Detailed Description
In order to make the objects, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are some, but not all, embodiments of the present invention. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
The terms "first," "second," "third," "fourth," and the like in the description and in the claims, as well as in the drawings, if any, are used for distinguishing between similar elements and not necessarily for describing a particular sequential or chronological order. It is to be understood that the data so used is interchangeable under appropriate circumstances such that the embodiments of the invention described herein are, for example, capable of operation in sequences other than those illustrated or otherwise described herein. Furthermore, the terms "comprises," "comprising," and "having," and any variations thereof, are intended to cover a non-exclusive inclusion, such that a process, method, system, article, or apparatus that comprises a list of steps or elements is not necessarily limited to those steps or elements expressly listed, but may include other steps or elements not expressly listed or inherent to such process, method, article, or apparatus.
The most typical service in a trunking system is a group call service, i.e. a user may initiate a call to a specific group at a certain time, the call being in a half duplex mode. In a broadband multimedia system, a cluster can provide voice group calling for users and can also provide services such as video group calling and the like. The group calling features that only one person is allowed to talk at any time, the speaking party obtains the uplink resource, other users are in answering state, the system allocates a downlink shared channel to each cell involved in the group, and the users in the group in the cell all monitor the shared channel in real time. Therefore, only one uplink and one shared downlink are provided at any moment in the cluster group calling process, and the frequency spectrum resources are utilized more efficiently than those of the public network. The half-duplex group call has another characteristic that the speaking right allows the operations of applying, releasing, preempting, queuing and the like, and the management process of the speaking right is closely related to the priority of the user. In addition, the group call setup delay is one of the key indicators of the trunking call, and any trunking system needs to satisfy the system characteristics of fast access.
In the 3rd Generation Partnership Project (3 GPP) protocol document 22.179, Key Performance Indicators (KPIs) for MCPTT group calls are defined as follows:
the MCPTT access time is defined as the time between an MCPTT user requesting to speak and the user obtaining a signal to start speaking. Alternatively, the end-to-end MCPTT access time is defined as the time from when an MCPTT user requests to speak to when the first receiving user confirms the MCPTT call setup. Wherein, the shorter the MCPTT access time or the end-to-end MCPTT access time is, the higher the KIP of the MCPTT calling is. In order to save the initiating time of the MCPTT group calling and further promote the KPI of the MCPTT group calling, the application provides a method, a device, equipment and a storage medium for initiating the MCPTT group calling.
