In the description of the present application, unless otherwise indicated, the meaning of "a plurality" is two or more.
Broadband trunking communication (Broadband Trunking Communication, B-TrunC) is a private network broadband trunking system standard established by the broadband trunking (B-TrunC) industry alliance organization. The method is widely applied to government networks, rail exchanges, electric power, public security, airports and the like.
In the existing B-TrunC standard, a location information service technical architecture and a specific flow are formulated. The location of the cluster terminal can be reported to a location server and provided for user equipment such as a dispatching desk. Since the location information is a relatively sensitive data information, it can cause leakage of the user location information if acquired.
Therefore, how to protect the location information and improve the security of transmitting the location information is a questionable problem,
In order to solve the above problems, the embodiments of the present application provide a communication method, a system, an apparatus, and an electronic device. For example, the first positioning server transmits the parameter information to the terminal after connecting the terminal. Wherein the parameter information includes a first location encryption key. First location information is received from a terminal. The first position information is obtained by encrypting the initial position information by the terminal through a first position encryption key. The initial position information is the current position information of the terminal. The first location information is decrypted with the first location encryption key to obtain initial location information. And encrypting the initial position information by using the second position encryption key to obtain second position information, and sending the second position information to the second positioning server so that the second positioning server sends the second position information to the dispatching desk. Wherein the second location encryption key is generated by the dispatcher when the dispatcher subscribes to the location information of the terminal. The dispatch station is connected to a second location server.
In this way, the application can ensure the safety of the position information in the transmission process of the terminal and the first positioning server by encrypting the initial position information by the first position encryption key. Meanwhile, the decrypted first position information is encrypted again by the first positioning server by adopting a second position encryption key, so that the second position information is obtained, and the safety in the process of transmitting the position information between the first positioning server and the second positioning server and between the first positioning server and the dispatching desk can be ensured. The method prevents unauthorized access and leakage, relates to the application of encryption technology, effectively protects the safety of the position information, and provides more reliable and safe broadband trunking communication service for users.
The communication method provided by the embodiment of the application is applied to core network equipment in broadband trunking system communication.

Wherein the positioning server communicates with xGW through an SGI interface. The S11 interface between xGW and MME is the interface for signaling plane message interaction. In a communication network xGW typically interacts with an MME (mobility management entity) through an S11 port to process and transmit mobility management related signaling messages. These signaling messages include, but are not limited to, attachment, detachment, location update, service request, etc. of the user equipment. xGW may connect to the radio access network device over an S1-T (U) interface. The MME may connect to the radio access network device through an S1-T (C) interface.

The S6a interface between MME and HSS is an interface in LTE (Long-Term Evolution) network for implementing signaling interaction between MME and HSS. The interface is mainly based on Diameter protocol and is used for processing the flows of mobility management, authentication, subscription information processing, user state change notification and the like. The terminal is connected with the wireless access network equipment in a wireless mode.
It will be appreciated that fig. 1 is only a schematic diagram, and that other network devices may be included in the communication system, such as a wireless relay device and a wireless backhaul device. The embodiments of the present application do not limit the number of radio access network devices and terminals included in the mobile communication system.

The embodiment of the application does not limit the application scene of the wireless access network equipment and the terminal.
As shown in fig. 2, an embodiment of the present application provides a flowchart for transmitting location parameter information. The method can comprise the following steps:
Step S201, the first positioning server sends parameter information to the terminal.
In an alternative embodiment, the terminal may receive parameter information from the first positioning server to the terminal after connecting to the first positioning server. The parameter information may include information such as a location switch, a reporting period, a reporting interval distance, a first location encryption key, and the like.
It may be appreciated that, when the first location encryption key is updated, the first location server may timely send the updated first location encryption key to the terminal.
Optionally, in order to better manage and process data related to geographic locations, the location information service is optimized, improving the accuracy and efficiency of subsequent decisions. The first positioning server may also first configure (GIS PARAMETER Configuration, GIS) the geographic information system parameters before sending the location parameter information to the terminal.
Step S202, the terminal sends a response for indicating whether the parameter information is received to the first positioning server.
In the method, the first positioning server and the terminal can synchronize the first position encryption key in a mode that the first positioning server sends the parameter information to the terminal. And encryption and decryption in the subsequent transmission process of the position information are facilitated.
In one possible scenario, the dispatcher may also be connected to the first location server, and the second location encryption key may be generated by the first location server and then synchronized to the dispatcher. In the case where both the terminal and the dispatch station are connected to the first location server, the first location encryption key and the second location encryption key generated by the first location server may be different in order to improve security in the location information transmission process.
As shown in fig. 3, another flowchart for transmitting location parameter information is provided in an embodiment of the present application. The method can comprise the following steps:
step S301, the first positioning server sends the second location encryption key to the dispatch station.
Optionally, before the first positioning server sends the second location encryption key to the dispatcher station, the first positioning server may first configure (GIS PARAMETER Configuration, GIS) the geographic information system parameters.
Step S302, the dispatcher transmits a response indicating whether the second location encryption key is received to the first location server.
In the method, the first positioning server and the dispatching desk can synchronize the second position encryption key by sending the second position encryption key to the dispatching desk by the first positioning server. And encryption and decryption in the subsequent position information transmission process are facilitated.
In another possible scenario, the dispatcher station is not connected to the first location server and is connected to the second location server. The second location encryption key may be determined by the dispatcher when subscribing to the terminal.
As shown in fig. 4, the present application provides a flowchart of a method of subscribing to a terminal. The method comprises the following steps:
step S401, the dispatching desk sends subscription information to the second positioning server.
The subscription information comprises a second location encryption key, an identifier of the subscribed terminal and a location parameter used for limiting the reporting of the location information by the subscribed terminal.
In some embodiments, the subscribed terminal may be a single terminal, and the identifier of the subscribed terminal is a user dialing number (User Dailing Number, UDN). In other embodiments, the subscribed terminals may be terminal groups, and the identifier of the subscribed terminal is a group call number (Group Dailing Number, GDN).
For example, the location parameters used to define the location information reported by the subscribed terminal may be location parameters such as a period of reporting by the terminal, a moving distance parameter, and the like. The present application is not particularly limited thereto.
And step S402, the second positioning server analyzes the code number of the identifier to determine the positioning server connected with the subscribed terminal.
Step S403, the second positioning server sends the subscription information to the positioning server connected by the subscribed terminal.
In some embodiments, the second location server sends subscription information to each location server to which the subscribed terminal is connected, respectively, when the subscribed terminal may be a single terminal.
In other embodiments, the second location server may interact with the TCF to which it is directly connected, requesting to obtain group member information in the subscribed terminal group, while the subscribed terminal may be the terminal group. If the TCF has no group member information, the TCF sends a request message to a group master control cluster control functional entity (Group Trunking Control Function, G-TCF) through a TC2 interface to request the acquisition of the group member information. The G-TCF sends group member information to the TCF directly connected to the second location server via a notification message. The TCF sends group member information to the second location server. And after the second positioning server receives the group member information, the second positioning server respectively sends subscription information to the positioning servers to which the group member information belongs.
It will be appreciated that if a plurality of terminals in the group member information belong to the same location server, the second location server may send a subscription to that location server.
Step S404, the second positioning server receives a plurality of response messages from different positioning servers, which are used to indicate whether subscription information is received.
It will be appreciated that the above response information may further include positioning results, location parameter information, reservation status, time stamp, and other possible additional information of the terminal, so that the scheduling station may make subsequent operations or decisions.
Step S405, the second positioning server merges the plurality of response messages and sends the merged response messages to the dispatching desk.
In the method, when the dispatching desk subscribes to the position information of a certain terminal and/or the position information of the terminal group, the second positioning server sends the second position encryption key to the subscribed terminal, so that the position information is encrypted and transmitted by adopting the second position encryption key in the subsequent process of transmitting the position information of the terminal, and the position information is protected in the transmission process, thereby preventing unauthorized access and information leakage and ensuring the safety of the position information. This mechanism effectively protects the security of the location data.
As shown in fig. 5, an embodiment of the present application provides a flowchart for transmitting location information, which includes the following steps:
step S501: the terminal transmits the first location information to the first location server.
The first position information is obtained by encrypting the initial position information by the terminal through a first position encryption key. The initial position information is the current position information of the terminal.
It is understood that the location information of the terminal may be determined by the terminal through a global positioning system (Global Positioning System, GPS).
Optionally, the first location information further includes a location information encryption indication parameter. The position information encryption indication parameter is used for indicating whether the first position information is initial position information encrypted by the first position encryption key, if the position information encryption indication parameter is a preset first parameter, the first position information is determined to be the initial position information encrypted by the first position encryption key, and if the position information encryption indication parameter is a preset second parameter, the first position information is determined to be the initial position information.
For example, assume that the first parameter is 1. When the location information encryption indication parameter is 1, the first location server may determine that the location information has been encrypted. For another example, assume that the first parameter is 0. When the location information encryption indication parameter is 0, the first location server may determine that the location information is not encrypted.
Optionally, the first location server may store the first location information according to a preset storage rule.
For example, the first location information is decrypted using the first location encryption key to obtain decrypted first location information, the first location information is stored, or the first location information is decrypted using the first location encryption key to obtain decrypted first location information, the first location information is encrypted using the third location encryption key to obtain third location information, the third location information is stored, and the third encryption key is generated by the first location server. Or, the first location information is saved.
Step S502, the first positioning server decrypts the first position information by adopting the first position encryption key to obtain initial position information;
step S503, the first positioning server encrypts the initial position information by using the second position encryption key to obtain second position information, and sends the second position information to the second positioning server.
Specifically, the first positioning server stores a second position encryption key corresponding to the dispatching desk. After receiving the first location information, the first location server may determine a second location encryption key corresponding to the dispatcher station subscribed to the location information of the terminal according to whether the terminal is subscribed to the dispatcher station.
Step S504, the second positioning server sends second position information to the dispatching desk.
Step S505, the dispatching desk adopts the second position encryption key to decrypt the second position information, and initial position information is obtained.
In the method, the first positioning server stores the second position encryption key related to the dispatching desk, so that the encryption transmission of the position information can be ensured by adopting a mode that the second position encryption key encrypts the initial position information to obtain the second position information and sends the second position information to the second positioning server. The encryption transmission mechanism ensures the safety of the position information of the terminal in the transmission process. The method can effectively prevent an unauthorized third party from acquiring or tampering with the position information of the user, thereby protecting the safety of the position information. Meanwhile, by ensuring the encrypted transmission of the terminal position information, the mechanism can obviously reduce the risk of position leakage and provide firm guarantee for the privacy of the user. Today, where network transmissions are increasingly frequent, such encryption mechanisms have an irreplaceable important role in building a secure, reliable network environment. The method not only enhances the safety of data transmission, but also provides powerful guarantee for the integrity and confidentiality of user data.
