Abstract

Most applications/transport protocols (i.e. TCP) were designed for wireline networks and stationery hosts. When operating in a wireless environment, each of these applications has its unique require- ments. By having a layer 2 (wireless channel) that does not adapt to each application's individual needs, system as well as application level perfor- mance decrease.

 METHOD FOR PROVIDING QOS TO MOBILE USER'S DATA APPLICATIQN

by Mouayad Albaghdadi and Karen Brailean

1. Detecting the type of ,application accessing the network during the start of a session. This type of information is usually not readily available at the layer 2 level and needs to be provided.

2. Classifying the application based on its type. The classification criteria would include parameters such as: delay sensitive/insensitive, type of transmission (inbound/outbound) or interactive, circuit vs. packet switched service. Refer to Table 1 for a sample of some known applications. This table would be stored where it can be accessed by layer 2.

3. Identify the resources needed to be reconfigured. This is a network dependent process where large communication networks have many parameters and resources that can be fine tuned.

  As an example, we will consider the iDEN vation Aloha access scheme with acknowledgments packet data protocol. iDEN is a Time Division at the Logical Link Control (LLC) layer for reliable Multiple Access wireless communication system communication. The acknowledgments are given that carries dispatch, interconnect calls, paging, cir- priority over other data sent, but they are not sched- cuit data, packet data, and short messages. The uled; so they may wait before they can be packet dam protocol uses a queued contiguous reser- transmitted.
