Embodiment

Below in conjunction with the accompanying drawing in the present invention, be clearly and completely described the technical scheme in the present invention, obviously, described embodiment is only a part of embodiment of the present invention, instead of whole embodiments.Based on the embodiment in the present invention, those of ordinary skill in the art, not making the every other embodiment obtained under creative work prerequisite, belong to the scope of protection of the invention.

For make the public to of the present invention realize easier to understand, before introducing the present invention, first the paging related mechanism of LTE system and UMTS (Universal Mobile Telecommunications System, universal mobile telecommunications system) system is described.

(1) paging mechanism of LTE system

In existing LTE system, the operation of paging comprises: EUTRAN (Evolved UniversalTerrestrial Radio Access Network, the Universal Terrestrial wireless access network of evolution) to UE (UserEquipment, subscriber equipment) send Paging message, as shown in Figure 1.The information unit wherein comprised in Paging message as shown in Figure 2.

In fig. 2, wherein mainly comprise PagingRecordList, and contain the paging (such as, maximum can be 16 users) of multiple user in PagingRecordList, the content that each paging record comprises as shown in Figure 3.For the PagingUE-Identity of Fig. 3, TMSI (Temporary Mobile Subscriber Identity can be comprised in PagingUE-Identity, temporary mobile subscriber identity) or IMSI (International Mobile Subscriber Identity, international mobile subscriber identity), as shown in Figure 4.

Concrete, in LTE system, Paging message is by PDCCH (Physical DownlinkControl Channel, Physical Downlink Control Channel) PDSCH (the Physical Downlink SharedChannel that indicates, Physical Downlink Shared Channel) carry, wherein PDCCH by P-RNTI (Paging Radio Network Temporary Identity, pager wireless net network temporary mark) scrambling for dispatching the PDCCH of Paging message.

In LTE system, the time of base station calling UE is relevant to several factors below, and wherein, the time is two parameters (radio frames numbering i, subframe numbering j);

1) IMSI (that only gets wherein is low 10, and namely IMSI mod 1024, is designated as UE_ID) of user;

2) and the DRX of user (discontinuous reception) configuration, be designated as T, its span be 32,64,128,256}, unit is radio frames;

3) and can send the number of paging subframe of paging under each community 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}.Such as, when there being 1 paging subframe in each radio frames, then nB value is T; Such as when there being 2 paging subframes in each radio frames, nB value is 2T; When there being 1 paging subframe in every 4 radio frames, then nB value is T/4.

Concrete, the computing formula of the delivery time (be also that network side sends the moment of Paging to this UE simultaneously, can be subdivided into radio frames numbering i, subframe numbering j) of the Paging that UE side is monitored comprises:

(1) UE needs the radio frames numbering i monitored will meet following formula

SFN mod T=(T div N) * (UE_ID mod N) formula 1

Wherein N=min (T, nB)

(2) UE needs the subframe numbering j monitored will meet following formula:

First i_s is calculated, as shown in Equation 2:

I_s=floor (UE_ID/N) mod Ns formula 2

Wherein, N=min (T, nB), Ns=max (1, nB/T)

Secondly, final subframe numbering is determined, due to FDD (Frequency DivisionDuplex, Frequency Division Duplexing (FDD)) system and TDD (Time Division Duplex according to i_s, time division duplex) system difference, then the corresponding relation of the two is respectively table 1 and table 2:

Table 1, 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 above-mentioned moment is described below in conjunction with a concrete example.

Suppose certain LTE TDD system, UE is positioned at community A, and in the A of community, each radio frames has 2 paging subframes, i.e. nB=2T.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, obtain the radio frames numbering demand fulfillment that this UE needs to monitor: SFN mod 32=8

According to formula 2, obtain i_s=0, by inquiry table 1 above, as Ns=2, the final paging subframe that i_s=0 is corresponding is subframe 0.

That is, this UE needs be numbered 8,40,72, and monitor subframe 0 in the radio frames of 104 grades, it is also in these moment that network side sends 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 similar, namely the paging for terminal is triggered by network side, RNC (Radio Network Controller, radio network controller) tissue Paging message, carry paged UE ID (can be IMSI, TMSI etc.) in this Paging message; Base station equipment receives paging information, then carry out the paging to terminal.

Concrete, the paging of base station to terminal jointly completes by PICH (Paging Indicator Channel, Page Indication Channel) channel with PCH (Paging Channel, the paging channel) channel of its pairing.Wherein, PICH channel not bearing call message, but need to match with transmission channel PCH to use, be used to indicate specific UE the need of understanding the PCH channel of following thereafter.

Content in this PICH channel is made up of a series of paging indicator (Indicatior), and 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 computational methods.

The terminal being in idle pulley must monitor PICH channel, bit in the paging indicator Pi that the paging terminal grouping received is corresponding is complete 1, then terminal need to receive this PICH channel after paging subchannel in paging block, to determine the paging whether comprised in beep-page message this UE; Otherwise if Pi value is full 0, then terminal can ignore PCH data block thereafter.

Similar with LTE system, in the umts system, the terminal being in idle pulley, in order to reach the object of power saving, is also adopt DRX (discontinuous reception) Mode listen PICH channel.Certainly, in actual applications, the concrete moment of monitoring PICH channel also calculates according to specific formula.

A kind of method of calling is provided in the embodiment of the present invention two, the application of this method of calling in the umts system, the paging for MTC device is triggered by network side, and send Paging message (because network side sends beep-page message by eating dishes without rice or wine to UE to MTC device, namely this beep-page message is RRC Paging message, in the embodiment of the present invention for convenience of description, be described for Paging message), and the Paging message in the embodiment of the present invention is for one group of MTC device, namely network side sends Paging message to one group of MTC device.The method comprises the following steps:

(1) network side carries out the design of physical layer scheduling Paging message

At HSDPA (High Speed Downlink Packet Access, high-speed slender body theory) process in, when have for the downlink data of certain MTC device need send time, then network side needs by HS-SCCH (High Speed Shared Control Channel, High-Speed Shared Control Channel) channel dispatches relevant MTC device, and will comprise H-RNTI corresponding to this MTC device in this HS-SCCH channel; After MTC device receives HS-SCCH channel and is decoded to corresponding H-RNTI, just start to receive the downlink data carried in follow-up HS-PDSCH (High Speed Physical Downlink Shared Channel, down high speed Physical Shared Channel) channel.

And in the embodiment of the present invention, consider the packet paging to MTC device, similar process can be applied to one group of MTC device (conveniently to describe, in subsequent process, one group of MTC device is called MTC device group, namely there is the MTC device of identical Group-ID) in the process of calling optimization, such as, indicate the paging to MTC device group by HS-SCCH channel, and carry corresponding paging information on HS-PDSCH channel; When the MTC device in MTC device group is separated after relevant H-RNTI on the hs-scch channel, then read follow-up HS-PDSCH.

Concrete, based on the above-mentioned Paging message carrying Group-ID, the mode of scheduling Paging message includes but not limited to:

1) the H-RNTI field in HS-SCCH channel is set to particular value, what be used to indicate that follow-up HS-PDSCH channel carries is Group paging information for MTC device; Namely the H-RNTI field in HS-SCCH channel is set to particular value by network side, and what indicate follow-up HS-PDSCH channel to carry by H-RNTI field is Paging message for the MTC device in group.

2) by introducing new MTC-P-RNTI, what be used to indicate that follow-up HS-PDSCH channel carries is Group paging information for MTC device.Namely, when network side sends Paging message according to Group-ID to the MTC device in group, the HS-PDSCH carrying of the HS-SCCH instruction of MTC-P-RNTI mark Paging message reserved by system is needed.Wherein, for the MTC device in MTC device group, need to monitor follow-up HS-PDSCH, and for non-MTC device, then do not need to monitor follow-up HS-PDSCH.

In summary it can be seen, network side is Group paging information for MTC device by what indicate follow-up HS-PDSCH channel to carry on the hs-scch channel, thus the calling time of instruction one group of MTC device.In the embodiment of the present invention, when introducing new MTC-P-RNTI, MTC-P-RNTI can be one, also can be multiple, can the corresponding MTC-P-RNTI of each MTC device group, also multiple MTC device group can share a MTC-P-RNTI.Further, MTC-P-RNTI is special RNTI, can be that system is reserved, or by distributing time signing, or configured by high-level signaling, or the combination in any of the above-mentioned method of salary distribution, repeat no more in the embodiment of the present invention.

Certainly, in actual applications, can also directly by using the Paging message of dedicated H-RNTI to MTC device of MTC device itself to carry out paging.

(2) network side and MTC device determination calling time

Concrete, when Paging message page based on Group-ID, determine that the mode in Paging moment includes but not limited to:

1) delivery time of Paging message is determined based on the Group-ID of MTC device.Now, the moment that all MTC device belonging to same MTC group listen to group paging is identical.

Concrete, by use paging moment computing formula (namely in above-mentioned LTE system base station calling UE time corresponding to mode, such as, formula 1 and formula 2 etc.), and UE-ID or IMSI in formula 1 is replaced with Group-ID, namely need formula 1 to replace with

SFN mod T=(T div N) * (Group-ID mod N) formula (3)

Formula 2 is replaced with

I_s=floor (Group-ID/N) mod Ns formula (4)

And the T in above-mentioned formula is the DRX that MTC group is corresponding, the DRX namely distributed in units of MTC group, wherein, all UE of same MTC group use identical DRX and Group-ID.

2) each MTC group adopts the delivery time of fixing Paging message.Wherein, this Paging moment can pre-configured by system (such as, configuration time signing, or by high-level signaling distribution etc.).Now, the moment belonging to all MTC device monitoring group paging of same MTC group is identical.

3) network side is continued to use original DRX based on UE and is configured, and the MTC device in group is determined to the delivery time of the Paging message of the IMSI based on this MTC device.When network side needs to send group paging to certain MTC group, by use paging moment computing formula (namely in above-mentioned LTE system base station calling UE time corresponding to mode), calculate the paging sub-frame set that each MTC device in MTC device group will be monitored, and each paging subframe in set sends a group beep-page message.Now, the moment belonging to all MTC device monitoring group paging of same MTC group is different, and the moment that MTC device monitors group paging is consistent with the moment of the existing paging of its monitoring.

(3) network side determines the range of transmission of Paging message

Concrete, the scope that Paging message sends includes but not limited to
