A method of managing user equipment (UE) identifiers in a communication
system that includes a first wireless communications system that has a
core network and a second wireless communications system that includes
several short range access points using licensed wireless frequencies and
a network controller for communicatively coupling a user equipment to the
core network. The method receives a radio resource control (RRC)
connection request message from the UE. The method allocates a first
identifier to the UE. The method sends an RRC connection setup message
that includes the first identifier from the access point to the UE. The
method sends a connection management services request message and the
first identifier. The network controller determines the first identifier
is in use. The method sends a mobility info message that includes a
second identifier which is different than the first identifier from the
access point to the UE.
