Abstract
A system and method for effectuating selective triggerless local number portability (TLNP) processing in a telecommunications network having a cellular network portion and a wireline network portion. When an IAM message is received at a signaling node from an MSC on a TLNP-enabled link set, a determination is made at an STP associated therewith whether the NPA-NXX of the received dialed number is marked as portable. If not, the TLNP processing is discontinued and the message as originally received is forwarded to the wireline network portion for further processing. Otherwise, another determination is made if the dialed number is a ported number. If it is determined that the dialed number is not a ported number, the IAM message is marked as dipped and forwarded to the wireline network portion based on the Destination Point Code (DPC) associated with the message. On the other hand, if the dialed number is a ported number, a further determination is made if the DPC of the message corresponds to a match in a DPC/LRN database table. If the DPC is not in the DPC/LRN database table, the TLNP processing is applied to the message before it is forwarded to the wireline portion based on the DPC identified in the message. If the DPC is in the DPC/LRN database table, it is yet further determined whether the LRN received from the database query corresponds to a match in the DPC/LRN database table. If the LRN is not in the DPC/LRN database table, the message is forwarded, again as originally received, to the wireline network portion. Otherwise, the TLNP processing is applied to the message before it is forwarded to the wireline portion.
