| 摘要 |
To address the need for conveying data to a base site (110) and communication unit (104) without substantially introducing congestion or delay to the network used, the present invention provides two methods and a data gateway apparatus. The data gateway (116) upon receiving a data packet addressed to a communication unit (104), divides the data packet into data blocks and generates transmission data packets which can be transmitted from a base site (110) to the communication unit (104) in individual time slots. The transmission data packets, being smaller than the data packet, do not introduce substantial delay to an infrastructure network (114) and are conveyed over time to prevent congestion.
