Evolution, the embodiments of the present application are also applicable to similar technical problems.

ProSe service (ProSe service)

The technical solutions provided by the embodiments of the present application are applicable to proximity-based services (Proximity-based services, ProSe) services. In the ProSe service, a communication link can be directly established between two adjacent terminal devices without establishing a communication link based on an access network device. Based on this, two terminal devices can transmit data without using an access network device. . In some embodiments, the ProSe service may also be called a proximity service, or a proximity service service.

ProSe services can be applied to a variety of scenarios, for example, applicable to but not limited to the following scenarios (or fields): vehicle to everything (V2X), social applications (for example, online sharing of files or materials at company meetings, sharing with friends at gatherings) videos or photos, etc.), local services (for example, a shopping mall provides advertising information services for nearby users, such as finding restaurants and coffee shops near the shopping mall), or network relay (for example, when a terminal device has a poor cellular signal , the terminal device can communicate with other terminal devices through device-to-device (device to device, D2D) communication, so as to communicate with the access network device and the cellular network), etc.

ProSe services may include multiple types, for example, ProSe discovery services, ProSe communication services, ProSe positioning services, and so on. The terminal equipment can realize or complete various ProSe services through the operation of different ProSe services. As an example, the terminal device can complete the ProSe discovery service through ProSe discovery-related operations, for example, to find a suitable target terminal device by monitoring announcement messages of other terminal devices at close range. As another example, the terminal device may perform ProSe communication services through operations related to ProSe communication, for example, establish a short-distance connection between terminal devices through a PC5 wireless interface to perform ProSe communication. As yet another example, the terminal device may complete the ProSe positioning service through operations related to ProSe positioning, such as measuring or determining information such as relative positions, relative angles, and relative distances between terminal devices.

Specifically, the ProSe discovery service may refer to that a terminal device capable of ProSe service discovers other terminal devices adjacent to itself through a short-distance discovery operation. As an example, a terminal device may discover other terminal devices adjacent to itself based on a D2D discovery parameter. After the ProSe discovery process, the terminal device can select a suitable target terminal device or a terminal device using the target service or target application, and then establish a short-distance communication link with it for ProSe communication.

There are two discovery modes in ProSe discovery, namely direct discovery mode A and direct discovery mode B. FIG. 2 is an example diagram of a direct discovery mode A provided by the embodiment of the present application. As shown in Figure 2, in the direct discovery mode A, the terminal equipment of the ProSe service may include announcing terminal equipment (announcing UE) and monitoring terminal equipment (monitoring UE). Exemplarily, in the case of direct discovery mode A, the process of ProSe discovery can be described as:

The announcing terminal device may broadcast an announcement message, for example, broadcast the D2D discovery parameter through the announcement message. In some embodiments, the D2D discovery parameter may include service information or application information of the announced terminal device. In some embodiments, the D2D discovery parameter may also include the identity of the announced terminal device. As a specific example, the D2D discovery parameters broadcast by the announcing terminal device may include application information of the announcing terminal device and an identifier of the announcing terminal device.

The monitoring terminal device can receive the announcement message broadcast by the announcing terminal device. If it monitors the announcement message it is interested in, the monitoring terminal device can obtain the information of the announcing terminal device according to the monitored announcement message, and may establish a short distance with the announcing terminal device. connect.

FIG. 3 is an example diagram of a direct discovery mode B provided by the embodiment of the present application. As shown in FIG. 3, in the direct discovery mode B, the terminal equipment of the ProSe service may include a discovering terminal equipment (discoverer UE) and a discovered terminal equipment (discoveree UE). Exemplarily, in the case of direct discovery mode B, the process of ProSe discovery can be described as:

The discovery terminal device may broadcast a discovery request message, and find a target terminal device or a terminal device using a target service or a target application through the discovery request message. In some embodiments, the discovery request message may include an identifier of a target terminal device, information of a target service or a target application, and the like. In some embodiments, the discovery request message may also include the identifier of the discovery terminal device.

The discovered terminal device can receive the discovery request message of the discovered terminal device, and compare it with the discovery matching parameters provided by the network side to determine whether it is the target terminal device to be found, or use the target service or target application Terminal Equipment. If the discovered terminal device can match the message after receiving the discovery request message, the discovered terminal device can respond to the discovery terminal device. Exemplarily, in the example of FIG. 3 , the discovered terminal device #2 and the discovered terminal device #3 may match the discovery request message of the discovered terminal device #1, and based on this, send a response message to the discovered terminal device #1.

In some embodiments, the wireless communication system supporting the ProSe service may further include a direct discovery name management function (direct discovery name management function, DDNMF) network element. The DDNMF network element may be responsible for assigning a corresponding ProSe code (or short distance code) to the terminal device after receiving a discovery request from the terminal device, such as relay service code/mask (relay service code/filter) information. Announcing terminal devices and monitoring terminal devices, or discovering terminal devices and discovered terminal devices, can send request messages to DDNMF network elements before performing ProSe discovery, so as to request DDNMF network elements to allocate corresponding ProSe codes, such as target service or target application Mask information, etc.

The embodiment of the present application does not specifically limit the deployment mode of the DDNMF network element. As a logical network element, in some embodiments, the DDNMF network element can be deployed independently in the core network; in other embodiments, the DDNMF network element can also be integrated into other network elements during deployment. In addition, the embodiment of the present application does not specifically limit the deployment location of the DDNMF network element. For example, the DDNMF network element can be deployed on the control plane of the core network, or can be deployed on the user plane.

The ProSe communication service may refer to that a terminal device may establish a direct communication connection between terminal devices through ProSe communication after discovering other terminal devices adjacent to itself. FIG. 4 is an example diagram of ProSe communication between terminal devices provided in an embodiment of the present application. As shown in Figure 4, a terminal device with ProSe communication capabilities can establish a direct connection with another terminal device with ProSe communication capabilities for direct communication. As an implementation, a communication connection can be established through a PC5 wireless interface, for example, through a PC5 The wireless interface forms a PC5 communication link (eg, PC5 unicast link).

In some embodiments, ProSe communications may reuse resources of the mobile cellular network. For example, a terminal device performing ProSe communication can obtain frequency resources required for ProSe communication under the control of an access network device in a cellular network, thereby establishing a ProSe communication link, and perform ProSe direct communication based on the communication link, while Communication through access network equipment is not required.

The ProSe positioning service may refer to a terminal device using ProSe positioning technology to realize positioning between short-distance terminal devices, for example, measuring or determining information such as relative distance, relative position, and relative angle between terminal devices.

In related technologies, in order to support ProSe services between terminal devices, terminal devices need to continuously perform related ProSe service operations, such as continuously broadcasting ProSe discovery messages or ProSe communication messages, and continuously performing ProSe discovery messages of other nearby terminal devices. Listening, or continuously performing ProSe positioning measurement (such as distance measurement, angle measurement, position measurement, etc.) or determination operations on other nearby terminal devices, resulting in a large consumption of terminal device resources (such as computing power, power, etc.).

In order to solve the above problems, embodiments of the present application provide a communication method and a communication device, so as to reduce resource consumption of terminal devices. Embodiments of the present application will be described in detail below in conjunction with the accompanying drawings.

FIG. 5 is a schematic flowchart of a communication method provided by an embodiment of the present application. The method shown in FIG. 5 is executed by the first terminal. The first terminal is a terminal device with ProSe service capability (in some embodiments, it can also be called a terminal device with ProSe communication capability), for example, the first terminal can perform ProSe discovery, ProSe communication, or ProSe positioning For example, the first terminal may be the terminal device shown in Figure 1, or the first terminal may be the announcement terminal device or the monitoring terminal device shown in Figure 2, or the first terminal may be, for example, It is terminal device #1 or terminal device #2 shown in FIG. 4, or, for example, the first terminal may also be a terminal device that initiates a ProSe positioning service request or a terminal device that receives a ProSe positioning service request. The method shown in FIG. 5 may include step S510 and step S520.

In step S510, the first terminal receives first information. The first information is used to instruct the first terminal to execute the operation of the ProSe service between terminal devices corresponding to the first event when the first event is detected.

There may be multiple sources of the first information. In some embodiments, the first information may be information configured by a core network element (such as a PCF network element) for the first terminal. In some embodiments, the first information may be information generated by other devices that interact with the first terminal.

In some embodiments, the first information may include the first event and the operation of the ProSe service corresponding to the first event. In some embodiments, the first information may only include the first event. The content contained in the first message will be introduced in detail later, and will not be repeated here.

The first event may drive the first terminal to perform the operation of the ProSe service corresponding to the first event. The information of the first event may include multiple types. For example, the information of the first event may include at least one of the following information: time information, cycle information, location information of the first terminal, and movement information of the first terminal, etc. . It should be noted that the information of the first event listed above is only an exemplary list, and this embodiment of the present application is not limited thereto, and may also include other information.

Specifically, when the information of the first event includes time information, the first information may be used to indicate that the first terminal executes a corresponding ProSe service operation when the time indicated by the first event arrives. For example, if the information of the first event is 10 am every day, the first event will be triggered at 10 am every day, and the first terminal will execute the operation of the ProSe service corresponding to the first event at 10 am every day.

When the information of the first event includes period information, the first information may be used to instruct the first terminal to perform corresponding ProSe service operations at specific period intervals. For example, the information of the first event may be every 20 minutes, then the first event will be triggered every 20 minutes, and the first terminal may perform the operation of the ProSe service corresponding to the first event every 20 minutes.

When the information of the first event includes the location information of the first terminal, the first information may be used to indicate that the first terminal performs a corresponding ProSe service operation when it arrives at the location. For example, the information of the first event may be a specific cell identifier, and after the first terminal arrives at the specific cell, the first terminal executes the operation of the ProSe service corresponding to the first event. The present application does not specifically limit the type of location information of the first terminal. Exemplarily, the location information may be, for example, a specific cell identifier, tracking area identifier, or latitude and longitude information.

When the information of the first event includes the movement information of the first terminal, the first information may be used to indicate that the corresponding ProSe service operation is executed when the movement information of the first terminal satisfies a specific condition. For example, the information of the first event may be that the first terminal enters a certain area or leaves a certain area, then when the first terminal arrives at the area or leaves the area, the first terminal performs the operation of the ProSe service corresponding to the first event or, the information of the first event may be the distance between the first terminal and a specific location or a specific area, as an example, when the information of the first event is the distance between the first terminal and a specific area (such as the distance between the two is 10 meters), if the distance between the first terminal and the specific area satisfies the condition, the first terminal executes the operation of the ProSe service corresponding to the first event. It should be understood that the aforementioned area may refer to, for example, a cell list, a tracking area list, or an area range formed by latitude and longitude information. It should be noted that the mobile information of the first terminal may include other information besides the ones listed above, which is not specifically limited in this embodiment of the present application.

In some embodiments, the information of the first event may only include one type, for example, only time information, or only period information, and the like. In some other embodiments, the information of the first event may include multiple types, for example, it may include time information and period information at the same time, or it may include time information and the location information of the first terminal at the same time. There are other combinations, for example, including time information, period information, and location information of the first terminal at the same time, which will not be listed here.

The operation of the ProSe service may refer to the operation performed when the first terminal performs the ProSe service. Optionally, the operations of the ProSe service may include various types, which are not limited in this embodiment of the present application. Exemplarily, the operations of the ProSe service may include at least one of the following operations: ProSe discovery, ProSe communication, and ProSe positioning .

In some embodiments, the aforementioned operations of the ProSe service may further include more specific operations. As an example, when the operation of the ProSe service is ProSe discovery, it may further refer to the ProSe discovery in the direct discovery mode A, or the ProSe discovery in the direct discovery mode B. Or further, it may refer to performing the discovery message announcement operation of the direct discovery mode A, or may refer to the execution of the discovery message monitoring operation of the direct discovery mode A, or may also refer to the operation of discovering terminal devices in the direct discovery mode B , or may refer to the operation of the discovered terminal device performing the direct discovery mode B, and the like. As another example, when the operation of the ProSe service is ProSe communication, it may further refer to establishing a ProSe connection between terminal devices. As yet another example, when the operation of the ProSe service is ProSe positioning, it may further refer to measuring or determining information such as relative distances, relative angles, and relative positions between terminal devices.

In step S520, when the first terminal detects that the first event is triggered, it executes the operation of the ProSe service.

As an example, when the first information is used to indicate that the ProSe discovery operation is performed at 10 am every day, when the first terminal detects that the current time is 10 am, the ProSe discovery operation is automatically performed. As another example, when the first information is used to indicate that the first terminal reads the cell identity of cell A from the system information of the access network equipment, the ProSe communication operation is performed, then when the first terminal reads the When the specific cell is identified, the ProSe communication operation will be automatically performed.

The embodiment of the present application introduces an event triggering mechanism. By providing the first event to the first terminal, the first terminal only executes the operation of the ProSe service corresponding to the first event when the first event is triggered, so as to prevent the first terminal from continuously The operation of the related ProSe service can further reduce resource consumption of the first terminal.

As mentioned above, the source of the first information may include various sources, for example, it may be configured by the network element of the core network to the first terminal, or it may be generated and sent to first terminal. The source of the first information will be introduced in detail below in conjunction with Embodiment 1 and Embodiment 2 respectively.

Embodiment one:

In this embodiment, the first information is a policy configured by a network element of the core network to the first terminal. A network element of the core network may configure first information for a terminal device (for example, a first terminal). In this embodiment, the first information may also be called a first policy, and the policy refers to a policy related to the operation of a ProSe service. In some embodiments, the network element of the core network may be a PCF network element, for example.

FIG. 6 is a schematic flowchart of a communication method provided by another embodiment of the present application. As shown in FIG. 6, in step S610, the PCF network element configures the first information to the first terminal. The first information is used to instruct the first terminal to execute the operation of the ProSe service corresponding to the first event when the first event is detected.

In step S620, when the first terminal detects that the first event is triggered, it executes the operation of the ProSe service.

The embodiment of the present application does not limit the specific manner in which the PCF network element configures the first information to the first terminal, for example, reference may be made to the configuration manner in existing standards. An example in which the PCF network element configures the first information to the first terminal is given below with reference to FIG. 7 .

Referring to FIG. 7 , the manner in which the PCF network element configures the first information to the first terminal may include steps S710 to S740.

In step S710, the PCF network element starts the update process of the first terminal policy rule. It should be noted that, in this embodiment, the first information is borne in the policy rule.

In step S720, the PCF network element invokes the service provided by the AMF network element. As an example, the PCF network element may invoke the Namf_Communication_N1N2MessageTransfer service provided by the AMF network element.

In step S730, the AMF network element sends the updated content of the policy rule of the first terminal received from the PCF network element to the first terminal. In some embodiments, the AMF network element may send the first terminal policy rule to the first terminal in a transparent transmission manner.

In step S740, the first terminal returns an update result response to the AMF network element. At this point, the update of the policy rules of the first terminal is completed, that is, the configuration (or configuration update) of the first information is completed.

In some embodiments, if the first terminal is in the connected state, after the PCF network element invokes the service provided by the AMF network element, the AMF network element may directly forward the updated content of the policy rule of the first terminal to the first terminal. In some embodiments, if the first terminal is in an unconnected state, the method may further include step S725. In step S725, the AMF network element at the network side triggers a service request and starts a paging process.

In some embodiments, after step S740 is executed, the AMF network element can also forward the response message of the update result returned by the first terminal to the PCF network element. As an implementation, the AMF can call the Namf_Communication_N1MessageNotify service to send the first terminal The response message is forwarded to the PCF network element, for details, refer to step S750 in the flow chart shown in FIG. 7 .

In some embodiments, the first information configured by the PCF network element to the first terminal is public policy information. The first information may include the first event and the operation of the ProSe service corresponding to the first event. As an example, the first information may be that a ProSe discovery operation is performed at 10 am every day. Wherein, the first event is at 10 am every day, and the operation of the ProSe service corresponding to this event is the operation of ProSe discovery. Then, at 10 am every day, the first terminal starts to perform the ProSe discovery operation due to the trigger of the first event.

In some embodiments, the first information configured by the PCF network element to the first terminal is dedicated policy information. The first information may only include the first event, because when the first information is dedicated policy information, the first information itself can already represent the operation of the ProSe service, and there is no need to carry information about the first event in the first information. Information about the operation of the ProSe service corresponding to the event.

In some embodiments, when the first information is dedicated policy information, if the first terminal is required to perform further ProSe service operations, the first information may further include further ProSe service operations corresponding to the first event. For example, the first information may also include the ProSe discovery operation of the direct discovery mode A corresponding to the first event, or the ProSe discovery operation of the direct discovery mode B corresponding to the first event, then the first terminal may detect When the first event is triggered, the ProSe discovery operation of the direct discovery mode A or the ProSe discovery operation of the direct discovery mode B are correspondingly performed.

As an example, when the first information is policy information for ProSe discovery, the first information may only include the first event, and the first event is used to trigger ProSe discovery. For example, the first information may be at 10 am every day, then the first terminal starts to perform the ProSe discovery operation at 10 am every day due to the trigger of the first event; or, the first information may be location information (such as specific cell identifier, tracking area identifier, etc.), then the first terminal starts to perform the ProSe discovery operation when it arrives at the location. In some embodiments, when the first information is policy information discovered by ProSe, the first information may include the first event and further ProSe discovery-related operations corresponding to the first event, for example, the first information is every day at 10 am point, execute the ProSe discovery in the direct discovery mode A, wherein the first event is at 10 am every day, and the further ProSe discovery operation corresponding to this event is the ProSe discovery in the direct discovery mode A. Then, at 10 am every day, the first terminal starts to perform the ProSe discovery operation of the direct discovery mode A due to the trigger of the first event.

As another example, when the first information is policy information for ProSe communication, the first information may only include the first event, and the first event is used to trigger ProSe communication. For example, the first information may be at 10 am every day, and the first terminal starts to perform the ProSe communication operation at 10 am every day due to the trigger of the first event; or, the first information may be location information (such as specific cell identifier, tracking area identifier, etc.), then the first terminal starts to perform the operation of ProSe communication when it arrives at the location.

As yet another example, when the first information is policy information for ProSe positioning, the first information may only include the first event, and the first event is used to trigger ProSe positioning. For example, the first information may be at 10 am every day, and the first terminal starts to perform ProSe positioning at 10 am every day due to the trigger of the first event; or, the first information may be position information (such as specific cell identifier, tracking area identifier, etc.), then the first terminal starts to perform the operation of ProSe positioning when it arrives at the location. In some embodiments, when the first information is policy information for ProSe positioning, the first information may include the first event and further ProSe positioning related operations (such as positioning methods) corresponding to the first event, for example, the first The information is 10 am every day, and the ProSe positioning operation of measuring the relative position between terminal devices is performed, wherein the first event is 10 am every day, and the further ProSe positioning operation corresponding to this event is measuring the relative position between terminal devices. Location. Then, at 10 am every day, the first terminal starts to perform the operation of measuring the relative positions between the terminal devices due to the trigger of the first event. In some embodiments, operations related to ProSe positioning may also include measuring or determining information such as relative distances and relative angles between terminal devices.

The core network element (such as PCF network element) is used to configure the first information to the first terminal, so that the first terminal can receive the corresponding configuration information after starting up, further reducing the resource consumption of the terminal device, and at the same time, the core network element The first information may be updated, so that the configuration of the first information is more flexible.
