Abstract
Abstract In a packet radio system (e.g. a GPRS), a network (BSS) has two different alternatives for allocating a radio resource to a mobile station (MS). In a first allocation alternative the radio resource is allocated using an uplink counter block identifier (USF) transmitted with downlink blocks. In a second allocation alternative the radio resource is allocated in a separate signalling message. A corresponding downlink block then also has an uplink counter block identifier (USF) which can acquire only a limited number of possible values. If all identifiers (USF) are allocated to different mobile stations, allocation alternative 2 cannot be used. In the invention the network leaves at least one identifier (USF) unallocated to any mobile station. In addition, the network either (1) uses the identifier in downlink blocks corresponding to blocks reserved using the second allocation alternative; or (2) at least one uplink counter block identifier (USF) is separately determined, said identifier denoting a reserved uplink block which the mobile station cannot use for transmission without a separate authorisation.

Claims Analysis
Total Claims: 8
Claim 1
Independent Claim
156 words
A method for allocating a radio resource to at least one of a plurality of mobile stations for an uplink transmission in a packet radio network, the network having at least two alternative techniques for allocating the resource, the at least two techniques including: a first technique adapted to allocate the radio resource in a first signaling message, the first signaling message assigning a radio block for the at least one mobile station to use for the uplink transmission; a second technique adapted to allocate the radio resource in a second signaling message, the second signaling message assigning the radio block for the at least one mobile station to use for the uplink transmission; the method comprising: leaving at least one uplink status flag unallocated to any mobile station when the second technique is used; and using the unallocated uplink status flag in a downlink block corresponding to the radio block assigned using the second technique.
Claim 2
Independent Claim
156 words
A method for allocating a radio resource to at least one of a plurality of mobile stations for an uplink transmission in a packet radio network, the network having at least two alternative techniques for allocating the resource, the at least two techniques including: a first technique adapted to allocate the radio resource in a first signaling message, the first signaling message assigning a radio block for the at least one mobile station to use for the uplink transmission; a second technique adapted to allocate the radio resource in a second signaling message, the second signaling message assigning the radio block for the at least one mobile station to use for the uplink transmission; the method comprising: leaving at least one uplink status flag unallocated to any mobile station when the second technique is used; and using the unallocated uplink status flag in a downlink block corresponding to the radio block assigned using the second technique.
Claim 3
Independent Claim
163 words
A method for allocating a radio resource to at least one of a plurality of mobile stations for an uplink transmission in a packet radio network, the network having at least two alternative techniques for allocating the resource, the at least two different techniques including: a first technique adapted to allocate the radio resource in a first signaling message, the first signaling message assigning a radio block for the at least one mobile station to use for the uplink transmission; a second technique adapted to allocate the radio resource in a second signaling message, the second signaling message assigning the radio block for the at least one mobile station to use for the uplink transmission; the method comprising: leaving at least one uplink status flag unallocated to any mobile station when the second technique is used; and using the unallocated uplink status flag to denote a reserved uplink block which cannot be used by any mobile station for transmission without a separate authorization.
Claim 4
Independent Claim
163 words
A method for allocating a radio resource to at least one of a plurality of mobile stations for an uplink transmission in a packet radio network, the network having at least two alternative techniques for allocating the resource, the at least two different techniques including: a first technique adapted to allocate the radio resource in a first signaling message, the first signaling message assigning a radio block for the at least one mobile station to use for the uplink transmission; a second technique adapted to allocate the radio resource in a second signaling message, the second signaling message assigning the radio block for the at least one mobile station to use for the uplink transmission; the method comprising: leaving at least one uplink status flag unallocated to any mobile station when the second technique is used; and using the unallocated uplink status flag to denote a reserved uplink block which cannot be used by any mobile station for transmission without a separate authorization.
