摘要:
A messaging system can initiate a communication with one or more users through via cell phone text messages, for example using the short message service protocol. These systems often need a way to correlate user responses with system requests or queries. This problem can present challenges because the email mailbox metaphor used by cell phone user interfaces generally allows users to reply to any previously sent messages, but no message context is automatically supplied. A system that may send multiple messages to a user needs a mechanism by which the system can correlate a user-sent response to one of potentially many system-sent requests or queries. Context correlation to resolve ambiguities can be based on one or more of a dialog-based solution, a token-based solution and a keyword-based solution.

A method implemented in a network component, the method comprising receiving a presence information message from a presence server in a ring of a plurality of presence servers, removing content in the presence information message that is previously originated by the network component and previously sent on the ring, copying the presence information message locally for subsequent processing, appending to the presence information message buffered presence information from a local client coupled to the network component, and forwarding the presence information message to a second presence server in the ring.

A method for transferring a data stream between devices on a network is initiated by one of the devices. The devices on the network include a first device requesting the transfer and a second device currently receiving the data stream via the network. The method steps include a first device determining a proximity to a second device. The method steps also include the first device initiating a command to terminate a data stream received by the second device via a network when the proximity is below a threshold; and the first device initiating a command to transfer the data stream via the network so that the data stream is received by the first device.

In a distributed system, such as a PBX (FIG. 1), which uses a database for its operation, a master copy (22) of the database having a first format is stored at a central node (10) and cache copies (32) of database portions (24) but having a different format are stored at peripheral nodes (11-12). A change to the database is made to the master copy, is recorded in a change table (26) corresponding to the affected database portion, and is sent to affected peripheral nodes. At initialization, a boot copy (25) is made of each database portion by translating the database portion from the master database format to the cache copy format. Periodically thereafter, each boot copy is replaced with a new boot copy that reflects changes presently recorded in the corresponding change table. When the new boot copy is generated, the present change table contents are erased. When a peripheral node calls for a new cache copy (e.g., upon reboot), it is sent the corresponding boot copy and any changes presently recorded in the corresponding change table.

Systems and methods that enable migration for state of an application, from a primary machine to a backup machine in platform virtualization systems. The migration employs a hybrid approach, wherein both a hypervisor, and an application itself determine states that are to migrate from the primary machine to the backup machine. Based on a direct communication between the application and the hypervisor—without assistance of local operating system—the hypervisor arranges for migration of the required states over to the backup virtual machine.

A system for optimizing server response time to polling for new e-mail messages by a client. A cache of memory storing information about a user for responding to polling queries is maintained by the server. When a polling session is established, the client transmits a query to the server. The server receives the query and reads the cache to retrieve the user information that includes the response to the query. The response read from the cache is then transmitted to the client.

摘要:
Called party information is provided during survivable processor mode operation of a branch included in a distributed private branch exchange communication system for support of features that require information identifying the called party. More particularly, a coverage path for use during survivable processor operation is enabled that establishes contact with an extension or coverage point over the public switched telephony network such that operation of system appears normal to a caller. Furthermore, for a given coverage point, the same coverage path can be used for a number of extensions, reducing administrative burden.
