摘要： Methods and systems for providing fast handoff in WLAN-like communications system construct a caching candidate set based upon a weighted handoff tendency coefficient. The weighted handoff tendency coefficient is based upon the handoff matrix and the weighting factor. The handoff matrix is an adaptive two-dimensional array that provides a list of nearby access points relative to a mobile station and the weighting factor is a value that prioritizes the nearby access points based upon a signal quality indication. A home access point, once it is triggered to initialize proactive caching, provides the caching candidate set with registration data of the mobile station before a transfer of a connection between the home access point and one of the access points on the caching candidate set.

摘要： Prioritized random access methods are proposed. According to an embodiment, random access attempts are classified into the priority levels according to delay requirements, and adedicated random access opportunities are reserved for different priority levels. A congestion detecting mechanism is introduced for such dedicated ranging (random access) opportunities. When congestion is detected by the base station, parameters or configurations of random access can be dynamically or temporarily modified through random access response message. Furthermore, a prioritized contention resolution is introduced to guarantee a high priority access is processed earlier than a low priority access. According to another embodiment, another prioritized contention resolution is introduced to reduce the impact of random access of a low priority M2M device upon H2H traffic.
