Description
Technical field
The present invention relates to communication technical field, the implementation method that the equipment straight-through (Device-to-Device is called for short D2D) being specifically related to control PCRF charging in a kind of long evolving system communicates.
Background technology
At present, the D2D communication based on cellular system received extensive concern in recent years, and the D2D communication technology has the following advantages: because data do not need the switching by base station, but direct transfer between user, and D2D technology decreases the burden of base station process communication; Can select with other user's multiplexed resource to improve the utilance of resource; The both sides carrying out D2D communication, usually apart from very near, therefore save transmitted power etc.But, under current communication system, charging process is completed by following module: "Policy and Charging Rules Function module (PolicyandChargingRuleFunction, referred to as PCRF) user property memory (SubscriptionProfileRepository, referred to as SPR) download or configured the billing logic obtained user by operator; Applied function module (ApplicationFunction, referred to as AF), strategy and charge execution function module (PolicyandChargingEnforcementFunction, referred to as PCEF) provide the data of the input required for charging policy.PCRF obtains the metrical information of business datum from AF, PCEF, assigns performing billing function to PCEF according to billing logic generation charging policy.
But in D2D communication process, data do not need to be transmitted by base station, but direct transfer between users, in traditional cellular communication charge mode, base station cannot monitor the flow of D2D communication data, and PCRF cannot be made to generate charging policy and carry out charging to D2D communication.
Summary of the invention
The object of the invention is to for the deficiencies in the prior art, the D2D Realization Method of Communication of a kind of control PCRF charging is proposed, reported the time started of setting up communication to PCRF by D2D user, end time and data traffic, make PCRF generate charging policy, ensure to use business to charge normally.
For achieving the above object, the technical solution used in the present invention is as follows:
For controlling the method for charging in D2D communication, comprise base station, and the first user of at least one pair of be in same community and carry out the user that D2D communicates with described first user, said method comprising the steps of:
(1) in described same community, described first user periodically sends detectable signal to neighbouring user, sounding channel quality, wherein, described base station receives described detectable signal by the signaling user controlled near described first user, comprises the ID of described first user in signaling;
(2) user that the channel quality and between described first user is greater than threshold value X feeds back itself ID to described first user;
(3) ID of its ID and described feedback arranges as list and is sent to PCRF by described first user, the list received is forwarded to SPR by described PCRF, retain allowing the ID of the user carrying out D2D communication and maintain the list that remaining ID forms, this table is sent to PCRF again;
Wherein SPR possesses the function detecting user and whether allow D2D to serve;
(4), when described first user initiates D2D communication connection request to described nearby users, message is sent to PCRF;
(5) when D2D communication connection disconnects, described first user sends carrying to described PCRF, and described carrying parsing, after receiving described carrying, is issued PCEF by described PCRF, and described PCEF carries out charging according to PCC charging regulation or time.
It should be noted that, described threshold value X can set up with described first user the minimum value that D2D communicates to connect, and wherein, when described channel quality is less than described threshold value X, then can not set up D2D communication connection; When described channel quality is greater than described threshold value X, then can set up D2D communication connection.
It should be noted that, described first user ID is included in described message, and the nearby users of its ID is fed back to described first user, when described nearby users ID in lists, described PCRF sends carrying to first user, and the data traffic between itself and described nearby users monitored by described first user log-on data traffic monitoring stream device simultaneously.
It should be noted that, described carrying includes described first user and nearby users and sets up the time point that D2D communicates to connect, the time point of end, and the data traffic information between described first user and nearby users.
It should be noted that, when described nearby users ID not in lists, then notify that cellular communication is carried out in described base station.
Beneficial effect of the present invention is:
Whether can detect user in SPR allows D2D to serve (may relate to user and whether pay the expense of opening correlation function to operator), even if the user of D2D oneself ID can not have been sent out in Access Network mistake, and finally also can by filtering; Solve the billing issues of D2D communication, ensure that operator can regular fee.
