1. A method for processing a request from a visitor location register (VLR) for a wireless device to utilize a visited network served by the visitor location register, the method comprising:
- receiving, by a home location register (HLR) of the home network to which the wireless device belongs, along any one of a plurality of communications paths, a message from the visitor location register to request that the wireless device use the visited network; and
transmitting, by the home location register, an authorization message responsive to the request message from the visitor location register, wherein the authorization message from the home location register is transmitted along a predetermined path of the plurality of communications paths, and wherein the predetermined path is selected based on the predetermined path routing into a steering of roaming (SOR) platform, the SOR platform being provided by an entity other than the operator of the HLR.

21. A method for processing a request from a visitor location register (VLR) for a wireless device to utilize a visited network served by the visitor location register, the method comprising:
-
receiving, by a home location register (HLR) of the home network to which the wireless device belongs, along any one of a plurality of communications paths, a message from the visitor location register to request that the wireless device use the visited network; and transmitting, by the home location register, an authorization message responsive to the request message from the visitor location register, wherein the authorization message from the home location register is transmitted along a predetermined path of the plurality of communications paths, and wherein the predetermined path is selected based on the predetermined path routing into a steering of roaming (SOR) platform; and receiving, by the home location register and subsequent to the transmitting of the authorization message, an abort message designated a TCAP abort from the SOR platform such that the abort message serves to inform the HLR that a registration attempt has been aborted.
