring the signaling load of bigger paging channel, increases the processing load of UE side simultaneously.
