Abstract: A wireless communication system serves User Equipment (UE) over external wireless networks. A provisioning system transfers a UE Identity (ID), network ID, and home policy for the UE to a network controller. The provisioning system transfers the network ID and a home rating group to a rating system. The network controller receives the UE ID and network ID from an external network element and transfers the home policy to the external network element. The external network element serves the UE based on the home policy and transfers external usage data to a rating system. The rating system translates the network ID into the home rating group and rates the external usage data using the home rating group. The rating system transfers the UE ID and home-rated usage data to a billing system. The billing system charges for the external network element service using the home-rated usage data.

Abstract: A method is provided for parsing a configuration file. The method comprises determining whether an element in a sequence of configuration file elements is a type of element expected at the configuration file element's position in the sequence; when the configuration file element is not the expected type, consulting a set of rules for handling unexpected configuration file elements; and following a rule in the rule set. The rules cause different actions to be taken at a given position in the configuration file at different times of executing the method for parsing. One of the rules specifies that subsequent configuration file elements in the sequence are to be analyzed and, if at least one subsequent configuration file element is an expected type, the at least one subsequent configuration file element is to be considered valid and is to be parsed in a manner appropriate for the subsequent configuration file element.

Abstract: A computer program and method that allows direct access and modification of the data tables (12) in voice-over-i.p. local routing switches (10) so that administrators can more easily modify data and/or supplement data therein. The method and computer program permits an administrator to view a list of voice-over-i.p. local routing switches; select a switch from the list; view a list of data tables for the selected switch; select a data table from the list; search for and retrieve information in the data table; modify the information; and then upload the modifications to the switch by sending the modifications to an interface on the switch.
