Fast development along with telecommunication technology and association area thereof; Mobile communication has experienced 2G (GPRS (GPRS; General Packet Radio Service)) to 3G (conventional wireless communication systems (UMTS; Universal Mobile Telecommunication System)) differentiation also will further evolve to Long Term Evolution LTE (grouping system of evolution (EPS, EvolvedPacket System)) on this basis.
As subscriber equipment (UE; User Equipment) after registration on the network; Positional information (Routing Area RA with record self place; Routing Area), write down the packet domain Temporary Mobile Station Identity (P-TMSI, Packet Temporary Mobile Station Identity) of network simultaneously for its distribution.Under the general situation, UE is in holding state, does not carry out data service, does not set up real signaling between UE and the network and is connected with data, and we are referred to as UE and are in the IDLE attitude.When variation has taken place in the position of UE; Such as: moved to another RA from a RA; For the UE relevant information that is write down in the network that upgrades in time, this moment, UE sent the Routing Area Update request message to relevant network node, for example sent to Serving GPRS Support Node (SGSN; Serving GPRS Support Node), carry out the Routing Area Update flow process.At this moment, because the change of UE position, the old side SGSN before moving possibly no longer be suitable for service UE; To select new side SGSN is the UE service; New side SGSN will obtain said UE related context from old side SGSN, comprise mobile management (MM, Mobility Management) and packet data protocol session (PDP; Packet Data Protocol) context possibly distribute new P-TMSI for UE simultaneously again.Receive after Routing Area Update accepts message RAU Accept, UE will preserve new P-TMSI and current place RA sign (RAI).In addition, because change has taken place SGSN, new side SGSN needs more new technological process (Update Location) of executing location.The change that to write down SGSN as the attaching position register (HLR, Home Location Register) of record UE CAMEL-Subscription-Information in the network, and executing location cancellation flow process (Cancel Location) are cancelled old side SGSN and are gone up the information that UE registers.

This a large amount of invalid routing update signaling traffic load that causes because of frequent district reselecting; Quantity is 5~6 times of other RAU; Increased network load greatly, can cause very big impact, also must affect user experience simultaneously the management equipment in the mobile communications network.
For solving different radio access technologies (RAT; Radio Access Technology) invalid RAU Signalling exchange between; The solution that prior art proposes is: under the LTE network; All possess under signaling reduction under the Idle state (ISR, Idle-mode Signaling Reduction) the ability situation at terminal and network equipment, consult to activate ISR by terminal and network equipment.
There is following shortcoming at least in prior art:
Activate the process need terminal of ISR and participate in, however present most of terminal, and for example existing G/U network (GPRS and UMTS) terminal does not have the ability of consulting to activate ISR, so the scheme of prior art can't be applied to existing G/U network.

The embodiment of the invention provides a kind of signaling reduction method, to be example shown in Fig. 1, comprises the steps:
Step 10: the second signaling reduction network equipment in secondary route district receives the Routing Area Update request that UE sends;
Step 11: if the said second signaling reduction network equipment and UE initiate the preceding first via of this Routing Area Update by between the first signaling reduction network equipment of distinguishing not being said UE activation SR; The then said second signaling reduction network equipment and the said first signaling reduction network equipment are consulted to activate ISR for said UE; And after confirming as said UE activation ISR, it is that said UE has activated ISR that the said second signaling reduction network equipment of informing network depositing equipment and said first is practiced thrift the network equipment;
The network formats that said secondary route district supports is different from the network formats that the said first via is supported by the district.
The said second signaling reduction network equipment and the said first signaling reduction network equipment are consulted to comprise for said UE activates ISR:
The said second signaling reduction network equipment sends context request message and gives the said first signaling reduction network equipment, and the MM and the PDP Context of asking said UE carry first and support the ISR sign in the said context request message; The said second signaling reduction network equipment receives the context response information that the said first signaling reduction network equipment sends, and carries MM and the PDP Context of said UE in the said context response information and carries the second support ISR sign.
First support the value of ISR sign whether to represent requesting activation ISR through what carry in the said context request message, and second support the value of ISR sign representes whether allow to activate ISR through what carry in the said context response information.Value as if the first support ISR sign of carrying in the said context request message is the value of expression requesting activation ISR, and the value that the second support ISR that carries in the said context response information identifies is for representing to allow the value of activation ISR; The then said second signaling reduction network equipment and said first is practiced thrift the network equipment and is confirmed as said UE and activate ISR, in the said second signaling reduction network equipment and the said first signaling reduction network equipment, preserves MM and the PDP Context of said UE and is the information of UE activation ISR.Value as if the first support ISR sign of carrying in the said context request message is the value of expression requesting activation ISR, and the value that the second support ISR that carries in the said context response information identifies is for representing not allow to activate the value of ISR; The then said second signaling reduction network equipment and said first is practiced thrift the network equipment and is consulted to confirm not to be that said UE activates ISR; Or the value of the first support ISR sign of carrying in the said context request message is to represent the not value of requesting activation ISR, and the value of the second support ISR sign of carrying in the said context response information is for representing not allow to activate the value of ISR; The then said second signaling reduction network equipment and said first is practiced thrift the network equipment and is consulted to confirm not to be that said UE activates ISR.

Said secondary route district supports the GPRS network standard, and the said first via is supported the UTMS network formats by the district, and just the first via before the Routing Area Update is different by the network formats of the secondary route district support behind district and the Routing Area Update.
If be not that said UE activates ISR, then execution in step 22; If activated ISR for said UE, then execution in step 23;
Step 22: the 2nd SGSN and a said SGSN consult to activate ISR for said UE; And after consulting to confirm as said UE activation ISR; Notice HLR writes down the information that said UE registers and is recorded as the information that UE activates ISR on a SGSN and said the 2nd SGSN, execution in step 23 afterwards;
Said the 2nd SGSN and a said SGSN consult to comprise for the process of said UE activation ISR:
Said the 2nd SGSN sends the SGSN context request message and gives a said SGSN; Ask MM and the PDP Context of said UE; Carry first in the said SGSN context request message and support the ISR sign, and the value of this first support ISR sign is the value of predetermined expression requesting activation ISR; For the old SGSN that does not upgrade with existing network compatible; In the SGSN context request message that said the 2nd SGSN sends, increase by one and support the ISR sign; Like ISR_Supported; If do not carry this first support ISR sign in the SGSN context request message, represent that then said the 2nd SGSN does not possess the ISR ability, does not consult to activate ISR; Support the ISR sign if carry first in the SGSN context request message, and should support the value of ISR sign value for predetermined expression requesting activation ISR, for example value is 1, representes that then said the 2nd SGSN possesses the ISR ability, consults to activate ISR; Support the ISR sign if carry in the SGSN context request message, and this first supports ISR sign value to be the predetermined expression value of requesting activation ISR not, for example value is 0, representes that then SGSN possesses the ISR ability, does not consult to activate ISR;
Said the 2nd SGSN receives the SGSN context response information that a said SGSN sends; Carry MM and the PDP Context of said UE in the said SGSN context response information and carry second and support ISR sign and value can activate the value of ISR for predetermined expression, for example value is 1;
The information of in said the 2nd SGSN and a said SGSN, preserving MM and the PDP Context of said UE simultaneously and activating ISR for UE;
Said the 2nd SGSN sends the location update request message of carrying ISR activation sign and gives HLR; Make said HLR confirm as said UE and activated ISR according to this ISR activation sign; Writing down information and the information that is recorded as UE activation ISR, no longer the route district of an execution and the said SGSN cancellation flow process that said UE registers on the said HLR on a SGSN and said the 2nd SGSN.
Carry through whether and to support the ISR sign to guarantee the compatibility with the existing network network element in SGSN context request message or SGSN context response information; Consult to activate to carry in the ISR process and support the ISR sign; For discerning this support ISR sign but because the other reasons refusal activates the equipment (the not old network equipment of upgrading) that ISR perhaps not discerns this sign; ISR will can not set up owing to consulting failure, not receive whether to have the restriction of ISR ability between the network element in the intercommunication.
Step 23: said the 2nd SGSN replys Routing Area Update and accepts message to said UE;
The described signaling reduction method of the embodiment of the invention is that UE activates ISR by consulting between the SGSN; And consulting successfully back notice HLR; This process only need be revised the signaling process of network side, need not make any modification to a large amount of 2G/3G terminal of existing network, and not rely on the shuffling sub-district; Do not require that SGSN supports 2G and 3G simultaneously, has effectively reduced the network side signaling traffic load yet.
For further understanding the present invention, the example that has particular application as with embodiment of the invention signaling reduction method is elaborated below.
RAT1 and RAT2 represent two kinds of network formats respectively in the following instance, and for example RAT1 is the GPRS of 2G, and RAT2 is the UTMS of 3G; In addition, the SGSN1 of RAT1 refers to that this SGSN1 supports RAT1, whether does not support RAT2 but do not limit SGSN1, and promptly whether the embodiment of the invention does not limit SGSN and support 2G and 3G to build jointly, and in like manner the SGSN2 of RAT2 representes SGSN2 support RAT2.As shown in Figure 3, the described signaling reduction flow process of this instance comprises the steps:
The SGSN2 that step 30:UE is moved to RAT2 from the SGSN1 of RAT1 sends Routing Area Update request message RAU Request to SGSN2;
On the SGSN1 attached to RAT1 before the UE migration, behind the SGSN2 of moving to RAT2, need to initiate the RAU flow process.It is understandable that the situation of initiating RAU here is not limited to UE and moves, and also can comprise the situation that other need initiate RAU.
Step 31: network equipment is consulted to this UE activates ISR, and after consulting to confirm as said UE activation ISR, notifies said SGSN2 of HLR and SGSN1 to activate ISR for said UE;
Network equipment is consulted to activate ISR and notify the detailed process of HLR to comprise following substep for this UE:
Step 310:SGSN2 sends message SGSN Context Request to SGSN1, the MM of the said UE of acquisition request and PDP Context;
Can carry the ISR_Supported cell among the said SGSN Context Request, if carry this ISR_Supported cell, and ISR_Supported cell value is 1, and expression SGSN2 possesses ISR ability, requesting activation ISR; If carry this ISR_Supported cell, and ISR_Supported cell value is 0, representes that then SGSN2 possesses the ISR ability, this time flow process requesting activation ISR not; When not carrying this cell, expression SGSN2 does not possess the ISR ability, can not activate ISR; The implication that ISR_Supported cell value described herein is 1 or 0 representative is merely an embodiment of the present invention, and concrete value is not limited thereto in the practical operation.
Step 311:SGSN2 receives the SGSN Context Response message that SGSN1 replys, and comprises MM and the PDP Context of said UE in the SGSNContext Response message;
Said SGSN Context Response message can be carried the ISR_Supported cell, and when not carrying this ISR_Supported cell, expression SGSN1 does not possess the ISR ability, can not activate ISR; If carry this ISR_Supported cell, and ISR_Supported cell value is 1, representes that then SGSN1 possesses the ISR ability, and negotiation can be set up ISR; If carry this cell, and ISR_Supported cell value is 0, and expression SGSN1 possesses the ISR ability, and this time flow process is not set up ISR.The implication that ISR_Supported cell value described herein is 1 or 0 representative is merely an embodiment of the present invention, and concrete value is not limited thereto in the practical operation.
All remain with MM and the PDP Context of said UE this moment on SGSN2 and SGSN1, and write down for this reason that UE has activated ISR.
Step 312:SGSN2 sends Update Location message to HLR, will carry ISR in the said Update Location message and activate sign ISR_Activated;
Step 313:HLR detects in the said Update Location message and carries ISR_Activated; Then HLR does not implement the Cancel Location flow process of SGSN1; Writing down the information that said UE registers on this HLR on SGSN1 and SGSN2; And write down for this UE has activated ISR, and reply Update Location ACK to said SGSN2;
Be outstanding the present invention, omitted steps such as inserting user data between HLR and the SGSN2 among the figure.
After said SGSN2 receives said Routing Area Update request; Can distribute P-TMSI and RAI for said UE; To be called P-TMSI2 and RAI2 by P-TMSI and the RAI that SGSN2 distributes in the present embodiment; Be after said UE activates ISR, said SGSN2 will give SGSN1 synchronously for P-TMSI2 and the RAI2 that said UE distributes, and on SGSN1 and SGSN2, can preserve the corresponding relation of P-TMSI+RAI and user index.
Step 32:SGSN2 replys Routing Area Update and accepts message RAU Accept to UE, carries P-TMSI2+RAI2 in the RAUAccept message, accomplishes this RAU flow process.
Following situation might take place at SGSN1 and SGSN2 after said UE activates ISR in the embodiment of the invention, and following several kinds of situation do not have the sequencing restriction:
1) UE initiates the RAU flow process from the SGSN1 that the SGSN2 of RAT2 moves back RAT1;
After UE moves back the SGSN1 of RAT1 from the SGSN2 of RAT2; It is inconsistent that UE detects the route district at RAI2 and current place of self storage; Then UE initiatively initiates the routing area updating RAU flow process; Promptly send Routing Area Update request RAU Request to network side, the SGSN1 of network side locatees concrete UE according to the P-TMSI+RAI of storage and the corresponding relation of user index, has activated ISR when detecting for this UE; Explain that then SGSN1 inside preserves MM and the PDP Context of this UE; And HLR is last to have write down the information that UE registers on SGSN1 and SGSN 2, then do not need to obtain relevant information to SGSN2, also will not initiate the flow process to the Update of HLR Location; Accept message RAU Accept but directly reply Routing Area Update, carry in the RAU Accept message that SGSN1 is the P-TMSI1+RAI1 that said UE distributes in this RAU flow process) to UE.
In this process owing to activated ISR for UE; Therefore saved between the network side SGSN and the signaling between SGSN and the HLR; Just SGSN1 has activated under the situation of ISR for UE recognizing, need not to carry out the operation of obtaining MM and the PDP Context of said UE to SGSN2, has saved the signaling of obtaining MM and PDP Context process; And need not to initiate more new technological process of position to HLR, saved the more signaling of new technological process of position.
2) UE changes at the PDP Context of SGSN2 or SGSN1;
When UE at a side RAT network, after for example the SGSN2 of RAT2 has changed relevant PDP Context, set up between the network of ISR mechanism, for example active synchronization PDP Context not between SGSN2 and the SGSN1; Can select deexcitation ISR, after perhaps waiting until UE for example RAT1 initiating RAU from opposite side RAT network (not changing that side RAT network of PDP Context), carry out again PDP Context synchronously.Can avoid change like this, and all go in real time synchronously the context synchronous signaling expense that is increased at every turn to the both sides network of setting up ISR mechanism owing to PDP Context.
3) after ISR activates, carry out user's separation process;
After ISR activated, HLR initiated user's separation process, and the HLR notice promptly notifies SGSN1 and SGSN2 to carry out user's separation process respectively for the both sides SGSN that UE has activated ISR; If UE is connected state under this SGSN2, then SGSN2 need notify opposite end SGSN (for example SGSN1) the local resource that discharges, and need not wait for UE mutual; If SGSN is in Idle state to UE in both sides at this moment; Then both sides SGSN is that SGSN1 and SGSN2 carry out the paging flow process respectively, initiates paging to said UE, receives the SGSN (for example SGSN1) of UE page response; Notice opposite side SGSN (for example SGSN2); Stop paging, and require the local resource that discharges of its (SGSN2), need not wait for mutual with UE;
4) after UE gets into the IDLE attitude, there is downlink data need be transferred to said UE;
After UE got into the IDLE attitude, when having downlink data to be transferred to UE as if GGSN, downlink data can be buffered in earlier on the SGSN that receives this downlink data, for example SGSN2; This SGSN2 is found to be this UE and has activated ISR mechanism, and UE is in Idle state, need other end SGSN1 that notice activates ISR with this side SGSN2 to the UE distributing paging; After any side SGSN receives the page response of UE, all will notify opposite side SGSN to stop paging; If the SGSN2 of buffer memory downlink data receives the page response of UE, then rebuild and eat dishes without rice or wine to connect, recover end to end data transmission tunnel and carry out transfer of data; If opposite side SGSN (like SGSN1) receives the page response of said UE; Then need be on the PDP Context of synchronous said UE between SGSN1 and the SGSN2 and SGSN2 data in buffer; Set up the data forwarding tunnel between SGSN1 and the GGSN; And the connection of eating dishes without rice or wine of setting up SGSN1, carry out transfer of data again;
5) between the SGSN2 of the SGSN1 of RAT1 and RAT2 for after UE activates ISR, UE moves to the SGSN3 of RAT2 from the SGSN2 of RAT2, perhaps UE moves to the SGSN4 of RAT1 from the SGSN1 of RAT1;
As UE owing to move once more, after having changed SGSN under the same RAT, with the ISR between the SGSN2 of the SGSN1 of deexcitation RAT1 and RAT2;
Concrete deactivating operation can comprise: if UE moves to the SGSN3 of RAT2 from the SGSN2 of RAT2, then can notify SGSN1 deexcitation ISR by SGSN2, SGSN1 deletes said UE corresponding MM and PDP Context; Perhaps, if UE moves to the SGSN4 of RAT1 from the SGSN1 of RAT1, then can notify SGSN2 deexcitation ISR by SGSN1, SGSN2 deletes said UE corresponding MM and PDP Context.
6) between the SGSN2 of the SGSN1 of RAT1 and RAT2 for after UE activates ISR, UE moves to the SGSN3 of RAT1 from the SGSN2 of RAT2, perhaps UE moves to the SGSN4 of RAT2 from the SGSN1 of RAT1;
As UE owing to move once more, after having changed SGSN under the different RAT, with the ISR between the SGSN2 of the SGSN1 of deexcitation RAT1 and RAT2; Simultaneously, can be between the SGSN3 of the SGSN2 of RAT2 and RAT1 according to actual conditions (if SGSN3 or SGSN4 have the ISR ability), or consult once more between the SGSN4 of the SGSN1 of RAT1 and RAT2 to activate ISR for said UE.
