Abstract  Abstract

Techniques for sending information without interruption during - a change in ciphering configuration are described. A user equipment UE (110) - communicates with a wireless communication network for a call. The lYE sends first Start information to the wireless network using a first ciphering configuration (612). For 62 a change in ciphering configuration the UE selects an activation time for a second 62 ciphering configuration (614) and sends a security message with the activation time Send first information using (616). This activation time is the time at which the IJE applies the second ciphering Fafirst ciphering configuration configuration to transmission sent to the wireless network. The UE thereafter sends 4 second information e.g. a measurement report message) using the first ciphering Select an activation time for a configuration after sending the security message and before the activation time (618). Fsecond ciphering configuration The UE sends third information using the second ciphering configuration after the - 616 activation time (622). - Send a security message Fwith the activation time -f 618 Send second information (e.g. ameasurement report message) S using the first ciphering configuration after sending the security message and before the activation time N -620 Receive an acknowledgement for the security message el before the activation time o Send third information using there second ciphering configuration after the activation time C End
