TLDR
In this article, a handover request message from the mobile station to the serving base station is transmitted when it is detected that a performance of a handoff is necessary; and transmitting an handover indication message containing handover cancel information to the base station when the mobile stations determines a cancel of the handover while the mobile unit is being handed over to one or more target base stations by the service provider.Abstract:
Disclosed is a method for enabling a mobile station existing in a serving cell area to perform a handover procedure in a broadband mobile communication system including the mobile station, a serving base station providing a service to the mobile station, and one or more target base stations containing at least one target cell area overlapping with the serving cell area occupied by the serving base station. The method includes transmitting a handover request message from the mobile station to the serving base station when it is detected that a performance of a handover is necessary; and transmitting a handover indication message containing handover cancel information to the serving base station when the mobile station determines a cancel of the handover while the mobile station is being handed over to one or more target base stations by the serving base station.read more

Mobile station assisted soft handoff in a CDMA cellular communications system
TL;DR: In this article, a mobile station monitors the signal strength of pilots and reports the measured signal strength to a system controller via the base station through which it is communicating and terminates communication through the corresponding base station while communications through the other base station or base stations continue.
Patent
Transfer of security association during a mobile terminal handover
TL;DR: In this paper, the authors propose a challenge/response procedure for authentication during a communication handover event in a radio communications system such as IEEE 082.11 or HIPERLAN, where the existing security association between a mobile terminal and a wireless communication network is maintained.
