Abstract
A method performed by user equipment (UE) includes receiving a request to access a service unavailable through a first network cell associated with the UE, and receiving a message from an access device associated with the first network cell, wherein the message identifies a plurality of second network cells providing the service.
Claims26
A method performed by user equipment (UE), comprising:
- receiving a request to access a service unavailable through a first network cell associated with the UE;
- receiving an RRC Connection Release message from an access device associated with the first network cell directing the UE to release a connection with the access device, wherein the message identifies a plurality of second network cells providing the service and contains system information of the plurality of second network cells and location areas of the plurality of second network cells;
- releasing the connection with the access device;
- selecting one of the plurality of second network cells belonging to the same location area as the location area in which the UE is registered;
- and
- initiating a connection to the selected one of the plurality of second network cells.
A method performed by user equipment (UE), comprising:
- receiving a request to access a service unavailable through a first network cell associated with the UE in an evolved universal terrestrial radio access network (E-UTRAN);
- receiving an RRC Connection Release message from an evolved node B (eNB) associated with the first network cell directing the UE to release a connection with the eNB, wherein the message identifies a plurality of second network cells providing the service and contains system information of the plurality of second network cells and location areas of the plurality of second network cells;
- releasing the connection with the eNB;
- selecting one of the plurality of second network cells belonging to the same location area as the location area in which the UE is registered;
- and
- initiating a connection to the selected one of the plurality of second network cells.
A user equipment (UE) comprising:
- one or more processors configured to:
- receive a request to access a service unavailable through a first network cell associated with the UE;
- receive an RRC Connection Release message from an access device associated with the first network cell directing the UE to release a connection with the access device, wherein the message identifies a plurality of second network cells providing the service and contains system information of the plurality of second network cells and location areas of the plurality of second network cells;
- release the connection with the access device;
- select one of the plurality of second network cells belonging to the same location area as the location area in which the UE is registered;
- and
- initiate a connection to the selected one of the plurality of second network cells.
