Impacts of enabling NSAPI/SAPI/PFI re-mapping on PS Handover Performance
ثبت نشده
چکیده
The PS Handover mechanism is being standardized in TSG GERAN [3GPP TS 43.129]. The primary goal of this procedure is to enable real-time services in GERAN A/Gb mode, but the handover mechanism would be applicable also to other PS services. Due to strict Quality of Service requirements on low latency and packet loss, real-time packet-switched (PS) services require a minimal service interruption of the data transfer during cell change. PS handover is defined following the GSM circuit-switched handover principle of allocating radio resources in the target cell prior to changing cell, such that it fulfils the QoS requirements for real-time services in [3GPP TS 23.107].

Handover Key Management and Re-Authentication Problem Statement
This document describes the Handover Keying (HOKEY) re-authentication problem statement. The current Extensible Authentication Protocol (EAP) keying framework is not designed to support re-authentication and handovers without re-executing an EAP method. This often causes unacceptable latency in various mobile wireless environments. This document details the problem and defines design goals for ...
متن کاملThe Impacts of Signaling Time on the Performance of Fast Handovers for MIPv6
A Fast Handover protocol (FMIPv6) in IETF working group is proposed to reduce the handover latency in Mobile IPv6 standard protocol. The FMIPv6 proposes some procedures for fast movement detection and fast binding update to minimize the handover latency. Additionally, to reduce the lost packets caused by a handover, this protocol introduces buffers in access routers. However, the handover laten...

One of the most interesting 3G networks feature is their integration with the 2G networks. It provides seamless End to-End services. Current widely deployed 2G and 3G networks provide enabling interoperability. These mechanisms include Inter RAT idle mode reselection. Inter RAT dedicated mode reselection is used for PS (Packet Switching) services. The WLAN coverage on one hand provides an extra...

The ability to access information while on the move has become a necessity for most business users. The 3G cellular networks, like UMTS, promise to offer always on, ubiquitous connectivity to users with relatively high mobility, but with relatively low data rate. On the contrary WLANs offer much higher data rates but with low er mobility coverage. The complementary characteristics of the 3G and...
متن کاملNursing Handover Written Guideline Implementation: A Way to Improve Safe Performance of Nurses in Intensive Care Units
Background: In the health centers, clinical data is regularly transferred between health care personnel. The most widespread of these handoffs are the inter-shift nursing reports, which occur several times in a day and could facilitate patient care plan, patient safety and continuity of care. But previous studies and clinical experience have indicated that there is no program for this major pur...
