The memory 1005 may also optionally be a storage device separate from the processor 1001 described above.
It will be appreciated by those skilled in the art that the device architecture shown in fig. 1 is not limiting as to the interconnection of devices with private network terminals under a base station, and may include more or fewer components than shown, or may combine certain components, or may have a different arrangement of components.
As shown in fig. 1, the memory 1005, which is a storage medium, may include an operating system, a network communication module, a user interface module, and an interconnection program with a private network terminal under a base station.
In the private network terminal interconnection device under the same base station shown in fig. 1, the network interface 1004 is mainly used for connecting to an external network and performing data communication with other network devices; the user interface 1003 is mainly used for connecting user equipment and communicating data with the user equipment; the device of the present invention invokes the interconnection program of the private network terminal under the same base station stored in the memory 1005 through the processor 1001, and executes the interconnection method of the private network terminal under the same base station provided by the embodiment of the present invention.
Based on the hardware structure, the embodiment of the invention provides an interconnection method of private network terminals under the same base station.
Referring to fig. 2, fig. 2 is a flowchart of a first embodiment of a private network terminal interconnection method under the same base station according to the present invention.
In a first embodiment, the method for interconnecting private network terminals under the same base station includes:
and step S10, when the access service flow sent by the first terminal is received, determining a second terminal according to the access service flow.
It should be noted that, the execution body of the embodiment may be a private network terminal interconnection device under the same base station, and the device may be a base station device with a data processing function, or may be other devices that may implement the same or similar functions, which is not limited in this embodiment, and in this embodiment, the base station device is taken as an example for illustration.
It should be noted that, in this embodiment, the private network terminal refers to a terminal under the same private network, which is not limited in this embodiment. The private network in this embodiment may be equivalent to a local area network, which is not limited in this embodiment.
It should be understood that as the 5G technology gradually matures and the standard of the 6G technology is continuously established, the objective of everything interconnection is further achieved in the late 5G age and the 6G age. In the current 5G age, more emphasis is still placed on direct interconnection of objects with people, and in the 6G age, more centers of gravity are placed on direct interconnection of objects with people. In order to realize direct connection between objects, communication between current private network terminals is wound into a core network mainly through a wireless network, and finally reaches a user switch or a server to realize interaction, so that the link distance is long and the number of intermediate network elements is large. The terminal under the base station cannot directly communicate, so that the traditional communication mode is required, and millisecond-level everything interconnection cannot be realized.
Therefore, the current method for interconnecting with the private network terminal under the base station has the following defects: 1. the same private network user under the same base station needs to bypass through a user side exchanger, so that a transmission link is long; 2. high-speed transmission with large bandwidth cannot be formed and is severely limited by the bandwidth of a user side; 3. the large-scale transmission of data between terminals increases the uplink and downlink traffic load of the base station.
It should be noted that, in this embodiment, the base station apparatus may be provided with a baseband processing unit (BBU), which is not limited in this embodiment. Referring to fig. 3, fig. 3 is a schematic block diagram of a BBU, and according to this embodiment, by adding a terminal interconnection module at the BBU, service identification, data interconnection and traffic charging of different terminals corresponding to the same private network under the same base station are implemented, so that efficient transmission of terminal interconnection under the same base station is implemented. The terminal interconnection module is used for receiving the private network VPN instance information, and the private network VPN instance information is transmitted to the terminal interconnection module through the private network VPN instance information.
It should be understood that, referring to fig. 4, fig. 4 is a schematic module interaction diagram, which illustrates a method flow of identifying, determining and forwarding with a private network terminal under a base station, where a terminal interconnection module mainly relates to a service identification module, a service determination module, a service forwarding module and a traffic charging module. The service identification module is positioned in the terminal interconnection module, and can identify all the same private network terminals under the base station through VPN instance information, including the IP addresses of the private network terminals; the service judging module is positioned in the main control transmission unit, judges the destination address and the source address through the same private network terminal in the VPN instance, confirms whether the data packet needs to be sent to the corresponding destination address under the same base station and the same VPN instance, and establishes a bidirectional data session if the data packet is confirmed to be forwarded so as to reduce judging times; the service forwarding module is positioned in the main control transmission unit, and the data packet to be forwarded is forwarded to the corresponding destination address by the service forwarding module, so that the bidirectional data session can be continuously updated, and the flow statistical data is reported to the flow charging module; the flow charging module is positioned in the terminal interconnection module, charges the terminal using flow according to the flow statistical data of the service forwarding module, and periodically uploads the flow to the core network for charging and settlement.
In a specific implementation, the following description will be given by taking the data interconnection of the a terminal and the B terminal under the same base station as an example:
STEP1: the AB terminal accesses the wireless network through the same baseband processing unit, and the service identification module identifies VPN instance information of the private network and the IP address of the terminal;
STEP2: and the A terminal actively initiates the service flow of the access B terminal, and the service judging module confirms that the flow is private network flow and the address is the IP address of the B terminal, so that a bidirectional data session is established and the service forwarding module forwards the data packet.
STEP3: the data packet of the terminal A arrives at the terminal B, the terminal B returns the packet to the service forwarding module, and the service forwarding module inquires the existing session and directly forwards the session to the terminal A;
STEP4: and the flow billing module receives the flow statistical data from the service forwarding module after the session is ended, and periodically uploads the flow statistical data to the core network billing network element for billing settlement.
It should be understood that, when receiving the access traffic sent by the first terminal, the base station apparatus may determine, according to information related to the access traffic, to which terminal the first terminal needs to send the access traffic, thereby determining the second terminal. The "first" and "second" in this embodiment are only for convenience of distinguishing different objects, and are not limited otherwise.
Step S20, when the second terminal and the first terminal are in the same private network under the base station, establishing a bidirectional data session between the first terminal and the second terminal.
It should be understood that, after determining the second terminal, the base station device may further detect whether the second terminal is under the current base station, and when the second terminal is under the current base station, may further determine whether the second terminal is under the same private network as the first terminal, so as to determine whether the second terminal is under the same private network as the first terminal in the above manner, which is not limited in this embodiment.
It can be appreciated that if the second terminal and the first terminal are in the same private network under the base station, it is indicated that the second terminal and the first terminal belong to the private network terminal under the same base station, and therefore, in order to implement efficient interconnection transmission between the second terminal and the first terminal, a bidirectional data session between the first terminal and the second terminal may be established.
It can be understood that if the second terminal and the first terminal are not in the same private network under the base station, it is indicated that the second terminal and the first terminal do not belong to the private network terminal under the same base station, so the access traffic sent by the first terminal may still be processed in the original manner, which is not limited in this embodiment.
Further, in order to more quickly and accurately establish a bidirectional data session between a first terminal and a second terminal, the establishing the bidirectional data session between the first terminal and the second terminal includes: generating a first session end according to a first IP address corresponding to the first terminal; generating a second session end according to a second IP address corresponding to the second terminal; and establishing a bidirectional data session between the first terminal and the second terminal according to the first session end and the second session end.
It should be understood that, in this embodiment, the bidirectional data session may be established according to the first terminal information corresponding to the first terminal and the second terminal information corresponding to the second terminal, where the first terminal information may include, but is not limited to, a first IP address, and the second terminal information may include, but is not limited to, a second IP address.
It may be understood that, in this embodiment, taking terminal information as an IP address for example, a first session end may be generated according to a first IP address corresponding to a first terminal, and a second session end may be generated according to a second IP address corresponding to a second terminal, so as to construct a data transmission channel between the first session end and the second session end, thereby establishing a bidirectional data session between the first terminal and the second terminal.
It should be noted that, one terminal may simultaneously maintain a bidirectional data session with a plurality of other terminals, that is, the plurality of bidirectional data sessions may not interfere with each other, which is not limited in this embodiment.
And step S30, data interconnection between the first terminal and the second terminal is carried out through the bidirectional data session.
It should be understood that after the bidirectional data session between the first terminal and the second terminal is established, the data interconnection between the first terminal and the second terminal can be performed through the bidirectional data session, and through the interaction between the terminal interconnection module and the master control transmission unit, the data forwarding and the traffic statistics between different private network terminals under the same base station can be realized locally at the terminal, so that the transmission link is shortened, the transmission efficiency is improved, and the uplink and downlink traffic load of the base station is also lightened.
Therefore, the scheme solves the problem that the terminal interview under the same base station bypasses through the core network, realizes the rapid termination of the data flow through the internal forwarding of the local BBU, and improves the data transmission efficiency of the private network terminal under the same base station.
In this embodiment, when an access service flow sent by a first terminal is received, a second terminal is determined according to the access service flow; when the second terminal and the first terminal are in the same private network under a base station, establishing a bidirectional data session between the first terminal and the second terminal; and carrying out data interconnection between the first terminal and the second terminal through the bidirectional data session. When the second terminal and the first terminal are determined to be in the same private network under the base station, a bidirectional data session between the two terminals is established to perform data interconnection, so that the data transmission efficiency of the private network terminal under the same base station is improved, and the interconnection high-efficiency transmission of the private network terminal under the same base station is realized.
In an embodiment, as shown in fig. 5, a second embodiment of the method for interconnecting private network terminals under a base station according to the present invention is provided based on the first embodiment, and before the step S20, the method further includes:
and step S01, when the access service flow is private network flow, acquiring current instance information corresponding to the access service flow and a second IP address corresponding to the second terminal.
It should be understood that, since the access traffic sent by the first terminal is not necessarily private network traffic, but the scheme aims at data interconnection of the private network terminals, before performing the subsequent processing flow, it may also be determined whether the access traffic is private network traffic. If the access traffic is private network traffic, the step of determining the second terminal according to the access traffic may be performed, and if the access traffic is not private network traffic, the access traffic sent by the first terminal may still be processed in the original manner, which is not limited in this embodiment.
It should be understood that, in this embodiment, it may be determined whether the second terminal and the first terminal are in the same private network under the base station by combining the instance information and the IP address, where the instance information in this embodiment may include, but is not limited to, VPN instance information, which is not limited to this embodiment.
It can be understood that, in the case where the access service flow is private network flow, current instance information corresponding to the access service flow may be obtained, and a second IP address corresponding to the second terminal may also be obtained.
Step S02, judging whether the second terminal and the first terminal are in the same private network under the base station according to the current instance information and the second IP address.
It should be noted that, when detecting that a plurality of terminals access to a wireless network through a unified baseband processing unit, the service identification module may identify instance information corresponding to the terminals and IP addresses corresponding to the terminals, and then may establish an IP address set according to the IP addresses corresponding to the terminals, and generate a correspondence between the IP address set and the instance information, so as to determine a set of to-be-selected IP addresses according to the current instance information and the correspondence.
It should be understood that after the set of candidate IP addresses is determined in the above manner, whether the set of candidate IP addresses includes the second IP address may be further detected, so as to determine whether the second terminal and the first terminal are in the same private network under the base station according to the detection result.
It can be understood that if the detection result is that the set of the to-be-selected IP addresses includes the second IP address, it is indicated that the second terminal and the first terminal are in the same private network under the base station; if the detection result is that the set of the to-be-selected IP addresses does not contain the second IP address, the second terminal and the first terminal are not in the same private network under the base station.
In a specific implementation, for example, when detecting that an a terminal and a B terminal access to a wireless network through the same baseband processing unit, corresponding a instance information and IP addresses corresponding to the a terminal and the B terminal may be identified, a set of to-be-selected IP addresses is established according to the IP addresses corresponding to the a terminal and the B terminal, and the set of to-be-selected IP addresses is associated with the a instance information. In the above processing procedure, if the second terminal is the B terminal and the current instance information is the a instance information, it may be detected whether the IP address corresponding to the B terminal exists in the set of candidate IP addresses corresponding to the a instance information, and if so, it is indicated that the a terminal and the B terminal are in the same private network under the base station.
In this embodiment, when the access service flow is private network flow, current instance information corresponding to the access service flow and a second IP address corresponding to the second terminal are obtained, and whether the second terminal and the first terminal are in the same private network under the base station is determined according to the current instance information and the second IP address, so that whether the second terminal and the first terminal are in the same private network under the base station can be accurately determined by combining the instance information and the IP address, and a better private network terminal interconnection effect can be achieved.
In an embodiment, as shown in fig. 6, a third embodiment of the method for interconnecting private network terminals under a base station according to the present invention is provided based on the first embodiment or the second embodiment, in this embodiment, the step S30 is described based on the first embodiment, and includes:
and step S301, forwarding the access service flow to the second terminal through the bidirectional data session, and maintaining the bidirectional data session.
It will be appreciated that after establishing a bi-directional data session between the first terminal and the second terminal, access traffic may be forwarded to the second terminal over the bi-directional data session and the bi-directional data session continuously updated to maintain the bi-directional data session.
It can be understood that in the process of forwarding the traffic, the traffic can be counted, and the traffic statistic data is reported to the traffic charging module, which is not limited in this embodiment.
Step S302, when feedback traffic information sent by the second terminal is received, forwarding the feedback traffic information to the first terminal through the bidirectional data session.
It should be understood that, while maintaining the bidirectional data session, the data traffic of the first terminal and the second terminal may also be continuously monitored, when feedback traffic information sent by the second terminal is received, the feedback traffic information is forwarded to the first terminal through the bidirectional data session, and if traffic information sent by the first terminal and/or the second terminal is received again, the traffic information is forwarded to the other terminal.
It should be noted that, there may be a case where the data interconnection between the first terminal and the second terminal is completed, and the bidirectional data session is continuously maintained, which results in wasting resources. Therefore, the preset time period may be set in advance according to the actual situation, and if the traffic information sent by the first terminal and/or the second terminal is not received within the preset time period, the bidirectional data session between the first terminal and the second terminal is ended.
It can be understood that the flow data forwarded in the data interconnection process through the bidirectional data session can be counted to obtain flow statistic data, and charging settlement can be performed according to the flow statistic data.
In a specific implementation, the flow value can be determined according to the flow statistical data, the corresponding flow price is obtained, and charging settlement is performed according to the flow value and the flow price.
In this embodiment, the access service traffic is forwarded to the second terminal through the bidirectional data session, and the bidirectional data session is maintained, and when feedback traffic information sent by the second terminal is received, the feedback traffic information is forwarded to the first terminal through the bidirectional data session, so that data forwarding and traffic statistics between the first terminal and the second terminal can be performed by maintaining the bidirectional data session, and further data transmission efficiency is improved.
In addition, the embodiment of the invention also provides a storage medium, wherein the storage medium stores a private network terminal interconnection program under the same base station, and the private network terminal interconnection program under the same base station realizes the steps of the private network terminal interconnection method under the same base station when being executed by a processor.
Because the storage medium adopts all the technical schemes of all the embodiments, the storage medium has at least all the beneficial effects brought by the technical schemes of the embodiments, and the description is omitted here.
In addition, referring to fig. 7, the embodiment of the present invention further provides an interconnection apparatus of private network terminals under the same base station, where the interconnection apparatus of private network terminals under the same base station includes:
and the service receiving module 10 is used for determining the second terminal according to the access service flow when the access service flow sent by the first terminal is received.
It should be noted that, in this embodiment, the private network terminal refers to a terminal under the same private network, which is not limited in this embodiment. The private network in this embodiment may be equivalent to a local area network, which is not limited in this embodiment.
It should be understood that as the 5G technology gradually matures and the standard of the 6G technology is continuously established, the objective of everything interconnection is further achieved in the late 5G age and the 6G age. In the current 5G age, more emphasis is still placed on direct interconnection of objects with people, and in the 6G age, more centers of gravity are placed on direct interconnection of objects with people. In order to realize direct connection between objects, communication between current private network terminals is wound into a core network mainly through a wireless network, and finally reaches a user switch or a server to realize interaction, so that the link distance is long and the number of intermediate network elements is large. The terminal under the base station cannot directly communicate, so that the traditional communication mode is required, and millisecond-level everything interconnection cannot be realized.
Therefore, the current method for interconnecting with the private network terminal under the base station has the following defects: 1. the same private network user under the same base station needs to bypass through a user side exchanger, so that a transmission link is long; 2. high-speed transmission with large bandwidth cannot be formed and is severely limited by the bandwidth of a user side; 3. the large-scale transmission of data between terminals increases the uplink and downlink traffic load of the base station.
It should be noted that, in this embodiment, the base station apparatus may be provided with a baseband processing unit (BBU), which is not limited in this embodiment. Referring to fig. 3, fig. 3 is a schematic block diagram of a BBU, and according to this embodiment, by adding a terminal interconnection module at the BBU, service identification, data interconnection and traffic charging of different terminals corresponding to the same private network under the same base station are implemented, so that efficient transmission of terminal interconnection under the same base station is implemented. The terminal interconnection module is used for receiving the private network VPN instance information, and the private network VPN instance information is transmitted to the terminal interconnection module through the private network VPN instance information.
It should be understood that, referring to fig. 4, fig. 4 is a schematic module interaction diagram, which illustrates a method flow of identifying, determining and forwarding with a private network terminal under a base station, where a terminal interconnection module mainly relates to a service identification module, a service determination module, a service forwarding module and a traffic charging module. The service identification module is positioned in the terminal interconnection module, and can identify all the same private network terminals under the base station through VPN instance information, including the IP addresses of the private network terminals; the service judging module is positioned in the main control transmission unit, judges the destination address and the source address through the same private network terminal in the VPN instance, confirms whether the data packet needs to be sent to the corresponding destination address under the same base station and the same VPN instance, and establishes a bidirectional data session if the data packet is confirmed to be forwarded so as to reduce judging times; the service forwarding module is positioned in the main control transmission unit, and the data packet to be forwarded is forwarded to the corresponding destination address by the service forwarding module, so that the bidirectional data session can be continuously updated, and the flow statistical data is reported to the flow charging module; the flow charging module is positioned in the terminal interconnection module, charges the terminal using flow according to the flow statistical data of the service forwarding module, and periodically uploads the flow to the core network for charging and settlement.
In a specific implementation, the following description will be given by taking the data interconnection of the a terminal and the B terminal under the same base station as an example:
STEP1: the AB terminal accesses the wireless network through the same baseband processing unit, and the service identification module identifies VPN instance information of the private network and the IP address of the terminal;
STEP2: and the A terminal actively initiates the service flow of the access B terminal, and the service judging module confirms that the flow is private network flow and the address is the IP address of the B terminal, so that a bidirectional data session is established and the service forwarding module forwards the data packet.
STEP3: the data packet of the terminal A arrives at the terminal B, the terminal B returns the packet to the service forwarding module, and the service forwarding module inquires the existing session and directly forwards the session to the terminal A;
STEP4: and the flow billing module receives the flow statistical data from the service forwarding module after the session is ended, and periodically uploads the flow statistical data to the core network billing network element for billing settlement.
It should be understood that, when receiving the access traffic sent by the first terminal, the base station apparatus may determine, according to information related to the access traffic, to which terminal the first terminal needs to send the access traffic, thereby determining the second terminal. The "first" and "second" in this embodiment are only for convenience of distinguishing different objects, and are not limited otherwise.

It can be appreciated that if the second terminal and the first terminal are in the same private network under the base station, it is indicated that the second terminal and the first terminal belong to the private network terminal under the same base station, and therefore, in order to implement efficient interconnection transmission between the second terminal and the first terminal, a bidirectional data session between the first terminal and the second terminal may be established.
It can be understood that if the second terminal and the first terminal are not in the same private network under the base station, it is indicated that the second terminal and the first terminal do not belong to the private network terminal under the same base station, so the access traffic sent by the first terminal may still be processed in the original manner, which is not limited in this embodiment.

It may be understood that, in this embodiment, taking terminal information as an IP address for example, a first session end may be generated according to a first IP address corresponding to a first terminal, and a second session end may be generated according to a second IP address corresponding to a second terminal, so as to construct a data transmission channel between the first session end and the second session end, thereby establishing a bidirectional data session between the first terminal and the second terminal.
It should be noted that, one terminal may simultaneously maintain a bidirectional data session with a plurality of other terminals, that is, the plurality of bidirectional data sessions may not interfere with each other, which is not limited in this embodiment.
And the service forwarding module 30 is configured to perform data interconnection between the first terminal and the second terminal through the bidirectional data session.
It should be understood that after the bidirectional data session between the first terminal and the second terminal is established, the data interconnection between the first terminal and the second terminal can be performed through the bidirectional data session, and through the interaction between the terminal interconnection module and the master control transmission unit, the data forwarding and the traffic statistics between different private network terminals under the same base station can be realized locally at the terminal, so that the transmission link is shortened, the transmission efficiency is improved, and the uplink and downlink traffic load of the base station is also lightened.
Therefore, the scheme solves the problem that the terminal interview under the same base station bypasses through the core network, realizes the rapid termination of the data flow through the internal forwarding of the local BBU, and improves the data transmission efficiency of the private network terminal under the same base station.

In an embodiment, the service identification module is further configured to determine a set of IP addresses to be selected according to the current instance information; detecting whether the set of the IP addresses to be selected contains the second IP address or not; and judging whether the second terminal and the first terminal are in the same private network under the base station according to the detection result.
