Below in conjunction with the accompanying drawing in the embodiment of the present invention, the technical scheme in the embodiment of the present invention is clearly and completely described, it is clear that described embodiment is only a part of embodiment of the invention, rather than whole embodiments.Based on the embodiment in the present invention, those of ordinary skill in the art are not making creation Property work under the premise of the every other embodiment that is obtained, belong to the scope of protection of the invention.Firstly the need of explanation, described closely business in the application refers to a terminal in physics short range it can be found that other terminal, and the business for the communication that can be optimized with other terminal.Wherein, the communication of optimization can refer to communication data between terminal can without mobile operator network, but use the frequency range arranged between terminal to be directly transmitted.Specifically, closely business includes：Directly voice data transmission, which is carried out, between terminal directly carries out file data transfer between the business of call, terminal to realize direct business for carrying out short message data transmission so as to realize transmitting-receiving short message etc. between the business of file transmission, terminal so as to realize.

Fig. 1 is the flow chart of the closely service log-on method embodiment 1 of the application.As shown in figure 1, this method can include：

Step 101:Terminal determines whether network supports closely business；The network that the network is presently in for the terminal, or the network that the terminal will be switched to；

The terminal can support the closely equipment such as mobile phone of business.The terminal can pass through base station

The broadcast of (EvolvedNode B, eNodeB) obtains the closely professional ability information of the network.The closely professional ability information can represent whether the network supports closely business.The base station can by with mobility management entity（MME the closely professional ability of the network where the signalling interactive process acquisition terminal between), the closely professional ability of the network where the configuration information acquisition terminal that can also in itself have by base station.Specifically, MME can be in the prior art set up with eNodeB in the SI signalings of SI flows, carry network closely professional ability information.ENodeB can be in S1 signalings closely professional ability information know the closely professional ability of network.

The network can be the network that the network that the terminal is presently in or the terminal will be switched to.

Step 102:When the network support closely business, the registration request of closely business described in opening is sent to closely service server；

Proximity server can obtain the signing information of the terminal.The information for having the terminal whether to open closely business is recorded in the signing information.If the terminal has opened closely business, the closely service server is received described in unlatching after the closely registration request of business, it is possible to open the closely business of the terminal；If the terminal does not open closely business, the closely service server is received described in unlatching after the closely registration request of business, can refuse to open the closely business of the terminal. Step 103:When the network does not support closely business, the registration request of closely business described in closing is sent to the closely service server.

If the terminal is in registration process before, closely business is opened, then the closely service server is received described in closing closely after the registration request of business, can close the closely business of the terminal.If the terminal is in registration process before, closely business is not turned on, then the closely service server is received described in closing closely after the registration request of business, can not do any response.

Be between above-mentioned steps 102 and step 103 and/or relation, there may be the embodiment including step 101, step 102 and step 103, can also exist includes the embodiment of step 101 and step 102, and can also exist includes the embodiment of step 101 and step 103.

In summary, the closely service log-on method of the present embodiment, by determining whether network supports closely business, during so that terminal being registered on network, the ability of network support closely business can be known, do not support to initiate the situation of closely service request in the closely network of business so as to avoid generation terminal from being in so that the signaling consumption of communication system is minimized.It is the flow chart of the closely service log-on method embodiment 2 of the application referring to Fig. 2.The flow can include：

Step 201:Base station (eNodeB) sends S1 to mobility management entity (MME) and sets up request；Step 202:MME sends S1 to eNodeB and sets up response；Response bag of the S1 setting up contains the closely business of network（ProSe) ability information；

Step 201 and step 202 are optional steps.ENodeB and MME is interacted by the S1 Establishing process of existing S1 signalings, obtains the ProSe ability informations of network.ProSe ability informations can indicate whether this network can support ProSe business.If eNodeB can obtain the ProSe ability informations of network according to configuration information, above-mentioned two step can be skipped.

Step 203:Base station sends the broadcast of the closely professional ability comprising network to user equipment；Step 204：User equipment sends closely service request to MME；Customer equipment identification can be included in the request, and is turned on or off the information of closely business.

User equipment can determine whether network supports closely business according to the broadcast received；When the network support closely business, the registration request of closely business described in opening can be sent to closely service server by MME； When the network does not support closely business, the registration request of closely business described in closing can be sent to the closely service server by MME.

Customer equipment identification can be included in the request, and is turned on or off the information of closely business, the configuration information to closely business can also be included.

Device identification can be the IMSI or MSISDN of the equipment or the equipment temporary mark etc. of network allocation.The message can use the Non-Access Stratum such as existing network Attach Request message, or location update message (NAS) message or equipment to be sent to MME Access Layer by base station（AS) message.

The configuration information can be the closely discovery configuration information of user equipment.Closely find that configuration information can include：" it can be found that others; but can not be found ", " it can be found that others can also be found ", " others cannot be found, can not be found ", " cannot find others; but allow to be found ", " inquiring whether I allow to be found by other side every time ", it is allowed to find the device identification list of oneself, does not allow to find the device identification list of oneself.

Step 205:The closely service request that user equipment is sent is forwarded to proximity server (Prose Server) by MME;

Step 206:Closely service server is received after closely service request, judges whether the user equipment allows to carry out closely business.If it is allowed, then receiving the closely service request；Refuse the closely service request of equipment if not allowing.

Closely device identification can be sent to home subscriber server by service server（), HSS the subscription data of equipment is obtained from HSS.Subscription data includes the information whether equipment allows to carry out closely business.Closely service server can determine whether the closely business of the equipment according to the subscription data of acquisition.It if closely having obtained equipment subscription data before service server, need not be obtained again from HSS, the closely business of the equipment can be directly determined whether according to the equipment subscription data that closely service server is locally preserved.

Step 206:Proximity server sends closely business received message to MME.The device-to-device mark distributed for the user equipment can be included in the closely business received message（D2D ID) and device-to-device password（D2D Code ).

D2D Code and the D2D ID that closely service server can distribute for the equipment, can also preserve the customer equipment identification received, and user equipment to the configuration information of closely business.

D2D Code and the D2D ID that the ProSe of near field communication devices sets and distributed for the equipment.Optionally closely service server preserves the closely discovery configuration information of the equipment. In step 206, closely the routing iinformation of oneself can be supplied to equipment by service server, so that equipment is in follow-up application layer interaction, the closely service server routing iinformation of acquisition can be supplied to application layer services device, application layer services device can find the closely service server progress interacting message that equipment is registered according to routing iinformation, to obtain closely business service.Routing iinformation can be the server identification of closely service server, such as, but not limited to Uniform Resource Identifier（), URI it can also be the forms such as IP address.

Closely service server can also carry routing iinformation in the D2D ID of equipment are distributed to, for example, the D2D ID for distributing to equipment are defined as to the form of " device d2d id@proximityserver URI ".Or different closely service servers can use different D2D ID scopes（Range), so equipment is in follow-up application layer interaction, D2D ID are supplied to application layer services device, application layer services device can directly extract the routing iinformation of closely service server from D2D ID, or according to the routing iinformation of D2D ID range-based searching to corresponding closely service server, so as to obtain closely business support from closely service server.

Optionally, closely service server is that the near field communication devices distribute a decruption key, is sent to user equipment by MME in this step.Subsequent user equipment, from when closely service server obtains encrypted content, can use the decruption key to be decrypted by application layer services device.

Step 207:MME to user equipment forward described in closely business received message.

Can be sent by NAS message, or by base station equipment is sent to using AS message.Step 208:User equipment is to application layer services device（Application Server) send device-to-device service registration request（D2D Service Registration Request ).The device-to-device service registration request can include device-to-device mark（ D2D ID ).

User equipment can send D2D service registration requests to application server, wherein carrying the D2D ID that closely service server is distributed to equipment, application server preserves its D2D ID.Optionally, the routing iinformation of closely service server can be carried in D2D ID, application server can be with routing iinformation to corresponding closely service server, pass through closely service server judging D2D ID legitimacy, if illegal, application server can refuse D2D service registration requests.

Step 209:Application layer services device sends D2D Code new informations to MME.

Step 209 is optional step, if closely service server receives the D2D service registration requests of application server transmission, and confirms that D2D ID are legal, then can distribute new D2D Code to equipment according to the application specifically registered.This D2D Code is relevant with the application registered.The closely month good business device of business The D2D Code updated are sent to MME.If not distributing new D2D Code, the step is skipped.Step 210:The D2D Code new informations are forwarded to the user equipment by MME.

It should be noted that in the present embodiment, user equipment can also not pass through with closely service server

MME and carry out direct interaction.In the case of direct interaction, it is convenient to omit forwarding steps of the MME for message closely between service server and user equipment.

Terminal（That is user equipment）Complete after registration process, it is possible to enter new cell.Cell can be the least unit for the network for supporting ProSe.Tracking area hereinafter（Tracking Area, Τ Α) concept be greater than cell.One tracking area can include multiple cells.When terminal enters new cell, it can adopt in the following method.

When the terminal enters new cell, it may be determined that whether the cell supports the closely business；When closely professional ability changes of cell belonged to before closely professional ability is relative to terminal of the cell, terminal can initiate to change the flow that closely business is set.Specifically, the closely professional ability of cell changes, including two kinds of situations：The first situation is the cell that terminal does not support closely business by supporting the cell of closely business to enter；Second of situation is the cell that terminal supports closely business by not supporting the cell of closely business to enter.

In the first scenario, when the cell does not support the closely business, the first tracing section updating request comprising closely business closing information is sent to base station, so that first tracing section updating request is forwarded to mobility management entity by the base station, the mobility management entity sends the closely request of business described in closing to the closely service server.

In the latter case, when closely business described in cell support, the second tracing section updating comprising closely service configuration information can be sent to base station to ask, so that second tracing section updating request is forwarded to mobility management entity by the base station, the mobility management entity sends the request for opening the closely business to the closely service server, and the closely service server is according to closely business described in closely service configuration information unlatching.

When Fig. 3 changes for the ability of cell, the terminal change flow chart that closely business is set.As schemed

Shown in 3, the flow can include：

Step 301:The broadcast that base station occurs to carry capability information to user equipment.Whether the cell that the capability information can represent new supports closely business.

User equipment according to the broadcast, can judge whether the closely professional ability of network changes.In the event of changing, then step 302 can be triggered. Step 302:User equipment sends tracing section updating request to base station（TAU Request ).Wherein, TAU is Tracking Area Update abbreviation.Tracing section updating request can use the existing signaling in existing TAU flows to carry corresponding configured information and be realized.Need to carry configured information in the tracing section updating request.The configured information can be the configured information for representing to be turned on and off closely business.

Step 303:Tracing section updating request is forwarded to MME by base station.

Step 304:Configured informations of the MME in tracing section updating request sends the request for the closely business that is turned on and off to proximity server.

Closely service server can determine whether the ProSe business of the equipment from log-on message.If closely the service server judging equipment does not allow to use ProSe business, refuse the closely service request information.If closely service server judging allows the ProSe business of the equipment, the ProSe that storage near field communication devices update is set, and performs step 305.

Step 305:Closely service server sends closely business received message to MME.The message can represent that closely service server has been successfully updated the ProSe of equipment and set.

Step 306:MME sends tracing section updating response to base station（TAU Response), signals base TAU flows successful execution.

Step 307:Base station forwards the tracing section updating to respond to user equipment, informs that user equipment has been successfully made TAU flows, and be successfully updated the ProSe settings of equipment.

It should be noted that the user equipment can have connected state and Idle state two states.When the user equipment is Idle state, the method in Fig. 3 can be directly used.When the user equipment is connected state, it is necessary to increase switching flow between step 301 and step 302.User equipment can be switched to target eNodeB from source eNodeB and data are switched to new eNodeB by the switching flow, data is entered core net from new eNodeB and be transmitted.In the connected state, data are transmitted by core net in original network and the network being switched to, rather than are transmitted by D2D connections.Present invention also provides a kind of closely service updating method.Fig. 4 is the flow chart of the closely service updating method embodiment 1 of the application.The flow can include：

Step 401：Base station sends S 1 to MME and sets up request.

The S1, which is set up in request, can include the closely professional ability information of the base station.Whether the network that the closely professional ability information can represent terminal and will be switched to supports closely business.

Step 402：The ProSe ability informations of MME storage networks, and set up to eNodeB transmissions S 1 Response message informs eNodeB corresponding informations.

Step 403:Base station sends to user equipment and broadcasted, and informs whether the cell of user equipment switching supports ProSe business.

Step 404:User equipment sends tracing section updating request to base station.

The tracing section updating request can use the existing signaling in existing TAU flows to realize.Compared with the flow in Fig. 3, the tracing section updating request in this flow does not carry configured information.

Step 405：Base station forwards the tracing section updating to ask to MME.

Upon receiving the request, meeting is according to the closely professional ability information of the network stored in step 401, and the cell where before judging user equipment is relative to the new cell that will go into, and whether ability changes by MME.If closely professional ability changes, step 406 is performed.
