Abstract
The present invention relates to improvements for a fast setup of physical communication channels in a CDMA-based communication system. A Node B of a telecommunication network is permitted to manage and assign a certain share of the downlink transmission resources of a radio network controller without inquiry of said radio network controller. On reception of a resource request message from a user equipment, the node B derives and specifies a certain amount of said resources that can be allocated to the user equipment. In a preferred embodiment of the present invention said resources are only assigned temporarily until the ordinary RL setup procedure, which involves the RNC, has been successfully finished.
Claims7
A method in a Node B of a telecommunication network for fast setup of a physical communication channel, comprising the steps of:
- managing an assigned share of downlink transmission resources of a radio network controller without inquiry of said radio network controller;
- maintaining a user equipment communication context, wherein said communication context includes an identifier of said user equipment;
- deriving and specifying by help of said user equipment communication context, on reception of a resource request message from a user equipment on a random access channel including at least said identifier of said user equipment, a subset of said assigned share of said downlink transmission resources that can be assigned to said user equipment;
- and
- assigning over a control channel the specified subset of resources to the user equipment by help of a resource assignment message including the parameters that are necessary for establishing the dedicated channel.
