Embodiment
Inventor notices realizing in process of the present invention:
One, the CAMEL-Subscription-Information of current LIPA comprises:
(1) APN information, APN is divided into LIPA-conditional(and can and normally accesses for LIPA access), LIPA-prohibited(forbids LIPA access), or LIPA-only(can only be used for LIPA access);
(2) CSG information, in the CSG of UE subscription data, supports each CSG of LIPA all will carry the APN of corresponding LIPA-only or LIPA-conditional;
(3) in roaming scence, the VPLMN(Visited Public Land Mobile Network of all permission LIPA access, visit public land mobile network) to carry LIPA Allowed(permission) mark.
If need to initiating LIPA PDN, two UE connect, the APN that UE uses need to be the LIPA-conditional that occurs in UE CAMEL-Subscription-Information or the APN of LIPA-only, and the current residing CSG of UE occurs, and allows UE to use current APN to carry out LIPA access in the CSG of UE CAMEL-Subscription-Information.
In addition,, under roaming scence, in the CAMEL-Subscription-Information of UE, also needing has the VPLMN LIPA Allowed mark for this PLMN, now just allows UE to set up LIPA PDN and connects.
Three, for the APN of LIPA conditional, when UE specific CSG community initiate for this APN(according to CAMEL-Subscription-Information) PDN(Packet Data Network, packet data network) connect to set up and ask, and while carrying LGW address in Home eNodeB, network side thinks that this PDN is connected to LIPA PDN and connects;
When UE initiates to connect for the PDN of this APN the request of foundation at other community (as macrocell), or network side is not from RAN(Radio Access Network, wireless access network) side (being Home eNodeB) is while receiving LGW address, network side thinks that it is not that LIPA PDN connects that this PDN connects.
Four,, in APN jamming control method, keep out of the way timer and stop UE to initiate SM request by issuing SM.In this mechanism, if network side judges the APN that UE asks and occurs congested, send about the congested cause value of APN and keep out of the way timer for the SM of this APN to UE, afterwards, when receiving this SM, keeps out of the way after timer UE, start this SM and keep out of the way timer, and before this SM keeps out of the way timer expiry, can not initiate any request of the SM for this congested APN (as PDN connects the request of foundation).
Further, network side also can be preserved for the SM of this APN and keep out of the way timer, and it is per UE per APN storage that this SM keeps out of the way timer, and this SM keeps out of the way timer for refusing the follow-up request of the SM for this APN.
Five, for the APN of LIPA conditional, existence is set up LIPA PDN connection and is connected two kinds of situations with non-LIPA PDN, even if UE stays out in the base station range of front yard, network side also can allow UE to be established to PGW(Packet Data Gateway, packet data gateway) non-LIPA PDN connect.
Therefore,, in the time judging that LIPA conditional APN is congested, may not occur that the non-LIPA PDN that is established to PGW connects.In the time that whether network side is congested according to the APN of existing rule judgment UE request, existing rule is also not suitable for LIPA-conditional APN.
Six, be the shunting to core network load because UE is linked into local network, for the connection that is established to local network, network should not use APN congestion control mechanism.Therefore occur when congested, should not stop UE to be linked into local network at LIPA conditional APN.
In prior art, after the PDN that UE initiates to be established to LIPA conditional APN at macrocell connects and refused, can start the SM back-off timer of corresponding this APN; UE moves to particular home network afterwards, wishes to initiate LIPA and connects while setting up request, due to the now operation of SM back-off timer, causes UE can not initiate LIPA and connects the request of foundation, thereby make UE can not access local network.
For the problems referred to above of prior art, the embodiment of the present invention provides a kind of LIPA establishment of connection method and apparatus, for LIPA establishment of connection process, do not carry out congestion control, make subscriber equipment in the SM of APN back-off timer run duration, also can set up for the LIPA of this APN and connect, guarantee the normal foundation that LIPA connects.
Below in conjunction with the accompanying drawing in the present invention, the technical scheme in the present invention is clearly and completely described, obviously, described embodiment is only a part of embodiment of the present invention, rather than whole embodiment.Based on the embodiment in the present invention, those of ordinary skills, not making the every other embodiment obtaining under creative work prerequisite, belong to the scope of protection of the invention.
Embodiment mono-
The embodiment of the present invention one provides a kind of LIPA PDN establishment of connection method, is the processing mode for LIPA conditional APN, and as shown in Figure 2, the method comprises the following steps:
It should be noted that, when UE moves to behind CSG community, the LIPA PDN that can support the appointment APN connecting for LIPA PDN to initiate by network side JiangCSG community (CSG community 1) connects the information (APN1) of setting up and notifies to UE, afterwards, UE can be known in APN1 CSG community 1 and connects for LIPA PDN.
In addition, can also be on UE (in the SIM card of UE) configuration pin Dui Ge CSG community, for initiating the information of the appointment APN that LIPA PDN connects, based on the information of this configuration, when UE moves to behind CSG community 1, UE can be known in APN1 CSG community 1 and connects for LIPA PDN.
Step 202, UE sends for the PDN that specifies APN and connects the request of foundation to network side, connects to set up LIPA PDN.Wherein, this PDN connection is set up request for the PDN connection foundation request for LIPA conditional APN.
Concrete, when UE determine self need to initiate for specify APN LIPA PDN connect time, if started on UE for the session management of this appointment APN and kept out of the way timer back-off timer, UE stops or removing this session management back-off timer, and sends for the PDN that specifies APN and connect the request of foundation to network side.
For example, when starting, APN1 has session management back-off timer, in QieCSG community 1, APN1 connects for LIPA PDN, therefore, when UE moves to CSG community 1, and need to send PDN for APN1 and connect and set up when request, UE stops or removing this session management back-off timer, and sends for the PDN of APN1 and connect the request of foundation to network side.
APN jamming control method based on current, network side can know that whether certain APN is in congestion state, in the time judging that whether LIPA Conditional APN is congested, only for judging with the PGW in the core net that non-LIPA PDN connects and this APN is corresponding of this APN in core net, in this process embodiment of the present invention, repeat no longer in detail, take specify APN in congestion state as example.
Determine that at network side PDN is connected in the process that LIPA PDN connects or non-LIPA PDN connects, CSG community, subscriber equipment place and appointment APN described in when network side can connect foundation request by the CAMEL-Subscription-Information of UE, transmission PDN, determine that PDN is connected to LIPA PDN connection or non-LIPA PDN connects.
Concrete, if in the CAMEL-Subscription-Information of UE, CSG community allows to use specifies APN to set up LIPA PDN connection, network side determines that PDN is connected to LIPA PDN and connects; For example, in the CAMEL-Subscription-Information of UE, CSG community 1 allows to use APN1 to set up LIPA PDN connection, and network side determines that PDN is connected to LIPA PDN and connects.Otherwise network side determines that PDN is connected to non-LIPA PDN and connects.
Further, determine that at network side PDN is connected in the process that LIPA PDN connects or non-LIPA PDN connects, when meeting after the corresponding strategies of above-mentioned CAMEL-Subscription-Information, if network side determines that Home eNodeB sends in the specify message of network side and carried LGW address, network side determines that PDN is connected to LIPA PDN and connects; Otherwise network side determines that PDN is connected to non-LIPA PDN and connects.
This Home eNodeB sends to the specify message of network side to include but not limited to: initial UE message(initial UE information) the up Non-Access Stratum transmission of message, UPLINK NAS TRANSPORT(, only for E-UTRAN system) message, initial the direct transferring of UTRAN Originated DIRECT TRANSFER(, only for UTRAN system) message etc.
After this step, if being connected to LIPA PDN, PDN connects execution step 205; If being connected to non-LIPA PDN, PDN connects execution step 206.
In sum, in the embodiment of the present invention, for LIPA conditional APN, judge this APN occur congested after, connect for the PDN from UE the request of foundation, need to distinguish that this PDN is connected to that LIPA PDN connects or connect for non-LIPA PDN.Connect for the PDN connecting for LIPA PDN the request of foundation, do not need to carry out congestion control (being the congestion control of SM); For being that the PDN that non-LIPA PDN connects connects the request of foundation, need to carry out congestion control.
Concrete, when network side has started the congestion control for LIPA conditional APN, and in network side storing after the session management back-off timer of per UE per APN, network side is received while connecting foundation request for the PDN of this APN again, find in the CAMEL-Subscription-Information of UE, GaiCSG community allows to use this APN to carry out LIPA PDN connection and sets up.
Afterwards, network side need to check that Home eNodeB sends to MME(Mobility Management Entity, Mobility Management Entity) initial UE message or UPLINK NAS TRANSPORT message in whether carried LGW address, or check that Home eNodeB sends to SGSN(Serving GPRS Supporting Node, Serving GPRS Support Node) initial UE message or UTRAN Originated DIRECT TRANSFER message in whether carried LGW address, if carried LGW address, network side can not be refused because APN is congested this PDN connection and set up request, this PDN connects the request of foundation and does not need to carry out congestion control.
In the embodiment of the present invention, network side allow this UE set up LIPA PDN connect after, when network side receives after the session management request for appointment APN from UE, if session management request is for connecting and send based on LIPA PDN, network side is determined and this session management request is not carried out to congestion control.This session management request includes but not limited to: PDN connects the request of foundation, and bearing modification request and dedicated bearer are set up request.
Concrete, when network side is received after other SM signaling request for LIPA conditional APN of UE, if find in the CAMEL-Subscription-Information of UE, CSG community allows to use this APN to carry out LIPA PDN connection and sets up, and find to have comprised LGW address in Initial UE message or UPLINK NAS TRANSPORT or UTRAN Originated DIRECT TRANSFER message, this SM signaling request is not used to APN congestion control.
It should be noted that, in the embodiment of the present invention, network side, judging in the whether congested process of APN, is only considered the information that uses the non-LIPA PDN of this APN foundation to connect.For example, the LIPA PDN setting up for this APN of above-mentioned use connects, and in the time judging that whether APN is congested, does not add up the relevant information that this LIPA PDN connects.
Embodiment bis-
The embodiment of the present invention two provides a kind of LIPA PDN establishment of connection method, is the processing mode for LIPA conditional APN, and as shown in Figure 3, the method comprises the following steps:
Step 301 is configured to lower strategy on MME.
(1) in the time judging that whether LIPA Conditional APN is congested, only for judging with the PGW in the core net that non-LIPA PDN connects and this APN is corresponding of this APN in core net.
(2) connect for the LIPA PDN that uses this APN to be linked into local network, network side does not carry out APN congestion control.
Step 302, UE uses LIPA conditional APN to send PDN connection and sets up request on macrocell.
Step 303, MME refuses this PDN and connects the request of foundation, and issues SM back-off timer in refuse information is set up in PDN connection.
Step 304, UE starts SM back-off timer, moves to afterwards home network and covers CSG community.
Step 305, UE wishes to send and uses the LIPA PDN of LIPA conditional APN to connect the request of foundation, stops or removing the corresponding SM back-off of this APN timer.
Step 306, UE uses LIPA conditional APN to send PDN connection to Home eNodeB (HeNB) and sets up request.
Step 307, HeNB connects in setting up the Initial UE message of request message or UPLINK NAS TRANSPORT message and carries LGW address carrying PDN.
Step 308, HeNB uses LIPA conditional APN to send PDN connection to MME and sets up request.
Step 309, MME judges UE place CSG according to CAMEL-Subscription-Information and allows to set up LIPA PDN connection with LIPA conditional APN, in concurrent present Initial UE message or UPLINK NAS TRANSPORT, carry LGW address, determine that afterwards this PDN is connected to LIPA PDN and connects, and this PDN connection request of setting up is not carried out to APN congestion control.
Step 310, completes LIPA PDN and connects process of establishing.
