Patent number: 11968618Abstract: The invention relates to methods and device for detecting when a mobile terminal is in a state where it is incapable of replying to a message. In a first aspect of the present invention, it is provided a method of detecting, at a mobility node in a communications network, a state where a mobile terminal is incapable of replying to a message. The method comprises receiving the message from a gateway node, and determining whether the mobile terminal is incapable of replying to the message. Further, the method comprises sending a response to the gateway node indicating that the mobile terminal is not yet capable to reply to the message.Type: GrantFiled: September 27, 2013Date of Patent: April 23, 2024Assignee: Telefonaktiebolaget L M Ericsson (publ)Inventors: Yong Yang, Qian Chen, Peter Hedman, Tony Olsson

Patent number: 11696358Abstract: The embodiments herein relate to a method performed by a gateway. The gateway detects that a procedure for activating or deactivating a bearer has been initiated. The gateway receives a first modify bearer or modify access bearers request message for the same PDN connection and UE as the bearer activation or deactivation procedure is intended for. The gateway detects a bearer mismatch between a first set of bearers and a second set of bearers known by the gateway and associated with said same PDN connection and UE. The gateway accepts, during a time interval, the received modify bearer or modify access bearers request message even though the bearer mismatch has been detected.Type: GrantFiled: July 16, 2021Date of Patent: July 4, 2023Assignee: TELEFONAKTIEBOLAGET LM ERICSSON (PUBL)Inventors: Tony Olsson, Patrik Hermansson, Yong Yang

Patent number: 10652946Abstract: The embodiments herein relate to a method performed by a gateway (108, 110, 1308, 1310). The gateway (108, 110, 1308, 1310) detects that a procedure for activating or deactivating a bearer has been initiated. The gateway (108, 110, 1308, 1310) receives a first modify bearer or modify access bearers request message for the same PDN connection and UE (101) as the bearer activation or deactivation procedure is intended for. The gateway (108, 110, 1308, 1310) detects a bearer mismatch between a first set of bearers and a second set of bearers known by the gateway (108, 110, 1308, 1310) and associated with said same PDN connection and UE (101). The gateway (108, 110, 1308, 1310) accepts, during a time interval, the received modify bearer or modify access bearers request message even though the bearer mismatch has been detected.Type: GrantFiled: March 7, 2016Date of Patent: May 12, 2020Assignee: TELEFONAKTIEBOLAGET LM ERICSSON (PUBL)Inventors: Tony Olsson, Patrik Hermansson, Yong Yang
