Abstract:
1. A method of controlling a paging admission rate in a network node of a wireless communication network, wherein the network node receives a first number of paging messages for establishment of communication transactions within a paging area of the wireless communication network, the network node forwards a second number of paging messages as subset of the first number of paging messages to a paging area of the wireless communication network for subsequent broadcast thereof, and the paging admission rate to be controlled determines a ratio between the second number of paging messages and the first number of paging messages, and wherein the network node further includes at least one processor coupled to a non-transitory computer-readable storage medium storing computer-readable instructions, when executed by the at least one processor, is configured for: setting, using the at least one processor, a lower paging success rate limit; setting, using the at least one processor, a paging admission rate increase limit determined as a function of the paging admission rate; setting, using the at least one processor, an upper paging success rate limit wherein the upper paging success rate limit is larger than the lower paging success rate limit and the paging admission rate increase limit; calculating, using the at least one processor, a paging success rate as a ratio between a third number of paging messages being successfully broadcast in the paging area and the second number of paging messages; and increasing, using the at least one processor, the paging admission rate when the paging success rate is lower than the lower paging success rate limit but higher than the paging admission rate increase limit.
