METHOD OF BARRING NETWORK ACCESS, MOBILE DEVICE AND PROCESSOR

摘要

When a network is requiring access barring, a mobile device determines whether a reference value broadcasted to the mobile device indicates a value determining that an access is denied regardless of a numerical value generated by the mobile device, or indicates a value having a possibility that an access of a certain mobile device is denied while an access of another mobile device is allowed. In the latter case, the mobile device determines appropriateness of an access by performing predetermined processing using the reference value as a value to be checked for a relationship with a numerical value generated by the mobile device when the mobile device does not have a special type access class, and uses a value enabling allowance of an access without performing the predetermined processing as a value for determining appropriateness of an access when the mobile device has the special type access class.

主权项

1. A method of barring a network access performed in a mobile device connectable to a radio access network and capable of establishing a communication session, wherein
each mobile device connectable to the radio access network belongs to at least one of access classes, the access classes include a special type access class and a normal type access class, broadcast information to be broadcasted to each mobile device from the radio access network includes barring information for barring an access to the network, the barring information includes first barring information for designating whether a mobile device in each access class is subjected to access barring, and second barring information indicating a value serving as a reference for determining appropriateness of an access according to a relationship with a numerical value generated by each mobile device, and possible values of the reference indicated by the second barring information includes a first type value having a possibility that, depending on numerical values generated by mobile devices subjected to access barring, an access of a certain mobile device is denied while an access of another mobile device is allowed, and a second type value other than the first type value, the mobile device if the reference indicated by the second barring information is the first type value, determines appropriateness of an access or appropriateness of a session establishment by performing predetermined processing using a value indicated by the second barring information as a value to be checked for a relationship with the numerical value generated by the mobile device itself when not having the special type access class as an access class to which the mobile device itself belongs, or uses a value enabling allowance of an access or allowance of a session establishment without performing the predetermined processing as a value for determining appropriateness of an access or appropriateness of a session establishment when having the special type access class; and when the reference indicated by the second barring information is the second type value, determines the appropriateness of an access or the appropriateness of a session establishment based on designation by the first barring information when having the special type access class as an access class to which the mobile device itself belongs, and determines that an access is denied or a session establishment is denied when not having the special type access class.
