Abstract

A communication interception method by a base station, a device and a terminal belonging to device-to-device (D2D) communication includes: receiving a message sent by a device, where the message is used to instruct interception of D2D data of the terminal belonging to the D2D communication; obtaining the D2D data according to the message; and sending the obtained D2D data to the device.

Claims

1. A communication method, comprising:

receiving, by a base station, a first message sent by a first device, wherein the first message is used to instruct the base station to obtain device-to-device (D2D) data of a second device belonging to a D2D communication with a third device;

obtaining, by the base station, wireless resource scheduling information used when the second device belonging to the D2D communication performs the D2D communication, in response to the first message;

obtaining, by the base station, the D2D data of the second device according to the obtained wireless resource scheduling information; and

sending, by the base station, the obtained D2D data of the second device to the first device,

wherein,

when the wireless resource scheduling information is determined by the second device belonging to the D2D communication, the obtaining of wireless resource scheduling information used when the second device belonging to the D2D communication performs the D2D communication comprises,

sending a second message to the second device belonging to the D2D communication, wherein the second message is used to instruct the second device belonging to the D2D communication to report the wireless resource scheduling information; and

obtaining the wireless resource scheduling information reported by the second device belonging to the D2D communication;

or

when the wireless resource scheduling information is allocated by the base station to the second device belonging to the D2D communication, the obtaining of wireless resource scheduling information used when the second device belonging to the D2D communication performs the D2D communication comprises,

obtaining the wireless resource scheduling information allocated by the base station.

2. The method according to claim 1, wherein the first device comprises:

a mobility management entity (MME), a serving gateway SGW, a packet data network gateway PGW, or a fourth device.

3. The method according to claim 1, wherein the obtaining the D2D data according to the first message comprises:

sending a third message to the second device belonging to the D2D communication, wherein the third message is used to trigger the second device belonging to the D2D communication to record the D2D data; and

receiving the D2D data recorded by the second device belonging to D2D.

4. The method according to claim 3, wherein the third message comprises a recording policy used when the second device belonging to the D2D communication records the D2D data, and the recording policy comprises:

a data amount of the D2D data that needs to be recorded, or a T period of time to record the D2D data.

5. A base station, comprising:

a receiver, configured to receive a first message sent by a first device, wherein the first message is used to instruct the base station to obtain device-to-device (D2D) data of a second device belonging to the D2D communication with a third device;

a processor, configured to

obtain wireless resource scheduling information used when the second device belonging to the D2D communication performs the D2D communication, in response to the first message, and

obtain the D2D data of the second device according to the obtained wireless resource scheduling information; and

a sender, configured to send the obtained D2D data of the second device to the first device,

wherein,

when the wireless resource scheduling information is determined by the second device belonging to the D2D communication, the obtainment of wireless resource scheduling information used when the second device belonging to the D2D communication performs the D2D communication comprises,

sending a second message to the second device belonging to the D2D communication, wherein the second message is used to instruct the second device belonging to the D2D communication to report the wireless resource scheduling information; and

obtaining the wireless resource scheduling information reported by the second device belonging to the D2D communication;

or

when the wireless resource scheduling information is allocated by the base station to the second device belonging to the D2D communication, the obtainment of wireless resource scheduling information used when the second device belonging to the D2D communication performs the D2D communication comprises,

obtaining the wireless resource scheduling information allocated by the base station.

6. The base station according to claim 5, wherein the device comprises:

a mobility management entity MME, a serving gateway SGW, a packet data network gateway PGW, or a fourth device.

7. The base station according to claim 5, wherein:

the sender is further configured to send a third message to the second device belonging to D2D communication, wherein the third message is used to trigger the second device belonging to D2D communication to record the D2D data; and

the receiver is further configured to receive the D2D data recorded by the second device belonging to D2D communication.

8. The base station according to claim 7, wherein the third message comprises a recording policy used when the second device belonging to D2D communication records the D2D data, and the recording policy comprises:

a data amount of the D2D data that needs to be recorded, or a T period of time to record the D2D data.
