摘要：
A mobile communication method according to the present invention includes a step A in which, in location registration processing of a mobile station, an switch of a first communication scheme and an switch of a second communication scheme send a subscriber information server first information used to determine whether or not all coverage areas have a same capability of providing a telephony service by packet switching; and a step B in which, when a status inquiry request made upon receipt of a terminating-call signal destined for the mobile station is received from an application server, the subscriber information server determines based on the first information whether or not to make an inquiry at the switch of the first communication scheme or the switch of the second communication scheme about whether or not provision of the telephony service by packet switching is possible in an area where the mobile station is located.
