Abstract: An access client hosted by a mobile computing device accesses carrier networks using wireless access points and uses an access point database to identify access points and carrier networks. The access client uses methods and tokens databases to access carrier networks. The access client updates the databases using an access server when coupled to a carrier network. The access client transmits user information to the carrier network, which uses the information to perform authenticate and generate session data. The carrier network transmits session data to the access server, which uses session data to generate billing information. The access client also collects network performance data for access points and carrier networks, and transmits network performance data to the access server. The access server aggregates network performance data from access clients to generate quality of service reports. The access client includes detection and evaluation features for selecting access points.

Abstract: A system and method is disclosed for accessing properties used to customize network documents to a user. In one aspect of the system and method, an application developer may obtain user properties that are stored on multiple storage mechanisms by using a single logical name, which is a user-friendly name of a data structure on one of the storage mechanisms. The user-friendly name makes it faster and easier for an application developer to create applications. The user-friendly name also frees the application developer from having to determine the location of the storage mechanisms on the network.
