Tiered subscriber service with advanced header compression methods in a VOIP system

摘要

One or more computer readable media, methods and systems that allow phone calls involving a mobile telephone to be to be conducted using VOIP technology with header compression of the voice packets and dynamically adjustable tiered subscriber service. A dynamic, tiered-subscriber service allows the bandwidth allotted to users subscribing to different levels of service to be adjusted between sessions to accommodate changing network conditions. Header compression involves compressing the voice packet header into a reduced number of bites. Embodiments of the present invention enable simultaneous header compression and dynamic tiered-subscriber service through a new call flow set up that includes a new policy. The new policy is given preference over the other installed policies and includes new attribute value pairs that enables both header compression and dynamic bandwidth adjustments.

主权项

1. One or more non-transitory computer-readable media with computer-executable instructions embodied thereon that when executed performs a method of setting up a wireless telephone call utilizing VOIP technology with dynamically adjustable bandwidth allocation based on tiered subscriber service, the method comprising:
during setup of the wireless telephone call including a mobile-communication device as at least one endpoint of the wireless telephone call, installing, on a gateway, a header compression policy governing a flow of voice packets between the mobile-communication device and a radio access network, the header compression policy including:
(1) a first attribute-value pair that defines header compression parameters for the voice packets, and(2) a second attribute-value pair that instructs the gateway to allocate bandwidth for the wireless telephone call according to a subscriber service level associated with the mobile-communication device; installing a static policy on the gateway; installing a signaling policy on the gateway; and installing a bearer policy on the gateway, wherein the header compression policy is installed after the bearer policy, the signaling policy, and the static policy are installed on the gateway, wherein the header compression policy is installed after a media flow is set up, wherein the bearer policy and the signaling policy are installed in conjunction with a signaling flow setup, and wherein the static policy is installed in conjunction with a main connection set up.
