Abstract
Abstract A process for dynamic channel allocation in mobile radio networks, wherein priorities which are increased or decreased in dependence on interference occurring in the channel concerned are established for the individual channels. When the propagation conditions are satisfactory, channels with low priority can be allocated. The mean of values dependent on the extent of interference can be formed in order to increase and decrease the priority. In addition, various priority lists can be established for various interference or load situations, or both.

Claims Analysis
Total Claims: 8
Claim 1
Independent Claim
126 words
A process for dynamic channel allocation in mobile radio networks, said process comprising the steps of: establishing priorities for a plurality of individual channels; increasing or decreasing the priorities as a function of interference occurring in each respective channel, where channels with a low priority are preferably occupied relative to channels with a high priority when there are good propagation conditions; and taking into account a threshold value (CIRt), in particular the carrier/interference ratio (CIR), which is used in testing whether or not a channel is to be occupied; wherein the threshold value (CIRt) is a function of the priority (P) of the respective channel, where said function starts from a constant value and follows a course that decreases monotonically as the priority (P) becomes lower.
Claim 2
Dependent Claim
126 words
A process for dynamic channel allocation in mobile radio networks, said process comprising the steps of: establishing priorities for a plurality of individual channels; increasing or decreasing the priorities as a function of interference occurring in each respective channel, where channels with a low priority are preferably occupied relative to channels with a high priority when there are good propagation conditions; and taking into account a threshold value (CIRt), in particular the carrier/interference ratio (CIR), which is used in testing whether or not a channel is to be occupied; wherein the threshold value (CIRt) is a function of the priority (P) of the respective channel, where said function starts from a constant value and follows a course that decreases monotonically as the priority (P) becomes lower.
Claim 3
Dependent Claim
12 words
The process according to claim 1, wherein the declining course is logarithmic.
Claim 4
Dependent Claim
146 words
A process for dynamic channel allocation in mobile radio networks, said process comprising the steps of: establishing priorities for a plurality of individual channels; increasing or decreasing the priorities as a function of interference occurring in each respective channel, where channels with a lower priority are preferably occupied relative to channels with a high priority when there are good propagation conditions; and taking into account a threshold value (CIRt), in particular the carrier/interference ratio (CIR), which is used in testing whether or not a channel is to be occupied; wherein the threshold value (CIRt) is a function of the priority (P) of the respective channel, where said function starts from a constant value and follows a course that decreases monotonically as the priority (P) becomes lower; and wherein a quantity that depends on an extent of the interference is averaged to increase or decrease the priority.
Claim 5
Dependent Claim
146 words
A process for dynamic channel allocation in mobile radio networks, said process comprising the steps of: establishing priorities for a plurality of individual channels; increasing or decreasing the priorities as a function of interference occurring in each respective channel, where channels with a lower priority are preferably occupied relative to channels with a high priority when there are good propagation conditions; and taking into account a threshold value (CIRt), in particular the carrier/interference ratio (CIR), which is used in testing whether or not a channel is to be occupied; wherein the threshold value (CIRt) is a function of the priority (P) of the respective channel, where said function starts from a constant value and follows a course that decreases monotonically as the priority (P) becomes lower; and wherein a quantity that depends on an extent of the interference is averaged to increase or decrease the priority.
Claim 6
Dependent Claim
14 words
The process according to claim 3, wherein the averaging is performed by recursive filtering.
Claim 7
Dependent Claim
132 words
A process for dynamic channel allocation in mobile radio networks, said process comprising the steps of: establishing priorities for a plurality of individual channels; increasing or decreasing the priorities as a function of interference occurring in each respective channel, where channels with a low priority are preferably occupied relative to channels with a high priority when there are good propagation conditions; and taking into account a threshold value (CIRt), in particular the carrier/interference ratio (CIR), which is used in testing whether or not a channel is to be occupied; wherein the threshold value (CIRt) is a function of the priority (P) of the respective channel, where said function is a substantially continuous function which starts from a constant value and follows a course that decreases monotonically as the priority (P) becomes lower.
