Abstract
The Enhanced General Packet Radio Service (E-GPRS) has been standardized to improve the data transport efficiency and data rates in GSM/GPRS air interface. GPRS relies on a static mapping of resources between the Abis and the air interface (made by provisioning). This current approach does not provide enough resources on the Abis interface to transport traffic from the air interface when the coding scheme has a data rate superior to 16kbits/s. E-GPRS will then require more resources on the Abis. This paper investigates the performance of two dynamic allocation policies for the Abis interface for E-GPRS systems. The first strategy is called micro circuit strategy. The second strategy is referred as buffered strategy. Performance evaluations are performed by computer simulation.
