Fig. 3 is a schematic structural diagram of a network system according to another embodiment of the present invention, and as shown in fig. 3, the system includes:
a first auxiliary link 205 arranged between the first main floor device and the second main floor device;
and a second auxiliary link 206 disposed between the first slave landing device and the second slave landing device.
Specifically, the first auxiliary link 205 is disposed between the first main floor device 2011 and the second main floor device 2021, and when the first link 203 fails, data interaction between the first main floor device 2011 and the second main floor device 2021 can be achieved through the first auxiliary link 205. The second auxiliary link 206 is disposed between the first slave console device 2012 and the second slave console device 2022, and when the second link 206 fails, data interaction between the first slave console device 2012 and the second slave console device 2022 can be realized through the second auxiliary link 206.

On the basis of the foregoing embodiments, the service time slots corresponding to the first master landing device and the second master landing device are the same as the service time slots corresponding to the first slave landing device and the second slave landing device.
Specifically, in order to enable normal interaction of data, service time slots corresponding to the first master landing device and the second master landing device are consistent, correspondingly, service time slots corresponding to the first slave landing device and the second slave landing device are also consistent, and a standard mode of the service time slots may be a 3-7-3 mode. It should be noted that the time slot alignment operation should be performed according to ITU standards for the first master landing device, the first slave landing device, the second master landing device, and the second slave landing device of different manufacturers. It should be noted that, the service time slots corresponding to the first master landing device, the first slave landing device, and the at least one first network element device in the first network subsystem are the same, and the service time slots corresponding to the at least one second network element device, the second master landing device, and the second slave landing device in the second network subsystem are the same.
The embodiment of the invention ensures the normal transmission of data by setting the service time slots corresponding to the first master landing device and the second master landing device to be the same as the service time slots corresponding to the first slave landing device and the second slave landing device.
On the basis of the above embodiment, the first network element device is configured to send data only to the first main ground device according to a second preset working mode, and receive data returned by the first main ground device; and the second main ground equipment is used for sending the data sent by the second network element equipment to the first main ground equipment only according to the second preset working mode and receiving the data returned by the first main ground equipment.
Specifically, in the second preset operating mode, the first network element device 2013 only sends data to the first master floor device 2011 and receives data returned by the first master floor device 2011, and the second master floor device 2021 only sends data to the first master floor device 2011 and receives data returned by the first master floor device 2011. The embodiment of the invention can ensure the full utilization of resources. As shown in fig. 2, when data exchange is performed using the first master floor device 2011, the first slave floor device 2012, the second master floor device 2021, and the second slave floor device 2022, only the multiplex section data between the second master floor device 2021 and the second slave floor device 2022 can be used, because the second master floor device 2021 needs to transmit data to the first master floor device 2011 and the second slave floor device 2022 at the same time when transmitting data. If the data interaction is not performed by the first slave floor device 2012 and the second slave floor device 2022, the second master floor device 2021 only needs to send the data to the first master floor device 2011, and resources of a link between the second master floor device 2021 and the second slave floor device 2022 do not need to be occupied. If the available resource between the second master floor device 2021 and the second slave floor device 2022 is 64XVC4 ═ 10G, the available resource is reduced by half because the first slave floor device 2012 and the second slave floor device 2022 are added and data interaction is performed by the first slave floor device 2012 and the second slave floor device 2022, and only 32XVC4 on the link between the second master floor device 2021 and the second slave floor device 2022 can be used. Therefore, according to the importance degree of the data, the data is classified in advance, such as gold level (very important, e.g., VIP base station service) and silver level (generally important, e.g., indoor base station service), for the silver level data, the first slave landing device 2012 and the second slave landing device 2022 are not used, fig. 4 is a schematic structural diagram of the silver level data interaction network system provided by the embodiment of the present invention, as shown in fig. 4, a1 is a first master landing device, a2 is a second master landing device, C1 and D1 are first network element devices, C2 and D2 are landing devices, and BSC is a second network element device. Take the data transfer from BSC to C1 as an example: the data of the BSC is firstly sent to the A2 through the C2, the A2 sends the data to the A1 through the first link after receiving the data sent by the C2, if the first link fails, the data can be transmitted through the first auxiliary link, and the A1 sends the data to the C1 after receiving the data, so that cross-network transmission of the data is achieved.
According to the embodiment of the invention, the silver-level data is transmitted only by using the first main landing equipment and the second main landing equipment, so that resources between the second main landing equipment and the second slave landing equipment are fully utilized.

That is, when the first master landing device works normally and the link between the first master landing device and the first network element device works normally, the first network element device receives data sent by the first master landing device, and otherwise, receives data sent by the first slave landing device.

(2) Second master floor device a2 failed: if the C1 sends data to the BSC, the C1 sends the data to A1 and B1 respectively through a pseudo-wire dual-homing working mode, the A2 cannot receive the data sent by the A1 due to the fact that the A2 fails, at the moment, the B1 sends the data to the B2 through a second link or a second auxiliary link, and the B2 sends the data to the BSC through the D2 and the C2, so that data transmission from the C1 to the BSC is achieved; if the BSC sends data to C1, the BSC sends the data to C2, C2 sends the data to B2 through D2 by multiplexing segment switching, B2 sends the data to B1 through a second link or a second auxiliary link, a1 does not receive the data because a2 fails, at this time, B1 sends the data to C1, thereby realizing data transmission from the BSC to C1.
