The invention is a method and apparatus for providing an Alert With Information Message signal between a mobile switching center (36) and a base station (34) in a cellular communication system. The invention recognizes that current provisions of the IS-634 standard lack support for certain required functionality on the interface between a mobile switching center (36) and a base station (34), or the A-Interface. An Alert With Information Message signal is introduced on the A-Interface to support the required functionality. Introduction of the Alert With Information Message provides support for reliable call processing on the A-Interface for the call waiting procedure, the hard handoff procedure, and the resolution of a glare condition. A message generator (38) in the mobile switching center (36) generates the Alert With Information Message, which is transmitted to message receiver (40) in the base station (34) when needed.

L'invention concerne un procédé et un dispositif servant à produire un signal de message d'alerte avec information entre un centre de commutation mobile (36) et une station de base (34) dans un système de communication cellulaire. L'invention reconnaît que les dispositions de la norme IS-634 sont faibles en ce qui concerne un certain caractère fonctionnel nécessaire de l'interface entre un centre de commutation mobile (36) et une station de base (34), ou de l'interface-A. Un signal de message d'alerte avec information est introduit sur l'interface A afin d'assister ce caractère fonctionnel nécessaire. L'introduction de ce message d'alerte avec information constitue une assistance au traitement fiable d'un appel sur l'interface A pour la procédure d'attente d'appel, la procédure de transfert permanent et la résolution d'un état d'éblouissement. Un générateur de message (38) dans le centre de commutation mobile (36) génère le message d'alerte avec information, qui est transmis au récepteur de message (40) de la station de base (34) si nécessaire.
