Multicast data transmission from a web server to client terminal devices using a wireless local area network

A method of data reception, comprising:

• receiving, by a client device, multicast data from a server via a wireless local area network (WLAN), wherein data objects in the data are identified by data object type and the data is multicast via separate logic channels in a bandwidth of the WLAN for each data object type, and the data objects are fragmented into multiple data packets providing with a header containing corresponding transmission parameters;
• detecting a logic channel identifier for each data packet;
• allocating the data packets between the logic channels followed by error correction of received data packets in each logic channel, wherein in case of a packet error, the client device repeats receiving each of the data packets for which an error is detected;
• and
• restoring the data objects from the data packets on the client device.

An apparatus for data reception, comprising a processor coupled to a memory, the memory holding instructions that when executed by the processor, cause the apparatus to perform:

• receiving multicast data from a server via a wireless local area network (WLAN), wherein data objects in the data are identified by data object type and the data is multicast via separate logic channels in a bandwidth of the WLAN for each data object type, and the data objects are fragmented into multiple data packets providing with a header containing corresponding transmission parameters;
• detecting a logic channel identifier for each data packet;
• allocating the data packets between the logic channels followed by error correction of received data packets in each logic channel, wherein in case of a packet error, the apparatus repeats receiving each of the data packets for which an error is detected;
• and
• restoring the data objects from the data packets in the memory.
