Apparatus,method and computer program for communicating via a plurality of networks

摘要

Access control information is received from a first network, which is the device's serving network (500). The received access control information is stored as access control settings (505). A first connection is established via the serving network based on one or more of the access control settings (510). It is determined that the device's serving network has changed to a second network (515). At least a portion of the access control settings is replaced with default access control settings (520). The access control settings may comprise one or more packet-domain settings and one or more circuit-domain settings. The access control information may comprise Domain Specific Access Control (DSAC) and/or Paging Permission with Access Control (PPAC) information. The default access control settings may comprise access class barring (ACB) information.
