Patent number: 9961596Abstract: A method for determining a capability of a user equipment. The user equipment is served by a non-shared network in a first place. The non-shared network is configured to transmit a message to the user equipment, the message including information on at least two PLMN identities. The user equipment is configured to deliver a response message from which it is determined if the response message includes information field reserved for at least one PLMN identity in the transmitted message. On a basis of an existence of the information field in the response message it can be determined that the user equipment supports network sharing. In other case it is determined that the user equipment is not supporting network sharing. A network node and a system implementing at least part of the method are also described.Type: GrantFiled: January 24, 2014Date of Patent: May 1, 2018Assignee: TELIA COMPANY ABInventors: Anders Dahlen, Ulf Nilsson

Patent number: 8165587Abstract: A cellular radio communications network includes a core network coupled to a radio access network (RAN) that has multiple RAN nodes for communication with mobile radio terminals. Each of the multiple RAN nodes serves one or more cells. At least one cell associated with a first RAN node is in a restricted or reserved access state in which access to the one cell is restricted for at least some mobile radio terminals. The first RAN node sends a message to a second RAN node to inform the second RAN node of that restricted access cell. The fact that the restricted status of the one cell has changed is detected. A global message tha is not related to a specific mobile terminal is generated that includes information that the restricted status of the one cell has changed. The first RAN node sends the global message to the second RAN node to inform the second RAN node of the change in the restricted status of the one cell.Type: GrantFiled: February 7, 2008Date of Patent: April 24, 2012Assignee: Telefonaktiebolaget LM Ericsson (publ)Inventors: Anders Dahlen, Mats Buchmayer, Martin Israelsson, Mattias Wahlqvist

Patent number: 7894338Abstract: In a method of sharing a Radio Access Network, RAN, in one or more areas by at least two operators the determination whether to grant admission or not of a User Equipment, UE, to the RAN is performed in an admission control algorithm. A Radio Network Controller, RNC, is reading Network Resource Identifier, NRI, information contained in an “Initial Direct Transfer” message sent by the UE when requesting a service, and the read NRI information is used in a service admission control to check a plurality of service admission parameters as a part of a set of admission control parameters to grant or reject the requested service depending on whether the operator associated with the NRI has invested in needed technology or not. A corresponding radio access network comprises admission control means to determine whether to grant admission of a User Equipment, UE, to the network, RAN, or not.Type: GrantFiled: December 21, 2005Date of Patent: February 22, 2011Assignee: Teliasonera ABInventors: Rickard Ljung, Anders Dahlen

Publication number: 20090117897Abstract: Methods and apparatuses for automatically determining neighbor cells are disclosed. Cell information is received. The received cell information is compared with a list of old neighbor cells. When a new cell is detected, a determination is made as to whether the detected new cell covers the same geographical area as any of the old neighbor cells. When the new cell covers the same geographical area as at least one of the cells of the list, the new cell is stored as a neighbor cell in the list. Cell information is received. The received cell information is compared with a list of old neighbor cells. New neighbors are detected based on the comparison. A determination is made as to whether there are cells in a same geographic area as the new neighbors. A determination is made as to whether there are new cells in a same geographic area as the old neighbor cells. The new neighbors, the cells in the same geographic area as the new neighbors, and the new cells are stored as neighbors in the list.Type: ApplicationFiled: October 30, 2008Publication date: May 7, 2009Inventors: Martin Israelsson, Mattias Wahlqvist, Mats Buchmayer, Anders Dahlen
