Abstract

In some embodiments, an access terminal is configured to select a first set of system resources, and communicate a message to acquire access to the first set of system resources, wherein the message conceals that the access terminal is capable of communication with a second set of system resources. In one embodiment, the first set of system resources includes circuit-switched system resources, the second set of system resources includes packet-switched system resources, and an access terminal conceals from the network that it is operable using the packet-switched system resources in order to acquire and / or maintain connected mode access to the circuit- switched system resources. Such embodiments allow an access terminal to use circuit- switched system resources even if the network does not support CS fallback or has refused a CS fallback request.

Description

[0001] Claiming Priority Based on 35 U.S.C. §119 [0002] This patent application claims priority to US Provisional Application No. 61 / 170,997, filed April 20, 2009, entitled "METHOD AND APPARATUS TO ENABLE SELECTION OF RADIO ACCESS TECHNOLOGY SUPPORTING PREFERRED SERVICE IN CONNECTED MODE." The aforementioned application is hereby expressly incorporated by reference. technical field [0003] The present application relates to wireless communication, and in particular to a system, method and device for realizing wireless network resource management. Background technique [0004] Wireless communication systems using packet switching technology are widely deployed to provide various types of communication, such as voice, data, multimedia services, and so on. The increasing demand for high-rate wireless data services continues to drive the shift to packet-switched technologies. However, as the demand for high-rate wireless data services grows, there is the challenge of provid...
