Method and device for relocating service between different types of base band boards

Abstract

The invention discloses a method and a device for relocating service between different types of base band boards. Service between the different types of the base band boards can be automatically relocated in a base station. The method comprises the following steps of: when the first base band board receives radio link reconfiguration request information which is transmitted by a radio network controller (RNC), if the request information comprises a new service which is unsupported by the first base band board, and a second base band board which supports the service exists, acquiring real time information of the radio link, and sending the acquired real time information and all the information of the radio link on the first base band board to the second base band board; and after a new radio link is established on the second base band board, activating the new radio link, and deleting the original radio link on the first base band board, and switching a carrier from the first base band board to the second base band board.

Description

technical field [0001] The present invention relates to the field of communications, and more specifically, to a method and device for relocating services between different types of baseband boards. Background technique [0002] With the advancement of communication technology, the processing capability of Node B (Node B) is getting stronger and stronger, which is mainly reflected in the increasing processing capability of the baseband board, which will produce different types of baseband boards, and the processing capacity of each baseband board The capabilities are different; moreover, with the upgrade of the protocol, the service capabilities supported by WCDMA have been changing, from the initial R99, DPA (Downlink Packet Access, downlink packet access), UPA (Uplink Packet Access, uplink packet access) Access) low-level business later added MIMO (Multiple Input Multiple Output, multiple transmission and multiple reception), CPC (Continuous Packet Connectivity, continuous...

[0002] With the advancement of communication technology, the processing capability of Node B (Node B) is getting stronger and stronger, which is mainly reflected in the increasing processing capability of the baseband board, which will produce different types of baseband boards, and the processing capacity of each baseband board The capabilities are different; moreover, with the upgrade of the protocol, the service capabilities supported by WCDMA have been changing, from the initial R99, DPA (Downlink Packet Access, downlink packet access), UPA (Uplink Packet Access, uplink packet access) Access) low-level business later added MIMO (Multiple Input Multiple Output, multiple transmission and multiple reception), CPC (Continuous Packet Connectivity, continuous connection), DC (Dual Cell, dual carrier), uplink 16QAM (Quadrature Amplitude Modulation, quadrature amplitude modulation ) and other new advanced services, but these functional requirements were not available when the baseband board was originally designed. Therefore, the old baseband board does not support some very important functions at present

The outfield commercial office still has these old baseband boards in use, but later used new baseband boards for expansion, so there is a phenomenon of mixed insertion of different types of baseband boards

[0003] In order to enable the base station to be upgraded smoothly and reduce the hardware cost of the operator, it is necessary to insert a new baseband board into the old base station to support new services. In this way, a problem arises: when there are multiple types of When using existing baseband boards, there are always some low-level services running on some old baseband boards. When these services are reconfigured into high-level services, some old baseband boards cannot handle new high-level services. At this time, NodeB must be able to Automatically relocate these services from the old baseband board to the new baseband board to achieve seamless switching without call drop
