Patent number: 9049607Abstract: A method automatically initializes a mobile station during a test between a mobile station and test equipment emulating a single cell of a cellular mobile communication system, wherein the mobile station is initially registered to the cell having a first location area code. First, radio transmission into the cell is terminated by the test equipment. Then, radio transmission is restarted into the cell, but now having a second location area code, wherein the second location area code is different than the first location area code, forcing the mobile station to perform a registration procedure to the cell.Type: GrantFiled: October 18, 2013Date of Patent: June 2, 2015Assignee: ROHDE & SCHWARZ GMBH & CO.

Patent number: 8260202Abstract: In a case where an access point lies outside the direct radio transmission range of a first radio station of a radio communications system, and a routing runs between the first radio station and the access point that includes at least one additional radio station is known to the first radio station and the access point, information can be transmitted from the first radio station to the access point and from the latter to the first radio station via the routing. When the access point receives information relating to an interruption in the known routing from a radio station in the routing, the first radio station downstream of the access point is informed of the interruption in the known routing and subsequently initiates a process for determining a new routing between the first radio station and the access point.Type: GrantFiled: October 21, 2004Date of Patent: September 4, 2012Assignee: Nokia Siemens Networks GmbH & Co.

Publication number: 20070021064Abstract: In a radio communication system formed of a central radio station and subscriber radio stations each having a radio transmission range, the subscriber radio stations are at least partially mobile and each radio station is disposed within the radio transmission range of at least one adjacent subscriber radio station. User data is sent from radio station to radio station within the range of a subscriber radio station in order to transfer user data. User data can be transferred directly or can be transferred via one or several other radio stations from any particular first subscriber radio station to any particular second subscriber radio station in the radio communication system. The central radio station transmits information via the adjacent subscriber radio stations of each subscriber radio station within at least one part of the radio communication system to the plurality of subscriber-sided radio stations within the at least one part of the radio communication system.Type: ApplicationFiled: February 9, 2004Publication date: January 25, 2007Inventors: Ingo Gruber, Hui Li

Publication number: 20060009149Abstract: In a radio communication system which incorporates numerous radio stations, messages are transmitted along a path from a first radio station to a second radio station via one or more radio stations which forward the messages. At least one radio station on the path sends a first signaling message to the radio station which is neighboring to it along the path towards the first radio station. This signaling message contains data about the maximum transmission resource access rate to be used for sending messages to the one or more radio station.Type: ApplicationFiled: May 18, 2005Publication date: January 12, 2006Applicant: SIEMENS AKTIENGESELLSCHAFTInventors: Andreas Baessler, Ingo Gruber, Hui Li
