Abstract

In one embodiment of the invention, a number of transport protocol streams are established between a signaling session border controller (S-SBC) and a data session border controller (D-SBC). A subset of the number of transport protocol streams are dedicated for carrying messages for emergency calls. Upon receiving an emergency call, the S-SBC transmits an add request message to the D-SBC over one of the streams dedicated for carrying messages for emergency calls. Upon receiving the message over one of the streams dedicated for carrying messages for emergency calls, the D-SBC processes the message with high priority handling.
