Abstract: A method and system for providing improved wireless number portability. This invention allows the mobile switching center (MSC) to use a separate database to store the number portability information gathered earlier through sending NPreq messages to the number portability database (NPDB) and various strategies for refreshing or updating the internal database. The invention enables the MSC to use the separate database to check whether a portable number is ported and what the associated location routing number (LRN) if it is ported, so that the MSC does not need to send NPreq messages to the NPDB many times for the same ported number. This invention may apply to any number of switching systems, including CDMA, GSM and UMTS mobile switching systems.

Abstract: Methods, systems, and computer program products for routing query messages associated with prepaid subscribers in a number portability environment are disclosed. One method may include sending a registration message to an HLR. At the HLR, the ID or address of an STP is inserted as the prepaid SCP ID in a registration response message. The registration response message is sent to the MSC/VLR that originated the registration message. This action forces the VLR to send prepaid query messages to the STP, rather than to the prepaid SCP. When the STP receives a query message relating to call originating from the prepaid subscriber, the STP performs a number portability database lookup and determines the routing number corresponding to the called subscriber and the prepaid SCP corresponding to the calling subscriber. The STP then routes the query message to the appropriate prepaid SCP.

Abstract: Network resources for a call between a calling party and a called party are allocated. The network resources for the call are reserved based on a reservation request. In particular, the network resources for the call are reserved based on a reservation request. Prior to the reservation request being made, one or more operational parameters for the call are established by a gate controller and sent to a network edge device or other routing entity associated with one of the parties. An identifier, illustratively a so-called gate identification, is sent to that party. Thereafter the routing entity receives the identifier from the associated party in, for example, the aforementioned resource reservation request. The routing entity is able to use the identifier to determine the one or more parameters established for the call and to thereupon cause the call to be established—including the reserving of resources—in a way that is consistent with the one or more parameters.
