Description
Technical Field
The invention relates to the technical field of wireless technology, in particular to a positioning processing method, an MEC server and a base station.
Background
In a service scenario of indoor positioning by using a mobile communication network, when a user needs to acquire own position information, a position information request is initiated to a mobile edge computing (Mobile Edge Computing, MEC) server by a third party application server, and the MEC server returns corresponding position information according to user internet protocol (Internet Protocol, IP) information carried in a data packet body.
Specifically, the process of acquiring positioning information in the prior art mainly includes the following steps:
the user requests the self-position information from the third party server, and the base station sends the request information to the core network;
the core network converts the IP of the user intranet into the IP of the public network according to the IP address mapping relation between the user intranet and the public network, and sends a positioning request to a third-party server;
the third party server extracts the IP information of the public network of the user and requests the location information of the target user from the MEC positioning server;
in the above process, the base station continuously provides the relevant information of all the wireless signals of the users in the cell and the user identity information to the MEC server, and the MEC server calculates the positions of the users based on the information and stores the information, and simultaneously obtains the mapping relationship among the user intranet channel ID, intranet IP and public network IP from the core network. When receiving a positioning request sent by a third-party server, determining information of a target user in the stored position information, and feeding back the information to the third-party server;
the third party server returns the user positioning information to the user who initiates the request through the core network (IP conversion) and the base station in turn.
Therefore, when the mobile terminal requests the position information in the network, the mobile terminal accesses the third party application server step by step through the access network, the core network and the Internet to acquire the position information. However, there is no unified authentication procedure of the MEC server for the third party server to initiate the location request, that is, when the MEC server receives the location information request of the third party server, the MEC server will generally directly query and return the location information of the corresponding user. Because the positioning request and the positioning information of the user are sent to the MEC server through the third-party server, the third-party server can acquire the user information for initiating the positioning request, and the problem of infringement of the privacy of the user possibly exists; in addition, the MEC server does not have the standard identification and authentication flow aiming at the position request information at present, which may cause data leakage and threaten the security of the mobile communication network.

The positioning processing method of the embodiment of the invention is applied to a wireless communication system, and the wireless communication system can realize indoor positioning through a mobile communication network.
As shown in fig. 1, a wireless communication system adopting the positioning processing method according to the embodiment of the present invention includes a mobile terminal, a base station, an MEC server, and a core network. The connection among the terminal, the base station, the MEC server and the core network may be wireless connection.
In the embodiment of the present invention, the base station may be a commonly used base station, an evolved node b (evolved node base station, eNB), or a network side device in a 5G system (for example, a next generation base station (next generation node base station, gNB) or a transmitting and receiving point (transmission and reception point, TRP)) or a cell.
The base station can provide the relevant information and user identity information of all mobile terminals in the cell to the MEC server, and the MEC server can calculate the positions of the mobile terminals.
In order to solve the problem that the prior art MEC server does not recognize and authenticate a position request and possibly causes data leakage, the embodiment of the invention provides a positioning processing method, and the MEC server can authenticate the positioning request message through IP information in the positioning request message so as to avoid causing data leakage.
Specifically, as shown in fig. 2, one of the positioning processing methods according to the embodiments of the present invention is applied to a mobile edge computing MEC server, and includes:
s210, acquiring a positioning request message sent by a base station;
s220, authenticating the positioning request message according to the Internet Protocol (IP) information in the positioning request message;
And S230, when the authentication of the positioning request message is passed, sending the positioning information requested by the positioning request message to the base station.
Compared with the prior art, the MEC server can authenticate the positioning request message through the IP information in the positioning request message by adopting the positioning processing method disclosed by the embodiment of the invention so as to avoid data leakage; in addition, the MEC server can directly acquire the positioning request message sent by the base station, and send the determined positioning information to the base station, and the base station sends the positioning information to the mobile terminal.
Specifically, as shown in fig. 3, in step S210, a location request message sent by a base station for obtaining location information of a target user is obtained, including:
s211, acquiring a request message sent by a base station;
s212, when the target IP address of the packet header of the request message is matched with the address of the MEC server, determining that the request message is a positioning request message.
When the positioning processing method provided by the embodiment of the invention is adopted, a user can send a request message to a base station through a mobile terminal, and the base station sends the request message to an MEC server; the MEC server judges whether the request message is a positioning request message or not by analyzing a target IP address of a data packet header of the request message; if the destination IP address of the packet header matches the address of the MEC server, that is, the destination IP address of the packet header is the address of the MEC server, it is determined that the received request message is a positioning request message sent to the MEC server, and step S220 may be further performed.
Optionally, when the destination IP address of the packet header of the request message does not match the address of the MEC server, it is determined that the request message is not a positioning request message, and the request message needs to be further sent to the core network.
In the embodiment of the invention, the data packet body of the positioning request message comprises IP information, and the positioning request message is used for requesting to acquire the positioning information of the mobile terminal corresponding to the IP information; or alternatively
The data packet body of the positioning request message does not comprise IP information, and the positioning request message is used for acquiring the positioning information of the mobile terminal corresponding to the source IP in the data packet head of the positioning request message.
Specifically, in the positioning processing method according to the embodiment of the present invention, a data packet of a positioning request message includes a packet header and a packet body, where the packet header includes a source IP address and a destination IP address, and the source IP address is an address of a location request initiating user; the target IP address is the address of the MEC server, and when the MEC server receives the request message, the target IP address in the request message is used as a judging basis for judging whether the request message is a positioning request message or not; the packet body of the positioning request message may or may not include IP information. The method comprises the steps that through the inclusion of IP information, a positioning request message is used for requesting to acquire positioning information of a mobile terminal corresponding to the IP information; the location request message is used to obtain location information of the mobile terminal corresponding to the source IP address in the packet header by excluding the IP information.
As shown in fig. 4, step S220 of authenticating the positioning request message according to the internet protocol IP information in the positioning request message includes:
s221, authenticating a source IP address in a packet header of the data packet of the positioning request message according to the pre-acquired user bearing address ID;
and S222, when the source IP address passes the authentication, if the data packet body of the positioning request message comprises IP information, the IP information in the data packet body is authenticated, and when the IP information in the data packet body passes the authentication, the authentication of the positioning request message is determined to pass.
According to the authentication mode, the MEC server authenticates according to the data packet structure of the received positioning request message and determines whether to provide positioning information.
Specifically, in step S221, the authenticating the source IP address in the packet header of the positioning request message according to the pre-acquired user bearer address ID includes:
judging whether a source IP address in a data packet header of the positioning request message is matched with a pre-acquired user bearing address ID;
and when the source IP address is matched with the user bearing address ID, determining that the authentication of the source IP address is passed.
Specifically, when the source IP of the packet header of the data packet of the positioning request message is matched with the user bearing address ID, the packet header information of the positioning request message is considered to be not tampered, and the positioning request message can be further authenticated according to the IP information in the packet header of the positioning request message;
when the source IP of the packet header of the positioning request message does not match the user bearer address ID, the content of the packet of the positioning request message may be considered as tampered by other users/applications, and the MEC server does not process the packet.
Optionally, the positioning processing method according to the embodiment of the present invention further includes:
the user bearer address ID is obtained from the core network.
Specifically, the core network may send the user bearer address ID of the mobile terminal that initiates the positioning request message and a mapping relationship between the user bearer address ID and the intranet IP to the MEC server. It can be understood that when the positioning request message is sent, the source IP address of the packet header of the positioning request message corresponds to the intranet IP address, so as to determine whether the packet header information of the positioning request message is tampered according to the source IP address in the packet header of the positioning request message and the user bearer address ID obtained in advance from the core network and corresponding to the mobile terminal sending the positioning request message. Optionally, after step S221, the method further includes:
When the source IP address passes the authentication, if the data packet body of the positioning request message does not comprise IP information, determining that the authentication of the positioning request message passes.
Specifically, if the data packet body of the positioning request message does not include the IP information, the mobile terminal is considered to request for own position information, and if the data packet is determined to have the position request authority, the corresponding position information is returned to the mobile terminal according to the user bearing address ID.
Optionally, in step S222, when the source IP address passes the authentication, if the data packet body of the positioning request message includes IP information, the authentication on the IP information included in the data packet body includes:
and authenticating the IP information according to the configuration relation between the first mobile terminal corresponding to the source IP address in the pre-acquired data packet header and the second mobile terminal corresponding to the IP information included in the data packet header.
Specifically, the configuration relation can be obtained in advance through a core network, the relation between the source IP address of the packet header of the data packet of the positioning request message and the IP information in the packet body can be configured in the configuration relation, and the relation can determine whether the mobile terminal (the second mobile terminal) corresponding to the IP information in the packet body hopes that the mobile terminal (the first mobile terminal) corresponding to the source IP address in the packet header obtains the position information of the mobile terminal; if the first mobile terminal is determined to have permission to acquire the position information of the second mobile terminal according to the preset configuration relation, the requested position information can be returned; if the first mobile terminal is determined to have no authority to acquire the position information of the second mobile terminal according to the preset configuration relation, the positioning request message is not processed.
