Abstract

A method can include allocating a temporary mobile subscriber identity for a user equipment during a location update procedure. The method can also include allocating, during the allocating of the temporary mobile subscriber identity, a unique network resource identifier value for the whole network element, wherein temporary mobile subscriber identity allocation avoids being location area based. The method can further include providing, to the user equipment, a location area identifier, temporary mobile subscriber identity with the unique network resource identifier value, and an indication to skip location area identifier checking when performing circuit-switched fallback. Certain embodiments of the present invention can thus minimize the LAU by the UE and allow the network not to require perfect alignment of TA and LA.
