Patent number: 11284239Abstract: The invention relates to a node in a communications network for enabling communication with at least one wireless communication terminal served by the communications network. According to an embodiment, the node stores at least one current User Equipment (UE) context of the at least one communication terminal to be used by a first network entity of the plurality of network entities in the communications network; receives, from a second network entity of the plurality of network entities, a message intended for the first network entity; and delivers at least a part of the received message to the first network entity and at least a part of the stored at least one current UE context to be used by the first network entity.Type: GrantFiled: February 15, 2016Date of Patent: March 22, 2022Assignee: Telefonaktiebolaget LM Ericsson (publ)Inventors: Yong Yang, Gunnar Rydnell, Anders Fredén

Patent number: 8515465Abstract: The present invention relates to a solution for paging of idle user equipment and in particular for changing mode status from idle to connected in an efficient manner. This is provided in a method, nodes, and a system arranged to determine a suitable paging message related to a framework table indicating selection criteria entries for access point name, quality of service class indicator, IMSI number, and IMEI number and determining from the framework table a paging granularity set to be used in the paging request from a granularity table comprising entries for paging areas, number of paging retries, and time between retransmissions.Type: GrantFiled: June 8, 2010Date of Patent: August 20, 2013Assignee: Telefonaktiebolaget L M Ericsson (publ)Inventors: Lasse Olsson, Anders Freden, Klas Hjelmgren

Patent number: 8200739Abstract: A method in a server for controlling the distribution of messages from a plurality of clients among a plurality of processing means, including the steps of: establishing whether a message received on an interface board of the server is addressed using a normal identity specific for the client that sent the message and, if yes, then: using a first algorithm to map the normal identity to a load index in a first mapping means; and, mapping the load index to one of the plurality of processing means using a mapping table provided in the interface board. If the message is addressed using an internal identity generated in the server, rather than the normal identity specific for the client that sent the message, then: using a second algorithm to map the internal identity to a load index in a second mapping means; and, mapping the load index to one of the plurality of processing means using the mapping table provided in the interface board.Type: GrantFiled: June 23, 2005Date of Patent: June 12, 2012Assignee: Telefonaktiebolaget L M Ericsson (Publ)Inventors: Staffan Bonnier, Hans Ronneke, Anders Freden, Staffan Winell

Publication number: 20110138046Abstract: The present invention relates to an arrangement adapted to be provided in a server node (50) in a communication system, handling a large number of clients, comprising a number of interface boards (201, 202, 203) handling one or more protocols for communication with different nodes and a number of processing means (101, . . . ,106) adapted to serve a plurality of clients which may use a number of different types of identities when addressing the server node (500). It comprises load distribution control means adapted to handle clients using at least two different categories of addressing identities separately, and to distribute the clients to processing means (101, . . . ,106), and being adapted to provide a number of load index values (LI1LI36), exceeding the number of processing means, and load index mapping means mapping between load index values and processing means in a load index mapping table (30, 301, 302, 303, 3011-3016).Type: ApplicationFiled: June 23, 2005Publication date: June 9, 2011Inventors: Staffan Bonnier, Hans Ronneke, Anders Freden, Staffan Winell
