Selection of channel for radio resource control signaling in HSDPA
First Claim
Patent Images
1. A signaling method implemented by a radio network controller, said method comprising:
- determining a mobility rate of a mobile station;
selecting, when the mobility rate is low, a shared high speed downlink channel for sending both user data and in-band signaling of radio resource control messages on the same channel;
selecting, when the mobility rate is high, a dedicated downlink channel for sending the radio resource control messages while using the shared high speed downlink channel for sending the user data; and
configuring the signaling connection with the mobile station to use the selected downlink channel.

Abstract
A Radio Network Controller (RNC) is configured to send Radio Resource Control (RRC) messages to a mobile station using a selected downlink channel. Depending on the mobility rate of the mobile station, the RNC is configured to configure a signaling connection to use either a first downlink channel or a second downlink channel for transmitting the RRC messages. According to one embodiment, the RNC selects a dedicated channel when the mobile station has a high mobility rate, and selects a shared channel when the mobile station has a low mobility rate.
