s40, the monitoring D2D terminal judges whether the control access grade accords with the control access strategy corresponding to the monitoring D2D terminal according to the retrieval result, if yes, the step S50 is carried out, and if not, the step S60 is carried out;
s50, monitoring that the D2D terminal allows the D2D direct connection communication to be initiated;
and S60, the monitoring D2D terminal prohibits initiating D2D direct communication.
Specifically, a field identifier of a service type is set in a discovery signal of D2D, when a D2D terminal initiating a service request makes a service request, a current service type may be added to the discovery signal of D2D, a monitoring D2D terminal monitors that the discovery signal can resolve the service type identifier, determines a specific D2D service type according to the service type identifier, and records time and geographic position at that time, and then sets and retrieves, according to a D2D control access level, whether a control access level to which the service type belongs meets a D2D control access policy requirement of the terminal, if the requirement is met, the initiation of D2D direct connection communication is allowed, otherwise, the direct connection communication is rejected. Therefore, the D2D direct connection communication can be carried out in a personalized way in different service types, different time periods and different places, the user experience is improved, and the phenomenon that the notification or the advertisement is pushed to the user without limit to cause interference is avoided.

The control level table comprises a time period, a geographical position, a service type, a control access level and a control access strategy, and is set by a user in a self-defined way or a terminal can provide default settings, wherein the geographical position is recorded according to longitude and latitude, but a specific threshold range of the geographical position is monitored during actual calculation; the service type distance is described as follows, the specific service type and the identification field can select standardized content, and the basis for controlling the access level setting is determined according to the safety, applicability and important characteristics of each service type in the corresponding time period and the corresponding geographic position. If the emergency service belongs to the special emergency service, the access grade is highest and is set as 1; office business is more applicable and important for the company, so the security level is higher and is set as 2; but for at home, the applicable and important level of office business may be reduced, such as setting the security level at 5 at home; and so on. Wherein the smaller the value, the higher the control access level. Wherein the control access policy is settable by a user depending on security and applicable and important characteristics at the corresponding time period and the corresponding geographical location.
