Method and apparatus to control visited network access for devices

摘要

Methods and apparatuses are provided that facilitate controlling device access to one or more restricted groups of access points in a visited network. An indicator can be provided by a home network that specifies whether a device registering with a visited network is allowed to access restricted groups in the visited networks. If so, the visited network can request restricted group subscription information for the device. Additionally or alternatively, the device can control whether restricted groups are displayed for selecting access points based on one or more indicators regarding whether the device is allowed to access restricted groups in visited networks.

主权项

1. A method for determining a set of closed subscriber group (CSG) cells to display, comprising:
detecting signals from one or more CSG cells; receiving one or more indicators that specify whether access is allowed to CSGs in one or more visited networks, wherein the one or more indicators specify whether access is generally allowed to CSGs in visited networks, or whether access is allowed to CSGs in one or more specific visited networks; determining whether to display in a list of CSGs an identifier of one or more CSGs related to the one or more CSG cells based at least in part on the one or more indicators; suppressing the display of the identifier of the one or more CSGs in the list of CSGs when the one or more indicators specify that access is not generally allowed to the CSGs in visited networks; and displaying the identifier of the one or more CSGs in the list of CSGs when the one or more indicators specify that access is generally allowed to the CSGs in visited networks or when the one or more indicators do not specify that access is generally not allowed to the CSGs in the visited networks.
