[0039] It should be understood that the specific embodiments described herein are only used to explain the present application, and are not used to limit the present application.

[0040] The present application provides a kind of sending method of rail transit broadband cluster service air interface resource configuration, as shown in the figure.Figure 1 , Figure 1 This is a flowchart illustrating the first embodiment of a method for transmitting air interface resource configuration for broadband trunking services in rail transit according to the present invention.

[0041] In this embodiment, the method for sending the air interface resource configuration of the rail transit broadband trunking service includes the following steps:

[0042] Step S10: Obtain the current number of cluster services and preset threshold values ​​within the cell;

[0043] It should be noted that the implementing entity in this embodiment can be a radio transceiver station, i.e., a base station, that transmits information between a mobile communication switching center and a mobile phone terminal within a certain radio coverage area. The following uses a base station as an example to illustrate this embodiment and the subsequent embodiments.

[0044] Understandably, a cluster is a group of independent computers interconnected by a high-speed network, forming a group and managed as a single system. When a client interacts with a cluster, the cluster acts like a single server. A cluster server, on the other hand, brings together many servers to provide the same service.

[0045] It should be understood that the aforementioned preset threshold value can be set in advance through the gateway or through other means. The preset threshold value can be changed according to actual needs. For example, the preset threshold value can be 16, 20, 25, etc. This embodiment and the following embodiments do not limit this.

[0046] It should be noted that trunking services refer to dedicated command and dispatch services provided to multiple departments, units, and other group users by using a trunking network composed of trunking systems with technical features such as channel sharing and dynamic allocation.

[0047] To effectively obtain the current number of cluster services and preset threshold values ​​within the cell, step S10 includes the following steps:

[0048] Step S01: Obtain the preset threshold for sending dedicated air interface messages for trunking services through the broadcast control channel;

[0049] Understandably, the Broadcast Control Channel (BCCH) is a one-to-many unidirectional control channel used by base stations to broadcast common information to mobile stations, transmitting common system control information, such as the Common Control Channel (CCCH) number and whether it is combined with the Independent Dedicated Control Channel (SDCCH).

[0050] It should be noted that the dedicated air interface message for trunking services sent by the broadcast control channel can be a SystemInformationBlockTypeTrunking message.

[0051] Step S02: After establishing or releasing a cluster service, obtain the current number of cluster services in the cell.

[0052] In the specific implementation, after the base station is powered on, it obtains the threshold configuration for sending dedicated air interface messages for trunking services through the broadcast control channel (BCCH), i.e., the preset threshold value. When the base station establishes or releases trunking services, the base station obtains the current number of trunking services in the aforementioned cell.

[0053] Step S20: Compare the current number of cluster services with the preset threshold value;

[0054] In the specific implementation, the number of current trunking services in the cell obtained above is compared with the preset threshold value for sending trunking service dedicated air interface messages through the broadcast control channel (BCCH) to determine the relationship between the two values.

[0055] Step S30: Determine the target control channel based on the comparison result, and send the dedicated air interface message for the trunking service through the target control channel. The dedicated air interface message for the trunking service carries the dedicated air interface resource configuration.

[0056] It should be noted that the comparison results include: the number of current cluster services is greater than the preset threshold and the number of current cluster services is less than or equal to the preset threshold.

[0057] It should be explained that the target control channels include the Broadcast Control Channel (BCCH) and the Cluster Control Channel (TCCH).

[0058] It should be noted that the dedicated air interface messages for cluster services include: the SystemInformationBlockTypeTrunking message of the broadcast control channel and the GroupCallConfig message of the cluster control channel.

[0059] In a specific implementation, when the number of current cluster services is greater than the preset threshold, a dedicated air interface message for the cluster services is sent through the cluster control channel (TCCH), and the dedicated air interface message carries the dedicated air interface resource configuration; when the number of current cluster services is less than or equal to the preset threshold, the dedicated air interface message for the cluster services is sent through the broadcast control channel (BCCH), and the dedicated air interface message carries the dedicated air interface resource configuration.

[0060] For example, refer to Figure 5 ,Figure 5 This diagram illustrates the downlink logical channel mapping relationship for the broadband trunking service air interface resource allocation transmission method of the present invention. The downlink logical channels include BCCH (Broadcast Control Channel), CCCH (Common Control Channel), DCCH (Dedicated Control Channel), DTCH (Dedicated Service Channel), TTCH (Trunking Service Channel), TCCH (Trunking Control Channel), TPCCH (Trunking Paging Control Channel), and PCCH (Paging Control Channel). The downlink transmission channels include BCH (Broadcast Channel), DL-SCH (Downlink Shared Channel), TPCH (High TPS Public Chain Based on Blockchain POW Consensus Mechanism), and PCH (Paging Channel). The downlink physical channels include PBCH (Physical Broadcast Channel), PDSCH (LTE Physical Downlink Channel), PHICH (Physical HARQ Indication Channel), PCFICH (Physical Control Format Indication Channel), and PDCCH (Downlink Physical Control Channel). In the diagram illustrating the downlink logical channel mapping relationship, the trunking control channel is mapped to the downlink shared channel, and the broadcast control channel is mapped to the broadcast channel.

[0061] This embodiment obtains a preset threshold for sending dedicated air interface messages for trunking services via the broadcast control channel; after establishing or releasing a trunking service, it obtains the current number of trunking services in the cell; then compares the current number of trunking services with the preset threshold; finally, it determines the target control channel based on the comparison result and sends the dedicated air interface messages for trunking services through the target control channel, the dedicated air interface messages for trunking services carrying dedicated air interface resource configurations. Because this invention compares the obtained current number of trunking services in the cell with the obtained preset threshold, determines the target control channel based on the comparison result, and sends dedicated air interface messages for trunking services carrying dedicated air interface resource configurations through the target control channel, compared to existing technologies, this invention optimizes the transmission mechanism of dedicated air interface resource configurations for trunking services in the B-TrunC standard, reduces the occupation of control channel resources, increases the cell trunking service capacity, and thus improves system performance.

[0062] refer to Figure 2 , Figure 2 This is a flowchart illustrating the second embodiment of the method for transmitting air interface resources for broadband trunking services in rail transit according to the present invention.

[0063] Based on the first embodiment described above, in this embodiment, step S30 includes:

[0064] Step S301: When the number of current cluster services is less than or equal to the preset threshold, the broadcast control channel is determined as the target control channel;

[0065] Understandably, the Broadcast Control Channel (BCCH) is a one-to-many unidirectional control channel used by base stations to broadcast common information to mobile stations, transmitting common system control information, such as the Common Control Channel (CCCH) number and whether it is combined with the Independent Dedicated Control Channel (SDCCH).

[0066] It should be noted that the number of the aforementioned trunking services refers to the number used in the aforementioned cells.

[0067] Step S302: Send the dedicated air interface message for the trunking service through the broadcast control channel.

[0068] It should be noted that, in order to effectively send the configuration of the dedicated air interface resources for trunking services to the trunking terminal via the broadcast control channel, step S302 specifically includes:

[0069] Step S3021: Send the configuration of the dedicated air interface resources for cluster services to the cluster terminal through the broadcast control channel using the extended SystemInformationBlockTypeTrunking message;

[0070] It should be explained that the extended SystemInformationBlockTypeTrunking message is a SystemInformationBlockTypeTrunking message with added information elements, which carry the dedicated air interface resource configuration for cluster services.

[0071] It should be noted that, in order to effectively implement the optimized transmission mechanism for the dedicated air interface resource configuration of cluster services in the B-TrunC standard, step S30 further includes:

[0072] Step S301': When the number of current cluster services is greater than the preset threshold, the cluster control channel is determined as the target control channel;

[0073] It should be noted that the trunking control channel is a single-point to multi-point downlink logical channel dedicated to the trunking. In the mapping between downlink logical channels and downlink transport channels, the trunking control channel is mapped to the downlink shared channel.

[0074] Step S302': Send the dedicated air interface message for cluster services through the cluster control channel.

[0075] In a specific implementation, when the current number of cluster services is less than or equal to the preset threshold, the broadcast control channel is determined as the target control channel, and the dedicated air interface resource configuration for cluster services is sent to the cluster terminal through the broadcast control channel using the extended SystemInformationBlockTypeTrunking message; when the current number of cluster services is greater than the preset threshold, the cluster control channel is determined as the target control channel, and the dedicated air interface resource configuration for cluster services is sent to the cluster terminal through the GroupCallConfig message of the cluster control channel.

[0076] For example, refer to Figure 4 , Figure 4 This is a schematic diagram of the base station processing flow for the transmission method of air interface resource configuration for broadband trunking services in rail transit according to the present invention. After the base station is powered on, it obtains the threshold configuration for transmitting dedicated air interface messages for trunking services through the broadcast control channel and obtains a preset threshold value. When a trunking service is established or released in a cell, the number of trunking services in the current cell is obtained. When the number of trunking services in the cell is less than the preset threshold, the dedicated air interface resource configuration for trunking services is transmitted to the trunking terminal through the SystemInformationBlockTypeTrunking message of the broadcast control channel (BCCH). When the number of trunking services in the cell is greater than the preset threshold, the dedicated air interface resource configuration for trunking services is transmitted to the trunking terminal through the GroupCallConfig message of the TCCH channel.

[0077] This embodiment obtains a preset threshold for sending dedicated air interface messages for trunking services via the broadcast control channel; after establishing or releasing a trunking service, it obtains the current number of trunking services in the cell; then compares the current number of trunking services with the preset threshold; when a trunking service is established or released in the cell, it obtains the current number of trunking services in the cell; when the number of trunking services in the cell is less than the preset threshold, it sends the dedicated air interface resource configuration for trunking services to the trunking terminal via the SystemInformationBlockTypeTrunking message of the broadcast control channel (BCCH); when the number of trunking services in the cell is greater than the preset threshold, it sends the dedicated air interface resource configuration for trunking services to the trunking terminal via the GroupCallConfig message of the TCCH channel. Because this invention compares the obtained current number of trunking services in the cell with the obtained preset threshold, determines the target control channel based on the comparison result, and sends the dedicated air interface message for trunking services carrying the dedicated air interface resource configuration through the target control channel, compared to the prior art, this invention optimizes the transmission mechanism of dedicated air interface resource configuration for trunking services in the B-TrunC standard, reduces the occupation of control channel resources, increases the cell trunking service capacity, and thus improves system performance.

[0078] refer to Figure 3 , Figure 3 This is a flowchart illustrating the third embodiment of the method for transmitting air interface resources for broadband trunking services in rail transit according to the present invention.

[0079] Based on the second embodiment described above, in this embodiment, before step S3021, the method further includes:

[0080] Step S3011: Obtain the configuration index of the dedicated air interface resources for cluster services according to the type of cluster terminal;

[0081] It should be noted that the trunking terminal can be a wireless communication device with data processing and information communication functions, such as a mobile phone, tablet computer, or vehicle-mounted communication terminal, or an electronic device capable of performing the same or similar functions. Different types of trunking terminals correspond to different configuration indices for the dedicated air interface resources used in trunking services.

[0082] Step S3012: Find the configuration template of the corresponding cluster service dedicated air interface resource according to the configuration index;

[0083] It should be noted that the configuration template is a predefined configuration template for the base station and the cluster terminal.

[0084] Step S3013: Generate dedicated air interface resource configuration for cluster services based on the configuration template;

[0085] Step S3014: Add the cluster service dedicated air interface resource configuration to the SystemInformationBlockTypeTrunking message in the broadcast control channel.

[0086] It should be noted that the dedicated air interface resource configuration for the trunking service is carried in the information cell within the SystemInformationBlockTypeTrunk message of the broadcast control channel.

[0087] In the specific implementation, the configuration index of the dedicated air interface resource configuration for the cluster service is obtained according to the type of the cluster terminal; the configuration template of the corresponding dedicated air interface resource for the cluster service is found according to the configuration index; the dedicated air interface resource configuration for the cluster service is generated according to the configuration template; and an information element is added to the SystemInformationBlockTypeTrunking message of the broadcast control channel, the information element carrying the dedicated air interface resource configuration for the cluster service.

[0088] This embodiment obtains a preset threshold for sending dedicated air interface messages for trunking services via the broadcast control channel; after establishing or releasing a trunking service, it obtains the current number of trunking services in the cell; then compares the current number of trunking services with the preset threshold; when a trunking service is established or released in the cell, it obtains the current number of trunking services in the cell; when the number of trunking services in the cell is less than the preset threshold, it first obtains the configuration index of the dedicated air interface resource configuration for trunking services according to the type of trunking terminal; then it finds the configuration template of the corresponding dedicated air interface resource for trunking services according to the configuration index; then it generates the dedicated air interface resource configuration for trunking services according to the configuration template; it adds the dedicated air interface resource configuration for trunking services to the SystemInformationBlockTypeTrunking message of the broadcast control channel; then it sends the dedicated air interface resource configuration for trunking services to the trunking terminal through the SystemInformationBlockTypeTrunking message of the broadcast control channel (BCCH); when the number of trunking services in the cell is greater than the preset threshold, it sends the dedicated air interface resource configuration for trunking services to the trunking terminal through the GroupCallConfig message of the trunking control channel (TCCH). This invention compares the current number of trunking services within a cell with a preset threshold value, determines the target control channel based on the comparison result, and then transmits a trunking service dedicated air interface message carrying dedicated air interface resource configuration through the target control channel. Compared to existing technologies, this invention optimizes the transmission mechanism of trunking service dedicated air interface resource configuration in the B-TrunC standard, reduces the occupation of control channel resources, increases cell trunking service capacity, and thus improves system performance.
