Abstract  Abstract

UNINTERRUPTED TRANSMISSION DURING A CHANGE IN CONFIGURATION OF ENCRYPTION. Techniques are described for sending information without interruption during a change in the configuration of encryption. A UserS equipment (110) communicates with a wireless communication network for a call. THE EU sends first information to the wireless network using a first encryption of configuration (612). For a change in configuration of encryption the eu selects an activation time for a second configuration of enciphering (614) and sends a security message with the activation time (616). This activation time is the time in which the eu applies the second encryption of configuration to transmission sent to the wireless network. The following THE EU sends second information for example a message of reporting the measurement using the first configuration of encryption after sending the security message and before the activation time (618). THE EU sends third information using the second encryption configuration after the activation time (622).

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.
