These drawings and descriptions are not intended to limit the scope of the concept in any way, but rather to illustrate the concept of this application to those skilled in the art through reference to particular embodiments. Detailed Implementation

[0053] Exemplary embodiments will now be described in detail, examples of which are illustrated in the accompanying drawings. When the following description relates to the drawings, unless otherwise indicated, the same numbers in different drawings denote the same or similar elements. The embodiments described in the following exemplary embodiments do not represent all embodiments consistent with this application. Rather, they are merely examples of apparatuses and methods consistent with some aspects of this application as detailed in the appended claims.

[0054] Figure 1 This is a schematic diagram of the architecture of the broadband trunking communication system used in the embodiments of this application. Figure 1 As shown, the broadband trunking communication system includes core network equipment 110, wireless access network equipment 120, and at least one terminal device (such as...). Figure 1 The terminal devices 130 and 140 are included in this document. The terminal devices connect wirelessly to the wireless access network equipment, which in turn connects wirelessly or via a wired connection to the core network equipment. The core network equipment and the wireless access network equipment can be independent physical devices, or the functions of the core network equipment and the logical functions of the wireless access network equipment can be integrated onto the same physical device. Alternatively, a single physical device can integrate some of the functions of the core network equipment and some of the functions of the wireless access network equipment. The terminal devices can be fixed in location or mobile. Figure 1 This is just an illustration; the communication system may also include other wireless access network devices, such as wireless repeaters and wireless backhaul devices. Figure 1 Not shown in the diagram. The embodiments of this application do not limit the number of core network devices, radio access network devices, and terminal devices included in the mobile communication system.

[0055] A wireless access network device is an access device that enables terminal devices to access a mobile communication system wirelessly. It can be a base station, an evolved NodeB (eNodeB), a transmission reception point (TRP), a next-generation NodeB (gNB) in a 5G mobile communication system, a base station in a future mobile communication system, or an access node in a WiFi system. It can also be a module or unit that performs some of the functions of a base station; for example, it can be a central unit (CU) or a distributed unit (DU). The embodiments in this application do not limit the specific technology or device form used in the wireless access network device.

[0056] In the embodiments of this application, the apparatus for implementing the functions of a wireless access network device can be a wireless access network device itself; it can also be an apparatus capable of supporting the wireless access network device in implementing the functions, such as a chip system. This apparatus can be installed in or used in conjunction with the wireless access network device. In the technical solutions provided in the embodiments of this application, the example of a wireless access network device as the apparatus for implementing the functions of the wireless access network device is used to describe the technical solutions provided in the embodiments of this application.

[0057] The terminal devices involved in the embodiments of this application can also be referred to as Terminal, User Equipment (UE), Mobile Station (MS), Mobile Terminal (MT), etc. Terminal devices can be mobile phones, tablets, computers with wireless transceiver capabilities, virtual reality terminal devices, augmented reality terminal devices, wireless terminals in industrial control, wireless terminals in autonomous driving, wireless terminals in remote surgery, wireless terminals in smart grids, wireless terminals in transportation safety, wireless terminals in smart cities, wireless terminals in smart homes, and so on. The embodiments of this application do not limit the specific technologies or device forms used in the terminal devices.

[0058] In the aforementioned communication system, the wireless access network equipment needs to communicate not only with the core network equipment but also with the terminal equipment.

[0059] In existing technologies, during broadband trunking communication through the aforementioned broadband trunking communication system, the wireless access network (WLAN) device needs to periodically send messages to the terminal device. For example, if voice and video are involved in the communication, the WLAN device needs to periodically send a Downlink Trunking Information Transfer (DLTrunkingInformationTransfer) message to the terminal device. This message includes talk rights information and video source information. The talk rights information is used to indicate to the terminal device which user the currently playing voice belongs to, and the video source information is used to indicate to the terminal device which user the currently playing video belongs to. Another example is that the WLAN device periodically sends a GroupCallConfig message to the terminal device.

[0060] It can be seen that the wireless access network devices need to send two types of messages periodically, which will result in a large number of messages being sent from the wireless access network devices to the terminal devices, thus reducing the working efficiency of the wireless access network devices.

[0061] To address the aforementioned issues, reducing the number of messages periodically sent by the radio access network (RAN) devices to the terminal devices could improve the operational efficiency of the RAN devices. Therefore, merging downlink trunking information transmission messages and GroupCallConfig messages could be considered.

[0062] In this embodiment of the application, considering that there are many fields in the group call configuration message, while the downlink trunking information transmission message only contains talk rights information and video source information, the talk rights information and video source information are merged into the group call configuration message.

[0063] The following specific embodiments can be combined with each other, and the same or similar concepts or processes may not be described again in some embodiments. The embodiments of this application will be described below with reference to the accompanying drawings.

[0064] Based on the above Figure 1 The broadband trunking communication system shown is Figure 2 This is a flowchart illustrating the steps of a broadband trunking communication method provided in an embodiment of this application. (Refer to...) Figure 2 As shown, the broadband trunking communication method includes S201 to S203.

[0065] S201: The core network device sends a first message to the radio access network device, the first message including at least one of the following: talk rights information, video source information.

[0066] Accordingly, the wireless access network device receives the first message sent by the core network device.

[0067] After receiving the first message, the wireless access network device needs to extract the talk rights information and / or video source information from it.

[0068] S202: In response to the first message, the wireless access network device sends a group call configuration message to the terminal device, the group call configuration message including at least one of the following information: talk rights information, video source information.

[0069] Accordingly, the terminal device receives the group call configuration message sent by the wireless access network device.

[0070] In practical applications, trunked communication typically involves communication between multiple terminal devices. One terminal device, A, initiates a call; A is the calling terminal device. The remaining terminal devices, B, are the called terminal devices. Therefore, in this embodiment, the terminal device can be any terminal device in the group, including both the calling and called terminal devices.

[0071] The existing technology center's group call configuration message includes the following three fields: field F1, which stores group call configuration information groupCallConfigInfo; field F2, which stores dedicated information dedicatedInfoNAS; and field F3, which stores non-critical extension information nonCriticalExtension.

[0072] Each of the above fields can include subfields, and subfields can also include nested subfields. Thus, the group call configuration message is equivalent to a tree structure, with the root node having three child nodes, corresponding to fields F1 to F3 respectively, and each child node can further have child nodes, each corresponding to its subfield.

[0073] Based on the aforementioned tree-structured group call configuration message, the aforementioned wireless access network device can add talk rights information and / or video source information to any location in the group call configuration message.

[0074] In the first strategy, two new fields can be added to the group call configuration message, in a position parallel to fields F1 to F3, to store talk rights information and video source information respectively.

[0075] In the second strategy, since the aforementioned non-critical extended fields are used to store different types of non-critical extended fields, talk rights information and / or video source information can be added to the non-critical extended fields, that is, as sub-fields of the non-critical extended fields.

[0076] Because the non-critical extension fields include various types of non-critical extension subfields. For example, there is the non-critical extension subfield lateNonCriticalExtension used to store information about delays, and the non-critical extension subfield groupMeasGapConfig used to store group measurement gap configurations.

[0077] Therefore, in this embodiment of the application, a target-type non-critical extended subfield can be added to the non-critical extended field to store talk rights information and / or video source information.

[0078] Specifically, before sending the group call configuration message to the terminal device, the radio access network device needs to add the talk rights information and / or video source information to the non-critical extended subfield of the target type, and then add the non-critical extended subfield to the non-critical extended field. In this way, the group call configuration message includes the talk rights information and / or video source information, at which point the radio access network device can send the group call configuration message to the terminal device.

[0079] Furthermore, the non-critical extended subfields of the aforementioned target type may also include unused extended subfields. These extended subfields can be used to further expand the non-critical extended subfields of the target type to increase the amount of information stored and achieve other functions.

[0080] The aforementioned unused extended subfield can be a sequence, which can include extended information of any type, thus improving the flexibility of the unused extended subfield.

[0081] S203: The aforementioned terminal device extracts talk rights information and / or video source information from the group call configuration message.

[0082] It is understandable that the process by which the terminal device extracts talk rights information and / or video source information from the group call configuration message is related to the strategy of the radio access network device in adding talk rights information and / or video source information. That is, if the radio access network device adds talk rights information and / or video source information to the TF field, then the terminal device extracts the talk rights information and / or video source information from the TF field and adds it to the L1 field.

[0083] For the first strategy mentioned above, when the wireless access network device adds talk rights information and / or video source information to the new field in the group call configuration message that is parallel to F1 to F3, the terminal device extracts the talk rights information and / or video source information from the new field.

[0084] For the second strategy mentioned above, when the wireless access network device adds talk rights information and / or video source information to the target type of non-critical extended subfield included in the non-critical extended field, the terminal device first extracts the non-critical extended field from the group call configuration message; then, the terminal device extracts the target type of non-critical extended subfield from the non-critical extended field; finally, the terminal device extracts talk rights information and / or video source information from the non-critical extended subfield.

[0085] Of course, when the aforementioned terminal device extracts the voice rights information and / or video source information, it can display the voice rights information and / or video source information on the terminal device to indicate the user to whom the currently playing voice belongs. In addition, the video source information is used to indicate the user to whom the currently playing video belongs.
