摘要： Method of arranging a cellular radio network in a geographical area which is already covered by an existing cellular radio network, wherein cell clusters of the cellular radio network to be introduced and using a specific transmission frequency are located in areas determined by connecting at least two cells of the existing cellular radio network using the specific transmission frequency, and wherein the cell clusters are arranged such that they do not overlap with the cells of the existing cellular radio network. The cell clusters of the introduced cellular radio network may be adjusted by reducing the cell size of cell clusters of the introduced cellular radio network, and by introducing new cells into cell clusters of the introduced cellular radio network. The invention allows to reuse frequencies of an existing cellular radio network by an introduced cellular radio network in the same geographical area.

摘要： The invention relates to a method for performing a flexible multicast of multicast data to a multicast group within a telecommunication system wherein the multicast data is provided by a broadcast/multicast server and transferred to the users registered to the multicast group by means of channels. In the invention multi-channel multicast groups (B1,B2, . . . ) are provided. Each multi-channel multicast group offers at least one channel wherein a channel transports content. The availability and configuration of the multi-channel multicast group is announced to the users by means of an announcement multicast group (A). The user either initiates the changing to an announced multi channel multicast group or the user is forced by the operator to change in case the operator wants to control the allocation of resources.

摘要： The present invention proposes a solution for providing IMS services to users having circuit-switched controlled terminal being not adapted to provide IMS services to the users. In particular, it is proposed, in order to allow IMS to take the full call and service control, to place a user agent being responsible for the user ported to the IMS in a new node type called Mobile Access Gateway Control Function (MAGCF). This new node combines the logical functionality of a cellular switching center and the logical functionality of IMS. Further it is proposed to enhance a user's register, like HLR, to provide also information about the availability of a MAGCF node and about whether a particular user is enabled to use the MAGCF functionality.

摘要： The invention provides a solution for registering a terminal having a packet-switched and circuit-switched functionality in a packet-switched service domain, such as the IMS over a circuit-switched access domain. In particular it is proposed to send a packet-switched registration message packed in a circuit-switched transport bearer (USSD) to a circuit node (HLR, MSC, dispatcher) which selects an adapter node (IA) being responsible for performing a registration in the packet-switched service domain on behalf of the user using the information provided with the packet-switched registration message and by deriving and adding additional information.

摘要： A method and system for updating or handling the update of a media path between a first user terminal and a second user terminal in a telecommunications network is provided. According to an embodiment of the present invention, the media path includes one or more gateway nodes. Each gateway node includes a gating function for gating media packets. Each gating function has an associated controlling function for controlling the gating function. Responsive to a message indicating at an update of the gating at the gating function is required, the gating function arranges for a new gating to be opened while keeping the old gating open. The gating function determines when the media has been switched to the new path. Responsive to the determination, the gating function arranges for the old gating to be closed.

摘要： A mechanism is presented for performing a session transfer with Single Radio Voice Call Continuity, SRVCC, from a Packet Switched, PS, access to a Circuit Switched, CS, access of a telecommunications session that has been established over the PS access via an IP Multimedia Subsystem, IMS, network. The method includes receiving a request for the transfer of the session to the CS access. An indication of an already-seized media gateway, MGW, that has been established for use in one or more other sessions over the CS access is obtained from the IMS network. A MGW is selected as a Mobile-Media Gateway, M-MGW, for the session based on the obtained indication. Allocation of resources for the session in the CS access network is initiated, including specifying the MGW to be used as the Mobile-Media Gateway, M-MGW. Transfer of the session to the CS access is then initiated.
