Method and apparatus for realizing main standby inverting and load sharing

Abstract

The invention discloses a method for realizing active / standby changeover and load sharing, which comprises the following steps: a first veneer is designed as an active veneer, a second veneer is designed as a standby veneer, same service logic IP addresses are configured on the first veneer and the second veneer, and an interworking function IWF is invocated; when data link is in a normal state, the load sharing method is used for processing forward data by the first veneer and the second veneer; or when the data link fails, the second veneer is designed as the active veneer to process downlink-uplink data between an opposite terminal and the second veneer. Through the method provided by the embodiment, the same service logic IP addresses are arranged on the active and the standby veneers, and the IWF is invocated, so as to realize that the load sharing of the active and the standby veneers is used for processing the forward data; the logic IP address at a net opening in a back plate is only required to be switched, so as to realize the changeover of the active and the standby veneers, thereby ensuring that the forward data can still be normally processed by the equipment when the data link fails, and improving the reliability of the equipment.

Description

technical field [0001] The invention relates to the field of communication technology, in particular to a method and a device for realizing master-standby switching and load sharing. Background technique [0002] In a traditional GSM (Global System for Mobile Communications, digital cellular mobile communication system) core network, voice and data traffic are almost all transmitted through a TDM (Time Division Multiplexing, Time Division Multiplexing) circuit switching network. TDM refers to a technology that transmits multiple digitized data, voice and video signals, etc. on the same communication medium at the same time through cross-bit pulses in different channels or time slots. [0003] BSC (Base station controller, base station controller) is a gateway device of the wireless core network. When the data link fails, how to ensure the normal forwarding of data is a problem that users are very concerned about. In the TDM mode, the BSC adopts a 1+1 active / standby mode, th...

Problems solved by technology

[0006] The inventor found through research that the above-mentioned background technology has at least the following problems: on the one hand, when the data link is normal, the standby single board is in an idle state, resulting in waste of resources; on the other hand, when the data link fails, all uplink and downlink The data must be routed and converted between the boards, resulting in a large increase in the traffic in the entire board, which may be 3 times the normal time, or more

[0008] The inventor found through research that at least the following problems exist in the above-mentioned background technology 2: on the one hand, when the data link is normal, the standby single board is idle, resulting in waste of resources; on the other hand, the backplane data switching is a kind of mirror backup , all steady-state data of the main board needs to be backed up in real time, and the switching between the main board and the backup board needs to be smoothly processed, and the processing process is relatively complicated

[0012] The inventor found through research that there are at least the following problems in the above-mentioned background technology 3: On the one hand, when the data link of the main single board fails, all uplink and downlink data between the local device and the peer device must pass through the inter-board Route conversion doubles the data flow between boards, increasing processing overhead and delay; on the other hand, since the service logic IP address and IWF are only valid on the active board, when the active and standby single routes are switched, the business logic The IP address, IWF switch, internal IP, and MAC all need to be switched to the standby board and smoothed. The processing process is relatively complicated.
