Problems solved by technology

Considering that even a city as big as Shanghai has only 2-3 RNCs, this defect is very unfavorable for attracting MBMS users, maintaining the continuity of MBMS services, and supporting personalized services for MBMS services
In addition, all users in the coverage area of ​​GERAN (GSM / EDGE RadioAccess Network) will not be able to receive MBMS services

Embodiment Construction

[0027] Referring to Fig. 1 below, a method for supporting MBMS QoS candidate sets in a mobile communication system according to a specific embodiment of the present invention is described, wherein the mobile communication system may be a UMTS (Universal MobileTelecommunication System) using CDMA technology )Access Network. :

[0028] First, in the 3G mobile communication system, for MBMS services with different QoS candidates in the MBMS service candidate set, that is, MBMS services with the same service content but different QoS, corresponding identification information, including IP multicast addresses, will be allocated in the 3G core network And related TMGI (Temporary Mobile Group Identity, temporary mobile group identity). In other words, each service in the MBMS service QoS candidate set is assigned a separate MBMS service identification number (MBMS Service ID). For example, if there are two services with the same content but different QoS levels in a certain MBMS se...

Abstract

This invention provides one device and method to provide mobile system certain MBMS business for different QoS selection and prepare device, which in detail forms MBMS business QoS prepare set according to different business definitions to inform user device. The user device selects proper QoS MBMS load business according to needed or real conditions.

Description

technical field [0001] The present invention relates to a mobile communication system, more specifically, to a network device, user equipment and method for supporting different QoS options for a certain service in multimedia broadcast multicast service (MBMS service). Background technique [0002] According to the current 3GPP protocol, in all coverage areas of each MBMS (Multimedia Broadcast Multicast Service, Multimedia Broadcast Multicast Service) service, all users can only passively receive the MBMS service according to the same quality of service (QoS, Quality of Service)[ 23.246]. Moreover, if a certain radio network controller (RNC, Radio Network Controller) or serving GPRS support node (SGSN, ServingGPRS Support Node) in the 3G network cannot meet the QoS requirements for supporting the service, the area covered by the RNC or SGSN All users of will be unable to receive the MBMS service [23.246]. Considering that even a city as big as Shanghai has only 2-3 RNCs, t...
