Abstract
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.
Claims6
A data gateway comprising:
- a first network interface processor adapted for receiving data from a first network;
- a second network interface processor adapted for transmitting a transmission data packet and control information via a second network to a base site;
- and
- a communication processor, coupled to the first network interface processor and the second network interface processor, adapted for dividing the data into a plurality of data blocks, determining a quantity of the plurality of data blocks that can be transmitted by the base site in a time slot, generating the transmission data packet comprising the quantity of data blocks determined, the data blocks being selected from the plurality of data blocks, generating the control information that instructs the base site to transmit the transmission data packet in a time slot based on a sequence identifier, and requesting the second network interface processor to transmit the transmission data packet and control information to the base site.
