TL;DR: In this article, it is determined whether a location of a mobile device is within a coverage region of a first information service and if not, the location of the mobile device can be switched to another information service when the original information service fails.
Abstract: It is determined whether a location of a mobile device is within a coverage region of a first information service. Communications for the first information service are redirected to a second information service when the location of the mobile device is not within a coverage region of the first information service. The second information service generally has a coverage region encompassing the location of the mobile device. Communications between a mobile device and a first information service are redirected to another information service when properties of the new information service are determined to meet predetermined criteria set by a user of the mobile device, by an application, or both. In yet another aspect of the invention, Replacement of information services can be “aggressive” or “non-aggressive.” Communications between a mobile device and an original information service are redirected to another information service when the original information service fails.

19 May 1999TL;DR: In this article, the authors present a system and method for providing dynamic references between services in a computer system which allows a first service (e.g., an application program running on a client computer in a local environment) to gain reference to a second service without requiring knowledge of how to find the service or a particular version of the service on a distributed computer network.
Abstract: A system and method for providing dynamic references between services in a computer system which allows a first service (e.g. an application program running on a client computer in a local environment) to gain reference to a second service (e.g. a service running on a server computer in a distributed environment) without requiring knowledge of how to find the service or a particular version of the service on a distributed computer network. In a particular embodiment disclosed, when a getService method is called, a reference back to an instance of the service is returned and an implementation of a service connector interface encapsulates the logic necessary to lookup an instance of a specific service and return a reference to that service. In this regard, developers of a service may write, or program, a module that adheres to a service connector interface. Users of a service specify that the service connector provided by the service can be used to dynamically gain a reference to the service in their application. Additional methods can be added to the service connectors to support retrieval of references to specific versions or instances of a service.

12 Jul 2012TL;DR: An optimized service mediation framework may use customized tokens for reducing cost and latencies per transaction as discussed by the authors, in particular, a token service and an integration service may function together to generate customized tokens, for use by network components within a transaction pathway.
Abstract: An optimized service mediation framework may use customized tokens for reducing cost and latencies per transaction. In particular, a token service and an integration service may function together to generate customized tokens for use by network components within a transaction pathway. Each network component may access information with the token for a predetermined time period and/or for a predetermined number of service calls for service processing tasks related to mapping, security, governing, bridging, transforming, orchestrating, generating events, managing workloads, routing, validating, managing cache, encrypting, queuing and staging, commodity services, transaction management, and quality of service (QoS)/resiliency, among other things.

12 Jul 2011TL;DR: In this article, the authors propose a service mediation framework that allows each component within a computer network to perform common service processing tasks driven by standardized service policies stored within a centralized repository.
Abstract: A service mediation framework may allow each component within a computer network to perform common service processing tasks driven by standardized service policies stored within a centralized repository. In particular, an enhanced service domain name system (DNS) server, an enhanced service router, and/or an enhanced service gateway within the network may each access relevant service policies stored within an enhanced service repository to implement tasks such as security, content-based routing, logging, message format translation, and protocol bridging for each service request processed by the network. In addition, each network component may communicate through standardized formats, such as Extensible Markup Language (XML), to realize the end-to-end network solution.
