Problems solved by technology

[0005] At this time, once the radio resource for connection is secured in the cell of the first communication method, a connection setting is attempted in the cell of the second communication method, so the radio resources in the cell of the first communication method are wasted, In addition, there is a problem that the time until the connection is set in the cell of the second communication method becomes longer

Embodiment Construction

[0019] (Configuration of the mobile communication system according to the first embodiment of the present invention)

[0020] refer to Figure 1 to Figure 6 , the configuration of the mobile communication system according to the first embodiment of the present invention will be described.

[0021] like figure 1 As shown, the mobile communication system according to this embodiment has a coverage area formed by cells of the UMTS scheme (first communication scheme) and a coverage area formed by cells of the LTE scheme (second communication scheme).

[0022] In the mobile communication system according to the present embodiment, the mobile station UE preferentially waits in a UMTS-based cell from the standpoint of the coverage area and the available communication services.

[0023] like figure 2 As shown, the mobile station UE includes a standby processing unit 11 , a determination information storage unit 12 , and an RRC connection setting unit 13 .

[0024] The standby pro...

Abstract

A mobile communication method according to the present invention includes a step of a mobile station UE transmitting a connection setup request signal containing a radio access capability of the mobile station eNB to a radio network controller RNC of a UMTS scheme, upon detecting a predetermined trigger while camping on in a cell of the first communication scheme, a step of the radio network controller RNC of the UMTS scheme transmitting an instruction signal for instructing setup of a connection in a cell of an LTE scheme to the mobile station UE, in a case where the radio access capability of the mobile station UE is contained in the received connection setup request signal, and a step of the mobile station UE setting up the connection in the cell of the LTE scheme in response to the received instruction signal.

Description

technical field [0001] The present invention relates to a mobile communication method, a mobile station and a network device. Background technique [0002] In a WCDMA mobile communication system, when a mobile station UE attempts to set up a connection in a specific cell, it sends an "RRC Connection Request (RRC Connection Request : RRC connection request (connection setup request signal)), the network device secures radio resources for the connection and notifies the mobile station UE, thereby establishing the "RRC Connection Setup step (RRC Connection Setup procedure) for setting the connection. Setup: RRC connection establishment)". [0003] In the existing WCDMA mobile communication system, the mobile station UE is equipped with multiple communication systems such as LTE (Long Term Evolution), UMTS (Universal Mobile Telecommunications System) and GSM (Global System for Mobile Communications). In the case of a capability corresponding to a communication method (Radio Ac...
