Embodiment Construction

[0032] (Structure of the mobile communication system according to the first embodiment of the present invention)

[0033] refer to Figure 1 to Figure 4 , the configuration of the mobile communication system according to the first embodiment of the present invention will be described.

[0034] The mobile communication system according to the present embodiment is a mobile communication system based on the LTE Rel.9 scheme.

[0035] Such as figure 1 As shown, in the mobile communication system according to this embodiment, the radio base station eNB transmits broadcast information, specifically transmits information including restriction information of the Rel.8 scheme of LTE or restriction information of the Rel.9 scheme of LTE (SSAC restriction information). SIB2.

[0036] figure 2 An example of SIB2 including restriction information (SSAC restriction information) of the LTE Rel.9 scheme is shown.

[0037] Such as image 3 As shown, the mobile station UE in this embod...

Abstract

A wireless base station (eNB) performs access regulation control with respect to an "MMTel originating call" even if transmission of SSAC regulation information in LTE Rel.9 format is not possible. A mobile station (UE) wherein an AS layer function (10) is provided with: a report information receiving section (11) for receiving, from the wireless base station (eNB), report information which includes first regulation information used in a mobile communication system in LTE Rel.8 format; an adjustment section (13) for generating, on the basis on the AC of the mobile terminal (UE) and the first regulation information, second regulation information used in a mobile communication system in LTE Rel.9 format; and a notification section (14) for notifying the second regulation information to an MMTel / IMS layer function (30). The MMTel / IMS layer function (30) is provided with a determination section (24) for determining on the basis of the second regulation information whether or not transmission processing can be performed.

Description

technical field [0001] The present invention relates to mobile stations. Background technique [0002] In the mobile communication system specified in 3GPP, each mobile station UE (User Identity Module (USIM)) has one of AC (Access Class) 0-9. [0003] In addition, a special mobile station UE (USIM) used by a network operator, the police, or government officials may have AC11~15. Hereinafter, AC11 to AC15 are referred to as “special ACs (Special ACs)”. In addition, AC10 is an AC for emergency calls, and is an AC that is not owned by the mobile station UE (USIM) and is used when calling a 110 number or a 119 number, or the like. [0004] Figure 11 An example of an access restriction control method in the Rel.8 scheme of LTE (Long Term Evolution) is shown. [0005] Such as Figure 11 As shown, in the Rel.8 mode of LTE, the mobile station UE is based on the call type of the incoming response call or the emergency call or the outgoing call or the signaling call, and also acc...
