The preset condition includes a preset position relationship, that is, the position information of the terminal to be called is in accordance with a preset position threshold. It can also be understood that the terminal to be called is obtained from the terminal whose position relation with the calling terminal meets the preset position relation based on the position calling so as to confirm whether the group calling can be joined. The position threshold value configured in advance can be set according to needs, for example, the position threshold value can be set in a small range (100 meters) at a place where the calling terminal is densely located; in the open air, the jungle executes tasks and the position threshold value can be set to be larger (1 kilometer) during patrol, namely when the position information of the terminal MSn meets the requirement of the position threshold value, the terminal MSn can be listed as a terminal to be called. It is understood that in all embodiments the established connection may be understood as an established communication connection. It is understood that the number of the terminal MSn to be called may be plural.
S3, the cluster network side sends a call request corresponding to the group call to the terminal to be called MSn, so that the terminal to be called MSn joins the group call; specifically, after acquiring member information meeting the requirement of the position threshold, namely all the information of the terminals MSn to be called, a call request is sent to the terminals MSn to be called, and after receiving the group call request, the terminals MSn to be called can join the group call according to the group call request, so that the group call based on the position is formed.

Specifically, when the calling terminal MS0 directly initiates a location information rescue group call to the master trunking service controller TSC1, sometimes the trunking service controller may also be understood as a single base station, and the master trunking service controller TSC1 stores all terminal information connected to the trunking network side, that is, it may be understood that the terminal here may include not only a terminal directly connected to the master trunking service controller TSC1, but also all terminals in the trunking network side connected to the master trunking service controller TSC1 and indirectly connected to the master trunking service controller TSC1 through various hierarchical networks. The TSC1 initiates signaling identification to judge as position information rescue group calling, and the TSC1 acquires all stored terminal information, including a terminal MSn to be called meeting preset conditions, according to the reference position information of the calling terminal MS0 and preset conditions. The number of the terminals MSn to be called here may be multiple, and the master trunking service controller TSC1 establishes the group call and performs call establishment on the terminals MSn to be called, and the terminals MSn to be called join the group call after receiving the group call request.

Specifically, the trunking network side may be formed by a plurality of trunking service controllers which are connected in a distributed manner, when the trunking network side includes at least one trunking service controller, namely, other trunking service controllers TSC2, connected with the main trunking service controller TSC1, the main trunking service controller TSC1 receives the location information rescue group call of the calling terminal MS0 and judges the location information rescue group call by the signaling identifier, the location information of the calling terminal MS0 and the corresponding information of the group call request, such as the signaling of the group call identifier having the location information call, may be sent to at least one other trunking service controller TSC2 connected therewith, the other trunking service controllers TSC2 obtains the terminal MS2 to be called corresponding to the other trunking service controllers TSC2 according to the reference location information and the preset condition, the main trunking service controller TSC1 obtains the terminal MS1 to be called corresponding to the main trunking service controller TSC1 according to the reference location information and the preset condition, the corresponding relationship between the cluster service controller and the terminal can be understood as a direct connection relationship. Namely, the other trunking service controllers TSC2 are in direct connection with the terminal MS2 to be called, and the master trunking service controller TSC1 is in direct connection with the terminal MS1 to be called. Here, it is understood that the number of the terminal MS1 to be called and the number of the terminal MS1 to be called may be plural. In the acquiring call terminal MS1 and the waiting call terminal MS1, the group call may be established through the master trunking service controller TSC1, and the call is established to the waiting call terminal MS1 and MS2, and the waiting call terminal MS1 and MS2 join the group call after receiving the group call request.
In the embodiment shown in fig. 6, on the foregoing basis, the method for group calling based on location further includes:
and the S3A1 and the master trunking service controller TSC1 inform other trunking service controllers TSC2 to send call requests corresponding to the group call to the terminal to be called MS2 corresponding to other trunking service controllers TSC2, so that the terminal to be called MS2 corresponding to other trunking service controllers TSC2 joins the group call. Specifically, when the trunking network side includes at least one trunking service controller, that is, other trunking service controllers TSC2 connected to the master trunking service controller TSC1, it obtains all the terminals to be called MSn through the master trunking service controller TSC1, and it can be understood here that the terminals to be called MSn obtained by the master trunking service controller TSC1 in all the terminal information stored therein may include the terminal to be called MS1 corresponding to the master trunking service controller TSC1 and the terminal to be called MS2 corresponding to the other trunking service controllers TSC2, or obtain the terminals to be called connected thereto through each trunking service controller respectively, that is, obtain the terminal to be called MS1 corresponding thereto through the master trunking service controller TSC1 and obtain the terminal to be called MS2 corresponding thereto through the other trunking service controllers TSC 2. After the terminal to be called is obtained, the master trunking service controller TSC1 may notify other trunking service controllers TSC2 to send a call request corresponding to the group call to the terminal to be called MS2 corresponding to the other trunking service controllers TSC 2. That is, it may send a call request to its corresponding to-be-called terminal MS1 through master trunking service controller TSC1, and meanwhile, know that other trunking service controllers TSC2 send a call request to its corresponding to-be-called terminal MS2, and add corresponding to-be-called terminal MS1 and to-be-called terminal MS2 to the group call.
Optionally, in an embodiment, the obtaining, by the TSC1, reference position information and preset conditions of the calling terminal MS0, and the obtaining, according to the terminal information, a to-be-called terminal that meets the preset conditions in the trunking network includes: position calculation is carried out on the position information of all terminals connected with the master trunking service controller TSC1 and stored with the trunking network side relative to the reference position information through the master trunking service controller TSC1 so as to obtain the terminal meeting the preset condition as a terminal to be called MSn; specifically, when the TSC1 stores all terminal information, it obtains the location information of all terminals, performs location calculation according to the location information and the reference location information of the MS0, and obtains the terminal that meets the preset condition as the terminal MSn to be called, that is, the location calculation process may be performed in the TSC 1.
In another embodiment, the obtaining, by the other trunking service controller TSC2 and the master trunking service controller TSC1, the to-be-called terminals that satisfy the preset condition and respectively correspond to the other trunking service controllers TSC2 and the master trunking service controller TSC1 includes: and respectively carrying out position calculation on the position information of all terminals directly connected with the other trunking service controller TSC2 and the main trunking service controller TSC1 relative to the reference position information to obtain the terminal meeting the preset condition as the terminal to be called. Specifically, the TSC1 and other trunking service controllers in the trunking service controllers, which are connected to the calling terminal MS0, may compare the location information of all terminals directly connected to the TSC1 with the reference location information, and calculate a terminal meeting a preset condition, so as to obtain the terminal to be called MSn.
In the embodiments shown in fig. 7 and fig. 8, on the foregoing basis, a method for group calling based on location of the present invention further includes:
S1B, a master trunking service controller TSC1 which establishes connection between the trunking network side and a calling terminal MS0 receives a group calling request of the calling terminal MS0 and establishes a group calling; S2B, the master trunking service controller TSC1 sends the group call request, the reference position information and the preset conditions of the calling terminal MS0 to the core network; S3B, the core network acquires a terminal to be called corresponding to the core network according to the group call request of the calling terminal MS0, the reference position information and the preset conditions; S4B, the core network sends the group call request of the calling terminal MS0 to the trunking service controller corresponding to the terminal to be called, so as to send the call request corresponding to the group call to the corresponding terminal to be called through the trunking service controller, so that the terminal to be called joins in the group call. Specifically, when trunking service controllers TSC1 and TSC3 on the trunking network side are connected through a core network, calling terminal MS0 initiates a group call based on location information, main trunking service controller TSC1 determines the type of the group call initiated by calling terminal MS0, which can be understood as a group call based on location information, and main trunking service controller TSC1, while establishing the group call, sends the information of calling terminal MS0, such as the calling number of calling terminal MS0, location information, and the corresponding group call to the core network, the core network obtains and determines the location information of all terminals connected therewith, where the determination may include the core network performing relative distance calculation on the location information of calling terminal MS0 and the location information of all other terminals connected therewith, and obtaining the terminal to be called connected with the core network through the core network according to the reference location information and a preset location threshold, the network node may include a terminal to be called TSC1 corresponding to the master TSC1, and may also include other TSCs 3 connected to the core network, where one or more other TSCs 3 may be provided. The core network sends the group call request of the calling terminal MS0 to the trunking service controllers TSC1 and TSC3 corresponding to the terminal to be called, so as to send the call request corresponding to the group call to the respective corresponding terminal to be called MS1 and MS3 through the trunking service controllers TSC1 and TSC3, so that the terminal to be called MS1 and MS3 join the group call.
Further, in some embodiments, the acquiring, by the core network, the terminal to be called corresponding to the core network according to the group call request of the calling terminal MS0, the reference location information, and the preset condition includes: and performing position calculation on the position information of all terminals connected with the core network relative to the reference position information through the core network to acquire the terminal meeting the preset position threshold as the terminal to be called. Specifically, the core network may obtain the GPS location information of the calling terminal MS0 and the GPS location information of other terminals to be called, via its own information processing unit, to perform distance difference calculation in the horizontal direction, and search for terminals that meet the location threshold range, that is, all terminals to be called. The core network uploads the position information of the calling terminal and the position information of all the terminals to be called to the position information processing unit, and the position information processing unit calculates the relative distance between the position of the calling terminal and the position of the terminals to be called. The position information processing unit sends the number of the terminal to be called and the relative distance to the core network, and the core network judges whether the terminal to be called meets the position threshold or the position information processing unit judges whether the relative position and the position threshold are finished and feeds the terminal to be called meeting the position threshold back to the core network. In other embodiments, the acquiring, by the core network, the terminal to be called corresponding to the core network according to the group call request of the calling terminal MS0, the reference location information, and the preset condition includes: the core network sends the position information of all terminals connected with the core network to the position server to calculate the position information so as to acquire the terminal meeting the preset condition as the terminal to be called. Specifically, on the basis of the above, the core network may send the acquired location information to the location server for calculation, where the location information is not limited to the above-mentioned GPS location information. And calculating the position through the position server to acquire the calling terminal.
Further, the presetting of the position threshold includes: the difference value with the reference position information is less than a preset value. It can be understood here that when the calling terminal MS0 initiates a group call request based on location information, the terminal MSn which is located closer to the calling terminal MS0, that is, meets a certain distance requirement, may receive the group call request, i.e., list it in the terminal to be called, so that more emergency situations can be accommodated, and the service time is saved, where the distance, for example, may initiate the group call to the terminal within one kilometer of the square circle of the calling terminal MS 0.
Further, the preset conditions in some embodiments further include: the terminal MSn to be called is in an idle state; in other embodiments, the method further comprises that the current call level of the terminal to be called MSn is lower than the level of the group call; in some further embodiments, the number of the terminals MSn to be called meets the number threshold requirement. Specifically, when determining whether the terminal MSn to be called satisfies the preset condition for accessing to the group call, the working state of the terminal MSn to be called may be determined, for example, when the terminal MSn to be called is in an idle state, it may be determined that it satisfies the condition for joining to the group call, so that the group call command may be sent to the terminal MSn to be called, and the terminal MSn to be called is added to the group call of the calling terminal MS 0. Sometimes, the terminal MSn to be called is in a non-idle state, but the group call request level of the calling terminal MS0 is high, for example, a very serious emergency is encountered, so when determining the state of the terminal MSn to be called, it is necessary to determine the current working level of the terminal MSn to be called, and when the working level of the terminal MSn to be called is low, for example, only one general routine call is performed, the working of the terminal MSn to be called is terminated, and the terminal MSn to be called is added to the group call with high level initiated by the calling terminal MS 0. Sometimes, when the calling terminal MS0 initiates a group call, the trunking network side determines the number of terminals MSn to be called that approximately need to respond according to the level of the group call, and at the same time, the determined number of terminals MSn to be called that satisfy the preset condition is greater than the actual number, then one or more terminals MS0 to be called that are more suitable, for example, the one or more terminals MS0 closest to the calling terminal MS0, are selected to join the group call. Of course, the preset conditions can be combined, including but not limited to the above cases, and can be set reasonably according to actual conditions.
Further, the group call includes any one of an emergency group call, a full call, a pre-empted call, and a high priority call. Specifically, the requirements of the group call may include various existing group calls, which are used according to specific scenarios.
