A communication network (,) includes a first server (,) and a second server, such as any of the servers (,), connected via a common network (,). First server (,) owns a record data (,) associated with at least one process running for serving a client device (,.) The second server keeps a copy of the record data. First server (,) performs a Hashing function over record data (,) to produce a first Hash value. The second server similarly performs the same or similar Hashing function over the copy of the record data to produce a second Hash value. First server (,) sends the first Hash value to the second server for comparison. If the first Hash value fails to match to the second Hash value, a latest copy of the record data (,) is sent from first server (,) to the second server upon request.

Method and apparatus in a communication network for updating and maintaining record data

A transmitting device (15) for communication over a multiplicity of networks having a communication manager (22) and a mobility manager (20). The mobility manager (20) includes a database (40) having a net table (42) of potential networks and a filter (38). The filter (38) generates a prioritized list of qualifying networks over which a data object is to be transferred. Also described is a method for sifting through and filtering the net table (42) of potential networks and their characteristics. A prioritized list of qualifying networks is generated wherein each qualifying network has a priority. A transmission request is generated based on a combination of the data object and the prioritized list of qualifying networks and is transmitted over the selected qualifying network (26), (28), or (30) having a highest priority.

Transmitting device with mobility manager and method of communicating

A profile is maintained, either in a central profile data base (106) or in a more distributed manner that includes local profile data bases (706). These profile data bases include preference information for particular users, which preference information is utilized by the system to direct various messages from various sources to various destinations for a particular user. By accessing the system through an appropriate input source (708), the user can provide temporary over-ride instructions that cause this preference information to be temporarily altered. When so altered, messages that would ordinarily be directed to a location in accordance with the original entries to the profile data base will be directed instead to a temporary destination (707) as identified by the user. This temporary destination can either be identified in particular at the time of entering the temporary over-ride instruction, or can be pre-identified in an over-ride plan (709). The over-ride instruction will be removed and the original conditions reset upon occurrence of a predetermined event. This predetermined event can be, for example, occurrence of a pre-established expiration time and/or reception of a reset instruction subsequent to reception of the temporary over-ride instruction.

Temporary message routing and destination selection

A method and apparatus for routing information within a communication system (100) is based upon evaluating various attributes (310) of the information to be routed. The methodology employs processing steps including, but not limited to receiving a message (300) having a key (304) and a first set of message attributes (310), each attribute having a value. Extracting the key (304) from the message to index a data base (400) in order to retrieve records (410) having the key and containing a representation of a logic function (406) that describes a second set of message attributes. The first set of attributes values are applied to the logic function (406) of the first retrieved record to determine whether the function is true or false. If true, that data base record is selected for use in routing the information. Otherwise, the first set of attribute values are applied to the logic functions of each indexed data base record (410) until a true condition is encountered. This methodology is employed with the selection of a destination device as well as the selection of a communication network.

Method and apparatus for routing information in a communication system

In a switched integrated wideband and narrowband multiservices digital network (FIG. 1), the network control complex (612) includes a program-controlled call processing arrangement (800) that comprises a point-to-point call processing portion (8001) for handling point-to-point calls and a proxy vendor call processing portion (8002) for handling calls to broadcast program service vendors. For quick response to 'channel change' requests from subscribers, the proxy vendor portion handles all calls within a single process (500). For ease of call control, the point-to-point portion handles each call via two processes (650, 660) one for each of the calling and called portions of each call. A message router (8000) receives messages from subscriber terminal equipment (400) requesting control functions for calls and routes them to the appropriate one of the proxy vendor and point-to-point processes. The message router also creates the point-to-point processes for new calls for which the processes are not yet in existence. Subscriber messages have two portions: a first portion requesting control functions for calls and a second portion identifying calls. Subscriber messages for both point-to-point and proxy vendor calls have identical first portions for requesting identical functions, thereby hiding the difference between the two call processing portions from subscribers. Only the second portions distinguish messages for point-to-point and proxy vendor calls. The called portions of proxy vendor call paths are pre-established. A resource management arrangement (803), which cooperates with call processing to establish call paths, comprises a point-to-point portion (8030) for establishing and controlling call paths for calling and called portions of point-to-point calls, and a proxy vendor portion (8031) for establishing and controlling calling portions of proxy vendor calls.

Communication system control arrangement

In a multiservices digital network (FIG. 1), comprising separate narrowband switch (607) and wideband switches (505, 606), the network control complex (612) includes a program-controlled call processing arrangement (800) that is program-independent of a resource management arrangement (803) and of the physical network. The call processing arrangement views the network as comprising logical channels and logical call paths interconnecting logical channels. It does not distinguish between narrowband and wideband communications; it responds to subscriber (102) messages requesting subscriber functions for both narrowband and wideband communications by directing the resource management arrangement to establish and dismantle logical call paths and to create and destroy logical and physical connections between the logical channels and the logical call paths. The resource management arrangement distinguishes between narrowband and wideband communications; it responds to the directions by allocating and deallocating either narrowband or wideband network physical resources, as appropriate, for physical channels and physical call paths corresponding to the logical channels and the logical call paths, and directs either wideband switch controllers (507, 610) or narrowband switch controller (611), as appropriate, in creating and destroying the requested logical and physical connections between the channel and call path resources. The call processing arrangement is thus made independent of network physical resources, while the resource management arrangement is made independent of subscriber functions.
