Signaling method for CDMA quality based power control

A mobile telecommunications system comprising:

• a base station having a radio channel connection to a mobile station using code division multiple access, the base station receiving a signal transmitted from the mobile station and determining a signal to interference/noise ratio therefor, making a comparison of the signal to interference/noise ratio for the mobile station with a target signal to interference/noise ratio, and transmitting a power level command to the mobile station in accordance with the comparison;
• a mobile switching center which is connected over a link to the base station, the mobile switching center generating information for updating the target signal to interference/noise ratio (TSINR) and transmitting the information for updating the target signal to interference/noise ratio to the base station over the link using in-band signaling, the link cog traffic connection frame packets of information having payloads which include user data, and wherein the information for updating the target six to interference/noise ratio is stored in the traffic connection frame packets.
