Methods and devices for optimal selection of core network nodes in a cellular communication network

摘要

Devices and methods for selecting network nodes in a cellular communication network. By dropping fixed connections between network nodes of different hierarchy levels, for instance, a network node of an access network has to make a selection among different core network nodes. The selected core network node requires service information on the access network node and the area serviced by the access network node. Devices and methods are disclosed for selecting network nodes and for providing service information. The devices can be implemented in the network centrally or in a distributed manner.

1. Selection device (AVK1, AVK2) for selecting network nodes in a cellular communication network wherein a plurality of access network nodes can cooperate with a plurality of core network nodes in an n:m relation, wherein at least one of the access network nodes is capable of cooperating with more than one core network node, the selection device comprising an input/output unit (EAE1, EAE2) for receiving network node requests and for releasing a network node identification of the network node allocated to a network node request characterised by
a node capacity memory (KKD1, KKD2) for storing parameters, and a processing unit (AWE1, AWE2) for analyzing network node requests and for selecting a network node by means of the analysis result and the parameters stored in the node capacity memory.
