Abstract

The invention is related to method for upgrading software in wireless communication system in order to guarantee that RRU can be upgraded reliably, stably, and rapidly. The invention includes steps: (1) radio frequency unit (RFU) at remote end loads software of optical interface module (OIM) in current version, and reports the version of software to up level; (2) baseband pool unit determines whether software of OIM is needed to upgrade; if yes, then RFU at remote end down loads software of OIM in new version from the baseband pool unit, and saves it to built in memory and loads and runs it; if not, then ending step; (3) RFU at remote end detects whether communication link on the optical interface is normal; if yes, then upgrading operation is successful; if not, then RFU at remote end resets and loads software of OIM in old version. The invention reduces increment of network flux caused by that multiple RRUs obtain software of OIM from BBU at same time.

Description

technical field

[0001] The invention relates to a software upgrading method in a wireless communication system, in particular to a software upgrading method of a remote radio frequency unit in a wireless communication system. Background technique

[0002] The development trend of the wireless communication system architecture is to separate the radio frequency unit from the baseband control unit, and connect the two through long-distance transmission means (optical fiber or cable), so that the radio frequency unit can be placed in various places where needed. The advantage of this architecture is that the entire system is divided into two relatively independent parts for independent development, and multiple radio frequency units share a baseband control unit. This not only reduces the cost, but also improves the flexibility of networking and network coverage, and facilitates engineering installation.

[0003] Here, the two divided parts are respectively referred to as a b...
