Description

Technical Field

[0001] This application relates to the field of wireless communication technologies, and in particular, to a method, apparatus, terminal device, and system for negotiating an extended discontinuous reception function. Background Art

[0002] With the continuous empowerment of vertical industries by 5G (5th Generation Mobile Communication Technology), the characteristics of 5G such as large bandwidth, high reliability, and low latency, and advantages such as supporting slicing, service-based architecture, separation of control and media, and MEC (Mobile Edge Computing) provide new opportunities for the development of 5G Internet of Things. 3GPP (3rd Generation Partnership Project) defines the eDRX (extended discontinuous reception) function in the 5G standard.

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

[0004] In the current eDRX process, both the terminal and the network support the eDRX function, and negotiate whether to enable it and the eDRX period when the terminal registers with the network. After successful negotiation, the terminal can not monitor paging for a long time. However, due to the activation of the eDRX function, the terminal cannot receive incoming calls for voice services, affecting the usage experience of voice services, such as smart watches. Currently, the Internet of Things terminal design solutions fail to effectively reconcile the contradiction between the eDRX low-power mode and the real-time requirements of voice services, and lack a special solution for this composite scenario.

[0042] In order to make the objectives, technical solutions and advantages of this application more clear and understandable, the following further elaborates on this application in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely used to explain this application and are not intended to limit this application.

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

[0044] eDRX (Extended Discontinuous Reception): A power-saving mode defined by 3GPP. In each eDRX cycle, the terminal can only listen for paging and receive downlink data within the set paging time window, and the terminal is in a dormant state for the rest of the time, neither listening nor receiving data.

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

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

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

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

[0049] UPF (User Plane Function): An important part of the 5G core network, mainly responsible for functions related to the routing and forwarding of 5G core network user plane data packets.

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

[0051] PCF (Policy Control function): An important part of the 5G core network, responsible for formulating network resource allocation policies, user permission management, and service quality (QoS) guarantee rules.

[0052] The method for negotiating the extended discontinuous reception function provided by the embodiments of the present application can be applied to, for example, Figure 1 the application environment shown. Among them, the user equipment 102 accesses the network through the base station and interacts with the AMF network element 104. In response to the request of the user equipment 102, the AMF network element 104 interacts with other network elements in the network to implement access control and mobility management. Among them, the user equipment 102 can be, but is not limited to, various personal computers, laptop computers, smart phones, tablet computers, Internet of Things devices, and portable wearable devices. The Internet of Things devices can be smart speakers, smart TVs, smart air conditioners, smart in-vehicle devices, projection devices, etc. The portable wearable devices can be smart watches, smart bracelets, head-mounted devices, etc. The head-mounted device can be a virtual reality (VR) device, an augmented reality (AR) device, smart glasses, etc.

[0053] In an exemplary embodiment, as Figure 2 shown, a method for negotiating the extended discontinuous reception function is provided. Taking the AMF network element 104 in Figure 1 as an example, it includes:

[0054] Step 202, when it is detected that the establishment of the voice PDU session of the user equipment is successful, determine whether there are extended discontinuous reception parameters in the context of the user equipment.

[0055] Among them, the PDU session (Protocol Data Unit Session) refers to the process of communication between the user terminal (UE) and the data network (DN) in the 5G network. After the PDU session is established, a data transmission channel will be formed. When the user equipment needs to perform a voice service, it needs to first establish a voice PDU session with DNN=IMS to establish a logical connection between the user equipment and the IP multimedia subsystem data network. Among them, DNN refers to the data network name, and IMS is an IP-based multimedia subsystem. When the AMF network element interacts with the SMF network element and determines that the establishment of the voice PDU session is successful, it determines whether there are extended discontinuous reception parameters in the UE context. The UE context refers to the set of relevant information and status of the user equipment in the network. The extended discontinuous reception parameters refer to Extended idle mode DRX Parameters, including eDRX Parameters and PTW Parameters (paging time window parameters). The eDRX Parameters are, for example, the eDRX period, and the PTW Parameters are, for example, 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 the on / off state of the extended discontinuous reception function of the user equipment.

[0057] Step 204, if the extended discontinuous reception parameter exists in the context of the user equipment, notify the user equipment to turn off 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 enabled 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 the RAN, and maintains the reachable state of the called party.

[0059] In the above method for negotiating the extended discontinuous reception function, when it is detected that the establishment of the voice PDU session of the user equipment is successful, it is judged whether the extended discontinuous reception parameter exists in the context of the user equipment; if the extended discontinuous reception parameter exists in the context of the user equipment, notify the user equipment to turn off the extended discontinuous reception function. In this way, 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 established successfully, enabling the terminal supporting eDRX to perform voice services normally, effectively reconciling the contradiction between the eDRX low-power mode and the real-time requirements of voice services, and improving the usage experience of voice services.

[0060] In an exemplary embodiment, the method further includes: retaining the extended discontinuous reception parameter in the context of the user equipment.

[0061] Among them, the original extended discontinuous reception parameter of the user equipment is retained in the UE context for use when enabling the eDRX function of the user equipment subsequently.

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

[0063] Among them, when the UE requests to release the voice PDU session with DNN = IMS, the AMF network element judges whether the extended discontinuous reception parameter is retained in the UE context, and sends the retained extended discontinuous reception parameter 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 release is successful, the network notifies the terminal to enable the eDRX function, so that the terminal can use the eDRX function to save power when there is no voice service, effectively reconciling the contradiction between the eDRX low-power mode and the real-time requirements of voice services.

[0065] In an alternative implementation, referring to Figure 3 , the steps for establishing a PDU session include: 1. The UE sends a request to establish a voice PDU to the network: 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 a response message for creating a 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 transfers key information during the PDU session establishment process and transfers a 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 parameter in the UE context. If there is an eDRX parameter, it sends an N2 PDU session request to the RAN, resets the eDRX parameter to "0", and saves the original eDRX parameter: 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 eDRX function of the UE: AN-specific resource setup (PDU Session Est. Accept, eDRX = 0);

[0074] 10. The RAN feeds back a 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 Session Modification.

[0077] In an alternative implementation, referring to Figure 4 , the steps to release the PDU session include: 1. The UE sends a request to the network to release the voice PDU: 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 response message for releasing the PDU session to the AMF network element: Nsmf_PDUSession_CreateSMContext Response;

[0081] 5. The AMF network element processes according to the original eDRX parameters reserved in the UE context, sends a request response message to the RAN, requests the RAN to release the N2 resources related to the PDU session, and enables the original eDRX parameters: N2 Resource release Request (PDU Session Release, eDRX = original value);

[0082] 6. The RAN interacts with the UE to modify relevant resources, enabling the UE to activate the eDRX function: AN-specific resource modification (PDU Session Release Command, eDRX);

[0083] 7. The RAN feeds 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 terminate the association of the session management policy: SM policyAssociation Termination;

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

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

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

[0089] Exemplarily, the video surveillance terminal is configured with eDRX function and voice call function, and both have been subscribed in the UDM. The UE powers on and registers to the 5GC (5G Core Network). The registration request carries the eDRX parameters. The AMF issues the eDRX parameters in the registration response message according to the subscribed information of eDRX to enable the eDRX function of the UE. To save power, the video surveillance terminal only establishes a data PDU session channel for video stream transmission under normal circumstances and is in the eDRX state during dormancy. In case of emergency, the voice button is pressed manually to trigger the establishment of a voice PDU session. When the session is successfully established, the network notifies to turn off the eDRX function, and then the voice service is used normally to keep the reachable state for incoming calls. When the voice usage is finished, the voice function is ended manually to trigger the release of the voice PDU session. When the session release is successful, the eDRX parameters sent by the network are received, and the eDRX negotiated during registration is re-enabled.

[0090] In an exemplary embodiment, as Figure 5 shown, a method for negotiating the extended discontinuous reception function is provided. Taking the user equipment 102 in Figure 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 are extended discontinuous reception parameters in the context of the user equipment. If there are extended discontinuous reception parameters in the context of the user equipment, send a notification message to the user equipment.

[0092] Step 504, based on the notification message, turn off the extended discontinuous reception function.

[0093] Among them, when the user equipment needs to perform a voice service, it is necessary to first establish a voice PDU session with DNN = IMS to establish a logical connection between the user equipment and the IP multimedia subsystem data network. Here, DNN refers to the data network name, 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 are extended discontinuous reception parameters in the UE context. If there are extended discontinuous reception parameters in the context of the user equipment, it indicates that the user equipment has enabled the discontinuous reception function. The AMF network element notifies the user equipment to turn off or cancel the extended discontinuous reception function in the messages returned to the UE and the RAN to keep the reachable state for incoming calls.

[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 while the session is successfully established, enabling the terminal supporting eDRX to perform voice services normally, effectively reconciling the contradiction between the eDRX low-power mode and the real-time requirements of voice services, and improving the usage experience of voice services.

[0095] In an exemplary embodiment, the method further includes: sending a voice PDU session release request to an 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 extended discontinuous reception parameters to the user equipment during the process of releasing the voice PDU session; and enabling the extended discontinuous reception function based on the extended discontinuous reception parameters.

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

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

[0098] In an exemplary embodiment, the method further 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 extended discontinuous reception parameters; according to the user subscription data, sending a registration response message including the extended discontinuous reception parameters to the user equipment, and saving the extended discontinuous reception parameters in the context of the user equipment; and enabling the extended discontinuous reception function based on the extended discontinuous reception parameters.

[0099] Among them, the UE carries extended idle mode DRX parameters in the Registration Request message. The AMF network element processes the UE's registration request message, obtains the AM subscription data from the UDM network element, determines whether it includes extended discontinuous reception parameters, that is, eDRX Parameters and PTW Parameters, and notifies the UE of the extended discontinuous reception parameters to be used in the Registration Accept message according to the UE's subscription data or local configuration. At the same time, the AMF network element saves the negotiated extended discontinuous reception parameters in the context of this UE. The AMF network element will perform paging processing according to the relevant eDRX parameters subsequently, without judging what kind of service the UE is currently performing.

[0100] It should be understood that although the steps in the flowcharts involved in the above-described embodiments are shown sequentially according to the arrows, these steps are not necessarily executed sequentially in the order indicated by the arrows. Unless there is a clear indication in this article, the execution of these steps has no strict order limit, and these steps can be executed in other orders. Moreover, at least some of the steps in the flowcharts involved in the above-described embodiments may include multiple steps or multiple stages. These steps or stages are not necessarily executed at the same time, but can be executed at different times. The execution order of these steps or stages is not necessarily sequential, but can be executed alternately or alternately with at least some of the steps or stages in other steps or other steps.

In the above manner, once the terminal requests to establish a voice PDU session, the network notifies the terminal to turn off the eDRX function while the session is successfully established, enabling the terminal supporting eDRX to perform voice services normally, effectively reconciling the contradiction between the eDRX low-power mode and the real-time requirements of voice services, and improving the usage experience of voice services.
