Abstract
A mobile station attached to a first type service domain determines that the mobile station should deregister in a second, different type service domain. In response to the determination to deregister, a deregistration request is sent through the first type service domain. The deregistration request indicates that the mobile station is to be deregistered in the second type service domain.

1-21. (canceled)
A method comprising:
- at a mobile station:
- determining, while attached to a first type service domain, that the mobile station is to be deregistered in a second type service domain;
- and
- in response to the determining, sending a message through the first type service domain, the message indicating that the mobile station is to be deregistered in the second type service domain,
- wherein the first type service domain and the second type service domain are different, wherein the first type service domain is one of a circuit-switched service domain or a packet-switched service domain, and the second type service domain is the other one of the circuit-switched service domain or the packet-switched service domain.
A non-transitory computer readable memory medium storing programming instructions that, when executed at a mobile station that includes a processor and a wireless interface, cause the processor to perform a method including:
- determining, while the mobile station is attached to a first type service domain, that the mobile station is to be deregistered in a second, different type service domain;
- and
- sending, in response to the determining, a message through the first type service domain via the wireless interface, message indicating that the mobile station is to be deregistered in the second type service domain,
- wherein the first type service domain comprises one of a circuit-switched service domain or a packet-switched service domain, and the second type service domain comprises the other one of the circuit-switched service domain or the packet-switched service domain.
A mobile station, comprising:
- a wireless interface;
- and
- a processor coupled to the wireless interface;
- wherein the processor and wireless interface are configured to:
- determine, while the mobile station is attached to a first type service domain, that the mobile station is to be deregistered in a second type service domain;
- and
- send, in response to the determining, a message through the first type service domain, the message indicating that the mobile station is to be deregistered in the second type service domain,
- wherein the first type service domain comprises one of a circuit-switched service domain or a packet-switched service domain, and the second type service domain comprises the other one of the circuit-switched service domain or the packet-switched service domain.
The mobile station of claim 41, wherein the first type service domain is the circuit-switched service domain, and the second type service domain is the packet-switched service domain, wherein to send the message, wherein the processor and wireless interface are further configured to:
- send the message in a short message service (SMS) message to a mobile switching center in the circuit-switched service domain.
