Method, apparatus, and system for measurement for divice-to-divice communication

A method for measurement for D2D communication, comprising:

• receiving, by a wireless network management entity, a consulting message for D2D communication between terminals that is sent directly or forwarded by an access point, wherein the consulting message is used to request the wireless network management entity to calculate a performance evaluation parameter for D2D communication between the terminals, wherein the performance evaluation parameter for D2D communication between the terminals is used to evaluate feasibility of measurement for D2D communication between the terminals;
• calculating, according to received device information of the terminals, the performance evaluation parameter for D2D communication between the terminals, wherein the device information comprises capability information and location information of the terminals;
• and
• sending, to the access point, the performance evaluation parameter for D2D communication between the terminals.

An access point, comprising:

• a sending unit, configured to send directly or forward, to a wireless network management entity, a consulting message for D2D communication between terminals, wherein the consulting message is used to request the wireless network management entity to query a performance evaluation parameter for D2D communication between the terminals, wherein the performance evaluation parameter for D2D communication between the terminals is used to evaluate feasibility of measurement for D2D communication between the terminals;
• a receiving unit, configured to receive a performance evaluation parameter for D2D communication between the terminals that is sent by the wireless network management entity;
• and
• a determining unit, configured to determine, according to the performance evaluation parameter for D2D communication between the terminals that is received by the receiving unit, to perform the measurement for D2D communication between the terminals, and perform measurement configuration for the terminals, wherein
• the determining unit is further configured to determine, according to a result of the measurement for D2D communication between the terminals, to perform D2D communication between the terminals.

A wireless network management entity, comprising:

• an information receiving unit, configured to receive a consulting message for D2D communication between terminals that is sent directly or forwarded by an access point, wherein the consulting message is used to request the wireless network management entity to query a performance evaluation parameter for D2D communication between the terminals, wherein the performance evaluation parameter for D2D communication between the terminals is used to evaluate feasibility of measurement for D2D communication between the terminals;
• a calculating unit, configured to calculate, according to device information of the terminals received by the information receiving unit, the performance evaluation parameter for D2D communication between the terminals, wherein the device information comprises capability information and location information of the terminals;
• and
• a parameter sending unit, configured to send, to the access point, the performance evaluation parameter for D2D communication between the terminals obtained by the calculating unit by calculation.
