Detailed Description
The technical solutions in the embodiments of the present disclosure will be clearly and completely described below with reference to the drawings in the embodiments of the present disclosure, and it is obvious that the described embodiments are only a part of the embodiments of the present disclosure, and not all of the embodiments. The following description of at least one exemplary embodiment is merely illustrative in nature and is in no way intended to limit the disclosure, its application, or uses. All other embodiments, which can be derived by a person skilled in the art from the embodiments disclosed herein without making any creative effort, shall fall within the protection scope of the present disclosure.
The present disclosure provides a method for proximity services (ProSe) establishment, which is described below in conjunction with fig. 1.
Fig. 1 is a flow chart of some embodiments of a method for establishing a proximity service according to the present disclosure. As shown in fig. 1, the method of this embodiment includes: steps S102 to S106.
In step S102, the base station receives an adjacent service matching request sent by the first terminal, where the adjacent service matching request carries an identifier of the first terminal, an identifier of the second terminal, and a service code.
The near service matching Request (Match Request) is transmitted after the first terminal receives broadcast information of the second terminal, and the broadcast information includes: a second terminal identification, a service Code (Code), and an expiration date. The identifier of the terminal is, for example, IMSI (International Mobile Subscriber identity), MSISDN (Mobile station International ISDN Number), or the like. The Code and the corresponding validity period are allocated to the second terminal by the ProSe Function (proximity service Function) in a matching manner, and are used for establishing ProSe connection between the terminals. In the case of coverage, if the terminal needs to use the frequency band resource of the operator, authorization needs to be obtained from the operator and the operator can control and charge, at this time, the terminal needs to obtain a temporary identifier Code uniquely corresponding to the application identifier from the short-distance ProSe Function and then broadcast the Code.
In step S104, the base station authenticates the second terminal according to the identifier of the first terminal, the identifier of the second terminal, and the service code, and determines an application identifier and a validity period corresponding to the service code.
In some embodiments, the base station stores a correspondence of the identity of the first terminal, the identity of the second terminal, the service code, the application identity and the validity period. The correspondence may be stored by the base station during initial establishment of the ProSe connection by the first terminal and the second terminal. Since the signaling interaction in the process of establishing ProSe connection needs to pass through the base station, these correspondences can be stored by the base station.
In some embodiments, the base station determines whether a correspondence relationship between the first terminal and the second terminal is stored according to the identifier of the first terminal and the identifier of the second terminal; the base station searches the stored service code of the second terminal according to the identifier of the second terminal and compares whether the stored service code is consistent with the service code in the adjacent service matching request or not; and determining that the second terminal passes the authentication under the condition that the first terminal and the second terminal have a corresponding relationship and the service codes are matched and consistent.
And if the first terminal and the second terminal do not establish the ProSe connection before, the base station does not store the corresponding relation, and the base station fails to authenticate the second terminal. Therefore, the first terminal and the second terminal can be ensured to pass through the authentication process of the core network before, the resource occupation of the core network is reduced, the efficiency is improved, and meanwhile, the safety of the ProSe connection can be ensured. If the service code is expired or the service code is incorrect, the base station fails to authenticate the second terminal. Through the double authentication of the identification of the terminal and the service code, the safety of the ProSe connection is further improved.
It should be noted that, the authentication process of the base station to the terminal is simpler than that of the core network, and the calculation amount and the signaling interaction process are saved. The authentication process of the core network is the prior art, and is not described herein again.
In step S106, in the case that the authentication is passed, the base station sends an adjacent service matching response to the first terminal, where the adjacent service matching response includes the authentication result, the application identifier, and the validity period of the second terminal, so that the first terminal establishes an adjacent service with the second terminal according to the adjacent service matching response.
The proximity service matching Response (Match Response) includes the second terminal authentication result, the application identifier and the validity period, and the first terminal can know whether the second terminal passes the authentication. Further, since the broadcast information of the second terminal received by the first terminal before includes the validity period corresponding to the service code, the first terminal may detect whether the validity period broadcast by the second terminal is consistent with the validity period in the response of matching the service to the second terminal, thereby performing re-verification on the second terminal. The first terminal may store the identity, service code, application identity and validity period of the second terminal for ProSe connection with the second terminal.
In some embodiments, when the second terminal fails to authenticate or the base station does not find the application identifier and the validity period corresponding to the service code, the base station forwards the proximity service matching request to the core network, so that the core network performs authentication according to the proximity service matching request and returns a proximity service matching response. And under the condition that the authentication of the second terminal fails or the base station does not find the application identifier and the validity period corresponding to the service code, the base station forwards the service matching request to the core network equipment according to the original signaling flow, and the core network equipment processes and responds.
In the method of the embodiment, the first terminal intends to establish the proximity service with the second terminal, sends the proximity service matching request to the base station, and the base station authenticates the second terminal. In the method of the embodiment, the base station executes the authentication process of the second terminal under the condition that the first terminal and the second terminal establish the proximity service again, and does not need to go to the core network for authentication, so that the occupation and waste of core network resources are reduced, and the efficiency of establishing the proximity service is improved.
Further embodiments of the method for establishing a proximity service of the present disclosure are described below with reference to fig. 2.
Fig. 2 is a flow chart of some embodiments of the method for establishing an imminent service according to the present disclosure. As shown in fig. 2, the method of this embodiment includes: steps S202 to S234.
In step S202, the second terminal transmits an imminent service discovery request to the ProSe Function.
This step may be preceded by configuring the second terminal with an application identity. The operator allocates a unique application identifier to the application on the terminal, where the identifier includes a PLMN (Public Land Mobile Network, Public Land Mobile Network information) and application identification information, the PLMN includes a country code and a Network number, and the application identification information uniquely identifies an application, and may also uniquely identify a type of application, such as a hotel, a restaurant, and the like.
The proximity service Discovery Request (Discovery Request) carries information such as an identifier of the second terminal, an application identifier, and the like. The proximity service discovery request is sent to the ProSe Function through network elements such as a base station and an MME (Mobility Management Entity).
In step S204, the ProSe Function interacts with the ProSe APP Server (proximity service application Server) to perform discovery authentication on the second terminal.
The discovery authentication of this step includes: and the ProSe Function(s) requests a user list of the adjacent service from the ProSe APP Server according to the application identifier, confirms whether the second terminal is positioned in the user list and the like.
In step S206, the ProSe Function interacts with an HSS (Home Subscriber Server) to perform discovery authentication on the second terminal.
The discovery authentication of this step includes: and the core network confirms whether the adjacent terminal opens the adjacent service discovery.
In step S208, if the discovery authentication of the second terminal passes, the ProSe Function allocates a service code and a corresponding validity period to the second terminal.
And if the Discovery authentication of the second terminal fails, sending information carrying authentication failure carried by an adjacent service Discovery Response (Discovery Response) to the terminal, and rejecting the request of the second terminal.
In step S210, the ProSe Function sends an adjacent service discovery response to the base station, where the adjacent service discovery response carries the identifier of the second terminal, the application identifier, the assigned service code, and the corresponding validity period.
In step S212, the base station stores the identifier of the second terminal, the application identifier, the assigned service code, and the corresponding validity period.
The base station may record and store the ProSe-related information of the second terminal in this step, or may record and store it in a subsequent step.
In step S214, the base station transmits the proximity service discovery response to the second terminal and allocates a broadcast channel to the second terminal.
The broadcasting of the ProSe is managed and controlled by the base station, so that the personal privacy of the user can be better protected.
In step S216, the second terminal transmits broadcast information using the allocated broadcast information, and accordingly, the first terminal receives the broadcast information of the second terminal.
The broadcast information includes: the identity of the second terminal, the service code and the corresponding validity period. The first terminal acquires the service code and the corresponding validity period of the second terminal through the broadcast information.
The above steps S202 to S216 are procedures for performing ProSe service authorization for the second terminal. Terminals supporting ProSe functionality can discover and communicate with each other only after obtaining authorization from the network side. The ProSe Function is a network element introduced to support ProSe, and mainly completes authorization for terminal discovery and discovery, and a matching process to be described later. In some solutions, the network element is also responsible for the terminals' discovery from each other. The HSS includes all functions of a Home Location Register (HLR), is a permanent storage location for subscriber subscription data, and is located in a subscriber subscription home network. After introducing ProSe, the network element needs to store the subscription data related to ProSe. The ProSe APP Server is used for mapping the application identification of the user and the user identification of the user in the 3GPP network.
In addition to the above Network elements, EUTRAN (enhanced Universal Terrestrial Radio Access Network) provides a bottom Access for ProSe terminals, as well as necessary discovery and communication resources. An enhanced data Core Network (EPC for short) includes an MME and an SGW/PGW (serving gateway/Packet data gateway). The network elements provide bottom layer access for the terminal to access the ProSe Function.
In step S218, the first terminal sends an adjacent service matching request to the base station, where the adjacent service matching request carries the identifier of the first terminal, the identifier of the second terminal, and the service code.
In step S220, the base station authenticates the second terminal according to the identifier of the first terminal, the identifier of the second terminal, and the service code, and determines an application identifier and a validity period corresponding to the service code.
In step S222, in case the authentication is passed, the base station transmits an imminent traffic matching response to the first terminal. The approaching service matching response includes the authentication result, the application identifier and the validity period of the second terminal.
If the first terminal and the second terminal do not establish the ProSe for the first time and the service code of the second terminal is not expired, the base station stores the identifier of the first terminal, the identifier of the second terminal, the application identifier, the service code and the validity period, and the second terminal can pass the authentication.
In step S224, in case the second terminal fails authentication, the base station forwards the proximity service matching request to the ProSe Function.
If the first terminal initiates an adjacent service matching response for the first time aiming at the second terminal, or the second terminal has an error service code, the authentication of the second terminal fails, and the base station cannot find the application identifier and the validity period corresponding to the service code.
In step S226, the ProSe Function interacts with the core network device to perform an authentication process, and obtains an application identifier and a validity period of the second terminal.
In step S228, the ProSe Function transmits an imminent traffic matching response to the base station. The approaching service matching response includes the authentication result, the application identifier and the validity period of the second terminal.
In step S230, if the authentication is passed, the base station stores the corresponding relationship between the identifier of the first terminal, the identifier of the second terminal, the application identifier, the assigned service code, and the validity period.
Step S212 is an optional step, that is, if the base station does not execute step S212, the base station may also store the ProSe related information and the corresponding relationship of the first terminal and the second terminal in step S230. The first terminal may be multiple, that is, the base station may maintain the correspondence between multiple terminals and the second terminal.
In some embodiments, after the validity period corresponding to the service code expires, the base station deletes the stored corresponding relationship between the identifier of the second terminal, the service code, the application identifier, and the validity period. Or the base station receives the information deletion request sent by the second terminal, and deletes the stored corresponding relation among the identifier of the second terminal, the service code, the application identifier and the validity period.
In step S232, the base station transmits an imminent traffic matching response to the first terminal.
After receiving the close service matching response, the first terminal may verify the authenticity of the second terminal according to the validity period in the close service matching response and the stored validity period of the second terminal. The communication security is improved through the bidirectional authentication of the base station and the first terminal.
In step S234, the first terminal establishes a ProSe connection with the second terminal according to the proximity service matching response.
The method of the embodiment is suitable for the scene that the terminals in the same base station complete quick networking in the scenes of a factory, a school and the like, does not need to pass through a core network for each authentication, occupies the resources of the core network, and can ensure the safety between the terminals by establishing the authenticated networking through the cellular network.
