Description

Method and device for service scheduling

technical field

The invention belongs to the communication field, and in particular relates to a service scheduling method and device.

Background technique

Mobile communication technology has developed rapidly in recent years. From the second-generation mobile communication system that is currently being widely used to the mature and perfect third-generation mobile communication system, technological development is increasingly meeting the needs of users for communication systems. Various services It also came into being. Digital trunking is a channel sharing mobile communication technology. Digital trunking calls are connected quickly, using half-duplex communication, and can support trunking services such as single call, group call, and broadcast call. Digital trunking can enable users in a group to share channels, effectively utilize frequency resources, effectively utilize network resources, and reduce construction and operation costs.

In the digital trunking system, the priority of the trunking service is divided into two levels: call priority and talk right priority. The priority should include several levels. High-priority calls have priority over low-priority calls to obtain system resources. The call priority mentioned in the current national standard includes three aspects: call establishment priority, call reservation priority, and preemption priority.

Call establishment priority means that when a call is established, the high-priority call will obtain system resources prior to the low-priority call.

Call reserve priority means that the call reserve capability is used to protect the call from being forcibly removed by the system after the call is established; the lower the call priority, the lower the corresponding call reserve capability. When the system needs to remove resources, The system will forcibly tear down the call with the lowest priority.

The preemptive call is a call with a high priority. When the system is busy, in order to ensure that the preemptive call obtains enough system resources to continue its connection process, the system will forcibly release the call with the lowest priority (forced release); when the user is in In the low-priority call, if there is a user with pre-emption priority at this time, the system will remove the user from the original low-priority call and set up a call for the user with pre-emption priority (barge in). It can be seen that the call priority issues involved in the current national standard are priority issues when the system is busy and resources are insufficient.

In the current system, the system provides increasingly rich services, such as: ordinary call service, packet data service, circuit data service, etc. When a user is in the communication process of a certain service, if the user has other service calls, Then the system will automatically reject the latter call. The prior art does not provide a solution to the problem of how to perform scheduling when the same user needs to participate in multiple services.

Contents of the invention

Detailed ways

In order to better describe the technical solution of the present invention, the specific implementation process of the present invention will be described in detail below in conjunction with the accompanying drawings.

The method and device for service scheduling proposed by the embodiments of the present invention pre-set the priorities of different services subscribed by the called user terminal in the communication system, and the priority information can be stored in the contracting entity on the network side. When the calling user terminal is in the current service communication process, if there is a new service request to access the called user terminal, the system side judges whether the priority of the new service is higher than the priority of the current service of the called user terminal, and if so, Then the called user terminal terminates the current service, otherwise, rejects the new service request and continues the current service.

As shown in Figure 1, the overall flow chart of the service scheduling method proposed by the embodiment of the present invention, it should be noted that the priorities of various services subscribed by the called user terminal need to be preset, and the priorities can be stored in the switching center Or in the home location storage, which can be set by the user through the user terminal itself, or can be set by the network side; this embodiment specifically includes the following steps:

Step 101, the network side receives a new service establishment request;

The new service establishment request may be initiated by the calling user terminal or by the network side.

Step 102, the network side judges whether the priority of the new service is higher than the priority of the current service according to the priority information of the services signed by the called user terminal;

After receiving the new service establishment request, the network side obtains the priority information of the new service signed by the called user terminal and the priority information of the current service of the called user terminal according to the subscription information of the called user terminal , comparing the priority of the two services, if the priority of the new service is higher than the priority of the current service, then send a new service indication to the called user terminal, then go to step 103, otherwise go to step 104; of course, it is also possible here It is set that when the new service priority is equal to the current service priority, it also proceeds to step 103, which is carried out according to system presets here, without affecting the implementation of this embodiment; here, it can be preset that when the called user terminal is idle has the lowest priority.

In addition, after receiving the new service establishment request, the network side may not immediately acquire the priority information of the new service signed by the called user terminal and the priority information of the current service of the called user terminal, but first Judging whether the called user terminal is currently in a busy state, if it is in a busy state, then obtain the priority information of the new service signed by the called user terminal and the priority information of the current service of the called user terminal, and compare the two The level of business priority, and then perform corresponding operations; if it is idle, directly establish a connection for the new business.

Step 103, the called user terminal terminates the current service and establishes the new service connection;

When receiving the new service instruction, the called user terminal releases the current service connection, establishes the new service connection with the network side, and ends the procedure.

It should be noted that when the called user terminal receives a new service indication, it may release the current service connection first, and then establish a new service connection; it may also first establish a new service connection, and when the new service connection is established, Then release the current service connection.

Or, after receiving the new service instruction, the called user terminal can also display the new service information to the user, and the user can choose whether to receive the new service, which can increase the flexibility of control. The specific implementation will be in A more detailed description follows.

Step 104, rejecting the new service establishment request and continuing the current service;

When the priority of the new service is relatively low, the network side may directly reject the new service establishment request according to settings.

Below we will specifically describe the implementation method of the present invention in the trunking communication system. In the trunking system, a user can belong to multiple different groups and can participate in multiple services, such as: group call service, point-to-point call service, Broadcast service, temporary group call service, temporary broadcast call service, CDMA1X call, emergency call, etc., each service has its own priority.

Fig. 2 shows the first embodiment of the present invention in the cluster system, comprising the following steps:

Step 201, the trunking switching center sends a new service instruction to the called user terminal;

When the trunking switching center receives the new service establishment request from the calling user terminal to the called user terminal, according to the method described in step 102, it can directly judge the current state of the called user terminal, if it is in an idle state, then Directly establish a connection for the new service, if it is in a busy state, you need to obtain the priority information of the new service and the current service, and make a judgment; you can also directly obtain the new service and the current service without judging the status of the called user terminal. The priority information of the service, if there is no current service, the priority information is empty; here we assume that the current called user terminal is in a busy state, and the priority of the new service is higher than the priority of the current service.

The new service indication sent by the trunking switching center carries the priority judgment result, the calling user terminal number or group number.

Step 202, the called user terminal sends a release current service request to the trunking switching center;

After the called user terminal receives the new service instruction, the called user terminal can automatically terminate the current service, and send a request to release the current service to the trunking switching center; it can also be after the called user terminal receives the new service instruction, The new service is displayed to the user for the user to choose whether to interrupt the current service and establish a new service. If the user chooses to establish a new service, the called user terminal sends a request to release the current service to the trunking switching center.

In steps 203-204, the trunking switching center sends an instruction to release the current service to the called user terminal; after releasing the resource occupied by the current service, the called user terminal sends a release completion message to the trunking switching center.

Step 205, the called user terminal sends a new service establishment request to the trunking switching center;

After releasing the current service, the called user terminal automatically initiates a request for establishing a new service, which carries information such as group number, call type, and call direction.

In steps 206-207, the Virtual Chassis Center allocates resources for the new service and establishes a new service connection. This process is the same as the prior art and will not be repeated here.

It should be pointed out that in the above method, when the called user terminal completes resource release and sends a release completion message to the cluster switching center, it may not send a new service establishment request, but the called user terminal obtained by the cluster switching center The terminal information directly establishes a connection for the new service and allocates resources for it, that is, step 205 can be omitted.

The above is the first embodiment of the present invention in the trunking communication system. Below we will introduce the second embodiment of the present invention in the trunking communication system in detail, as shown in FIG. 3 , including the following steps:

Steps 301-304 are completely the same as the above-mentioned steps 201-204, and will not be repeated here.

Steps 305-306, the trunking switching center sends a paging message to the called user terminal;

After receiving the current service resource release completion message sent by the called user terminal, the trunking switching center directly sends a paging message to page the user, allocate resources for the new service and establish a connection.

In this embodiment, the called user terminal does not need to initiate the establishment process again, and the trunking switching center directly performs paging to establish a new service connection.

In the first and second embodiments, when the called user terminal receives a new service indication, it first releases the current service, and then establishes a connection for the new service; A new service connection is created, and then the current service connection is released, which will be described in detail in the third embodiment below.

The third embodiment in the cluster system that the present invention proposes is shown in Figure 4, comprises the following steps:

Step 401, the trunking switching center sends a new service instruction to the called user terminal;

When the trunking switching center receives a new service establishment request for a certain called user terminal, according to the method described in step 102, it can directly judge the current state of the called user terminal, if it is idle, then directly If the new service establishes a connection, if it is in a busy state, it is necessary to obtain the priority information of the new service and the current service and make a judgment; it is also possible to directly obtain the priority information of the new service and the current service without judging the state of the called user terminal. Priority information, if there is no current service, the priority information is empty; here we assume that the current called user terminal is in a busy state, and the priority of the new service is higher than that of the current service.

The new service instruction sent by the trunking switching center carries the priority judgment result, the calling user terminal number or group number.

Step 402, the called user terminal sends a new service establishment request to the trunking switching center;

After the called user terminal receives the new service indication, the called user terminal can send a new service establishment request to the trunking switching center; the called user terminal can also display the new service to the user for the user to choose whether to establish the new service, If so, the called user terminal sends a new service establishment request to the trunking switching center.

In steps 403-404, the trunking switching center receives a new service establishment request, allocates new resources for the called user terminal, and establishes a new service connection.

Step 405, the called user terminal initiates a request to release the current service;

After the new service is established, the called user terminal sends a request to release the current service to the mobile switching center.

In steps 406-407, the current service connection is released, and the occupied resources are released.

In the third embodiment above, after receiving the new service establishment instruction, the called user terminal first establishes the new service, allocates resources for the new service, and then releases the current service connection, so that the call failure can be reduced. rate, resulting in a better user experience.

The embodiment of the present invention also proposes a service scheduling device, as shown in Figure 5, including:

Message receiving module 501: for receiving the service establishment message sent by the called user terminal;

Priority judging module 503: According to the new service establishment request sent to the called user terminal received by the message receiving module, judge whether the priority of the new service is higher than the priority of the current service of the called user terminal, and Send the judgment result to the business scheduling module;

Service scheduling module 504: used to receive the priority judgment result sent by the priority judgment module, if the priority of the new service is higher than the priority of the current service of the called user terminal, send an operation to the message sending module Instruct, instruct the called user terminal to release the current service and establish the new service connection, or instruct the called user terminal to establish a new service connection, and release the current service after the new service connection is established; otherwise, reject the new service establishment ask;

Message sending module 505: used to send a message to the called user terminal, instructing the called user terminal to establish or release a service connection.

The service scheduling module 504, when receiving a new service priority higher than the current service priority, sends an operation instruction to the message sending module 505, which may first instruct the called user terminal to release the current service, and then instruct the called user terminal to release the current service. The terminal establishes a new service connection; it may also first instruct the called user terminal to establish a new service connection, and then instruct the called user terminal to release the current service.

At the same time, the service scheduling device may also include a user status judging module 502, as shown in FIG. 6, for judging the current status of the called user terminal according to the new service establishment request received by the message receiving module. In the idle state, send a message to the service scheduling module to instruct the called user terminal to establish the new service connection; otherwise, send the service establishment request to the priority judging module.

Through the service scheduling method and device proposed by the embodiment of the present invention, when the user is in a low-priority service, if another high-priority service is received, the network side can automatically withdraw the user from the low-priority service and enter the high-priority service. Priority services, which can ensure that the same user's high-priority services are executed as soon as possible. Further, when the called user terminal has a service request with a higher priority than the current service, it can display the new service request to the user for the user to choose whether to receive the new service, which increases the flexibility of selection , which solves the scheduling problem when the same user has multiple services that need to participate.

The specific embodiments described above have further described the purpose, technical solutions and beneficial effects of the present invention in detail. It should be understood that the above descriptions are only specific embodiments of the present invention and are not intended to limit the present invention. , Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present invention shall be included within the protection scope of the present invention.
