Embodiment Construction

[0090] Preferred embodiments of the present invention will be described below with reference to the accompanying drawings. in the description below

[0091] In , known functions or structures will not be described in detail.

[0092] Figure 6 Based on the LTE core network, a new network unit BM-SC is added to the MBMS network structure. 601 with figure 1 The description is the same as that of the MBMS system, which is the service control center of the MBMS system. 602 and 603 respectively with Figure 5 The network nodes 502 and 503 in are the same. The function of the ECN is to initiate the establishment and release of the bearer, route the MBMS data to the appropriate downstream node equipment, and indicate the MBMS function support to the UE. The function of ERAN is to effectively transmit MBMS data to the designated MBMS service area, MBMS paging, and support parallel services with MBMS.

[0093] In the MBMS network structure, the basic process of UE joining MBMS ser...

Abstract

A method for supporting MBMS data transmission in an LTE system comprises the following steps: when an MBMS conversation is established, a BM-SC sends an 'MBMS Conversation Establishment Request' to an ECN (ECN (M)) providing an MBMS service; the ECN providing the MBMS service sends an 'MBMS Conversation Establishment Response' to the BM-SC, and sends an 'MBMS Conversation Establishment Request' to the ECN registered by UE; the ECN registered by UE sends an 'MBMS Conversation Establishment Response' to the ECN providing the MBMS service; the ECN registered by UE sends an 'MBMS Conversation Establishment Request' to an ERAN; the ERAN sends an 'MBMS Conversation Establishment Response' to the ECN registered by UE; and the ERAN establishes an essential wireless resource for transmitting MBMS data. The invention provides a new method for providing wireless source management device with MBMS UE context, simplifies a signaling flow and improves the efficiency.

Description

[0001] This application is a divisional application of Application No. 200610001694.6 entitled "Method for Supporting MBMS Service Transmission in LTE System" submitted to China Patent Office on January 24, 2006. technical field [0002] The present invention relates to a method for supporting MBMS service transmission in a mobile communication system long-term evolution (hereinafter referred to as LTE) system proposed by the Third Generation Partnership Project (hereinafter referred to as 3GPP). Background technique [0003] figure 1 The MBMS system structure is described. The MBMS network structure is based on the general packet radio service (GPRS) core network, and a new network unit is added. Below is the right figure 1 Description of MBMS system structure. [0004] 101 The broadcast and multicast service center (BM-SC for short) is the service control center of the MBMS system. 102 Gateway GPRS Support Node (GGSN for short) and 103 Serving GPRS Support Node (SGSN fo...
