embodiment one:

fig. 1A shows an implementation flow of a data transmission method for a vertical industry according to an embodiment of the present invention, for convenience of explanation, only a portion related to the embodiment of the present invention is shown, and the details are as follows:

In step S101, the first base station receives first data sent by the first 5G user terminal.

The embodiment of the invention is suitable for the base station side in the 5G communication network, and more particularly, suitable for the base station side in the local sharing network. The local sharing network is composed of a trust server and base stations, 5G user terminals and local user terminals corresponding to all IP addresses in a current IP address mapping table of the trust server, wherein the IP address mapping table comprises corresponding relations among the base stations, the 5G user terminals and the local user terminals, the local user terminals corresponding to the IP addresses in the IP address mapping table are user terminals in the vertical industry, and the trust server can establish communication connection with any base station in the 5G communication network, for example, the local sharing network shown in fig. 1B.

IP of the second base station		IP of the second local user terminal
			IP of third base station	IP of second 5G user terminal

TABLE 1

It should be noted that, if the IP address allocated to the 5G ue, the base station or the local ue is already added to the IP address mapping table, the 5G ue, the base station or the local ue may be considered to have joined the local shared network. The IP address mapping table in the trust server of the local sharing network is dynamically updated, each base station which is added into the local sharing network currently stores the IP address mapping table, and the IP address mapping table in each base station is updated according to the IP address mapping table in the trust server. The trust server manages the local shared network by maintaining the IP address mapping table, and the specific implementation manner of managing the local shared network can refer to the description of the third embodiment, which is not repeated herein. The first base station, the second base station, the first local user terminal and the second local user terminal described in the embodiments of the present invention may be regarded as having joined the local shared network.

In the embodiment of the invention, after the first base station receives the first data sent by the first 5G user terminal, before GTP encapsulation, the first base station searches the destination address of the first data according to the local current IP address mapping table, and if the destination address of the first data is not searched in the current IP address mapping table of the first base station, the first base station sends the first data to the corresponding UPF network element in a GTP encapsulation mode.

In step S102, if the destination address of the first data is included in the current IP address mapping table of the first base station and the destination address of the first data is the IP address allocated to the first local user terminal served by the first base station, the first base station forwards the first data to the first local user terminal through the first local communication module of the first base station.

In the embodiment of the present invention, the first local communication module serves the first local user terminal, and the first local communication module may include a WiFi module and/or bluetooth. After the first base station receives the first data, the first data is sent to the first local communication module, and the first local communication module forwards the first data to the first local user terminal covered by the first local communication module. The data transmission between the 5G user and the local user served by the same base station can be realized without passing through network element equipment such as a core network and the like, so that the data transmission delay is reduced.

Preferably, if the destination address of the first data is included in the current IP address mapping table of the first base station and the destination address of the first data is the IP address allocated to the second local user terminal served by the second base station, the first base station sends the first data to the second base station according to a preset transmission protocol, so that the second base station forwards the first data to the second local user terminal through the second local communication module of the second base station, and as the data transmission from the 5G user served by different base stations to the industry service user can be realized without passing through network element equipment such as a core network, the data transmission delay is further reduced. Specifically, after receiving the first data sent by the first base station, the second base station searches the local current IP address mapping table for the destination address of the first data, and then sends the first data to the second local communication module, and the second local communication module forwards the first data to the second local user terminal covered by the second local communication module. The preset transmission protocol includes GTP or TCP/IP, and the specific implementation manner of the second local communication module may refer to the related description of the first local communication module, which is not described herein. It should be noted here that the second local communication module is the same as or different from the first local communication module.

In the embodiment of the invention, the first base station receives the first data sent by the first 5G user terminal, if the destination address of the first data is contained in the current IP address mapping table of the first base station and the destination address of the first data is the IP address allocated to the first local user terminal served by the first base station, the first base station forwards the first data to the first local user terminal through the first local communication module of the first base station, and as the data transmission from the 5G user served by the same base station to the local user in the vertical industry can be realized without network element equipment such as a core network, the data transmission delay is reduced, the service quality (Quality of Service, qoS for short) is improved, the burden of the 5G network is reduced, and the operation cost is reduced.

Embodiment two:

based on the first embodiment of the present invention, fig. 2 shows a realization flow of a data transmission method for the vertical industry provided by the second embodiment of the present invention, and for convenience of explanation, only the parts related to the first embodiment of the present invention are shown, and the details are as follows:

in step S201, the first base station receives second data sent by the first local user terminal through the first local communication module.

The third base station and the second 5G ue described in the embodiment of the present invention may be regarded as having joined the local shared network described in the embodiment.

In the embodiment of the invention, the first local communication module receives the second data sent by the first local user terminal through WiFi or Bluetooth and the like, and forwards the second data to the first base station.

After receiving the second data sent by the first local user terminal, the first base station retrieves the destination address of the second data according to the local current IP address mapping table, and if the destination address of the second data is not retrieved in the current IP address mapping table of the first base station, the second data is discarded.

In step S202, if the destination address of the second data is included in the current IP address mapping table of the first base station and the destination address of the second data is the IP address allocated to the vertical service of the first 5G ue served by the first base station, the first base station matches the second data to the corresponding DRB bearer allocated to the first 5G ue and sends the second data to the first 5G ue through the air interface.

In the embodiment of the present invention, preferably, if the destination address of the second data is included in the current IP address mapping table of the first base station and the destination address of the second data is the IP address allocated to the vertical industry service of the second 5G ue served by the third base station, the first base station sends the second data to the third base station according to the preset transmission protocol, so that the third base station matches the second data to the corresponding DRB bearer allocated to the second 5G ue, and sends the second data to the second 5G ue through the air interface. The data transmission from the local user served by different base stations to the 5G user can be realized without passing through network element equipment such as a core network and the like, so that the data transmission delay is further reduced. Specifically, after receiving the second data sent by the first base station, the third base station retrieves the IP address allocated to the vertical industry service of the second 5G user terminal from the local current IP address mapping table, and then sends the second data to the second local communication module, and the second local communication module forwards the second data to the second local user terminal covered by the second local communication module.

In the embodiment of the invention, the first base station receives the second data sent by the first local user terminal through the first local communication module, and if the destination address of the second data is contained in the current IP address mapping table of the first base station and the destination address of the second data is the IP address allocated to the vertical industry service of the first 5G user terminal, the first base station matches the second data to the corresponding DRB bearer allocated to the first 5G user terminal and sends the second data to the first 5G user terminal through an air interface, and as the data transmission from the local user to the 5G user in the vertical industry served by the same base station can be realized without network element equipment such as a core network, the data transmission delay is reduced, the service quality is improved (Quality of Service, qoS for short), the burden of the 5G network is reduced, and the operation cost is reduced.

Embodiment III:

fig. 3 shows a flow of implementing a local shared network management according to the third embodiment of the present invention, and for convenience of explanation, only a portion related to the embodiment of the present invention is shown, which is described in detail below:

in step S301, the first base station sends the acquired IP address allocated to the vertical industry service of the first 5G user terminal to the trust server, and stores the received IP address mapping table sent by the trust server.

In the embodiment of the invention, the trust server is used for generating the first update information based on the obtained IP address allocated to the vertical business service of the first 5G user terminal, updating the first update information to the current IP address mapping table of the trust server, sending the updated IP address mapping table to the first base station, and broadcasting the first update information so as to enable the IP address to be synchronously updated in the current IP address mapping tables of all the base stations in the current IP address mapping table of the trust server. The first updating information comprises an IP address of the first base station, an IP address allocated to the vertical industry service of the first 5G user terminal and a corresponding relation between the first base station and the first 5G user terminal.

Specifically, after the first 5G ue joins the 5G communication network, the first base station serving the first 5G ue may differentiate the public network service and the vertical industry service according to the S-nsai (single network slice selection assistance information, single network slice selection auxiliary information) carried in the first 5G ue signaling, acquire and store the IP address allocated to the vertical industry service, and send the acquired IP address allocated to the vertical industry service of the first 5G ue to the trust server, and then the trust server updates the generated first update information to the current IP address mapping table of the trust server, sends the updated IP address mapping table to the first base station, and may broadcast the first update information based on the IP addresses of all the base stations in the IP address mapping table before update. The first base station stores the received IP address mapping table sent by the trust server to the local, if one IP address mapping table is stored in the first base station, the first base station can directly cover the IP address mapping table, and all base stations receiving the first updating information update the first updating information to the local current IP address mapping table so as to ensure the synchronous updating of the base station and the IP address mapping table in the trust server. To this end, the first 5G user terminal may be considered to be joining the local shared network.

In step S302, the first base station sends the information of the first local user terminal acquired through the first local communication module to the trust server, and stores the received IP address mapping table sent by the trust server.

In the embodiment of the invention, the authorization server is further used for authenticating the first local user terminal according to the received information of the first local user terminal, distributing an IP address for the first local user terminal after passing the authentication, generating second update information based on the IP address distributed by the first local user terminal, updating the second update information into the current IP address mapping table of the authorization server, sending the updated IP address mapping table to the first base station, and broadcasting the second update information so that the IP address is synchronously updated in the current IP address mapping tables of all the base stations in the current IP address mapping table of the authorization server, wherein the second update information comprises the IP address of the first base station, the IP address of the first local user terminal and the corresponding relation between the first base station and the first local user terminal.

Specifically, the first base station acquires information of the first local user terminal through the first local communication module, and sends the acquired information to the trust server, wherein the information can be a MAC address or a trusted code. The method comprises the steps that access information of a local user terminal, such as an MAC (media access control) address or a trusted code, is added in advance in a trusted server, the trusted server judges whether the acquired information is contained in the access information, if the acquired information is contained in the access information of the trusted server, the first local user terminal passes authentication, the trusted server distributes an IP (Internet protocol) address for the first local user terminal, and the first local user terminal is added into a local shared network by using the distributed IP address; if the authentication information is not included in the admission information of the trust server, the authentication of the first local user terminal is determined not to pass, and in this case, the trust server does not allocate an IP address to the first local user terminal, and the first local user terminal cannot join the local shared network. And then, the trust server updates the generated second updating information into the current IP address mapping table of the trust server, sends the updated IP address mapping table to the first base station and can broadcast the second updating information based on the IP addresses of all the base stations in the IP address mapping table before updating. The first base station stores the received IP address mapping table sent by the trust server to the local, if one IP address mapping table is stored in the first base station, the first base station can directly cover the IP address mapping table, and all base stations receiving the second updating information update the second updating information to the local current IP address mapping table so as to ensure the synchronous updating of the IP address mapping tables in the base station and the trust server. To this end, the first local user terminal may be considered to be joining the local shared network.

Preferably, when the first base station receives the third updating information broadcast by the trust server, the current IP address mapping table of the first base station is updated according to the third updating information, so that the first base station updates the IP address mapping table in time. The trust server is further configured to generate third update information when the obtained IP address allocated to the vertical industry service of any 5G user terminal in the current IP address mapping table of the trust server or the IP address allocated to any local user terminal needs to be modified or deleted, update the third update information to the current IP address mapping table of the trust server, and broadcast the third update information, so that the IP address is synchronously updated in the current IP address mapping tables of all the base stations included in the current IP address mapping table of the trust server.

Specifically, in a real situation, both the IP address allocated to the vertical industry service of the 5G user terminal and the IP address allocated to the local user terminal may be modified, and the service base stations of the 5G user terminal and the local user terminal may also be changed. Taking the first base station as an example, when the first base station obtains the IP address allocated to the vertical industry service of the first 5G user terminal or the IP address allocated to the first local user terminal needs to be modified or deleted, the first base station may send an IP address change notification to the trusted server, the trusted server may generate third update information according to the received IP address change notification and may broadcast the third update information based on the IP addresses of all the base stations in the IP address mapping table before updating, the base station that receives the third update information updates the third update information to the local IP address mapping table, and the IP address based on the first base station is also included in the current IP address mapping table of the trusted server, so when the first base station receives the third update information, the current IP address mapping table of the first base station is updated according to the third update information. Accordingly, the related information of the gateway corresponding to each base station is also updated synchronously.

In the embodiment of the present invention, the manner of joining the local shared network by any 5G ue in the 5G communication network may refer to the description related to step S301, and the manner of joining the local shared network by any local ue in the vertical industry may refer to the description related to step S302. The order of joining the local shared network by the 5G ue and the local ue is not fixed based on the actual situation, and thus the order of execution of steps S301 and 302 is not fixed.
