Abstract  Abstract

The invention claims techniques for continuously transmitting information during a ciphering configuration change technology. User Equipment UE (110) to perform call communication with the wireless communication network. the UE sends first information (612) to the wireless network using a first ciphering configuration. for a change in ciphering configuration the UE selects a second ciphering configuration activation time (614) and sending the security message with the activation time (616). the activation time is the UE to transmit to the wireless network transmission using the second ciphering configuration time. the UE subsequently and sending second information (e.g. a measurement report message) (618) using the first ciphering configuration after sending the security message before said activation time. the UE sends third information (622) using the second ciphering configuration after the activation time.

Techniques for sending information without interruption during a change in ciphering configuration are described. A user equipment (UE) communicates with a wireless communication network for a call. The UE sends first information to the wireless network using a first ciphering configuration. For a change in ciphering configuration the UE selects an activation time for a second ciphering configuration and sends a security message with the activation time. This activation time is the time at which the UE applies the second ciphering configuration to transmission sent to the wireless network. The UE thereafter sends second information (e.g. a measurement report message) using the first ciphering configuration after sending the security message and before the activation time. The UE sends third information using the second ciphering configuration after the activation time.
