Handover of packet-switched services in GERAN A/Gb mode

Due to strict quality of service requirements on low latency and packet loss, real-time packet-switched (PS) services require a minimal service interruption on the data transfer during cell change. Existing GPRS cell change mechanisms with network assisted cell change (NACC) enable a theoretical minimum service interruption of 0.7-1.2 second, while real-time PS services of conversational class do not tolerate a service gap longer than 0.15 seconds. Therefore in GERAN A/Gb mode a PS handover procedure is being designed to allow for conversational services in GPRS that would improve the network performance for any PS service. PS handover follows the GSM circuit-switched handover principle of allocating radio resources in the target cell prior to changing cell. In this paper PS handover procedure is described and its performance evaluated in terms of service interruption by means of network simulations

ARQ considerations for the new GSM/EDGE flexible layer one

A major enhancement of the GSM/EDGE Radio Access Network (GERAN) is the Flexible Layer One (FLO) concept, due to he introduced in Release 6 nf the 3GPP standards. FLO greatly simplifies the introduction of new services to the GERAN system, allowing for “tailor-made” provision of any given Quality of Service (QnS), significantly enhancing GERAN’s flexibility, and ensuring it will evolve on par with other 3G systems. In the GERAN Iu mode, FLO supports data transfer in transparent, unacknowledged and acknowledged RLC (Radio Link Control) modes. In the latter mode, the RLC applies backward error correction (BEC) through an ARQ (Automatic Repeat reQuest) mechanism Considering ARQ mechanisms, Hybrid Type I1 ARQ (aka. incremental redundancy) is a very efficient technique that requires a close interaction between the retransmission protocol at the RLC layer and the channel encoderldecoder at the physical layer. This paper first introduces the concept of FLO, and then describes how hybrid type I1 ARQ can he implemented in the FLO physical layer. Finally, we present the performance gains possible by introducing incremental redundancy to FLO, especially when compared to the performance of Chase combining.

Radio resource control for GSM/EDGE Radio Access Network (GERAN)-inter radio access technology and inter-mode procedures

The 3GPP Release 5 will specify a GSM/EDGE Radio Access Network (GERAN) which can connect to 3G mobile core network (CN) through the Iu interface. The new architecture implies significant modifications to the GERAN radio protocols. This paper focuses on radio resource control (RRC) procedures, especially on the new defined inter radio access technology procedures between GERAN Iu mode and UMTS Terrestrial Radio Access Network (UTRAN) or inter-mode procedures between GERAN Iu mode to GERAN A/Gb mode in Release 5.
