Embodiment Construction

[0034] Embodiments of the present invention will be described below with reference to the drawings. figure 1 is a schematic diagram illustrating a system configuration according to an embodiment of the present invention, in which the same reference numerals are assigned to the same components as shown in FIGS. 7 to 9 . from figure 1 It can be seen that the core network (CN) 10 includes an MSC 11 (defined as a CS domain) with a circuit switching function for voice communication and an SGSN with a packet switching function for packet data communication [in the service of GPRS (General Packet Radio Service ) support node] 12 (defined as PS domain). The SGSN 12 can be used for the existing packet service as well as the previously described new MBMS service (broadcast or multicast communication service supporting data communication at a higher speed than the packet service), and the mobile terminals 51 and 52 can be used for both services as well.

[0035] These mobile terminal...

Abstract

To eliminate competition with another packet communication service when constructing a logic connection in an Iu interface required for providing a service corresponding to a high speed data communication called MBMS in a mobile communication system. As a logic connection between an SGSN of a CN and a radio control device, a connection for a PS (packet exchange processing) function for an existent packet communication service and a connection for an MBMS service which is a novel high speed data communication are independently and separately arranged. Thus, there is no competition between different kinds of services such as a PS service and an MBMS service, and processing between the different kinds of services is performed without caring of mutual processes. Further, opening processing of a connection is singly performed for each service, so that complexity in processing of the SGSN is eliminated.

Description

technical field [0001] The present invention relates to a mobile communication system, a method of controlling its operation and nodes used in the system, and more particularly to a system for configuring signaling connections on an interface between a core network and a radio network controller (RNC) , the signaling connection is essential when providing a broadcast or multicast service supporting high-speed data communication called MBMS (Multimedia Broadcast Multicast Service) in a mobile communication system. Background technique [0002] In the "RRC service provided to the upper layer" in Chapter 5 of the specification TS 25.331 (non-patent document 1) formulated by 3GPP (Third Generation Cooperation Project), it is defined that the configuration can be used in W-CDMA (Wideband CDMA) mobile communication system The technology of the signaling connection of the transmission control of various control signals. The signaling connection configuration technique is described...
