Abstract:
A method of reselecting cells in a packet mode cellular mobile radio system, which method includes a step in which a mobile station connected in packet mode to a server cell attempts to connect in packet mode to a target reselected cell, which method is essentially characterized in that if the mobile station cannot connect to the target reselected cell, it sends the network cell update information indicating its server cell as the new cell.
Abstract:
The invention provides mobile radio system access network equipment including means for coordinating resources for circuit-switched mode services and packet-switched mode services, which resource coordination means are limited to means for coordinating sending circuit-switched mode service paging messages to a mobile station in packet-switched mode.
Abstract:
A mobile station in a mobile radio system can send different types of packet mode resource requests to a network, corresponding to different transfer modes that can be supported by the mobile station, a mobile station being able to use one or the other of request types corresponding to transfer modes that it supports, in accordance with its requirements. In a method of allocating packet mode resources in the mobile radio system, for signaling data transfer in the uplink direction, the signaling being liable to generate an allocation of packet mode resources in the uplink direction for user data transfer, a mobile station uses a type of packet mode resource request corresponding to a transfer mode best suited to the requirements of the user data transfer.
Abstract:
A method for optimising quality of service in the packet-switched domain of a mobile communication system, a method wherein: a core network entity of said system sends to a radio access network entity of said system a request for the setting-up or reconfiguration of a radio bearer for a packet session for a mobile station, said request including first information derived from quality of service information contained in a corresponding request received by said core network entity, said core network entity adds to said request second information known at its level and which can be used, together with said first information, to perform a call admission control at the radio level.
Abstract:
A multimedia call session control method for use in a cellular mobile radio system, said method including: a negotiation step for determining the characteristics of the components of said session, and a step for allocating resources based on characteristics determined in the negotiation step, which method is essentially characterized in that the negotiation step includes the following steps: at least one of the parties to the call is informed of the capacities of its server radio access network, at least in its server cell, and the capacities of said server radio access network are taken into account in said negotiation, in order to be able to allocate corresponding resources.
