APPARATUS AND METHOD FOR CORDLESS INTERNET PROTOCOL

摘要

A mobile station (323) may register with a base set (301) to access a fixed line service, such as broadband IP network (315), to make and receive calls. When the mobile station (323) is within a radio coverage area of access point (313), it may seamlessly register itself and receive calls placed to a home phone number. Mobile station (323) may initiate a call using either its own MSISDN of the MSISDN of the base set (301), but not both. A second mobile station (327) registered with base set (301) may participate in the same call, acting as an extension line. In this manner, home base (301) provides a user cordless phone experience similar to having cordless extension phones connected to a PSTN line.
