Abstract: A method and system for applying policies to services is provided. An embodiment includes a method for applying services wherein a request from a subscriber for a particular service is received. The request is compared with a policy to ascertain whether or not access to the particular service is permitted, and, if permitted, if there are any restrictions or limitations to that access.

Abstract: In one aspect of the disclosure, a method of delivering content to a portable electronic device is provided that comprises receiving a request for content; determining a subscription level for a subscriber of the portable electronic device; determining, based on the subscription level, whether to deliver supplementary content with the content; and, if delivery of the supplementary content is to be effected then determining a method of delivery of the content; determining a method of delivery of the supplementary content; determining the supplementary content; and delivering the content and the supplementary content.

Abstract: A system and method for maintaining and updating data objects associated with mobile electronic devices is provided. In an embodiment, a data object manager engine receives data representing a first electronic device and a second electronic device. The data object manager engine is configured to update a data object associated with the second electronic device that links to a data object associated with the first electronic device. Usage metrics adjustments in one data object used to make usage metric adjustments in the second data object.

Abstract: A billing profile management system and method is provided. In an embodiment, a billing profile manager is configured to cooperate with an existing network and prepaid server. The billing profile manager is configured to modify the prepaid server and maintain a billing profile for each subscriber that is separate from the billing profile on the prepaid server and which can ultimately override the prepaid server. Additional billing functionality to an existing network and prepaid server is thereby provided.

Abstract: A routing system and method are provided which use a composite cost in identifying routes. This allows a simple way of identifying the best route taking multiple metrics into account for each link simultaneously. The system allows for the inclusion of pruning constraints, and allows for various objectives such as bin packing or load balancing to be achieved.

Abstract: A method for selecting two maximally disjoint shortest paths between a source node and destination node in a network is provided. The method comprises determining a first explicit route between the source and destination nodes by using an original link cost for each link in the network, transforming the network by introducing conditional link costs, determining a second explicit route between the source and destination nodes in the transformed network taking into account the conditional link costs, and determining the two maximally disjoint shortest paths between the source and destination nodes by coalescing the first and second explicit routes. Beneficially, the step of introducing conditional link costs comprises adding additional parameters to links in the network and determining the conditional link costs depending on the position of each link relative to the first explicit route.
