Embodiment Construction

[0014] At present, it is known that an aggregated maximum bit rate (AMBR) is often used for resource allocation in unicast technology. Currently, AMBR is defined as follows:

[0015] Multiple Evolved Packet System (EPS) bearers of the same user equipment (UE) share the same AMBR. That is, each of these EPS bearers can potentially utilize the entire AMBR, eg when the other EPS bearers do not carry traffic. AMBR limits the aggregate bit rate expected to be provided by EPS bearers sharing AMBR, for example, excess traffic can be discarded. AMBR applies to all non-guaranteed bit rate (GBR) bearers for the UE. GBR bearers are out of the scope of AMBR.

[0016] Since each evolved multimedia broadcast multicast service (e-MBMS) EPS bearer can be a non-GBR bearer, the definition of AMBR can be extended to MBMS. In the above conventional techniques, AMBR is determined for the UE. However, according to the present invention, AMBR is determined for e-MBMS services. Correspondingly,...

Abstract

The invention provides a method for carrying out statistic multiplexing in an evolution multimedia broadcast multicast service (e-MBMS) system, including: ensuring statistic multiplexing set and statistic multiplexing set information aiming at the service at a broadcast multicast service center (BM-SC); establishing an evolution grouping system (EPS) of the service to support at a gateway, and ensuring the AMBR set supported by the EPS and the AMBR set information according to the statistic multiplexing set information at the BM-SC; and dispatching the service at the base station (eNB) according to the AMBR set information ensured at the gateway, thereby distributing a plurality of service shares belonging to the same AMBR set to the resources of the set.

Description

technical field [0001] The present invention relates to the field of mobile communication, and in particular relates to an evolved multimedia broadcast multicast service system and a method thereof capable of performing statistical multiplexing by utilizing the aggregate maximum bit rate. Background technique [0002] Nowadays, with the rapid development of mobile technology, a large number of multimedia services emerge. For some of these application services, multiple users can receive the same data at the same time, such as video on demand, TV broadcasting, video conferencing, and mobile TV. In order to effectively utilize mobile network resources, the WCDMA / GSM global standardization organization 3GPP has proposed Multimedia Broadcast Multicast Service (MBMS) / Evolved Multimedia Broadcast Multicast Service (e-MBMS). MBMS / e-MBMS refers to a point-to-multipoint service in which one data source sends data to multiple users to realize network resource sharing. MBMS / e-MBMS de...
