The Fig. 1 of take below describes a kind of method for discovering equipment that the embodiment of the present invention one provides in detail as example, the flow chart of a kind of method for discovering equipment that Fig. 1 provides for the embodiment of the present invention one.The executive agent of this method for discovering equipment is base station.As shown in Figure 1, this method for discovering equipment comprises the following steps:

Step S101, obtains the facility information of first user equipment.

Wherein, this first user equipment can be specially the subscriber equipment with D2D communication function.Facility information can comprise: the D2D communication capacity of first user equipment, the D2D identifier (Identification, ID) of first user equipment etc.

Alternatively, the facility information that base station sends by reception first user equipment is to obtain facility information.

Concrete, first user equipment can be by Event triggered to base station transmitting apparatus information.For example, during first user device power-up in base station range, or when first user equipment switches from other community or is linked at random this base station, or the point-to-point traffic carrying capacity of first user equipment in base station range is when larger, and this first user equipment is to base station transmitting apparatus information.In addition, first user equipment also can be initiatively to base station transmitting apparatus information.For example, the first user equipment in base station range is after start, and user is not when having choice for use D2D function, and first user equipment does not need to base station transmitting apparatus information, when user's choice for use D2D function, then to base station transmitting apparatus information.Or the first user equipment in base station range is after start or use D2D function, whether inquiry user adds this first user equipment in the user device list of base station, when user adheres to, to base station, send the facility information of this first user equipment.Or the first user equipment in base station range sends the request that adds user device list to base station, when obtaining after base station is agreed to, to base station, send the facility information of this first user equipment.

Alternatively, base station receives the user device list that neighbor base station sends, and the user device list sending, obtains facility information from neighbor base station.

Because first user equipment can switch between a plurality of communities, for making base station can obtain the facility information of cutting the first user equipment in its place base station range from adjacent area the very first time, base station can be by receiving the user device list of neighbor base station, to obtain the facility information of the first user equipment in neighbor base station coverage at present.

Step S102, is added to user device list by the facility information getting.

Concrete, base station can directly be added into facility information in user device list after getting facility information; Also the facility information getting can be carried out to buffer memory, when base station determines that the traffic carrying capacity of the first user equipment that its facility information getting is corresponding surpasses threshold value and/or communication pattern and changes and/or receive corresponding first user equipment sends add user device list acknowledge message or add user device list request, then the facility information of this first user equipment is added in user device list.

Step S103, the second subscriber equipment in base station range sends user device list, in order to the second subscriber equipment, according to user device list, finds first user equipment.

Wherein, this second subscriber equipment can be specially the subscriber equipment with D2D communication function.

Concrete, any the second subscriber equipment in base station range sends user device list.Or, to the second subscriber equipment in base station range and that user device list comprises, send user device list.Or, base station is before sending user device list, can receive the user device list request of obtaining that the second subscriber equipment sends, then the second subscriber equipment that only obtains user device list request to transmission sends user device list, or to comprising, sends one group of second subscriber equipment of the second subscriber equipment that obtains user device list request or any the second subscriber equipment transmission user device list in base station range after receiving the user device list request of obtaining that the second subscriber equipment sends.

Alternatively, base station, when in its coverage, the second subscriber equipment sends user device list, sends by broadcast channel or Multicast Channel; When in its coverage, one or more the second subscriber equipmenies send user device list, can send by Multicast Channel, the second subscriber equipment obtains user device list from broadcast channel or Multicast Channel, thus the first user equipment that can carry out D2D communication according to this user device list discovery.

Alternatively, base station is when in its coverage, the second subscriber equipment sends user device list, public search space or dedicated search space by Physical Downlink Control Channel or enhancing Physical Downlink Control Channel send Downlink Control Information to the second subscriber equipment, and this Downlink Control Information carries user device list.All the second subscriber equipmenies in this base station range can get the user device list that Downlink Control Information carries from the dedicated search space of Physical Downlink Control Channel or enhancing Physical Downlink Control Channel from public search space or specific second subscriber equipment in this base station range of Physical Downlink Control Channel or enhancing Physical Downlink Control Channel, thus the first user equipment that can carry out D2D communication according to this user device list discovery.

Alternatively, base station is when in its coverage, the second subscriber equipment sends user device list, by downlink physical shared channel, send user device list, and public search space or dedicated search space by Physical Downlink Control Channel or enhancing Physical Downlink Control Channel send Downlink Control Information to subscriber equipment, this Downlink Control Information carries sign, and this sign is used to indicate the second subscriber equipment and obtains user device list at Physical Downlink Shared Channel.All the second subscriber equipmenies in this base station range can get Downlink Control Information from the dedicated search space of Physical Downlink Control Channel or enhancing Physical Downlink Control Channel from public search space or specific second subscriber equipment in this base station range of Physical Downlink Control Channel or enhancing Physical Downlink Control Channel, then the sign carrying according to this Downlink Control Information obtains from Physical Downlink Shared Channel the user device list that base station sends, thus the first user equipment that can carry out D2D communication according to this user device list discovery.

The method for discovering equipment that utilizes the embodiment of the present invention one to provide, base station adds to the facility information that comprises subscriber equipment D2D ID getting in user device list, then user device list is sent to the subscriber equipment in its coverage, thereby make the user device list that subscriber equipment sends according to base station find to carry out the subscriber equipment that D2D communicates by letter with it.

The Fig. 2 of take below describes a kind of method for discovering equipment that the embodiment of the present invention two provides in detail as example, the flow chart of a kind of method for discovering equipment that Fig. 2 provides for the embodiment of the present invention two.The executive agent of this method for discovering equipment is base station.As shown in Figure 2, this method for discovering equipment comprises the following steps:

Step S201, obtains the facility information of first user equipment.

Wherein, this first user equipment can be specially the subscriber equipment with D2D communication function.Facility information can comprise: the D2D communication capacity of first user equipment, the D2D ID of first user equipment etc.

Step S202, is added to user device list by the facility information getting.

This user device list is a user device list or a plurality of user device list.

When this user device list is while being a plurality of, each user device list has class indication.The mode classification of a plurality of user device lists is not limit.For example, the facility information of the first user equipment in Jiang Zhe community is divided into a user device list, and the facility information of the first user equipment in each adjacent area is divided into respectively to a user device list; Or, classify according to the time that joins user device list, if the facility information of first user equipment that joined user device list in 10 minutes is as user device list 1, in 10-30 minute, join the facility information of first user equipment of user device list as user device list 2,30 minutes are joined above user device list the facility information of first user equipment as user device list 3; Or classify according to the distance between first user equipment and base station, as using the facility information of the first user equipment apart from 100 meters of base stations as user device list 1, using the facility information of the first user equipment apart from base station 5000m as user device list 2, using the facility information of the first user equipment apart from more than base station 5000m as user device list 3.Or the region that base station is covered is divided into a plurality of subregions, the facility information of the first user equipment in every sub regions is as a user device list.

Step S203, sends the class indication of user device list to the second subscriber equipment in base station range.

For making the second subscriber equipment in base station range, know the classification of a plurality of user device lists, base station need send to the second subscriber equipment the class indication of user device list, so that the second subscriber equipment is according to classifying to the corresponding user device list of base station requests.

Step S204, receives the user device list request of obtaining that the second subscriber equipment sends.

Alternatively, this obtains user device list request and carries class indication corresponding to the required user device list of the second subscriber equipment, so that the class indication that base station basis receives, the second subscriber equipment in base station range sends corresponding user device list.

Alternatively, a bit or a plurality of bit are carried in this user device list request.Bit is used to indicate base station and whether to the subscriber equipment in base station range, sends the default user list of devices in a plurality of user device lists, or be used to indicate base station and to the second subscriber equipment in base station range, send user device list corresponding in a plurality of user device lists according to an indicated state of bit, wherein default user list of devices can be one, a plurality of or all user device lists.The corresponding class indication of a plurality of bits, is used to indicate base station and according to class indication corresponding to the plurality of bit, determines the user device list sending to the second subscriber equipment.For example, have 8 user device lists in base station, so the plurality of bit is 3 bits, the class indication of 000 relative user equipment list 1 wherein, and the class indication of 001 relative user equipment list 2, the class indication of 010 relative user equipment list, by that analogy.

Step S205, the second subscriber equipment in base station range sends user device list.

Base station, after receiving the second user device list request that the second subscriber equipment sends, only obtains the second subscriber equipment of user device list request or comprises and send one group of second subscriber equipment of the second subscriber equipment that obtains user device list request or any the second subscriber equipment in base station range sends user device list to transmission.

Alternatively, when obtaining user device list request while carrying class indication, base station is according to the class indication receiving, and the second subscriber equipment in base station range sends the user device list that this class indication is corresponding.

Alternatively, when obtaining user device list request while carrying a bit, if this bit is 0(or 1), base station does not send any user device list to the second subscriber equipment in base station range; If this bit is 1(or 0), base station sends the default user list of devices in a plurality of user device lists to the second subscriber equipment in base station range.

Or, when obtaining user device list request while carrying a bit, if this bit is 0(or 1), base station sends the first default user list of devices in a plurality of user lists to the second subscriber equipment in base station range; If this bit is 1(or 0), base station sends the second default user list of devices in a plurality of user device lists to the second subscriber equipment in base station range.

Alternatively, when obtaining user device list request while carrying a plurality of bit, the user device list that will send is determined according to class indication corresponding to the plurality of bit in base station first, then to the second subscriber equipment in base station range, sends above-mentioned definite user device list.

Base station sends mode from user device list to the second subscriber equipment is identical with the mode that base station in embodiment mono-sends user device list to the second subscriber equipment, does not repeat them here.

The method for discovering equipment that utilizes the embodiment of the present invention two to provide, base station adds to the facility information that comprises subscriber equipment D2D ID getting in user device list, this user device list is a plurality of user device lists, then to subscriber equipment, send the class indication of user device list, so that subscriber equipment can be according to self-demand to the corresponding user device list of base station requests.Base station sends required user device list according to user device list request to the subscriber equipment in its coverage, thereby makes the user device list that subscriber equipment sends according to base station find to carry out the subscriber equipment that D2D communicates by letter with it.

The Fig. 3 of take below describes a kind of method for discovering equipment that the invention process three provides in detail as example, the flow chart of a kind of method for discovering equipment that Fig. 3 provides for the embodiment of the present invention three.The executive agent of this method for discovering equipment is subscriber equipment, and this subscriber equipment may further be the subscriber equipment with D2D communication function.As shown in Figure 3, this method for discovering equipment comprises the following steps:

Step S301, obtains user device list.

This user device list comprises facility information, and this facility information can comprise: the D2D communication capacity of subscriber equipment, the D2D identifier of subscriber equipment etc.
