judging whether there are idle resources currently to meet the quality of service requirements of the device-to-device user;

if there are, allocating the idle resources to the device-to-device user.

3. The method of claim 1, wherein,

said allocating resources that meet quality of service requirements of the device-to-device user and do not cause interference to other cellular users to the device-to-device user, comprises:

broadcasting a detection indicating message to the cellular user and device-to-device user within the service scope;

receiving a detection result sent by the cellular user, and allocate new resources to the device-to-device user according to the detection result and quality of service requirements reported by the device-to-device user;

wherein, the detection result carries a situation of the device-to-device user interfering with the cellular user that is detected by the cellular user according to the received detection indicating message.

4. The method of claim 3, wherein,

the detection indicating message carries information resources used for device-to-device detection that are used to instruct the device-to-device user to broadcast a sounding signal on the information resources, and further used to instruct the cellular user to listen to the sounding signal on the information resources.

5. The method of claim 4, wherein,

the information resources used for the device-to-device detection broadcasted by the base station are downlink resources.

6. The method of claim 4, wherein,

under a situation of users within the service scope all supporting a device-to-device transmission, the information resources used for the device-to-device detection broadcasted by the base station are uplink resources.

7. The method of claim 3, wherein,

the detection indicating message carries a detection indicating identification that is used to instruct the device-to-device user to broadcast a sounding signal on dedicated information resources, and further used to instruct the cellular user to listen to the sounding signal on dedicated information resources.

8. The method of claim 3, wherein,

the detection result also carries a power value of a sounding signal sent by the device-to-device user that is detected by the cellular user.

17. The method of claim 2, wherein,

said allocating resources that meet quality of service requirements of the device-to-device user and do not cause interference to other cellular users to the device-to-device user, comprises:

broadcasting a detection indicating message to the cellular user and device-to-device user within the service scope;

receiving a detection result sent by the cellular user, and allocate new resources to the device-to-device user according to the detection result and quality of service requirements reported by the device-to-device user;

wherein, the detection result carries a situation of the device-to-device user interfering with the cellular user that is detected by the cellular user according to the received detection indicating message.

18. The method of claim 17, wherein,

the detection indicating message carries information resources used for device-to-device detection that are used to instruct the device-to-device user to broadcast a sounding signal on the information resources, and further used to instruct the cellular user to listen to the sounding signal on the information resources.

9. A base station, comprising:
