Resource allocation method, device and base station for concurrent terminal services

technical field

The present invention relates to the technical field of wireless communication, in particular to a resource allocation method, device and base station for concurrent services of terminals.

Background technique

VoLTE (Voiceover LTE) is the final evolution solution of LTE (Long Term Evolution, Long Term Evolution) voice, that is, to carry voice on IP and use LTE network for transmission. Under VoLTE, due to the introduction of network elements such as IMS (IP Multimedia Subsystem, which is an IP multimedia subsystem, which is a brand-new multimedia service form) and PCRF (Policy and Charging Rules Function, policy and charging rule functional unit), different The QoS (Quality of Service, quality of service) of the business is distinguished. Voice and different types of data services belong to different QCIs (QoSClassIdentifier, which is a scale value). The network schedules relevant resources for the UE (user terminal) according to the QCI priority to ensure that users call and Internet needs.

With the popularization of smart phones, the influence of background services of smart phones (that is, data services running in the background) on the network is gradually increasing. In real life, many applications need to interact with the network side to update relevant data (such as QQ, WeChat etc.), and the process does not end when the user exits the app. When there are many applications installed on the mobile phone, the signaling records show that the mobile phone may initiate a service every 1 to 2 minutes. Even though the actual exchanged information is very little, it occupies a certain proportion of signaling and service channel overhead. In some cases, it will degrade the experience of other users.

In LTE, users can perform several services concurrently, but in actual voice or video calls, users usually do not have the demand for data services at the same time (for example, many users use mobile phones on the ears during calls, and basically do not have access to the Internet. demand; and there is generally no screen space for Internet access during video calls); and the current mobile phone manufacturers’ optimization plan for background services is to pack multiple heartbeat packets and upload them at a cycle of 10 seconds, but in TD-SCDMA (Time Division Synchronization Code In TD-LTE (time-division long-term evolution), the radio resource timer of the air interface generally exceeds 10 seconds. In this case, the terminal will remain connected. In addition, eNodeB (EvolvedNodeB, namely evolved NodeB Referred to as eNB, the name of the base station in LTE) there is no specific resource allocation algorithm for concurrent services. When the user performs voice and data services at the same time, the base station will schedule two required resources for the terminal. In this case, the network capacity A relatively tense hotspot area may cause network congestion, thereby affecting the quality of user communication and affecting user experience.

detailed description

In order to make the object, technical solution and advantages of the present invention clearer, the present invention will be described in detail below with reference to the accompanying drawings and specific embodiments.

The present invention aims at that in an LTE network, when a user conducts voice and data services at the same time, the base station will schedule two types of required resources for the terminal. In this case, network congestion may be caused in hot spots where the network capacity is relatively tight. To solve the problem that user communication quality is affected and user experience is affected, a resource allocation method, device and base station for terminal concurrent services are provided.

As shown in FIG. 1, the resource allocation method for the terminal concurrent service in the embodiment of the present invention includes:

Step 10, when receiving the first service request of the terminal, detecting whether at least one second service request of the terminal is being processed;

Step 20, if it is detected that the second service request of the terminal is being processed, then judge whether the network where the terminal is located is in a congested state;

Step 30, if the network is in a congested state, limit resource allocation for the second service request, and process the first service request.

It should be noted that the present invention is mainly aimed at realizing the transmission of voice in the LTE network (the voice is carried on IP and transmitted using the LTE network). A voice call request or a video call request, the second service request is a data service request of the terminal under the LTE network, and the data service request can be an update of data, such as an update of dialogue reminders such as QQ, WeChat, etc.; it can also be a resource download, such as buffering of video data, etc.

In the above solution of the present invention, when a voice or video call request is received during data service processing, the allocation of resources requested by the terminal service is adjusted according to actual needs, concurrent data services are limited, and sufficient resources for voice or video requests are ensured Allocation, this method ensures the quality of voice calls, improves the utilization of wireless resources, and alleviates network congestion.

Here, it should be noted that in the LTE network, the 3GPP protocol specifies 9 QCIs to indicate the QoS requirements of different services, as shown in Table 1, such as QCI5 carrying IMS signaling, QCI1 carrying VoLTE voice calls, QCI2 Carries video calls, QCI3 carries real-time game services, and QCI4 carries non-in-session video services.

Table 1 Definition of different QoS in LTE

By defining the resource requirements of different services (delay, packet loss rate, etc.) The channel between the core network and the core network), the core network allocates core network resources to the user, and at the same time identifies the QCI of the UE as 1, and notifies the eNodeB through the S1 port (that is, the port for establishing a connection between the core network and the eNodeB), and the eNodeB uses the QCI QoS = 1 requires scheduling corresponding radio resources to the UE.

When the user is making a VoLTE voice and video call on the LTE side, if there is concurrent data service at the same time, the UE initiates the ModifyEPSbearercontextrequest (request to modify the content carried by the evolved packet system) process, and the core network side will create a voice service QCI for the user , while retaining the original QCI, and then the core network sends an ERABModifiedRequest (channel modification request) to the S1 port connected to the base station to update the QoS of the UE.

Therefore, in this solution, the obtained QCI is mainly used to distinguish different service requests of the terminal. On this basis, in another embodiment of the present invention, the step 20 includes:

If it is detected that the second service request of the terminal is being processed, the index information for determining the congestion state is acquired, and the index information may be physical radio resource block utilization rate (ie, PRB utilization rate), or real-time scheduling times;

Comparing the index information with a preset threshold value corresponding to the index information, and obtaining a comparison result;

If the comparison result indicates that the index information is greater than or equal to the preset threshold value, it indicates that the network is in a congested state.

It should be noted that, by obtaining the measured quantities in the network, the operation status of the network can be judged in real time. This method ensures the real-time performance and accuracy of the measurement. Further, the step of judging whether the network is in a congested state is for those skilled in the art. well-known, and will not be described in detail here.

When it is judged that the network is in a congested state, if the terminal is still synchronously performing data services while making a voice call, the load on the network will increase, thereby also affecting the quality of the call. The step 30 of the embodiment of the present invention The specific implementation is: suspending at least one of the second service requests and/or reducing the number of times of scheduling and the number of allocated physical radio resource blocks for at least one of the second service requests, and then processing the first service request.

For example, when the base station is processing terminal A's WeChat message update and video resource buffer data services, at this time the base station receives a service request from terminal A to initiate a voice call, and at this time the base station determines the network (cell B) where the terminal is located In the congested state, the following schemes can be adopted to adjust the allocation of data service resources:

Solution 1: Considering that there are many network resources for buffering video resources, in this solution, the data service buffered by the video resource is suspended (that is, the buffering of the video is stopped), and the time for updating the data service of WeChat messages is reduced. Domain scheduling times (that is, reduce the frequency of updates);

Option 2: Suspend all the data services of the WeChat message update and video resource buffering;

Solution 3: Suspend the data service of WeChat message update, and at the same time reduce the number of resources (that is, the number of PRBs) allocated to the data service of the video resource buffer;

After the service request of the voice call is processed, the data service of WeChat message update and video resource buffering is resumed, that is, data resources are allocated to each data service according to the data service status before the voice call.

The above three schemes are just simple examples to limit the processing of data services. It should be noted that how to control the processing of data services in the application can be formulated according to the needs of network operators and different strategies. In the present invention, there is no need to give examples one by one.

As shown in FIG. 2 , the implementation process of the method for resource allocation of concurrent terminal services in Embodiment 2 of the present invention is specifically as follows:

Step S11, the base station receives a VoLTE voice or video call request from the user terminal;

Step S12, the base station detects whether other data services of the user terminal are being processed;

If it is detected that other data services are being processed, then proceed to step S13 to detect whether the network where the terminal is located is in a congested state; otherwise, directly allocate service resources to the voice or video call request, and process the voice or video call request;

If it is detected that the network is in a congested state, then proceed to step S14, suspend some data services or limit resource allocation to concurrent data services, and process voice or video call requests;

It should be noted that the step S14 can also be set to manual control, and the network optimization personnel enable this function for some cells with heavy loads through index analysis and other means, and can also choose to automatically adjust;

After the voice or video call request is processed, proceed to step S15 to resume normal processing of the data service;

If it is detected that the network is not in a congested state, proceed to step S16, directly allocate service resources to the voice or video call request, and process the voice or video call request.

As shown in FIG. 3 , the implementation process of the method for resource allocation of concurrent terminal services in Embodiment 2 of the present invention is specifically as follows:

Step S21, the base station is processing the data service of the user terminal;

Step S22, at the same time, the base station detects whether the user terminal has a VoLTE voice or video call request;

If it is detected that there is a voice or video call request, then proceed to step S23 to detect whether the network where the terminal is located is in a congested state;

If it is detected that the network is in a congested state, then proceed to step S24, suspend some data services or limit resource allocation to concurrent data services, and process voice or video call requests;

After the voice or video call request is processed, proceed to step S25 to resume normal processing of the data service;

If it is detected that the network is not in a congested state, proceed to step S26, directly allocate service resources to the voice or video call request, and process the voice or video call request.
