Problems solved by technology

However, since it is impossible to accurately summarize the complex wireless environment and user service profiles by a single parameter (i.e., the number of UEs), statistical mechanisms fail to achieve efficient radio resource allocation
Thus, the statistical mechanism suffers from inefficiency and can waste considerable power resources due to lack of any adaptation functionality

Abstract

The present invention relates to a method, a radio network controller and a wireless communication system for allocating transport channels to provide Multimedia Broadcast Multicast Service MBMS services to one or more User Equipments UEs in a cell of a wireless network, comprising: obtaining parameters including a rate required by a MBMS service and a location factor indicating location of a UE in the cell, determining power cost of providing the MBMS service to the UE for each of types of transport channels available in the cell based on at least the required service rate and the location factor, and selecting a type of transport channel that has a minimum power cost to provide the MBMS service to the UE. This improves the efficiency of power usage, overall cell throughput and service quality.

Description

technical field [0001] The present invention relates generally to the field of wireless communications, and more particularly to a method for allocating transport channels for Multimedia Broadcast Multicast Service (MBMS) and devices and systems associated therewith. Background technique [0002] It is indisputable that the future mobile market will be characterized by multimedia services requiring greater bandwidth already experienced in wired networks. Based on this situation, MBMS was introduced in R6 of UMTS (Universal Mobile Telecommunications System) in order to deliver multimedia data from a single source entity to multiple destinations. MBMS is envisioned to be critical to other rich multimedia services. Therefore, the main goal of MBMS is to efficiently provide multimedia services. [0003] A major requirement during the provision of MBMS services is efficient overall utilization of radio and network resources. That is, wireless networks providing MBMS services s...
