S110 monitors the device discovery signal that other subscriber equipmenies send on this broadcast resource on the broadcast resource of first user equipment in the device discovery resource.
S120 forwards all or part of device discovery signal in the device discovery signal that listens on the relay resource of this first user equipment in the device discovery resource.
When a certain subscriber equipment (being other subscriber equipmenies described in method 100) when a certain service need to be provided, device discovery signal that can transmission itself on broadcast resource, wherein, the sign (Identification, ID) that this device discovery signal can comprise this subscriber equipment with and the COS that can provide; First user equipment can be monitored the device discovery signal that is sent on broadcast resource by other subscriber equipmenies on broadcast resource, then, this first user equipment can be relayed all or part of device discovery signal in forwarding the device discovery signal that listens to relaying resource, to increase the distance of device discovery.
In embodiments of the present invention, as shown in Figure 2, the method 100 can also comprise:
S130 when first user equipment can provide a certain service, sends the device discovery signal of self on broadcast resource.
In embodiments of the present invention, broadcast resource and relay resource can be found resource by component devices.Wherein, this device discovery resource can be the proprietary frequency spectrum resource for D2D communication device discovery.
The division of device discovery resource can be as shown in Figure 3, and wherein the x axle is the time, and the y axle represents frequency.In Fig. 3, a little square represents a resource particle (Resource Element is called for short RE).Each equipment can take the transmission that one or more RE carry out the device discovery signal, for example the dash area shown in Fig. 3.
In embodiments of the present invention, first user equipment can periodically be monitored the device discovery signal on broadcast resource, also can begin to monitor the device discovery signal on broadcast resource when a certain service of needs, it can be also the device discovery signal that begins to monitor on broadcast resource after subscriber equipment starts, can be also that (after for example, bluetooth is opened) begins to monitor the device discovery signal on broadcast resource after a certain function is opened.
In embodiments of the present invention, this first user equipment can be relayed at this and be forwarded the signal strength signal intensity that listens on resource less than the device discovery signal of predetermined threshold.In embodiments of the present invention, the predetermined threshold of signal strength signal intensity can be set according to the density of D2D subscriber equipment, and wherein, it is lower that the predetermined threshold of higher this signal strength signal intensity of the density of subscriber equipment can arrange.Wherein, the density of this subscriber equipment can be determined according to the utilance of device discovery resource.The threshold value that should be understood that this signal strength signal intensity also can be set according to other factors, and the present invention does not limit this.

S303, subscriber equipment is measured the signal strength signal intensity of the device discovery signal of the broadcast resource that listens to, and judge whether that signal strength signal intensity is less than the device discovery signal of predetermined threshold, if do not have, can finish to monitor, perhaps can continue to monitor own needed device discovery signal to filter out own needed more excellent device discovery signal, if having carry out S304.
S304, subscriber equipment after obtaining the device discovery signal of N signal strength signal intensity less than predetermined threshold, measurement that can stop signal intensity.Also can continue to monitor own needed device discovery signal to filter out own needed more excellent device discovery signal, certainly, if found own needed device discovery signal, can directly finish to monitor.
S305, subscriber equipment is being relayed the random top n device discovery signal of selecting resource forwarding to obtain on resource, wherein, can carry out forwarding obtaining whole top n device discovery signals, can be also to forward while finding and do not wait until that obtaining whole N device discovery signals forwards again again.
Fig. 6 is the indicative flowchart according to the information transferring method 400 of the embodiment of the present invention.As shown in Figure 6, this information transferring method 400 comprises:
S401, subscriber equipment is opened monitor function.
At first S402, subscriber equipment monitor the device discovery signal on broadcast resource.
S403, subscriber equipment is measured the signal strength signal intensity that receives on broadcast resource, and judges whether to exist signal strength signal intensity less than the device discovery signal of predetermined threshold, if exist carry out S404.
S404, subscriber equipment obtain the top n signal strength signal intensity and do not surpass the device discovery signal of threshold value, the measurement of stop signal intensity.
S405, subscriber equipment are random on the relay resource selects the top n signal strength signal intensity that resource is relayed and listened to surpass the device discovery signal of predetermined threshold.
S406, whether subscriber equipment judgement received device discovery signal on broadcast resource has needed device discovery signal, monitor if having finish, if not carry out S407, wherein, the present invention does not limit the execution sequence of S406, as long as carry out after S402, for example, with S403, S404 or S405 executed in parallel.For example, at S403, if subscriber equipment determines not have signal strength signal intensity less than the device discovery signal of predetermined threshold, carry out S406.
S407 monitors and relays the device discovery signal that is forwarded on resource.
S408 selects needed device discovery signal, finishes to monitor.
Should be understood that above method is specific embodiments of the invention, the embodiment of the present invention can also have multiple implementation.for example, for method 400, can listening period be set for broadcast resource, for example, listening period for broadcast resource is set to 1ms, if after monitoring 1ms for broadcast resource, N signal strength signal intensity do not detected yet and do not detect needed device discovery signal over the device discovery signal of threshold value yet, can stop the monitoring of broadcast resource is directly monitored relaying resource, also can and relay resource and monitor simultaneously until listen to N signal strength signal intensity on broadcast resource and just finish monitoring to broadcast resource over the device discovery signal of predetermined threshold broadcast resource.
Will also be understood that, in various embodiment of the present invention, the size of the sequence number of above-mentioned each process does not also mean that the priority of execution sequence, and the execution sequence of each process should determine with its function and internal logic, and should not consist of any restriction to the implementation process of the embodiment of the present invention.
