Method and apparatus for optimized assignment of abis transmission resources based on dynamic statistical time division multiplexing

A packet control unit comprising an entity of packet control unit, characterized in further comprising a transmission resource assigning unit connected to the entity and a TRX load decision and adjusting unit connected thereto,

• the transmission resource assigning unit for assigning Abis transmission resources to a TRX having GPRS/EGPRS services and performing optimized assignment of bandwidth of transmission resources based on current using status of the Abis transmission resources and a predicted flow required on the TRX;
• the TRX load decision and adjusting unit for determining and predicting flow load of the TRX in real time and adjusting assignment of bandwidth of transmission resources on the TRX based on changes in load on the TRX.

A method for controlling optimized assignment of Abis transmission resources in a packet control unit, comprising:

• pre-assigning step for assigning Abis transmission resources with optimal bandwidth to a TRX having GPRS/EGPRS based on general using status of transmission resources;
• TRX load decision and adjusting step for determining and predicting flow load of the TRX in real time and adjusting assignment of bandwidth of transmission resources on the TRX based on changes in load on the TRX;
• re-assigning step for performing optimized assignment of transmission resources based on the adjusted bandwidth of Abis transmission resources on the TRX.

A base transceiver station, comprising:

• an entity of base transceiver station, characterized in further comprising a monitoring module for monitoring position of one or more sub-channels of actual transmission resources and bandwidth of transmission resources assigned to a TRX.

A base station controller, comprising an entity of base station controller, characterized in further comprising a connection means,

• The connection means is for interconnecting Abis transmission resources and BSC-PCU transmission resources based on Abis transmission resources assigned by a packet control unit, and forwarding correspondence between the Abis transmission resources and a TRX from the packet control unit to a monitoring module of a BTS to inform the BTS that the Abis transmission resources have been assigned to a TRE mapped to the TRX.
