Embodiment

To combine the accompanying drawing in the embodiment of the invention below, the technical scheme in the embodiment of the invention is carried out clear, intactly description, obviously, described embodiment only is the present invention's part embodiment, rather than whole embodiment.Based on the embodiment among the present invention, those of ordinary skills are not making the every other embodiment that is obtained under the creative work prerequisite, all belong to the scope of the present invention's protection.

The control method flow chart of the synchronous context that Fig. 1 provides for first embodiment of the invention.The executive agent of present embodiment can be network side node.As shown in Figure 1, present embodiment comprises:

The service request of step 11, reception subscriber equipment.

The service request of subscriber equipment can comprise: attach request of user equipment or position updating request etc.

Step 13, when the attribute of the network side node that receives said service request is the association node of first network and second network, to subscriber equipment sending node attribute information.

Wherein, the node attribute information of sending to subscriber equipment can supply said subscriber equipment under activating idle condition, during signaling reduction function (ISR), to carry out first network and the contextual triggering control of second inter-network synchronization according to said node attribute information.Need to prove that subscriber equipment is not limited only to carry out the triggering control of synchronous context according to the node attribute information that receives, and also may be used in other application scenarioss.

Node attribute information is carried in the position and upgrades and to accept message or adhere to and accept to send in the message subscriber equipment.

The described associating of the embodiment of the invention (Combo) node also can be described as the unification node, comprises two parts: the first server net node section (below be called: the first network partial node) and the second server net node section (below be called: the second network partial node).In the network design process, the first network partial node and the second network partial node that association node comprises can use same hardware platform, and the mutual employing internal interface between the first network partial node and the second network partial node is realized.Therefore, the first network partial node and the second network partial node can keep UE contextual synchronously in real time through internal interface, and need not obtain the up-to-date context of UE through the interface of external perimysium referenceization, thereby have reduced the Signalling exchange between the network node.

On the basis of technique scheme, association node can activate UE at first network and the second internetwork ISR, and the announcement information that ISR is activated send to UE in the attachment flow or location area updating flow process of subscriber equipment.Further; Send in the announcement information of ISR activation to UE at association node; Also can be in the announcement information that an ISR activates, the wireless access information (RAT information) of carrying two networks: first wireless access information of first network and the second wireless access information of second network.

The inventor finds in realizing embodiment of the invention process; Prior art UE can't be known the attribute of the network side node of current access; Therefore; No matter network side node is association node or network node independently, and the node that subscriber equipment all will activate ISR is regarded two independently network nodes and carry out the triggering control of synchronous context as.At this moment; If UE has activated ISR; And the carrying of UE in first network changes and when the registration area of first network moved to the registration area of second network, UE can initiate the location area updating flow process of second network, the location area updating flow process that the second network based UE triggers; Obtain the up-to-date context of UE to associated NE, thereby realize that UE is contextual synchronously in first network and second network.If the network side node of the current access of UE is an association node; Because it is contextual synchronous in real time that association node inside can keep; At this moment; If UE still comes synchronous context according to the triggering mode of isolated node, then will cause signaling consumption unnecessary between network side node and the UE, be unfavorable for the interface-free resources of the system of practicing thrift.

What be different from prior art is that when present embodiment was association node at the attribute of the network side node that receives service request, to subscriber equipment sending node attribute information, the network side node of the current access of notifying user equipment was an association node.UE can have the function of real-time synchronous context according to association node; When UE activates ISR; Carry out the contextual triggering control of first network and second inter-network synchronization; For example: if UE has activated ISR, when UE changes and moves to the registration area of second network from the registration area of first network in the carrying of first network, because the network side node of the current access of UE is an association node; Even UE in the carrying of first network change has taken place, UE can not obtain the up-to-date context of UE in order to trigger second network to first network to second network initiation location area updating flow process this moment yet.Therefore, present embodiment has been practiced thrift the signaling consumption between association node and the UE, thereby has been helped the interface-free resources of the system of practicing thrift after UE inserts association node and activates ISR.

The control method flow chart of the synchronous context that Fig. 2 provides for second embodiment of the invention.Be different from embodiment shown in Figure 1, the executive agent of present embodiment can be subscriber equipment.As shown in Figure 2, present embodiment comprises:

Step 21, send service request to network side node.

Step 23, receive the node attribute information from said network side node, said node attribute information is used to represent that said network side node is the association node of first network and second network.

If receiving the network side node of service request is association node, association node can be an association node in order to the network side node of notifying the current access of UE to UE sending node attribute information.Node attribute information is carried in attached to accepting adhering to of network side node transmission and sends to UE in message or the position renewal reception message.

Step 25, under activating idle condition, during signaling reduction function (ISR), carry out first network and the contextual triggering control of second inter-network synchronization according to said node attribute information.

Wherein, UE carries out first network according to node attribute information and the contextual triggering control of second inter-network synchronization can comprise: when node attribute information representes that the network side node of the current access of UE is association node; If UE has activated ISR; So; Even the carrying of UE in first network changes and when moving to the registration area of second network, also do not initiate the triggering flow process of synchronous context to second network, the triggering flow process of synchronous context can comprise the location area updating flow process that UE initiates to network side node.In fact; Because the network side node of the current access of UE is an association node; Therefore; Can keep UE contextual synchronously in real time through the internal interface of association node between first network node that association node comprises and second network node, not obtain the up-to-date context of UE to another network node and do not need UE to trigger a certain network node.

On the basis of technique scheme; When said service request comprises attach request or position updating request; It is the announcement information that the ISR of the network side node of association node activates that UE can receive from attribute; Said announcement information comprises the first wireless access information of said subscriber equipment at said first network, and/or said subscriber equipment is in the second wireless access information of said second network.

Present embodiment UE can know whether the network side node of current access is association node when receiving the node attribute information of network side node transmission.When if UE knows that according to the node attribute information that receives the network side node of current access is association node; Can have the function of real-time synchronous context according to association node; When UE activates ISR; Carry out the contextual triggering control of first network and second inter-network synchronization; For example: if UE has activated ISR, when UE changes and moves to the registration area of second network from the registration area of first network in the carrying of first network, because the network side node of the current access of UE is an association node; Even UE in the carrying of first network change has taken place, UE can not obtain the up-to-date context of UE in order to trigger second network to first network to second network initiation location area updating flow process this moment yet.Therefore, present embodiment has been practiced thrift the signaling consumption between association node and the UE, thereby has been helped the interface-free resources of the system of practicing thrift after UE inserts association node and activates ISR.

Fig. 3 is the control method embodiment application scenarios LTE/SAE schematic network structure of synchronous context of the present invention.As shown in Figure 3; At long-term evolving network/System Architecture Evolution network (Long TermEvolved/System Architecture Evolved; Be called for short LTE/SAE) in; Mainly comprise: universal terrestrial access network (the Evolved UniversalTerrestrial Radio Access Network of mobile management network element (Mobility Management Entity is called for short MME), SAE gateway (SAEGateway is called for short SAE GW), evolution; Hereinafter to be referred as E-UTRAN) in evolution base station (Evolved Node B; Hereinafter to be referred as eNB), service universal packet wireless business be engaged in (General PacketRadio Service is called for short GPRS) support node (Serving GRPS Support Node is called for short SGSN), policy charging rule function network element (Policy and Charging Rules Function; Be called for short PCRF) and home subscriber data server (Home Subscriber Server is called for short HSS) etc.

HSS is the permanent storage place of user contracting data, is usually located at the home network that the user contracts.

In the application scenarios shown in Figure 3, when carrying out network design in operator, MME and SGSN can use same hardware platform, and at this moment, the network node that MME and SGSN form is associating (Combo) node, and association node also can be described as the unification node.Under this situation; Association node comprises MME part and SGSN part; Carry out alternately through the internal interface between the association node between MME part and the SGSN part; Thereby MME part partly goes up the UE context of preserving with SGSN and can keep in real time synchronously, thereby practices thrift the MME part or SGSN partly obtains the required signaling consumption of the up-to-date context of UE to other network elements (as: HSS).

Embodiment below respectively is detailed all is with application scenarios shown in Figure 3 is example, and the technical scheme of the embodiment of the invention is described.Respectively detail among the embodiment following, the 2G/3G network is first network of the embodiment of the invention; The LTE network is second network of the embodiment of the invention; The network side node that core net node SGSN in the 2G/3G network and the unification of the core net node MME in the LTE network are formed is the association node of the embodiment of the invention; Wherein, The SGSN that association node comprises partly is the first network partial node of the embodiment of the invention, and the MME that association node comprises partly is the second network partial node of the embodiment of the invention.

The inventor finds in realizing embodiment of the invention process; Though network side MME part and SGSN partly form association node; But as far as UE; MME that association node comprises part and MME (non-Combo node) independently do not have the difference of essence, and the SGSN part that comprises of association node and SGSN node (non-Combo node) independently do not have the difference of essence, that is: can't to discern the network side node of current access be that association node also is non-association node to UE.

The control method Signalling exchange figure of the synchronous context that Fig. 4 provides for third embodiment of the invention.Present embodiment hypothesis: UE is through 2G/3G network insertion association node, and UE initiates the access process of this association node again through the LTE network afterwards.As shown in Figure 4, present embodiment comprises:

Step 41, UE partly send TAU request (TAU Request) via the MME of eNB in association node (Combo MME/SGSN).

UE can distribute a temporary mark in order to identification UE for UE with the corresponding core net node part of network when certain network registry.For example: UE when the 2G/3G network registry, the packet TMSI that the SGSN of association node partly distributes for UE (Packet Temporary UniqueTemporary Identity is called for short P-TMSI); UE is when the LTE network registry, and the MME of association node partly distributes global unique temporary identity (Globally Unique Temporary Identity is called for short GUTI) for UE.When UE access 2G/3G next time or LTE network, can use SGSN part or MME part to identify oneself as the temporary mark that UE distributes.

In this step; UE moves to the registration area of LTE network from the registration area of 2G/3G network; UE partly initiates the TAU request to the MME of association node, and the SGSN that in the TAU request, carries association node partly is the P-TMSI of UE distribution, obtains the context of UE according to P-TMSI for the MME part.

The MME part of step 43, association node is partly obtained the context of UE to the SGSN of association node according to P-TMSI.

Because MME part and SGSN partly form association node, therefore, contextual the obtaining of UE can be realized through the internal interface between MME part and the SGSN part.

The MME part of present embodiment association node is confirmed as UE and between 2G/3G network and LTE network, is activated ISR in obtaining the contextual process of UE.

The MME of step 45, association node partly obtains after the up-to-date context of UE, initiates bearer update request (Update Bearer Request) to S-GW.

Step 47, S-GW send to P-GW with bearer update request (Update Bearer Request).

Step 49, P-GW are that UE upgrades the carrying in the LTE network, and send bearer update response (Update Bearer Response) to S-GW.

Step 411, S-GW send to bearer update response (Update Bearer Response) the MME part of association node.

The MME part of step 413, association node is sent TAU via eNB to UE and is accepted (TAU Accept) message; Accept to carry in the message announcement information and the node attribute information that ISR activates at TAU, it is association node that this node attribute information is used to notify the attribute of the network side node of the current access of UE.Node attribute information is an association node in order to the network side node of the current access of notice UE; And the announcement information that ISR activates activates in order to the ISR function of notice UE between 2G/3G network and LTE network.

The GUTI that portability association node MME partly distributes for UE in the announcement information that ISR activates; And (the Tracking Area Identification List of the tracking area identification list in the LTE network; The timer that periodically updates that abbreviation TAI List), also can comprise the LTE network side.

Through above-mentioned steps, association node has activated UE signaling reduction function (ISR) under 2G/3G network and the internetwork idle condition of LTE, and the attribute of the network side node of notice UE activation ISR is an association node.

Step 415, UE carry out 2G/3G network and the contextual triggering control of LTE inter-network synchronization according to node attribute information.

UE accepts message according to the TAU that receives, and can know that the network side node of the current activation of UE ISR is an association node.Under this situation; Even UE takes place to carry when changing (as: bearer update or newly-built carrying) and the registration area from this network mobile to another network at network, UE does not need to initiate once more the location area updating flow process yet, and to come the trigger network side to carry out UE contextual synchronously.

In application scenarios shown in Figure 3, UE is registered to an access network (as: 2G/3G network or LTE network), and afterwards, UE moves to another access network and is registered to this access network again; If hope UE saving signaling expense between these two networks this moment, then can initiate the activation of ISR, promptly UE is registered to the network of two kinds of RAT simultaneously.After UE activated ISR, UE moved in the corresponding registration area (RA or TA) of these two networks and need not initiate any registration process.When UE changes RA or TA (RA after moving or TA be not in the lane place of UE registration) will initiate common RAU or TAU process.Two kinds of connecting systems (MME of the SGSN of 2G/3G or LTE network) that UE is registered to all have the context (context) of UE.Usually when UE activates ISR; UE is last can to keep temporary mark (the Temporary Identity Used in Next Update that a next update uses; Abbreviation TIN) state; Initiate the location area updating flow process during in order to triggering UE position change next time, indicate the network node of the current access of UE to obtain the up-to-date context of UE, thereby realize that network side UE is contextual synchronous to other network elements through the location area updating flow process.

For UE after activating ISR; Even when change takes place to carry and moves to the registration area of another network in a network; Can the trigger position district yet new technological process more; Thereby reduce the required signaling consumption of synchronous UE context, on concrete the realization, can work as UE when a network takes place to carry change, the value that UE goes up the TIN parameter is set to " RAT-related TMSI ".

Illustrate: suppose that UE has activated ISR; And in the LTE network, take place to carry to change; It is the GUTI that UE distributes that TIN in the prior art on the UE is set to the LTE network, like this, when UE when the registration area of LTE network moves to the registration area of 2G/3G network; UE compares the RAT information of current access network and the value of the current TIN parameter of UE; Find that the value (GUTI) of TIN parameter and the RAT information (2G/3G) of the current access network of UE do not match, and then can initiate position updating request to SGSN, and in position updating request, carry GUTI; Obtain UE up-to-date context according to GUTI to MME for SGSN, thereby guarantee that the UE context in the UE context and MME is synchronous among the SGSN.

What be different from prior art is, present embodiment UE is after knowing that the network side node that activates ISR is association node, even UE carrying in one network changes, still the UE value that goes up the TIN parameter is set to " RAT-related TMSI ".After so being provided with; If take place to carry change in the LTE network and move to the registration area of 2G/3G network from the registration area of LET network; UE thinks that all the time the RAT information (2G/3G) of value (RAT-related TMSI) and the current access network of UE of TIN parameter matees; Therefore, can not initiate position updating request to SGSN.

The node that activates ISR owing to present embodiment is an association node, if UE has carried out the modification or the newly-built operation of carrying in the SGSN of association node part, the SGSN part is with the MME part of synchronous this information of automatic time to association node so; In like manner; If UE has carried out the modification or the newly-built operation of carrying in the MME of association node part; The MME part is with the SGSN part of synchronous this information of automatic time to association node so; Therefore, even UE takes place to carry change at certain network after activating ISR, when move to the registration area of another network next time, need not initiate the location area updating flow process and can realize that UE is contextual synchronously in real time between association node yet; Thereby practiced thrift the signaling consumption between association node and the UE, thereby helped the interface-free resources of the system of practicing thrift.

On the basis of present embodiment technical scheme; In the step 413, the MME of association node part is via in the announcement information that the ISR that UE transmission TAU accepts to carry in (TAU Accept) message activates, going back two RAT information of portability by eNB: the 2nd RAT information (being the second wireless access information of second network in the embodiment of the invention) of RAT information of 2G/3G network (being the first wireless access information of first network in the embodiment of the invention) and LTE network.Wherein a RAT information can comprise: the P-TMSI that association node SGSN partly distributes for UE; And (the Routing Area Identification of the Routing Area Identifier in the 2G/3G network; Be called for short RAI) (being the primary importance district sign of the embodiment of the invention), what also can comprise the 2G/3G network side periodically updates timer (being the period 1 property renewal timer of the embodiment of the invention).The 2nd RAT information can comprise: the GUTI (being second temporary mark of the embodiment of the invention) that association node MME partly distributes for UE; And (the Tracking Area Identification List of the tracking area identification list in the LTE network; Be called for short TAI List) (being the second place district sign of the embodiment of the invention), what also can comprise the LTE network side periodically updates timer (being the property second round renewal timer of the embodiment of the invention).Because the network side node of the current access of UE is the association node of 2G/3G network and LTE network, therefore, the 2G/3G network side periodically update periodically updating timer and can being the same timer that periodically updates of timer and LTE network side.Under this situation, association node can send to UE to the RAT information of two networks through a piece of news, helps further practicing thrift the signaling consumption between association node and the UE, thus the interface-free resources of the system of saving.

Technique scheme is to have passed through 2G/3G network insertion association node with UE, and UE is that example describes through LTE network initiation TAU flow process activation ISR again afterwards.In addition, if UE inserts association node through network LTE, UE initiates the RAU flow process through the 2G/3G network again and activates ISR afterwards, also can practice thrift the signaling consumption between association node and the UE, and its concrete implementation is similar with technique scheme, repeats no more.

The control method Signalling exchange figure of the synchronous context that Fig. 5 provides for fourth embodiment of the invention.Present embodiment and difference embodiment illustrated in fig. 4 are that present embodiment is in the attachment flow of the LTE network that UE initiates, and the network side node of knowing the current access of UE is an association node.The present embodiment hypothesis: UE partly initiates attachment flow to the MME of association node.As shown in Figure 5, present embodiment comprises:

Step 51, UE partly send attach request (Attach Request) to the MME of association node.
