Call establishment and maintenance in a wireless network
First Claim
1. An apparatus, comprising:
- at least one processor configured to detect one or more access points in a wireless local area network (WLAN), to determine whether any detected access point is suitable for receiving service, to perform service registration with a suitable access point in the WLAN, wherein the service registration is for a first set of services depending on performance of the suitable access point and Quality of Service (QoS) requirements of the first set of services, to establish a communication call that is supported by the first set of services associated with the service registration, to determine either that (i) the performance of the suitable access point has changed so as to be different, or (ii) a handoff to a different access point with different performance than the suitable access point has occurred, to modify the service registration to a second set of services based on the performance difference determination, and to transition, in response to the modification, from supporting the communication call using the first set of services to the second set of services, wherein the first and second sets of services include different tiers of QoS support for supporting the communication call; and
a memory coupled to the at least one processor.

Abstract
Techniques to configure quality of service (QoS) and utilize radio resources for a call in a WLAN are described. In an aspect, a station ensures that an access point in the WLAN is suitable for receiving service prior to performing registration to receive services via the WLAN. In another aspect, the station first requests for radio resources for traffic flows, then requests for radio resources for signaling flows, and sends signaling as best effort traffic if radio resources are not granted for the signaling flows. In yet another aspect, the station aggregates QoS for multiple applications and requests for radio resources based on the aggregated QoS. In yet another aspect, the station releases extra radio resources corresponding to the difference between the QoS granted by the WLAN and the QoS proposed by a remote terminal for the call. In yet another aspect, the station requests for the same QoS or lower from a new access point during handoff.

8. A method, comprising:
-
detecting one or more access points in a wireless local area network (WLAN); determining whether any detected access point in the WLAN is suitable for receiving service; performing service registration with a suitable access point, wherein the service registration is for a first set of services depending on performance of the suitable access point and Quality of Service (QoS) requirements of the first set of services; establishing a communication call that is supported by the first set of services associated with the service registration; determining either that (i) the performance of the suitable access point has changed so as to be different, or (ii) a handoff to a different access point with different performance than the suitable access point has occurred; modifying the service registration to a second set of services based on the performance difference determination; and transitioning, in response to the modifying, from supporting the communication call using the first set of services to the second set of services, wherein the first and second sets of services include different tiers of QoS support for supporting the communication call. - View Dependent Claims (9, 10)

11. An apparatus, comprising:
-
means for detecting one or more access points in a wireless local area network (WLAN); means for determining whether any detected access point is suitable for receiving service; means for performing service registration with a suitable access point in the WLAN, wherein the service registration is for a first set of services depending on performance of the suitable access point and Quality of Service (QoS) requirements of the first set of services; means for establishing a communication call that is supported by the first set of services associated with the service registration; means for determining either that (i) the performance of the suitable access point has changed so as to be different, or (ii) a handoff to a different access point with different performance than the suitable access point has occurred; means for modifying the service registration to a second set of services based on the performance difference determination; and means for transitioning, in response to the modification, from supporting the communication call using the first set of services to the second set of services, wherein the first and second sets of services include different tiers of QoS support for supporting the communication call. - View Dependent Claims (12, 13)
