Step S101 ": if MME/UPE determines the current not-connected status that is in 2G/3G network and LTE of subscriber equipment; then send paging request (Paging Request) to SGSN and eNodeB respectively; wherein; SGSN need be transmitted to RNC with the paging request, RNC sends paging (Paging) to subscriber equipment; ENodeB sends paging to subscriber equipment after receiving the paging request;
Step S102 " a: if subscriber equipment is in grouping mobility management states-Idle state (PMM-IDLE) state in the 2G/3G network; then return page response (Paging Response); SGSN returns page response to MME/UPE to SGSN; and and RNC between set up RAB (RAB, Radio Access Bearer);
Step S103 " a:MME/UPE is the connection status of 2G/3G network with the status modifier of subscriber equipment;
Step S104 " a:MME/UPE sends to SGSN with user data, and SGSN is dealt into RNC with user data, and RNC is dealt into subscriber equipment with user data.
Subscriber equipment is in the processing mode of UTRAN Acceditation Area paging channel (URA-PCH, UTRAN RegisterArea Paging CHannel) state in the 2G/3G network can be with reference to step S102 " b.
Step S102 " b: if subscriber equipment is in the URA-PCH state in 3G network, then return page response to RNC, RNC returns page response to SGSN, and SGSN returns page response to MME/UPE;
Step S103 " b:MME/UPE is the connection status of 2G/3G network with the status modifier of subscriber equipment;
Step S 104 " b:MME/UPE sends to SGSN with user data, and SGSN is dealt into RNC with user data, and RNC is dealt into subscriber equipment with user data.
Subscriber equipment receives the processing mode of paging in the LTE network can be with reference to step S 102 " c.
Step S102 " c: if subscriber equipment receives paging in the LTE network, then return page response to MME/UPE;
Step S103 " c:MME/UPE is the connection status of LTE with the status modifier of subscriber equipment;
Step S104 " set up RAB (RAB Setup) between c:MME/UPE and the eNodeB;
Step S105 " c:MME/UPE is dealt into eNodeB with user data, and eNodeB is dealt into subscriber equipment with user data.

Step S406b ': S-GW is dealt into SGSN with user data, and SGSN is dealt into subscriber equipment with user data.
Above-mentioned steps S403 and subsequent step are the processing mode of SGSN when determining that subscriber equipment is in the PMM-IDLE state, determine that for SGSN subscriber equipment is in the PMM-CONNECTED state, can be with reference to step S403 ' and subsequent step.
Step S403 ':, then send user data to RNC if SGSN determines that subscriber equipment is in the PMM-CONNECTED state.Wherein, if do not set up relevant RAB between SGSN and the RNC, then SGSN before RNC transmission user data, should set up with RNC between relevant RAB.
Step S404 ' then is dealt into subscriber equipment with user data if a:RNC determines that subscriber equipment is in CELL-DCH or CELL-FACH state.
If the processing mode when determining that for RNC subscriber equipment is in the URA-PCH state can be with reference to step S404 ' b.
Step S404 ' is if b:RNC determines that subscriber equipment is in the URA-PCH state, and then S-GW returns user data, wherein, carries the indication that subscriber equipment is in the URA-PCH state in the user data.The subsequent treatment mode can be with reference to step S404a and step S404b, if just S-GW determine and eNodeB between do not exist the relevant bearer of other types user data or subscriber equipment not to be in the LTE-ACTIVE state, and trigger when subscriber equipment is initiated paging, if subscriber equipment is in the URA-PCH state, then need to return page response to SGSN, SGSN returns page response to S-GW, and S-GW is dealt into SGSN with user data, and SGSN sends user data to subscriber equipment.
Above-mentioned three preferred embodiments can be applied to set up between S-GW and the SGSN under the condition of relevant bearer, the relevant bearer of setting up between S-GW and the SGSN has a variety of modes, the relevant bearer of setting up between S-GW and the SGSN also has a lot of opportunitys, be a kind of opportunity wherein, subscriber equipment is after LTE initiates certain business, move to 2G/3G network and initiating updating of tracking area (TAU again, Tracking AreaUpdate), SGSN sets up this professional relevant bearer after obtaining the context (Context) of MME between SGSN and S-GW.Below in conjunction with Fig. 5, introduce the embodiment of the relevant bearer between a kind of S-GW of foundation and SGSN under this opportunity.
Step S501: in LTE, set up the new bearer of subscriber equipment, for example, the relevant bearer between S-GW and the eNodeB.
Step S502: after subscriber equipment moves to the 2G/3G network, initiate TAU.
Carry out context (Context Retrival) process synchronously between step S503:SGSN and the eNodeB.
Step S504:SGSN obtains the information (Info) of relevant new bearer.
Create block data protocol context (PDP Context) between step S505:SGSN and the S-GW.
Step S506:SGSN returns the TAU acceptance response to subscriber equipment.
In above-mentioned three preferred embodiments, when subscriber equipment is in the LTE-ACTIVE state, can be invalid with the bearing mark between SGSN and the S-GW, so that when down user data arrives, needn't judge whether there is relevant bearer between S-GW and the eNodeB, or whether the carrying of S-GW record is and eNodeB between carrying; When subscriber equipment is not in the LTE-ACTIVE state, S-GW record be carried as and SGSN between carrying.In addition, when subscriber equipment was in the LTE-ACTIVE state, S-GW can write down two loaded information simultaneously, when descending user data arrives, user data is dealt into and ENodeB between carrying in.
Mentioned above, above-mentioned three preferred embodiments can be applied to set up between S-GW and the SGSN under the condition of relevant bearer, in actual applications, when user data arrives S-GW, may also not set up relevant bearer between S-GW and the SGSN.For example, after activating limitation signaling, subscriber equipment is initiated a service request in LTE, and set up new carrying, comprise the carrying between S-GW and the P-GW, subsequently, subscriber equipment enters the LTE-IDLE state and enters the zone of the limitation signaling of 2G/3G network, but do not initiate any access procedure, like this, the relevant bearer between that SGSN just may not set up this business and the S-GW.When this professional down user data arrived S-GW, S-GW possibly can't directly be dealt into SGSN with user data.When flow process shown in Figure 6 is certain professional user data arrival S-GW, do not set up a kind of downlink data processing scheme under this professional relevant bearer condition between S-GW and the SGSN.As shown in Figure 6, comprising:
After step S601:S-GW receives user data, if determine with eNodeB between had the user plane bearer corresponding with described user data, then the user plane bearer of user data by described correspondence is dealt into eNodeB, eNodeB is dealt into subscriber equipment with user data.
After step S602:S-GW receives user data, if there is not the relevant bearer of user data between definite and the eNodeB, then send the message that triggers the paging request to MME, MME initiates paging to subscriber equipment, and S-GW also sends protocol Data Unit notice request (PDUNotification Request) to SGSN, further, after SGSN receives the PDU notice request, can return protocol Data Unit push-notification-answer (PDU Notification Response) to S-GW.
In step S602, because S-GW had both triggered MME and had initiated paging to subscriber equipment, send the protocol Data Unit notice request to SGSN again, so, subscriber equipment and SGSN may can have follow-up response or work of treatment, and step S603, step S603 ' a and step S603 ' b promptly are some execution modes of subscriber equipment and SGSN subsequent treatment.
Step S603: subscriber equipment returns page response to MME receive page response in LTE after.
Step S604:MME initiates to set up between S-GW and the eNodeB process of relevant bearer.
Step S605:S-GW is dealt into eNodeB with user data, and eNodeB is dealt into subscriber equipment with user data.
Step S603 is the processing mode of subscriber equipment when the paging that receives MME, for the processing mode of SGSN when receiving the protocol Data Unit notice request that subscriber equipment sends, and can be with reference to step S603 ' a and step S603 ' b.
Step S603 ' is in the PMM-CONNECTED state if a:SGSN determines subscriber equipment, then and carry out the context synchronizing process between the MME.
Create the block data protocol context process between step S604 ' a:SGSN and the S-GW.
Set up relevant RAB between step S605 ' a:SGSN and the RNC.
Step S606 ' a:S-GW is dealt into SGSN with user data, and SGSN is dealt into RNC with user data, and RNC is dealt into subscriber equipment with user data.
Step S603 ' a is the processing mode of SGSN when determining that subscriber equipment is in the PMM-CONNECTED state, and the processing mode when determining that for SGSN subscriber equipment is in the PMM-IDLE state can be with reference to step S603 ' b.
Step S603 ' then initiates paging to subscriber equipment if b:SGSN determines that subscriber equipment is in the PMM-IDLE state.
Step S604 ' b: subscriber equipment returns page response to SGSN receive page response in the 2G/3G network after.
Carry out the context synchronizing process between step S605 ' b:SGSN and the MME.
Step S606 ' b: set up relevant bearer between SGSN and the S-GW and the relevant RAB between SGSN and the RNC.This step has a variety of implementations, for example, SGSN can ask subscriber equipment to set up block data protocol context, and subscriber equipment initiate to activate block data protocol context, sets up relevant bearer between SGSN and the S-GW and the relevant RAB between SGSN and the RNC; SGSN can ask up-to-date block data protocol context to MME, and obtains the new beared information of subscriber equipment, sets up new bearer between SGSN and the S-GW and the relevant RAB between SGSN and the RNC; SGSN can also obtain the new beared information of subscriber equipment, sets up SGSN to all new bearers between the S-GW.
Step S607 ' b:S-GW is dealt into SGSN with user data, and SGSN is dealt into subscriber equipment with user data.
If when embodiment shown in Figure 6 can be applied to set up new bearer between S-GW and the eNodeB, just set up under the condition of carryings all between S-GW and the eNodeB.In actual applications, when setting up the new bearer between S-GW and the eNodeB, may only can set up and professional relevant carrying, can't set up all carryings, like this, when implementing embodiment shown in Figure 6, can do not exist between definite S-GW and the eNodeB do not have relevant bearer between relevant bearer and/or S-GW and the SGSN after, continue to judge whether the relevant bearer or the subscriber equipment that whether have other types of service between S-GW and the eNodeB are in the LTE-ACTIVE state, if, then between S-GW and eNodeB, set up relevant bearer, S-GW is dealt into eNodeB with user data, eNodeB is dealt into subscriber equipment with user data, otherwise, can carry out subsequent treatment with reference to flow process shown in Figure 6.
In flow chart shown in Figure 6, can when handling down user data, set up the relevant bearer between S-GW and the SGSN.In actual applications, also can work as subscriber equipment when in LTE, setting up new carrying, set up the relevant bearer between S-GW and the SGSN.Concrete, S-GW or MME can provide new beared information to SGSN, and SGSN can be used as S-GW Gateway GPRS Support Node (GGSN, Gateway GPRS Support Node) and carry out subsequent treatment; S-GW or MME can send to SGSN and set up packet data protocol context request, are responded by SGSN.No matter S-GW provides new beared information to SGSN, still send and set up packet data protocol context request, all need to obtain the address information of SGSN, the mode of a kind of address acquisition information wherein is, when descending user data arrives, if there is not corresponding carrying, then S-GW searches the customer equipment context of user data correspondence, to obtain the address information of SGSN; The mode of another address acquisition information is, the address information that SGSN can search SGSN to home subscriber server (HSS, Home Subscriber server) or MME.
In actual applications, subscriber equipment has been set up new carrying and has been moved to the 2G/3G network in LTE after, can initiate access procedure immediately, Routing Area Update (RAU for example, Routing Area Update), in access procedure, SGSN can ask the latest content of subscriber equipment to MME, SGSN sets up SGSN to the new carrying that needs between the S-GW according to these information.When descending user data arrives S-GW, can carry out subsequent treatment with reference to embodiment shown in Figure 4.Need to prove, in this manner, when descending user data arrives S-GW, there is not relevant bearer if find between SGSN and the S-GW, illustrate that then therefore subscriber equipment may can not trigger the process of calling user device under the 2G/3G not in the 2G/3G network, only need to check whether subscriber equipment is in the LTE-ACTIVE state and gets final product, if subscriber equipment is not in the LTE-ACTIVE state, then only need in LTE, to trigger calling user device.
Need to prove that at last in above-mentioned all embodiment, subscriber equipment can carry out contextual renewal process in returning the page response process.
