In one embodiment, a method includes identifying a plurality of network elements for reinitiation, wherein the network elements are operative to manage at least one child element; selecting a first network element from the plurality of network elements, transmitting a disable message to the first network element; determining whether the at least one child element has migrated to one or more alternate network elements; and conditionally transmitting a reinitiation message to the first network element.

A troubleshooting system. In particular implementations, a method includes collecting, from a first wireless network element, PEM state associated with a wireless client having a connection problem, and collecting log data associated with the wireless client from the first wireless network elements and one or more other wireless network elements. The method further includes correlating the PEM state and log data based on a network security protocol employed by the wireless client, where the network security protocol corresponds to an expected sequence of events. The correlating includes correlating events and messages collected based on the expected sequence of events, and comparing the correlated sequence of events to a data store of diagnostic information to identify one or more possible causes of the connection problem.

Coordinated reboot mechanism reducing service disruption in network environments

A method wherein an autonomous system that must move off of the current DCCH channel: determines a new DCCH channel; transmits on the current DCCH channel a new PSP/POF list in which the new DCCH replaces the current DCCH, transmitting the new PSP/POF list for a time sufficient for mobile stations camped on the current DCCH to update their PSP/POF lists; and begins broadcasting on the new DCCH channel. Whereby a MS camped on the current DCCH: receives the new PSP/POF list; updates its internal tables; loses communications on the current DCCH; performs the Control Channel Reselection procedure; finds the new DCCH channel; and camps on it.
