Method and device for carrying out hot backup on services

Abstract

The invention discloses a method and a device for carrying out hot backup on services, by which the service hot backup under the condition of RRU (radio remote unit) annular connection is realized quickly and effectively, and the problem of service interruption caused by that the time delay for realizing the service hot backup is long in the prior art is solved. The method comprises the following steps that: after an RRU accesses to a BBU (building base band unit), the BBU establishes a channel, and calculates and allocates a first delay measurement value and a second delay measurement value, wherein the first delay measurement value refers to a value of time delay that the RRU accesses to the BBU from a first link, and the second delay measurement value refers to a value of time delay that the RRU accesses to the BBU from a second link; after carrying out parameter configuration and cell configuration on the RRU, the BBU carries out service interaction on the first link; when determining that the first link is at fault, the BBU enables an IQ (intelligent) configuration corresponding to the first link and enables an IQ configuration corresponding to the second link; and after the RRU switches a clock from the first link to the second link and configures the time delay value from the first delay measurement value to the second delay measurement value, the BBU continues to perform the service above with the RRU.

Description

technical field [0001] The invention relates to the communication field, in particular to a method and device for service hot backup. Background technique [0002] At present, according to the definition of "2GHz TD-SCDMA Digital Cellular Mobile Communication Network - Ir Interface Technical Requirements for Distributed Base Stations" (hereinafter referred to as "TD-S Ir Interface Technical Requirements"), in the RRU (Radio Remote Unit, remote radio module) In the ring connection process, only link cold backup can be realized, and link hot backup cannot be realized; figure 1 Shown is a flow chart of realizing link cold backup of RRU ring connection in the prior art, and the process includes the following steps: [0003] Step 101, the RRU is connected to a BBU (Building Base band Unit, baseband processing unit) in a broadcast access manner. [0004] Step 102, establishing a channel between the RRU and the BBU, and enabling heartbeat detection. [0005] Step 103, the BBU me...
