Mobile station apparatus, base station apparatus, and mobile communication system

摘要

A mobile station (MS) includes a first circuitry configured to: select a cell by a cell selection procedure started by the MS, in a case where a radio link failure is detected, wherein said selecting based is on: a criteria of the cell selection procedure; information, used for indicating access restrictions of the MS, the information broadcasted on each cells; and an access class of the MS, wherein the access class being either: a first access class applied for an emergency call, or other access classes applied for other calls; and treat, in a case where the radio link failure is detected upon communication of the first access class, the selected cell as an appropriate cell even in a case where the selected cell is a cell belonging to a first base station not registered in the list; and a second circuitry configured to access the appropriate cell.

主权项

1. A processing method performed in a mobile communication system, the processing method comprising:
restricting an access for a normal call from a mobile station apparatus in a case where a cell of a first base station apparatus is not registered in a list of the mobile station apparatus; selecting a cell by a cell selection procedure started by the mobile station apparatus, in a case where a radio link failure is detected, wherein
said selecting is based on:
a criteria of the cell selection procedure;information, used for indicating access restrictions of the mobile station apparatus, the information broadcasted on each cells; andan access class of the mobile station apparatus, wherein
the access class being either: a first access class applied for an emergency call, or other access classes applied for other calls; and treating, in a case where the radio link failure is detected upon communication of the first access class, the selected cell as an appropriate cell even in a case where the selected cell is a cell belonging to the first base station apparatus not registered in the list; and accessing the appropriate cell.
