A system and method for verifying an application's authorization to receive position information comprising receiving a request for position information from the application, determining that the application has not yet been approved to receive the requested position information, sending a challenge key to the device on which the application is running, sending an application key to the application, sending a challenge string to the application, receiving an encrypted hash of the challenge key, application key and challenge string from the application, verifying that the encrypted hash is an expected value, and sending positioning server information to the application.

Improved techniques for reducing delays faced by users of mobile devices due to unavailability of wireless networks are disclosed. The techniques facilitate the reduction of delays faced by users of mobile devices during unavailability of wireless networks. A first technique allows mobile devices to communicate with remote servers using asynchronous communications, namely asynchronous requests. Such asynchronous communications allow the processing at a mobile device to continue while the asynchronous request is processed in the background. A second technique pertains to the use of content channels with mobile devices. The content channels are stored and retained in cache memory so that their resources are guaranteed to be locally available, regardless of availability of wireless networks. A third technique pertains to improved list processing within mobile devices such that lists can be manipulated without server interaction. These various techniques can be used separately or in combination.

The Web Services Development Kit (WSDK) comprises a set of build-time tools and run-time components designed to support the development of web services and the interface to those services. WSDK provides a framework for the development of web services that isolates developers from the implementation details of the markup and transport layers, by separating the logical aspects of the service development from the physical aspects. A nullcallnull generated by a client contains a batch of operations to be executed in the context of a single request/reply message exchange. A markup library translates logical structure to a specific markup language. Additional markup languages are supported by adding additional modules to the markup library.

Improved techniques for presentation of information on devices operating in communication systems are disclosed. An inter-device linking system can be used to inter-link various devices operating in the communication system. The inter-device linking system can detect when information cannot be presented on a first device. Moreover, the inter-device linking system can facilitate presentation of information on a second device. This allows the user to conveniently inter-link various communication devices. As a result, the user can conveniently schedule a device to present information while working on another device.

A group of wireless device users are notified of an event. A location data determination algorithm is provided to a wireless device, where the algorithm determines a frequency at which the device interacts with network elements to determine its location. The location data is stored in a notification server and used to identify a user at a specific location. When a governmental or commercial entity wishes to issue a notification, a message is provided to those users whose location is identified as being in an area defined by the entity.

In one embodiment a method comprises: at an access network, receiving a first request from a request source for an advertisement; requesting request source information related to the request source from an access network knowledge base using identification data of the request source; generating a second request for an advertisement in response to the request source information; and sending the second request to an ad server to obtain a targeted advertisement for the request source based on the request source information.

Embodiments of a method and system for enforcing a traffic policy at a Policy Enforcement Point (PEP) that controls the flow of traffic in a wireless communications network are described. In one embodiment, a method involves learning the topology of the wireless communications network, defining a virtual PEP (VPEP) within the topology of the wireless communications network, the VPEP comprising a location component that is remote from the PEP, associating a traffic policy with the VPEP, associating a traffic flow with the VPEP if the traffic flow has a characteristic that corresponds to the location component of the VPEP, and enforcing, at the PEP, the traffic policy that is associated with the VPEP against the traffic flow.
摘要:
This invention concerns a process and a system for providing location information for a wireless unit in a wireless network to a location-based service provider, using a data network. In particular, the location information is provided to the location-based service provider without necessarily providing the identity of wireless unit, e.g., a subscriber's wireless identification number, to the service provider. In this regard, a subscriber's identification number may be hidden from the positioning service provider via a process in which an alias is used instead of the subscriber's normal identity. The subscriber's number may further be concealed from the service provider via a process wherein encrypted information is used instead of the subscriber's normal identity.
摘要:
A system and method for sending location-based messages to mobile communication devices utilizes communications between base stations and mobile switching devices of a mobile access network to calculate the latest locations of the mobile communication devices supported by the mobile access network. The calculated locations of the mobile communication devices are maintained as location data in at least one location database, as well as information about the mobile communication devices. The location data and the information about the mobile communication devices are used to send the location-based messages to the mobile communication devices located within a specified geographical area.
