Patent ID: 8429728

Claim:
A method for use in a computing device of a communication system, wherein the communication system supports two or more access technologies for permitting a given communication device to access the communication system, and wherein at least part of a first security context is generated at the computing device for the given communication device permitting the given communication device to access the communication system via a first access technology, the method comprising: generating at the computing device at least part of at least a second security context for the given communication device such that the given communication device is pre-registered to access the communication system via at least a second access technology while maintaining the first security context and such that the given communication device is able to continue to access the communication system via the first access technology and is pre-registered to subsequently access the communication system via the second access technology; wherein the second security context is generated before a decision is made to perform a handover from the first access technology to the second access technology.
