Description

Short-distance service registration method and device

The present invention relates to the field of network communication technologies, and in particular, to a proximity service registration method and apparatus.

Background technique

Proximity service (ProSe) is a newly emerging communication service. The primary use of proximity services is to enable direct communication between terminals.

For example, two terminals that support close-range services can directly conduct voice communication through close-range services. The data in the communication process does not need to pass through the base station, the mobile management entity of the core network or the gateway, and the two terminals can use a specific frequency band to realize data transmission.

The use of close-range services requires the terminal to register on the mobile network. In the prior art, the registration method of the short-distance service is mainly: the terminal registers its own ID and the settings of the close-range service to the network; the network stores related information and allocates a broadcast code for the short-range device broadcast to the device (Broadcast Code) ₀ after registration is completed, when the terminal requests a service for close, the server needs to send a request to close; close server after receiving the request, the mobility management entity needs (mobility management entity, MME) sends a request; the MME receives After the request sent by the proximity server, it checks whether the network where the terminal is located supports short-distance services. When the network does not support the short-distance service, the MME interacts with the proximity server to inform the proximity server that the network where the terminal is located does not support the proximity service; finally, the proximity server rejects the request of the terminal.

It can be seen from the above that in the prior art, when the terminal is in the network that does not support the short-distance service and requests to initiate the short-distance service, multiple signaling interactions between the short-distance server and the MME are required, resulting in a large signaling overhead of the communication system.

The technical solutions in the embodiments of the present invention are clearly and completely described in the following with reference to the accompanying drawings in the embodiments of the present invention. It is obvious that the described embodiments are only a part of the embodiments of the present invention, but not all of the embodiments. Based on the embodiments of the present invention, one of ordinary skill in the art does not create All other embodiments obtained under the premise of sexual labor are within the scope of protection of the present invention. First of all, it should be noted that the short-distance service referred to in the present application refers to a service in which a terminal can discover another terminal in a physical close range and can perform optimized communication with another terminal. The optimized communication may be that the communication data between the terminals may be directly transmitted through the agreed frequency band between the terminals without going through the mobile operator's network. Specifically, the short-distance service includes: a service that directly performs voice data transmission between the terminals to implement a call, and directly performs file data transmission between the terminals to implement file transmission, and directly transmits short message data between the terminals to implement sending and receiving short messages. Business and so on.

FIG. 1 is a flowchart of Embodiment 1 of a short-distance service registration method according to the present application. As shown in Figure 1, the method can include:

Step 101: The terminal determines whether the network supports the short-distance service; the network is the network where the terminal is currently located, or the network to which the terminal is to be switched;

The terminal may be a device such as a mobile phone that supports short-distance services. The terminal can pass through the base station

The broadcast of (EvolvedNode B, eNodeB) obtains the close-range service capability information of the network. The short-range service capability information may indicate whether the network supports short-range services. The base station may obtain the short-distance service capability of the network where the terminal is located through a signaling interaction process with the mobility management entity (MME), or obtain the network where the terminal is located by using configuration information stored in the base station itself. Close-range business capabilities. Specifically, the MME may carry the short-range service capability information of the network in the SI signaling that establishes the SI process with the eNodeB in the prior art. The eNodeB can learn the short-distance service capability of the network according to the short-range service capability information in the S1 signaling.

The network may be the network where the terminal is currently located, or may be the network to which the terminal is to be switched.

Step 102: When the network supports the short-distance service, send a registration request for starting the close-range service to the short-distance service server.

The proximity server can obtain the subscription information of the terminal. The subscription information records information about whether the terminal has opened a close-range service. If the terminal has opened the proximity service, the proximity service server may start the proximity service of the terminal after receiving the registration request for opening the proximity service; if the terminal is not opened yet After the proximity service server receives the registration request to enable the proximity service, the proximity service server may refuse to open the proximity service of the terminal. Step 103: When the network does not support the short-distance service, send a registration request to close the close-range service to the proximity service server.

If the short-distance service is enabled in the previous registration process, the short-distance service server may close the short-distance service of the terminal after receiving the registration request to close the short-range service. If the terminal does not open the proximity service during the previous registration process, the proximity service server may not respond after receiving the registration request to close the proximity service.

The relationship between step 102 and step 103 is a relationship between the foregoing steps, that is, there may be an embodiment including step 101, step 102 and step 103, and an embodiment including step 101 and step 102 may be present, and step 101 may be included. And the embodiment of step 103.

In summary, the short-distance service registration method in this embodiment determines whether the network supports the short-distance service, so that when the terminal registers on the network, the network can learn the capability of the network to support the short-distance service, thereby avoiding that the terminal is not supported. In the case of a close-range service request in a network of short-haul services, the signaling overhead of the communication system is reduced. Referring to FIG. 2, it is a flowchart of Embodiment 2 of the short-distance service registration method of the present application. The process can include:

Step 201: The base station (eNodeB) sends an S1 establishment request to the mobility management entity (MME). Step 202: The MME sends an S1 setup response to the eNodeB. The S1 setup response includes ProSe capability information of the network.

Step 201 and step 202 are optional steps. The eNodeB and the MME interact with each other through the S1 establishment process of the existing S1 signaling, and obtain the ProSe capability information of the network. The ProSe capability information can indicate whether the network can support the ProSe service. If the eNodeB can obtain the ProSe capability information of the network according to the configuration information, the above two steps can be skipped.

Step 203: The base station sends a broadcast of the short-distance service capability of the network to the user equipment. Step 204: The user equipment sends a short-distance service request to the MME. The request may include the user equipment identifier, and information about enabling or closing the close-range service. .

The user equipment may determine, according to the received broadcast, whether the network supports the short-distance service; when the network supports the short-distance service, the MME may send a registration request for opening the short-distance service to the short-distance service server by using the MME; When the network does not support the short-distance service, the MME may send a registration request to close the short-range service to the short-distance service server.

The request may include a user equipment identifier, and information for turning on or off the close-range service, and may also include setting information for the close-range service.

The device identifier may be the IMSI or MSISDN of the device or the temporary identifier of the device assigned by the network. The message may use an existing network attach request message, or a non-access stratum (NAS) message such as a location update message, or an access stratum (AS) message sent by the device to the MME through the base station.

The setting information may be close-range discovery configuration information of the user equipment. The configuration information found at close range can include: "You can find others, but you can't be discovered by others." "You can find that others can be discovered by others." "You can't find others, you can't be discovered by others." "You can't find others." But it is allowed to be discovered by others. "Every time I ask if I am allowed to be discovered by the other party", I am allowed to discover my own device identification list, and I am not allowed to find my own device identification list.

Step 205: The MME forwards the short-range service request sent by the user equipment to the ProSe Server.

Step 206: After receiving the short-range service request, the short-distance service server determines whether the user equipment allows the short-distance service. If allowed, the proximity service request is accepted; if not allowed, the device's proximity service request is rejected.

The proximity service server can send the device identification to the Home Subscriber Server (HSS), and obtain the subscription data of the device from the HSS. The contract data includes information on whether the device is allowed to perform close-range services. The proximity service server can determine whether to allow the close-range service of the device according to the obtained subscription data. If the proximity service server has obtained the device subscription data before, it does not need to obtain the device from the HSS. It can directly determine whether to allow the device to be close-range service according to the device subscription data saved locally by the proximity service server.

Step 206: The proximity server sends a close proximity service accept message to the MME. The short-range service acceptance message may include a device-to-device identification (D2D ID) and a device-to-device password (D2D Code) allocated for the user equipment.

The short-distance service server can allocate the D2D Code and the D2D ID to the device, and can also save the received user equipment identifier and the setting information of the user equipment for the close-range service.

The ProSe settings of the proximity device and the D2D Code and D2D ID assigned to the device. The optional proximity service server saves the device's close-range discovery configuration information. In step 206, the short-distance service server can provide its own routing information to the device, so that the device can provide the obtained short-distance service server routing information to the application layer server in the subsequent application layer interaction, and the application layer server according to the route. The information can be found by the proximity service server registered by the device for message interaction to obtain a close-range business service. The routing information may be a server identifier of the proximity service server, such as but not limited to a Uniform Resource Identifier (URI), or may be in the form of an IP address or the like.

The proximity service server can also carry routing information in the D2D ID assigned to the device, for example, the D2D ID assigned to the device is defined as "device d2d id@proximityserver URI". Or different short-distance service servers can use different D2D ID ranges, so that the device provides the D2D ID to the application layer server in the subsequent application layer interaction, and the application layer server can directly extract the close distance from the D2D ID. The routing information of the service server, or the routing information of the corresponding short-distance service server is found according to the range of the D2D ID, so that the short-distance service support can be obtained from the short-distance service server.

Optionally, the short-range service server allocates a decryption key to the short-range device, and sends the information to the user equipment by using the MME in this step. When the subsequent user equipment obtains the encrypted content from the proximity service server through the application layer server, the decryption key can be used for decryption.

Step 207: The MME forwards the short-range service accept message to the user equipment.

It can be sent through a NAS message, or sent to the device through the base station using an AS message. Step 208: The user equipment sends a device to device service registration request (D2D Service Registration Request) to the application layer server (Application Server). The device-to-device service registration request may include a device-to-device identification (D2D ID).

The user equipment may send a D2D service registration request to the application server, where the D2D ID assigned by the proximity service server to the device is carried, and the application server saves the D2D ID. Optionally, the D2D ID can carry the routing information of the short-distance service server, and the application server can route the information to the corresponding short-distance service server, and determine the legality of the D2D ID through the short-distance service server. If not, the application server The D2D service registration request can be rejected.

Step 209: The application layer server sends a D2D Code update message to the MME.

Step 209 is an optional step. If the short-distance service server receives the D2D service registration request sent by the application server, and confirms that the D2D ID is valid, the device may allocate a new D2D code according to the specifically registered application. This D2D Code is related to the registered application. Close-range business Send the updated D2D Code to the MME. If no new D2D Code is assigned, skip this step. Step 210: The MME forwards the D2D Code update message to the user equipment.

It should be noted that, in this embodiment, the user equipment may also fail to communicate with the proximity service server.

The MME performs direct interaction. In the case of direct interaction, the MME may forward the message forwarding procedure between the proximity service server and the user equipment.

After the terminal (ie, the user equipment) completes the registration process, it is possible to enter a new cell. The cell can be the smallest unit of the ProSe-enabled network. The concept of the Tracking Area (ΤΑ) below is greater than the cell. A tracking area can include multiple cells. When the terminal enters a new cell, the following method can be used.

When the terminal enters a new cell, it may be determined whether the cell supports the short-range service; when the short-distance service capability of the cell changes with respect to a short-distance service capability of a cell to which the terminal belongs, the terminal You can initiate a process to change the proximity business settings. Specifically, the short-distance service capability of the cell changes, including two cases: The first case is that the terminal enters a cell that does not support the short-distance service by the cell supporting the short-distance service; the second case is that the terminal does not support the close-range The cell of the service enters a cell supporting the short-distance service.

In the first case, when the cell does not support the short-range service, the first tracking area update request including the short-range service closing information is sent to the base station, so that the base station sends the first tracking area update request. Forwarding to the mobility management entity, the mobility management entity sends a request to close the proximity service to the proximity service server.

In the second case, when the cell supports the short-range service, the second tracking area update request including the short-range service configuration information may be sent to the base station, so that the base station sends the second tracking area update request. Forwarding to the mobility management entity, the mobility management entity sends a request to open the proximity service to the short-range service server, and the proximity service server starts the proximity service according to the short-range service configuration information .

Figure 3 is a flow chart of the terminal changing the close-range service setting when the capability of the cell changes. As shown

As shown in 3, the process can include:

Step 301: The base station generates a broadcast carrying the network capability information to the user equipment. The network capability information may indicate whether the new cell supports short-range traffic.

The user equipment can determine whether the short-distance service capability of the network changes according to the broadcast. If a change occurs, step 302 can be triggered. Step 302: The user equipment sends a tracking area update request (TAU Request) to the base station. Among them, TAU is an abbreviation of Tracking Area Update. The tracking area update request can be implemented by using existing signaling in the existing TAU process to carry corresponding indication information. The tracking area update request needs to carry indication information. The indication information may be indication information indicating that the proximity service is turned on or off.

Step 303: The base station forwards the tracking area update request to the MME.

Step 304: The MME sends a request for opening or closing the proximity service to the proximity server according to the indication information in the tracking area update request.

The proximity service server can determine whether to allow the ProSe service of the device from the registration information. If the proximity service server determines that the device is not allowed to use the ProSe service, the proximity service request information is rejected. If the proximity service server determines that the ProSe service of the device is allowed, the ProSe setting of the device update is stored, and step 305 is performed.

Step 305: The proximity service server sends a short-range service accept message to the MME. This message can indicate that the Proximity Service Server has successfully updated the ProSe settings of the device.

Step 306: The MME sends a tracking area update response (TAU Response) to the base station, and informs the base station that the TAU process has been successfully executed.

Step 307: The base station forwards the tracking area update response to the user equipment, and informs the user equipment that the TAU process has been successfully performed, and successfully updates the ProSe setting of the device.

It should be noted that the user equipment may have two states: a connected state and an idle state. When the user equipment is in an idle state, the method in FIG. 3 can be directly adopted. When the user equipment is in the connected state, it is necessary to increase the handover procedure between step 301 and step 302. The handover procedure may switch the user equipment from the source eNodeB to the target eNodeB and switch the data to the new eNodeB, so that the data is transmitted from the new eNodeB to the core network for transmission. In the connected state, data is transmitted through the core network in the original network and the switched network, rather than through the D2D connection. The application also provides a proximity service update method. 4 is a flow chart of Embodiment 1 of the proximity service update method of the present application. The process can include:

Step 401: The base station sends an S1 establishment request to the MME.

The S1 setup request may include the short-range service capability information of the base station. The short-range service capability information may indicate whether the network to which the terminal is to be switched supports short-range services.

Step 402: The MME stores the ProSe capability information of the network, and sends an S1 setup to the eNodeB. The response message informs the eNodeB of the corresponding information.

Step 403: The base station sends a broadcast to the user equipment to notify the user whether the cell switched by the device supports the ProSe service.

Step 404: The user equipment sends a tracking area update request to the base station.

The tracking area update request can be implemented using existing signaling in an existing TAU flow. Compared with the process in Figure 3, the tracking area update request in this process does not carry indication information.

Step 405: The base station forwards the tracking area update request to the MME.

After receiving the request, the MME determines, according to the short-range service capability information of the network stored in step 401, whether the capability of the cell in which the user equipment is located is changed relative to the new cell that is about to enter. If the near-field service capability changes, step 406 is performed.

Step 406: The MME generates a close-range service request to the proximity server.

The short-range service request may be a request to open a close-range service, or may be a request to close a close-range service.

The proximity service server can determine whether to allow the ProSe service of the device from the registration information. If the proximity service server determines that the device is not allowed to use the ProSe service, the proximity service request information is rejected. If the proximity service server determines that the ProSe service of the device is allowed, the ProSe setting updated by the user device is stored.

It should be noted that the short-range service request may further include short-distance service configuration information of the user equipment.

The short-range service configuration information includes: configuration information about whether the terminal can discover other terminals, and/or configuration information about whether the terminal can be discovered by other terminals.

Step 407: The proximity service server sends a short-range service accept message to the MME. This message can indicate that the Proximity Service Server has successfully updated the ProSe settings of the device.

Step 408: The MME sends a tracking area update response (TAU Response) to the base station, and informs the base station that the TAU process has been successfully executed.

Step 409: The base station forwards the tracking area update response to the user equipment, and informs the user equipment that the TAU process has been successfully performed, and successfully updates the ProSe setting of the device.

In this embodiment, the MME detects whether the short-distance service capability of the network changes, and may enable the user equipment to send the tracking area update request according to the manner in the prior art, without modifying the tracking area update request message. FIG. 5 is a flowchart of Embodiment 2 of a short-range service update method according to the present application. As shown in FIG. 5, the process may include:

Step 501: The base station sends an S1 establishment request to the MME.

Step 502: The MME stores the ProSe capability information of the network, and sends an S1 setup response message to the eNodeB to notify the eNodeB of the corresponding information.

In this embodiment, the TAs having the same short-range service capability may be stored in a TA list, and the user equipment may determine whether the newly entered cell belongs to the current TA list. If yes, the subsequent steps are not performed; if not, Then step 503 is performed.

In this embodiment, since the TA list is set, the step of transmitting the broadcast message to the user equipment by the base station can be omitted as compared with the embodiment in FIG.

Step 503: The user equipment sends a tracking area update request to the base station.

Step 504: The base station forwards the tracking area update request to the MME.

After receiving the request, the MME determines, according to the short-range service capability information of the network stored in step 501, whether the capability of the TA that the user equipment is in before is changed with respect to the new TA that is about to enter. If the near-field service capability changes, step 506 is performed.

Step 505: The MME generates a close-range service request to the proximity server.

The short-range service configuration information includes: configuration information about whether the terminal can discover other terminals, and/or configuration information about whether the terminal can be discovered by other terminals. Step 506: The proximity service server sends a short-range service accept message to the MME. The message may indicate that the Proximity Service Server has successfully updated the ProSe settings of the device.

Step 507: The MME sends a tracking area update response (TAU Response) to the base station, and informs the base station that the TAU process has been successfully executed.

Step 508: The base station forwards the tracking area update response to the user equipment, and informs the user equipment that the TAU process has been successfully performed, and successfully updates the ProSe setting of the device.

It should be noted that when the user equipment enters a new cell in an idle state, the method in FIG. 4 or FIG. 5 may be directly used. When the user equipment enters a new cell in the connected state, the step of determining the network capability of the MME may be added in the handover procedure. See Figure 6 for details.

FIG. 6 is a flowchart of Embodiment 3 of the short-range service update method of the present application. The process may include: Step 601: The base station sends an S1 establishment request to the MME.

Step 602: The MME stores the ProSe capability information of the network, and sends an S1 setup response message to the eNodeB to notify the eNodeB of the corresponding information.

The connected user equipment enters the new TA, receives the ProSe capability of the network in which the eNodeB broadcasts, and then prepares and executes the handover, and transfers the data from the source eNodeB to the target eNodeB, ready to complete the handover completion process.

Step 603: The base station sends a path switch request to the MME.

The target eNodeB sends a Path Switch Request message to the MME to inform the MME that the device has entered the new cell. This message is a message defined in the existing handover process.

After receiving the request, the MME determines, according to the short-range service capability information of the network stored in step 601, whether the capability of the cell in which the user equipment is located is changed relative to the new cell that is about to enter. If the near-field service capability changes, step 604 is performed.

Step 604: The MME generates a close-range service request to the proximity server.

It should be noted that, in the short-range service request, the short-distance industry of the user equipment may also be included. Configuration information.

Step 605: The short-range service server sends a short-range service accept message to the MME. This message can indicate that the Proximity Service Server has successfully updated the ProSe settings of the device.

Step 606: The MME sends a path switch request acknowledgement message to the base station, indicating that the handover has been successfully performed.

If the trigger condition of the TAU process is met, the tracking area update process can also be performed.

The method in this embodiment can be applied to update the related settings of the proximity service when the user equipment in the connected state enters the new cell.
