Description

Resource Allocation Method and MBMS System

technical field

The present invention relates to the communication field, in particular, to a method for measuring the quality of Multimedia Broadcast/Multicast Service (MBMS for short) in PTM mode and an MBMS system.

Background technique

MBMS is a technology that shares network resources and transmits data from one data source to multiple targets. In traditional mobile networks, Cell Broadcast Service (CBS) allows low bit rate data to be sent to all users through the shared broadcast channel of the cell, which belongs to the message service. In R99, only the short message service (SMS) cell broadcast service uses CBS . In order to effectively utilize mobile network resources, 3GPP proposed Multimedia Broadcast/Multicast Service (MBMS) in R6, which provides a point-to-multipoint service in which one data source sends data to multiple users in a mobile network to realize network resource sharing. Improve the utilization of network resources, especially the precious air interface resources. MBMS can not only realize plain text and low-rate message multicast and broadcast, but also realize multicast and broadcast of high-speed multimedia services, and provide a variety of rich video, audio and multimedia services, which undoubtedly conforms to the development trend of mobile data in the future. trend, providing better business prospects for the development of 3G.

MBMS has two business bearing modes, broadcast and multicast. The multicast mode requires the user to sign up for the corresponding multicast group, activate the service, and generate corresponding billing information. Since the multicast and broadcast modes have different business requirements, their business processes are also different.

In the service flow of MBMS multicast mode, the user joins the multicast group and the session start is two independent processes, that is, the user can join the multicast group at any time when the session starts and the session is in progress.

MBMS has two transmission methods: point to point (point to point, hereinafter referred to as PTP) and point to multipoint (point to multipoint, hereinafter referred to as PTM). In the PTP transmission mode, data is transmitted through a dedicated service logical channel (Dedicated Traffic Channel, DTCH), and mapped to a forward access channel (Forward Access Channel, FACH), a dedicated channel (Dedicated Channel, DCH) or a high-speed downlink shared channel (High- On SpeedDownlink Shared Channel, HS-DSCH), only one UE (User Equipment, user equipment) can receive; in PTM mode, transmit data through MBMS PTM (Multimedia Broadcast/Multicast Service point to multipoint) business channel MTCH, and map to FACH, multiple UE can receive.

When using PTM to send MBMS, the business is transmitted through the common channel. The public channel only has open-loop power control. If the initial transmit power is set too high, it will waste wireless resources and cause interference to neighboring cells. If the setting is low, since there is no feedback mechanism for the transmission quality of downlink services, when the wireless quality changes, the service quality of the services cannot be guaranteed, which cannot meet the requirements of some high-end users.

Therefore, it is necessary to provide a method for measuring MBMS service quality in PTM mode, so as to solve the above-mentioned problems in related technologies.
