Referring to fig. 2, fig. 2 is a flowchart of a direct communication initiation control method provided in an embodiment of the present application, where the method is applied to a network device, and as shown in fig. 2, the method includes the following steps:

step 201, sending a notification message, where the notification message is used to notify a target terminal to start the direct communication, and the target terminal includes at least one first terminal.

In an embodiment of the present application, the notification message may include at least one of the following: Non-Access Stratum (NAS) messages, Radio Resource Control (RRC) messages, and paging messages.

Optionally, for the first terminal in the connected state, the direct communication may be started through NAS information or RRC message notification, or may also be started through paging message notification; for a first terminal in the disconnected state, the direct communication may be initiated through a paging message notification.

For example, in an embodiment, the AMF may notify the first terminal in the connected state of initiating the direct communication through the NAS information, and may also notify the first terminal in the unconnected state of initiating the direct communication through a paging message. In another embodiment, the RAN may notify the first terminal in the connected state to initiate the direct communication through an RRC notification message, and may also notify the first terminal in the unconnected state to initiate the direct communication through a paging message. The unconnected state may be understood as being in an idle and suspended state or an inactive state.

The target terminal is a designated first terminal that determines to send the notification according to a certain rule, and the target terminal that determines to send the notification may include one or more first terminals, which is not further limited herein.

Optionally, in an embodiment, when the notification message is a paging message, the paging message carries a reason value (paging cause) for starting a direct communication indication, where the reason value for starting the direct communication indication is used to indicate that the first terminal starts direct communication after monitoring the paging message.

In this embodiment, the first terminal may analyze the obtained cause value after receiving the paging message, and when the cause value carried in the paging message is used to indicate that the first terminal starts direct communication after monitoring the paging message, the first terminal may control to start direct communication based on the cause value.

Optionally, before sending the notification message, the method further includes:

and receiving a request message of the second terminal or the application server, wherein the request message is used for requesting the network equipment to inform the target terminal to start direct communication.

In this embodiment of the application, the receiving request message may be sent by the second terminal, or may be sent by the application server. The first terminal may be understood as a PUE or other UE with the same function. The second terminal may be understood as any type of UE, for example, PUE or VUE, etc., which are not further limited herein.

It should be appreciated that in one embodiment, the second terminal may send the request message directly to the network device. For example, the second terminal may send the request message to an Access and Mobility Management Function (AMF), or may send the request message to a Radio Access Network (RAN).

In another embodiment, the second terminal may send a request message to the application server, which forwards the request message. The Application server may be understood as an Application Function (AF). For example, in this embodiment, the request message may be sent to the AF through an application layer message. The AF sends a service request to a Policy Control Function entity (PCF) through a Network Exposure Function (NEF), where the request is used to request a core Network to trigger a specific service to start the PC5 interface communication.

In yet another embodiment, the request message may also be sent to the network device autonomously by the application server.

It should be noted that the target terminal may be determined by the network device, or may be provided by the second terminal and the application server, which is not further limited herein.

Optionally, the request message includes at least one of the following:

a service type (service type);

an application identifier;

a communication type of the direct communication;

a first identity of the first terminal.

When the direct communication is PC5 communication, the communication type of the direct communication may be understood as a PC5 interface communication type, and may be, for example, a communication type such as broadcast, unicast, or multicast. The first Identifier may be at least one of an application layer Identifier, a Subscription encrypted Identifier (SUCI), and a Globally Unique Temporary UE Identity (GUTI).

Optionally, in an embodiment, the target terminal includes at least one of:

a first terminal mapped by a first identifier in the request message;

a first terminal determined based on a location of the second terminal.

In this embodiment of the application, when the first identifier exists in the request message, it may indicate that the first terminal mapped corresponding to the first identifier is a first terminal that the second terminal or the application server desires to establish direct communication. At this time, the network device may directly determine the first terminal mapped by the first identifier as the target terminal. In the absence of the first identity in the request message, the network device may determine the target terminal based on the location of the second terminal, this time for the first terminal for which the network device desires to establish direct communication. In addition, the target terminal can be determined by combining the first terminal which the second terminal or the application server desires to establish the direct communication and the first terminal which the network equipment desires to establish the direct communication. The specific combination mode may be set according to actual needs, for example, may be an intersection or a union.

In this embodiment, the adjacent terminal is determined based on the position of the second terminal, and then the first terminal is determined based on the context and the subscription information. For example, the network device may be based on the proximity of the second terminal to the target terminal for the context and subscription information of the first terminal.

Optionally, the sending the notification message includes:

and sending the notification message in the target area.

Wherein the target area may be determined according to any one of:

the location of the second terminal;

a notification scope provided by the application server;

a tracking area of the first terminal;

In the embodiment of the present application, the target area may be determined based on any one or more of the above. The following will be described in detail by taking the example of the notification range provided according to the location of the second terminal and/or the application server.

For example, in an embodiment, the area where the second terminal is located may be determined based on the location of the second terminal, and the target area may be determined based on the area. Or determining information of the nearby first terminal based on the position of the second terminal, and determining which first terminals need to be notified to start direct communication based on the information of the nearby first terminal and subscription information of the second terminal or the context of the second terminal, thereby determining the target area. It should be understood that, in the present embodiment, in the case where the request message is transmitted by the second terminal, the target area may be determined based on the position of the second terminal.

In another embodiment, the target area may also be determined based on a notification area provided by the server. It should be understood that the notification area provided by the application server is a notification area in which the application server needs to notify the network side to start direct communication, and the network device maps the area provided by the application server to the area identified by the network device. It should be understood that, when the application server provides the notification area, the notification area may be provided in the request message, or may be provided in another message, which is not further limited herein.

Furthermore, the target area can be determined by combining the position of the second terminal and the notification area provided by the application server. For example, a first area determined for a notification area provided by the application server and a target area selected according to a certain rule based on a second area determined based on the location of the second terminal. The rule may be a union or an intersection, etc., and is not further limited herein.

Optionally, after the sending the notification message, the method further includes:

and receiving a first response message sent by the first terminal, wherein the first response message is used for indicating that the first terminal has started the direct communication.

In this embodiment, after the first terminal receives the paging message, the direct communication may be started, and after the direct communication is started, a first response message is replied to the network device to confirm the first terminal and start the direct communication. In an embodiment, the first response message carries a first identifier of the first terminal, and the second identifier includes at least one of an application layer identifier, a subscription encryption identifier, and a globally unique temporary terminal identifier.

Further, in an embodiment, in a case that the reception request message is sent by a second terminal, after receiving a first response message sent by the first terminal, the method further includes:

sending a second response message to the second terminal;

the second response message carries the second identifier, the second terminal is a terminal that sends a request message, and the request message is used for requesting a network device to notify the target terminal of starting direct communication.

In the embodiment of the application, the network device notifies the first identifier of the first terminal through the second response message, so that the second terminal can know that the direct communication is established with the specific first terminal, and the reliability of data transmission is improved.

It should be noted that, after receiving the paging message, the first terminal may change the current DRX mode.

Optionally, changing the current DRX mode comprises any one of:

mode 1, under the condition that the current time is in the dormant state of the current DRX mode, the dormant state is adjusted to an active state;

mode 2, when the current DRX mode is the first DRX mode, the current DRX mode is changed into the second DRX mode.

For the above mode 1, the sleep state may be understood as an Off state, and the active state may be understood as an On state, assuming that the DRX mode is in an Off state at this time, and Off is turned On for a certain period of time.

With respect to the above mode 2, the above-mentioned first DRX mode may be understood as a DRX mode that always keeps silent, and the above-mentioned second DRX mode may be understood as a DRX mode that has a certain period of the switch PC5 interface to listen and transmit. In an embodiment, the second DRX mode may be a DRX mode mapped by a traffic type or an application identity or a temporary group identity.

In this embodiment, the DRX mode may be referred to as DRX pattern, or may be referred to as DRX Cycle. Alternatively, different DRX modes may be understood as DRX with different periods, wherein a first DRX mode is changed to a second DRX mode, which may be understood as changing from one DRX to another DRX, wherein the period of the DRX before the change is different from the changed DRX period.

It should be understood that changing the current DRX mode refers to handling DRX for direct communication, and in the embodiment of the present application, the direct communication may be PC5 interface communication or sidelink communication.
