LIPA PDN mobile management processing methods provided in an embodiment of the present invention, it is right that network side passes through LIPA PDN are ambulant to be supported, it is possible to achieve when user leaves the cell for setting up LIPA PDN, LIPA PDN connections can be kept, do not translated and put, ongoing LIPA business is not disrupted, and is met the actual demand of user, is improved QoS.
The procedure chart 3 of subscription data is obtained from HSS this embodiment describes MME and obtains subscription data schematic flow sheet for the embodiment of the present invention, as shown in figure 3, the flow, which is UE, adheres to (attach) flow, is specifically included：
Step 300, UE sends Attach Request message by eNB to MME, and eNB sets up message " Initial UE message " by S1 connections and forwards the message, and message includes UE the first access information；The first access information includes cell ID in the present embodiment（Cell ID), access network element mark, CSG ID, local gateway IP address（L-GW address) in any one or multiple combinations.First access information by eNB can also be reported to MME in SI setu Establishing process, or provided in other S1 connection building process and arrive MME, such as the S1 connections foundation in switching flow, " Service Request " flow.Local gateway IP address can be reported by eNB, or MME accesses cell or CSG or access network element ID in name server according to UE（Domain Name Server, DNS) middle inquiry acquisition.If user asks to set up LIPA PDN connections during attach, mobile management network element can record UE the first access information.Local gateway in the present embodiment（Local GW) refer to can for other IP devices of accessing local network Gateway GPRS Support Node（Gateway GPRS Support Node, GGSN) or PGW.
Step 301, MME and HSS interactions obtain subscription data；
MME sends position updating request to HSS（Update Location Request) message；Receive HSS after the message and send location updating confirmation (Update Location Ack) message to MME, the message includes the subscription data of user.
Acquired subscription data includes whether user LIPA PDN allow mobile information, for example, can be：
Whether mobile subscription data is allowed, i.e., it is the signing of user's granularity whether to allow mobile, and form is as follows：
{UE ID, LIPA Mobility permission...} ; Whether whether CSG signings allow mobile subscription data, for example, movement can be allowed to be stored in as a part for CSG subscription data in CSG subscription data：
{CSG ID, LIPA Mobility permission , ΑΡΝ1,ΑΡΝ2} ;
Whether Access Point Name APN allows mobile subscription data (APN granularities, refer in user's APN subscription data, if allow the instruction of movement)；
{ UE ID, (CSG subscription data）, (APNl, PDP type, LIPA Mobility permission), (APN2, LIPA Mobility permission) }；
Whether the APN accessed under CSG allows mobile subscription data (CSG/APN granularities, whether corresponding APN allows the instruction of movement in user's CSG subscription data), whether can for example allow movement to be stored in as a part for user's APN subscription data in APN subscription data：
{CSG ID, (APNl , LIPA Mobility permission), (APN2, LIPA Mobility permission) , } ;
The APN accessed under Access Point Name APN and CSG, the difference of the two is that the former is APN signing attribute, and the CSG of user's access not related, such as the APN of user allows movement, and no matter user accesses from which CSG, all allows movement；It is also CSG signing attribute, it is mobile relevant with user accesses CSG whether APN allows, such as user sets up PDN connections using APN1, when user accesses from CSG1, allows movement and the latter is not only APN signing attribute；And do not allow movement when being accessed from other CSG.
Whether it should be strongly noted that allowing mobile implication to be, when user accessing information changes, if allowing movement, LIPA PDN connections retain, the LIPA PDN connections that user can be continuing with having set up in former cell in target side；Otherwise LIPA PDN Connection Releases, the LIPA PDN connections that user can not be continuing with setting up in former cell in target side.
Step 302, MME sends message to eNB and sets up RAB.
If user establishes LIPA PDN connections during attach, MME retains user equipment access information.
UE can also set up LIPA PDN connections by the request of PDN connection building process.Fig. 4 is this Inventive embodiments PDN connection building process schematic diagrames, as shown in figure 4, this method includes：
Step 400, UE sends PDN connections to MME and sets up request message；
MME is preserving the first access information when UE sets up LIPA PDN after receiving message.Wherein,
UE the first access information acquisition methods may refer to above-described embodiment.
Step 401, MME sends RAB appointments/E-RAB assignment messages to eNB.
UE the first access information can be sent to MME in flow as shown in Figure 3 or Figure 4, and the PDN flows of setting up shown in Fig. 4 are carried out after the attachment flow shown in Fig. 3, because MME has got UE signing information from HSS in attachment flow, therefore MME may not necessarily will arrive the signing information that HSS obtains UE in Fig. 4 flows.
After UE the first access information is got according to above method embodiment, MME stores the-access information, and upon receipt in afterflow journey after UE the second access information, to the LIPA set up
Moving property of PDN is managed, and refers to following examples.
Fig. 5 is se ce request procedure schematic diagram of the embodiment of the present invention, and the present embodiment is mainly used in Service
During Request flows, MME processing after UE movements, as shown in figure 5, this method includes：
Step 500, the UE that there is LIPA PDN sends Service Request service requests by eNB to MME, and eNB reports UE the second access information；
Step 501, MME returns to E-RAB/RAB appointments/initial UE context to eNB and sets up message；Because MME saves the first access information when UE sets up LIPA PDN（Referring to Fig. 3, figure
4 corresponding embodiments), the first access information when MME sets up LIPA PDN according to UE the second access information and UE is compared, and combination UE subscription data is judged.If access information is inconsistent and subscription data does not allow LIPA PDN connections to move, MME assigns initial UE context to set up in E-RAB/RAB does not include the RAB information of LIPA PDN connections in message, such as carrying mark, QoS (Quality of Service, service quality) etc., otherwise include the RAB information of LIPA PDN connections.
There is one kind in following several possible combinations in the present embodiment MME concrete operations：
If MME knows UE access cell not according to the first access information and the judgement of the second access information Become, then notify access network element to set up the related carryings of LIPA PDN, be specially to set up message to access network element transmission RAB assignment messages or initial context, include LIPA PDN carrying information.
If MME judges to know the access cell change for meeting UE according to the first access information and the second access information, mobile subscription data whether is allowed to determine whether movement according to UE, if allowing, access network element is then notified to set up the related carryings of LIPA PDN, specially E-RAB assignment messages are sent to access network element or initial context sets up message, include LIPA PDN carrying information；If not allowing, send RAB assignment messages or initial context sets up message, do not include LIPA PDN carrying information, LIPA PDN connections are discharged later.
If MME judges to know the access cell change for meeting UE according to the first access information and the second access information, mobile subscription data whether is allowed to determine whether movement according to UE APN, if allowing, access network element is then notified to set up the related carryings of LIPA PDN, specially RAB assignment messages are sent to access network element or initial context sets up message, include LIPA PDN carrying information；If not allowing, send RAB assignment messages or initial context sets up message, do not include LIPA PDN carrying information, translate put LIPA PDN connections later.
If MME judges to know that the access CSG for meeting UE does not have change according to the first access information and the second access information, whether UE CSG signings allow mobile subscription data to determine whether movement, if allowing, access network element is then notified to set up the related carryings of LIPA PDN, specially RAB assignment messages are sent to access network element or initial context sets up message, include LIPA PDN carrying information；If not allowing, send RAB assignment messages or initial context sets up message, do not include LIPA PDN carrying information, translate put LIPA PDN connections later.
If the access informations of MME first and the second access information judge to know access cell change, CSG does not change, the subscription data whether APN accessed according to user equipment described above under CSG moves judges that LIPA PDN can be moved, access network element is then notified to set up the related carryings of LIPA PDN, specially RAB assignment messages are sent to access network element or initial context sets up message, include LIPA PDN carrying information；If not allowing, send RAB assignment messages or initial context sets up message, do not include LIPA PDN carrying information, LIPA PDN connections are discharged later. If MME judges to know that meeting UE accesses CSG does not have change according to the first access information and the second access information, the subscription data whether APN accessed under the CSG moves determines whether movement, if allowing, access network element is then notified to set up the related carryings of LIPA PDN, specially RAB assignment messages are sent to access network element or initial context sets up message, include LIPA PDN carrying information；If not allowing, send RAB assignment messages or initial context sets up message, do not include LIPA PDN carrying information, LIPA PDN connections are discharged later.
If MME judges to know that the local gateway IP address for meeting UE is constant according to the first access information and the second access information, if whether allowing mobile subscription data to judge to allow movement according to user LIPA PDN, access network element is then notified to set up the related carryings of LIPA PDN, specially send RAB assignment messages or initial context sets up message, include LIPA PDN carrying information；If not allowing, send RAB assignment messages or initial context sets up message, do not include LIPA PDN carrying information, translate put LIPA PDN connections later.
If MME judges to know that the local gateway IP address for meeting UE changes according to the first access information and the second access information, then send RAB assignment messages or initial context sets up message, do not include LIPA PDN carrying information, translate put LIPA PDN connections later.
If MMEMME judges to know access cell change according to the first access information and the second access information, CSG does not change, mobile subscription data whether is allowed to judge that LIPA PDN can be moved according to CSG signings, access network element is then notified to set up the related carryings of LIPA PDN, specially RAB assignment messages are sent to access network element or initial context sets up message, include LIPA PDN carrying information；If not allowing, send RAB assignment messages or initial context sets up message, do not include LIPA PDN carrying information, translate put LIPA PDN connections later.
If MME judges to know that access CSG changes according to the first access information and the second access information, send RAB assignment messages or initial context sets up message, the carrying mark not including LIPA PDN is translated put LIPA PDN connections later.
Situations below can also be included：
If judging to know that the local gateway IP address does not have according to the first access information and the second access information Change and access cell change, if being judged to allow movement according to user LIPA PDN subscription data, access network element is then notified to set up related 7 of LIPA PDN | carry, specially send RAB assignment messages or initial context sets up message, include LIPA PDN carrying information；If not allowing movement, send RAB assignment messages or initial context sets up message, do not include LIPA PDN carrying information, LIPA PDN connections are discharged later.
Step 502, if not setting up LIPA PDN RAB in step 501, MME initiation LIPA PDN connections, which are translated, releases journey.
Fig. 6 is periodicity of embodiment of the present invention route/tracing section updating schematic flow sheet, MME processing after UE is moved when the present embodiment is mainly used in RAU/TAU flows, as shown in fig. 6, this method includes：Step 600, the UE that there is LIPA PDN sends Route Area/tracing section updating request to MME；Step 601, if MME changes, target MME sends message request user's context to former MME, and the second access information of user can be sent to former MME by target MME；
If the MME of service user does not change, step 601, step 602 and step 603 are omitted, target MME and original MME are same network elements.
Step 602, former MME is according to UE in the second access information of target side, and UE sets up the first access information during LIPA PDN, subscription data related UE LIPA PDN mobility, judges whether LIPA PDN connections can keep；If it is then including the information such as LIPA PDN carrying ID in user's context, otherwise LIPA PDN information, which is not included in, is sent in target MME user's context.User's context is sent to target MME by former MME, if LIPA PDN are included within a context, and former MME also can indicate which is the related PDN of LIPA or carrying.Concrete mode is as follows：Cell change is accessed, whether former MME allows mobile subscription data to judge that LIPA PDN do not allow movement according to UE, and former MME does not include LIPA PDN information in user's context；If allowing movement, former MME retains the LIPA PDN information in user's context.
Access cell changes, if whether APN allows mobile subscription data not allow LIPA PDN to move, former MME does not include LIPA PDN information in user's context；If allowing movement, former MME retains the LIPA PDN information in user's context. Access CSG does not change, and whether former MME allows mobile subscription data to judge that the LIPA PDN do not allow movement according to UE CSG signings, and former MME does not include LIPA PDN information in user's context；If allowing movement, former MME retains the LIPA PDN information in user's context.Or,
Access CSG does not change, and the subscription data whether APN that former MME is accessed under the CSG according to UE moves judges that the LIPA PDN do not allow movement, and former MME does not include LIPA PDN information in user's context；If allowing movement, former MME retains the LIPA PDN information in user's context.
The L-GW address that user uses do not change, and user's signing allows LIPA PDN to move, and former MME retains the LIPA PDN information in user's context.
The L-GW address that user uses change, even if subscription data allows movement, former MME discharges LIPA PDN information, translates put LIPA PDN connections later from the context.
The cell change of user's access, but access CSG does not change or L-GW address do not change, and judges that LIPA PDN do not allow movement according to related subscription data, former MME does not include LIPA PDN information in user's context；If allowing movement, former MME retains the LIPA PDN information in user's context.
Access CSG changes, and former MME does not include LIPA PDN information in user's context, translates put LIPA PDN connections later.
Step 603, target MME sends context acknowledgement message to former MME；
Step 604, carry the step if UE includes configured information recovery wireless side in TAU requests and can just perform, be divided into two kinds of situations：First, if service UE MME does not change, it is that user sets up RAB that MME, which sends RAB assignment messages or initial UE context request/response message,.Before this, because MME saves the first access information when UE sets up LIPA PDN, the second access information that MME sets up LIPA PDN according to the access informations of UE first and UE and is, which is compared and combines UE subscription data, to be judged.If access information is inconsistent and subscription data does not allow LIPA PDN connections to move, MME does not include LIPA PDN in E-RAB/RAB assignment messages The RAB of connection, otherwise includes.Concrete operations may refer to step 501.Second, if the MME of the moon good business UE changes, target MME is that UE sets up RAB.
If MME judges to continue to keep after LIPA PDN connections are mobile, initiate PDN connections and translate to release journey and translate to put LIPA PDN connections.
Figure is switching flow schematic diagram of the embodiment of the present invention, and this implementation is mainly used in switching（Handover) during flow, the processing of MME or access network element after UE movements.The present embodiment determines that LIPA PDN are kept after UE movements by MME.As shown in fig. 7, this method includes：
Step 700, former access network element receives UE measurement report, the target cell information that UE is reported can also be received simultaneously, CSG ID, cell ID etc., UE is switched to Target cell by former access network element determination, sends handover required message to original MME, message includes the second access information of ownership goal cell；
Step 701, former MME is received after handover request, and forward handover request message is sent to target MME.
If service UE MME does not change, the step is then omitted.Before the message is transmitted, the access informations of UE second that former MME can be sent according to UE the first access information and former access network element carry out LIPA PDN mobile management, for details, reference can be made to above method embodiment.
Then, target MME sends message request target access network member（It is not shown) radio bearer is set up, if the container sent from former access network element（Container do not include or not the related carrying of LIPA PDN connections in the carrying that the related carrying of LIPA PDN connections or MME requests are set up in), target access network member does not set up the related carrying of LIPA PDN connections；Otherwise the related carrying of LIPA PDN connections is set up.
Step 702, target MME sends response message to former MME.
