Description

Technical Field

[0001] The embodiments of the present application relate to the field of wireless communication technology, and in particular, to a method for identifying an idle terminal, a sentinel base station, and a readable storage medium. Background Art

[0002] In the field of communications, sentinel base stations have become an indispensable means for the refinement and intelligent evolution of services. Sentinel base stations are usually deployed at locations such as doorways and elevator entrances to monitor the traffic in the network coverage area. When the sentinel base station detects an increase in traffic, it wakes up other base stations in the network to provide network services to the terminals.

[0003] At present, sentinel base stations detect uplink SRS (Sounding Reference Signal) to determine whether there are terminal devices in the network coverage area, and then implement the next control strategy, such as energy saving. However, in the process of identifying idle terminals, the establishment and release of service traffic by sentinel base stations will occupy a large amount of signaling channel resources, which is easy to cause core network signaling storms and lead to network signaling congestion. Summary of the invention

[0004] The embodiments of the present application provide an idle terminal identification method, a sentinel base station and a readable storage medium, which are used to solve the problem in the related art that a large amount of signaling interaction is generated when identifying an idle terminal, causing network signaling congestion.

[0005] In a first aspect, an embodiment of the present application provides a method for identifying an idle terminal, which is applied to a sentinel base station, including:

[0006] In the case of being in monitoring mode, broadcasting a system information block; the system information block carries a sentinel mode information element, and the sentinel mode information element is used to instruct a terminal in an idle state within the network coverage area of ​​the sentinel base station to migrate to a connected state;

[0007] receiving a request message sent by the terminal after the terminal transitions from an idle state to a connected state;

[0008] According to a preset request message rejection mechanism, the request message of the terminal is rejected.

[0009] In a second aspect, an embodiment of the present application provides an idle terminal identification device, which is applied to a sentinel base station, including:

[0010] A broadcast module, configured to broadcast a system information block when in monitoring mode; the system information block carries a sentinel mode information element, and the sentinel mode information element is used to instruct a terminal in an idle state within a network coverage area of ​​the sentinel base station to migrate to a connected state;

[0011] A receiving module, used to receive a request message sent by the terminal after the terminal transitions from an idle state to a connected state;

[0012] The rejection module is used to reject the request message of the terminal according to a preset request message rejection mechanism.

[0013] In a third aspect, an embodiment of the present application provides a sentinel base station, comprising a processor and a memory, wherein the memory stores programs or instructions that can be executed on the processor, and when the program or instructions are executed by the processor, the steps of the method described in the first aspect above are implemented.

[0014] In a fourth aspect, an embodiment of the present application provides a readable storage medium, on which a program or instruction is stored. When the program or instruction is executed by a processor, the steps of the method described in the first aspect above are implemented.

[0015] The idle terminal identification method provided in the embodiment of the present application is applied to the sentinel base station. When in the monitoring mode, the system information block is broadcast; the system information block carries the sentinel mode element, and the sentinel mode element is used to instruct the terminals in the idle state within the network coverage area of ​​the sentinel base station to migrate to the connected state; the request message sent by the receiving terminal after the terminal migrates from the idle state to the connected state; and the request message of the terminal is rejected according to a pre-set request message rejection mechanism.

[0016] It can be seen that by adopting the method provided in the embodiment of the present application, the sentinel base station broadcasts a system information block carrying a sentinel mode element, so that the terminal in the idle state is migrated to the connected state, and rejects the request message after the terminal migrates from the idle state to the connected state. In this way, the signaling interaction caused by establishing or releasing service traffic during the service migration process can be reduced, and the signaling burden of the core network will not be increased, thereby avoiding the problem of network signaling congestion caused by excessive burden on the core network.

[0031] Exemplary embodiments will be described in detail herein, examples of which are shown in the accompanying drawings. When the following description refers to the drawings, the same numbers in different drawings represent the same or similar elements unless otherwise indicated. The implementations described in the following exemplary embodiments do not represent all implementations consistent with the present application. Instead, they are merely examples of devices and methods consistent with some aspects of the present application as detailed in the appended claims.

[0032] In some energy-saving scenarios in the communication field, such as digital indoor distribution and high-speed rail, the base station chooses to shut down the indoor distribution head end based on factors such as the real-time network load and the user distribution obtained by measurement. Only when there is no user distribution under the corresponding head end, can energy saving be truly achieved. At this time, the base station reserves some sentinel base stations (such as head ends in core locations such as doorways and elevator entrances) to monitor the traffic situation. When the sentinel station detects an increase in traffic, it triggers other head ends to wake up and shut down some head ends as needed to support coverage compensation. Therefore, for sentinel base stations, accurately identifying terminals within the network coverage area is conducive to timely adjustment of energy-saving strategies to ensure that the quality of network communications meets user needs.

[0033] However, if Figure 1 As shown, there is a bidirectional connection between the terminal in the connected state and the base station, and the base station can identify the existence of the terminal through uplink SRS (Sounding Reference Signal) and other methods, while there is only a unidirectional connection between the terminal in the idle state and the base station, and the base station can inform the terminal through a downlink broadcast message that there is no uplink link between the terminal and the base station.

[0034] In order to identify the terminal in the idle state, the relevant scheme proposes to configure different Tracking Area Codes (TAC) for the base station and the surrounding sites to trigger the uplink between the terminal and the base station. However, in the actual networking application process, this scheme is complex and the implementation effect is poor, which is easy to bring additional negative network effects. To this end, the embodiment of the present application provides an idle terminal identification method, which is applied to the sentinel base station, such as Figure 2 As shown, the idle terminal identification method 200 may include the following steps:

[0035] S201: In the case of being in monitoring mode, broadcasting a system information block; the system information block carries a sentinel mode information element, and the sentinel mode information element is used to instruct a terminal in an idle state within a network coverage area of ​​the sentinel base station to migrate to a connected state;

[0036] S202: receiving a request message sent by the terminal after the terminal transitions from an idle state to a connected state;

[0037] S203: Reject the request message of the terminal according to a preset request message rejection mechanism.

[0038] In the specific implementation, Figure 3As shown, the idle terminal moves from the ordinary cell to the sentinel cell (i.e., the network coverage area of ​​the sentinel base station). The sentinel base station broadcasts the system information block (SIB), for example, SIB1, SIB2, SIB3, etc. The system information block carries the sentinel mode signal element, which is used to instruct the idle terminal to migrate from the idle state to the connected state. The purpose of the migration is to enable the sentinel base station to identify the idle state service.

[0039] After the terminal is transferred from the idle state to the connected state, it sends a request message to the sentinel base station, such as a random access request message, a tracking area update request message, etc. The sentinel base station rejects the request message sent by the terminal according to the pre-set request message rejection mechanism. In this way, the signaling interaction caused by establishing or releasing service traffic during service migration can be reduced, and the signaling burden of the core network will not be increased, thereby avoiding the problem of network signaling congestion caused by excessive burden on the core network.

[0040] In the above step S201, the sentinel mode information element may be carried in the system information block in the following two possible implementation modes:

[0041] In a possible implementation, a sentinel mode information element is added based on the system information block. For example, the sentinel base station sends the sentinel mode information element through SIB1. When the terminal receives the broadcast message SIB1, it triggers the transition from the idle state to the connected state.

[0042] In another possible implementation, when the value of the target cell in the system information block is set to a predetermined value, the target cell is used to indicate a sentinel mode cell. Taking the system information block as SIB1 as an example, the target cell can be the TrackingAreaCode of the existing cell cellAccessRelatedInfo in SIB1, and the value of TrackingAreaCode is set to a predetermined value to indicate a sentinel mode cell. The target cell is also used to indicate other cells other than the sentinel mode cell, and the predetermined value is a value within the value range of the target cell and outside the value range of other cells. For example, for the above-mentioned TrackingAreaCode cell, the protocol defines its value range as BIT STRING (SIZE (24), which is used to indicate other cells other than the sentinel mode cell, and the sentinel mode cell can define the sentinel cell state by setting its value to FFFFF (HEX) or 0. When the terminal detects that the target cell is a predetermined value, it triggers the transition from the idle state to the connected state.

[0043] This is explained with specific examples. Figure 4As shown in the figure, in special network coverage scenarios such as sports stadiums, shopping malls, and high-speed railways, in order to reduce interference between cells and improve service adaptation in high-speed scenarios, multiple cells are usually merged into one cell, and multiple radio frequency units use the time and frequency resources of one cell to unify resource scheduling. Sentinel cells and ordinary cells use the same broadcast message, which can specifically include the following steps:

[0044] Step 1: The sentinel cell and the normal cell broadcast the same system message Cell1 / sib1, where the system message of the sentinel cell carries the sentinel mode information element;

[0045] Step 2: When the terminal moves from a normal cell to a sentinel cell, the terminal detects a sentinel mode cell, which triggers the migration from the idle state to the connected state;

[0046] Step 3: The terminal initiates a random access request to the service area in the sentinel cell, triggering the service sentinel service policy.

[0047] Here, the system message of the sentinel cell may be in the following form:

[0048] SIB1::=SEQUENCE{

[0049] …

[0050] Sentinel-Cell ENUMERATED{true}

[0051] }

[0052] Among them, Sentinel-Cell is a sentinel cell. When the terminal detects the system message, it triggers the transition from the idle state to the connected state.

[0053] Further, the sentinel base station receives a request message sent by the terminal after the terminal transitions from the idle state to the connected state. In a possible implementation manner, the request message includes a random access request message. In the above step S203, according to a preset request message rejection mechanism, rejecting the request message of the terminal device includes:

[0054] In response to the random access request message sent by the terminal, a rejection message is sent to the terminal, where the rejection message is used to indicate rejection of the random access request message of the terminal.

[0055] This is explained with specific examples. Figure 5 As shown, in the random access phase, the terminal UE initiates a random access request message (MSG1), and the sentinel base station gNB replies with a random access rejection (MSG2). In this way, the signaling interaction between the terminal UE and the 5G core network can be reduced, and the problem of network signaling congestion caused by excessive burden on the core network can be avoided.

[0056] In a possible implementation, the request message includes a tracking area update request message; in the above step S203, rejecting the request message of the terminal device according to a preset request message rejection mechanism includes:

[0057] The tracking area update request message is discarded, or a response message rejecting the tracking area update request message is returned to the terminal.

[0058] This is explained with specific examples. Figure 6 As shown, in the TAU process stage, in order to reduce the impact of the TAU process on the core network, especially to avoid network problems caused by signaling storms, the sentinel base station discards the tracking area update request message of the terminal, or returns a response message of rejecting the tracking area update request message to the terminal, so as to reduce the impact of the sentinel base station on the core network signaling storm and realize the core network unawareness.

[0059] In a possible implementation manner, in the above step S203, after rejecting the request message of the terminal device according to a preset request message rejection mechanism, the step further includes:

[0060] If the number of rejections of the request message exceeds a threshold within a preset time period, exiting the monitoring mode;

[0061] If the number of rejections of the request message within a preset time period does not exceed the number threshold, the communication network of the terminal is switched to the target network.

[0062] In the specific implementation, the sentinel base station counts the number of MSG2 and TAU failures within a preset time period (for example: time T1 = 10s). After the number of consecutive rejections of the request message exceeds N times (for example: N is 20 times), the sentinel base station exits the monitoring mode; otherwise, the sentinel base station actively migrates the user to the target network, for example, the 4G network, to ensure the effectiveness of the service.

[0063] In the above step S203, after rejecting the request message of the terminal device according to the preset request message rejection mechanism, the method further includes:

[0064] Sending a sentinel service notification message to an energy-saving base station in a target network where the sentinel base station is located; the sentinel service notification message is used to instruct the energy-saving base station to enter a wake-up activation state;

[0065] Receive the service notification confirmation message returned by the energy-saving base station.

[0066] In the specific implementation, Figure 7As shown, if the sentinel cell and the ordinary cell are in site mode, after the sentinel cell enters the sentinel monitoring mode, if the sentinel base station detects that the cell service status is active, it will notify the ordinary cell through the Xn / X2 port. After the ordinary cell detects the service, it adopts the corresponding network adjustment strategy. The specific steps are as follows:

[0067] Step 1: If the sentinel cell enters the sentinel monitoring mode, Cell1 / Sib1' containing the sentinel mode information element is sent to the terminal through broadcast;

[0068] Step 2: If the sentinel base station detects that a terminal has entered, it indicates that there is a service. At this time, the sentinel service notification message can be transmitted to the ordinary cell or other related sentinel cells through the Xn / X2 interface;

[0069] Step 3: After receiving the sentinel service notification message from the sentinel cell, the common cell or other associated sentinel cell enters the wake-up activation state, adopts an independent sentinel mode strategy, and replies a confirmation message to the sentinel base station.

[0070] In a possible implementation manner, the energy-saving base station includes a first energy-saving base station and a second energy-saving base station in adjacent network coverage areas; and sending a sentinel service notification message to an energy-saving base station in a target network where the sentinel base station is located includes:

[0071] A sentinel service notification message is sent to a first energy-saving base station in the target network where the sentinel base station is located. When the first energy-saving base station receives the sentinel service notification message, the sentinel service notification message is sent to the second energy-saving base station through the first energy-saving base station.

[0072] In the specific implementation, Figure 8 and Fig. 9 As shown, in the high-speed rail operation scenario, when the sentinel cell detects the arrival of a train, it sends an incoming train broadcast (i.e., a sentinel service notification message) to the first energy-saving base station in the target network where the sentinel base station is located. The energy-saving cell conducts train tracking inquiries, updates the operation status information of the high-speed rail, and sends the operation status information to the energy-saving neighboring cell to wake up the energy-saving neighboring cell and provide network services for the train.

[0073] In a possible implementation manner, in the above step S203, after sending the sentinel service notification message to the energy-saving base station in the target network where the sentinel base station is located, the step further includes:

[0074] The energy-saving base station periodically detects the number of terminals in the network coverage area;

[0075] When the number of the terminals does not exceed a preset number threshold, the system enters a dormant state.

[0076] In the specific implementation, Fig. 9 As shown in the figure, in the high-speed rail operation scenario, the energy-saving cell wakes up the cell according to the running status of all trains in the network coverage area, and makes load judgment every 2 seconds, and puts the carrier into sleep mode according to the departure status of each train. Fig.10 As shown, when the energy-saving base station detects that there are no users in the network coverage area, it enters a dormant state, and works normally when there are terminal users. At the same time, the head end on duty (such as the head end at core locations such as doorways and elevator entrances) is retained to monitor the traffic situation. When the sentinel station detects an increase in traffic, it triggers other head ends to wake up as needed.

[0077] The embodiment of the present application provides a method for identifying an idle terminal, which is applied to a sentinel base station. When in monitoring mode, a system information block is broadcast; the system information block carries a sentinel mode cell, which is used to instruct the terminal in the network coverage area of ​​the sentinel base station to migrate to a connected state; a request message sent by the receiving terminal after the terminal migrates from the idle state to the connected state; and the request message of the terminal is rejected according to a pre-set request message rejection mechanism. In this way, the signaling interaction caused by establishing or releasing service traffic during service migration can be reduced, and the signaling burden of the core network will not be increased, thereby avoiding the problem of network signaling congestion caused by excessive burden on the core network.

[0078] In addition, independent broadcasting in the sentinel cell working mode is beneficial to improving the strategy completeness and application promotion in the sentinel mode, providing strategic support for the subsequent network intelligence and refinement. At the same time, it ensures process optimization and reduces the impact of signaling storms on the core network. The function covers the full business sentinel mode, reduces the network's dependence on terminal status, and improves the completeness of network strategies.

[0083] Wherein, when the value of the target cell in the system information block is set to a predetermined value, the target cell is used to indicate the sentinel mode cell.

[0084] In a possible implementation, the target cell is also used to indicate other cells, where the other cells are cells other than the sentinel mode cell.

[0085] Optionally, the predetermined value is a value within a value range of the target cell and outside a value range of other cells.

2. The method according to claim 1, characterized in that In the case where the value of the target information element in the system information block is set to a predetermined value, the target information element is used to indicate the sentinel mode information element.

3. The method according to claim 2, characterized in that The target cell is also used to indicate other cells, where the other cells are cells other than the sentinel mode cell.

4. The method according to claim 3, characterized in that The predetermined value is a value within the value range of the target cell and outside the value range of the other cells.

5. The method according to any one of claims 1 to 4, characterized in that: The request message includes a random access request message; and the rejecting the request message of the terminal device according to a preset request message rejection mechanism includes: In response to the random access request message sent by the terminal, a rejection message is sent to the terminal, where the rejection message is used to indicate rejection of the random access request message of the terminal.

6. The method according to any one of claims 1 to 4, characterized in that: The request message includes a tracking area update request message; The step of rejecting the request message of the terminal device according to a preset request message rejection mechanism includes: The tracking area update request message is discarded, or a response message rejecting the tracking area update request message is returned to the terminal.

7. The method according to claim 1, characterized in that After rejecting the request message of the terminal device according to the preset request message rejection mechanism, the method further includes: If the number of rejections of the request message exceeds a threshold within a preset time period, exiting the monitoring mode; If the number of rejections of the request message within a preset time period does not exceed the number threshold, the communication network of the terminal is switched to the target network.

8. The method according to claim 1, characterized in that After rejecting the request message of the terminal device according to the preset request message rejection mechanism, the method further includes: Sending a sentinel service notification message to an energy-saving base station in a target network where the sentinel base station is located; the sentinel service notification message is used to instruct the energy-saving base station to enter a wake-up activation state; Receive the service notification confirmation message returned by the energy-saving base station.

9. The method according to claim 8, characterized in that The energy-saving base station includes a first energy-saving base station and a second energy-saving base station in adjacent network coverage areas; and sending a sentinel service notification message to an energy-saving base station in a target network where the sentinel base station is located includes: A sentinel service notification message is sent to a first energy-saving base station in the target network where the sentinel base station is located. When the first energy-saving base station receives the sentinel service notification message, the sentinel service notification message is sent to the second energy-saving base station through the first energy-saving base station.

10.
