Detailed Description

Referring to fig. 1, a UE interacts with a short-range discovery function and sends a radio broadcast signaling and monitors radio broadcast signaling from other terminals, thereby implementing mutual short-range discovery, and the specific process is as follows:

step 101: UE-a sends a Discovery Request (Discovery Request) to a proximity Discovery Function (ProSe Function) (e.g., user plane bearer over wireless air and core network user plane bearer).

Such as: the Discovery Request may carry one or more items of application information, user identifier, mode information, and role information.

The Application information identifies the Application, and the Application information includes identification information (Application ID) used by the 3GPP network to identify the specific Application, and the Application information may further include near Application identification information (ProSe App ID) used by the 3GPP network to route data to the Application server.

The user identifier is information used by the 3GPP network to identify the user, such as: international Mobile Station Identity (IMSI).

The mode information identifies a discovery mode, for example, the mode a (model a) sends a matching report to the short-distance discovery function for the monitoring party; mode b (model b) is that the monitoring party receives the direct communication request broadcast by other terminals, returns a response to the other party, and sends a matching report to the short-range discovery function by the other party.

The role information identifies whether the terminal is a broadcast sender or a broadcast listener.

Step 102: the ProSe Function receives a discovery request of the UE-A, requests authorization to a subscription Server (HSS) of the UE-A according to the user identification, and the HSS judges that the UE-A subscribes a short-range discovery service and returns an indication allowing short-range discovery operation to be executed.

Step 103: the ProSe Function requests authorization from an application Server (App Server), which returns an indication that close-range discovery operations are allowed to be performed.

Step 103 is an optional step.

Step 104: the ProSe Function sends a Discovery Response (Discovery Response) to UE-a.

For example, the Discovery Response message carries the Discovery code information, and the Discovery Response message is sent to the UE-a through a core network user plane bearer and a wireless air interface user plane bearer.

If UE-a is the broadcast sender, the discovery Code information may include an application Code (App Code), and further, the discovery Code information may include a Response Code Filter (Response Code Filter).

If UE-a is a broadcast listener, the discovery Code information may include an application Code Filter (App Code Filter), and further, the discovery Code information may also include a Response Code (Response Code).

Step 105: UE-B also performs the operations of steps 101-104 described above.

In this example, UE-A is assumed to be the broadcast sender, and UE-B is assumed to be the broadcast listener.

Step 106: the UE-a broadcasts a Direct communication request (Direct communication request) message over the air interface.

For example, the Direct Communication Request message is sent, and carries user information and an application code, where the user information includes a connection Layer user identifier (Layer-2ID), and the Layer-2ID is used for sending a message, which is the application Layer user information, to the UE through a wireless air interface by the peer UE.

Step 107: if UE-A and UE-B both use Model B, then UE-B returns Direct Communication Response to UE-A through wireless air interface, such as sending Direct Communication Response, carrying user information and Response code.

Step 107 is an optional step.

Step 108: if the UE-A and the UE-B both adopt Model B, the UE-A sends a matching request, such as a matching Report (Match Report) message, to a short distance discovery Function (ProSe Function) through a user plane bearer of a wireless air interface and a user plane bearer of a core network, wherein the Match Report message carries application information and a response code;

and if the UE-A and the UE-B both adopt the Model A, the UE-B sends a matching request to a short-distance discovery Function (ProSe Function) through the user plane bearing of the wireless air interface and the user plane bearing of the core network, and the matching request carries the application information and the application code.

Referring to fig. 5, an embodiment of the present invention provides a method for processing a near discovery service of a terminal, where an execution subject of the method is a terminal, and the method includes

In some embodiments, the configuration information is configured by the network side or agreed upon by a protocol.

Embodiments of the present invention are described below with reference to fig. 6, 7, 8, and 9.

Referring to fig. 6, a procedure for initiating discovery between terminals according to a first embodiment of the present invention.

Step 601: the mobile network operator specifies an application identity (App ID) for the application server via a Service Level Agent (SLA), which may be unique within the mobile network (e.g. in digital form) or globally unique (e.g. in URL form), by which the application server can use the services specified in the SLA provided by the mobile network.

Step 601, step 604 to step 609, and step 611 are taken as a first embodiment, and the following step 602 and step 603 are taken as a scheme of a second embodiment based on a modification of the first embodiment.

Step 602: optionally, the short-range application on the UE sends a discovery request to the application server through the 202 interface, where the discovery request may carry user information.

For example, the user information may include one or more of: application layer user identity, General Public Subscription Identity (GPSI).

When the link of the application server and the UE can be used to identify the application layer user identity, the application layer user identity may not be included in the user information.

When the UE has sent the common public subscription identity to the application server through other interactive processes, the user information may not include the common public subscription identity.

Further, the user information may be distributed and sent to the UE by unified data management during the UE accessing the mobile network.

Further, the discovery request may also carry time information, such as a duration or an expiration time, for indicating the termination of the discovery process, and further, the discovery request may also carry interval information for indicating an interval between two times of broadcasting the direct communication request through the 201 interface.

Step 603: the application server receives the discovery request of step 602, and optionally sends a discovery response to the short-range application on the UE through the 202 interface, where the discovery response may carry mode information.

Further, the discovery response may also carry discovery code information, which may include one or more of the following: an application Code (App Code), a Response Code (Response Code), an application Code Filter (App Code Filter), and an application Code Filter (App Code Filter).

For example, the discovery code information includes: the application Code (App Code), or the application Code (App Code) + the Response Code Filter (Response Code Filter), or the Response Code (Response Code) + the application Code Filter (App Code Filter), or the application Code App Code + the application Code Filter (App Code Filter), or the application Code (App Code) + the Response Code Filter (Response Code Filter) + the Response Code (Response Code Filter) + the application Code Filter (App Code Filter).

The App Code Filter comprises a plurality of App Code information, and the Response Code Filter comprises a plurality of Response Code information.

If the short-range function on the UE receives the App Code Filter, when monitoring a broadcast message carrying the App Code from other terminals, the short-range function can judge whether the App Code is in the App Code Filter, if so, the broadcast message is processed, otherwise, the broadcast message is discarded.

If the short-range function on the UE receives the Response Code Filter, after the broadcast message carrying the App Code and the receiving address is sent, when the message carrying the Response Code sent to the receiving address from other terminals is monitored, whether the Response Code is in the Response Code Filter is judged, if yes, the message is processed, and if not, the message is discarded.

Step 604: the application server sends a request for starting the short-distance communication service to a Network capability Exposure Function (NEF).

For example, a Create (Create) or Update (Update) procedure of the NEF _ ServiceParameter service of the NEF is invoked, the parameter includes a user identifier, such as GPSI, or the parameter may further include an activation indication for indicating whether to activate the near discovery service, which may be activated by a Create operation type and a near communication service type indication, or may also indicate whether to activate the near communication information, such as "1" indicates activation, and "0" indicates deactivation.

Optionally, the activation indication may further comprise one or more of: the application identifier (App ID), interval information, and duration information, and further, the activation indication may further include the discovery code information described in step 603.

Step 604 may be triggered by step 602 or step 604 may also be triggered by the application server as needed.

When triggered by the application server, the UE and the application server are required to interact with the user identity of the UE in advance, and the interval information is received from a short-range application on the UE or is autonomously generated by the application server.

Step 605: the NEF interacts with the unified data management to judge whether the user is allowed to use the short-distance communication service for the corresponding application in the corresponding service network according to one or more items of the user identification, the service network where the user is located, the application information and the subscription information, wherein the unified data management can be a network function UDM or two network functions UDM and UDR, and the interaction can be interaction with the UDM or interaction with the UDR.

For example, the NEF calls a Get (Get) operation of the numm _ subscriber data management service of the unified data management function to obtain subscription information and service network information of the user, and then determines whether the user is allowed to use the short-range communication service for the corresponding application in the corresponding service network.

The NEF may also only determine whether the user is allowed to use the short-range communication service, or the NEF only determines whether the user is allowed to use the short-range communication service for the corresponding application, or the NEF only determines whether the user is allowed to use the short-range communication service in the corresponding service network.

The unified data management function may also return a new application identifier (App ID) to the NEF, for example, the application identifier received by the NEF is a globally unique identifier, and the unified data management function returns a unique identifier within a mobile network.

Step 606: the NEF invokes a parameter creation or update procedure for unified data management, where the interaction may be with the UDM or with the UDR.

Such as a Create or Update procedure that calls the Nudr _ DataManagement service.

The parameter may include a user identification.

Alternatively, the parameters may also include one or more of: application identification (received from an application server or unified data management), discovery code information, and an activation indication.

Alternatively, the parameters may also include one or more of: interval information and time information, wherein the interval information or the time information may be received from an application server or autonomously generated by the NEF.

Step 607: the unified data management function invokes a parameter change notification for the policy control function.

The parameters may include a user identification if a Notify operation of the Npcf _ EventExposure service is invoked.

Alternatively, the parameters may also include one or more of: application identification, discovery code information, activation indication.

Alternatively, the parameters may further include: interval information, time information, where interval information or time information may be received from the NEF or autonomously generated by unified data management.

Step 608: the policy control function invokes a policy notification of the access management function.

Such as a Notify operation that invokes a Namf _ EventExposure service, the parameters include a user identification.

Alternatively, the parameters may also include interval information, time information, wherein the interval information or time information may be received from a policy control function or autonomously generated by an access management function.

Step 609: the access management function sends a terminal configuration message to the terminal over the 205 interface.

For example, a terminal Configuration Update (UE Configuration Update) message is sent, and the UE Configuration Update message may carry one or more of the following items: application identification, discovery code information, activation indication, interval information, time information, wherein interval information or time information may be received from a policy control function or autonomously generated by an access management function.

The following steps 610, 612, and 613 are based on the modified third embodiment of the first embodiment or the second embodiment.

Step 610: optionally, after step 601, the near application on the UE may subscribe to near discovery to the near function on the UE, and the subscription parameter may include interval information configured by the terminal side or set by the near application.

For a third embodiment modified from the second embodiment, if step 603 is performed, the parameters may also contain the received discovery code when step 610 is performed after 603.

Step 611: and sending the broadcast message carrying the discovery code on the 201 interface at intervals, and monitoring the message on the 201 interface when the broadcast message is not sent.

The short-range function on the UE receives the message in step 609 and starts the short-range discovery service according to the activation indication, or the discovery code, or the application identifier.

If the third embodiment performs step 610, when step 610 and step 609 include the same kind of information (such as a discovery code or spacing information), the short-range function uses the information in step 609, and if the spacing information is not received, the short-range function uses the autonomously generated spacing information.

If the found Code is an application Code (App Code), the short-distance function broadcasts a direct communication request at intervals through a 201 interface, the direct communication request can carry the App Code, and further, the direct communication request can also carry a receiving address;

if the found Code is an application Code (App Code) + Response Code Filter (Response Code Filter), the short-range function broadcasts a direct communication request at intervals through a 201 interface, the direct communication request can carry the App Code, further, the direct communication request can also carry a receiving address, and monitors a direct communication Response message carrying the Response Code and sent from other terminals to the terminal through the 201 interface;

if the Code is found to be a Response Code (Response Code) + an application Code Filter (App Code Filter), the short-range function monitors a direct communication request carrying the App Code and broadcasted from other terminals through a 201 interface, further, the direct communication request can also carry a receiving address, and after receiving the direct communication request, the short-range function sends the Response Code to a direct communication request broadcaster through the 201 interface;

The stop request may carry user information, for example, the user information includes one or more of the following: application layer user identity, General Public Subscription Identity (GPSI).

The user information is distributed and sent to the UE by unified data management in the process that the UE accesses the mobile network.

Further, the stop request may also be represented by a discovery request carrying time information of "0".

The stop request may not contain an application layer subscriber identity when the application server and UE link is available to identify the application layer subscriber identity.

The stop request may not include the common public subscription identity when the UE has sent the common public subscription identity to the application server through other interactive processes.

Step 709: the access management function sends a terminal configuration message to the terminal over the 205 interface.

For example, the UE Configuration Update message is sent, and optionally, the UE Configuration Update message may carry the application identifier and/or the activation indication.

Step 710: the short-range function on the UE receives the message in step 709 and stops short-range discovery service according to the activation indication and/or the application identifier.

The user information is distributed and sent to the UE by unified data management in the process that the UE is accessed to the mobile network.

Optionally, the discovery request may also carry time information, such as a duration or an expiration time, for indicating termination of the discovery process.

Wherein, when the link of the application server and the UE can be used to identify the application layer user identity, the user information may not contain the application layer user identity.

Step 803: the application server receives the discovery request of step 802, and optionally sends a discovery response to the short-range application on the UE through the 202 interface, where the discovery response may carry mode information, or the discovery response may also carry a discovery code.

It should be noted that the description of the discovery code in step 803 may refer to the description of the discovery code in step 603, and will not be described here.

Step 804: the application server sends a request for initiating the short-range communication service to a network capability opening function (NEF).

Alternatively, the parameters may further include: application identification (App ID).

Alternatively, the parameters may further include: interval information and/or time information.

Alternatively, the parameter may also contain a discovery code.

Step 804 may be triggered by step 802, or step 804 may also be triggered by the application server as needed, when triggered by the application server itself, requiring the UE and the application server to interact with the user identity of the UE in advance.

Step 805: the NEF interacts with the unified data management function to judge whether the user is allowed to use the short-distance communication service for the corresponding application in the corresponding service network according to one or more items of the user identification, the service network where the user is located, the application information and the subscription information.

Step 806: the NEF invokes a parameter creation or update procedure of the unified data management function.

The parameters may include: the user identification, or the parameters may further include one or more of: application identification (received from an application server or unified data management), discovery code information, activation indication, time information.

Step 807: the unified data management function invokes a parameter change notification for the policy control function.

If a Notify operation of the Npcf _ EventExposure service is invoked, the parameters may include: the user identification, or parameters, may also include one or more of: application identification, discovery code information, activation indication, time information.

Step 808: the policy control function invokes a policy notification of the access management function.

For example, the Notify operation for calling the Namf _ eventeissue service includes the following parameters: the user identification, or parameters, may also include one or more of: application identification, discovery code information, activation indication, time information.

Step 809: the access management function sends a terminal configuration message to the terminal over the 205 interface.
