Roaming support for software defined networking architecture in mobile network

摘要

A software defined networking controller can be provided to manage sharing of information relating to roaming requests for mobile devices that are roaming on visited networks. The software defined networking controller can be a sub-instance of a main software defined networking controller that manages traffic within the home network, and the software defined networking controller can sit at the edge of the home network and control edge routing elements. The edge software defined networking controller may communicate with roaming partner's edge software defined networking controller and/or with the roaming interconnect operator's software defined networking controller to exchange roaming related information.

主权项

1. A first software defined networking controller, comprising:
a processor; and a memory that stores executable instructions that, when executed by the processor, facilitate performance of operations, comprising:
receiving a service profile request from a policy and rules charging function network element of a visited mobile network, wherein the service profile request is associated with a mobile device that is roaming on the visited mobile network, and wherein a first protocol associated with the policy and rules charging function network element is different from a second protocol associated with a second software defined networking controller of a home mobile network;translating the first protocol based on the second protocol resulting in an updated service profile request;forwarding the updated service profile request to the second software defined networking controller of the home mobile network;retrieving service profile data representative of a service profile of the mobile device from the second software defined networking controller that received the service profile data from a policy data store of the home mobile network of the mobile device; andinitiating transmission of the service profile data about the mobile device to the policy and rules charging function network element.
