Description

Priority management method in the weakened state of base station failure

technical field

The invention relates to mobile communication technology, in particular to a priority management method in the weakened state of base station failure.

Background technique

The fault weakening function of the trunking system aims to provide limited trunking services for the trunking terminals under the coverage of the base station after the base station is disconnected from the core network, at least including voice single call and voice group call services.

In the trunking system, in order to ensure the orderly scheduling and control, priority management functions are generally provided, allowing high-priority calls or users to obtain resources preferentially during call establishment and talk right preemption. For example, in the process of group call application, the core network judges the priority of the applied user, and if it is higher than the user who is speaking, then grants the speech right to the user with high priority; Call priority is assigned to the call. If multiple groups of a certain terminal have initiated calls, the terminal can access the call with higher priority by comparing the call priority.

In the existing cluster system, the core network of the system is responsible for the distribution of priority. However, for the fault-weakened state, since the connection between the base station and the core network is disconnected, neither the base station nor the terminal can obtain priority information. The "first come, first served" mechanism is mainly used in the following scenarios, that is, all terminals have the same priority under fault weakening. If the speaking right in the group call is already group call, reject other group calls.

The "first come, first served" management mechanism in the weakened state of the above faults can only realize simple voice right management, functions such as voice right preemption and high-priority call access cannot be realized, which is important for the trunking system dedicated to command and dispatch The lack of functions and the weakening of faults generally occur in emergency scenarios such as sudden disasters. Without priority control, important calls may not be established and timing may be delayed.

Contents of the invention

In view of this, the main purpose of the present invention is to provide a priority management method in a base station weakened state, which can meet the call requirements of high-priority users in the weakened state.

In order to achieve the above object, the technical scheme proposed by the present invention is:

A priority management method in a base station failure weakened state, comprising:

When the cluster base station is in the normal working mode, for each user equipment (UE), the core network notifies the UE of the priority information of the UE in the group to which it belongs;

When the cluster base station is in the fault weakening mode, the UE reports its own priority information to the cluster base station; the cluster base station performs call management according to the priority information reported by the UE.

To sum up, the priority management method proposed by the present invention under the weakened state of the base station failure, the core network notifies the UE of the priority of the UE in the group to which it belongs when the cluster base station is in the normal mode in advance, and then, in the cluster base station When in the failure weakening mode, the UE sends its priority information to the cluster base station, so that the cluster base station can perform call management based on the priority of the UE, thereby meeting the call needs of high-priority users in the failure weakening state.

Detailed ways

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

The core idea of the present invention is: when the cluster base station is in the normal working mode, the core network notifies the UE of the priority information of the UE; Call management can be performed based on the priority information, so as to meet the call needs of high-priority users in a fault-weakened state.

FIG. 1 is a schematic flow chart of Embodiment 1 of the present invention. As shown in FIG. 1 , the call management method under fault weakening implemented in this embodiment mainly includes the following steps:

Step 101, when the cluster base station is in the normal working mode, for each user equipment UE, the core network notifies the UE of the priority information of the UE in the group to which it belongs.

This step is used to notify the UE of the priority information of the UE in each group to which it belongs, so that the base station can obtain the priority information from the UE when the base station is in the fault weakening mode, so that call management can be performed based on the priority, and then can Meet the call needs of high-priority users in the fault-weakened state.

Preferably, the core network can use the following methods to perform the notification:

The core network pushes the priority information to the UE as the group attribute information of the corresponding group.

Specifically, the timing for performing the notification may include the following scenarios:

When the UE performs initial registration, when the information of the group to which the UE belongs changes, and when the priority information of the UE changes.

Step 102, when the cluster base station is in the fault weakening mode, the UE reports its own priority information to the cluster base station; the cluster base station performs call management according to the priority information reported by the UE .

In this step, when the cluster base station is in the failure weakening mode, the UE needs to report its own priority information to the cluster base station, so that it can perform corresponding call management based on the priority information.

Preferably, the reporting the priority information of itself to the cluster base station includes:

When the UE learns that the cluster base station has entered the fault weakening mode, it initiates a preset reporting process to the cluster base station, and uses the request message in the reporting process to report its priority information in the group to which it belongs to the cluster base station.

What needs to be explained here is that in the existing system, when the cluster base station enters the failure weakening mode, it will instruct the base station to enter the failure weakening mode in the system information broadcast. Therefore, the UE can know that the base station enters the failure weakening mode according to the broadcast information.

Preferably, the reporting process for reporting the above priority information may include: an attach process and/or a registration process. Correspondingly, the request message specifically carrying these priority information may also include: an attach request message and/or a registration request message.

Preferably, performing call management according to the priority information reported by the UE may specifically include the following steps:

Step x1. After the cluster base station receives the priority information reported by the UE, it saves the mapping relationship information between the UE and the group to which it belongs, wherein the mapping relationship information includes the UE in the group to which it belongs. Priority information within the group.

Step x2. When the UE initiates a call, the cluster base station generates the call priority of the call according to the call type, the priority of the calling UE, and the priority of the called UE, and uses the specified call notification A message notifies the calling UE and the called UE of the call priority;

If the UE as the called UE receives two or more call notification messages at the same time, according to the call priority in the call notification information, select the call corresponding to the call notification message with the highest call priority for access.

Preferably, the call notification message may include: a paging message and/or a call setup message.

Step x3: When the UE initiates a speaking right application in a group call, if the applied speaking right is currently occupied, the cluster base station will occupy the UE's priority in the group according to the current speaking right occupation UE and the current speaking right application UE stage, judging whether to grant the speaking right to the speaking right applying UE, and if so, releasing the speaking right of the currently occupied UE and granting the speaking right to the speaking right applying UE.

Preferably, the following method can be used to judge whether to grant the speaking right to the speaking right applying UE:

If the priority in the group of the current speaking right applying UE is higher than the priority in the group of the current speaking right occupying UE, the cluster base station determines to grant the speaking right to the speaking right applying UE.

The judging principle adopted by the above method is: the priority is higher than the existing speaker right occupant, and the speaker is granted the speaker right, so that when the base station is in a fault weakened state, it can respond to the call request of the high-priority user and assign it The right to speak can meet the call needs of high-priority users and ensure the timely establishment of emergency calls in the weakened state.

To sum up, the above are only preferred embodiments of the present invention, and are not intended to limit the protection scope of 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.
