To solve this problem, a wireless ad-hoc network (ad-hoc network) is proposed in the prior art. The wireless self-organizing network is a multi-hop mobility peer-to-peer network which is composed of dozens of nodes to hundreds of nodes, adopts a wireless communication mode and is dynamically networked. The wireless ad hoc network does not need to be supported by fixed equipment, each node (such as a target terminal) is automatically networked, and the wireless ad hoc network can be deployed quickly, conveniently and efficiently and is suitable for the communication needs of some emergency occasions.

However, the existing wireless ad hoc network employs a short-range wireless communication protocol between nodes, so that the wireless ad hoc network has a limited delivery range.

That is, the dynamic mobile network is permitted to be used only when the condition for permitting the dynamic mobile network to be used is satisfied, so that it is possible to prevent the dynamic mobile network from possibly causing interference to the macro network.

For example, the condition allowed to be used by the dynamic mobile network may include one or more of an area allowed to be used by the dynamic mobile network or a time period allowed to operate independently by the dynamic mobile network, which is not specifically limited in the embodiment of the present application.

Optionally, in this embodiment of the present application, for the dynamic mobile network, it may not need to have its own independent subscription data in the HSS or the UDM network element like a macro network of an operator, but may configure a public subscription data in the mobile core network device, where the public subscription data is effective for the terminal accessing the dynamic mobile network, so as to save a storage space of the core network device.

S903, optionally, the management device sends the information of the application to the mobile server, so that the mobile server receives the information of the application from the management device.

Wherein the information of the application is used to configure the application on the mobile server.

It should be noted that step S901, step S902, and step S903 in the embodiment of the present application provide a configuration process of a dynamic mobile network. The three steps do not have a necessary execution sequence, any one or two of the three steps may be executed first, and then the remaining steps are executed, or the three steps may be executed simultaneously, which is not specifically limited in this embodiment of the present application.

Optionally, the dynamic networking method provided in this embodiment of the present application may further include a stage of activating an access device function that the mobile access device has.

In a first manner, in a possible implementation manner, the stage of activating the access device function that the mobile access device has provided in the embodiment of the present application is as shown in steps S904a-S905 a:

s904a, the mobile access device determines that the conditions allowed by the dynamic mobile network are satisfied.

Illustratively, the mobile access device determines that the condition for allowing the dynamic mobile network to be used is satisfied, including: the mobile access equipment determines that the current position of the mobile access equipment is in an area allowed to be used by the dynamic mobile network; alternatively, the mobile access device determines that the current time is within a time period that the dynamic mobile network is allowed to operate independently.

Of course, in this embodiment of the present application, the condition that the mobile access device determines that the dynamic mobile network is allowed to use is satisfied, or the mobile access device may determine that the current location of the mobile access device is within an area that the dynamic mobile network is allowed to use, and the mobile access device determines that the current time is within a time period that the dynamic mobile network is allowed to operate independently, that is, the location and the time are satisfied at the same time, which is not specifically limited in this embodiment of the present application.

The mobile access device may locate the current location of the mobile access device according to a Global Positioning System (GPS) or a beidou positioning function of the mobile access device, which is not specifically limited in this embodiment of the present application.

S905a, the mobile access device activates an access device function of the mobile access device.

In this embodiment of the present application, the access device functions of the mobile access device may include, for example, a signal transceiving function of an air interface, and related descriptions may refer to an existing implementation manner and are not described herein again.

Optionally, in this embodiment of the application, if the access device functions of the mobile access device are already in operation and are in an operating state, but the access device functions are set to an inactive state, so that the access device functions cannot send the radio broadcast information and cannot process the received message, in this scenario, the "access device functions that the mobile access device activates" specifically include: the mobile access equipment sets the state of the access equipment function of the mobile access equipment to be an activated state, and then the access equipment function can send wireless broadcast information and process received messages.

Or, in this embodiment of the application, if the access device function of the mobile access device is not in operation and is in a non-operating state, in this scenario, the "activating, by the mobile access device, the access device function of the mobile access device" specifically includes: the mobile access device has an access device function which is in an operation activation state, and further, the access device function can send wireless broadcast information and process received messages.

The embodiment of the present application does not specifically limit how the mobile access device activates the access device function that the mobile access device has.

In a second mode, another possible implementation manner, the stages for activating the access device function of the mobile access device provided in the embodiment of the present application are as shown in steps S904b-S908 b:

s904b, the mobile access device determines a current location of the mobile access device.

The step S904a may be referred to as a manner of determining the current location of the mobile access device by the mobile access device, which is not described herein again.

S905b, the mobile access device sends the current location information of the mobile access device to the mobile core network device, so that the mobile core network device receives the current location information of the mobile access device from the mobile access device.

S906b, the mobile core network device determines that the current location of the mobile access device is within the area allowed to be used by the dynamic mobile network.

S907b, the mobile core network device sends a notification message to the mobile access device, so that the mobile access device receives the notification message from the mobile core network device. The notification message is used for notifying the mobile access equipment to activate the access equipment function of the mobile access equipment.

Optionally, in this embodiment of the application, the mobile core network device may further send the notification message to the mobile access device when it is determined that the current location of the mobile access device is within an area allowed to be used by the dynamic mobile network and the current time is within a time period allowed by the dynamic mobile network to operate independently, which is not specifically limited in this embodiment of the application.

S908b, the mobile access device activates the access device function of the mobile access device according to the notification message.

In a third mode and another possible implementation manner, the stages for activating the access device function of the mobile access device provided by the embodiment of the present application are as shown in steps S904c-S908 b:

s904c, the mobile core network device determines that the condition allowed by the dynamic mobile network is satisfied.

For example, the mobile core network device determines that the condition allowed to be used by the dynamic mobile network is satisfied, including: the mobile core network equipment determines that the current position of the mobile core network equipment is in an area allowed to be used by the dynamic mobile network; or, the mobile core network device determines that the current time is within a time period allowed by the dynamic mobile network to operate independently.

The mobile core network device may locate the current position of the mobile core network device according to a GPS or a beidou positioning function that the mobile core network device has, which is not specifically limited in the embodiment of the present application.

Of course, in this embodiment of the present application, the condition that the mobile core network device determines that the dynamic mobile network allows use is satisfied, or the mobile core network device may determine that the current location of the mobile core network device is within an area that the dynamic mobile network allows use, and the mobile core network device determines that the current time is within a time period that the dynamic mobile network allows independent work, that is, the location and the time are satisfied at the same time.

S905c, the mobile core network device sends a notification message to the mobile access device, so that the mobile access device receives the notification message from the mobile core network device. The notification message is used for notifying the mobile access equipment to activate the access equipment function of the mobile access equipment.

S906c, the mobile access equipment activates the access equipment function of the mobile access equipment according to the notification message.

After the access device function of the mobile access device is activated, the dynamic networking method provided in this embodiment of the present application may further include the following terminal access and authentication phases (it may be understood that there are one or more terminals in the network, and the following description is given by taking only a first terminal corresponding to the first terminal identifier in the terminal identifier list and a second terminal corresponding to the second terminal identifier as an example):

s909a, the mobile access device sends the wireless broadcast information to the first terminal, so that the first terminal receives the wireless broadcast information from the mobile access device.

The radio broadcast information includes air interface configuration information of a macro network to which the dynamic mobile network belongs, and is used for one or more terminals to access the dynamic mobile network.

S910a, the first terminal selects the mobile access device in fig. 9a according to the radio broadcast information, and establishes a Radio Resource Control (RRC) connection with the mobile access device.

After the mobile access device sends the wireless broadcast information, because the wireless broadcast information includes the air interface configuration information of the macro network to which the dynamic mobile network belongs, the first terminal can seamlessly access to the dynamic mobile network device without any modification or customization, and can seamlessly connect to the macro network of the operator.

For a specific implementation of establishing the RRC connection between the first terminal and the mobile access device, reference may be made to an existing implementation manner, which is not described herein again.

S911a, the first terminal sends the access request message to the mobile core network device through the mobile access device, so that the mobile core network device receives the access request message from the first terminal.

For example, for a 2G network, a 3G network, a 4G network, or a 4.5G network, the access request message may be, for example, an attach request (attach request) message; for the 5G network, the access request message may be, for example, a registration request (registration request) message, where the access request message is used to request to access the dynamic mobile network, and this is not limited in this embodiment of the present invention.

S912a, the mobile core network device determines that the first terminal is within the range of the terminal allowed to use the dynamic mobile network according to the information of the terminal identifier list of the terminal allowed to use the dynamic mobile network, and then accepts the access request of the first terminal.

Optionally, considering that the deployment of the dynamic mobile network is mainly for processing emergency services such as rescue, search and rescue, the network side simplifies the processing and may not perform the authentication process of the terminal. Therefore, in the embodiment of the present application, the mobile core network device may only execute the authentication procedure of the first terminal without executing the authentication procedure of the first terminal. Of course, if the first terminal is not in the range of the terminal allowed to be used by the dynamic mobile network, the mobile core network device may reject the first terminal to access the dynamic mobile network, which is not specifically limited in this embodiment of the present application.

S913a, optionally, the mobile core network device initiates a session establishment procedure of the first terminal according to the public subscription data.

Exemplarily, if the first terminal accesses the dynamic mobile network through the 4G network or the 4.5G network, the PDN connection corresponding to the first terminal may be established through the PDN connection establishment procedure initiated by the first terminal after the attach procedure is ended; if the first terminal accesses the dynamic mobile network through the 5G network, a Packet Data Unit (PDU) session establishment procedure initiated by the first terminal may be used to establish a PDU session corresponding to the first terminal after the registration procedure is completed.

Optionally, the actions of the mobile core network device in steps S912a and S913a in this embodiment may be specifically executed by a mobility management function module in the mobile core network device, such as an AMF module in a 5G network, an MME module in a 4G network or a 4.5G network, or an SGSN module in a 2G network or a 3G network, which is not specifically limited in this embodiment of the application.

S914a, the mobile core network device sends an access accept message to the first terminal through the mobile access device, so that the first terminal receives the access accept message from the mobile core network device.

Wherein the access accept message is used to indicate that the first terminal has been allowed to access the dynamic mobile network.

For example, for a 2G network, a 3G network, a 4G network, or a 4.5G network, the access accept message may be, for example, an attach accept (attach accept) message; for the 5G network, the access accept message may be, for example, a registration accept (registration accept) message, which is not specifically limited in this embodiment of the present application.

S909b-S914b are similar to S909a-S914a, except that the first terminal in steps S909a-S914a is replaced by the second terminal in steps S909b-S914b, and the related description can refer to steps S909b-S914b, which are not repeated herein.

On the one hand, based on the dynamic networking method provided by the embodiment of the application, a dynamic mobile network can be deployed in a blind area covered by a macro network of some operators, and the dynamic mobile network can realize seamless docking and intercommunication with the macro network by performing supplementary coverage on the macro network, so that a target terminal can safely access the dynamic mobile network according to the macro network mode of the operators under the condition that the target terminal does not need to be modified or customized.

The actions of the mobile access device or the mobile core network device in steps S901 to S914b may be executed by the processor 801 in the communication device 800 shown in fig. 8 calling the application program code stored in the memory 803, which is not limited in this embodiment.

Based on the dynamic networking method shown in fig. 9a, optionally, the dynamic networking method provided in this embodiment of the present application may further include a local data communication phase shown in fig. 9b (it can be understood that one or more terminals exist in the network, and the following description is given only by taking local data communication between the first terminal and the second terminal as an example), including the following steps:

s915, the mobile core network device establishes local routing information, where the local routing information includes information of downlink paths corresponding to one or more terminals corresponding to the terminal identifier list.

For example, the established local routing information may be as shown in table one, and includes information of a terminal identifier and a corresponding downlink path:

watch 1

Terminal identification	Information of downlink path
		First terminal identification	Information 1 of downlink path
Second terminal identification	Information			2 of downlink path
		Third terminal identification	Information 3 of the downstream path
……	……

In the embodiment of the present application, the downlink path information corresponding to a certain terminal is used for the mobile core network device to send a received data packet carrying address information of the terminal to the terminal. For example, the downlink path information 1 corresponding to the first terminal is used for the mobile core network device to send a received third data packet to the first terminal, where the third data packet carries address information of the first terminal; the downlink path information 2 corresponding to the second terminal is used for the mobile core network device to send the received first data packet to the second terminal, wherein the first data packet carries address information of the second terminal; the downlink path information 3 corresponding to the third terminal is used for the mobile core network device to send a received fourth data packet to the third terminal, where the fourth data packet carries address information of the third terminal, and so on, which is not illustrated here,

optionally, in this embodiment of the present application, the downlink path information corresponding to a certain terminal may include, for example, an address of the mobile access device and a tunnel identifier allocated by the mobile access device to the terminal, which is not specifically limited in this embodiment of the present application. For example, the address of the mobile access device may be, for example, an Internet Protocol (IP) address between networks, and the tunnel identifier allocated by the mobile access device to the terminal may be, for example, a Tunnel Endpoint Identifier (TEID), and the like, which is not specifically limited in this application.

S916, optionally, the mobile core network device establishes a local routing policy, where the local routing policy includes address information of a local application used by one or more terminals corresponding to the allowed terminal identifier list.

The local application information allowed to be used by the first terminal is used for the mobile core network equipment to send the received second data packet from the first terminal to the mobile server corresponding to the local application allowed to be used by the first terminal.

For example, the established local routing policy may be as shown in table two, and includes an application identifier and address information of a corresponding application:

watch two

Application identification	Address information of applications
		Identification of a first application	Address information 1
Identification of a second application	Address information			2
		Identification of third application	Address information 3

Taking the example that the first terminal sends the data packet 1 to the second terminal, in a possible implementation manner, the data communication manner provided by the embodiment of the present application is as shown in steps S917a-S919 a:

s917a, the first terminal sends the data packet 1 to the mobile core network device through the mobile access device, so that the mobile core network device receives the data packet 1 from the first terminal.

Wherein, the data packet 1 carries the address information of the second terminal.

Optionally, the data packet 1 may further carry an identifier of a first application that is allowed to be used by the first terminal, where the first application may be, for example, a local voice application or a local video application, and this is not specifically limited in this embodiment of the present application.

S918a, the mobile core network device determines the information of the downlink path corresponding to the second terminal according to the local routing information.

Specifically, after receiving the data packet 1, the mobile core network device may obtain, according to destination address information (i.e., address information of the second terminal) in the data packet 1, that the data packet 1 is to be sent to the second terminal, and then the mobile core network device may query the local routing information to obtain information of a downlink path corresponding to the second terminal. For example, if the established local routing information is shown in table one, the information of the downlink path corresponding to the second terminal may be information 2 of the downlink path.

S919a, the mobile core network device sends, according to the information of the downlink path corresponding to the second terminal, the data packet 1 to the second terminal through the mobile access device, so that the second terminal receives the data packet 1 from the mobile core network device.

Or, taking the first terminal sending the data packet 1 to the second terminal as an example, in another possible implementation manner, if the step S916 is executed and the data packet 1 may further carry an identifier of the first application that is allowed to be used by the first terminal, the data communication manner provided in the embodiment of the present application may be as shown in steps S917b-S921 b:

Specifically, after receiving the data packet 1, the mobile core network device may query the local routing policy according to an identifier of a first application that is allowed to be used by the first terminal and carried in the data packet 1, so as to obtain address information corresponding to the first application. For example, if the established local routing policy is shown in table two, the address information corresponding to the first application may be address information 1.

S919b, the mobile core network device sends, according to the address information corresponding to the first application, the data packet 1 to the mobile server corresponding to the first application, so that the mobile server corresponding to the first application receives the data packet 1 from the mobile core network device.

S920b, the mobile server processes the packet 1 to obtain a packet 2. The data packet 2 carries address information of the second terminal.

S921b, the mobile server sends the data packet 2 to the mobile core network device, so that the mobile core network device receives the data packet 2 from the mobile server 2.

S922b-S923b are similar to steps S918a-S919a, for example, the difference is that in this embodiment of the application, the data packet 1 in steps S918a-S919a is replaced by the data packet 2, and related descriptions may refer to steps S918a-S919a, which are not described herein again.

Specifically, three points of the airborne mobile access equipment can move in the target area, longitude and latitude position information of the three points of the airborne mobile access equipment is obtained, and the distance of the airborne mobile access equipment to the terminal is measured and calculated at the three points, so that the airborne mobile access equipment can calculate accurate longitude and latitude position information of the terminal based on a positioning algorithm.
