Document Type and Number:
Japanese Patent JP2696184
Kind Code:
B2
Abstract:
In personal communications systems, a wireless handset user is not generally aware of the quality of the radio link to the base station when a call is in progress. Novel mechanisms are disclosed by which the handset user is given up-to-date information concerning radio link parameters. According to the invention, the base station continuously analyzes the received signal of a handset and sends back to the handset a signal indicative of the link parameters. Upon receiving the signal, the handset informs the user by way of either processed sidetone or other indications.
