Method for fast reinstallation of deployed devices

摘要

After a user device unsuccessfully attempts to establish upstream communication with a central network equipment downstream frequency to which it has tuned, an identifier corresponding to the tuned-to downstream frequency is removed from a cache of the user device. The frequency identifier stored in the cache typically corresponds to a frequency to which the user device has previously successfully tuned. The frequency identifier is removed from the cache after a predetermined attempt period, which may be determined by the number of attempts to establish communication that are made after previous unsuccessful attempts.

主权项

1. A computer-implemented method, comprising:
locking a user device at a new location to a frequency provided by central network equipment, the frequency being associated with a frequency identifier stored in a cache of the user device; transmitting a network access request message to the central network equipment; determining whether a response to the network access request message has been received from the central network equipment; and removing the frequency identifier from the cache if the response to the network access request message has not been received from the central network equipment at the new location.
