Access node selection in a network
First Claim
1. A method of access selection by a wireless communication network node for a terminal communicating with the network having one or more access nodes configured for providing access to the terminal according to one or more access technologies, the method comprising:
- determining whether at least one network parameter comprising cell load associated with the network and that is provided by a network node and that cannot be measured or determined by the terminal is required as input for access selection for the terminal;
obtaining a network parameter comprising the cell load that cannot be measured or determined by the terminal if it is determined that the at least one network parameter is required as input for access selection for the terminal;
selecting an access node for the terminal based at least in part on the network parameter each time the determination is made; and
initiating or continuing terminal-based access selection if it is determined that no network parameter is required as input for the access selection.

Abstract
The invention is directed towards determining an access node (14, 16) for a terminal (18) in a network (10) having one or more access nodes capable of providing access to the terminal based on one or more access technologies. Access node is selected through determining whether at least one network parameter provided by a network node (12, 14, 16) is required as input for the access node selection for the terminal. If it is determined that the at least one network parameter is required as input, the network parameter is obtained and an access node possibly together with access type for the terminal is selected at least based on said network parameter.
