Patent ID: 8670391

Claim:
A channel allocation method comprising steps of: measuring periodically a load of each available channel and a difference of the load between two available channels; receiving a message requesting a signal bearer setting from a mobile communication terminal through a connected channel; when the message requesting the signal bearer is received, checking whether the difference in the load between the connected channel and another channel exceeds a first set point value; converting the connected connection of the mobile communication terminal to the another channel if the difference in the load exceeds the first set point value; receiving a message requesting a traffic bearer setting from the mobile communication terminal through the connected channel; when the message requesting the traffic bearer is received, checking whether the difference in the load between the connected channel and another channel exceeds a second set point value; converting the connected connection of the mobile communication terminal to the another channel if the difference in the load exceeds the second set point value; providing data to the mobile communication terminal through one of the connected channel and the another channel; checking whether a difference in the load between the channel providing the data and another channel exceeds a third set point value; selecting at least one mobile communication terminal among a plurality of mobile communication terminals connected to the channel providing the data if the difference in the load exceeds the third set point value; and converting the connected channel of the selected at least one mobile communication terminal to the another channel if the difference in the load exceeds the third set point value.
