Abstract
A mobile station determines whether the mobile station is receiving an overhead message in tunnel mode during a handover procedure of the mobile station from a source wireless access network to a target wireless network. The source and target wireless access networks are according to different technologies. In response to determining that the mobile station is in the tunnel mode, tunnel mode processing of the overhead message is performed. In response to determining that the mobile station is not in the tunnel mode, different processing of the overhead message is performed.
Claims20
A method performed by a mobile station, comprising:
- determining whether the mobile station is in a tunnel mode for receiving an overhead message during a handover procedure of the mobile station between different types of wireless access networks;
- in response to determining that the mobile station is in the tunnel mode, performing first processing with respect to the overhead message, wherein the overhead message is associated with a collection of parameters, and wherein performing the first processing comprises setting any parameter that is part of the collection and that is not received in the overhead message in tunnel mode to a corresponding selected value;
- and
- in response to determining that the mobile station is not in the tunnel mode, performing second, different processing with respect to the overhead message.

A mobile station comprising:
- a communications interface to communicate over-the-air;
- a processor to:
- determine whether the mobile station is receiving an overhead message in tunnel mode during a handover procedure of the mobile station from a source wireless access network to a target wireless network, wherein the source and target wireless access networks supports different technologies;
- in response to determining that the mobile station is in the tunnel mode, performing tunnel mode processing of the overhead message;
- when in tunnel mode, adjust a value of an indicator for indicating whether parameters of the overhead message are up to date;

- in response to determining that the mobile station is not in the tunnel mode, performing different processing of the overhead message.
4 more elements
At least one non-transitory machine-readable storage medium storing instructions that upon execution cause a mobile station to:
- determine whether the mobile station is receiving an overhead message in tunnel mode during a handover procedure of the mobile station from a source wireless access network to a target wireless network, wherein the source and target wireless access networks are according to different technologies;
- in response to determining that the mobile station is in the tunnel mode, performing tunnel mode processing of the overhead message, wherein the overhead message is associated with a collection of parameters, and wherein performing the tunnel mode processing comprises setting any parameter that is part of the collection and that is not received in the overhead message in the tunnel mode to a corresponding selected value;
- and
- in response to determining that the mobile station is not in the tunnel mode, perform different processing of the overhead message.
