Embodiment 1
[0145] In this embodiment, the process of initiating the preemption of the speaking right and modifying the parameters by the terminal in the group call is described.
[0146] figure 2 It is a schematic flow diagram of a group of calling terminals initiating the preemption of the right to speak and modifying parameters in an embodiment, wherein UE1 is the terminal that initiates the preemption of the right, UE2 is the original calling terminal, and UE2 becomes the called terminal in the group call after the right to speak is released a member. figure 2 The flow shown is explained as follows:
[0147] Step 1: UE1 initiates a speaking right request, and sends a "FLOOR REQUEST" message to the cluster core network, carrying new call parameters.
[0148] Step 2: If the network agrees to the right preemption, further parameter negotiation: If all terminals in the group support the new parameters suggested by the preempting terminal, the network uses the new parameters as the res...
Embodiment 2
[0165] Most of the procedures in this embodiment are the same as those in Embodiment 1, the difference being that the NAS message group call establishment instruction message in Step 4b and Step 5b of Embodiment 1 is replaced with the right to speak notification message, and the call is added to the right to speak notification message related parameters.
[0166] Both Embodiments 1 and 2 can be used for the rights grab in the group call, and only Embodiment 2 can be used for the rights grab in the half-duplex point call process.
[0167] The specific FLOOR INFORM message design is shown in Table 1:

[0170] The audio description information (Audio Description) and video description information (VideoDescription) in Table 1 are newly added content in this embodiment.
Embodiment 3
[0172] In this embodiment, the process of initiating the preemption of the speaking right and modifying parameters by the terminal in a half-duplex single call is described.
[0173] image 3 It is a schematic flow diagram of the process of preempting the right to speak and modifying parameters initiated by a terminal in a half-duplex single call in Embodiment 3, wherein UE1 is the terminal that initiates the right preemption, and UE2 is the original speaker terminal. image 3 The flow shown is explained as follows:
[0174] Step 1: UE1 initiates a speaking right request, and sends a "FLOOR REQUEST" message to the cluster core network, carrying new call parameters.
[0175] Step 2: If the network agrees to the right preemption, further parameter negotiation: If all terminals support the new parameters suggested by the preemption terminal, the network uses this parameter as the result of parameter negotiation; otherwise, the network selects the parameters, and the preemption i...

Abstract
The application discloses a call parameter reconfiguration method, which is applied to a group call process of cluster communication. The method comprises the following steps: n sending a speaking right preemption request message to a cluster core network by equipment initiating speaking right preemption, and carrying suggested new parameters; if the cluster core network agrees with speaking rightpreemption, performing parameter negotiation, and initiating a speaking right release process to original calling equipment; establishing a special bearer for a right scrambling device according to the new parameters by the cluster core network, initiating a speaking right granting message to the right scrambling device, and sending the new parameters to the right scrambling device; carrying outnecessary modification on a group bearer of called devices by the cluster core network according to the new parameters and sending the new parameters to all the called devices; and processing the datapacket by all the devices participating in the group call according to the new parameters. The invention further provides a call parameter reconfiguration method applied to the half-duplex single call process of cluster communication. By applying the technical scheme disclosed by the appliction, the reconfiguration of the call parameters can be realized in the right grabbing process.
Description
technical field [0001] The present application relates to the technical field of communication, and in particular to a method for reconfiguring call parameters. Background technique [0002] The current B-TrunC protocol specifies a process in which the called terminal initiates the preemption of the speaking right during a group call or a half-duplex single call. The specific process is as figure 1 As shown, the description is as follows: [0003] see figure 1 , assuming that during the current group call process, UE2 has the right to speak, and UE1 initiates the preemption of the right to speak. The process of preempting the right to speak includes the following steps: [0004] Step 1: UE1 initiates a speaking right request, and sends a "FLOOR REQUEST (speaking right preemption request)" message to the cluster core network, and the message carries: CALL ID, media description information, etc. [0005] Step 2: The cluster core network initiates a speaking right release p...
