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.
