    Abstract: A method and apparatus is provided for providing one or more point-to-multipoint services, such as a multimedia broadcast/multicast service (MBMS), to one or more mobile terminals, or user equipment (UE). When one or more mobile terminals move to a new area of a mobile communication system managed by a different network element after joining a service, information is transmitted between network elements in a manner that facilitates the continued reception of the service by the mobile terminals that have moved while conserving network resources and increasing efficiency of the mobile communication system.

    Abstract: Method for transmitting a power control bit and for detecting a power control rate, in which a transmission pattern of power control bits is varied with a power control rate, for making blind detection of the power control rate varied from time to time possible, wherein, when change of the power control rate is required, a base station (or a mobile station) generates the transmission pattern of the power control bits varied with the power control rate to be changed, and transmits to the mobile station (or base station), and the mobile station (or the base station) determines the changed power control rate from the received transmission pattern of the power control bits, thereby permitting stable detection of the power control rate varied from time to time.

    Abstract: A method and apparatus for establishing a radio bearer of a point-to-multipoint multimedia service by utilizing a reference configuration of radio bearer parameters for quickly establishing a radio bearer when a mobile terminal moves between cells. By configuring radio bearer parameters for a specific point-to-multipoint service by utilizing a reference configuration such that the same, or equal value, protocol and channel parameters are set for each cell, different cells in a communication system in which a specific point-to-point service is provided are able to configure the radio protocol entities, channels, and radio bearer at the same time by utilizing the same parameter values, thereby minimizing delay in establishing a radio bearer and minimizing data loss occurring during handover, conserving network resources, and enhancing reception performance via soft combining.
