[0002] At present, the fifth generation mobile communication technology (5G) has added a new radio resource control inactive state (Radio Resource Control inactive, RRC_INACTIVE), that is, the RRC inactive state. For terminal equipment scenarios with low business or no low latency requirements, the access network equipment will directly let the terminal device enter the RRC inactive state based on the basic strategy (the inactive state switch is turned on by default) and retain the context session of the terminal device on the GNB-AMF side.

[0003] In this terminal device scenario, considering that a large number of terminal devices have no business behavior and rapid recovery requirements during the night period, they enter the RRC inactive state, resulting in an excessive number of context sessions retained by the access network equipment, a large amount of network resources wasted, and excessive power consumption.

[0026] Figure 1 It is a flow chart of a method for controlling a radio resource control RRC state provided according to an embodiment of the present invention. The method for controlling a radio resource control RRC state is applied to a control device for a radio resource control RRC state. The control device for the radio resource control RRC state in this embodiment is implemented by software and / or hardware. The control device for the radio resource control RRC state in this embodiment can be configured in an access network device.

[0027] like Figure 1 As shown, the control method of the radio resource control RRC state may include:

[0028] Step 101, within a specified time period of the access network device, for a terminal device in an RRC inactive state accessed by the access network device, monitor the RRC connection recovery process for the terminal device.

[0029] In an embodiment of the present invention, in one example, during a specified time period of the access network device, most of the terminal devices or multiple terminal devices accessed by the access network device may have no business behavior or no rapid recovery demand. In another example, during a specified time period of the access network device, the terminal devices accessed by the access network device are likely to have no business behavior or have no rapid recovery demand.

[0030] The specified time period may be set based on experience or determined based on historical behavior data of the terminal device accessed by the access network device. The specified time period may be, for example, a night time period.

[0031] In the embodiment of the present invention, the access network device may be provided with an RRC state control switch, and the RRC state control switch is in the on state. That is, before step 101, the access network device may also perform the following process: (1) determine whether the access network device is provided with an RRC state control switch; (2) if the access network device is not provided with an RRC state control switch, the default may be to perform real-time Figure 1 Each step in the embodiment shown; (3) if the access network device is provided with an RRC state control switch, and the RRC state control switch is in the closed state, then stop executing Figure 1 (4) If the access network device is provided with an RRC state control switch, and the RRC state control switch is in the on state, then execute Figure 1 The various steps in the illustrated embodiment.

[0032] Among them, when the RRC state control switch is in the off state, the access network device may have at least one of the following situations: the number of terminal devices connected to the access network device may be small, or the proportion of terminal devices in the RRC inactive state on the access network device may be small, etc., which does not affect the service experience of the terminal devices with low latency requirements connected to the access network device.

[0033] Among them, when the RRC state control switch is in the on state, the access network device may have at least one of the following situations: the number of terminal devices connected to the access network device is too large, or the proportion of terminal devices in the RRC inactive state on the access network device is large, etc., which may affect the service experience of the terminal device with low latency requirements connected to the terminal device.

[0034] Step 102, when an RRC connection recovery process is monitored and the recovery reason of the RRC connection recovery process is a notification area update, determine whether the terminal device meets the entry conditions of the RRC inactive state.

[0035] In an embodiment of the present invention, the recovery reason is the RRC connection recovery process of notifying the area update, which means that when the terminal device is in the RRC inactive state, the terminal device can move within the area configured by the access network device without notifying the access network device; when the terminal device moves out of the area configured by the access network device, the terminal device can initiate the RRC connection recovery process and enter the RRC connected state to perform area update processing; after the area update is completed, when the terminal device meets the entry conditions of the RRC inactive state, the access network device can control the terminal device to switch from the RRC connected state to the RRC inactive state.

[0036] In an embodiment of the present invention, the conditions for entering the RRC inactive state may include at least one of the following: (1) the access network device turns on the relevant switch of the RRC inactive state and configures the timer; (2) the terminal device capability supports the RRC inactive state; (3) the terminal device context carries core network assistance information (Core Network Assistance Information); (4) the terminal device has no business for a period of time, triggering the RRC connection release process.

[0037] In an embodiment of the present invention, the access network device may also perform the following process: when an RRC connection recovery process is monitored and the recovery reason of the RRC connection recovery process is other reasons other than the notification area update, determine whether the terminal device meets the entry conditions; if the terminal device meets the entry conditions, control the terminal device to enter the RRC inactive state.

[0038] Among them, for a terminal device connected to the access network device, if the terminal device is in the RRC inactive state and monitors the RRC connection recovery process with the recovery reason being other than the notification area update, it means that there may be business on the terminal device, rather than no business for a period of time. In this case, if the terminal device meets the entry conditions of the RRC inactive state again, the context session needs to be retained for the terminal device, so the terminal device can be controlled to enter the RRC inactive state.

[0039] Step 103, when the terminal device meets the entry conditions, control the terminal device to enter the RRC idle state.

[0040] In an embodiment of the present invention, for a terminal device accessed by an access network device, if the terminal device is in an RRC inactive state and then monitors that the recovery cause is an RRC connection recovery process notifying an area update, and then the terminal device meets the conditions for entering the RRC inactive state again, it means that the terminal device may have no business for a period of time, and the RRC connection recovery will only be performed when the area is updated. In this case, there is no need to retain the context session for the terminal device, and the terminal device can be directly controlled to enter the RRC idle state.

[0041] In an embodiment of the present invention, the access network device may further perform the following process: within a non-specified time period of the access network device, for terminal devices in an RRC inactive state accessed by the access network device, obtain the current connection proportion of the access network device; the current connection proportion is the ratio of the number of terminal devices currently accessed by the access network device to a specified number threshold; the specified number threshold is the maximum number of terminal devices supported for access by the access network device; when the current connection proportion is greater than or equal to the first proportion threshold, control the terminal device to enter an RRC idle state.

[0042] In addition, the access network device may also perform the following process: when the current connection proportion is less than the first proportion threshold, control the terminal device to maintain the RRC inactive state.

[0043] Among them, in the non-specified time period of the access network, in one example, most of the terminal devices or multiple terminal devices accessed by the access network device may have business behaviors, or have a demand for rapid recovery. In another example, in the non-specified time period of the access network, the terminal devices accessed by the access network device are likely to have business behaviors, or have a demand for rapid recovery. Among them, the non-specified time period of the access network refers to other time periods within a certain time period except the specified time period. Among them, a certain time period, for example, includes a 24-hour time period or a 12-hour time period every day.

[0044] Among them, when the current connection proportion of the access network device is greater than or equal to the first proportion threshold, it means that the number of terminal devices accessed by the access network device is large, and the number of remaining terminal devices that the access network device can access is small. At this time, the number of terminal devices accessed by the access network device is close to saturation. At this time, if the context session is retained for the terminal device that meets the entry conditions of the RRC inactive state, it may affect the service experience of other terminal devices. Therefore, the terminal device can be controlled to enter the RRC idle state.

[0045] Among them, when the current connection proportion of the access network device is less than the first proportion threshold, it means that the number of terminal devices accessed by the access network device is not close to saturation, and the access network device still has relatively more network resources. At this time, for the terminal devices that meet the entry conditions of the RRC inactive state, the context session is retained and will not affect the service experience of other terminal devices. Therefore, the terminal device can be controlled to maintain the RRC inactive state.

[0046] The control method of the wireless resource control RRC state of the embodiment of the present invention monitors the RRC connection recovery process for the terminal device in the RRC inactive state accessed by the access network device within a specified time period of the access network device; when the RRC connection recovery process is monitored and the recovery reason of the RRC connection recovery process is a notification area update, determines whether the terminal device meets the entry condition of the RRC inactive state; when the terminal device meets the entry condition, controls the terminal device to enter the RRC idle state, so that the terminal device with no business behavior and rapid recovery requirements during the night time period can be controlled to enter the RRC idle state, thereby reducing the number of context sessions retained by the access network device, avoiding network resource waste, and reducing the power consumption of the access network device.

[0047] Figure 2 It is a flowchart of another method for controlling the RRC state of a radio resource control provided according to an embodiment of the present invention.

[0048] like Figure 2 As shown, in Figure 1 Based on the illustrated embodiment, the method for controlling the radio resource control RRC state may further include:

[0049] Step 201: Obtain a specified time period of an access network device.

[0050] In the embodiment of the present invention, if the designated time period of the access network device is not obtained, the initial time period may be used as the designated time period of the access network device.

[0051] Step 202, when the specified time period is the initial time period, obtain the behavior data of at least one terminal device in the RRC inactive state accessed by the access network device within the preset time period, the behavior data including: whether the terminal device has active data link establishment behavior, and the occurrence time of the active data link establishment behavior.

[0052] In the embodiment of the present invention, the terminal device has an active data link establishment behavior, which means that the terminal device initiates the reconstruction of the RRC connection, and the reason for the reconstruction of the RRC connection is that the terminal device needs to transmit data. Among them, the request initiated by the terminal device to reconstruct the RRC connection will carry the connection reason. Among them, the occurrence time of the active data link establishment behavior can be the time when the terminal device initiates the reconstruction of the RRC connection.

[0053] In the embodiment of the present invention, the preset time period may be, for example, 3 days, n hours, etc., and may be set according to actual needs.

[0054] Step 203: update the designated time period of the access network device according to the behavior data of at least one terminal device.

[0055] In an embodiment of the present invention, the process of the access network device executing step 203 may, for example, be as follows: determining, based on the behavior data of at least one terminal device, a first terminal device in at least one terminal device that does not have active data link establishment behavior, and a second terminal device in at least one terminal device that has active data link establishment behavior; determining a state retention time period based on a time period when the first terminal device is in an RRC inactive state; determining, based on the occurrence time of the active data link establishment behavior of the second terminal device, whether there is a state interruption time period that meets specified conditions within a preset time period; if there is no state interruption time period within the preset time period, or if the state interruption time period is not included in the state retention time period, updating the specified time period of the access network device according to the state retention time period; if there is a state interruption time period within the preset time period, and the state interruption time period is included in the state retention time period, updating the specified time period of the access network device according to the non-state interruption time period within the state retention time period.

[0056] Among them, the specified conditions satisfied by the status interruption time period include at least one of the following: the duration of the active data link establishment behavior of the second terminal device within the status interruption time period is less than the preset duration threshold; the ratio of the number of second terminal devices to the number of at least one terminal device within the status interruption time period is greater than the second proportion threshold.

[0057] Among them, the process of the access network device determining the state retention time period according to the time period when the first terminal device is in the RRC inactive state can be, for example, when there is only one first terminal device, directly using the time period when the first terminal device is in the RRC inactive state as the state retention time period. When there are multiple first terminal devices, the time period when each first terminal device is in the RRC inactive state can be obtained separately; the intersection of the multiple time periods, that is, the overlapping time period, is used as the state retention time period.

[0058] It should be noted that if the state retention time period is not obtained, it is determined that the access network device does not exist in the specified time period.

[0059] Among them, the process of the access network device determining the status interruption time period based on the occurrence time of the active data link establishment behavior of the second terminal device can be, for example, as follows: (1) obtaining a candidate time period, wherein the occurrence duration of the active data link establishment behavior of each second terminal device within the candidate time period is less than a preset time threshold; (2) if the candidate time period is not obtained, determining that there is no status interruption time period within the preset time period; (3) if the candidate time period is obtained, obtaining the number of second terminal devices within the candidate time period, and obtaining the total number of terminal devices connected to the access network device (i.e., the number of at least one terminal device); obtaining the ratio of the two numbers; when the ratio is greater than the second proportion threshold, using the candidate time period as the status interruption time period; when the ratio is less than or equal to the second proportion threshold, stopping using the candidate time period as the status interruption time period.

[0060] The second percentage threshold may be, for example, 30%, etc. The preset duration threshold may be, for example, 5 minutes, etc.

[0061] In the embodiment of the present invention, the execution order of step 201 to step 203 is not limited to Figure 1 Before which step in, or after which step in. If steps 201 to 203 are performed before step 101, the specified time period in step 101 may be an updated specified time period determined based on steps 201 to 203. If steps 201 to 203 are performed after step 101, the specified time period in step 101 may be an initial time period.

[0062] In addition, after step 203, when the access network device needs to execute steps 201 to 203 again, it can use the initial time period to replace the specified time period, so that the access network device can re-execute steps 201 to 203, and re-determine the specified time period based on the behavior data of at least one terminal device in the RRC inactive state accessed by the access network device within the latest time period.

[0063] Among them, since the terminal devices accessed by the access network device may change over time, and the active data link establishment behavior of the accessed terminal devices may also change over time, the previously determined designated time period may not be applicable to the current time. Therefore, it is necessary to re-combine the behavior data of at least one terminal device in the RRC inactive state accessed by the access network device within a preset time period after the current time to determine the latest designated time period, improve the applicability of the designated time period, and further reduce the waste of network resources and reduce the power consumption of access network equipment.

[0064] The control method of the wireless resource control RRC state of the embodiment of the present invention obtains the specified time period of the access network device; when the specified time period is the initial time period, obtains the behavior data of at least one terminal device in the RRC inactive state accessed by the access network device within the preset time period, and the behavior data includes: whether the terminal device has active data link establishment behavior, and the occurrence time of the active data link establishment behavior; according to the behavior data of at least one terminal device, the specified time period of the access network device is updated and processed, so that the specified time period of the access network device can be accurately determined, and then based on the specified time period, for the terminal device with no business behavior and rapid recovery requirements during the night time period, the terminal device is controlled to enter the RRC idle state, thereby reducing the number of context sessions retained by the access network device, avoiding network resource waste, and reducing the power consumption of the access network device.

[0065] The following examples are used to illustrate this. Figure 3 The figure shows a schematic diagram of determining the designated time period of the access network equipment. Figure 3 In the process of determining the designated time period of the access network device, the following steps may be included: (1) The base station (access network device) turns on the real inactive judgment switch (RRC state control switch). (2) The GNB (access network device) collects all UE information (behavior data of the terminal device) that enters the inactive state (RRC inactive state) within a 24h*3 period, and determines whether mo_data (active data link establishment behavior) is active after inactive; if so, execute (3); if not, execute (4). (3) The time c when active mo_data occurs under inactive (the time period when the first terminal device is in the RRC inactive state). (4) The time period A to B when there is no mo_data behavior under inactive (the state retention time period). (5) Take the intersection of time c and time period A to B to obtain the intersection result. (6) If the intersection result is that time c does not belong to time period A to B, then select A to B as the tidal time period (designated time period). (7) If the intersection result is that time c belongs to the A-B period, and the number of UEs at time c is greater than 30% of the total inactive UEs, and the active duration of UEs at time c is less than 5 minutes, then the earliest C1 and the latest C2 in the A-B period are removed to generate two specified time periods A-C1 and C2-B; if the intersection result is that time c belongs to the A-B period, and at least one of the above two conditions is not met at time c, then it is considered that time c does not belong to the A-B period.

[0066] The following examples are used to illustrate this. Figure 4 The figure shows the control diagram of the RRC state. Figure 4In the RRC state control process, the following steps may be included: (1) The UE (terminal device) has no service that satisfies the inactive detection period (i.e., the terminal device is in the RRC inactive state). (2) Whether the GNB (access network device) is in the tidal period and the real inactive judgment switch (RRC state control switch) is turned on; if so, execute (3); if not, execute (7). (3) Enter inactive for the first time, and then execute (4). (4) During Resume recovery (RRC connection recovery process), determine whether the cause value is RAU update (notification area update); if so, execute (5); if not, execute (6). (5) After RAU, there is no service again that satisfies the inactive period (meets the entry conditions of the RRC inactive state), and the context is released to enter RRC_IDLE (RRC idle state). (6) The UE enters the inactive state (RRC inactive state). (7) Determine whether the number of UEs connected to the current base station (access network device) is greater than 80% of the maximum number of connections; if so, execute (8); if not, execute (6). (8) Release the UE context and enter RRC_IDLE.

[0069] Transceiver 500, processor 510, memory 520, wherein:

[0070] The transceiver 500 is used to receive and send data under the control of the processor 510 .

[0071] Among them, Figure 5In the embodiment, the bus architecture may include any number of interconnected buses and bridges, specifically linking together various circuits of one or more processors represented by processor 510 and memory represented by memory 520. The bus architecture may also link together various other circuits such as peripherals, voltage regulators, and power management circuits, which are well known in the art and are therefore not further described herein. The bus interface provides an interface. The transceiver 500 may be a plurality of components, namely, a transmitter and a receiver, providing a unit for communicating with various other devices on a transmission medium, which transmission medium may include a wireless channel, a wired channel, an optical cable, and the like. The processor 510 is responsible for managing the bus architecture and general processing, and the memory 520 may store data used by the processor 510 when performing operations.
