Method of managing processing resources in a mobile radio system
View Patent ↗A method of managing processing resources in a mobile radio system, in which a first entity manages radio resources and corresponding processing resources, the latter being provided in a second entity separate from the first entity. The second entity signals to the first entity its global processing capacity, or capacity credit, and the consumption law, or quantity of the global processing capacity, or cost, for different spreading factor values. The first entity updates the capacity credit on the basis of the consumption law. In the case of multicode transmission using N spreading codes, the updating is effected on the basis of the cost for at least one of the N spreading codes.
1. A method of managing processing resources in a mobile radio system, wherein:
a base station signals to a radio network controller a capacity credit and a capacity consumption law giving costs per spreading code,
the radio network controller updates the capacity credit on the basis of the capacity consumption law, and
in the case of multicode transmission using N spreading codes, said updating is effected on the basis of the cost for at least one of the N spreading codes.
2. A method according to claim 1 , wherein the cost for the N codes corresponds to the sum of the costs for each of the N codes.
3. A method according to claim 1 , wherein the cost for the N codes is determined from the cost for one code.
4. A method according to claim 3 , wherein the cost for the N codes corresponds to the cost for the minimum spreading factor code.
5. A mobile radio system comprising
a base station comprising means for signaling to a radio network controller a capacity credit and a capacity consumption law giving costs per spreading code, and
a radio network controller comprising means for, in the case of multicode transmission N spreading codes, updating the capacity credit on the basis of the cost for at least one of the N spreading codes.
6. A radio network controller comprising:
means for receiving from a base station a capacity credit and a capacity consumption law giving costs per spreading code, and
means for, in the case of multicode transmission using N spreading codes, updating the capacity credit on the basis of the cost for at least one of the N spreading codes.
7. A load control and/or call admission control method in a mobile radio system, wherein:
a base station signals to a radio network control a capacity credit, and a capacity consumption law,
the radio network controller updates the capacity credit on the basis of the consumption law, and
if the capacity credit in the uplink and/or downlink direction falls below a given first threshold, any new call is rejected until the capacity credit is again above a given second threshold greater than or equal to the first threshold.
8. A mobile radio system comprising
a base station comprising means for signaling to a radio network controller a capacity credit and a capacity consumption law,
a radio network controller comprising means for updating the capacity credit on the basis of the capacity consumption law, and
a radio network control comprising means for rejecting any new call if the uplink and/or downlink capacity credit falls below a given first threshold until the capacity credit is again above a given second threshold greater than or equal to the first threshold.
9. A radio network controller comprising:
means for receiving from a base station a capacity credit and a capacity consumption law,
means for updating the capacity credit on the basis of the capacity consumption law, and
means for rejecting any new call if the uplink and/or downlink capacity credit falls below a given first threshold until the capacity credit is again above a given second threshold greater than or equal to the first threshold.
10. A load control and/or call admission control method in a mobile radio system, wherein:
a base station signals to a radio network controller a capacity credit, and a capacity consumption law,
the radio network controller updates the capacity credit on the basis of the capacity consumption law, and
an overload control procedure is initiated if the capacity credit falls below a given threshold.
11. A mobile radio communication system, comprising:
a base station comprising means for signaling to a radio network controller a capacity credit and a capacity consumption law,
a radio network controller comprising means for updating the capacity credit on the basis of the capacity consumption law, and
means for initiating an overload control procedure if the capacity credit falls below a given threshold.
12. A radio network controller comprising:
means for receiving from a base station a capacity credit and a capacity consumption law,
means for updating the capacity credit on the basis of the capacity consumption law, and
means for initiating an overload control procedure if the capacity credit falls below a given threshold.
13. A method of managing processing resources in a mobile radio system, wherein:
a base station signals to a radio network controller a capacity credit and a dedicated channels capacity consumption law giving costs per channelization code, and
when multiple channelization codes are used by either radio links or a physical downlink shared channel, the radio network controller credits to or debits from the capacity credit a cost taken as N times the cost of a code, where N is the number of channelization codes.
