[0002] Dual-mode base stations refer to base station equipment that can support two different communication modes or standards at the same time. They are common in the field of mobile communications, such as 2G and 3G, 3G and 4G, 4G and 5G. Taking 4G and 5G dual-mode base stations as an example, they can process both 4G and 5G network signals.

Second, they can intelligently switch communication modes according to user terminals and network conditions to ensure a good user experience and provide users with more flexible and efficient network services.
[0003] The dual-mode base station adopts a conventional switching method. The basic process is that for terminals within the coverage area of the dual-mode base station, if they switch from the local dual-mode base station (5G cell) to the local dual-mode base station (4G cell) or from the local dual-mode base station (4G cell) to the local dual-mode base station (5G cell), they must first interact with the core network to complete the switching preparation and switching execution process; however, in some high-traffic dual-mode base station scenarios, such as the edge coverage area of the dual-mode base station with relatively large traffic volume, or frequent 4 / 5G interoperability test scenarios, the base station and core network signaling interactions in the existing switching process are frequent and redundant, resulting in insufficient switching flexibility and low switching efficiency.

DETAILED DESCRIPTION
[0018] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.
[0019] For example, see Figure 1 , Figure 1 It is a flow chart of a terminal communication signal switching method in a high-traffic dual-mode base station scenario in an embodiment of the present invention.
[0020] like Figure 1 As shown, a terminal communication signal switching method for a high-traffic dual-mode base station scenario, the method comprising: S101: A first signal cell in a dual-mode base station receives a measurement report uploaded by at least one communication terminal, and triggers switching of at least one communication terminal to a second signal cell in the dual-mode base station based on the measurement report; During the specific implementation of the present invention, there are a first signal cell and a second signal cell in the dual-mode base station; the first signal cell is a 5G signal cell, and the second signal cell is a 4G signal cell, or the first signal cell is a 4G signal cell, and the second signal cell is a 5G signal cell.
[0021] The first signal cell in the dual-mode base station receives a measurement report uploaded by at least one communication terminal, and triggers switching of at least one communication terminal to the second signal cell in the dual-mode base station based on the measurement report, including: the first signal cell sends a measurement configuration to at least one communication terminal, and the measurement configuration carries the signal measurement frequency and test event corresponding to the second signal cell; the at least one communication terminal detects the signal of the current signal cell based on the measurement configuration, generates a measurement report when the signal of the current signal cell meets the measurement configuration, and uploads the measurement report to the first signal cell; after receiving the measurement report, the first signal cell determines whether the physical cell identifier and frequency of the current signal cell in the measurement report are consistent with the second signal cell in the dual-mode base station; if they are consistent with the second signal cell, the first signal cell triggers switching of at least one communication terminal to the second signal cell in the dual-mode base station based on the measurement report; if they are inconsistent with the second signal cell, enters the regular switching preparation process for regular switching processing.
[0022] Specifically, it is applied to a dual-mode base station, which has two different signal cells, one of which is a 5G signal cell and the other is a 4G signal cell; the signal switching here can be switching from 4G signal to 5G signal, or from 5G signal to 4G signal.
[0023] When at least one communication terminal is connected to one of the signal cells in the dual-mode base, and the signal cell connected to at least one communication terminal is defined as the first signal cell; at this time, the first signal cell will send a measurement configuration to at least one communication terminal connected to it for communication, wherein the measurement configuration carries information such as the measurement frequency of the second signal cell and the test event (for example, B1 / B2); after receiving the measurement configuration, at least one communication terminal executes the conventional measurement reconfiguration requirements according to the measurement configuration, and then generates a measurement report after completing the measurement, wherein the measurement object here is another signal cell that can be detected, and the obtained signal cell can be understood as a signal cell to be switched.
[0024] After generating a measurement report, at least one communication terminal device uploads it to the first signal cell by signaling; and after the first signal cell receives the measurement report, it is necessary to determine whether the physical cell identifier and frequency of the current signal cell in the measurement report are consistent with the second signal cell in the dual-mode base station; the specific judgment method is to use whether the physical cell identifier and frequency in the measurement report are consistent with the second signal cell in the dual-mode base station; if they are consistent, it is determined that the current signal cell is consistent with the second signal cell, otherwise it is determined that the current signal cell is inconsistent with the second signal cell.
[0025] When the current signal cell is consistent with the second signal cell, the first signal cell will trigger the switching of at least one communication terminal to the second signal cell in the dual-mode base station according to the measurement report; otherwise, the conventional switching preparation process is entered to perform conventional switching processing.
[0026] Among them, the conventional switching process is: the first signal cell in the dual-mode base station sends a switching request to the first core network corresponding to the first signal cell; the first core network then sends a switching request to the core network to be switched corresponding to the signal cell to be switched in the conventional base station; the core network to be switched sends a switching request to the signal cell to be switched, and after the signal cell to be switched completes the resource preparation work, it replies to the core network to be switched with a switching request confirmation, and the core network to be switched replies to the first core network with a transfer response; the first core network sends a switching command to the first signal cell, thereby completing the switching preparation work; and in the conventional switching process, each signaling can only have one communication terminal execute the switching task at the same time, and batch switching cannot be realized.
[0027] S102: The first signal cell sends a signal cell switching indication to the second signal cell, and receives a signal cell switching confirmation fed back by the second signal cell based on the signal cell switching indication, wherein the signal cell switching indication and the signal cell switching confirmation respectively carry a communication terminal identifier of at least one communication terminal; In the specific implementation process of the present invention, the first signal cell sends a signal cell switching indication to the second signal cell, and receives a signal cell switching confirmation fed back by the second signal cell based on the signal cell switching indication, including: the first signal cell generates the signal cell switching indication, and sends the signal cell switching indication to the second signal cell; after the second signal cell receives the signal cell switching indication, the second signal cell prepares wireless communication resources for the at least one communication terminal, generates the signal cell switching confirmation, and feeds back the signal cell switching confirmation to the first signal cell; the first signal cell receives the signal cell switching confirmation fed back by the second signal cell.
[0028] Specifically, the first signal cell will generate a signal cell switching indication and send the signal cell switching indication to the second signal cell; the signal cell switching indication carries the communication terminal identifier of at least one communication terminal. It can be understood that the communication terminal identifier of each communication terminal that needs to perform signal cell switching is carried in the signal cell switching indication; thereby realizing batch execution of the switching process.
[0029] After receiving the signal cell switching indication, the second signal cell prepares wireless communication resources for at least one communication terminal, generates a signal cell switching confirmation, and feeds back the signal cell switching confirmation to the first signal cell; the first signal cell receives the signal cell switching confirmation fed back by the second signal cell.
[0030] The communication terminal identifier can use IMEI (International Mobile Equipment Identity) or IMSI (International Mobile Subscriber Identity); the number of communication terminal identifiers can be set according to demand, for example, a maximum of 5; the detection time of communication terminals of the same switching type can be set according to demand, for example, 200ms; Example: Within 200ms, the dual-mode base station (first signal cell) receives measurement reports from 10 terminals carrying the same-station dual-mode base station (second signal cell), then the transfer indication is sent twice, each carrying 5 terminal identifiers, and the sending interval of the two transfer indications can be set according to demand, for example, 100ms.
[0031] S103: The first signal cell simultaneously sends a signal cell switching command to at least one communication terminal based on the signal cell switching confirmation, and the at least one communication terminal switches to the second signal cell based on the signal cell switching command; In the specific implementation process of the present invention, the first signal cell simultaneously sends a signal cell switching command to at least one communication terminal based on the signal cell switching confirmation, and the at least one communication terminal switches to the second signal cell based on the signal cell switching command, including: the first signal cell generates a signal cell switching command based on the signal cell switching confirmation, and simultaneously sends the signal cell switching command to the at least one communication terminal; after receiving the signal cell switching command, the at least one communication terminal simultaneously initiates a random access request to the second signal cell in the dual-mode base station based on the signal cell switching command, and switches to the second signal cell based on the random access request.
[0032] The first signal cell will generate a signal cell switching command according to the signal cell switching confirmation, wherein the signal cell switching command contains the communication terminal identification of at least one communication terminal; then the signal cell switching command is simultaneously issued to at least one communication terminal; and after at least one communication terminal receives the signal cell switching command, it will simultaneously initiate a random access request to the second signal cell in the dual-mode base station through the signal cell switching command, and switch to the second signal cell according to the random access request; in this way, at least one communication terminal can quickly execute the switching process in batches.
[0033] S104: After at least one communication terminal switches to the second signal cell, the first signal cell executes UE context release of at least one communication terminal, and feeds back UE release completion to the second signal cell; In the specific implementation process of the present invention, the first signal cell executes UE text release of at least one communication terminal and feeds back UE release completion to the second signal cell, including: the second signal cell sends a UE text release notification to the first signal cell, and the UE text release notification carries a communication terminal identifier of at least one communication terminal; after receiving the UE text release notification, the first signal cell executes UE text release of the at least one communication terminal based on the UE text release notification, and the UE text release is whether the wireless resources of at least one communication terminal are used; the first signal cell feeds back UE release completion to the second signal cell.
[0034] Specifically, the second signal cell sends a UE (User Equipment) text release notification to the first signal cell; after receiving the UE text release notification, the first signal cell releases the wireless resources of the communication terminal corresponding to the UE text release notification; and then replies to the second signal cell with a UE text release completion.
[0035] In the conventional switching process, the UE text release process is the last step in the entire switching process. Since the first signal cell and the second signal cell used in the dual-mode base station in this embodiment belong to the same physical base station, signaling interaction can be completed internally. By pre-positioning the release process, the resource release of the first signal cell in the dual-mode base station is accelerated, thereby improving the switching execution efficiency.
[0036] S105: The second core network corresponding to the second signal cell sends a UE release completion and core network switching completion notification to the first core network corresponding to the first signal cell, and the first core network returns a UE release confirmation and a core network switching confirmation to the second core network based on the UE release completion and core network switching completion notification.
[0037] During the specific implementation of the present invention, the second core network corresponding to the second signal cell sends a UE release completion and a core network switching completion notification to the first core network corresponding to the first signal cell, including: after the at least one communication terminal switches to the second signal cell and the wireless resources of the at least one communication terminal on the first signal cell side are released, the second signal cell sends a UE release completion and a core network switching notification to the second core network; the second core network performs a core network switching operation based on the core network switching notification, and obtains a core network switching completion notification when the second core network completes the core network switching operation; the second core network sends the UE release completion and the core network switching completion notification to the first core network corresponding to the first signal cell.
[0038] Further, the first core network returns UE release confirmation and core network switching completion confirmation to the second core network based on the UE release completion and core network switching completion notification, including: after receiving the UE release completion and the core network switching completion notification, the first core network performs a confirmation operation based on the UE release completion and the core network switching completion notification, and returns UE release confirmation and core network switching completion confirmation to the second core network.
[0039] Specifically, after at least one communication terminal switches to the second signal cell in the dual-mode base station and the wireless resources of at least one communication terminal on the first signal cell side are released, the second signal cell will send a UE release completion and core network switching notification to the second core network corresponding to the second signal cell; it is used to inform the second core network that these communication terminals have released the resources on the first signal cell side of the dual-mode base station and have switched normally to the second signal cell side of the dual-mode base station.
[0040] The second core network will then perform the core network switching operation according to the core network switching notification, and obtain the core network switching completion notification when the second core network completes the core network switching operation; the second core network sends the UE release completion and core network switching completion notification to the first core network corresponding to the first signal cell; it is used to notify the first core network that these communication terminals have released the resources of the first signal cell and have switched to the second signal cell.
[0041] After receiving the release completion and core network switching completion notifications, the first core network will perform confirmation operations through the UE release completion and core network switching completion notifications, and after completing the confirmation operations, return the UE release confirmation and core network switching completion confirmation to the second core network; used to inform the second core network that it is aware of the release of resources of these communication terminals and the switching transfer.
[0042] In the embodiment of the present invention, the signaling interaction process between the two core networks in the dual-mode base station is simplified, and the switching process of batch processing of multiple communication terminals is realized, thereby improving the switching efficiency, optimizing and pre-setting the UE text release process, and speeding up the switching process.
[0043] For example 2, please refer to Figure 2 , Figure 2 It is a flowchart of a terminal communication signal switching method in a high-traffic dual-mode base station scenario in another embodiment of the present invention.
[0044] like Figure 2 As shown, a terminal communication signal switching method for a high-traffic dual-mode base station scenario is provided, wherein the execution entities included in the method include a communication terminal, a first signal cell in the dual-mode base station, a second signal cell in the dual-mode base station, a first core network, and a second core network.
[0045] The first signal cell sends a measurement reconfiguration to the communication terminal, and the communication terminal generates a measurement report based on the reconfiguration measurement and transmits it back to the first signal cell; the first signal cell determines whether it is necessary to switch to the second signal cell in the same dual-mode base station based on the measurement reconfiguration report; when necessary, a switching indication is sent to the second signal cell, and then a switching confirmation is received from the second signal cell based on the switching indication; then the first signal cell sends a switching command to the communication terminal, and the communication terminal switches to the second signal cell and completes the switching; the second signal cell sends a UE text release notification to the first signal cell, and after the first signal cell completes the release based on the UE text release notification, it notifies the second signal cell; the second signal cell sends a UE release completion and switching notification to the second core network corresponding to the second signal cell; the second core network sends a UE release completion and switching completion notification to the first core network corresponding to the first signal cell, and then the first core network returns the UE release confirmation and switching completion confirmation to the second core network.
[0046] The specific implementation methods can be found in the above embodiments, which will not be described in detail here.
[0047] For example 3, please refer to Figure 3 , Figure 3 It is a schematic diagram of the structural composition of a terminal communication signal switching device for a high-traffic dual-mode base station scenario in an embodiment of the present invention.
[0048] like Figure 3 As shown, a terminal communication signal switching device for a high-traffic dual-mode base station scenario, the device comprising: The switching trigger module 301 is used for a first signal cell in a dual-mode base station to receive a measurement report uploaded by at least one communication terminal, and trigger the switching of at least one communication terminal to a second signal cell in the dual-mode base station based on the measurement report; During the specific implementation of the present invention, there are a first signal cell and a second signal cell in the dual-mode base station; the first signal cell is a 5G signal cell, and the second signal cell is a 4G signal cell, or the first signal cell is a 4G signal cell, and the second signal cell is a 5G signal cell.

[0050] Specifically, it is applied to a dual-mode base station, which has two different signal cells, one of which is a 5G signal cell and the other is a 4G signal cell; the signal switching here can be switching from 4G signal to 5G signal, or from 5G signal to 4G signal.
[0051] When at least one communication terminal is connected to one of the signal cells in the dual-mode base, and the signal cell connected to at least one communication terminal is defined as the first signal cell; at this time, the first signal cell will send a measurement configuration to at least one communication terminal connected to it for communication, wherein the measurement configuration carries information such as the measurement frequency of the second signal cell and the test event (for example, B1 / B2); after receiving the measurement configuration, at least one communication terminal executes the conventional measurement reconfiguration requirements according to the measurement configuration, and then generates a measurement report after completing the measurement, wherein the measurement object here is another signal cell that can be detected, and the obtained signal cell can be understood as a signal cell to be switched.
[0052] After generating a measurement report, at least one communication terminal device uploads it to the first signal cell by signaling; and after the first signal cell receives the measurement report, it is necessary to determine whether the physical cell identifier and frequency of the current signal cell in the measurement report are consistent with the second signal cell in the dual-mode base station; the specific judgment method is to use whether the physical cell identifier and frequency in the measurement report are consistent with the second signal cell in the dual-mode base station; if they are consistent, it is determined that the current signal cell is consistent with the second signal cell, otherwise it is determined that the current signal cell is inconsistent with the second signal cell.
[0053] When the current signal cell is consistent with the second signal cell, the first signal cell will trigger the switching of at least one communication terminal to the second signal cell in the dual-mode base station according to the measurement report; otherwise, the conventional switching preparation process is entered to perform conventional switching processing.
[0054] Among them, the conventional switching process is: the first signal cell in the dual-mode base station sends a switching request to the first core network corresponding to the first signal cell; the first core network then sends a switching request to the core network to be switched corresponding to the signal cell to be switched in the conventional base station; the core network to be switched sends a switching request to the signal cell to be switched, and after the signal cell to be switched completes the resource preparation work, it replies to the core network to be switched with a switching request confirmation, and the core network to be switched replies to the first core network with a transfer response; the first core network sends a switching command to the first signal cell, thereby completing the switching preparation work; and in the conventional switching process, each signaling can only have one communication terminal execute the switching task at the same time, and batch switching cannot be realized.

It can be understood that the communication terminal identifier of each communication terminal that needs to perform signal cell switching is carried in the signal cell switching indication; thereby realizing batch execution of the switching process.
[0057] After receiving the signal cell switching indication, the second signal cell prepares wireless communication resources for at least one communication terminal, generates a signal cell switching confirmation, and feeds back the signal cell switching confirmation to the first signal cell; the first signal cell receives the signal cell switching confirmation fed back by the second signal cell.
[0058] The communication terminal identifier can use IMEI (International Mobile Equipment Identity) or IMSI (International Mobile Subscriber Identity); the number of communication terminal identifiers can be set according to demand, for example, a maximum of 5; the detection time of communication terminals of the same switching type can be set according to demand, for example, 200ms; Example: Within 200ms, the dual-mode base station (first signal cell) receives measurement reports from 10 terminals carrying the same-station dual-mode base station (second signal cell), then the transfer indication is sent twice, each carrying 5 terminal identifiers, and the sending interval of the two transfer indications can be set according to demand, for example, 100ms.
[0059] A switching command issuing module 303: configured for the first signal cell to simultaneously issue a signal cell switching command to at least one communication terminal based on the signal cell switching confirmation, and the at least one communication terminal switches to the second signal cell based on the signal cell switching command; In the specific implementation process of the present invention, the first signal cell simultaneously sends a signal cell switching command to at least one communication terminal based on the signal cell switching confirmation, and the at least one communication terminal switches to the second signal cell based on the signal cell switching command, including: the first signal cell generates a signal cell switching command based on the signal cell switching confirmation, and simultaneously sends the signal cell switching command to the at least one communication terminal; after receiving the signal cell switching command, the at least one communication terminal simultaneously initiates a random access request to the second signal cell in the dual-mode base station based on the signal cell switching command, and switches to the second signal cell based on the random access request.
[0060] The first signal cell will generate a signal cell switching command according to the signal cell switching confirmation, wherein the signal cell switching command contains the communication terminal identification of at least one communication terminal; then the signal cell switching command is simultaneously issued to at least one communication terminal; and after at least one communication terminal receives the signal cell switching command, it will simultaneously initiate a random access request to the second signal cell in the dual-mode base station through the signal cell switching command, and switch to the second signal cell according to the random access request; in this way, at least one communication terminal can quickly execute the switching process in batches.
[0061] Release execution module 304: configured to, after at least one communication terminal switches to the second signal cell, execute, by the first signal cell, UE text release of at least one communication terminal, and feedback UE release completion to the second signal cell; In the specific implementation process of the present invention, the first signal cell executes UE text release of at least one communication terminal and feeds back UE release completion to the second signal cell, including: the second signal cell sends a UE text release notification to the first signal cell, and the UE text release notification carries a communication terminal identifier of at least one communication terminal; after receiving the UE text release notification, the first signal cell executes UE text release of the at least one communication terminal based on the UE text release notification, and the UE text release is whether the wireless resources of at least one communication terminal are used; the first signal cell feeds back UE release completion to the second signal cell.
[0062] Specifically, the second signal cell sends a UE (User Equipment) text release notification to the first signal cell; after receiving the UE text release notification, the first signal cell releases the wireless resources of the communication terminal corresponding to the UE text release notification; and then replies to the second signal cell with a UE text release completion.
[0063] In the conventional switching process, the UE text release process is the last step in the entire switching process. Since the first signal cell and the second signal cell used in the dual-mode base station in this embodiment belong to the same physical base station, signaling interaction can be completed internally. By pre-positioning the release process, the resource release of the first signal cell in the dual-mode base station is accelerated, thereby improving the switching execution efficiency.
[0064] Confirmation module 305: The second core network corresponding to the second signal cell sends a UE release completion and core network switching completion notification to the first core network corresponding to the first signal cell, and the first core network returns a UE release confirmation and a core network switching confirmation to the second core network based on the UE release completion and core network switching completion notification.
[0065] During the specific implementation of the present invention, the second core network corresponding to the second signal cell sends a UE release completion and a core network switching completion notification to the first core network corresponding to the first signal cell, including: after the at least one communication terminal switches to the second signal cell and the wireless resources of the at least one communication terminal on the first signal cell side are released, the second signal cell sends a UE release completion and a core network switching notification to the second core network; the second core network performs a core network switching operation based on the core network switching notification, and obtains a core network switching completion notification when the second core network completes the core network switching operation; the second core network sends the UE release completion and the core network switching completion notification to the first core network corresponding to the first signal cell.
[0066] Further, the first core network returns UE release confirmation and core network switching completion confirmation to the second core network based on the UE release completion and core network switching completion notification, including: after receiving the UE release completion and the core network switching completion notification, the first core network performs a confirmation operation based on the UE release completion and the core network switching completion notification, and returns UE release confirmation and core network switching completion confirmation to the second core network.
[0067] Specifically, after at least one communication terminal switches to the second signal cell in the dual-mode base station and the wireless resources of at least one communication terminal on the first signal cell side are released, the second signal cell will send a UE release completion and core network switching notification to the second core network corresponding to the second signal cell; it is used to inform the second core network that these communication terminals have released the resources on the first signal cell side of the dual-mode base station and have switched normally to the second signal cell side of the dual-mode base station.
[0068] The second core network will then perform the core network switching operation according to the core network switching notification, and obtain the core network switching completion notification when the second core network completes the core network switching operation; the second core network sends the UE release completion and core network switching completion notification to the first core network corresponding to the first signal cell; it is used to notify the first core network that these communication terminals have released the resources of the first signal cell and have switched to the second signal cell.
[0069] After receiving the release completion and core network switching completion notifications, the first core network will perform confirmation operations through the UE release completion and core network switching completion notifications, and after completing the confirmation operations, return the UE release confirmation and core network switching completion confirmation to the second core network; used to inform the second core network that it is aware of the release of resources of these communication terminals and the switching transfer.
[0070] In the embodiment of the present invention, the signaling interaction process between the two core networks in the dual-mode base station is simplified, and the switching process of batch processing of multiple communication terminals is realized, thereby improving the switching efficiency, optimizing and pre-setting the UE text release process, and speeding up the switching process.
