Abstract
A method and system for providing a User Equipment (UE) (101) with a Tracking Area Identity (TAI) list during a Tracking Area Update (TAU) procedure. The TAI is UE specific and is based on a visitation history (305) of the UE (101). If a pre-existing visitation history of the UE does not exist, a TAI is compiled using other UEs featuring at least one operational similarity as the current UE (101).
Claims15
A method of providing a User Equipment, UE specific Tracking Area Identity, TAI, list, the method comprising:
- storing current visitation information of the specific UE in a network node-the current visitation information being related to a last visited Tracking Area, TA, and a time of visit;
- compiling a visitation history based on the current visitation information and pre-existing visitation information;
- evaluating the visitation history of the specific UE;
- and
- providing a TAI list including possible TAs which is likely be utilized by the specific UE based on the visitation history of the UE.
A network node for providing a Tracking Area Identity, TAI, list, the node being configured to:
- store current visitation information of a specific User Equipment, UE, in the network node, the current visitation information being related to a last visited Tracing Area, TA, and a time of visit;
- compile a visitation history based on the current visitation information and pre-existing visitation information;
- and
- evaluate the visitation history of the specific UE, the node further configured to provide a TAI list of possible TAs which are likely to be visited by the specific UE based on the visitation history of the UE.
