Method and arrangement in a road communication network
First Claim
1. A method for scheduling operation of a mobile station (MS1) in a radio communication system, the mobile station (MS1) being in standby mode monitoring a first control channel (CC1) on which a first base station (BS1) in a first radio communication network (NET1) in the system continuously transmits messages (703-708), each message comprising at least one word of information bits (40), messages potentially of concern to the mobile station (MS1) being transmitted on the first control channel (CC1) in periodic occurring frames (700), each frame comprising a first sequence of messages (701) in which no message is addressed to a specific mobile station monitoring the first control channel (CC1), the method comprising the steps of for at least a first of the frames:
- (a) computing (1134) a time period (1307), according to a predetermined formula based on the extent of the first message sequence (701), during which time period (1307) all transmitted words (703-706) belong to messages in the first sequence of messages (701) in the first frame (700);
(b) performing (1135) a predetermined action, other than receiving radio signals carrying the first control channel (CC1), during the determined time period (1307).

Abstract
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.

18. A mobile station (MS1) for operation in a radio communication system comprising at least a first radio communication network (NET1), said network comprising at least a first base station (BS1) which on a first control channel (CC1) continuously transmits messages (703-708), each message comprising at least one word of information bits (40), messages potentially of concern to the mobile station (MS1) being transmitted on the first control channel (CC1) in periodic occurring frames (700), each frame (700) comprising a first sequence of messages (701) in which no message is addressed to a specific mobile station monitoring the first control channel (CC1), the mobile station (MS1) comprising:
-
time period computing means (1003) arranged for computing a time period (1307), for at least a first of the frames (700) occurring when the mobile station (MS1) is operating in standby mode monitoring the first control channel (CC1), using a formula based on the extent of the first message sequence (701), during which time period (1307) all transmitted words (703-706) belong to messages in the first sequence of messages (701); controlling means (1010) arranged for scheduling the mobile station (MS1) to perform to perform a predetermined action other than receiving radio signals carrying the first control channel (CC1) during the determined time period (1307). - View Dependent Claims (19, 20, 21, 22, 23, 24, 25, 26, 27, 28, 29, 30, 31, 32, 33, 34)
