QoS in 3G Wireless Networks 2G networks such as Global System for Mobile Communications (GSM)/code division multiple access (CDMA) have essentially only one QoS option, viz., speech at full-rate coding in GSM. Subsequently, a half-rate service was introduced, thus offering a new QoS. In ... [full story]

Two-Phase Activation Model Activation of a service flow proceeds in two phases: admit first, then activate. This is facilitated via an authorization module in the BS, which approves or rejects a request regarding a service flow. The authorization module can activate a service flow ... [full story]

Dynamic Service Establishment The 802.16 standard provides a signaling function for dynamically establishing service flows and requesting QoS parameters. There are three types of control messages for service flows: Dynamic service activate (DSA)—Activate a service flow Dynamic service change (DSC)—Change an existing service flow Dynamic service ...
