  • Cell reselection signalling method
    Patent number: 8364196
    Abstract: The invention relates to methods pertaining to cell reselection in a cellular telecommunication system. According to the invention, a connection setup rejection message is used to direct a mobile communication means to attempt a new connection with certain parameter values such as a certain carrier frequency. A plurality of parameter values may as well be indicated in the message, which allows the network to direct the mobile communication means to make a connection setup request to a specific cell, for example. The connection setup rejection message can be for example the CONNECTION SETUP REJECT message of the RRC protocol.
