Patent number: 9241280Abstract: A method in a first radio network node for testing a transmission parameter value in a wireless communication system is provided. The first radio network node is configured to, during operational mode thereof, perform transmissions using available resources divided in to resource blocks. The first radio network node allocates a test resource block, for test purposes, among the available resources. The first radio network node defines for the test resource block, a test value for the transmission parameter. The test value differs from the nominal value. The first radio network node performs, during operational mode, a test transmission using the resource block. During the test transmission, the transmission parameter is set to the test value. The test transmission is configured to form the basis for an evaluation of the test value.Type: GrantFiled: April 29, 2011Date of Patent: January 19, 2016Assignee: Telefonaktiebolaget L M Ericsson (Publ)Inventors: Harald Kallin, Birgitta Olin

Patent number: 9220039Abstract: In one of its aspects the technology concerns a method of operating a telecommunications system comprising a serving radio base station and a candidate radio base station. The serving radio base station comprises a radio base station to which a wireless mobile station provides measurement reports. The serving radio base station and the candidate radio base station are different with respect to at least one of frequency and radio access technology. The method comprises the serving radio base station allowing the mobile station to obtain information broadcasted by the candidate radio base station. The information is either information for locating Cell Global Identity (CGI) of the candidate radio base station or the Cell Global Identity (CGI) itself of the radio base station. The mobile station obtains the information from the candidate radio base station during at least one reading gap.Type: GrantFiled: October 10, 2013Date of Patent: December 22, 2015Assignee: Telefonaktiebolaget L M Ericsson (publ)Inventors: Mehdi Amirijoo, Pal Frenger, Fredrik Gunnarsson, Harald Kallin, Johan Moe, Kristina Zetterberg

Publication number: 20150334566Abstract: There is provided a method of authenticating a public land mobile network (PLMN) to a mobile station (MS). The PLMN provides a circuit switched access network to the MS, and the MS and a trusted service, TS, have established a security context. The initiation of a voice call or initiation of sending or receiving of a pushed message by the MS (S10.1) is detected, and the TS generates a response authentication token using a session identifier and the security context (S10.7). The TS sends a response comprising the response authentication token to the MS such that the response is delivered to the MS over a signalling channel of the PLMN using a mobile subscriber integrated services digital network-number (MSISDN) associated with the subscriber or subscription to direct the message (S10.9). The MS authenticates the response using the response authentication token, the security context, and the session identifier (S10.12) in order to authenticate the PLMN.Type: ApplicationFiled: December 17, 2012Publication date: November 19, 2015Inventors: Göran Selander, Harald Kallin, Michael Liljenstam, Gunnar Mildh, Bernard Smeets

Patent number: 9161283Abstract: A method in a radio network node (105) for handling handover of a user equipment (110) from a first cell (115) to a second cell (120) is provided. A first scenario (410, 510), associated with a radio quality of the first cell (115) and a radio quality of the second cell (120), and a second scenario (420, 520), associated with a radio quality of the first cell (115) and a radio quality of the second cell (120), are defined.

Publication number: 20150043386Abstract: A set of reporting features are specified for implementation by lower-level Self-Optimizing Network (SON) functions to support the observation of network SON algorithms by high-level SON functions (e.g., OAM functions). The lower-level SON functions may be operative to adjust local parameters related to the network element serving area and/or capacity. The reported SON algorithm events and measurements can be defined such that they can be used by the higher-level SON function to resolve conflicts and control the lower-level SON functions. Some embodiments specify SON function reporting features and their configuration in the framework of the 3GPP defined Itf-N interface specification.Type: ApplicationFiled: February 22, 2013Publication date: February 12, 2015Inventors: András Rácz, Mehdi Amirijoo, Fredrik Gunnarsson, Harald Kallin, Johan Moe

Publication number: 20150031361Abstract: The disclosure relates to a method and radio base station for sharing resources in a wireless communication system. The radio base station stores an identity of a first entity to which a first plurality of UEs is associated. The first plurality of UEs has full access to resources provided by the radio base station. The radio base station also stores an identity of a second entity to which a second plurality of UEs is associated. The second plurality of UEs has partial access to the resources provided by the radio base station. When the radio base station receives a request for accessing resources from a UE, it determines whether the UE is associated with the second entity, i.e. if the UE is to be handled in support mode. If the UE is associated with the second entity it means that the UE only should have partial access to the resources.Type: ApplicationFiled: February 9, 2012Publication date: January 29, 2015Applicant: Telefonaktiebolaget L M Ericsson (publ)Inventors: Bogdan Timus, Harald Kallin, Gunnar Mildh

Publication number: 20140066074Abstract: A radio network node and method for improved control of handover decisions of a User Equipment (UE) in a wireless communications network. The UE is in a served cell and is moving towards a neighboring cell.

Patent number: 8494526Abstract: In a Long Term Evolution (LTE) cellular radio system method of selecting a physical cell id (PCI) of a LTE cell is obtained by reporting PCIs of neighbors and also a parameter indicating each neighboring cell's relevance also termed visibility to the cell. A new cell added in a cellular radio, system can then make an improved selection of a PCI already at the very first neighbor relation establishment; even if all available PCIs are already used in the vicinity.Type: GrantFiled: March 19, 2009Date of Patent: July 23, 2013Assignee: Telefonaktiebolaget L M Ericsson (publ)Inventors: Harald Kallin, Johan Moe

Patent number: 8396480Abstract: In a multi-access system, an access selection principle is achieved by selecting a signal strength threshold level based on a determined load level (ULOCAL) in a first access network. A new user in an area commonly covered by more than one access network attempts to allocate to the first access network if an experienced signal strength exceeds the signal strength threshold level. Communication utility can preferably be maximised or at least be taken into account by using suitable load level dependencies. By increasing the threshold when the load level approaches the capacity limit, a completely filled first access network is avoided. This gives an opportunity to let particularly well-suited users still have access to the first access network. At the same time, since the preferred access is decided before the actual access attempt, control signalling can be significantly reduced, even at very high traffic loads.Type: GrantFiled: January 13, 2005Date of Patent: March 12, 2013Assignee: Telefonaktiebolaget L M Ericsson (publ)Inventors: Mikael Prytz, Anders Furuskär, Jonas Pettersson, Arne Simonsson, Harald Kallin

Publication number: 20120302235Abstract: The present invention relates to a cellular communications network and in particular to the problem of identifying cells for neighbour lists, or handover candidates when the cells are identified by a limited number of non-unique identities. The present invention includes a method for a radio base station, wherein the base station receives reports from one ore more terminals in neighbour cells quality and non-unique identities. The match is sought in a neighbour cell list non-unique identity with a unique cell identity. If the match cannot be made without ambiguity, the base station orders the terminal to detect the unique cell identity. If the reason for the ambiguity is the particular cell is not included in the neighbour cell it is included when its unique identity has been established. The uniquely identified cell is used if a handover is decided.Type: ApplicationFiled: May 30, 2012Publication date: November 29, 2012Inventors: Johan Moe, Harald Kallin
