Description

Method and system for obtaining state information based on multimedia broadcast multicast service

technical field

The invention relates to a Multimedia Broadcast and Multicast Service (Multimedia Broadcast and Multicast Service, hereinafter referred to as: MBMS) technology, which belongs to the field of mobile communication. the

Background technique

Multimedia Broadcast and Multicast Service (MBMS) is a technology that transmits data from one data source to multiple user equipments by sharing network resources. In order to provide multimedia services and effectively utilize mobile network resources, The 3rd Generation Partnership Project (3rd Generation Partnership Project, referred to as 3GPP) agreement proposed the multimedia broadcast multicast service MBMS in the version 6 (Release6, referred to as R6). MBMS provides a point-to-multipoint service in which a data source sends data to multiple user equipments in a mobile network, so as to realize network resource sharing. the

In the existing network structure, the transmission of MBMS generally adopts the method of polling and accessing at regular intervals to carry out statistics on the number of users. Allocate the 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 (BM-SC for short), and the BM-SC forwards the data to The bearer layer of MBMS. In this way, MBMS data can be sent down to all user terminals joining the MBMS service. the

The defective of prior art is:

1. The polling mechanism is very inefficient for acquiring user equipment status information. This is because no matter how many UEs are in the area, the system needs to perform polling statistics periodically, which takes up a lot of system resources. the

2. The system cannot obtain service information and application information at the same time. Wherein, the service information refers to whether a certain UE has subscribed to the MBMS service; the application information refers to whether a certain UE is running a certain application service, for example, whether it is watching video files online or not. Since not all UEs in a certain area that have activated MBMS services are running application services at the same time, the system cannot obtain the above two kinds of information at the same time through periodic polling statistics, making the network unable to optimize the network according to the user's service needs resources, and cannot recommend services for non-application business users. the

Contents of the invention

The problem to be solved by the present invention is: the efficiency of obtaining the state information of the user equipment by adopting the polling mechanism is very low, wastes system resources and cannot obtain service information and application information at the same time. the

In order to solve the above problems, an embodiment of the present invention provides a method for acquiring status information based on multimedia broadcast multicast services, which is characterized in that it includes:

After the user equipment detects the event trigger, the base station node in the area sends the uplink feedback signaling carrying the state information of the user equipment to the coordination entity in the area;

The coordinating entity reallocates network resources for all user equipments in the area according to the uplink feedback signaling. the

In order to solve the above problems, another embodiment of the present invention is to provide a multimedia broadcast multicast service system, including: user equipment, base station node and coordination entity, wherein,

The user equipment is used to send the uplink feedback signaling carrying the status information of the user equipment after detecting the event trigger;

The coordination entity is used to send resource management signaling to the base station node in the area according to the uplink feedback signaling from the base station node;

The base station node is configured to send the uplink feedback signaling from the user equipment to the coordinating entity, and reallocate network resources for the user equipment in the area according to the resource management signaling from the coordinating entity. the

Through the present invention, when an event is triggered, the user equipment actively sends uplink feedback signaling to realize the allocation of network resources, so that it is not necessary to periodically use the polling mechanism to count and count the user equipment, which improves the operating efficiency of the system and saves System resources occupied by periodic polling are reduced. the

In addition, because the uplink feedback signaling carries the status information of the user equipment, the system can simultaneously obtain relevant information such as whether all user equipments in a certain area have subscribed to the MBMS service and whether they are running the application service of the MBMS service, that is, Service information and application information can be obtained at the same time. the

Detailed ways

Example 1

This embodiment provides a method for obtaining state information based on MBMS, as shown in Figure 1,

Step 101, after the user equipment detects an event trigger, it sends an uplink feedback signaling carrying the state information of the user equipment to a coordinating entity (MBMS Coordinating Entity, MCE for short) in the area where it is located. Specifically, the user equipment may send the uplink feedback signaling to the coordination entity through the base station node in the area where it is located. the

Wherein, the user equipment usually refers to a wireless terminal supporting MBMS technology. The coordinating entity refers to a network entity for coordinating and managing network resources. The event triggering means that the user equipment detects that the service application of MBMS on the user equipment is started, the service application is terminated or the service application is switched. For example, the service application is to play video online, and the service application is started when the user equipment starts to play the video online; the service application ends when the video playback stops. In addition, in addition to the opening and closing of business applications, other operations on business applications can also be used as conditions for judging event triggers, for example, users change channels to watch, or the network can also pre-specify that users are required to trigger feedback messages when performing certain services. make. Specifically, the state information of the user equipment carried in the uplink feedback signaling may be used to indicate that certain events in the user equipment in the current state are triggered. the

Step 102, the coordinating entity reallocates network resources for all user equipments in the local area according to the uplink feedback signaling. Specifically, the coordinating entity may first send resource management signaling to the base station node where the user equipment is located, and then the base station node re-allocates network resources for all user equipment in the area where the user equipment is located according to the resource management signaling; or, the coordinating entity may also The resource management signaling may be sent to a group of base station nodes controlled by it first, and then the group of base station nodes reallocate network resources for all user equipments in the area according to the resource management signaling. Wherein, the base station node may be a base station in a network structure based on the LTE standard, that is, an Evolved Universal Terrestrial Radio Access Network node (Evolved Universal Terrestrial Radio Access Network, referred to as E-UTRAN Node B, or may also be referred to as eNodeB). resource management. the

Wherein, the uplink feedback signaling carries status information of the user equipment, and the status information indicates that certain events in the current status of the user equipment are triggered. For example, the user equipment stops playing video online, the network resources of the user equipment are released, and the coordinating entity can reallocate the network resources to other user equipments according to the uplink feedback signaling, so as to optimize resource allocation. the

Through the method described in this embodiment, when an event is triggered, the user equipment actively sends uplink feedback signaling to realize the allocation of network resources, so that there is no need to periodically use the polling mechanism to count and count the user equipment, which improves the operation of the system. Efficiency, and save system resources occupied by periodic polling. the

In addition, because the uplink feedback signaling carries the status information of the user equipment, the system can simultaneously obtain relevant information such as whether all user equipments in a certain area have subscribed to the MBMS service and whether they are running the application service of the MBMS service, that is, Service information and application information can be obtained at the same time. Thereby, it is beneficial to enable the network to optimize network resources according to the user's service requirements, and can also recommend services to users who have not applied the service. the

Example 2

The method described in Embodiment 1 is implemented based on the signaling of the control plane, but the signaling is run inside the system, and the system administrator cannot know the running status of the signaling. In order to solve this problem, this embodiment provides another A method for acquiring state information based on MBMS, as shown in Figure 2,

Steps 101 and 102 are the same as the corresponding steps in Embodiment 1, and will not be repeated here. the

Step 103, after the coordinating entity reallocates network resources, it sends service feedback information to the Broadcast Multicast Service Center (BM-SC for short), which is used to provide resource allocation results to the BM-SC. the

Step 104, the broadcast multicast service center displays query information according to the received service feedback information, and is used to query the network administrator whether to control the allocation of network resources. If the network administrator wants to control the allocation of network resources, the BM-SC can send a resource allocation instruction to the coordination entity. the

Step 105, the coordinating entity reallocates network resources for all user equipments in the area according to the resource allocation instruction. For the specific distribution method, refer to step 102, which will not be repeated here. the

Through this embodiment, since the coordinating entity provides the resource allocation result to the BM-SC after reallocating the network resources, the result is different from the signaling, it can be displayed in the form of a message, so that the network administrator can know through the BM-SC To the current state of network resource allocation, so that the network administrator can control the allocation of network resources, increasing the means of network resource allocation and the controllability of the system. the

Example 3

This embodiment provides a multimedia broadcast multicast service system, as shown in FIG. 3 , including a coordinating entity 10, a plurality of base station nodes such as a base station node 20, and a plurality of user equipment such as a user equipment 30. The following takes the user equipment 30 as an example to initiate uplink feedback to illustrate the working process of the MBMS service system. the

After the user equipment 30 detects the event trigger, it sends the uplink feedback signaling carrying the state information of the user equipment to the base station node 20 in the area. the

Wherein, the user equipment 30 generally refers to a wireless terminal supporting MBMS technology. The event triggering means that the user equipment 30 detects that the service application of MBMS on the equipment is started or the service application is terminated. For example, the service application is to play video online, and the service application is started when the user equipment 30 starts to play the video online; the service application ends when the video playback stops. Specifically, the state information of the user equipment 30 carried in the uplink feedback signaling may be used to indicate that certain events in the user equipment in the current state are triggered. the

The base station node 20 sends the uplink feedback signaling from the user equipment 30 to the coordinating entity 10 . Wherein, the coordinating entity 10 refers to a network entity for coordinating and managing network resources. the

After receiving the uplink feedback signaling, the coordinating entity 10 sends resource management signaling to the base station node 20 where the user equipment 30 is located. The base station node 30 reallocates network resources for all user equipments including the user equipment 30 in the area where it is located according to the resource management signaling. the

Wherein, the uplink feedback signaling carries status information of the user equipment 30, and the status information indicates that certain events in the current status of the user equipment 30 are triggered. For example, the user equipment 30 stops playing video online, the network resources of the user equipment 30 are released, and the coordinating entity 10 can reallocate these network resources to other user equipments according to the uplink feedback signaling, so as to optimize resource allocation. the

Through the system described in this embodiment, when an event is triggered, the user equipment actively sends uplink feedback signaling to realize the allocation of network resources, so that there is no need to periodically use the polling mechanism to count and count the user equipment, which improves the operation of the system. Efficiency, and save system resources occupied by periodic polling. the

In addition, because the uplink feedback signaling carries the status information of the user equipment, the system can simultaneously obtain relevant information such as whether all user equipments in a certain area have subscribed to the MBMS service and whether they are running the application service of the MBMS service, that is, Service information and application information can be obtained at the same time. the

Example 4

The broadcast multicast service center 40 belongs to a mobile network functional entity, which is used to provide access for content providers, authorize and initiate MBMS bearer services in the mobile network, and transmit MBMS content according to a predetermined time plan. Its working principle is as follows:

In Embodiment 3, after the coordinating entity 10 re-allocates network resources for the user equipments in the area according to the uplink feedback signaling, it also sends service feedback information to the broadcast multicast service center 40 for providing resource allocation results. the

After receiving the administrator instruction from the network administrator, the broadcast multicast service center 40 sends a resource allocation instruction to the coordinating entity 10 according to the administrator instruction. Specifically, the broadcast multicast service center 40 first displays query information according to the received service feedback information, and is used to query the network administrator whether to control network resource allocation. If the network administrator decides to control the allocation of network resources at this time, the broadcast and multicast service center 40 sends a resource allocation instruction to the coordinating entity 10 . the

The coordinating entity 10 re-allocates network resources for user terminals in the area where the coordinating entity 10 is located according to the received resource allocation instruction from the broadcast multicast service center 40 . For the specific allocation method, please refer to step 102 in Embodiment 1, that is, the reallocation of network resources can be performed only to the user equipment in the area where the base station node 20 is located; or to a group of base station nodes or all The user equipment corresponding to the base station node performs reallocation of network resources. the

Through this embodiment, since the coordinating entity 10 also provides the resource allocation result to the BM-SC after redistributing the network resources, the result is different from signaling and can be displayed in the form of a message, so that the network administrator can pass the BM-SC Knowing the current network resource allocation status enables the network administrator to control the allocation of network resources, increasing the means of network resource allocation and the controllability of the system. the
