Description

Method for opening base station, operation maintenance center and storage medium

Technical Field

The present disclosure relates to the field of wireless communications technologies, and in particular, to a method for opening a base station, an OMC (Operation & Maintenance Center), and a storage medium.

Background

With the rapid development of wireless mobile communication technology, networks have already gone into flattening, and the traditional manual wireless base station opening mode not only consumes a large amount of manpower, but also has slow station opening speed, low efficiency and high cost, is a consensus in the industry, and has not been able to meet the requirements of rapid opening and intelligent operation and maintenance of modern networks. Under the background, many manufacturers propose automatic station opening methods such as PnP (Plug and play) or DHCP (Dynamic Host Configuration Protocol), which actually improve the efficiency to a certain extent and reduce the skill requirements on the openers. However, most of such automatic opening methods require that the DHCP server and the base station to be opened are in the same network segment (as shown in fig. 1), and the DHCP server can directly allocate IP configuration to the base station to be opened, and implement and operate the link establishment of the maintenance center OMC, thereby implementing self-opening and self-configuration. Or as shown in fig. 2, the transmission network from the base station to the OMC supports a DHCP relay scenario, and the base station to be opened can request an IP configuration from a DHCP server through a standard DHCP or DHCP relay flow through a DHCP relay on a three-layer gateway, thereby establishing a transmission link between the base station to be opened and the OMC, and implementing self-opening and self-configuration. However, in reality, most of operator transmission networks do not support the DHCP relay function, thereby greatly limiting the application scenarios of the base station self-configuration and self-activation. Due to the flattening of the 4G network, operators usually do not independently deploy the DHCP server in each network segment for cost saving and maintenance cost saving, and many operators cannot meet the requirements for the transmission network, and the transmission modification period is long, and the cost is high, so that the scheme cannot be widely popularized outside the field.

Therefore, in an application scenario that a DHCP server is not deployed in a network segment where a base station to be opened is located, or a three-layer gateway where a network segment to which the base station to be opened belongs is located does not support DHCP relay, the base station cannot automatically open and automatically configure functions.

In this embodiment, the OMC and eNodeB a will complete the interaction of the IP parameter information of all base stations in the subnet. The opened eNodeB a may be a base station that has established a link with the OMC and can normally interact in the subnet, and is usually one of the first/first normally opened base stations in the subnet. The eNodeB B to be opened refers to all other base stations to be opened in the same subnet as the eNodeB A, and is a target base station for self-opening and self-configuration. The method for opening an eNodeB provided by the embodiment of the disclosure comprises the following steps:

1. and finishing the configuration of the base station to be opened on the OMC.

Specifically, the OMC completes configuration of the base station planning data of the subnet. For eNodeB B, all enodebs have basic versions and basic configuration parameters when leaving the factory, so that it is ensured that the base station can be started normally after being powered on. And meanwhile, the base station is self-started, and the self-configuration DHCP Client switch is in an open state. The switch is used for starting the DHCP Client function of the base station and ensuring that the base station automatically broadcasts the DHCP configuration request when the OMC link IP configuration is lacked after being electrified. An Electronic Serial Number (ESN) of an eNodeB B B, wherein the ESN is burned into a base station ROM (read only memory) during base station production and cannot be modified, but the eNodeB can acquire the ESN and report the ESN to an OMC (operation management center) to determine the identity of the base station as a unique identifier, and management channel parameters (including a management channel IP (Internet protocol) address, a subnet mask, a gateway and a VLAN (virtual local area network) identifier), target configuration data (including physical configuration of the eNodeB, S1/X2 transmission configuration and wireless parameter configuration) and target version information (target version to be updated of the eNodeB.

Specifically, after receiving the request from the eNodeB a, the OMC transmits the base station planning data to the eNodeB a.

6. The eNodeB a opens the DHCP service.

Specifically, after receiving the base station planning data, the eNodeB a starts a DHCP server function in the subnet, and provides an IP address assignment service to all eNodeB bs. And starts to listen to the DHCPDISCOVER message of eNodeB B within the subnet.

7. VLAN detection, DHCP configuration request.

Specifically, after the base station eNodeB B is powered on, the self-start and self-configuration switch state is detected, and if the switch is in the on state, the self-start and self-configuration process is started.

8. eNodeB a assigns eNodeB B an IP configuration.

Specifically, after receiving the broadcast message of eNodeB B, eNodeB a may further obtain ESN information in the message, compare the ESN information with the planning data of the base station, determine the IP configuration of the management channel of eNodeB B, and reply a DHCP OFFER to the second base station. And the second base station receives the DHCP OFFER message, wherein the message comprises the management channel IP configuration to be allocated to the second base station. Based on the VLAN condition detected before, the second base station sends a DHCP request broadcast message and formally requests an eNodeB A/DHCP server to allocate the management channel IP configuration provided in the DHCP OFFER message.
