Abstract
Abstract The invention relates to a method in connection with handoff in a mobile radio communication system comprising at least one mobile station and a set of base stations (BS1, BS5) surrounding said mobile station, each of said base stations including at least one traffic channel. The invention is characterized in that measured information that is significant for handoff-decisions and that before handoff of the mobile station from a first traffic channel to a second traffic channel has been measured, stored and associated with the first traffic channel, in connection with handoff is associated with the second traffic channel.

Claims Analysis
Total Claims: 5
Claim 1
Independent Claim
96 words
A method in connection with handoff in a mobile radio communication system comprising at least one mobile station (MS) and a set of base stations (BS1-BS7) surrounding said mobile station, each of said base stations comprising at least one traffic channel, characterized in that measured information (SS, BER, TD, C/I) that is relevant for handoff decisions and that before handoff of said mobile station from a first traffic channel to a second traffic channel has been measured, stored and associated with said first traffic channel, in connection with handoff is associated with said second traffic channel.
Claim 2
Dependent Claim
54 words
The method of claim 1, characterized in that said first traffic channel belongs to a first base station (BS1) and said second traffic channel belongs to a second base station (BS5) in said set, and in that said measured information in connection with handoff is transferred from said first to said second base station.
Claim 3
Dependent Claim
62 words
The method of claim 2, characterized in that said measured information includes the signal strength (SS) and bit error rate (BER) of said first traffic channel for signals transmitted from said first base station (BS1) and the signal strength (SS) on the control channel of said mobile radio communication system for signals transmitted from the remaining base stations (BS2-BS7) in said set.
Claim 4
Dependent Claim
32 words
The method of claim 2 or 3, characterized in that said measured information includes the time dispersion (TD) on said first traffic channel for signals transmitted from said first base station (BS1).
Claim 5
Independent Claim
33 words
The method of any of the preceding claims, characterized in that said measured information includes the channel quality (C/I) on said first traffic channel for signals transmitted from said first base station (BS1).
