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.
