Abstract  Abstract

PROBLEM TO BE SOLVED: To transmit information without interrupting communications during a change in ciphering configuration.

SOLUTION: User equipment (UE) communicates with a wireless communication network for a call. The UE transmits first information to the wireless network using a first ciphering configuration (612). For a change in ciphering configuration the UE selects an activation time for a second ciphering configuration (614) and transmits a security message with the activation time (616). This activation time is the time at which the UE applies the second ciphering configuration to the transmission to the wireless network. The UE thereafter transmits second information (e.g. a measurement report message) using the first ciphering configuration after transmitting the security message before the activation time (618). The UE transmits third information using the second ciphering configuration after the activation time (622).
