End-to-end (English: Device to Device, D2D) service, which can also be called Proximity Service (English: ProSeimity Service, ProSe), means that the data of the user equipment can be directly between the user equipments without going through the network. Transfer.

A D2D trunk service refers to a user equipment that is outside the network coverage or whose current network signal quality is poor, and communicates with the network through a relay user equipment. The relay user device can communicate directly with the network. A user equipment that needs to communicate with the network through a relay user equipment may be referred to as a remote user equipment.

The Listening Center (English: Law Enforcement Agency, LEA for short) is a department that has the right to request the operator to monitor the information in the communication of the user equipment. The LEA can analyze the information monitored by the operator or use the information monitored by the operator as evidence. A device in the LEA that is responsible for determining and delivering information that needs to be monitored may be referred to as a listening center device. The information may include interception related information (English: Interception Related Information, IRI for short) and communication content (English: Content of Communication, CC for short), wherein the interception related information refers to signaling messages and network management information. The network device used for monitoring the user equipment may be referred to as a ProSe Function (English: ProSe Function). The proximity service server can send the information of the monitored user equipment to the LEA.

detailed description

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 embodiments are a part of the embodiments of the present invention, but not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without creative efforts shall fall within the scope of the present invention.

It should be understood that the technical solution of the embodiment of the present invention may be applied to a Long Term Evolution (LTE) system.

A user equipment (User Equipment, UE) may also be called a mobile terminal (MT), a mobile user equipment, etc., and may be performed by using a radio access network (for example, a Radio Access Network, RAN) and one or more core networks. Communication, the user equipment can be a mobile terminal, such as a mobile telephone (or "cellular" telephone) and a computer with a mobile terminal, for example, a mobile device that can be portable, pocket, handheld, computer built, or in-vehicle.

FIG. 1 is a schematic diagram of a D2D relay service. As shown in Figure 1, user equipment 101 can communicate directly with the network. User equipment 102 is located outside of network coverage or within network coverage but has poor signal quality. In this case, the user equipment 102 can communicate with the network through the user equipment 101. User equipment 101 may be referred to as a relay user equipment, and user equipment 102 may be referred to as a remote user equipment.

The remote user equipment in the D2D trunk service may include two types of remote user equipments, a first type of remote user equipment and a second type of remote user equipment. The first type of remote user equipment refers to a remote user equipment that is outside the network coverage. The second type of remote user equipment refers to user equipment that is located in the network coverage but has poor network quality. The first type of remote user equipment cannot communicate with the network because it is outside the network coverage. In this case, the first type of remote user equipment needs to communicate with the network through the relay user equipment. Although the second type of remote user equipment is located in the network coverage, the current network signal quality of the second type of remote user equipment is not good, which results in the quality of the second type of remote user equipment directly communicating with the network. Therefore, the second type of remote user equipment also needs to pass the relay user. The device communicates with the network. The remote user equipment referred to in the specification of the present invention includes a first type of remote user equipment and/or a second type of remote user equipment, unless otherwise specified.

There is only one close-range service server in a public land mobile network (English: Public Land Mobile Network, PLMN for short). The user equipment can only communicate with the proximity service server in the PLMN (referred to as the "home network") to which it belongs. For a user equipment, there is only one PLMN for the user equipment. For convenience of description, the short-distance service server of the home network of the remote user equipment may be referred to as a first short-distance service server, and the short-distance service server of the home network of the relay user equipment may be referred to as a second short-distance service. server. It is easy to understand that if the remote user equipment and the relay user equipment belong to the same PLMN, the first short-distance service server and the second short-distance service server are the same short-distance service server.

FIG. 2 is a schematic flowchart of a listening method according to an embodiment of the present invention. The interception center device may send the interception object information to the first close proximity service server or the second proximity service server. The proximity service server in FIG. 2 is a proximity service server that receives the interception object information.

201. The relay user equipment receives an access request sent by the remote user equipment, where the access request includes first identifier information of the remote user equipment.

Optionally, as an embodiment, the first identifier information may be at least one of the following IMSI, IMEI, and MSISDN. Optionally, in another embodiment, the first identifier information may also be at least one of the following: a TMSI, a proximity service discovery user equipment identifier, and a temporary identifier. The temporary identifier may be a newly defined identifier for temporarily identifying the user equipment. The temporary identifier may be an identifier that is temporarily allocated to the user equipment by the device in the network (for example, the base station, the network side device (including: MME, HSS, etc.)) or an identifier temporarily determined by the user equipment. The temporary identity is not any of IMSI, IMEI, and MSISDN. The temporary identity corresponds to any one or more of IMSI, IMEI, and MSISDN. The correspondence between the temporary identifier and at least one of the IMSI, the IMEI, and the MSISDN may be stored in the base station or the network side device.

202. The relay user equipment sends the first identifier information of the remote user equipment to the proximity service server.

It can be understood that, if the short-distance service server is the first short-distance service server, the relay user equipment sends the first identifier information of the remote user equipment to the close distance through the second short-distance service server. Business server.

203. The proximity service server may obtain an IMSI, an IMEI, and an IMEI of the remote user equipment. At least one of the MSISDNs.

Optionally, in an embodiment, in step 201, if the first identifier information is at least one of the following IMSI, IMEI, and MSISDN, the proximity service server may directly obtain the corresponding identifier. For example, if the first identification information is an IMSI, the proximity service server can directly obtain the IMSI. For another example, if the first identification information is an IMEI, the proximity service server can directly obtain the IMEI.

Optionally, in another embodiment, in step 201, if the first identifier information is at least one of the following TMSI, the proximity service discovery user equipment identifier, and the temporary identifier, the proximity service server may be configured according to the The second identifier information of the remote user equipment is determined by the correspondence between the identifier information and the second identifier information, where the second identifier information is at least one of the following IMSI, IMEI, and MSISDN. Optionally, in an embodiment, the proximity service server may send the first identifier information (ie, at least one of a TMSI, a short-distance service discovery user equipment identifier, and a temporary identifier) to the HSS. And a request message, configured to request a correspondence between the first identification information and the second identification information (ie, at least one of an IMSI, an IMEI, and an MSISDN). The HSS may send the correspondence between the first identification information and the second identification information to the proximity service server if the request message is received. Optionally, as another embodiment, the proximity service server may maintain a ProSe context, where the ProSe context includes a correspondence between the first identifier information of the remote user equipment and the second identifier information of the remote user equipment. . In this way, the proximity service server can determine the second identity information of the remote user equipment. Specifically, the remote user equipment may have established a connection with the proximity service server, and sent the first identifier information of the remote user equipment to the proximity service server. In this case, the proximity service server may request the HSS to obtain a correspondence between the first identifier information and the second identifier information, so as to determine the second identifier information of the remote user equipment. In this way, the proximity service server may store a ProSe context, where the ProSe context includes a correspondence between the first identifier information of the remote user equipment and the second identifier information of the remote user equipment. It can be understood that, if the short-distance service server is the second short-distance service server, the proximity service server can obtain the correspondence between the first identifier information and the second identifier information by using the first proximity service server. . The manner in which the first proximity service server obtains the correspondence between the first identifier information and the second identifier information is the same as the foregoing manner.

For convenience of description, the following uses the permanent identification information to refer to the first identification information or the second identification information. Specifically, if the first identifier information in step 201 is IMSI, IMEI, and MSISDN, Any one of the permanent identification information is the first identification information. If the first identification information in step 201 is any one of a TMSI, a short-distance service discovery user equipment identifier, and a temporary identifier, the permanent identifier information is the second identifier information in step 203.

If the first identifier information is the TMSI, the proximity service discovery user equipment identifier, and the temporary identifier, the IMEI, the IMSI, and the MSISDN of the remote user equipment are not in the remote user equipment, the relay user equipment, and the proximity service server. Transfer between the three. This prevents the IMEI, IMSI, and MSISDN of the remote user equipment from being monitored by others, and avoids the security risks caused by leaking the IMEI, IMSI, and MSISDN of the remote user equipment.

204. The proximity service server may determine, according to the permanent identifier information of the remote user equipment, whether to listen to the remote user equipment.

Specifically, the proximity service server may determine whether the remote identifier information of the remote user equipment is included in the interception object information, where the interception object information includes permanent identification information of at least one object that needs to be monitored. If the proximity service server determines that the interception object information includes permanent identification information of the remote user equipment, determining to listen to the remote user equipment; if the proximity service server determines that the interception object information does not include the remote user equipment Permanently identifying the information determines that the remote user device is not being listened to. It can be understood that the proximity service server needs to implement the acquisition of the interception object information. The interception object information is obtained by the proximity service server from the interception center device. The interception center device can determine the permanent identification information of the object to be monitored in advance, and send the permanent identification information of the object to be monitored to the proximity service server in each PLMN.

Those skilled in the art can understand that there is also a correspondence between IMEI, IMSI and MSISDN. The proximity service server may obtain other identifiers when obtaining any one of the IMEI, the IMSI, and the MSISDN. For example, if the first identity information obtained by the proximity service server from the relay user equipment is an IMEI and the permanent identity information in the interception object information is an IMSI, the proximity service server may be based on the IMSI and the IMEI. Corresponding relationship, determining the IMSI of the remote user equipment, and determining whether the IMSI of the remote user equipment is included in the interception object information. In other words, the specific identifier of the permanent identifier information in the interception object information and the specific identifier in the permanent identifier information acquired by the proximity service server may not be identical, but the proximity service server can be based on IMEI, IMSI, and The correspondence between the three MSISDNs determines a specific identifier that can be used to match the permanent identification information in the interception object information.

The method shown in FIG. 2 may further include steps 205 to 209, or step 210 to step Step 215.

205. If it is determined to listen to the remote user equipment, the proximity service server sends the permanent identifier information of the remote user equipment to the monitoring center device.

It can be understood that the proximity service server may not need to send the permanent identity information of the remote user equipment to the interception center device immediately after determining to listen to the remote user equipment. The proximity service server may periodically send the monitored permanent identification information to the monitoring center device when determining to listen to the remote user equipment, or may send the request for receiving the monitoring center device. After the indication of the monitored permanent identification information is reported, the monitored permanent identification information is sent to the monitoring center device. Therefore, the proximity service server may further store the permanent identification information of the remote user equipment, so as to send the permanent identification information of the remote user equipment to the monitoring center device when determining the need. After receiving the permanent identification information sent by the short-distance service server, the monitoring center device may determine the time when the object corresponding to the permanent identifier information accesses the network and the object corresponding to the permanent identifier information accesses the network. After determining that the object corresponding to the permanent identifier information is connected to the network, the monitoring center device may perform a series of operations according to requirements, for example, determining location information of the object corresponding to the permanent identifier information.

206. The relay user equipment sends the IP address information of the remote user equipment to the proximity service server.

Specifically, the IP address information may be the fourth version of the Internet Protocol (English: Internet Protocol Version 4, IPv4) address and port number, or the sixth version of the Internet Protocol (English: Internet Protocol Version 6, referred to as: IPv6) ). The IP address information is assigned by the relay user equipment to the remote user equipment.

207. The proximity service server sends the IP address information of the remote user equipment to the interception center device or sends the IP address information of the remote user equipment to the remote user equipment. Following the network side device of the user equipment.

It can be understood that the proximity service server may not need to send the IP address information of the remote user equipment to the monitoring center device or the network side device of the relay user equipment immediately after determining to listen to the remote user equipment. The short-distance service server may periodically send the monitored IP address information to the monitoring center device or the network side device of the relay user device, or may be in the case of determining to listen to the remote user device. After receiving the indication for requesting the reported IP address information, the monitoring center device sends the monitored permanent identification information to the monitoring center device or the network side device of the relay user equipment. Therefore the proximity service server The IP address information of the remote user equipment may also be saved to send the permanent identification information of the remote user equipment to the monitoring center device or the network side device of the relay user equipment when determining the need.

Further, the short-distance service server may further receive the short-range service related information sent by the relay user equipment, and send the short-range service related information to the interception center device; or the short-distance service server may receive the short-distance service The related information is saved, and the near-distance service related information is sent to the monitoring center device. The information about the short-distance service access includes: an access time of the remote user equipment to access the relay user equipment, identifier information of the relay user equipment, a network identifier and an indication of the current service network of the relay user equipment. Information and the like, wherein the identification information of the relay user equipment may include at least one of the following: an IMEI, an IMSI, an MSISDN, a TMSI, a proximity service discovery user equipment identifier, and a temporary identifier, where the indication information is used to indicate the remote user The device accesses the network through the relay user equipment. In this way, the proximity service server and/or the interception center device can sense the proximity service related information to determine the network side device of the relay user equipment, so as to send the IP address information to the network side of the relay user equipment. device. After receiving the short-range service related information, the monitoring center device may use the near-distance service related information to perform subsequent analysis on the object to be monitored.

If the proximity service server sends the IP address information of the remote user equipment to the interception center device, step 208 is further included.

208. The interception center device sends the IP address information of the remote user equipment to the network side device of the relay user equipment.

After obtaining the IP address of the remote user equipment, the monitoring center device can determine whether the communication content of the remote user equipment is needed. If it is determined that the communication content of the remote user equipment needs to be monitored, the IP address information of the remote user equipment is sent to the network side device of the relay user equipment. If it is determined that the communication content of the remote user equipment is not required to be monitored, the IP address information of the remote user equipment may not be sent to the network side device of the relay user equipment.

209. After receiving the IP address information of the remote user equipment from the short-distance service server or the interception center device, the network side device of the relay user equipment may use the IP address information of the remote user equipment to identify The packet of the remote user equipment is sent out.

After identifying the packet of the remote user equipment, the network side device of the relay user equipment may send the packet of the remote user equipment to the monitoring center device according to a preset rule, or Receiving a finger sent by the monitoring center device for requesting reporting of the received message The packet of the remote user equipment is sent to the monitoring center device. The preset rule may be that the identified message of the remote user equipment is sent to the monitoring center device according to a specific time interval. The predetermined rule may also be to send specific content (eg, including a specific phrase, word in the communication content) to the monitoring center device. In this way, the interception center device can determine not only the time when the object corresponding to the permanent identifier information is accessed to the network, but also the time when the object corresponding to the permanent identifier information is connected to the network, and the communication content of the object corresponding to the permanent identifier information.

Optionally, the relay user equipment may only report the IP address information of the remote user equipment to the short-distance service server, or may report the short-distance service related information only to the short-distance service server. That is, only step 210 or step 211 can be performed. Of course, the relay user equipment can simultaneously report the IP address information of the remote user equipment and the close-range service related information.

210. The relay user equipment sends the IP address information of the remote user equipment to the proximity service server.

212. The interception center device determines to report the event type indication and sends the report event type indication to the proximity service server, where the report event type indication is used to indicate an event type reported by the server to the interception center device, and the event type includes monitoring. At least one of identification information of the object, IP address information of the interception object, and the proximity service related information.

It can be understood by those skilled in the art that the interception center device can not only monitor the user equipment through the short-distance service server, but also monitor the user equipment through other servers or network devices. Therefore, the reported event type indication can be sent to all servers that can listen to the user equipment. Obviously, these servers include the proximity service server.

For example, for the interception object whose permanent identification information is A1, the interception center device may instruct the proximity service server to report only the permanent identification information of the interception object; for the interception object whose permanent identification information is A2, the interception center device may Instructing the proximity service server to report only the IP address information of the interception object; for the interception object whose permanent identification information is A3, the interception center device may instruct the proximity service server to report the permanent identification information of the interception object and the interception object IP address information. It can be understood that the interception object referred to in step 211 may be a remote user equipment in the D2D relay service, and may be a user equipment that needs to be monitored during the normal monitoring process.

213. When it is determined that the remote user equipment is monitored, the short-distance service server determines, according to the reporting type indication, the permanent identification information of the remote user equipment and the IP address of the remote user equipment to be sent to the monitoring center device. At least one of information and the near-field business related information.

Similar to the step 205 and the step 207, the proximity service server may also save the permanent identification information of the remote user equipment, the IP address information of the remote user equipment, and the close distance after determining to listen to the remote user equipment. The service-related information, or the type of the event that needs to be reported, can be saved according to the report type indication.

At the same time, it can be understood that, if only step 210 is performed, the information sent by the short-range service server to the interception center device may be permanent identification information of the remote user equipment and/or IP address information of the remote user equipment. . If only step 211 is performed, the information sent by the proximity service server to the interception center device may be permanent identification information of the remote user equipment and the proximity service related information. If both the step 210 and the step 211 are performed, the information that the short-distance service server can send to the interception center device may include any one or more of the following: permanent identification information of the remote user equipment, the remote user IP address information of the device and related information of the proximity service.

214. The interception center device sends the IP address information of the remote user equipment to the network side device of the relay user equipment.

215. After receiving the IP address information of the remote user equipment from the interception center device, the network side device of the relay user equipment may identify the remote user equipment by using the IP address information of the remote user equipment. Message.

After identifying the packet of the remote user equipment, the network side device of the relay user equipment may send the packet of the remote user equipment to the monitoring center device according to a preset rule, or Receiving a finger sent by the monitoring center device for requesting reporting of the received message The packet of the remote user equipment is sent to the monitoring center device. And sending the packet of the remote user equipment to the monitoring center device according to a preset rule. Step 214 is similar to step 209 except that the network side device of the relay user equipment receives the IP address information of the remote user equipment only from the monitoring center device.

If the remote user equipment and the relay user equipment belong to the same home network, the short-distance service server in FIG. 3 is a short-distance service server in the home network. If the remote user equipment and the relay user equipment belong to different home networks, the short-distance service server referred to in FIG. 3 is the first close-range service server.

The second type of remote user equipment is located within the network coverage. In this case, although the second remote user equipment needs to communicate with the network through the relay user equipment, the second remote user equipment is still capable of communicating with the proximity service server of the home network.

302. The proximity service server acquires at least one of an IMSI, an IMEI, and an MSISDN of the second type of remote user equipment.

The specific steps of step 302 are completely consistent with step 203, and need not be described here.

Similarly, for convenience of description, the following uses the permanent identification information to refer to the first identification information or the second identification information. Specifically, if the first identifier information in step 201 is any one of an IMSI, an IMEI, and an MSISDN, the permanent identifier information is the first identifier. If the first identification information in step 201 is any one of a TMSI, a short-distance service discovery user equipment identifier, and a temporary identifier, the permanent identifier information is the second identifier information in step 203. The second identification information in step 302 is consistent with the second identification information in step 203.
