Description

Technical Field

[0001] The present invention relates to the field of communication technologies, and in particular, to a method for switching terminal communication signals in a high-traffic dual-mode base station scenario and related devices. Background Art

[0002] A dual-mode base station refers to a base station device that can support two different communication modes or standards simultaneously. It is common in the field of mobile communication, such as different combinations of 2G and 3G, 3G and 4G, 4G and 5G, etc.; taking a 4G and 5G dual-mode base station as an example, it can process both 4G network signals and 5G network signals; the advantages of a dual-mode base station are, firstly, to avoid duplicate construction and reduce the costs of operators; secondly, it can intelligently switch communication modes according to the user terminal and network conditions, ensuring a good experience for users, and can also provide more flexible and efficient network services for users.

[0003] The dual-mode base station adopts a conventional switching method. The basic process is that for a terminal within the coverage area of the dual-mode base station, if it switches from the dual-mode base station of this station (5G cell) to the dual-mode base station of this station (4G cell) or from the dual-mode base station of this station (4G cell) to the dual-mode base station of this station (5G cell), it must first go through the interaction between core networks to complete the handover preparation and handover execution processes; however, in some high-traffic dual-mode base station scenarios, such as the edge coverage area of a dual-mode base station with a relatively large traffic volume, or a scenario where 4 / 5G interworking tests are frequently carried out, the signaling interaction between the base station and the core network in the existing handover process is frequent and redundant, resulting in insufficient handover flexibility and low handover efficiency. Summary of the Invention

[0049] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0050] Embodiment 1. Please refer to Figure 1 , Figure 1 It is a schematic flow chart of a method for switching terminal communication signals in a high-traffic dual-mode base station scenario in an embodiment of the present invention.

[0051] As Figure 1 shown, a method for switching terminal communication signals in a high-traffic dual-mode base station scenario, the method includes:

[0052] S101: The first signal cell in the dual-mode base station receives measurement reports uploaded by at least one communication terminal, and triggers switching at least one communication terminal to the second signal cell in the dual-mode base station based on the measurement reports;

[0053] In the specific implementation process 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.

[0054] The first signal cell in the dual-mode base station receives measurement reports uploaded by at least one communication terminal, and triggers the handover of at least one communication terminal to the second signal cell in the dual-mode base station based on the measurement reports, including: the first signal cell sends measurement configurations to at least one communication terminal, and the measurement configurations carry signal measurement frequency points and test events corresponding to the second signal cell; the at least one communication terminal detects the signal of the current signal cell based on the measurement configurations, generates a measurement report when the signal of the current signal cell meets the measurement configurations, 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 point of the current signal cell in the measurement report are the same as those of the second signal cell in the dual-mode base station; if they are the same as those of the second signal cell, the first signal cell triggers the handover 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 not the same as those of the second signal cell, it enters the conventional handover preparation process for conventional handover processing.

[0055] Specifically, it is applied to a dual-mode base station, in which there are two different signal cells in the dual-mode base station, one of which is a 5G signal cell and the other is a 4G signal cell; the signal handover here can be from a 4G signal to a 5G signal or from a 5G signal to a 4G signal.

[0056] When at least one communication is connected to one of the signal cells in the dual-mode base station, and the signal cell to which at least one communication terminal is connected is defined as the first signal cell; at this time, the first signal cell will send measurement configurations to at least one communication terminal connected to it, and the measurement configurations carry measurement frequency points of the second signal cell and information such as test events (such as B1 / B2), etc.; after receiving the measurement configurations, at least one communication terminal executes the conventional measurement reconfiguration requirements according to the measurement configurations, and then generates a measurement report after completing the measurement. Here, the measurement object is the other signal cell that can be detected, and the signal cell to be handed over can be obtained.

[0057] After generating the measurement report, at least one communication terminal device uploads it to the first signal cell through signaling; and after the first signal cell receives the measurement report, it is necessary to determine whether the physical cell identifier and frequency point of the current signal cell in the measurement report are the same as those of the second signal cell in the dual-mode base station; the specific determination method is to use whether the physical cell identifier and frequency point in the measurement report are the same as those of the second signal cell in the dual-mode base station; if they are the same, it is determined that the current signal cell is the same as the second signal cell, otherwise it is determined that the current signal cell is not the same as the second signal cell.

[0058] When the current signal cell is the same as the second signal cell, the first signal cell will trigger the handover of at least one communication terminal to the second signal cell in the dual-mode base station according to the measurement report; otherwise, it enters the conventional handover preparation process for conventional handover processing.

[0059] Among them, the conventional handover process is as follows: The first signal cell in the dual-mode base station sends a handover request to the first core network corresponding to the first signal cell; the first core network then sends a handover request to the target core network corresponding to the target signal cell in the conventional base station; the target core network sends a handover request to the target signal cell. After the target signal cell completes the resource preparation work, it sends a handover request confirmation to the target core network, and the target core network sends a handover response to the first core network; the first core network issues a handover command to the first signal cell, thus completing the handover preparation work; and during the conventional handover process, only one communication terminal can execute the handover task for each signaling, and batch handover during operation cannot be achieved.

[0060] S102: The first signal cell sends a signal cell handover indication to the second signal cell and receives a signal cell handover confirmation feedback by the second signal cell based on the signal cell handover indication. The signal cell handover indication and the signal cell handover confirmation respectively carry the communication terminal identifiers of at least one communication terminal;

[0061] In the specific implementation process of the present invention, the first signal cell sends a signal cell handover indication to the second signal cell and receives a signal cell handover confirmation feedback by the second signal cell based on the signal cell handover indication, including: the first signal cell generates the signal cell handover indication and sends the signal cell handover indication to the second signal cell; after receiving the signal cell handover indication, the second signal cell prepares radio communication resources for the at least one communication terminal, generates the signal cell handover confirmation, and feeds back the signal cell handover confirmation to the first signal cell; the first signal cell receives the signal cell handover confirmation fed back by the second signal cell.

[0062] Specifically, the first signal cell will generate a signal cell handover indication and send the signal cell handover indication to the second signal cell; the signal cell handover indication carries the communication terminal identifiers of at least one communication terminal. It can be understood that the communication terminal identifiers of each communication terminal that needs to perform signal cell handover are carried in the signal cell handover indication; thus, the batch execution of the handover process is realized.

[0063] 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.

[0064] 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.

[0065] 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;

[0066] 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.

[0067] 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.

[0068] S104: After at least one communication terminal switches to the second signal cell, the first signal cell performs UE context release for at least one communication terminal and feeds back UE release completion to the second signal cell.

[0069] In the specific implementation process of the present invention, the first signal cell performs UE context release for at least one communication terminal and feeds back UE release completion to the second signal cell, including: the second signal cell sends a UE context release notification to the first signal cell, and the UE context release notification carries the communication terminal identifiers of at least one communication terminal; after receiving the UE context release notification, the first signal cell performs the UE context release for at least one communication terminal based on the UE context release notification, and the UE context release is the radio resources of whether at least one communication terminal; the first signal cell feeds back UE release completion to the second signal cell.

[0070] Specifically, the second signal cell sends a UE (User Equipment) context release notification to the first signal cell; after receiving the UE context release notification, the first signal cell will release the radio resources of the communication terminal corresponding to the UE context release notification; and then reply a UE release completion to the second signal cell.

[0071] In the conventional handover process, the UE context release process is the last step in the entire handover process. Since the first signal cell and the second signal cell in the dual-mode base station in this embodiment belong to the same physical base station, signaling interaction can be completed internally, and by advancing this release process, the resource release of the first signal cell in the dual-mode base station is accelerated, thereby improving the handover execution efficiency.

[0072] S105: The second core network corresponding to the second signal cell sends a UE release completion and a core network handover 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 handover confirmation to the second core network based on the UE release completion and the core network handover completion notification.

[0073] In the specific implementation process of the present invention, the second core network corresponding to the second signal cell sends a UE release completion and core network handover 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 radio 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 core network handover notification to the second core network; the second core network performs a core network handover operation based on the core network handover notification, and obtains a core network handover completion notification when the second core network completes the core network handover operation; the second core network sends the UE release completion and the core network handover completion notification to the first core network corresponding to the first signal cell.

[0074] Further, the first core network returns a UE release confirmation and a core network handover completion confirmation to the second core network based on the UE release completion and core network handover completion notification, including: after receiving the UE release completion and the core network handover completion notification, the first core network performs a confirmation operation based on the UE release completion and the core network handover completion notification, and returns a UE release confirmation and a core network handover completion confirmation to the second core network.

[0075] Specifically, after at least one communication terminal switches to the second signal cell in the dual-mode base station and the radio resources of the 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 handover notification to the second core network corresponding to the second signal cell; to inform the second core network that these communication terminals have been released from the resources on the first signal cell side of the dual-mode base station and have been normally switched to the second signal cell side of the dual-mode base station.

[0076] Then the second core network will perform a core network handover operation according to the core network handover notification, and obtain a core network handover completion notification when the second core network completes the core network handover operation; the second core network sends the UE release completion and core network handover completion notification to the first core network corresponding to the first signal cell; to notify the first core network that these communication terminals have been released from the resources of the first signal cell and have been switched to access the second signal cell.

[0077] After receiving the release completion and core network handover completion notification, the first core network will perform a confirmation operation through the UE release completion and core network handover completion notification, and after completing the confirmation operation, return a UE release confirmation and a core network handover completion confirmation to the second core network; to inform the second core network that it is aware of the release of resources of these communication terminals and the situation of being switched and transferred.

[0078] In the embodiments of the present invention, the signaling interaction process between two core networks in a dual-mode base station is simplified, and the handover process of multiple communication terminals is processed in batches, improving the handover efficiency. Moreover, the UE text release process is optimized and advanced, accelerating the handover process.

[0079] Embodiment 2. Please refer to Figure 2 , Figure 2 which is a schematic flowchart of a method for switching terminal communication signals in a high-traffic dual-mode base station scenario according to another embodiment of the present invention.

[0080] As Figure 2 shown, a method for switching terminal communication signals in a high-traffic dual-mode base station scenario includes execution entities such as 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.

[0081] Among them, the first signal cell sends measurement reconfiguration to the communication terminal, and the communication terminal will generate a measurement report according to the measurement reconfiguration for reconfiguration measurement and send it back to the first signal cell; the first signal cell will judge whether to switch to the second signal cell in the same dual-mode base station according to the measurement report; when necessary, send a handover instruction to the second signal cell, and then receive the handover confirmation returned by the second signal cell according to the handover instruction; then the first signal cell sends a handover command to the communication terminal, and the communication terminal switches to the second signal cell to complete the handover; the second signal cell sends a UE text release notice to the first signal cell, and after the first signal cell completes the release according to the UE text release notice, it notifies the second signal cell; the second signal cell sends a UE release completion and handover notice to the second core network corresponding to the second signal cell; the second core network sends a UE release completion and handover completion notice to the first core network corresponding to the first signal cell, and then the first core network returns a UE release confirmation and handover completion confirmation to the second core network.

[0082] For the specific implementation manner, reference can be made to the above embodiments and will not be elaborated here.

[0083] Embodiment 3. Please refer to Figure 3 , Figure 3 which is a schematic diagram of the structural composition of a terminal communication signal switching device in a high-traffic dual-mode base station scenario according to an embodiment of the present invention.

[0084] As Figure 3 shown, a terminal communication signal switching device in a high-traffic dual-mode base station scenario includes:

[0085] A handover trigger module 301: used for the first signal cell in the dual-mode base station to receive measurement reports uploaded by at least one communication terminal and trigger the handover of at least one communication terminal to the second signal cell in the dual-mode base station based on the measurement reports;

[0086] In the specific implementation process 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.

[0087] When the first signal cell in the dual-mode base station receives measurement reports uploaded by at least one communication terminal and triggers the handover of at least one communication terminal to the second signal cell in the dual-mode base station based on the measurement reports, it includes: the first signal cell sends measurement configurations to at least one communication terminal, and the measurement configurations carry signal measurement frequency points and test events corresponding to the second signal cell; the at least one communication terminal detects the signals of the current signal cell based on the measurement configurations, generates a measurement report when the signals of the current signal cell meet the measurement configurations, 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 point of the current signal cell in the measurement report are the same as those of the second signal cell in the dual-mode base station; if they are the same as those of the second signal cell, the first signal cell triggers the handover 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 not the same as those of the second signal cell, it enters the conventional handover preparation process for conventional handover processing.

[0088] Specifically, applied to a dual-mode base station, where there are two different signal cells in the dual-mode base station, one of which is a 5G signal cell and the other is a 4G signal cell; the signal handover here can be from a 4G signal to a 5G signal or from a 5G signal to a 4G signal.

[0089] When at least one communication is connected to one of the signal cells in the dual-mode base station, and the signal cell to which at least one communication terminal is connected is defined as the first signal cell; at this time, the first signal cell will send measurement configurations to at least one communication terminal connected to it, where the measurement configurations carry measurement frequency points of the second signal cell and information such as test events (such as B1 / B2); after receiving the measurement configurations, at least one communication terminal executes the conventional measurement reconfiguration requirements according to the measurement configurations, and then generates a measurement report after completing the measurement. Here, the measurement object is the other signal cell that can be detected, and the obtained signal cell can be understood as the signal cell to be handed over.

[0090] After at least one communication terminal device generates a measurement report, it uploads the report 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 point of the current signal cell in the measurement report are consistent with those of the second signal cell in the dual-mode base station; specifically, the determination method is to check whether the physical cell identifier and frequency point in the measurement report are consistent with those of 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.

[0091] When the current signal cell is consistent with the second signal cell, the first signal cell will trigger the handover of at least one communication terminal to the second signal cell in the dual-mode base station according to the measurement report; otherwise, it enters the conventional handover preparation process for conventional handover processing.

[0092] Among them, the conventional handover process is as follows: The first signal cell in the dual-mode base station sends a handover request to the first core network corresponding to the first signal cell; the first core network then sends a handover request to the target core network corresponding to the target signal cell in the conventional base station; the target core network sends a handover request to the target signal cell, and after the target signal cell completes the resource preparation work, it sends a handover request confirmation to the target core network, and the target core network sends a transfer response to the first core network; the first core network issues a handover command to the first signal cell, thus completing the handover preparation work; and during the conventional handover process, only one communication terminal can execute the handover task for each signaling, and batch handover operations cannot be achieved.

[0093] Receiving module 302: It is used for the first signal cell to send a signal cell handover indication to the second signal cell and receive the signal cell handover confirmation feedback by the second signal cell based on the signal cell handover indication. The signal cell handover indication and the signal cell handover confirmation respectively carry the communication terminal identifier of at least one communication terminal.

[0094] In the specific implementation process of the present invention, the first signal cell sends a signal cell handover indication to the second signal cell and receives the signal cell handover confirmation feedback by the second signal cell based on the signal cell handover indication, including: The first signal cell generates the signal cell handover indication and sends the signal cell handover indication to the second signal cell; after the second signal cell receives the signal cell handover indication, the second signal cell prepares radio communication resources for the at least one communication terminal, generates the signal cell handover confirmation, and feeds back the signal cell handover confirmation to the first signal cell; the first signal cell receives the signal cell handover confirmation fed back by the second signal cell.

[0095] 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.

[0096] 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.

[0097] 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.

[0098] 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;

[0099] 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.

[0100] The first signal cell will generate a signal cell handover command according to the signal cell handover confirmation, where the signal cell handover command contains the communication terminal identifiers of at least one communication terminal; then send the signal cell handover command to at least one communication terminal simultaneously; and after at least one communication terminal receives the signal cell handover command, it will initiate a random access request to the second signal cell in the dual-mode base station simultaneously through the signal cell handover command and switch to the second signal cell according to the random access request; in this way, it is realized that at least one communication terminal can execute the handover process quickly in batches.

[0101] Release execution module 304: used to execute the UE context release of at least one communication terminal after at least one communication terminal switches to the second signal cell, and feedback the completion of UE release to the second signal cell.

[0102] In the specific implementation process of the present invention, the first signal cell executes the UE context release of at least one communication terminal and feedbacks the completion of UE release to the second signal cell, including: the second signal cell sends a UE context release notice to the first signal cell, and the UE context release notice carries the communication terminal identifiers of at least one communication terminal; after the first signal cell receives the UE context release notice, it executes the UE context release of at least one communication terminal based on the UE context release notice, and the UE context release is the radio resources of at least one communication terminal; the first signal cell feedbacks the completion of UE release to the second signal cell.

[0103] Specifically, the second signal cell sends a UE (User Equipment) context release notice to the first signal cell; after the first signal cell receives the UE context release notice, it will release the radio resources of the communication terminal corresponding to the UE context release notice; then reply a UE release completion to the second signal cell.

[0104] In the conventional handover process, the UE context release process is the last step in the entire handover process. Since the first signal cell and the second signal cell in the dual-mode base station in this embodiment belong to the same physical base station, signaling interaction can be completed internally, and by advancing this release process, the resource release of the first signal cell in the dual-mode base station is accelerated, thereby improving the handover execution efficiency.

[0105] Confirmation module 305: used to send a UE release completion and a core network handover completion notice from the second core network corresponding to the second signal cell 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 handover confirmation to the second core network based on the UE release completion and the core network handover completion notice.

[0106] In the specific implementation process of the present invention, the second core network corresponding to the second signal cell sends a UE release completion and core network handover completion notification to the first core network corresponding to the first signal cell, including: after at least one communication terminal switches to the second signal cell and the radio resources of at least one communication terminal on the first signal cell side are released, the second signal cell sends a UE release completion and core network handover notification to the second core network; the second core network performs a core network handover operation based on the core network handover notification, and obtains a core network handover completion notification when the second core network completes the core network handover operation; the second core network sends the UE release completion and the core network handover completion notification to the first core network corresponding to the first signal cell.

[0107] Further, the first core network returns a UE release confirmation and a core network handover completion confirmation to the second core network based on the UE release completion and core network handover completion notification, including: after the first core network receives the UE release completion and the core network handover completion notification, it performs a confirmation operation based on the UE release completion and the core network handover completion notification, and returns a UE release confirmation and a core network handover completion confirmation to the second core network.

[0108] Specifically, after at least one communication terminal switches to the second signal cell in the dual-mode base station and the radio 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 handover notification to the second core network corresponding to the second signal cell; 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 normally switched to the second signal cell side of the dual-mode base station.

[0109] Then the second core network will perform a core network handover operation according to the core network handover notification, and obtain a core network handover completion notification when the second core network completes the core network handover operation; the second core network sends the UE release completion and core network handover completion notification to the first core network corresponding to the first signal cell; to notify the first core network that these communication terminals have released the resources of the first signal cell and have switched to and accessed the second signal cell.

[0110] After the first core network receives the release completion and core network handover completion notification, it will perform a confirmation operation through the UE release completion and core network handover completion notification, and after completing the confirmation operation, return a UE release confirmation and a core network handover completion confirmation to the second core network; to inform the second core network that it is aware of the release of resources of these communication terminals and the situation of being switched and transferred.
