Problems solved by technology

However, even when the wireless communication terminal that is not assigned the QoS rate of the maximum speed and connected to the base station transitions to the standby state, and thereafter connects to the base station again, the QoS rate of the maximum speed cannot be acquired

Embodiment Construction

[0048] Preferred embodiments of the present invention will now be described with reference to the accompanying drawings.

[0049] figure 1 is a block diagram showing the configuration of a wireless communication terminal according to the present invention. The wireless communication terminal (cellular phone) 100 of the present invention uses a shared antenna 110, and is designed to operate between the CDMA2000lx communication system (hereinafter referred to as "1x system") and the CDMA2000lx EV-DO communication system (hereinafter referred to as "EV-DO system") ) to perform data communication with the base station of each communication system. The CDMA2000lx EV-DO communication system not only corresponds to CDMA2000lx EV-DO Rev.0, but also corresponds to CDMA2000lx EV-DOR Rev.A.

[0050] The wireless communication terminal 100 includes an RF unit 120 for 1x, an RF unit 130 for DO, an RF control unit 140, a system control unit 150, an input unit 160, a display unit 170, a s...

Abstract

The present invention discloses a wireless communication terminal (100) that includes a handoff determination unit (150a) for determining whether or not to perform handoff based on a measuring result of quality of a signal transmitted from a base station (200) and a handoff threshold, a QoS rate readjustment unit (150b) for readjusting a QoS rate for a base station to which handoff is performed when handoffis performed while a QoS is being set, and a handoff threshold setting unit (150c) for setting a handoff threshold which facilitates handoff when a QoS rate is lowered before and after handoff as a result of readjustment by the QoS rate readjustment unit (150b) and for setting a handoff threshold which impedes handoff when the QoS rate is raised.

Description

[0001] Cross References to Related Applications [0002] This application claims priority and benefit from Japanese Patent Application No. 2006-294229 filed on October 30, 2006 and Japanese Patent Application No. 2006-294261 filed on October 30, 2006, the entire contents of which are incorporated herein by reference. technical field [0003] The present invention relates to a wireless communication terminal capable of transmitting a QoS (Quality of Service) setting request to a base station with a call connection request and starting communication at a QoS rate determined in response to the QoS setting request; The connection request transmits a QoS (Quality of Service) setting request from the wireless communication terminal to the base station, and allows the wireless communication terminal to start communication at a QoS rate determined in response to the QoS setting request. Background technique [0004] A conventional mobile communication system using a CDMA (Code Divis...
