Patent ID: 7428409

Claim:
A method of obtaining user data to be transmitted to a network side having a switching system, the method comprising: receiving at a radio control base station first user data comprising a plurality of transport blocks transmitted from a same mobile terminal, based on an Iub frame protocol of a universal mobile telecommunication system (UMTS) standard, via a plurality of radio base stations: numerically expressing, for each of the plurality of transport blocks, a plurality of parameters of the Iub frame protocol respectively used when the radio base station transmits the user data; obtaining a value of an evaluation parameter indicating a communication quality for the each of the plurality of transport blocks, by adding the plurality of numerically expressed parameters, and generating; selecting at least one optimum transport block based on the obtained value of the evaluation parameter for the each of the plurality of transport blocks; and obtaining second user data to be transmitted to the network side, by combining the selected at least one optimum transport block.
