At present, when terminal equipment conducts webpage browsing, instant messaging, games, videos and the like, the power consumption is usually increased more than that of some simple calls or data services, so that the UE and the network equipment are enabled to cooperate with the UE to execute a corresponding energy-saving strategy, and the power consumption of the UE is imperative to be reduced. In the current energy-saving configuration method, the RAN generally configures the energy-saving policy for the UE, and since the number of RANs is massive, it is not beneficial to centralized management and control.

Therefore, the embodiment of the application provides an energy-saving configuration method, which can configure an energy-saving strategy for the UE, so as to reduce the power consumption of the UE. In the embodiment of the present application, the AMF or PCF, etc. may specifically configure the energy saving policy for the UE, thereby facilitating centralized management and control of the energy saving policy. The following description will be divided into different embodiments for separate description.

Example one

As shown in fig. 2, an embodiment of the present application provides an energy saving configuration method, including:

step 200: and the AMF network element determines an energy-saving strategy. The energy saving strategy may include, but is not limited to, at least one of: an energy saving policy of the UE, an energy saving policy of the RAN, or an energy saving policy of the AMF, etc. It should be noted that the above-mentioned UE energy-saving policy, RAN energy-saving policy or AMF energy-saving policy are essentially configured energy-saving policies for the UE, except that the UE energy-saving policy may require cooperation of the RAN or AMF.

For example, the energy saving strategy may include at least one energy saving method, where each energy saving method includes an identifier of the energy saving method and a parameter corresponding to the energy saving method. For example, the energy saving strategy includes energy saving method 1 to energy saving method n. If the energy saving method 1 requires configuration of the RAN and the AMF, the energy saving policy of the UE may include: an identifier and a parameter 1 of the energy saving method 1, where the parameter 1 is a parameter that needs to be configured to the UE when the UE executes the energy saving method 1. The energy-saving policy of the RAN may include: an identifier of the energy saving method 1 and a parameter 2, where the parameter 2 is a parameter that needs to be configured to the RAN when the UE performs the energy saving method 1. The energy-saving strategy of the AMF may include: an identifier of the energy saving method 1 and a parameter 3, where the parameter 3 is a parameter that needs to be configured to the AMF when the UE performs the energy saving method 1.

In one implementation, the AMF may determine the energy saving policy according to the capability of the UE. For example, for some energy saving methods, the UE may not support, the energy saving policy configured for the UE may not include the energy saving method, and the AMF may obtain the capability of the UE and determine the energy saving policy according to the capability of the UE.

Step 201: the AMF sends indication information of the energy-saving strategy to the RAN. Optionally, the indication information of the power saving policy may be carried in the N2 message. The energy saving policy includes at least one energy saving method, and the indication information of the energy saving policy may include: the name of each energy-saving method in the energy-saving strategy and the corresponding parameter of each energy-saving method.

For example, as shown in table 1, if n energy saving methods are included in the energy saving policy, the indexes of the n energy saving methods are 1 to n in sequence. The energy saving method 1 may be Discontinuous Reception (DRX), the energy saving method 2 may be Wake Up Signal (WUS), and the energy saving method n may be Radio Resource Management (RRM). Each energy saving method has corresponding parameters, for example, the parameters corresponding to DRX include InactivityTimer, LongCycleTimer, ShortCycleTimer, etc., and the parameters corresponding to WUS include WUS auxiliary information, etc.

TABLE 1

In the following, DRX, WUS, etc. are exemplarily described.

The DRX mechanism may refer to that the UE periodically enters a sleep mode at some time, and in the sleep mode, the UE does not need to monitor the PDCCH, and when monitoring is needed, the UE wakes up from the sleep mode, thereby achieving the purpose of saving power. Timers associated with the DRX mechanism may include inactivity timers (inactivity timers), long cycle timers (long cycle timers), short cycle timers (short cycle timers), and the like. For example, the UE may continue to monitor the PDCCH during the operation of the inactivity timer without being controlled by the DRX cycle, thereby avoiding missed listening. The long period timer and the short period timer are timers introduced to further reduce the power consumption of the UE. For example, during the operation of the long cycle timer, the UE may perform a DRX long cycle, while during the operation of the short cycle timer, the UE may perform a DRX short cycle, and so on.

WUS may refer to a signal having a wake-up function. The UE in the sleep state may be woken up using the WUS signal. Due to the adoption of the WUS technology, the UE is allowed to be in a dormant state, so that the power consumption of the UE is reduced. Among them, the WUS may instruct the UE to receive, monitor, detect, or listen (detect) Downlink Control Information (DCI) for scheduling a paging message in one or more Paging Occasions (POs), that is, paging DCI. Alternatively, it may be described that WUS is used to indicate that DCI for paging is monitored in PO, or it may be described that WUS is used to indicate whether DCI for paging is monitored in PO, etc. The UE receives the WUS and may assume that the UE is woken up by the WUS. The wake-up signal may also be referred to as a wake-up signal, or an activation signal, etc. Exemplary parameters related to the WUS power save method include: WUS assistance information (association information).

In this embodiment of the present application, if the energy saving policy includes an energy saving policy of the AMF, the AMF may execute a corresponding energy saving operation according to the indication information of the energy saving policy. If the energy-saving policy includes an energy-saving policy of the UE, the process shown in fig. 2 may further include the following optional steps:

step 202: the RAN sends an RRC message to the UE, wherein the RRC message can be an RRC reconfiguration message and is used for configuring an energy-saving strategy of the UE;

step 203: the UE sends UE auxiliary information to the RAN, and the UE auxiliary information is used for informing the RAN that the UE completes energy-saving configuration.

Step 204: the RAN sends an indication that the power saving configuration is complete to the AMF.

By the method, the energy-saving strategy of the UE can be configured by the AMF, and the centralized management and control of the energy-saving strategy are easy.

Example two

As shown in fig. 3, an embodiment of the present application further provides an energy saving method, and compared with the energy saving configuration method shown in fig. 2 in the first embodiment, the configuration of the energy saving policy may be moved to the PCF, and the PCF performs the configuration of the energy saving policy.

At least comprises the following steps:

step 300: and the AMF reports the capability of the UE to the PCF. For example, the AMF may send an indication of the UE capabilities to the PCF. For example, the UE may report the UE capability to the AMF during the initial access procedure. For example, the UE may report the capability of the UE to the AMF through a UE capability message or a UE radio capability message.

Step 301: the PCF determines an energy-saving strategy, which may include at least one of the following: an energy saving policy of the UE, an energy saving policy of the RAN, or an energy saving policy of the AMF, etc.

Illustratively, the PCF may determine the power-saving policy based at least on the capabilities of the UE. Further, the PCF may determine the energy saving policy according to other information (e.g., subscription information) of the UE and the capability of the UE. For example, for some energy saving methods, the capability of the UE may support, but the UE may not sign the energy saving method, and the PCF may not configure the energy saving method for the UE in the energy saving policy. Optionally, the PCF may interact with the UDM, and the like, and obtain information of the UE for determining the energy saving policy, for example, information of access authorization control and subscription data management of the UE, to determine the capability of the UE.

Step 302: the PCF sends the indication information of the energy-saving strategy to the AMF. For example, the PCF may send a policy control update notification (policy control update notification) or the like to the AMF, and the policy control update notification may include indication information of the energy saving policy.

If the energy-saving strategy comprises the energy-saving strategy of the AMF, the AMF can execute corresponding energy-saving operation according to the indication of the energy-saving strategy of the AMF. Or the energy saving policy includes an energy saving policy of the RAN and/or an energy saving policy of the UE, the process shown in fig. 3 may further include the following steps:

step 303: the AMF sends the RAN an energy saving policy of the RAN and/or an energy saving policy of the UE. For example, the AMF may send an N2 message to the RAN, the N2 message including indication information of the energy saving policy of the RAN and/or the energy saving policy of the UE. If the energy-saving policy includes the energy-saving policy of the RAN, the RAN may perform a corresponding energy-saving operation according to the indication information of the energy-saving policy of the RAN.

If the energy saving policy includes an energy saving policy of the UE, the process shown in fig. 3 may further include the following steps:

step 304: the RAN sends an RRC message to the UE, where the RRC message may be an RRC reconfiguration message that includes indication information of an energy saving policy of the UE. The UE may perform a corresponding energy saving operation according to the energy saving policy of the UE.

Step 305: and the UE sends a UE auxiliary message to the RAN, wherein the UE auxiliary message comprises indication information of the completion of the UE configuration energy-saving strategy.

Step 306: the RAN sends an N2 message to the AMF, which N2 message is a notification message for notifying the AMF of the completion of the configuration of the energy saving policy, etc.

As shown in fig. 4, an embodiment of the present application further provides an energy saving configuration method, where the configuration method is different from the method shown in fig. 3, in that a PCF may directly configure an energy saving policy for a UE, including:

step 400: and the AMF reports the capability of the UE to the PCF.

Step 401: the PCF determines the power saving policy based on the capabilities of the UE by interacting with the UDR. The energy-saving strategy at least comprises the energy-saving strategy of the UE.

Step 402: the PCF sends indication information of the energy-saving strategy of the UE to the UE. For example, the PCF may send a non-access stratum (NAS) message to the UE, where the NAS message may carry indication information of the energy saving policy of the UE, and the NAS message may be an N1 message, such as a UE configuration update command (UE configuration update command), or the like.

Step 403: the UE sends a notification message of energy saving configuration completion to the PCF, where the notification message may also be carried in a NAS message, and the NAS message may be an N1 message, for example, a configuration update complete (configuration update complete) message. Step 403 is an optional step, and step 403 may not be executed here, and step 404 described below is executed directly after step 402 is executed.

If the energy saving policy determined by the PCF in step 401 further includes an energy saving policy of the AMF and/or an energy saving policy of the RAN. The above flow in fig. 4 may further include the following steps:

step 404: the PCF sends the AMF an indication of the energy saving policy of the AMF and/or the energy saving policy of the RNA. For example, the PCF may send an AM policy control update notification (AM policy control update notification) to the AMF, where the notification may carry indication information of the energy saving policy of the AMF and/or the energy saving policy of the RAN.

Step 405: the AMF transmits an N2 message to the RAN, the N2 message including indication information of the power saving policy of the RAN. For example, the AMF may send an N2 message to the RAN, where the N2 message carries information indicating the power saving policy of the RAN.

The flow shown in fig. 4 may further include the following optional steps:

step 406: the RAN sends an RRC message to the UE, which may include information indicating the N2 energy saving methods.

Step 407: and the UE sends UE auxiliary information to the RAN, wherein the auxiliary information is used for informing the RAN of the completion of the energy-saving strategy configuration.

Step 408: the RAN sends an N2 message to the AMF, which N2 message is used to inform the AMF that the energy saving policy configuration is complete.

In the embodiment shown in fig. 4, the UE may be configured with the energy-saving policy in two ways. For example, the energy saving strategy of the UE includes N energy saving methods, and the N energy saving methods are divided into two parts, which are N1 energy saving methods and N2 energy saving methods, respectively. For the above N1 energy saving methods, the NAS messages in step 402 and step 403 in fig. 4 may be configured to the UE. The remaining N2 power saving methods may be configured by the RAN to the UE as described above with reference to steps 405 and 406 in fig. 4.

EXAMPLE III

In the process, a first network element may unify service orchestration and configure an energy-saving policy to PCF, AMF, RAN, or the like, and the first network element may be a module or a network element for managing a terminal device. The first network element may be a network element in which a terminal management module is deployed, and the terminal management module may be deployed alone, or may be deployed on network elements such as NEF or AMF. In the following description, the first network element is taken as an example of a terminal management module. As shown in fig. 5, includes:

step 501: third party application (3)^rd application，3^rdAPP) may transmit indication information of the energy saving mode to the terminal management module.

In an embodiment of the present application, the energy saving mode may include at least one of: the power saving mode, the auto power saving mode, or the extreme performance mode can be referred to table 2 for the description of the power saving mode.

TABLE 2

In the examples of the present application, 3^rdThe APP may send, to the terminal management module, indication information of a power saving mode currently required to be adopted by the UE, through an application interface (API). In aIn understanding 3^rdThe APP may be an application program of a server that manages the UE. For example, if the UE is a smart grid terminal, the 3rd APP may be an application program corresponding to a server that manages the smart grid terminal, and the application program may receive an indication of a user (the user may be an administrator of the smart grid terminal), determine what power saving mode is adopted by the current smart grid, and send indication information of the corresponding power saving mode to the terminal management module through the API interface.

Step 502: the terminal management module determines an energy-saving strategy according to the indication information of the energy-saving mode, wherein the energy-saving strategy comprises at least one of the following items: an energy-saving policy of the UE, an energy-saving policy of the AMF, or an energy-saving policy of the RAN, etc.

In this embodiment, the terminal management module may perform service arrangement according to the indication information of the energy saving mode and in combination with at least one of information such as the capability of the UE, the network capability, or the network state, and determine the energy saving policy. For example, the terminal management module may service-code the power saving method based on at least one of the above information, determine that the very power saving mode includes the power saving methods 1 to M1, the automatic power saving mode includes the power saving methods M2 to M3, the very performance mode includes the power saving method M4, and the like. For example, if the power saving mode indicated by the 3rd APP through the API interface is the very power saving mode, the power saving policy determined by the terminal management module includes power saving methods 1 to M1. It is understood that the aforementioned power saving methods 1 to M1 may require cooperation of the RAN and the AMF, etc., and thus, the power saving policies may further include power saving policies that the RAN and the AMF need to execute, etc.

In a possible design, the terminal management module may call an interface of the AMF network element, and send the indication information of the energy saving policy to the AMF network element. The configuration of the power saving policy is subsequently performed by the AMF. For example, the flow shown in fig. 5 may further include: step 503 a: and the terminal management module sends a configuration terminal energy-saving-service message to the AMF, wherein the configuration terminal energy-saving-service message comprises indication information of an energy-saving strategy. For the subsequent process of configuring the energy saving policy by the AMF, reference may be made to the description in the first embodiment. It should be noted that, in this embodiment of the application, when receiving the indication information of the energy saving policy, the AMF network element may directly send the indication information of the energy saving policy to the RAN. Or, the AMF network element may further process the energy saving policy received from the first network element and forward the energy saving policy to the RAN. For example, the AMF network element refers to the energy saving policy received from the first network element as a first energy saving policy. The AMF network element may process the first energy saving policy to obtain a second energy saving policy; and the AMF network element sends the indication information of the second energy-saving strategy to the access network equipment.

In another possible design, the terminal management module may further invoke an interface of the PCF to send the indication information of the energy saving policy to the PCF. The configuration of the power saving policy is subsequently performed by the PCF. For example, the flow shown in fig. 5 may further include: step 503 b: the terminal management module sends an update (update) message to the UDR, the update message including indication information of the energy saving policy. Step 504 b: the UDR sends a notification (notify) message to the PCF, the notification message for sending an indication of the power saving policy to the PCF. The process of the PCF configuring the energy saving policy can be seen from the description in the second embodiment. It should be noted that, in this embodiment of the present application, when receiving the indication information of the energy saving policy, the PCF network element may directly send the indication information of the energy saving policy to the AMF or the UE. Or the PCF network element may further process the energy saving policy received from the first network element and forward it to the AMF or the UE. For example, the power saving policy received from the first network element is referred to as a first power saving policy. The PCF network element may process the first energy saving policy to obtain a second energy saving policy; and the PCF network element sends the indication information of the second energy-saving strategy to the AMF or the UE.

In another possible design, the terminal management module may further invoke an interface of the RAN to send the indication information of the energy saving policy to the RAN. For example, the flow shown in fig. 5 may further include: step 503 c: and the terminal management module sends a configuration terminal energy-saving message to the RAN, wherein the configuration terminal energy-saving message comprises indication information of an energy-saving strategy. Step 504 c: and the RAN sends an RRC message to the UE, wherein the RRC message comprises indication information of the energy-saving strategy.

In this embodiment, the third-party application may directly indicate the energy-saving mode to the terminal management module, and the terminal management module performs service arrangement according to the indicated energy-saving mode and other information, determines an energy-saving policy, and then configures the energy-saving policy for the UE. Since the energy saving method is complex and has high professional degree, in the embodiment of the application, the energy saving mode is directly displayed in the third-party application program without displaying the complex energy saving method, and the user of the third-party application program can directly select the energy saving mode without having a high professional level. After the user selects the energy-saving mode, the terminal management module can perform service arrangement, determine an energy-saving strategy, configure the energy-saving strategy to the UE, is easy to implement, and can effectively reduce the complexity of the user.

In a third embodiment, a schematic diagram of a network architecture is further provided, as shown in fig. 6, including:

3^rdthe APP sends indication information of an energy-saving mode to the terminal management module through the API, and the energy-saving mode can comprise an extremely power-saving mode, an automatic power-saving mode or an extremely performance mode and the like. Service management module may be according to 3^rdAnd the energy-saving mode indicated by the APP performs service arrangement, and determines an energy-saving strategy corresponding to the current power-saving mode. The energy saving policy at least includes AN energy saving policy of the UE, AN energy saving policy of the RAN (which may be referred to as AN energy saving policy of the AN), AN energy saving policy of the AMF (which may be referred to as AN energy saving policy of the AM), and the like.

Regarding the energy saving policy of the UE, the terminal management module may send the energy saving policy of the UE to the PCF through the UDR, and the PCF may directly configure the energy saving policy of the UE to the UE through the NAS message, which may be referred to as the second embodiment. Or, the terminal management module may also send the energy-saving policy of the UE to the RAN, and the RAN configures the energy-saving policy to the UE. Regarding the energy saving policy of the AMF, that is, the AM energy saving policy, the terminal management module may send the energy saving policy of the AMF to the PCF through the UDR, and the PCF sends the energy saving policy of the AMF to the AMF, as shown in the second embodiment. Alternatively, the terminal management mode may also directly configure the energy saving policy of the AMF to the AMF, as shown in the first embodiment. Regarding the energy saving policy of the RAN, that is, the AN energy saving policy, the terminal management module may also send the energy saving policy of the RAN to the PCF through the UDR, and the PCF sends the energy saving policy of the RAN to the RAN through the AMF, as shown in the second embodiment. Or, the terminal management module may also send the energy saving policy of the RAN to the AMF, and the AMF configures the energy saving policy to the RAN.
