Embodiment Construction

[0020] Embodiments of the present invention will be described below based on the drawings.

[0021] refer to figure 1 A mobile communication system according to an embodiment of the present invention will be described. figure 1 A mobile communication system according to an embodiment of the present invention is shown. As shown in the figure, the mobile communication system 100 includes a UTRA (UMTS Terrestrial Radio Access, UMTS Terrestrial Radio Access) system 200 , an EUTRA (Evolved UTRA, Evolved UTRA) system 300 , and a mobile station (UE) 400 . In the mobile communication system 100 , the mobile station 400 can perform wireless communication with both the UTRA system 200 and the EUTRA system 300 . In addition, the UTRA system 200 and the EUTRA system 300 can be communicatively connected to each other. In the illustrated embodiment, only one mobile station 400 is shown, but typically, the mobile communication system 100 includes a plurality of mobile stations 400 . In a...

Abstract

This invention relates to a mobile station capable of communicating with first and second networks using different wireless access techniques. The mobile station comprises: a receiving unit for receiving, from the first network, broadcast information of the second network; a storing unit for storing the received broadcast information of the second network; and a pre-redirection information setting unit for setting pre-redirection information, which is included in a wireless connection request message, to a predetermined value when the broadcast information of the second network is stored in the storing unit.

Description

technical field [0001] The present invention relates to a mobile communication system, and more particularly, to a mobile communication system that provides wireless communication via a plurality of networks using different radio access technologies. Background technique [0002] In recent years, various radio access technologies (Radio Access Technology) have been developed, and wireless communication services generated by newly developed radio access technologies (RAT) have been continuously introduced. When a wireless communication service by a new wireless access technology is introduced, a wireless communication service by an existing wireless access technology and a wireless communication service by a new wireless access technology coexist. For example, there are UTRA (UMTS Terrestrial Radio Access, UMTS Terrestrial Radio Access) and EUTRA (Evolved UTRA, Evolved UTRA), which evolves UTRA, as radio access technologies, and mobile communication systems with UTRA networks...
