LOCATION REGISTRATION AND PAGING IN TELECOMMUNICATIONS NETWORK
First Claim
1. A method of operating a telecommunications network comprising at least one femtocell and at least one macrocell, the at least one femtocell and the at least one macrocell being associated with a Tracking Area, the method comprising:
- when a wireless terminal accesses or is about to access a femtocell, including an identifier of the femtocell in a Tracking Area Identity list provided to the wireless terminal whereby the wireless terminal avoids performing a Tracking Area Update when moving between the femtocell and another tracking area included in the Tracking Area Identity list;
when the wireless terminal is to be paged, initially issuing a paging message only to a portion of the cells having corresponding identifiers included in the Tracking Area Identity list.

Abstract
Methods and apparatus are provided for operating a telecommunications network (20) which comprises at least one femtocell and at least one macrocell, each femtocell and each macrocell being associated with a Tracking Area. The method comprises (when a wireless terminal (30) accesses a femtocell or possibly a cell in the vicinity of the femtocell) including an identifier of the femtocell in a Tracking Area Identity list provided to the wireless terminal (30), and thereby enabling the wireless terminal (30) to avoid performing a Tracking Area Update when moving between the femtocell and another tracking area included in the Tracking Area Identity list. The method also comprises (when the wireless terminal (30) is to be paged) initially issuing a paging message only to a portion of the cells having corresponding identifiers included in the Tracking Area Identity list. Optionally the method also comprises determining that the wireless terminal (30) is accessing the telecommunications network (20) through a femtocell.

11. A core network entity configured to communicate with a radio access network comprising at least one femtocell and at least one macrocell, the at least one femtocell and the at least one macrocell being associated with a Tracking Area, the core network entity comprising:
-
a Tracking Area Identity list builder configured to include an identifier of a femtocell in a Tracking Area Identity list provided to a wireless terminal when the wireless terminal accesses the femtocell, whereby inclusion of the identifier avoids the wireless terminal performing a Tracking Area Update when moving between the femtocell and another tracking area included in the Tracking Area Identity list; a paging unit configured, when the wireless terminal is to be paged, to initially issue a paging message only to a portion of the cells having corresponding identifiers included in the Tracking Area Identity list. - View Dependent Claims (12, 13, 14, 15, 16, 17, 18, 19, 20)
