Abstract
The invention discloses a network side processing method during user switching, which is applicable to UE (user equipment) which does not bear the context. The method comprises the following steps that: after a first network receives an attach request message sent by the UE, the first network determines that the UE starts ISR between the UE and a second network, and sends information of instructing the UE to start the ISR (idle-mode signaling reduction) between the UE and the second network to the UE. The technical proposal provided by the invention can start the ISR in attach flow. For an E-UTRAN network, a mobility management network element is MME; and for a GERAN/UTRAN network, a mobility management network element is SGSN.
Description
Technical field
The present invention relates to communication technical field, particularly network side processing method, network element device and network system in the subscriber handover process.
Background technology
The core net of wireless evolution network mainly comprises mobile management network element (Mobile Management Entity, MME), gateway (Serving Gateway, S-GW), grouped data network gateway (packet Data Network Gateway, PDN-GW) three logic function bodies, wherein, MME is mobile management entity, be responsible for Non-Access Stratum (NonAccess, NAS) signaling is encrypted and roaming, the functions such as tracking, distributing user temporary identity sign, safety function etc., it is corresponding to current universal mobile telecommunications system (Universal Mobile Telecommunication System, UMT S) the control plane part of inner Serving GPRS Support Node (Serving GPRS Support Node, SGSN).S-GW is responsible for local mobility anchor point and mobility anchor point and the Lawful Interception relevant information of 3GPP internal system; P-GW then is responsible for strategy execution and charging and Lawful Interception correlation function.
A demand of evolvement network is saving signaling or limitation signaling (the Idle mode signalling reduction that realizes under the idle pulley, ISR) function, it mainly is the mobile management flow process of subscriber equipment (UE) between different access networks that reduces under the idle pulley.When for example UE switches to the LTE network from the UMTS network, reduce Inter 3GPP Access System Mobility in Idle State and process.
If UE will not initiate Attach flow process rather than position update flow when having bearer context among the UE under the prior art when UE moves to first network after the second network registration in first network.First network can be UMTS Terrestrial radio access network (the Evolved UMTS Territorial Radio Access Network of evolution, E-UTRAN), second network can be GSM EDGE Radio Access Network (GSM/EDGE Radio Access Network, GERAN)/land radio access web (UMTS Territorial Radio Access Network, UTRAN).
Consult Fig. 1, the attachment flow figure during for prior art one UE access first network, concrete attaching process comprises:
Step 101-step 102, UE send Attach Request message to the MME in the first network.
Step 103, MME send to the SGSN in the second network and identify the IMSI that asks Identification Request message to ask for UE, and SGSN sends to MME and identifies response Identification Response message.
Step 104, when SGSN can not identify UE, do not have the IMSI of UE in the Identification Response message, MME sends Identify Request to UE and asks for IMSI, UE returns Identify Response message to MME.
Step 105, MME are judged the bearer context whether UE is arranged, if not then carry out authentication, execution in step 107 is if having the bearer context of UE then carry out 106.
The process of the bearer context of step 106, MME deletion UE.
Step 107, MME send the position to HSS and upgrade Update Location, and MME ID is registered among the HSS.
Step 108, HSS send canceling position Cancel Location message to SGSN, the context of request deletion UE.
The process of the bearer context of step 109, SGSN deletion UE.
Step 110, HSS insert subscription data to MME, and comprising signatory default APN APN, MME checking UE replys response to HSS in this step after the legitimacy in registration TA zone.
Step 111-step 115, set up the process of default bearer.
Step 116, MME return to adhere to eNodeB and accept Attach Accept message.
Step 117, eNodeB send radio bearer to UE and set up request Radio Bearer Establishment request.
Step 118, UE send radio bearer to eNodeB and set up response Radio Bearer Establishment response.
Step 119, eNodeB send to adhere to MME and finish Attach Complete message.
Step 120, MME bring S-GW with the eNodeB user plane information, set up user plane bearer between eNodeB and the S-GW.
Step 121, MME will be related with UE APN information together with the information registering of PDN-GW in HSS.
Prior art one has following shortcoming: from the attachment flow of prior art, UE will can not set up ISR mechanism in the Attach flow process.Like this will trigger position when UE gets back to second network (GERAN/UTRAN) from first network (E-UTRAN) new technological process more, cause that position update flow increases between system, can't reach the purpose of saving signaling.
In addition, under existing ISR mechanism, when UE after E-UTRAN and two kinds of networks of GERAN/UTRAN have been set up ISR mechanism, if activation, modification or the deletion of bearer context occur in UE in the current network of stopping, so when UE moves in the network of opposite end, UE can initiatively initiate the bearer context information that the TAU/AU flow process is come synchronous both sides, and prior art two provides UE to initiate the TAU/RAU flow process to come the flow process of bearer context information of synchronous both sides as follows:
Step 201, UE move in the E-UTRAN network, and the MME in E-UTRAN sends position updating request (TAU Request), carry S-TMSI, P-TMSI in this message, and Update Type is set to ISR Synch.
Step 202, MME send context request Context Request message to the SGSN in the GERAN/UTRAN network, with the context of request UE and the ISR ability of SGSN.
Step 203, SGSN send context response Context Response message, the ISR ability of carrying context and the SGSN of UE among this Context Response to MME.
Step 204, MME confirm that UE uses ISR between MME and SGSN, send context to SGSN and confirm Context Ack message, and this message indicating UE uses ISR between MME and SGSN.
Step 205, MME send the position to UE and upgrade response TAU Accept message, and this message indicating UE uses ISR between MME and SGSN.
Prior art two has following shortcoming: UE and set up the ISR connection between MME and SGSN, when the bearer context of SGSN side change (being the bearer context of having deleted UE here), UE gets back to the MME side and triggers more new technological process of executing location, MME finds not have the bearer context of UE behind the SGSN side synchronous context, so existing position update flow TAU can't rebulid default bearer.
