US Classification:

714 4, 714 15

Abstract:

A system for managing failover in a server cluster. In response to detecting a failed server, subscription message processing of a failover server is stopped. A subscription queue of the failed server is opened. A marker message is published to all subscribers of a particular messaging topic. The marker message includes an identification of the failover server managing the subscription queue of the failed server. Messages within the subscription queue of the failed server are processed. In response to determining that a message in the subscription queue of the failed server is the marker message, the subscription queue of the failed server is closed. Then, the failover server resumes processing of its original subscription queue looking for the marker message, while processing yet unseen messages from the queue. Once the marker message is found in the original subscription queue, normal operation is resumed.

Abstract:

Systems, methods and computer program products for automatic network-based persistent XML storage and management. Exemplary embodiments include a method including loading an XDM widget having internal XML, sending an XCAP GET request via an XCAP URI parameter, retrieving an existing XML document at a location associated with the XCAP URI parameter, invoking an initializer callback function via the XDM widget to populate the internal XML with default values associated with an etag, wherein the etag is null, sending an XCAP PUT request via the XCAP URI to store the existing XML document, executing etag header scenarios, providing XML management functions to automatically publish changes to the server, and trigger a timer function to poll for updates from the server and display the resulting updates to the user's screen via a render callback function.

International Classification:

H04L 12/28

US Classification:

370351

Abstract:

The present invention discloses a solution that uses presence proxies to handle local presence information while using a presence server to handle extra-local presence information. In the invention, a computing system can include multiple presence user agents (PUAs), multiple watchers, multiple presence proxies, and a presence server. The PUAs can be are grouped into two or more sub-networks. The watchers can also be grouped by sub-network. The PUAs and the watchers can each be associated with a presentity. A presence proxy can be associated with each of the sub-networks. Exclusively local presence services for each sub-network ears be handled by the associated presence proxy. The presence proxy can route presence information for other presence services (those not exclusively local) to and from the presence server.

US Classification:

709230

Abstract:

The present invention discloses a method and a system for using presence proxies to group presence notifications. In the invention, a presence server can accept, manage, and distribute presence information. Multiple watchers can subscribe to the presence information managed by the presence server. A presence proxy can receive or intercept subscription requests from the watchers, can group these subscription requests, can establish a single subscription between the presence proxy and the presence server for each group of subscription request, can receive notifications form the presence server associated with the single subscription, and can convey received notifications to each of the watchers in a group associated with the single subscription responsive to receiving a corresponding notification from the presence server.

International Classification:

G06F 15/16

US Classification:

709203

Abstract:

A cache server receives a request from a client that includes a requesting entity tag. In turn, the cache server extracts a starting identifier and an ending identifier from the requesting entity tag. The starting identifier is associated with a starting entry and the ending identifier is associated with an ending entry. Next, the cache server determines whether a subsequent entity tag exists that includes a subsequent starting identifier that matches the requesting entity tag's ending identifier. When the cache server identifies a subsequent entity tag, the cache server sends the subsequent entity tag and one or more update entries corresponding to the subsequent entity tag to the client.

International Classification:

G06N 5/02

US Classification:

706 47

Abstract:

A rules engine can be initialized as part of an object grid, wherein the rules engine is executable code executing using computer resources. The rules engine updates a business mapper. The rules engine receives a business rule definition to form a business rule. The rules engine determines business terms are present in the business rule. The rules engine converts the business terms to technical terms based on the business mapper, responsive to a determination that business terms are present. The rules engine determines that the business rule comprises a temporal rule. The rules engine receives rule criteria, wherein the rule criteria is at least one selected from the group consisting of frequency, delay and timing dependency, responsive to the determination that the business rule is a temporal rule. The rules engine stores the business rule to the rules engine. The rules engine publishes the business rule to a publish-subscribe topic.

International Classification:

H04W 4/00

US Classification:

370259

Abstract:

A method for application-specific chargeback of content cached at a wireless tower of a RAN includes receiving a request for content from an end user device in a base station of a RAN and routing the request to an application in a packet switched data communications network from the base station by way of a CN. Content from the application can be received in the base station within a response to the request, the response can be cached in a local cache of the base station in connection with the application and the response can be forwarded to the end user device. Subsequently, in response to a new request for the content received in the base station, the content can be served in a response from the local cache. Further, an identity of the application can be transmitted to a remote charging service external to the base station but within the RAN for charging the application in consequence of having served the content from the local cache of the base station.

US Classification:

370328

Abstract:

Embodiments of the invention provide a method, system and computer program product for content caching with remote filtering services in a radio access network (RAN). In an embodiment of the invention, a method for content caching with remote filtering services in a RAN can include receiving a response to a request from an end user device wirelessly coupled to a base station of the RAN, marking the response as uncacheable, and routing the response to the base station over a data communications network. In one aspect of the embodiment, the response can be received in an RNC of the RAN. Of note, the process of marking the response as uncacheable can depend upon the evaluation of a policy with respect to the response. Finally, in another aspect of the embodiment, marking the response as uncacheable, can include annotating a hypertext transfer protocol (HTTP) header of the response to indicate that the response is not to be cached in the base station.
