Method and system for acquiring business status information

technical field

The present invention relates to information communication technology, in particular to a method and system for acquiring service state information. the

Background technique

Multimedia Broadcast/Multicast Service (MBMS for short) is a technology that shares network resources and transmits data from one data source to multiple targets. In order to provide multimedia services and effectively utilize mobile network resources, the first The 3rd Generation Partnership Project (3rd Generation Partnership Project, referred to as 3GPP) protocol proposed the multimedia broadcast/multicast service MBMS in Release 6 (Release6, referred to as R6). MBMS provides a point-to-multipoint service in which a data source sends data to multiple users in a mobile network to realize network resource sharing. the

In the existing network structure, the transmission of MBMS generally adopts the method of polling access at regular intervals to carry out the statistics of the number of users. Corresponding network resources and service transmission, and then allocate the required wireless resources according to the service quality, and send the MBMS service data to the broadcast/multicast service center (Broadcast/Multicast Service-Center, BM-SC for short), and the BM-SC transmits the data forwarded to the bearer layer of MBMS. In this way, MBMS data can be sent down to all user terminals joining the MBMS service. the

There are the following defects in the polling method of user statistics in existing network services:

1) It is necessary to query users who use this service at regular intervals, and the network usage efficiency is low;

2) The downlink mechanism of regular polling is not conducive to the operator's business adjustment and flexible configuration of network resources;

3) Because polling needs to occupy certain resources, the overhead of network resources and air interface physical resources is relatively large;

4) There is a problem of time inconsistency between user service feedback and use. the

Contents of the invention

The purpose of the present invention is to provide a method and system for obtaining business status information, aiming at the defects of large waste of network resources, low efficiency and inflexible business configuration caused by the business transmission mode of polling and delivering business data in the prior art. It can realize the adjustment and control of services and the flexible configuration of network resources, save network resources to the greatest extent, reduce the overhead of network resources and air interface physical resources, and improve the efficiency of network use. the

In order to achieve the above object, the present invention provides a service state information acquisition method, comprising: the broadcast multicast service center BM-SC receives the uplink feedback information containing the service usage information sent by the user terminal (User equipment, referred to as UE) based on event triggering, According to the uplink feedback information, the business usage status information is obtained and sent to the multimedia broadcast multicast coordination entity (MBMS coordinating entity or Muti-cell/Muticast coordination entity, MCE for short). The resources are configured and the business data is sent to the user terminal. the

Before the broadcast and multicast service center BM-SC receives the uplink feedback information containing service usage information sent by the user terminal based on the event trigger, it includes: the user terminal triggers a certain service event; sending the uplink feedback information containing the triggered service event information; The base station receives the uplink feedback information, and feeds back the information through the Long Term Evolution (LTE for short) network, the second generation mobile communication network (2nd Generation, 2G for short) or the third generation mobile communication network (3rd Generation, 3G for short). Go to the broadcast and multicast service center BM-SC. the

The user terminal sending the uplink feedback information containing the service usage information may include: adding the triggered service event and the service identification information to be used to the uplink feedback information; it may also include: adding the user location, feedback type, and feedback mode information to the Uplink feedback information: the user terminal sends the uplink feedback information. The user location is used to feed back the location information of the user; the feedback type indicates the type of feedback information; the feedback measure indicates the quantity information of the feedback information. the

In order to achieve the above object, the present invention also proposes a service state information acquisition system, including a broadcast multicast service center, a base station, a user terminal, and a multimedia broadcast multicast adjustment entity, wherein:
