Establishing mobile connectivity conditions for mobile subscriber units in a wireless communication networks

摘要

An apparatus and method for establishing mobile connectivity conditions for mobile subscriber units in a wireless communication network includes scanning, by each mobile subscriber unit, for candidate access points and affiliated channels for roaming, whereupon the unit can roam from an originating access point to one of the candidate access points on an affiliated channel for roaming. A link record in the mobile subscriber unit is used for recording an entry including the originating access point, the candidate access point, the affiliated channel for roaming, and a handoff experience value. The link record can be used upon subsequent roaming of the unit to attempt a self-devised handoff without further scanning for access points and affiliated channels. Link records can be shared between mobile subscriber units to speed up map building of link records.

主权项

1. A method for establishing mobile connectivity conditions for mobile subscriber units in a wireless communication network, the method comprising the steps of:
scanning, by each mobile subscriber unit, for candidate access points and affiliated channels for roaming; roaming from an originating access point to one of the candidate access points on an affiliated channel for roaming; recording, in a link record in the mobile subscriber unit, an entry including an identity of the originating access point, an identity of the candidate access point, the affiliated channel for roaming, and a handoff experience value; and using the link record upon subsequent roaming to attempt a self-devised handoff without further scanning for access points and affiliated channels, wherein, in the recording step, the handoff experience value is quantified using parameters including an indicator as to how well the handoff was completed, and the using step uses the entry having a highest handoff experience value for the self-devised handoff attempt.
