Abstract
A base station in a mobile communication system, which enables maintenance of a normal transmission interval of data output, and effective usage of bands, is disclosed. Quality checking part provided in a base station BS rejects those data which the base station has failed to receive in a good receiving state. Instead, quality checking part inserts an invalid data shorter than a valid data. In this way, a vacancy is created in the relevant band or slot correspondingly to a difference between the length of a valid data length and the length of an invalid or dummy data length. This vacant band can be utilized by another user, resulting in that the utilization efficiency of link between the base station and an MSC (Mobile Switching Center) is improved.
Claims8
A base station in a mobile communication system having a wire network adopting an asynchronous transfer mode (ATM);
- comprising
- a quality checking part for performing quality check of user data received from a transmitting mobile terminal, and for rejecting those data which have failed in satisfying a predetermined quality, and for inserting an invalid data shorter than a valid data;
- and
- a CPS packet generating part for generating a CPS packet.
A base station in a mobile communication system having a wire network adopting an asynchronous transfer mode (ATM) and an asynchronous transfer mode adaptation layer 2 (ATM Adaptation Layer 2:
- AAL2);
- comprising
- a quality checking part for processing wireless communication quality information, for performing quality check of user data received from a transmitting mobile terminal, and for rejecting those data which have failed in satisfying a predetermined quality;
- and
- a CPS packet generating part for generating a CPS packet, by adding a wireless communication quality information, a wireless communication frame number and a valid/invalid identifier to that user data which has satisfied a predetermined quality.
A base station in a mobile communication system having a wire network adopting an asynchronous transfer mode (ATM) and an asynchronous transfer mode adaptation layer 2 (ATM Adaptation Layer 2:
- AAL2);
- comprising
- a quality checking part for performing quality check of user data received from a transmitting mobile terminal, and for rejecting those data which have failed in satisfying a predetermined quality;
- a CPS packet generating part for generating a CPS packet, by adding a wireless communication quality information, a wireless communication frame number and a valid/invalid identifier to that user data which has satisfied a predetermined quality;
- a CPS packet receiving part for extracting data for quality check to be used for quality check of said user data;
- and
- an intra-base station controlling part for notifying said extracted data for quality check to said quality checking part;
- wherein said quality checking part preserves said quality check data, and utilizes said data for quality check of said user data;
- wherein said quality checking part outputs an invalid data generated notice to said CPS packet generating part, when said quality checking part has rejected user data from said transmitting mobile terminal, and
- said CPS packet generating part receives said invalid data generated notice, generates an invalid data shorter than a valid data, and CPS packetize said wireless communication frame number and said valid/invalid identifier received from said quality checking part as well as said generated invalid data.
