Problems solved by technology

[0006] While the above does provide seamless and non-oscillating handovers, interactive real-time services that are very delay-sensitive, such as voice calls and media streaming over the Internet, have stringent performance requirements for end-to-end delay and packet loss, thus Enhanced requirements for mobility-enabled procedures such as handover procedures

Embodiment Construction

[0014] The following examples are exemplary. Although this specification may refer to "an", "one" or "certain" embodiments in several places, this does not necessarily mean that each such reference refers to the same (one or multiple) embodiments, nor does it imply that a feature applies to only a single embodiment. Single features of different embodiments may also be combined to provide other embodiments.

[0015] The present invention is applicable to any device that supports handover procedures triggered by announcement based movement detection in a mobility enabled communication environment. The communication environment comprises access technologies supporting mobility of end user terminals and / or access technologies supporting mobility of access entities providing end users (fixed or mobile) with access to communication services, and / or an access technology that supports the mobility of other access entities. Various system configurations to which various communicatio...

Abstract

In an advertisement based movement detection a mobile node adjusts its advertisement waiting period when it receives an advertisement from a serving access entity of the mobile node and an advertisement from another access entity. By adjusting the waiting period a timely handover may be performed.

Description

[0001] related application [0002] This application claims priority from US Provisional Application No. 61 / 136.733, which is hereby incorporated by reference in its entirety. technical field [0003] The present invention relates to handover in mobile communication systems, and more particularly to handover decisions in overlapping coverage areas, the handover decision involving the selection of an access entity, ie whether to trigger a handover. Background technique [0004] The evolution of communication technologies has introduced a wide variety of different access technologies, both wireless and wired, mobile networks and multi-mode user terminals that enable access to services through different access technologies. Beyond heterogeneous networks, end users want to access their services at any time while maintaining freedom of movement and uninterrupted access. This requires seamless handover - within a network, between homogeneous networks (ie, networks using the same ...
