Abstract: The disclosure relates a technique that allows one to identify communication sessions which are mistakenly detected as normally terminated from the network perspective. The first time period is used to monitor normal session releases initiated by a core network (CN) in respect of communication sessions for UEs. The second time period is used to check whether a Radio Link Failure (RLF) timer is already triggered at the time instant when the normal session release(s) is(are) detected by the RAN node within the first time period. If the RLF timer is already triggered, the number of the communication session(s) to be normally released based on the normal session release(s) from the CN is counted and reported to a network management system when the first time period expires. In response, the network management system properly optimizes RAN or other network parameters such that a call drop rate is improved.

Abstract: Example embodiments of the invention as disclosed herein provide at least a method an apparatus to perform communicating, by a network device of a communication network, at least one data burst comprising at least one data block towards an access node of the communication network, wherein the communicating includes: determining, a buffer status of a buffer for communicating the at least one data block with the access node; based on the determining, setting at least one value of at least one timer for each data block of the at least one data block, wherein said at least one timer is identifying at least one given time the buffer is reserved for each data block of said at least one data block; and based on at least said at least one given time, communicating the at least one data burst with the access node, wherein the at least one value of said at least one timer is determined based on a volume of each data block.
