Description

Method and device for receiving side to actively send message to trigger group information update

technical field

In the digital trunking communication field of the present invention, especially in the CDMA2000 digital trunking system, the receiving side actively sends a notification message to the dispatching server, the device and the method for triggering terminal group information update after the receiving side group management is successful.

Background technique

Trunking communication refers to a dedicated dispatching communication method, including dedicated command and dispatching communication. During use, trunking users can join calls at the same time, and calls work in half-duplex mode. In a broad sense, various wireless communication systems with dispatching communication functions, including wireless intercom systems, can be included in the category of trunking communication systems.

Trunking communication has gone through a simple intercom system (one-to-one intercom form) to a single base station small system (same-frequency simplex networking form, different-frequency single (dual) work networking form, single-channel one call form, with selective call form , multi-channel automatic dialing form), and then to the development process of large-capacity multi-area system (multi-channel user sharing form), and then experienced a leap from analog trunking to digital trunking. More reliable digital processing methods can be used in multiple access methods, speech coding, modulation and demodulation technology, synchronization technology, error detection and error correction, and diversity technology. Two kinds of digital trunking systems widely used at present are iDEN (integratedDigitalEnhancedNetwork) and TETRA (TerrestrialTrunkedRadio) based on TDMA multiple access technology. In order to promote the large-scale application of digital trunking systems and further improve the utilization of frequency resources, a new application trend has emerged in the application of trunking communication systems, which is to combine multiple digital trunking systems for unified use and management, so as to achieve shared Channels and channels, sharing coverage areas, communication services, and sharing costs, will eventually develop cluster applications from individual professional users to multiple group users to achieve shared network operations.

The acceptance side refers to the system that accepts digital trunking system groups, users, groups, and group members to open accounts, cancel accounts, change accounts, and manage rights. The reception side can be a system that operates independently of the digital trunking system, such as a tent; it can also be a reception desk or a database input and output interface (hereinafter referred to as DBIO) of the digital trunking system. The reception side of the present invention includes but not limited to tents, reception desks and DBIOs.

The digital trunking system has three ways of terminal, dispatcher client and reception side for group management. In order to simplify subsequent paging, group management in various ways needs to synchronize the final group information to the terminal. Chinese patent CN200710176180.9 proposes an optimization method for group information update during terminal wireless group management; Chinese patent CN200710138556.7 proposes a method for triggering terminal group information update by network-side scheduling client for group management; and accepted The change of group information caused by side group management cannot be notified to the dispatching server in real time at present, and there is no way for the acceptance side to actively send a notification message to the dispatching server to inform the dispatching server that the group information has changed, resulting in the terminal not being able to update in time group information.

FIG. 2 is a flow chart of the group management trigger terminal at the accepting side to update group information in real time in this embodiment.

Referring to FIG. 2 , the method for triggering terminal real-time group information update by the acceptance side group management includes the following steps:

In step S1, the receiving side initiates a group management request to the scheduling home register (PHR), and if the request is successful, proceed to step S2; otherwise, end the process.

In step S2, the accepting side performs group management operations on the group.

Step S3, if the above-mentioned management operation type is modifying or deleting a group or adding, modifying or deleting group member information, then send a notification message to the scheduling server; otherwise, end the process.

In step S4, the scheduling server sends a group information change acceptance response to the accepting side. If the response is rejected, the process ends, otherwise, enter step S5.

In step S5, the scheduling server starts the terminal group information updating process.

Wherein, the acceptance side includes at least one of a tent, an acceptance desk, and a DBIO; the group management operation includes operations such as query, add, modify, delete group or query, add, modify, delete group members, etc. .

After step S2, a step is further included: if the group management operation fails, the process ends; otherwise, enter step S3.

In step S3, also include the steps of:

If the receiving side is to modify or delete a group operation, then add the operated group information and operation type in the notification message; if the operation is to add, modify or delete group members, then in the said notification message In addition to adding the operated group information, the notification message also adds the operated group member information.

In step S5, the dispatching server (PDS) triggers a subsequent terminal group information update process, and updates the modified group information to the terminal in a timely manner. Please refer to FIG. 3 for the sequence of each step of the method.

Since the group information update technology is a prior art, the present invention will not be described in detail here.

How the acceptance side actively sends a notification message to the dispatching station server is an important part of the method for the acceptance side group management to trigger real-time group information update, and is also the key of the present invention. The following describes in detail how the acceptance side actively sends the notification message to the dispatching server method and device for implementing the method.

Fig. 4 is the flow chart of the method for accepting the lateral dispatching server (PDS) to actively send the notification message in the present embodiment, and it comprises the following steps:

Step S10, judging the result of the group management operation performed by the accepting side on the group;

Step S20, if the management operation is successful, identify the operation type of the group management operation;

In step S30, different notification messages are sent to the scheduling server (PDS) according to the identified group management operation type.

In step S10, the accepting side judges whether the group information in the dispatching attribution register has been successfully managed by the group; if yes, execute step S20, otherwise, end the process.

In step S20, identify the operation type of the group management operation, the operation type includes querying, adding, modifying, deleting group information or querying, adding, modifying, deleting group member information;

In step S30, after identifying the group management operation, the accepting side actively sends a notification message to the scheduling server (PDS) according to the type of the group management operation.

The method also includes the following steps before step S30:

When the group management operation is adding a group, querying a group or group member information, the process ends; otherwise, the next step is to send a notification message to the scheduling server (PDS).

In the above process, since there are no group members when adding a group, and the query of a group or group members does not involve changes in group or group member information, these two operations do not need to update group information. Other management operations, such as: modifying and deleting groups and adding, modifying and deleting group members, after successful operations, the receiving side needs to actively send a group information change notification message to the scheduling server to notify the group or group member information of changes , to trigger the update of the group information of the terminal.

In this embodiment, the structure of the device that realizes that the receiving side 1 actively sends a notification message to the scheduling server is shown in Figure 5, which belongs to a part of the receiving side 1 (the receiving side 1 also includes a group management module 11, etc.), including A group management judging module 12 , a group management identifying module 13 and a message sending module 14 .

The group management judging module 12 is used for judging whether the group management module of the accepting side 1 successfully manages the group and group member information in the scheduling attribution register.

The group management identifying module 13 is used to identify the operation type of the group management, and the operation type includes querying, adding, modifying, deleting a group or querying, adding, modifying, deleting group member information.

The message sending module 14 is used to actively send a notification message to the scheduling server after the group management operation is successful, and it further includes a message classification unit 141:

When the group management operation type identified by the group management identification module 13 is a modification or deletion group operation, the message classification unit 141 adds group information and operation type information to the notification message;

When the type of group management operation identified by the group management identification module 13 is the operation of adding, modifying or deleting group members, the message classification unit 141 simultaneously adds group and group Group member information and operation type information.

The invention proposes a mechanism for accepting active notification from a lateral scheduling server after successful group management in a digital trunking system. After the success of the group management on the accepting side causes the group or group member information to change, the accepting side sends a group information change notification message to the scheduling server to trigger a method for synchronously updating the group or group member information on the affected terminals in real time. This improved method solves the problem that the group information cannot be updated in real time when the receiving side manages the group, standardizes the group management process, and improves the confidentiality of the group call and the effectiveness of the operation.

The above is only a preferred embodiment of the present invention, and does not limit the scope of its patents. Any equivalent structure or equivalent process transformation made by using the description of the present invention and the contents of the accompanying drawings is directly or indirectly used in other related technical fields. All are included in the scope of patent protection of the present invention in the same way.
