Abstract
Methods of reconfiguring a cell regarding the number of signaling channels in relation to the number of traffic channels. Each signaling channel (SDCCH/8) contains a number of dedicated control channels (SDCCH), wherein a number of dedicated control channels are included in a basic configuration of control channels. If the channel utilization indicates that a basic configuration of control channels is congested for more than a certain percentage of time, a dedicated control channel is added to the basic configuration. If it is determined that the basic configuration, less one control channel, is congested less than a certain percentage of time then a control channel is removed from the basic configuration.
Claims5
A method of reconfigurating a cell in a cellular mobile radio system in order to avoid congestion by converting a traffic channel to a dedicated control channel or vice versa, wherein each cell includes a basic number of allocated control channels and a number of traffic channels and where no dynamic reconfiguration on a short term basis is made, comprising the steps of:
- a) investigating whether the total number of allocated control channels in a cell exceeds a basic number of such channels in the cell;
- b) if so, adding an extra control channel to the basic number of such channels;
- while if not
- c) investigating whether the total number of allocated control channels exceeds a reduced number of said basic number of allocated control channels, and if so
- d) removing at least one of said dedicated control channels from said basic configuration.
A method of reconfiguring a cell in a cellular mobile radio system in order to avoid congestion by converting a traffic channel to a dedicated control channel or vice versa, wherein each dedicated control channel includes number of allocated control channels and wherein each cell includes a basic number of allocated control channels and a number of traffic channels (TCH) and where no dynamic reconfiguration on a short term basis is made, comprising the steps of:
- a) investigating whether there is congestion on allocated control channels more than a determined percentage of a certain time, and if so
- b) adding an extra dedicated control channel to the basic configuration of allocated control channel while if not,
- c) investigating whether the total number of allocated control channels is greater than a reduced number of the basic number of allocated control channels for a certain percentage of said time, and if so
- d) removing one of said dedicated control channels from the basic configuration of allocated control channels.
A method of reconfiguring a cell in a cellular mobile radio system in order to avoid congestion when converting a traffic channel to a dedicated control channel or vice versa, wherein each dedicated control channel includes a number of allocated control channels and wherein each cell includes a basic number of such allocated control channels and a number of traffic channels and where a dynamic reconfiguration of the allocated control channels on a short term basis is made, comprising the steps of:
- a) investigating whether the total number of allocated control channels in a cell exceeds a basic number of such allocated channels in the cell during a certain percentage of a certain time and if so;
- b) adding an extra dedicated control channel to the basic number of such allocated channels;
- while if not,
- c) investigating whether the total number of allocated control channels exceeds a reduced number of said basic number of allocated control channels during a certain percentage of said time and if so,
- d) removing one of said dedicated control channels from said basic number of allocated control channels.
