Method and apparatus for releasing connection with local GW when UE moves out of the residential/enterprise network coverage
In some examples, a user equipment (UE) obtains a connectivity in a first cell, the connectivity identified by an access point name (APN), where the APN corresponds to a first type of connection, and where the first type of connection provides access to services in a local data network. The UE camps on a second cell, determines if the connectivity is not supported in the second cell based on broadcast information from the second cell, the broadcast information comprising information of the second cell, and in response to determining that the connectivity is not supported in the second cell, disconnect the connectivity, wherein the disconnecting comprises sending a Non Access Stratum (NAS) message via the second cell.
1. A method of a user equipment (UE), comprising:
obtaining a connectivity in a first cell, the connectivity identified by an access point name (APN), wherein the APN corresponds to a first type of connection, and wherein the first type of connection provides access to services in a local data network;
camping on a second cell;
determining if the connectivity is not supported in the second cell based on broadcast information from the second cell, the broadcast information comprising a tracking area identity (TAI) of the second cell, wherein the determining comprises matching the TAI with a list of TAIs obtained from a core network; and
if the connectivity is not supported in the second cell, disconnecting the connectivity, wherein the disconnecting comprises sending a Non Access Stratum (NAS) message via the second cell.
2. The method of claim 1 , further comprising storing, in the UE, a plurality of APNs corresponding to the first type of connection.
3. The method of claim 1 , wherein the connectivity is authorized by a network element in the core network.
4. The method of claim 1 , wherein the determining that the connectivity is not supported comprises determining that a continuity of the connectivity in the second cell is not allowed.
5. The method of claim 4 , wherein the connectivity of the UE with the first cell comprises the first type of connection, and the determining that the continuity of the connectivity in the second cell is not allowed comprises determining that the first type of connection is not allowed in the second cell.
6. The method of claim 1 , wherein the determining that the connectivity is not supported in the second cell comprises determining that a continuity of the connectivity is not allowed when the UE moves from the first cell to the second cell.
7. The method of claim 6 , wherein the determining that the continuity of the connectivity is not allowed is based on a value of a parameter received by the UE.
8. A user equipment (UE) comprising:
at least one processor configured to:
obtain a connectivity in a first cell, the connectivity identified by an access point name (APN), wherein the APN corresponds to a first type of connection, and wherein the first type of connection provides access to services in a local data network;
camp on a second cell;
determine if the connectivity is not supported in the second cell based on broadcast information from the second cell, the broadcast information comprising a tracking area identity (TAI) of the second cell, wherein the determining comprises matching the TAI with a list of TAIs obtained from a core network; and
in response to determining that the connectivity is not supported in the second cell, disconnect the connectivity, wherein the disconnecting comprises sending a Non Access Stratum (NAS) message from the UE via the second cell.
9. The UE of claim 8 , wherein the at least one processor configured to store, in the UE, a plurality of APNs corresponding to the first type of connection.
10. The UE of claim 8 , wherein the connectivity is authorized by a network element in the core network.
11. The UE of claim 8 , wherein the determining that the connectivity is not supported comprises determining that a continuity of the connectivity in the second cell is not allowed.
12. The UE of claim 11 , wherein the connectivity of the UE with the first cell comprises the first type of connection, and the determining that the continuity of the connectivity in the second cell is not allowed comprises determining that the first type of connection is not allowed in the second cell.
13. The UE of claim 8 , wherein the determining that the connectivity is not supported in the second cell comprises determining that a continuity of the connectivity is not allowed when the UE moves from the first cell to the second cell.
14. A non-transitory storage medium storing instructions that upon execution cause a user equipment (UE) to:
obtain a connectivity in a first cell, the connectivity identified by an access point name (APN), wherein the APN corresponds to a first type of connection, and wherein the first type of connection provides access to services in a local data network;
camp on a second cell;
determine if the connectivity is not supported in the second cell based on broadcast information from the second cell, the broadcast information comprising a tracking area identity (TAI) of the second cell, wherein the determining comprises matching the TAI with a list of TAIs obtained from a core network; and
in response to determining that the connectivity is not supported in the second cell, disconnect the connectivity, wherein the disconnecting comprises sending a Non Access Stratum (NAS) message via the second cell.
