Specific embodiment

In order to make the object, technical scheme and advantages of the embodiment of the invention clearer, below in conjunction with the embodiment of the present invention In attached drawing, technical scheme in the embodiment of the invention is clearly and completely described, it is clear that described embodiment is A part of the embodiment of the present invention, instead of all the embodiments.Based on the embodiments of the present invention, those of ordinary skill in the art Every other embodiment obtained without making creative work, shall fall within the protection scope of the present invention.

The function of short distance business (ProSe) is by wireless access on the global land of evolution in 3GPP Rel-12 (Evolution-Universal Terrestrial Radio Access, referred to as: E-UTRAN) and UE are supported.For branch The UE for holding ProSe can be found that the UE of other supports ProSe in close position, and can be built by close range communication techniques Vertical near field communication is directly communicated between equipment and is transmitted without core net in communication process.For The UE of the support ProSe on network is resided in, network side will be controlled and be configured to its ProSe characteristic, and UE is according to ProSe spy Property control parameter execute ProSe operation.Whether the parameter of ProSe characteristic may include: it can be found that other ProSe UE, if It can be found by other ProSe UE；Whether ProSe communication can be carried out；Whether it can be found that by other public land mobile networks The UE of the support ProSe of the E-UTRAN service of network (Public Land Mobile Network, referred to as: PLMN)；ProSe hair The maximum short range grade that now can be used.

In a network, be provided in each PLMN server (ProSe Function) Lai Jinhang of short distance business for The control of the ProSe characteristic of UE can be by visited place short distance service server (V-ProSe for being in the UE of visited network Function) and ownership place short distance service server (H-ProSe Function) carries out the control of ProSe characteristic together.Closely The ProSe configuration information that UE can be stored apart from service server, the parameter including ProSe characteristic mentioned above, to reach Control the purpose of ProSe characteristic.

As stated in the background art, it in existing short distance discovery method, supports directly to interact between the UE of ProSe, UE to be found cannot reliably receive the discovery response message of other UE.It is existing close due to directly being interacted between UE There is also safety problem, concrete reasons for distance discovery method are as follows: includes the discovery identification code of user, attack in discovery response message Which person can know by detection notice message announcing message and discovery response message response message It is a little to find that the corresponding user of identification code is the good friend of UE to be found (being set as the first UE).Potential threaten is that attacker can be false It emits the first UE and sends the notice message announcing message of the first UE, so that the good friend for getting the first UE (sets Response message is responded for the discovery of the 2nd UE or the 3rd UE), at this moment the 2nd UE and the 3rd UE cannot recognize that the UE It is the first UE of personation, so that the file of oneself is further sent to attacker；Also, attacker can be with counterfeit 2nd UE Discovery response response message is sent to the first UE, at this moment the first UE can not identify that the UE is therefore attacker deposits In security risk.In addition, since the radio resource that prior art short distance discovery method uses belongs to operator, but in this method It is directly interacted between UE, without any network equipment, i.e. this method is invisible and uncontrolled for operator, The interests of operator are not met.

For ease of description, UE to be found, i.e. transmission notice message announcing message are indicated with the first UE UE, the UE for sending discovery response response message is indicated with the 2nd UE, wherein the first UE and the 2nd UE In include short distance service application (ProSe application), also, comprising extremely in the first UE and the 2nd UE Few a identical application, such as QQ, wechat etc., and the corresponding user of the first UE user corresponding with the 2nd UE For the user of at least a same application.

It should be noted that the first UE and the 2nd UE may be it is multiple, only with one in the embodiment of the present invention and attached drawing It is a to indicate.And when implementing, actual UE can be provided simultaneously with the function of the first UE and the 2nd UE, i.e. a UE is being sent out Out while notice message, the notice message of other UE transmission can also be monitored, and is responded.

Fig. 1 is the network structure that the present invention closely has found system.As shown in Figure 1, short distance hair provided by the invention Existing method, is arranged short distance service server (ProSe Function) in a network, close by short-range communication server- aided Apart from discovery procedure, wherein short distance service server is connect with mobile management entity and gateway, UE net by wireless communication The access net and short distance service server of network carry out information exchange.Fig. 2 is the present invention closely discovery embodiment of the method one Interaction diagrams, as shown in Fig. 2, the present embodiment is related to the first UE, the 2nd UE and short distance service server (ProSe Function the interactive operation between), wherein the first UE is the use in addition to the 2nd UE in the application in the 2nd UE Family.The method of the present embodiment may include:

Step 201, the first UE broadcast transmission notice message, mark and institute in the notice message including the first UE State the discovery identification code of the first UE.

Specifically, the notice message (Announcing message) is closely to find notice message, reception pair As for all UE near the first UE, as long as that is, neighbouring UE opens the monitor function of short distance service application, Ji Kejian Hear the notice message.The mark for the first UE for including in the notice message can be the short distance service identification of the first UE (ProSe UE ID), which can be is divided when carrying out short distance service log-on by ProSe function for UE Match, for identification the first UE；The discovery identification code (Announcing code) for the first UE for including in notice message can also With in ProSe service log-on by ProSe function be the first UE in short distance service application (ProSe Application it) distributes.Wherein, discovery identification code can be for identifying some user or groups of users or some application User, groups of users or application in first UE are also possible to user, groups of users or application that UE wishes discovery.

First UE can declare that the first UE is certain by the peripherad UE of discovery identification code in the notice message It is a that some user for oneself wishing to find is broadcasted using user or peripherad UE.

Step 202, the 2nd UE are determined according to the discovery identification code of the first UE to be needed to find mutually with the first UE.

Specifically, after the 2nd UE listens to the notice message of the first UE transmission, first can be determined according to discovery identification code UE is the good friend of user (application user) of the application in the 2nd UE or some user in the 2nd UE is first UE wishes the user of discovery, such as the first UE and the 2nd UE include wechat, and in notice message of the 2nd UE according to the first UE Discovery identification code determine the corresponding user of the first UE be the corresponding wechat user of the 2nd UE good friend, then the 2nd UE can be true It is fixed to need to find mutually with the first UE.When specific implementation, the 2nd UE can show that good friend corresponding to the first UE exists on interface Near, and determined after user's confirmation and need to find mutually with the first UE.

Specifically, it can store one or more good friend of some short distance service-user in the 2nd UE in the 2nd UE Application layer identification become reconciled the corresponding discovery identification code of friendly user, the 2nd UE according to the discovery identification code received so as to knowing Not Chu the corresponding user of announcing code that sends of the first UE whether be user in the 2nd UE good friend.

Step 203, the 2nd UE send the first prompting message, first prompting message to short distance service server In include in include the first UE short distance service identification, the discovery identification code of the first UE and the letter of the 2nd UE Breath, the information of the 2nd UE include the 2nd UE short distance service identification and it is following at least one: the 2nd UE Using the discovery identification code of user identifier and the 2nd UE.

Correspondingly, receiving the first prompting message that the 2nd UE is sent, first prompting message apart from service server It can be closely discovery prompt (ProSe Discovery Alert) message.2nd UE is requested by first prompting message Short distance service server in network checks whether the discovery announcement operations (sending notice message) of the first UE are the behaviour authorized Make, meanwhile, request proximity server that short distance discovery response is sent to the first UE if by authorization.

Wherein, the 2nd UE's for including in the message uses using user identifier and the discovery identification code of the 2nd UE In which the good friend user for making the first UE know that the 2nd UE is corresponded to and which is applied.

In this step, UE and short distance service server, which establish communication, can establish communication by the connection in user face, Or communication can be established by mobile management entity (Mobile Management Entity, referred to as: MME).Wherein, user The connection in face specifically: after UE access to mobile communications network, mobile network is that the UE establishes data connection, in mobile network Network is that the UE distributes the address Internet Protocol (internet protocol, referred to as: IP), and the UE is to pass through the gateway accessing To external data network.Therefore, UE can pass through dynamic domain name system (Domain Name System, referred to as: DNS) inquiry The IP address of proximity server is obtained, the connection with proximity server is then established using IP agreement.

When being connected by user face, UE is linked into short distance service server by its established user face；It is logical When crossing mobile management entity foundation communication connection, the message for being sent to short distance business is encapsulated in Non-Access Stratum (Non by UE Access Stratum, referred to as: NAS) mobile management entity is sent in message, low coverage is then sent to by mobile management entity From service server.

Step 204, the short distance service server send the second prompting message, second prompt to the first UE The information of discovery identification code and the 2nd UE in message including the first UE.
