Software updating method of controlled network element, controlled network element and operation maintaining center

Abstract

The invention discloses a software updating method of a controlled network element and a controlled network element, and an operation maintenance center, wherein the method comprises: the step A1, the operation maintenance center OMC determines a controlled network element updating software package according to reported information of the controlled network element, the updating software package is higher than the prior software release of the controlled network element; the step A2, the OMC creates a multicast group corresponding to the updating software package, and notifies the controlled network element; the step A3, the controlled network element joins the multicast group corresponding to the updating software package, and performs the communication based on the multicast protocol, and receives the updating software package from the OMC. The invention lowers the load of the operation maintenance center, improves the using efficiency of the network bandwidth, and improves the success ratio of updating the software package and the reliability of the system.

Description

technical field [0001] The invention relates to system software update in the field of mobile communication, in particular to a method for updating software of a controlled network element, a controlled network element, and an operation and maintenance center in the field of mobile communication. Background technique [0002] In existing mobile communication systems, such as figure 1 As shown, the controlled network element (such as base station, relay station, etc.) interacts with the network element OMC (Operation and Maintenance Center, Operation and Maintenance Center) that implements the management function through RNC (Radio Network Controller, radio network controller) to realize the software Version updates. [0003] Such as figure 2 As shown, taking the controlled network element as NB (Node B, Node B) as an example, its software version management method includes: [0004] Step 21, NB, as a client, sends a version file download request message to the OMC provid...

AI Technical Summary

Problems solved by technology

[0008] From the above description, it can be seen that the existing software update methods for controlled network elements are simple and intuitive. When the number of network elements is large, the load pressure on the OMC is high. At the same time, the use of point-to-point unicast mode results in low bandwidth utilization
