摘要： A method is provided to activate a packet data protocol (PDP) context in a cellular network. This may include determining whether users associated with the cellular network may receive multicast or broadcast data and activating the PDP context based on the determination. The determination may be based on a trigger that occurs when a notification is sent to the Serving GPRS Support Node (SGSN). The SGSN may get notified based on a periodic status query, an update message and/or an activation request, for example.

摘要： The present invention relates to a method and system for performing a multicast transmission in a cellular network, wherein an identification information, which indicates terminal devices and/or areas in which authorized terminal devices are assumed to be located, is transmitted from a core network (100) to a radio access network of the cellular network by using a control information transmission protocol. Then, a signalling connection of a control and user data transmission protocol is establishing based on said identification information and used for transmitting multicast related data and corresponding control information between the core network (100) and the radio access network. Thereby, already defined protocol layers can be used for implementing multicast transmission, while modifications are minimized.

摘要： The invention is a system and method of transmitting control information and user data, relating to multicast or broadcast services, between a first information entity (110) within at least one mobile station (104) and a second information entity (114) within a controller (106) of a wireless network (102) in which the at least one mobile station is located. The process of the invention includes originating control information from at least one first information entity; encoding the control information at the at least one mobile station on a logical channel; transmitting the logical channel on a physical channel from the at least one mobile station to the controller; decoding the physical and the logical channels at the controller and providing the control information to the second information entity; providing user data at the second information entity; encoding the user data at the controller on a logical channel; encoding the logical channel, on which the user data is encoded, on a physical channel and wirelessly transmitting the physical channel on which the logical channel is encoded from the controller to the at least one mobile station; and decoding the physical channel and the logical channel on which the user data is encoded at the at least one mobile station and providing the user data to at least one of the first information service entities.

摘要： The invention is directed to a method for providing a service to a user comprising the steps of defining an area in which the service is available, transmitting information to a plurality of users in the said area at the same time via a common channel to determine if the user is in the said area. If the user is in the said area, the user is arranged to receive the information transmitted on the common channel, and if the user is outside the said area, the user is provided with the option of receiving the information via a dedicated channel or the option of not receiving the information. The user is charged for the information received via the common channel in dependence with the selected option.

摘要： The power level of multicast data transmissions in a wireless communications network are controlled. Power level information is provided in a transmitted channel received by a user equipment. The user equipment measures the power level of a received signal. It compares the measured power level to the power level indicated by the power level information provided in the transmitted channel. Power level measurement information is included in a message sent by the user equipment depending on the results obtained when the power level measured by the user equipment is compared to the power level indicated by the power level information provided in the transmitted channel.

摘要： The present invention is related to a method and system for multicast service announcement in a cell that includes a core network, a UTRAN, and one or more mobile network nodes. The UTRAN includes a RNC. The RNC continuously sends multicast service announcements in a frame over a channel such as a PICH. The frame may include a type field and an indication field where the type field contains information related to the type of information in the indication field, or the frame may include a current service announcement identification field, a next service announcement identification field, and a time offset field. The type field can be used also to separate long term scheduling announcement or service advertising frames from the multicast/broadcast data frames, or the type field can be used to separate the multicast/broadcast control frames from the multicast/broadcast data frames.
