This invention provides a novel switch for use in a telecommunications network that is capable of interacting with a voice assisted services server, such as a voice activated dialing (VAD) server. The switch is configured to set-up a calling session between an originating terminal and the VAD server that creates a voice connection between the user at the originating terminal and the VAD server, the voice connection passing through the switch. The VAD server can then in response to a spoken utterance indicative of the party the user wishes to call, generate a transcription of the utterance and extract from a database the telephone number associated with this transcription. The VAD server then formulates a call session redirect message in which is embedded the telephone number of the party the user wishes to call. This call session redirect message is received by the switch and the command implemented such that the call session is redirected toward the desired location. After this procedure is completed, the connection between the switch and the VAD is released.

A signaling network routing node, such as a signaling system 7 (SS7) / Internet protocol (IP) gateway, is adapted to perform global title translation (GTT) or other processing on received signaling messages and route the signaling messages to a member of a load sharing group using a threshold-based weighted load sharing algorithm. In the event that one of the signaling destinations in the load sharing group becomes unavailable, signaling message traffic is redistributed evenly among the remaining available members of the load sharing group in a manner such that a maximum load sharing weight threshold value associated with each group member is not exceeded. If a load sharing group member becomes unavailable, and the resulting recalculated load sharing weights of the remaining available members sum to less than 100%, then load sharing weights for the group are normalized, and a maximum message rate capacity threshold associated with each group member is used to determine whether the discarding of messages is required.

A method for auditing databases containing records of varied record formats verifies records from a test database against records from a reference database. Records from the test database are converted to test tokens, and records from the reference database are converted to reference tokens. The tokens summarize select fields of data from the records. Thereafter, pattern recognition techniques are used to analyze the tokens to determine Whether the data in the test tokens matches to data in the reference tokens. When an erroneous test token is discovered, an update token is generated to correct a corresponding record in the test database. This method is particularly well suited for auditing enhanced 911 emergency telephone service selective router databases.

A method and system for changing the extent of data plane resources controlled by a control plane for a network connection which spans a contiguous set of nodes controlled by existing network control resources is disclosed. This is done in a non-disruptive manner. This typically involves two steps: i) Creating a new set of control plane resources for said network connection such that said data plane resources are shared with said existing network control resources; and ii) then terminating the existing network control resources such that said data plane resources are fully transferred to the new set of control plane resources without disrupting said network connection. The existing network control resources can be either a control plane resource or a non control plane resource. An example of a non control plane resource is network management software (e.g., an OSS (Operation Support System)), which forms part of the Management Plane. It should be noted that this does not need to be done for a complete end-to-end connection, but rather can be executed for the portion of the end-to-end connection which is to be controlled by the control plane.
