Description

Technical Field

[0001] The present application relates to the field of wireless communication technology, and in particular to a method, apparatus, terminal equipment, and system for negotiating and extending a discontinuous reception function. Background Art

[0002] As 5G (fifth generation mobile communication technology) continues to empower vertical industries, its features such as large bandwidth, high reliability, and low latency, along with support for slicing, service-oriented architecture, control-media separation, and mobile edge computing (MEC), are providing new opportunities for the development of the 5G Internet of Things. The 3rd Generation Partnership Project (3GPP) has defined the extended discontinuous reception (eDRX) feature in the 5G standard.

[0003] For IoT terminals such as NB-IOT (narrowband IoT) terminals and RedCap (Reduced Capability, a lightweight 5G IoT technology) terminals, eDRX will extend the reception interval to 10.24 seconds in connected mode; in idle mode, eDRX will extend the paging monitoring and TAU (Tracking Area Update) update interval to more than 40 minutes, thereby achieving a balance between downlink service latency and power consumption, greatly extending the terminal battery life.

[0004] In the current eDRX process, both the terminal and the network support eDRX. During terminal registration, the terminal negotiates with the network whether to enable the eDRX function and the eDRX cycle. After successful negotiation, the terminal can avoid listening for paging for an extended period. However, the activation of eDRX can prevent the terminal from receiving incoming calls for voice services, impacting the voice service experience, such as in smartwatches. Current IoT terminal designs fail to effectively reconcile the conflict between the low power consumption of eDRX and the real-time requirements of voice services, lacking a dedicated solution for this complex scenario.

[0042] In order to make the purpose, technical solutions and advantages of this application more clear, the following further describes this application in detail with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain this application and are not intended to limit this application.

[0043] To facilitate understanding of the embodiments provided in this application, some terms that appear in the specific description are introduced below:

[0044] eDRX (Extended Discontinuous Reception) is a power-saving mode defined by 3GPP. During each eDRX cycle, a terminal can monitor paging and receive downlink data only within the configured paging time window. During the rest of the time, the terminal remains in a dormant state and neither monitors nor receives data.

[0045] UE (User Equipment): refers to user equipment in mobile communication networks, including mobile phones, tablets, modems, sensors, etc.

[0046] AMF (Access Control And Mobility Management Function): is one of the main functional units in the 5G core network.

[0047] RAN (Radio Access Network): Connects individual devices to the rest of the network via radio connections.

[0048] SMF (Session Management Function): is one of the main functional units in the 5G core network.

[0049] UPF (User Plane Function): It is an important component of the 5G core network and is mainly responsible for the routing and forwarding of user plane data packets in the 5G core network.

[0050] UDM (The Unified Data Management) is an important component of the 5G core network, responsible for managing and storing user-related data and subscription information.

[0051] PCF (Policy Control Function): A crucial component of the 5G core network, PCF is responsible for formulating network resource allocation strategies, user rights management, and Quality of Service (QoS) assurance rules.

[0052] The method for negotiating the extension of the discontinuous reception function provided in the embodiment of the present application can be applied to Figure 1 In the application environment shown, user equipment 102 accesses the network through a base station and interacts with an AMF network element 104. In response to requests from user equipment 102, AMF network element 104 interacts with other network elements to implement access control and mobility management. User equipment 102 may be, but is not limited to, various personal computers, laptops, smartphones, tablets, IoT devices, and portable wearable devices. IoT devices may include smart speakers, smart TVs, smart air conditioners, smart car devices, and projectors. Portable wearable devices may include smart watches, smart bracelets, and head-mounted devices. Head-mounted devices may include virtual reality (VR) devices, augmented reality (AR) devices, smart glasses, and the like.

[0053] In an exemplary embodiment, Figure 2 As shown, a method for negotiating an extended discontinuous reception function is provided, and the method is applied to Figure 1 The following is explained using the AMF network element 104 in FIG. 1 as an example:

[0054] Step 202: When it is detected that the voice PDU session of the user equipment is successfully established, it is determined whether an extended discontinuous reception parameter exists in the context of the user equipment.

[0055] A Protocol Data Unit Session (PDU) refers to the communication process between a user terminal (UE) and a data network (DN) in a 5G network. Once a PDU session is established, a data transmission channel is formed. When a UE needs to perform voice services, it must first establish a voice PDU session (DNN=IMS), establishing a logical connection between the UE and the IP Multimedia Subsystem (IPMS) data network. DNN refers to the name of the data network, and IMS is an IP-based multimedia subsystem. After the AMF and SMF network elements interact and confirm that the voice PDU session is successfully established, they determine whether the UE context contains extended discontinuous reception (DDR) parameters. The UE context is a collection of information and status related to the UE in the network. Extended DRX parameters refer to Extended Idle Mode (IDM) DRX Parameters, including eDRX Parameters and PTW Parameters (Paging Time Window Parameters). eDRX Parameters include the eDRX cycle, and PTW Parameters include the PTW window length.

[0056] Optionally, if the extended discontinuous reception parameter does not exist in the context of the user equipment, there is no need to negotiate whether the user equipment switches the on / off state of the extended discontinuous reception function.

[0057] Step 204: If the extended discontinuous reception parameter exists in the context of the user equipment, the user equipment is notified to disable the extended discontinuous reception function.

[0058] Among them, if the extended discontinuous reception parameter exists in the context of the user equipment, it indicates that the user equipment has turned on the discontinuous reception function. The AMF network element notifies the user equipment to turn off or cancel the extended discontinuous reception function in the message returned to the UE and RAN, and keep the called party reachable.

[0059] In the above-mentioned method for negotiating the extended discontinuous reception function, upon detecting that a voice PDU session has been successfully established for a user device, a determination is made as to whether an extended discontinuous reception parameter exists in the user device's context; if the extended discontinuous reception parameter exists in the user device's context, the user device is notified to disable the extended discontinuous reception function. Through this method, once a terminal requests to establish a voice PDU session, the network notifies the terminal to disable the eDRX function upon successful session establishment, allowing terminals that support eDRX to perform voice services normally. This effectively reconciles the conflict between the eDRX low-power mode and the real-time requirements of voice services, thereby improving the user experience of voice services.

[0060] In an exemplary embodiment, the method further comprises: reserving the extended discontinuous reception parameters in the context of the user equipment.

[0061] The original extended discontinuous reception parameters of the user equipment are retained in the UE context so as to be used when the eDRX function of the user equipment is subsequently enabled.

[0062] In an exemplary embodiment, the method further includes: in the process of releasing the voice PDU session, sending a request response message including an extended discontinuous reception parameter to the user equipment to instruct the user equipment to enable an extended discontinuous reception function based on the extended discontinuous reception parameter.

[0063] Among them, when the UE requests to release the voice PDU session of DNN=IMS, the AMF network element determines whether the extended discontinuous reception parameters are retained in the UE context, and sends the extended discontinuous reception parameters retained in the request response message to the user equipment, so that the UE turns on or enables the extended discontinuous reception function and continues to use the eDRX function in the subsequent process.

[0064] In this embodiment, the terminal requests to release the voice PDU session. When the session is released successfully, the network notifies the terminal to enable the eDRX function. This allows the terminal to use the eDRX function to save power when there is no voice service, effectively reconciling the contradiction between the eDRX low power consumption mode and the real-time requirements of the voice service.

[0065] In an optional implementation, referring to Figure 3 The steps of establishing a PDU session include: 1. The UE sends a request to the network to establish a voice PDU: PDU Session Establishment Request (DNN=IMS);

[0066] 2. The AMF network element triggers the SMF network element to create a new PDU session context for the UE: Nsmf_PDUSession_CreateSMContext Request (DNN=IMS);

[0067] 3. The SMF network element retrieves subscription information from the UDM network element: Subscription Retrieval;

[0068] 4. The SMF network element returns the response information of creating the PDU session to the AMF network element: Nsmf_PDUSession_CreateSMContext Response (DNN=IMS);

[0069] 5. The SMF network element requests the PCF network element to establish a session management policy for the PDU session: SM policy AssociationEstablishment;

[0070] 6. The SMF network element sends an N4 session establishment request message to the UPF network element: N4 Session Establishment;

[0071] 7. The SMF network element transmits key information during the PDU session establishment process and transmits the PDU session establishment acceptance message to the AMF network element: Namf_Communication_N1N2MessageTransfer (PDU Session EstablishmentAccept);

[0072] 8. The AMF network element makes a judgment based on the eDRX parameters in the UE context. If the eDRX parameters exist, it sends an N2 PDU session request to the RAN, resets the eDRX parameters to "0", and saves the original eDRX parameters: N2 PDU Session Request (PDU Session Est. Accept, eDRX=0);

[0073] 9. The RAN interacts with the UE to set access network resources and cancel the UE's eDRX function: AN-specific resource setup (PDU Session Est. Accept, eDRX=0);

[0074] 10. RAN feeds back PDU session response to the AMF network element: N2 PDU Session Response;

[0075] 11. The AMF network element notifies the SMG network element of the PDU session status change information: Nsmf_PDUSession_UpdateSMContext;

[0076] 12. The SMF network element interacts with the UPF network element to update the N4 session context of the PDU session: N4 SessionModification.

[0077] In an optional implementation, referring to Figure 4 , the steps of releasing the PDU session include: 1. The UE sends a request to release the voice PDU to the network: PDU Session Release Request (DNN=IMS);

[0078] 2. The AMF network element sends a PDU session release request to the SMF network element related to the PDU session: Nsmf_PDUSession_UpdateSMContext (PDU Session Release Request);

[0079] 3. The SMF network element interacts with the UPF network element to release the N4 session context of the PDU session: N4 Session Release;

[0080] 4. The SMF network element sends a PDU session release response message to the AMF network element: Nsmf_PDUSession_CreateSMContext Response;

[0081] 5. The AMF network element processes the original eDRX parameters retained in the UE context and sends a request response message to the RAN, requesting the RAN to release the N2 resources related to the PDU session and enable the original eDRX parameters: N2 Resourcerelease Requst (PDU Session Release, eDRX = original value);

[0082] 6. The RAN interacts with the UE to modify related resources so that the UE can enable the eDRX function: AN-specific resource modification (PDU Session Release Command, eDRX);

[0083] 7. RAN sends back a resource release confirmation message to the AMF network element: N2 Resource Release Ack;

[0084] 8. The AMF network element notifies the SMF network element of the PDU session status change information: Nsmf_PDUSession_SMContextStatusNotity (Release);

[0085] 9. The SMF network element interacts with the PCF network element to implement the termination of the session management policy association: SM policyAssociation Termination;

[0086] 10. The SMF network element interacts with the UDM network element to deregister the user equipment context information from the network: Nudm_UECM_Deregistration.

[0087] In an exemplary embodiment, the method further includes: obtaining user contract data from a unified data management function network element in response to a registration request message sent by a user device; the user contract data includes an extended discontinuous reception parameter; based on the user contract data, sending a registration response message including the extended discontinuous reception parameter to the user device, and saving the extended discontinuous reception parameter in the context of the user device.

[0088] Among them, the UE carries extended idle mode DRX parameters in the registration request message Registration Request. The AMF network element processes the UE's registration request message, obtains the AM subscription data from the UDM network element, and determines whether it includes extended discontinuous reception parameters, namely eDRX Parameters and PTW Parameters. According to the UE's subscription data or local configuration, the UE is notified of the extended discontinuous reception parameters to be used in the registration response message Registration Accept. At the same time, the AMF network element saves the negotiated extended discontinuous reception parameters in the context of the UE. The AMF network element will subsequently perform paging processing based on the relevant eDRX parameters and will not determine what service the UE is currently performing.

[0089] For example, a video surveillance terminal is configured with eDRX and voice call capabilities, both of which are subscribed to in the UDM. Upon power-up, the UE registers with the 5G Core Network (5G Core Network). The registration request includes eDRX parameters. Based on the eDRX subscription information, the AMF sends the eDRX parameters in the registration response message to enable the UE's eDRX function. To conserve power, the video surveillance terminal normally establishes only a data PDU session channel for video streaming and remains in an eDRX state when in sleep mode. In an emergency, a manual press of the voice button triggers the establishment of a voice PDU session. Upon successful session establishment, the network receives a notification to disable the eDRX function. Voice services can then be used normally, maintaining the called party's reachability. When voice service is complete, the voice function is manually terminated, triggering the release of the voice PDU session. Upon successful session release, the network receives the eDRX parameters and re-enables the eDRX negotiated during registration.

[0090] In an exemplary embodiment, Figure 5 As shown, a method for negotiating an extended discontinuous reception function is provided, and the method is applied to Figure 1 Taking the user equipment 102 in FIG. 1 as an example, the method includes:

[0091] Step 502: Send a voice PDU session establishment request to the access control and mobility management function network element to instruct the access control and mobility management function network element to establish a voice PDU session. When it is detected that the voice PDU session of the user equipment is successfully established, determine whether there is an extended discontinuous reception parameter in the context of the user equipment. If the extended discontinuous reception parameter exists in the context of the user equipment, send a notification message to the user equipment.

[0092] Step 504: disable the extended discontinuous reception function based on the notification message.

[0093] Among them, when the user equipment needs to perform voice services, it is necessary to first establish a voice PDU session of DNN=IMS to establish a logical connection between the user equipment and the IP multimedia subsystem data network, where DNN refers to the name of the data network and IMS is an IP-based multimedia subsystem. When the AMF network element interacts with the SMF network element and determines that the voice PDU session is successfully established, it determines whether there is an extended discontinuous reception parameter in the UE context. If the extended discontinuous reception parameter exists in the context of the user equipment, it indicates that the user equipment has turned on the discontinuous reception function. The AMF network element notifies the user equipment to turn off or cancel the extended discontinuous reception function in the message returned to the UE and RAN to keep the called party reachable.

[0094] In this embodiment, once the terminal requests to establish a voice PDU session, the network notifies the terminal to turn off the eDRX function at the same time as the session is successfully established, so that the terminal that supports eDRX can perform voice services normally, effectively reconciling the contradiction between the eDRX low power consumption mode and the real-time requirements of voice services, and improving the user experience of voice services.

[0095] In an exemplary embodiment, the method also includes: sending a voice PDU session release request to the access control and mobility management function network element to instruct the access control and mobility management function network element to send a request response message including an extended discontinuous reception parameter to the user equipment during the process of releasing the voice PDU session; and turning on the extended discontinuous reception function based on the extended discontinuous reception parameter.

[0096] Among them, when the UE requests to release the voice PDU session of DNN=IMS, the AMF network element determines whether the extended discontinuous reception parameters are retained in the UE context, and sends the extended discontinuous reception parameters retained in the request response message to the user equipment, so that the UE turns on or enables the extended discontinuous reception function and continues to use the eDRX function in the subsequent process.

[0097] In this embodiment, the terminal requests to release the voice PDU session. When the session is released successfully, the network notifies the terminal to enable the eDRX function. This allows the terminal to use the eDRX function to save power when there is no voice service, effectively reconciling the contradiction between the eDRX low power consumption mode and the real-time requirements of the voice service.

[0098] In an exemplary embodiment, the method also includes: sending a registration request message to an access control and mobility management function network element to instruct the access control and mobility management function network element to obtain user subscription data from a unified data management function network element; the user subscription data includes an extended discontinuous reception parameter; according to the user subscription data, sending a registration response message including the extended discontinuous reception parameter to the user device, and saving the extended discontinuous reception parameter in the context of the user device; and enabling the extended discontinuous reception function based on the extended discontinuous reception parameter.

[0099] Among them, the UE carries extended idle mode DRX parameters in the registration request message Registration Request. The AMF network element processes the UE's registration request message, obtains the AM subscription data from the UDM network element, and determines whether it includes extended discontinuous reception parameters, namely eDRX Parameters and PTW Parameters. According to the UE's subscription data or local configuration, the UE is notified of the extended discontinuous reception parameters to be used in the registration response message Registration Accept. At the same time, the AMF network element saves the negotiated extended discontinuous reception parameters in the context of the UE. The AMF network element will subsequently perform paging processing based on the relevant eDRX parameters and will not determine what service the UE is currently performing.

[0100] It should be understood that, although the various steps in the flowcharts involved in the various embodiments described above are displayed in sequence according to the instructions of the arrows, these steps are not necessarily executed in sequence in the order indicated by the arrows.

If the extended discontinuous reception parameter exists in the user device's context, the device is notified to disable the extended discontinuous reception function. Through this method, once a terminal requests to establish a voice PDU session, the network notifies the terminal to disable the eDRX function upon successful session establishment. This allows terminals that support eDRX to perform voice services normally, effectively reconciling the conflict between the eDRX low-power mode and the real-time requirements of voice services, and improving the user experience of voice services.
