Embodiment Construction

[0023] The specific implementation manners of the present invention will be described in detail below with reference to the accompanying drawings.

[0024] The remote node version upgrading method of the present invention is applicable to a base station system in the field of mobile communication, and the base station system includes a foreground and a background, wherein the foreground includes a BBU and an RRU. The version upgrade request is initiated by the BBU. According to the types of all RRU radio frequency resources currently configured and the version currently running on the RRU, the software version to be upgraded is selected from the specified upgrade version package, and the multiple RRUs connected to the BBU are sequentially processed. version upgrade.

[0025] Aiming at all RRU types with multiple specifications at present, the present invention makes all RRU software versions with different specifications into the same software version package, and publishes it...

Abstract

The invention provides a method for edition upgrading comprising: step S102, baseband unit judges if the radio frequency radio unit needs upgrading edition according to one or multiple operation edition information reported by radio frequency radio unit; then notifies radio frequency radio unit to upgrading edition if needed; step S104, radio frequency radio unit receives notice for edition upgrading, then responds and transmits data packet downloading request to baseband unit; step S106, baseband unit receives data packet downloading request, then transmits the edition information requested by radio frequency radio unit to radio frequency radio unit for edition upgrading. The method can be used in wireless base station system by adopting combined downloading for software edition and hardware edition for implementing RRU edition upgrading, thereby promoting upgrading efficiency and correctness.

Description

technical field [0001] The invention relates to the communication field, in particular to a method for upgrading a version of a remote node. Background technique [0002] In the time division synchronous code division multiple access cellular mobile communication system, the NodeB Application Part (NBAP) is divided into a base band unit (Base Band Unit, BBU) and a radio frequency remote unit (Radio Remote Unit, RRU) through radio remote control. ) two parts, the two are connected through a long-distance transmission line, a single BBU can be connected to one or more RRUs (RRU chains), and the RRUs can include a variety of different specifications. In this case, the version upgrade of the NodeB has caused considerable difficulties, especially the version upgrade of the RRU. [0003] In the previous version upgrade of RRU, a single version software download method was used to upgrade the software of different specifications (radio frequency resource type), different hardware ...
