Description of the invention (8 Printed by the Consumer Cooperative of the Intellectual Property Bureau of the Ministry of Economic Affairs, UE User Equipment (Mobile) In the network architecture described here, N_ISDN is used for call system, while STM, AAL2 or IP are used Controlled by the holder and used by the user ^. The generation of control tones is omitted in this description and should be manipulated in other well-known ways. The media gate address can be transmitted on BICC, ISDN, for example as a secondary layer Transport address, in order to obtain tsc and / or media gateway address. It uses a number of services, routing analysis or B-number analysis; then, select TSC for outgoing calls to ISDN. The media gateway is based on Manipulation requires, for example, the capabilities required for calling such devices as CODECs, encoding, compression, framing, announcement machines, tone recorders, or modems. For the sake of brevity, in these examples, Only explain B-number analysis, select mainly according to the destination. 'According to the destination, a group of MGWs with different capabilities can be obtained. Then, select the required capabilities, such as CCDs, modem support, and Internet.

Invention Description (9) code, in which the ISDM user plane can be terminated. Outside of the DPC transmitted by IAM, GMSC can create a media gate for the ISDN user plane. For outgoing (incoming) traffic, the TSC requires one for each controlled media gate. Code. Used for the selected media gate, the TSC must use an OPC; according to the selected OPC, the transfer switch can distinguish the ISDN user plane received from different MGWs. Receive or send the user plane to different MGWs. Another alternative solution is to use different signaling routes between the servers, if the user plane is routed via different MGWs. From / to the transfer switch receives or sends the user plane to different MGWs and from / A third alternative example of server-controlled signaling is to use different GICs for different MGWs, provided that the user is routing via different MGWs. The concept of identifying the originating media by using the OPC used in the IAM information to replace the transmission media. The concept of the gateway address in the IAM information is also feasible through the entire CN, but it is necessary to control the MGWs in each control server. A different point code is used for the network of m MGWs. Another alternative solution for transmitting the knowledge of media gateway from one server to another server is to use different routes for signaling, if the user is to route to different MGWs. If the TSC can receive calls from m MGWs, then m different signalling lines need to be directed to the RNC. In the description of the different figures below, different signal names are used, and some of these signals are known in nature.

Description of Invention (24) Mobile Service Exchange Center MSC1, the mobile service switching center MSC1 then instructs the radio network controller RNC1 to establish a user-side connection towards the media gateway MGW1 and commands the media gateway MGW1 to pass the connection, followed by the action of the mobile service switching center. The radio network controller RNC2 establishes a user-side connection towards the media gateway MGW1. The second alternative commands the radio network controller to connect and does not require a media gateway connection and is only feasible for action-to-action situations. The third alternative Example, originating clearing house Take the media gateway MGW1 and forward the media gateway MGW1 address and ISUP IAM information to the mobile service switching center MSC2 of the mobile service switching center. This alternative can be optimized by combining it with the first alternative. So If the media gateway address is received in the backward direction, the mobile service switching center MSC 1 can perform the next designation towards the radio network controller RNC1. Under the third alternative, the optimization situation is not described. &Amp; To replace the GMSC2, which is the gateway to the UE in the GMSC, then it must include several GMSCs. In this example, only one media gateway is used, which can be used by all control servers to affect users. When the terminal is unknown, the transcoder is connected by the originating MSC.
