Apparatus and methods of controlling call establishment

摘要

Apparatus and methods of controlling call establishment are described. A user equipment (UE) may determine to establish a call. In an aspect, the UE may detect a Wireless Local Area Network (WLAN) access node and receive, from a Wireless Wide Area Network (WWAN) access node, WWAN load-related information. Based on UE call establishment rules and the WWAN load-related information, the UE may determine whether to establish the call on the WWAN access node or the WLAN access node. In another aspect, the UE may determine WLAN access node characteristics associated with a received signal from a WLAN access node. The UE may forward a call establishment request, including the WLAN access node characteristics to a WWAN access node. The UE may receive a redirection command to redirect the call establishment request to the WLAN access node.

1. A method of controlling call establishment, comprising:
determining, at a user equipment, to establish a new packet switched call when the user equipment is in an idle mode and camped on a Wireless Wide Area (WWAN) access node; detecting a Wireless Local Area Network (WLAN) access node; receiving, from the WWAN access node, WWAN load-related information; determining, based on user equipment call establishment rules and based on the WWAN load-related information, an access node on which to establish the new packet switched call, the access node being one of the WWAN access node or the WLAN access node; establishing the new packet switched call using the determined access node; and wherein the establishing the new packet switched call using the determined access node includes establishing the new packet switched call using the WLAN access node without setup of a radio bearer with the WWAN access node.
