QoS in GPRS
Mobile telephony has been for many years the most popular application supported by mobile systems such as the Global System for Mobile communications (GSM). Recently, the use of mobile data applications such as the GSM Short Message Service (SMS) has gained popularity. However, the GSM system can only support data services up to 9.6 kbit/s, circuit switched. The General Packet Radio Service (GP...
متن کاملQoS Provisioning Mechanisms in GPRS Networks
This paper presents three different mechanisms to provide Quality of Service (QoS) to General Packet Radio Service (GPRS) users. These mechanisms include a Call Admission Control (CAC), a Radio Resource Reservation and Scheduling in the radio interface. Video, voice and data integration are expected by mobile users. However, these media have different QoS requirements in terms of bandwidth and ...
متن کاملQoS provisioning over GPRS wireless mobile links
The General Packet Radio Service (GPRS) offers performance guaranteed packet data services to mobile users. This paper presents a guaranteed qualityof-service (QoS) provisioning scheme over GPRS wireless mobile links by proposing a guaranteed QoS media access control (GQ-MAC) protocol and an accompanying prioritized handoff call admission control (PH-CAC) protocol to maintain QoS guarantees und...
متن کاملQoS support in the UMTS/GPRS backbone network using DiffServ
The Universal Mobile Telecommunications System (UMTS) has a number of service classes that require end-to-end QoS support. This requirement imposes on the design of the UMTS backbone bearer service as a part of the UMTS hierarchical QoS architecture. This paper presents a methodology of provisioning QoS in the UMTS backbone network based on the Differentiated Services (DiffServ) model, a relati...
متن کاملQoS-Based Dynamic Channel Allocation for GSM/GPRS Networks
Efficient channel allocation is important for meeting the quality of service (QoS) requirements of both GSM voice calls and GPRS packets in integrated GSM/GPRS networks. In this paper, we propose a new dynamic channel allocation scheme with guard channel, channel deallocation/re-allocation for voice call and packet queue for GSM/GPRS networks. An analytic model with general GPRS channel require...
