S12, SGSN receive the Routing Area Update request message, send user's context request (Context Request) message to MME and remove to obtain the context of this UE.
S13, MME respond user's context response (Context Response) message to SGSN.
After S14, SGSN receive the user's context response message, and carry out the bi-directional authentification process between the UE.
S15, after bi-directional authentification passes through, SGSN sends user's context to MME and confirms (ContextAcknowledge) message.
S16, SGSN are to local subscribed services device (HSS, Home Subscriber Server) sends the renewal location request message, carry SGSN numbering, SGSN address and IMSI International Mobile Subscriber Identity information such as (IMSI, Temporary Mobile Subscriber Identity) in this message.
S17, HSS send cancel location message to MME after receiving and upgrading location request message, and MME carries out respective operations and responds the canceling position acknowledge message to HSS.
S18, HSS send to SGSN and upgrade the position acknowledge message.
After S19, SGSN receive and upgrade the position acknowledge message, distribute new mobile area list and packet TMSI (P-TMSI for this UE, Packet Temporary Mobile SubscriberIdentity), and new mobile area list RA List and P-TMSI be handed down to this UE.
S20, after this UE receives that SGSN is the P-TMSI of its distribution, send routing update to SGSN and finish message.

As shown in Figure 3, the two HSS that are registered to of SGSN of the connecting system that leaves for the MME of the current place of UE in embodiment of the invention connecting system and UE the last time, realize UE when idle condition, the process chart of purpose is moved in the position of not having Signalling exchange, comprises step:
S21, detect when having entered a new lane place from SGSN route district as UE, and this band of position is in SGSN is not the zone of the UE RA List sign of distributing.
S22, this UE initiate location area updating request (TAU Request) message to eNodeB, eNodeB passes on the MME of this message in the connecting system of the current place of UE then, carrying SGSN in this message is packet TMSI (P-TMSI, Packet Temporary MobileSubscriber Identity), RAI and the activation sign (active flag) that UE distributes.
After S23, this MME receive the location area updating request message, be the P-TMSI of UE distribution and the address that RAI obtains SGSN based on SGSN in this message; Send user's context request (Context Request) message to SGSN then and remove to obtain the context of this UE, this request message carries original RAI and P-TMSI and idle state signaling optimization indication (ISSO indication, Idle State SignalingOptimization indication) information such as, wherein ISSO indication be used to identify MME whether have support UE under idle condition in the overall area of the band of position tabulation sign that MME and SGSN distribute respectively, do not have the ability that move the position of Signalling exchange.
S24, after SGSN has obtained the context request of this UE, respond user's context response (Context Response) message to MME, carry user's context in this message, information such as subscription data (SubscriptionData) and ISSO indication, wherein user's context comprises IMSI International Mobile Subscriber Identity (IMSI, Temporary Mobile Subscriber Identity), original P-TMSI and RA List, authentication parameter group (Authentication Quintets), bearer context (bearer contexts), gateway Signal Message Address (Serving GW signaling Address) and Tunnel End Point Identifier (TEID (s)).
In this step, the ISSO indication that carries in this message be used to identify SGSN and MME whether have support UE under idle condition in the overall area of the band of position tabulation sign that MME and SGSN distribute respectively, the negotiation result of not having the ability that the position of Signalling exchange moves, if in above-mentioned S23, the ISSO indication that carries in the user's context request message that MME sends, be designated MME have support (Support) UE under idle condition in the overall area of the band of position tabulation sign that MME and SGSN distribute respectively, there is not the ability that move the position of Signalling exchange, and when SGSN also has this ability, then the ISSO indication in the context response information responded of SGSN be designated the negotiation result of SGSN and MME be both sides all have supports (Support) UE under idle condition in the overall area that the band of position tabulation that MME and SGSN distribute respectively identifies, do not have the ability that move the position of Signalling exchange; Otherwise it is that both sides do not support that the ISSO indication in the context response information that SGSN responds is designated the negotiation result of SGSN and MME.
After S25, MME receive the user's context response message, and carry out the bi-directional authentification process between the UE.
S26, after bi-directional authentification passes through, MME sends the response user's context to SGSN and confirms (ContextAcknowledge) message, carry SGSN and MME in this message and whether have and support under the UE idle condition in the overall area of the band of position tabulation sign that MME and SGSN distribute respectively, do not have the negotiation result of the ability that the position of Signalling exchange moves.
S27, if it is that both sides have under supports (Support) the UE idle condition in the overall area that the band of position tabulation that MME and SGSN distribute respectively identifies that the ISSO indication in the context response information that SGSN responds in above-mentioned S24 is designated the negotiation result of SGSN and MME, there is not the ability that move the position of Signalling exchange, then SGSN is to gateway (S-GW, user plane terminating point when Serving Gateway) sending request user terminal idle condition changes to user plane update request (the User Plane Update Request) message of gateway from service universal grouping wireless business supporting node, carry block data protocol context (the PDP Context of UE in this message, Packet Data ProtocolContext) SGSN user plane tunnel endpoint (TEID, Tunnel End Point Identifier), and TEID be made as zero.
S28, S-GW respond user plane to SGSN and upgrade response (User Plane Update Response) message.After this, if S-GW receives from grouped data network gateway (PDN GW, Packet Data NetworkGateway) downlink data to the user terminal that is in idle condition of Fa Songing, then S-GW stores this downlink data, and notifies SGSN and MME that this user terminal is carried out paging.
S29, MME sends to HSS and upgrades position (Update Location) request message, if the ISSO indication in the context response information that SGSN responds in above-mentioned S24 be designated the negotiation result of SGSN and MME be both sides all have supports (Support) UE under idle condition in the overall area that the band of position tabulation that MME and SGSN distribute respectively identifies, do not have the ability that move the position of Signalling exchange, then carry the MME address in this request message, being used to indicate HSS to keep SGSN is that UE continues the indication information (this indication information can be the SGSN address) of service and user's information such as IMSI.
After S30, HSS received and upgrade location request message, keeping SGSN based on indication HSS was the indication information that UE continues service, and cancellation sends canceling position (Cancel Location) message to SGSN; Then send and upgrade location confirmation (Update Location Ack) message to MME.
After S31, MME receive the renewal position acknowledge message of HSS, for UE distributes new TA list and S-TMSI, and to UE transmission location area updating acceptance (TAU Accept) message, carry MME in this message and be new TA list, S-TMSI that UE distributes, and the information such as RA List, P-TMSI that in S24, from the user's context that SGSN sends, obtain of MME.
S32, UE receiving position district upgrade and accept message, and, determine self to possess the position mobility (confirming that the idle state signaling optimizational function is activated) that does not have Signalling exchange in the band of position of two mobile area lists signs that when idle condition, issue at this based on RA List, the P-TMSI, TA List, the S-TMSI that obtain; UE can identify in self EMS memory self possesses this ability, follow-up like this UE is in this TA list and determined lane place of RA List and route district when mobile, just can be according to the sign in this internal memory, need not to MME or renewal of SGSN executing location district or Routing Area Update operation, thereby move the position of realizing the no Signalling exchange of idle condition.After finishing dealing with, the position renewal can also respond location area updating to MME and finish (TAU Complete) message based on the S-TMSI that obtains.
In above-mentioned S24, the ISSO indication that SGSN carries in context response (Context Response) message that MME responds, in order to sign SGSN and MME whether have support UE under the idle condition in the overall area of the band of position tabulation sign that MME and SGSN distribute respectively, do not have the negotiation result of the ability that the position of Signalling exchange moves, the concrete deterministic process of this ISSO indication is as follows:
If the ISSO indication that carries in the context request message that MME sends be designated have supports (Support) UE under idle condition in the overall area that the band of position tabulation that MME and SGSN distribute respectively identifies, when not having the ability that the position of Signalling exchange moves, and when SGSN also has this ability, then the ISSO indication in the context response information responded of SGSN is designated: the negotiation result of SGSN and MME be both sides all support (Support) UE under idle condition in the overall area of the band of position tabulation sign that MME and SGSN distribute respectively, do not have the position of Signalling exchange and move processing;
If the ISSO indication that carries in the context request message that MME sends be designated have supports (Support) UE under idle condition in the overall area that the band of position tabulation that MME and SGSN distribute respectively identifies, when not having the ability that the position of Signalling exchange moves, but when SGSN does not have this ability, then the ISSO indication in the context response information responded of SGSN is designated: the negotiation result of SGSN and MME be do not support (Not Support) UE under idle condition in the overall area of the band of position tabulation sign that MME and SGSN distribute respectively, do not have the position of Signalling exchange and move processing;
If the ISSO indication that carries in the context request message that MME sends be designated (Not Support) UE that do not have supports under idle condition in the overall area that the band of position tabulation that MME and SGSN distribute respectively identifies, when not having the ability that the position of Signalling exchange moves, then no matter whether SGSN has this ability, the ISSO indication that carries in the context response information that SGSN responds all is designated: the negotiation result of SGSN and MME be do not support (Not Support) UE under idle condition in the overall area of the band of position tabulation sign that MME and SGSN distribute respectively, do not have the position of Signalling exchange and move processing.
ISSO indication in the context request message that above-mentioned MME sends, configuration information based on operator determines in advance, if operator opened UE under the idle condition in the overall area of the band of position tabulation sign that MME and SGSN distribute respectively, when not having the position locomotive function of Signalling exchange, this ISSO indication that then carries in the context request message of Fa Songing be set to have support (Supported) UE under idle condition in the overall area of the band of position tabulation sign that MME and SGSN distribute respectively, do not have the ability that move the position of Signalling exchange; Otherwise be set to not have.
