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.
Correspondingly, the first UE receives the second prompting message that the proximity server is sent, wherein described second
The information for the 2nd UE for including in prompting message has responded the notice message of the first UE for informing the first UE: the two UE, and the
The information of two UE may include the 2nd UE short distance service identification and it is following at least one: the 2nd UE application user mark
Know and the discovery identification code of the 2nd UE, the application user identifier of the 2nd UE and discovery identification code are used to show the 2nd UE pairs
The user which is answered apply.
Further, before the step 204, the short distance service server can be first according to the low coverage of the first UE
The first UE is identified from service identification, and checks whether the first UE allows to send the discovery identification code of the first UE,
When determining that the first UE allows to send the discovery identification code of the first UE, step 204 is executed;When determining the first UE
When not having the permission for the discovery identification code for sending the first UE, then response message can be sent to the 2nd UE, it is described
The notice message that response message is used to show that the first UE to be sent does not pass through authorization.
Specifically, when the first UE carries out short distance service log-on, short distance service server is the first UE distribution first
UE allow using discovery identification code, while short distance service server saves the discovery identification code that can be used of the first UE.Closely
Whether the first UE of discovery identification code inspection that can be used apart from service server according to the first UE of preservation, which has, sends the hair
The permission of existing identification code.Specifically, include in the first prompting message described in the short distance service server judging described
The discovery identification code of one UE whether be the permission that the short distance service server is the first UE distribution discovery identification code;
If so, the short distance service server determines that the first UE allows to send the discovery identification code of the first UE;If it is not,
Then the short distance service server determines that the first UE does not allow to send the discovery identification code of the first UE.
Step 205, the first UE send response message to the short distance service server, and the response message is used for
Show that the first UE has been received by second prompting message, has known that the 2nd UE has responded the notice message.
Correspondingly, the short distance service server receives the response message that the first UE is sent.Specifically, the first UE
Good friend corresponding to the 2nd UE can be learnt nearby according to the second prompting message obtained in step 204, and at this moment the first UE can
To send response message to short distance service server, confirm that it has known that the 2nd UE has responded the notice message.
Further, before step 205, the first UE can first confirm what the short distance service server was sent
Whether the discovery identification code of the first UE in the first prompting message is discovery identification code that the first UE is sent;If it is not,
Then the first UE can not do any response, and the wrong information of the discovery identification code can also be returned to service server, makes low coverage
Stop this from service server closely to find;If so, answering according to the 2nd UE in first prompting message
Determine whether that the 2nd UE has found the first UE with the discovery identification code of user identifier or the 2nd UE;When described
When first UE judgement allows the 2nd UE to find a UE, then execute step 205.
It executes step 205 and illustrates that the first UE determines good friend corresponding to the 2nd UE nearby.
Specifically, the first UE can save its log recording for sending notice message, discovery identification code including transmission and
The time of transmission can check the institute in the first prompting message of the short distance service server transmission by the log recording
Whether the discovery identification code for stating the first UE is discovery identification code that the first UE is sent.
