Description

Monitoring method and related equipment

Technical Field

The embodiment of the invention relates to the technical field of communication, in particular to a monitoring method and related equipment.

Background

End-to-end (D2D) Service, also called Proximity Service (ProSe), refers to that data of a user equipment can be directly transmitted between user equipments without passing through a network.

The D2D relay service means that a ue out of the network coverage or with poor signal quality in the current network communicates with the network through a relay ue. The relay user equipment may communicate directly with the network. A user equipment that needs to communicate with the network through the relay user equipment may be referred to as a remote user equipment.

A monitoring center (LEA) is a department that has a claim to monitor information in communications of user equipment by an operator. The LEA may analyze or take as evidence the information that the operator hears. The device in the LEA responsible for determining and issuing the information of the object to be monitored may be referred to as a monitoring center device. The Information may include Interception Related Information (IRI) and Communication Content (CC), wherein the Interception Related Information refers to signaling messages and network management Information. A network device for listening to a user equipment may be referred to as: a proximity services server (english: ProSe Function). The proximity service server may transmit the monitored information of the user device to the LEA. However, when D2D is applied to relay traffic, the remote ue accesses the network through the relay ue rather than the network side device. In this case, the network device serves the relay user equipment instead of the remote user equipment. Thus, the near field service server cannot listen to the far-end user device.

In a first aspect, an embodiment of the present invention provides a monitoring method, where the method includes: the method comprises the steps that a first near field service server receives a first identification of far-end user equipment sent by relay user equipment, wherein the far-end user equipment is communicated with a network through the relay user equipment; and the first near field service server determines whether to monitor the far-end user equipment or not according to the first identification information of the far-end user equipment. Since the first proximity service server can receive the identification information of the remote user equipment in the D2D relay service, the first proximity service server can listen to the remote user equipment in the D2D relay service.

With reference to the first aspect, in a first possible implementation manner of the first aspect, the first identification information includes at least one of: international Mobile Subscriber Identity (IMSI), International Mobile Equipment Identity (IMEI) and Mobile Station International Integrated Services Digital Network (ISDN) Number (MSISDN); if the first near field service server determines that the monitored object information comprises first identification information of the far-end user equipment, determining to monitor the far-end user equipment, wherein the monitored object information comprises the first identification information of at least one object to be monitored; and if the first near field service server determines that the monitored object information does not comprise the first identification information of the far-end user equipment, determining not to monitor the far-end user equipment.

Detailed Description

The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the embodiments are some, not all, embodiments of the present invention. All other embodiments, which can be obtained by a person skilled in the art without any inventive step based on the embodiments of the present invention, shall fall within the scope of protection 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 (Long Term Evolution, LTE for short) system.

User Equipment (UE), which may also be referred to as a Mobile Terminal (MT), a Mobile User Equipment (ms), or the like, may communicate with one or more core networks via a Radio Access Network (RAN), and may be a Mobile Terminal, such as a Mobile phone (or referred to as a "cellular" phone) and a computer having the Mobile Terminal, such as a portable, pocket, hand-held, computer-embedded, or vehicle-mounted Mobile device.

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

The remote user equipments in the D2D relay 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 remote user equipment which is out of the network coverage. The second type of remote user equipment refers to user equipment which is located in the network coverage area but has poor network quality. The first type of remote user equipment is out of network coverage and therefore cannot communicate with the network. 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 that the quality of the direct communication between the second type of remote user equipment and the network is not good. Therefore, the second type of remote user equipment also needs to communicate with the network through the relay user equipment. As used herein, unless otherwise specified, a remote user equipment includes a first type of remote user equipment and/or a second type of remote user equipment.

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

Fig. 2 is a schematic flow chart of a listening method provided according to an embodiment of the present invention. The interception center device may transmit the interception object information to the first proximity service server or the second proximity service server. The proximity service server in fig. 2 is a proximity service server that receives the information of the listening object.

The relay user equipment receives an access request sent by a far-end user equipment, wherein the access request comprises first identification information of the far-end user equipment.

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

202, the relay user equipment sends the first identification information of the far-end user equipment to the near field service server.

It can be understood that, if the proximity service server is the first proximity service server, the relay user equipment sends the first identification information of the remote user equipment to the proximity service server through the second proximity service server.

203, the proximity services server can obtain at least one of the IMSI, IMEI, and MSISDN of the remote user equipment.

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

Optionally, as another embodiment, in step 201, if the first identification information is at least one of a TMSI, a proximity service discovery user equipment identity, and a temporary identity, the proximity service server may determine, according to a correspondence between the first identification information and second identification information, second identification information of the remote user equipment, where the second identification information is at least one of an IMSI, an IMEI, and an MSISDN. Optionally, as an embodiment, in case that the proximity service server receives the first identification information (i.e. at least one of the TMSI, the proximity service discovery user equipment identity, and the temporary identity), the proximity service server may send a request message to the HSS, where the request message is used to request to acquire a correspondence between the first identification information and the second identification information (i.e. at least one of the IMSI, the IMEI, and the MSISDN). The HSS may send the correspondence between the first identification information and the second identification information to the proximity service server, upon receiving the request message. Optionally, as another embodiment, the proximity service server may store a ProSe context, where the ProSe context includes a correspondence between the first identification information of the remote user equipment and the second identification information of the remote user equipment. In this way, the proximity service server can determine the second identification information of the remote user equipment. Specifically, the far-end user device may have established a connection with the proximity service server once and sent the first identification information of the far-end user device to the proximity service server. In this case, the proximity service server may request the HSS to acquire a correspondence between the first identification information and the second identification information, so as to determine the second identification 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 identification information of the remote user equipment and the second identification information of the remote user equipment. It can be understood that, if the proximity service server is the second proximity service server, the proximity service server may obtain the corresponding relationship between the first identification information and the second identification information through the first proximity service server. The manner of acquiring the corresponding relationship between the first identification information and the second identification information by the first proximity service server is the same as the manner described above.

For convenience of description, the permanent identification information is used hereinafter to refer to the above-mentioned first identification information or second identification information. Specifically, if the first identification information is any one of the IMSI, IMEI, and MSISDN in step 201, the permanent identification information is the first identification information. If the first identification information in step 201 is any one of the TMSI, the proximity service discovery user equipment identity, and the temporary identity, the permanent identification information is the second identification information in step 203.

If the first identification information is TMSI, the short-distance service discovery user equipment identification and the temporary identification, the IMEI, the IMSI and the MSISDN of the far-end user equipment cannot be transmitted among the far-end user equipment, the relay user equipment and the short-distance service server. Therefore, the IMEI, the IMSI and the MSISDN of the remote user equipment can be prevented from being monitored by other people, and potential safety hazards caused by leakage of the IMEI, the IMSI and the MSISDN of the remote user equipment are avoided.

The proximity services server may determine whether to listen to the remote user device based on the permanent identification information of the remote user device 204.

Specifically, the proximity service server may determine whether to include the permanent identification information of the remote user equipment in the interception object information, where the interception object information includes the permanent identification information of at least one object to be intercepted. If the short-distance service server determines that the monitored object information comprises the permanent identification information of the far-end user equipment, determining to monitor the far-end user equipment; and if the short-distance service server determines that the monitored object information does not comprise the permanent identification information of the far-end user equipment, determining not to monitor the far-end user equipment. It can be understood that the proximity service server needs to implement obtaining the information of the listening object. The interception target information is acquired by the proximity service server from the interception center device. The interception center device may determine in advance the permanent identification information of the object to be intercepted, and send the permanent identification information of the object to be intercepted to the proximity service servers in the respective PLMNs.

Those skilled in the art will understand that there is a correspondence between the IMEI, IMSI and MSISDN. The proximity service server may obtain other identifiers when obtaining any one identifier of the IMEI, the IMSI, and the MSISDN. For example, if the first identification information acquired by the proximity service server from the relay user equipment is an IMEI and the permanent identification information in the monitored object information is an IMSI, the proximity service server may determine the IMSI of the remote user equipment according to a correspondence between the IMSI and the IMEI, and determine whether the monitored object information includes the IMSI of the remote user equipment. In other words, the specific identifier of the permanent identifier in the monitored object information may not be completely the same as the specific identifier in the permanent identifier acquired by the proximity service server, but the proximity service server can determine the specific identifier that can be used for matching the permanent identifier in the monitored object information according to the correspondence between the IMEI, the IMSI, and the MSISDN.

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

205, in case of determining to listen to the remote user equipment, the proximity service server sends the permanent identification information of the remote user equipment to the listening center device.

It will be appreciated that the proximity services server may not need to send the permanent identification information of the remote user device to the listening center device immediately after determining to listen to the remote user device. The proximity service server may periodically send the monitored permanent identification information to the monitoring center device under the condition that monitoring of the remote user device is determined, or may send the monitored permanent identification information to the monitoring center device after receiving an instruction for requesting reporting of the monitored permanent identification information sent by the monitoring center device. The proximity service server may also store the permanent identification information of the remote user device so that the permanent identification information of the remote user device is sent to the listening center device when it is determined to be needed. After receiving the permanent identification information sent by the proximity service server, the monitoring center device may determine that an object corresponding to the permanent identification information accesses the network and a time when the object corresponding to the permanent identification information accesses the network. After determining that the object corresponding to the permanent identification information is accessed to the network, the interception center device may perform a series of operations as needed, for example, may determine the location information of the object corresponding to the permanent identification information.

206, the relay user equipment sends the IP address information of the remote user equipment to the short-range service server.

Specifically, the IP address information may be an Internet protocol Version four (english: Internet protocol Version 4, abbreviated as IPv4) address and port number, or may be an Internet protocol Version six (english: Internet protocol Version 6, abbreviated as IPv 6). The IP address information is assigned to the remote user equipment by the relay user equipment.

207, the proximity service server sends the IP address information of the remote user equipment to the monitoring center device or sends the IP address information of the remote user equipment to the network side device of the relay user equipment, if it is determined to monitor the remote 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 interception center device or the network side device of the relay user equipment immediately after determining to intercept the remote user equipment. The proximity 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 under the condition that monitoring of the remote user device is determined, or may send the monitored permanent identification information to the monitoring center device or the network side device of the relay user device after receiving an instruction sent by the monitoring center device for requesting reporting of the monitored IP address information. Therefore, the near field service server can also store the IP address information of the remote user equipment, so as to send the permanent identification information of the remote user equipment to the monitoring center equipment or the network side equipment of the relay user equipment when determining the need.

Further, the short-distance service server can also receive the short-distance service related information sent by the relay user equipment and send the short-distance service related information to the monitoring center equipment; or, the proximity service server may receive the proximity service related information, store the proximity service related information, and send the proximity service related information to the monitoring center device. The information related to the access proximity service comprises: the access time of the remote user equipment accessing the relay user equipment, the identification information of the relay user equipment, the network identification and indication information of the current service network of the relay user equipment, and the like, wherein the identification information of the relay user equipment may include at least one of the following: IMEI, IMSI, MSISDN, TMSI, short-range service discovery user equipment identification and temporary identification, the indication information is used for indicating the far-end user equipment to access the network through the relay user equipment. In this way, the proximity service server and/or the interception center device may feel the proximity service related information to determine the network side device of the relay user device, so as to send the IP address information to the network side device of the relay user device. After receiving the relevant information of the short-distance service, the monitoring center equipment can utilize the relevant information of the short-distance service to perform subsequent analysis on the object to be monitored.

If the short-distance service server sends the IP address information of the remote user equipment to the monitoring center equipment, step 208 is also included.

208, the interception center device sends the IP address information of the remote ue to the network side device of the relay ue.

After acquiring the IP address of the remote user equipment, the monitoring center equipment may determine whether the communication content of the remote user equipment is needed. And if the communication content of the remote user equipment needs to be monitored is determined, the IP address information of the remote user equipment is sent to the network side equipment of the relay user equipment. If it is determined that monitoring of the communication content of the remote user equipment is not required, 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 the network side device of the relay user device receives the IP address information of the remote user device from the proximity service server or the monitoring center device, the network side device may identify the packet of the remote user device by using the IP address information of the remote user device.

After the network side device of the relay user equipment recognizes the message of the remote user equipment, the network side device may send the message of the remote user equipment to the monitoring center device according to a preset rule, or may send the message of the remote user equipment to the monitoring center device after receiving an instruction for requesting to report the monitored message sent by the monitoring center device. The preset rule may be to send the identified message of the remote ue to the interception center device at a specific time interval. The preset rule may also be to send specific content (for example, the communication content includes a specific phrase or word) to the monitoring center device. Thus, the interception center device can not only determine the access time of the object corresponding to the permanent identification information to the network and the access time of the object corresponding to the permanent identification information to the network, but also obtain the communication content of the object corresponding to the permanent identification information.

Optionally, the relay user equipment may only report the IP address information of the remote user equipment to the proximity service server, or may only report the relevant information of the proximity service to the proximity service server. That is, only step 210 or step 211 may be performed. Of course, the relay user equipment may also report the IP address information of the remote user equipment and the relevant information of the proximity service at the same time.

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

Step 210 is identical to step 206 and need not be described in detail herein.

211, the proximity service server may further receive proximity service related information sent by the relay user equipment.

The information related to the access proximity service comprises: the access time of the remote user equipment accessing the relay user equipment, the identification information of the relay user equipment, the network identification and indication information of the current service network of the relay user equipment, and the like, wherein the identification information of the relay user equipment may include at least one of the following: IMEI, IMSI, MSISDN, TMSI, short-range service discovery user equipment identification and temporary identification, the indication information is used for indicating the far-end user equipment to access the network through the relay user equipment. In this way, the proximity service server and/or the interception center device may feel the proximity service related information to determine the network side device of the relay user device, so as to send the IP address information to the network side device of the relay user device.

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

Those skilled in the art can understand that the interception center device can not only intercept the user equipment through the proximity service server, but also intercept the user equipment through other servers or network devices. Therefore, the reporting event type indication can be sent to all servers that can monitor the ue. Obviously, the proximity service server is included in the servers.

For example, for the monitored object with permanent identification information of a1, the monitoring center device may instruct the proximity service server to report only the permanent identification information of the monitored object; for the monitored object with permanent identification information of a2, the monitoring center device may instruct the proximity service server to report only the IP address information of the monitored object; for the monitored object with permanent identification information of a3, the monitoring center device may instruct the proximity service server to report the permanent identification information of the monitored object and the IP address information of the monitored object. It is to be understood that the listening object referred to in step 211 may be a remote user equipment in the D2D relay service, or may be a user equipment that needs to listen in the conventional listening process.

213, in case of determining to monitor the remote user equipment, the proximity service server determines to send at least one of the permanent identification information of the remote user equipment, the IP address information of the remote user equipment, and the proximity service related information to the monitoring center equipment according to the report type indication.

Similar to step 205 and step 207, the proximity service server may also store the permanent identification information of the remote user equipment, the IP address information of the remote user equipment, and the proximity service related information after determining to monitor the remote user equipment, or may only store the event type to be reported according to the reporting type indication.

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

214, the interception center device sends the IP address information of the remote ue to the network side device of the relay ue.

215, after the network side device of the relay ue receives the IP address information of the remote ue from the monitoring center device, the network side device may identify the packet of the remote ue by using the IP address information of the remote ue.

After the network side device of the relay user equipment recognizes the message of the remote user equipment, the network side device may send the message of the remote user equipment to the monitoring center device according to a preset rule, or may send the message of the remote user equipment to the monitoring center device after receiving an instruction for requesting to report the monitored message sent by the monitoring center device. And sending the message of the remote user equipment to the monitoring center equipment according to a preset rule. Step 214 is similar to step 209, except that the network side device of the relay ue only receives the IP address information of the remote ue from the listener equipment.

If the remote user equipment and the relay user equipment belong to the same home network, the proximity service server in fig. 3 is a proximity service server in the home network. If the far-end ue and the relay ue belong to different home networks, the proximity service server in fig. 3 is referred to as the first proximity service server.

301, a second type of remote user equipment sends, to a proximity service server, first identification information of the second type of remote user equipment and relay-related information, where the relay-related information includes identification information of the relay user equipment, time for the second type of remote user equipment to access or disconnect the relay user equipment, and communication content of the second type of remote user equipment, the second type of remote user equipment is located within a network coverage and communicates with a network through the relay user equipment, and the identification information includes at least one of: IMEI, IMSI, MSISDN, TMSI, proximity service discovery user equipment identity and temporary identity.

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

302, the proximity service server obtains at least one of IMSI, IMEI and 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 herein.

Also, for convenience of description, the permanent identification information is used hereinafter to refer to the above-described first identification information or second identification information. Specifically, if the first identification information is any one of the IMSI, IMEI, and MSISDN in step 201, the permanent identification information is that the first identifier wants to be contacted. If the first identification information in step 201 is any one of the TMSI, the proximity service discovery user equipment identity, and the temporary identity, the permanent identification information is the second identification information in step 203. The second identification information in step 302 coincides with the second identification information in step 203.

303 the proximity service server may determine whether to listen to the second type of remote user equipment based on the permanent identification information of the second type of remote user equipment.

304, in case of determining to listen to the second type of remote user equipment, the proximity service server sends the permanent identification information of the second type of remote user equipment and the relay-related information to the listening center device.

Steps 303 and 304 are similar to steps 204 and 205. The difference is that the information reported by the proximity service server includes the permanent identification information of the second type of remote user equipment and the relay related information of the second type of remote user equipment. Therefore, the detailed description is not necessary here.

In the embodiments of fig. 2 to 3, the IP address information of the remote user equipment may be transmitted to the proximity service server simultaneously with the first identification information of the remote user equipment. The IP address information of the remote user device may also be sent to the proximity services server in other circumstances. For example, if the proximity service server determines that the remote user equipment is an object to be monitored according to the permanent identification information of the remote user equipment, the proximity service server may request the relay user equipment to report the IP address information of the remote user equipment. For another example, after receiving the permanent identification information of the remote user equipment reported by the proximity service server, the monitoring center device may request the proximity service server to report the IP address information of the remote user equipment if it is determined that the communication content of the remote user equipment needs to be monitored. In this case, the proximity service server may request the relay user equipment to report the IP address information of the remote user equipment.

Further, the network side device of the relay user equipment comprises one or more of the following: the Home device Server (HSS) of the relay user equipment Home Network, the Mobility Management Element (MME) of the relay user equipment service Network, the Serving Gateway (SGW) of the relay user equipment service Network, the Public Data Network (PDN) Gateway (PGW) of the relay user equipment service Network, and the PGW of the relay user equipment Home Network. The service network refers to a network to which the user equipment is currently registered.
