摘要 |
The present invention is related to a method and arrangement in a mobile station operating in standby mode and monitoring a first control channel in a first radio communication network. The transmission of messages (703-708) on the first control channel occurs in periodic occuring frames (700). Each frame (700) comprises a first sequence of messages (701), in which no message is addressed to a specific mobile station, and a second sequence of messages (702) that may comprise messages addressed to specific mobile stations. The mobile station determines for at least a first frame (700) a time period during which no part of a message, belonging to the second sequence of messages (702), will be transmitted. Said time period is used by the mobile station to perform actions other than receiving radio signals carrying the first control channel, e.g. entering sleep mode or scanning for control channels in a second radio communication network. |
