Method and Arrangement for Activity Detection in a Telecommunication System
First Claim
1. A method in a communication system comprising a plurality of interconnected network nodes, including one or more radio base stations and one or more user equipments introducing a set of rules commonly known to the radio base stations and user equipments in order to independently initiate or perform in one of said units a state transition to or from a reduced transmission activity mode when a predefined criterion has been fulfilled.

Abstract
The present invention relates to a method and arrangement for efficient use of network resources, in particular for continuous connectivity services. The present invention introduces a set of established rules for uplink and/or downlink activity detection such that a Node B and/or a UE is enabled to detect active and inactive transmission periods on links for reception of packet data transmission and can independently arrange for inactivity/activity state transitions without any need of further signalling. Such a set of rules can be communicated to the Node B and the user equipment, e.g., from the radio network controller (RNC), or can consist of a predefined set of fixed rules that is readily implemented in said units.

18. A radio base station in a communication system comprising a plurality of interconnected network nodes, said radio base station communicating with one or more user equipments comprising:
-
means for storing a set of rules to independently initiate or perform a state transition to or from a reduced transmission activity mode when a predefined criterion has been fulfilled; means for transmission activity detection on the uplink and the downlink; means for maintaining a plurality of timers, one for each user equipment and transmission direction;
including a means for storing of timer expiration values, a means for indicating that a timer has expired, and a means for restarting the timer of a user equipment if transmission activity has been detected to or from said user equipment;means for performing said state transition in accordance with one of said stored rules for a user equipment with an expired timer. - View Dependent Claims (19, 20)
