Providing an indicator of presence of a first access network that is capable of interworking with a second access network

An apparatus, comprising:

• a memory;
• and
• at least one processor in communication with the memory, wherein the at least one processor and memory are configured to:
• send, to a mobile station, a control message, wherein the control message includes an indicator that a first access network is interoperable with a second access network, wherein the first access network has a first protocol, and the second access network has a second protocol;
• establish a personality for the mobile station, wherein the personality is used for communication between the mobile station and the first access network, wherein the personality specifies a configuration allowing the mobile station to use features of the first access network that enable interworking with the second access network, and wherein to establish the personality, the at least one processor is further configured to negotiate the personality used for communication between the mobile station and the first access network that for the mobile station;
• and
• send control information comprising multiple indicators regarding which neighbors of the first access network that the mobile station is currently in are first access networks that are capable of interworking with the second access network.

A mobile station, comprising:

• an interface to a wireless link;
• and
• at least one processor coupled to the interface and configured to:
• receive a control message via the interface from a first access network, wherein the control message includes an indicator that the first access network is interoperable with a second access network, wherein the first access network has a first protocol, and the second access network has a second protocol;
• perform a procedure to establish a personality for the mobile station, in response to receiving the control message, wherein the personality is used for communication between the mobile station and the first access network, wherein the personality specifies a configuration allowing the mobile station to use features of the first access network that enable interworking with the second access network, and wherein to perform the procedure, the at least one processor is further configured to negotiate the personality with the first access network for the mobile station;
• and
• receive control information comprising multiple indicators regarding which neighbors of the first access network that the mobile station is currently in are first access networks that are capable of interworking with the second access network.
