Methods, systems, and computer readable media for utilizing a diameter proxy agent to communicate short message service (SMS) messages

摘要

A method for utilizing a Diameter proxy agent to communicate short message service (SMS) messages in a Diameter network includes receiving, from an SMS service center via a Diameter interface, a mobile subscriber location information request message directed to a home subscriber server (HSS), wherein mobile subscriber location information request message is associated with a recipient mobile subscriber. The method further includes querying a number portability database to determine whether the recipient mobile subscriber has been ported to a foreign network and forwarding the mobile subscriber location information request message toward a gateway associated with the foreign network In response to determining the recipient mobile subscriber has been ported to the foreign network. The method also includes, in response to determining the recipient mobile subscriber has not been ported to the foreign network, forwarding the request message to the HSS in the first network or the foreign network.

1. A method for utilizing a Diameter proxy agent to communicate short message service (SMS) messages in a Diameter network, the method comprising:
at a Diameter proxy agent located in a first network:
receiving, from an SMS service center via a Diameter interface, a mobile subscriber location information request message directed to a home subscriber server (HSS), wherein the mobile subscriber location information request message includes a mobile subscriber identifier associated with a recipient mobile subscriber, wherein the Diameter interface includes an S6c Diameter interface;querying a number portability database to match the mobile subscriber identifier associated with the recipient mobile subscriber to an entry in the number portability database in order to determine whether the recipient mobile subscriber has been ported to a foreign network or ported into the first network, wherein the number portability database includes a location routing number (LRN) of a network element that is serving the recipient mobile subscriber in the foreign network if the recipient mobile subscriber has been ported to the foreign network;in response to determining the recipient mobile subscriber has been ported to the foreign network or is owned by the foreign network, forwarding the mobile subscriber location information request message to the foreign network using the LRN obtained from the number portability database; andin response to determining the recipient mobile subscriber has not been ported to the foreign network or has been ported into the first network, utilizing a subscriber location function in the Diameter proxy agent to determine an HSS in the first network that contains location information associated with the recipient mobile subscriber, and forwarding the request message to the HSS determined by the subscriber location function.
