In the fourth embodiment of the present invention, the service processing unit can implement an access layer processing function of multiple access layer network devices on the network side of the existing LTE system and a non-access stratum processing function of the non-access stratum network device. Therefore, an LTE network device can replace multiple access layer network devices and non-access stratum network devices on the network side of the existing LTE system, thereby reducing the number of devices in the LTE system network, simplifying the network side architecture of the LTE system, and saving The manufacturing cost of the LTE system. In the LTE network device, an access layer processing sub-unit and a non-access stratum processing sub-unit are integrated in the service processing unit, and the LTE network device can simultaneously implement an access layer processing function and a non-access stratum processing function, and therefore, The LTE network device can be used as an integrated base station integrating the eNB and the LTE core network, and the LTE network device is used to replace the eNB in the existing LTE network architecture. And the LTE core network interacts with the UE device on the terminal side.

Further, on the basis of the foregoing, the hardware platform of the LTE network device includes an underlying hardware platform, a software platform disposed on the hardware platform, and a service processing unit disposed on the software platform, where the hardware platform provides hardware support for the service processing unit. The service processing unit replaces the eNB and the LTE core network of the existing LTE system by software, and implements an access layer processing function and a non-access layer processing function. Since the hardware platform of the LTE network device is composed of only a plurality of boards, the LTE network device has low manufacturing cost and small space. The LTE network device is used to replace the existing eNB and multiple devices in the LTE core network, which saves the network architecture cost of the LTE system. And the eNB and the LTE core network are integrated into one LTE network device in the fourth embodiment of the present invention, and the original eNB and the LTE core network interact with each other through a hardware communication interface, in the LTE mode. In the network device, the communication mechanism is used to implement communication between the access layer processing sub-unit and the non-access stratum processing sub-units through the message mechanism, thereby avoiding frequent interaction with the signaling through the communication interface. The resulting communication delay can reduce the service signaling delay of the LTE system.

It can be seen from the first embodiment of the present invention to the fourth embodiment of the present invention that, in the LTE network device proposed by the present invention, the access layer processing sub-unit and the non-access stratum in the service processing unit are based on the hardware platform and the software platform. The processing sub-units can be flexibly deployed, that is, the above two sub-units can be integrated into the LTE network device, or only one of the sub-units can be integrated into the LTE network device, thereby flexibly making an LTE network with different functions. device. If only the access layer processing sub-unit is deployed in the LTE network device, and the non-access stratum processing sub-unit is not deployed, the LTE network device is an LTE base station device, which can replace the eNB in the existing LTE system, through the SI interface. Interact with the LTE core network. If the access layer processing sub-unit and the non-access stratum processing sub-unit are simultaneously deployed in the LTE network device, the LTE network device is an LTE single-station device, and can simultaneously support the access layer function and the non-connection in the LTE system. The LTE network device can be operated in a single station to replace the eNB in the existing LTE system with the LTE core network, and the LTE network device interacts with the external device through the IP mode. If only the non-access stratum processing sub-unit is deployed in the LTE network device, and the access layer processing sub-unit is not deployed, the LTE network device is an LTE non-access stratum device, which can replace the LTE core in the existing LTE system. The LTE network device interacts with the base station through the S1 interface, and interacts with other network element devices through IP. The LTE network device can serve as a small-scale core. Used by network devices.

Moreover, the LTE network device proposed by the present invention supports an access layer processing function and a non-access stratum processing function of a data service, and the LTE network device can support a PS data service. The processing on the network side is transparent to the UE, and it is not necessary to modify the existing LTE Uu interface, and it is not necessary to modify the existing UE. The LTE network device can support PS data services, so there is no need to separately deploy the MME in the system. The LTE network device can also support cluster services, so there is no need to separately deploy the cluster processing unit in the system. In addition, the scheduling function may be integrated in the LTE network device provided by the present invention. Specifically, the interaction interface module, the conversion interface module, and the scheduling control module may be integrated in the LTE network device, or the interaction interface is not integrated in the LTE network device. The module and the conversion interface module are only integrated with the scheduling control module, and the dispatching station is connected outside the LTE network device, and the external dispatching station includes an interactive interface module and a conversion interface module, thereby providing scheduling of the broadband cluster service. With the LTE network device proposed by the present invention, the number of separated network elements in the LTE system is reduced. After the existing multiple network elements are integrated into one LTE network device, the signaling exchange between the existing network elements is simplified in the LTE network device to adopt message channel switching inside the device, thereby reducing signaling.
