- FIG. 7 is a flowchart of an application example 1 of the present invention.
- the EPC network is taken as an example to describe a method for processing a local access connection when a user locally accesses subscription data changes, as follows:
- This embodiment uses the user CSG (closed user group) subscription timeout saved in the core network mobility management unit MME as an example to describe the local access connection processing method.
- Step 701 The core network mobility management unit MME saves the user's CSG subscription information. If the user is in the connected state and accesses the network through the hybrid mode home base station, the MME detects that the CSG ID corresponding to the home base station times out and causes the CSG membership of the user. When a change occurs (from a CSG subscription user to a non-CSG subscription user), the MME needs to initiate a local access PDN connection release;
- the MME initiates the release of all locally accessed PDN connections that have been activated. If the user subscribes to the Wildcard APN, the MME initiates the release of the local access PDN connection corresponding to the APN bound to the CSG in the session management context, and the local access PDN connection corresponding to the APN that is not bound to the CSG in the session management context is not # Zhang handled.
- Each CSG subscription information includes a timeout period for the user to use the CSG ID.
- a CSG ID timeout period expired by the user expires, indicating that the user's subscription to the CSG ID is invalid, the user's membership in the CSG is from the CSG.
- the signing user becomes a non-CSG signing user.
- Step 702 The MME sends a new CSG membership relationship (from a CSG subscription subscriber to a non-CSG subscription subscriber) to the HeNB through the UE context modification request message (hereinafter referred to as SI AP) in the S1 interface application protocol, and the HeNB uses the new CSG.
- SI AP UE context modification request message
- the member relationship performs the air interface resource allocation
- Step 703 The HeNB responds to the SI AP UE context modification response message;
- Step 704 The MME initiates a local access PDN connection deletion process according to the determination result of step 701.
- Step 705-706 the user plane tunnel corresponding to the local access connection in the S-GW and the L-GW is released;
- Step 707 The S-GW sends a session deletion response message to the MME.
- Steps 708-709 the air interface bearer release corresponding to the local access connection.
- FIG. 8 is a flowchart of an application example 2 of the present invention.
- the EPC network is taken as an example to describe a method for processing a local access connection when a user locally accesses subscription data changes, as follows:
- the subscription data update causes the user CSG subscription saved in the core network mobility management unit MME to be invalid as an example to perform a local access connection processing method.
- Step 801 The user CSG subscription data is updated in the HSS, and the HSS sends an insert user data request message to the MME, where the updated CSG subscription information is carried.
- the MME When the MME discovers that the current CSG membership of the user changes according to the new CSG subscription message, that is, the CSG ID subscription corresponding to the currently connected home base station of the connected state fails, and the CSG membership of the user changes (from the CSG subscription user).
- the subscriber is a non-CSG subscriber, the MME needs to initiate a local access PDN connection release procedure.
- the MME initiates release of all local access PDN connections that have been activated. If the user subscribes to the Wildcard APN, the MME initiates the release of the local access PDN connection corresponding to the APN bound to the CSG in the session management context, and the local access PDN connection corresponding to the APN that is not bound to the CSG in the session management context is not # Text processing.
- Step 802 The MME inserts a user data response message into the HSS response.
- Steps 803 to 810 are the same as steps 702 to 709 of the application example 1, and are not described here.
- Application example 3
- FIG. 9 is a flowchart of an application example 3 of the present invention.
- the EPC network is taken as an example to describe a method for processing a local access connection when a user locally accesses subscription data changes, as follows:
- a description of a local access connection processing method is performed by taking a user CSG subscription timeout saved in the core network mobility management unit MME as an example.
- Step 901 The core network mobility management unit MME saves the subscription information of the CSG of the user. If the user is in the connected state and accesses the network through the hybrid mode home base station, the MME detects that the CSG ID corresponding to the home base station times out and causes the CSG member of the user. When the relationship is changed (from the CSG subscription user to the non-CSG subscription user), the MME needs to instruct the HeNB to trigger the local gateway L-GW to initiate local access PDN connection release;
- the MME instructs the home base station to touch The local gateway initiates the release of all locally accessed PDN connections that have been activated. If the user subscribes to the Wildcard APN, the MME instructs the home base station to trigger the release of the local access PDN connection corresponding to the APN bound to the CSG in the session management context of the local gateway, and the APN that is not bound to the CSG in the session management context. Local access to the PDN connection is not processed.
- Step 902 The MME sends a user CSG membership or a local access connection deactivation indication to the HeNB by using an evolved radio access bearer (E-RAB) modification request message in the S1 interface message.
- E-RAB evolved radio access bearer
- the modification parameters of the radio bearers corresponding to all the local access PDN connections carry the user CSG membership or the local access connection. Deactivate the indication. If the MME needs to instruct the home base station to trigger the local gateway to initiate the PDN connection release corresponding to the APN bound to the CSG in the session management context, the modification of the radio bearer corresponding to the local access PDN connection corresponding to the APN with the binding relationship
- the parameter carries the user CSG membership or the local access connection deactivation indication.
- the HeNB may find a corresponding local access connection and an L-GW serving the same according to the radio bearer carrying the indication, and trigger the L-GW to initiate a local access PDN connection release.
- the MME uses the user CSG membership relationship parameter to indicate that the HeNB triggers the L-GW to initiate a local access PDN connection release
- the HeNB needs to compare it with the previous CSG membership relationship. If the user is found to change from the CSG member to the non-CSG member, the L is triggered. - The GW initiates the release of the local access PDN connection corresponding to the radio bearer.
- the HeNB triggers the L-GW to initiate the local access PDN connection release corresponding to the radio bearer after receiving the local access connection deactivation parameter indication.
- Step 903 The HeNB responds to the MME with the evolved radio access bearer modification response message.
- Step 904 The HeNB, according to the determination of step 902, notifies the L-GW to initiate corresponding local access by using the Sxx interface or the internal interface between the HeNB and the L-GW.
- the PDN connection is released, where the Sxx interface is an interface that has not been standardized;
- Step 905 The L-GW returns a notification response message.
- Steps 906-909 the L-GW initiates a local access PDN connection release process
- Step 910-911 the local radio access corresponding to the PDN connection is released.
- FIG. 10 is a flowchart of an application example 4 of the present invention.
- the EPC network is taken as an example to describe a method for processing a local access connection when a user locally accesses subscription data changes, as follows:
- the subscription data update causes the user CSG subscription saved in the core network mobility management unit MME to be invalid as an example to perform a local access connection processing method.
- Step 1001 The user CSG subscription data is updated in the HSS, and the HSS sends an insert user data request message to the MME, where the updated CSG subscription information is carried;
- the MME When the MME discovers that the current CSG membership of the user changes according to the new CSG subscription message, that is, the CSG ID subscription corresponding to the currently connected home base station of the connected state fails, and the CSG membership of the user changes (from the CSG subscription user).
- the MME needs to instruct the HeNB to trigger the local gateway to initiate a local access PDN connection release.
- the MME instructs the home base station to trigger the local gateway to initiate all local access PDN connection activations that have been activated. If the user subscribes to the Wildcard APN, the MME instructs the home base station to trigger the release of the local access PDN connection corresponding to the APN bound to the CSG in the session management context of the local gateway, and the APN that is not bound to the CSG in the session management context.
