Abstract
The invention discloses a method, a system and a device for activating an idle mode signaling reduction function (ISR). The ISR is activated in the process when a multimode terminal initially attaches to a 2G/3G network or an LTE/SAE (long time evolution)/(system architecture evolution) network, so the multimode terminal can move in an equivalent area consisting of an RA (routing area) in the SG/3G network and an area corresponding to a TA (tracking area) list in the LTE/SAE network without any location update at any time after the initial attachment of the multimode terminal, therefore, the network load can be reduced.
Description
Technical field
The present invention relates to the communications field, relate in particular to method, system and the equipment of a kind of activation idle pulley signaling reduction scheme (Idle mode signaling reduction function, ISR).
Background technology
At Long Term Evolution standard (Time Division Long term evaluation, LTE)/System Architecture Evolution (SAE) network design period, adjacent or overlapping situation may appear in the overlay area of LTE/SAE network and existing 2G/3G network.For supporting LTE/SAE network and universal mobile telecommunications system (Universal Mobile Telecommunications System, UMTS) multimode terminal, after multimode terminal is attached to a kind of network, multimode terminal will carry out continually cell reselection in LTE/SAE network signal and 2G/3G network signal overlapping region or adjacent area.In order to reduce the position update flow of multimode terminal in LTE/SAE network and 2G/3G network signal overlapping region or adjacent area, save system resource, the ISR technology has been proposed at present.
The main thought of ISR technology is that the tracing area (TA) of the routing update (RA) of adjacent or overlapping 2G/3G network and LTE/SAE network is set as to the equivalent position district, and multimode terminal is moved or does not need to carry out position update flow during cell reselection again in equivalent zone.As shown in Figure 1, when multimode terminal is attached to a network, activate the ISR function by tracking area update (TAU) or routing region updating (RAU) flow process, Serving GPRS Support Node (Serving GPRS Support Node in while 2G/3G network, SGSN) and the support Mobility Management Entity (MME) in the LTE/SAE network all be registered to respectively home signature user server (Home Subscriber Server, HSS), multimode terminal is preserved the international mobile subscriber identity (P-IMSI) that distributed by SGSN/Route Area code (RAI) and the temporary mark (GUTI) of the UE that distributed by MME/station location marker (TAI).Now, TA list 1 corresponding region (namely 2G/3G network and LTE/SAE network overlapping region) of the zone of the RA1 in the 2G/3G network and LTE/SAE network can be regarded as an equivalence zone.When multimode terminal moves around in equivalent zone, due to for this multimode terminal, the built vertical incidence relation of 2G/3G network and LTE/SAE network, therefore, multimode terminal does not need recurrence to initiate registration, renewal process when mobile, to reduce the purpose of position update flow.
Turning to and be attached to SGSN (or MME) from MME (or SGSN) at multimode terminal, when MME and SGSN activate ISR for this bimodulus, multimode terminal can be attached on MME and SGSN simultaneously, and the periodical position renewing timer in independent operating SGSN territory and MME territory in multimode terminal, and carry out independently periodic location update in each territory.On the other hand, MME carries out associated with the control plane address that SGSN can preserve mutually the other side.During a paging multimode terminal in MME or SGSN, S-GW will initiate paging to multimode terminal in two log-on fields of MME and SGSN simultaneously; As page response, multimode terminal only need be initiated " Service Request " flow process normally and be triggered the transmission of upstream data, and without carrying out position updating process.
At present, in the situation that the network integration is disposed, the activation of the negotiation of ISR ability and ISR function is to be undertaken by general packet wireless service tunnel protocol (GTPv2) message based on version 2 on the S3 mouth between SGSN and MME, and SGSN and MME " Context Response/ACK " message mutual by context is carried out the negotiation of ISR ability and the activation of ISR function.The SGSN that the multimode terminal of take adheres to from source switches to MME as example, as shown in Figure 2, is the schematic diagram of the activation of the negotiation of carrying out the ISR ability in the RAU flow process and ISR function.
From the schematic diagram of Fig. 2, can find out, after multimode terminal is attached to MME, MME need to be registered to HSS, and now, multimode terminal has completed the attaching process in the LTE/SAE network.Afterwards, when the 2G/3G system is arrived in the multimode terminal gravity treatment, can initiate RAU request (RAU Request) to the SGSN originally adhered to; SGSN sends context request (Context Request) to MME, and whether MME will self support information (ISR capability) notice of ISR to SGSN by context response (Context Responsible) message; SGSN at context, reply immediately in (Context ACK) message carry that " ISR Actived " field activates and MME between ISR, now, SGSN also registers in HSS, MME and SGSN store mutually the other side's ID, SGSN accepts (RAU Accept) message by RAU the state of activation of ISR is notified to multimode terminal, completes the RAU flow process.
Multimode terminal is from SGSN then the TAU flow process while being attached to MME is similar with the schematic diagram of Fig. 2.
By the scheme shown in Fig. 2, after the network of multimode terminal in being attached to 2G/3G network or LTE/SAE network, when the cell reselection between different system occurs in multimode terminal, multimode terminal need to be carried out once the TAU between different system or the RAU flow process activates the ISR function according to the scheme shown in Fig. 2, after this, multimode terminal could move and without carrying out the position renewal in the equivalence zone shown in Fig. 1.
In above-mentioned ISR activation scheme, when the TA zone of administering at MME and SGSN and RA zone activation ISR function, also to need multimode terminal to carry out again TAU after initially being attached to network or the RAU flow process activates the ISR function, therefore, after the network be attached at multimode terminal, but carrying out before TAU or RAU flow process activate the ISR function, may produce the position update flow between different system, cause network load larger.

Step 502:SGSN sends Identification Request to MME, and utilizes extended field SGSN_ISR capability to carry the sign whether SGSN possesses the ISR function.
The concrete implementation of this step is as follows:
After SGSN receives the Attach Request message from multimode terminal, at first detect the core net capability set of multimode terminal, differentiate multimode terminal and whether possess the ISR ability, if multimode terminal does not possess the ISR function, follow-up flow process alternately, no longer for this multimode terminal, is carried out negotiation and the activation of ISR ability according to the attachment flow of 3GPP standard 23.060 Plays; If multimode terminal possesses the ISR function, further check again P-TMSI or the RAI parameter of whether having carried multimode terminal in Attach Request message, if do not comprise P-TMSI or RAI parameter in Attach Request message, and only contain the IMSI of multimode terminal, follow-up flow process is come alternately according to the attachment flow of 3GPP standard 23.060 Plays, carries out negotiation and the activation of ISR ability for this multimode terminal in can only the TAU/RAU flow process between different system.If contain P-TMSI or the RAI parameter of multimode terminal in Attach Request message, SGSN deduces out the address information of source node from P-TMSI or RAI parameter, and definite source node is MME or SGSN.
SGSN sends Identification Request to source node, and passes through the IMSI of Identification Request to source node request multimode terminal.Especially, if source node is MME, a field SGSN_ISR Capability of expansion in Identification Request, be used for notifying the current SGSN of MME whether to possess the ISR function.
Step 503:MME determines when self and SGSN possess the ISR function, returns to Identification Response to SGSN, and the field in this Identification Response is expanded, and utilizes the field of expansion to return to ISR Activied.
The concrete implementation of this step is as follows:
