    Abstract: In a cellular telecommunications system or network, tags are associated with one or more system control parameters. For example, a given tag value may be indicative of particular values for on e or more system information parameters. In each cell, a base station (BS) transmits or braodcasts currently valid tag values. Syst em information blocks including the system information parameters themselves (which correspond to particular tag(s)) are also broadcast by base stations. A mobile station receiving a valid tag value from a base station determines whether or not it has to read syste m information block(s) corresponding to that tag depending upon whether the base station has already stored or cached such block(s) corresponding to the tag value. As will be appreciated by those skilled in the art, different embodiments of the instant invention may result in the mobile station not having to re-read identical system information each time it changes cells, or while moving in the same cell. This may conserve radio resources and reduce battery consumption, thereby improving standby time of the mobile station.

    Abstract: In a cellular telecommunications system, a method of dynamically allocating packet data radio channels among users competing in a same cell for the channels involves determining a user ranking for each of plural competing users in the cell, and classifying each of the plural competing users into one of plural ranking classes. A number of the packet data radio channels available for each of the ranking classes is then determined, after which the users within each ranking class are sorted by ranking. The packet data radio channels are allocated to the users by sorted position within ranking classes. The user ranking for each of the plural competing users in the cell is related to a weighted combination of plural measures of performance for the user.
