Mobile communication terminal, incoming data detecting method and incoming data detecting program
First Claim
1. A mobile communication terminal that makes a wireless communication with at least one of a first base station offering a first service area and a second base station offering a second service area, comprising:
- a system information receiving unit for receiving, from the first base station or the second base station, system information including a paging indicator (PI) within a paging indicator channel (PICH) and a paging channel (PCH); and
a cell reselecting unit for executing a cell reselection process for switching from a wireless communication with the first base station to a wireless communication with the second base station if the mobile communication terminal fails to obtain local incoming information due to unsuccessful reception of the PCH, which is made by the system information receiving unit, after receiving a notification that incoming data exists by receiving the PI within the system information received by the system information receiving unit within the first service area.

Abstract
Included are a system information receiving unit for receiving, from a first base station or a second base station, system information including a PI within a PICH and a PCH, and a cell reselecting unit for executing a cell reselection process for switching from a wireless communication with the first base station to that with the second base station if a mobile communication terminal fails to obtain local incoming information due to unsuccessful reception of the PCH, which is made by the system information receiving unit, after receiving a notification that incoming data exists by receiving the PI within the system information received by the system information receiving unit within the first service area. Consequently, the mobile communication terminal and incoming data detecting method and program, which can securely receive incoming data even if the mobile communication terminal fails to receive the PCH although receiving incoming information with the PI.

5. Incoming data detecting method executed by a mobile communication terminal that makes a wireless communication with at least one of a first base station offering a first service area and a second base station offering a second service area, the method comprising:
-
receiving, from the first base station or the second base station, system information including a paging indicator (PI) within a paging indicator channel (PICH) and a paging channel (PCH) by a system information receiving unit of the mobile communication terminal; and executing by a cell reselecting unit of the mobile communication terminal a cell reselection process for switching from a wireless communication with the first base station to a wireless communication with the second base station if the mobile communication terminal fails to obtain local incoming information due to unsuccessful reception of the PCH, which is made by the system information receiving unit, after receiving a notification that incoming data exists by receiving the PI within the system information received by the system information receiving unit within the first service area.

6. A non-transitory recording medium having stored therein a program for causing a computer of a mobile communication terminal, which makes a wireless communication with at least one of a first base station offering a first service area and a second base station offering a second service area, to execute an incoming data detecting process comprising:
-
receiving, from the first base station or the second base station, system information including a paging indicator (PI) within a paging indicator channel (PICH) and a paging channel (PCH) by a system information receiving unit of the computer; and executing by a cell reselecting unit of the computer a cell reselection process for switching from a wireless communication with the first base station to a wireless communication with the second base station if the mobile communication terminal fails to obtain local incoming information due to unsuccessful reception of the PCH, which is made by the system information receiving unit, after receiving a notification that incoming data exists by receiving the PI within the system information received by the system information receiving unit within the first service area.
