Problems solved by technology

When many users send out requests for speaking rights at the same time, the standard 3GPP recommended speaking right control method may cause the MCPTT server to process multiple signalings at the same time, which will cause the MCPTT server to bear a huge load, which will lead to network congestion and cannot guarantee high reliability of service implementation. elements such as sex and low latency

Embodiment 1

[0042] The embodiment of the present invention proposes a method of speaking right control applicable to multiple MCPTT systems of LTE-R, aiming at proposing a solution for reducing the load of the MCPTT server and preventing network congestion. In this method, the MCPTT server creates user classifications and speaking right groups according to application policies, grants different speaking right request permissions to different types of users, and divides each user into speaking right groups. All users in the same speaking right group belong to same category. Then, the MCPTT server sends the category and the speaking right group to which each user belongs to each user, and the terminal of each user performs the speaking right request operation in the speaking right group to which it belongs according to the corresponding speaking right request permission of the user category to which it belongs.

[0064] Assume that there are three users in the speaking group, namely the first user, the second user, and the third user. The first user is the leader of the speaking right group, and the second user and the third user are group members. The three users respectively initiate a speaking right request by the first speaking right participant, the second speaking right participant, and the third speaking right participant of the user terminal. Participants with the second right to speak and participants with the third right to speak respectively initiate a request for right to speak to the first participant with the right to speak . The first speaking right participant sends a speaking right request to the speaking right control server, and the speaking right control server not...

Suppose there are two MCPTT systems, the first MCPTT system is the master system, and the second MCPTT system is the slave system.

[0069] Both the first speaking right group and the second speaking right group belong to the first MCPTT system, and the speaking right control server in the system is the first speaking right control server. The first speaking right participant user and the second speaking right participant user belong to the first speaking right group, which is a first-class user; the third speaking right participant user belongs to the second speaking right group, and is a second-class user, and is also the second-class user. The group leader of the second speaking right group for...

Abstract

The invention provides a method for controlling user speaking right in an MCPTT (Mission-Critical Push-To-Talk) system. The method comprises the following steps: an MCPTT server creates user categories and speaking right groups according to an application strategy, endows different categories of users with different speaking right request permissions and allocates the users to the speaking right groups, wherein all users in the same speaking right group belong to the same category; and the MCPTT server sends the belonging categories and the speaking right groups of the users to the users, andterminals of the users perform speaking right request operations in the belonging speaking right groups according to the speaking right request permissions corresponding to the belonging user categories. According to the method provided by the invention, the MCPTT server performs arbitration on the speaking right requests of the users based on an optimization strategy, and the MCPTT server only needs to process signaling of the users endowed with the speaking right in advance, thereby effectively reducing the burden of the MCPTT server and avoiding network congestion, and the method can be applicable to scenes in which a plurality of users simultaneously send the speaking right requests in railway business needs.

Description

technical field [0001] The invention relates to the technical field of wireless communication, in particular to a method for controlling a user's speaking right in an MCPTT system. Background technique [0002] With the development of science and technology, the second-generation railway mobile communication system GSM-R cannot carry more communication services such as video due to its low bandwidth and limited carrying capacity. Due to the railway's demand for broadband, LTE-R has become the best choice for the next-generation railway mobile communication system due to its advantages of large bandwidth, high speed, low latency, and the ability to carry more services such as voice, video, and control information. [0003] The International Standardization Organization "Third Generation Partnership Project" 3GPP standard introduces the functional characteristics of mission-critical communication, which has the advantages of high reliability, high availability and low delay. ...
