As shown in FIG. 4, after receiving an authentication request sent by a cluster core network, the authentication center begins to perform the following steps on the cluster terminal. Authentication and authorization:

In step S201, it is determined whether the terminal of the first type has the remote control authority. If the terminal of the first type has the remote control authority, step S202 is performed. If the terminal of the first type does not have the remote control authority, step S209 is performed.

Step S202, determining whether the second type of terminal authorizes the first type of terminal to perform remote control, wherein if the second type of terminal authorizes the first type of terminal to perform remote control, step S203 is performed; if the second type of terminal does not authorize the first type of terminal To perform remote control, step S210 is performed.

Through the description of the above embodiments, those skilled in the art can clearly understand that the method according to the above embodiment can be implemented by means of software plus a necessary general hardware platform, and of course, by hardware, but in many cases, the former is A better implementation. Based on such understanding, the technical solution of the present invention, which is essential or contributes to the prior art, may be embodied in the form of a software product stored in a storage medium (such as ROM/RAM, disk, The optical disc includes a number of instructions for causing a terminal device (which may be a cell phone, a computer, a server, or a network device, etc.) to perform the methods described in various embodiments of the present invention.

The flow of the remote control method of the cluster terminal in the embodiment of the present invention is described in detail below by referring to the interaction between the network elements in the remote control system of the cluster terminal according to the embodiment of the present invention.

FIG. 5 is a flowchart of the remote control request authentication initiated by the first type of terminal according to the embodiment of the present invention. As shown in FIG. 5, the first type of terminal initiates a remote control request in the cluster, and the 501 is on the terminal interface. The remote control object is selected and a remote control request is sent, which carries the identifier of the remote control object. If the current terminal of the first type is in an RRC connection state with the base station, the remote control request is sent to the base station directly through the 503, and the remote control request is transparently transmitted to the cluster core network by the 504 base station; if the current first type of terminal and the base station are in the RRC idle state, The first type of terminal first needs to establish an RRC connection with the base station through 502. The base station transparently transmits the remote control request to the cluster core network through 504 while initializing the UE context. After receiving the remote control request, the cluster core network sends an authentication request to the authentication center through the 505, and the process remotely controls the authentication. The authentication center passes the authentication and authorization decision process, and determines the authentication through 506, that is, allows remote control. After that, the authentication result is returned to the cluster core network through 507. After receiving the authentication result, the cluster core network broadcasts a remote control request in the group through 508.

Optionally, the authentication result obtained after the authentication center performs authentication has two cases: the authentication pass and the authentication fail, as shown in FIG. 5, where the authentication is passed, where the authentication needs to meet the following conditions: The first type of terminal has remote control authority; the second type of terminal operation is remotely controlled by other terminals; the first type of terminal is in the authorization list of the second type of terminal; and the second type of terminal is currently not remotely controlled by other terminals. On the basis of satisfying the above conditions, if no other terminal initiates a remote control request to the second type terminal at the same time, the authentication is passed through 506, and the remote control is run. If there are multiple first-type terminals simultaneously initiating a remote control request for the second-type terminal, the authentication center selects a terminal that can remotely control the second-type terminal by judging the priorities of the plurality of first-type terminals: if multiple If the priorities of the first-class terminals are inconsistent, the terminal with the highest priority is authorized to remotely control the second-type terminal. If the priorities of the multiple first-class terminals are the same, one of the terminals is authorized to remotely control the second type through a random algorithm. The terminal, for the selected terminal, passes the 506 to determine the authentication pass, and runs the remote control.

FIG. 6 is a flowchart of the failure of the remote control request authentication initiated by the first type of terminal according to the embodiment of the present invention. As shown in FIG. 6, 601 to 605 are the same as 501 to 505, and details are not described herein again. When the authentication center determines that the authentication pass condition is not met, it determines that the authentication fails by 606, and does not allow remote control. The authentication center returns the authentication result to the cluster core network through 607. After receiving the authentication result, the cluster core network sends a message to the base station to notify the terminal of the authentication failure and the reason for the failure by using the intra-group broadcast mode, and the base station transparently transmits the foregoing authentication result to the first type terminal through the 609, and ends the remote control process. .

Optionally, when the authentication is passed, the cluster core network determines whether the current group is in the group call process. If it is in the group call right process, the group broadcast downlink bearer is expanded, and the remote control result fed back by the second type terminal is broadcasted on the new broadcast downlink bearer; if not in the group call process, the group context is established. And establish a broadcast downlink bearer for the broadcast of the remote control result.

7 is a flowchart of a second type of terminal responding to a remote control request and returning a remote control result according to an embodiment of the present invention. As shown in FIG. 7, after receiving a remote control request broadcast by the cluster core network, the base station passes the 701 at the base station. The corresponding cell performs a group broadcast remote control request. After receiving the broadcasted remote control message, the second type of terminal parses the request message, and determines, by 702, that the identifier of the remote control object is consistent with its own identity, that is, if it is remotely controlled, responding to the remote control request, and transmitting the remote control through 704. Control results. If the second type of terminal and the base station are in the RRC idle state, it is also required to establish an RRC connection with the base station through 703, and then respond to the remote control request through 704, and feed back the remote control result. The base station transparently transmits the remote control result to the cluster core network through the 705. After receiving the remote control result, the cluster core network performs 706 the remote control result broadcasted in the group by the base station. After responding to the remote control request and feeding back the remote control result, the second type terminal continues to respond to the subsequent remote control request through 707, and feeds back the remote control result to the cluster core network to broadcast in the cluster.
