Publication number: 20050250505Abstract: In an implementation of multiple simultaneous calls for a mobile station in a mobile communication system, a common traffic channel is allocated to several simultaneous calls of the mobile station, so that the calls share capacity of the common channel. Logical links are established for each call inside a common radio link protocol or link access control protocol, established over the common traffic channel between the mobile station and an interworking function. The common traffic channel is allocated when the first call or calls are set up, and the capacity of the traffic channel is adjusted dynamically during the calls. The common traffic channel capacity is increased or the allocated capacity is reallocated when a new call is added to the traffic channel. Correspondingly, the capacity is decreased or reallocated when a call is cleared from the common traffic channel.Type: ApplicationFiled: July 14, 2005Publication date: November 10, 2005Applicant: Nokia Networks OyInventor: Juha Rasanen

Patent number: 6920317Abstract: A mobility support element (MSC/VLR; SGSN, GGSN) for a cellular radio network supporting circuit-switched and packet-switched connections to/from a mobile station (MS). For each mobile station (MS), there is a set (LSA1, LSA2) of special cells (C1-C3, C9, C10) providing special service. A radio control element (BSC1, BSC2) determines whether the mobile station (MS) is in a special cell. Charging elements (CG, BC) receive charging information comprising detail items which indicate events which affect charging. The mobility support element (MSC/VLR; SGSN, GGSN) receives, when it begins to serve the mobile station, a list (LSA1, LSA2) of the special cells for the mobile station, and sends the list to the serving radio control element (BSC1, BSC2). The mobility support element also supports or performs classification of the detail items into two classes depending on whether or not the corresponding event occurred while the mobile station was in a special cell.Type: GrantFiled: September 14, 1999Date of Patent: July 19, 2005Assignee: Nokia Networks OyInventor: Ahti Muhonen

Patent number: 6915116Abstract: The present invention is based on the idea that the base transceiver station can make a decision as to changing transmission diversity in response to the power control message sent by the mobile station. The decision to change transmission diversity is made, for instance, on the basis of the result obtained from filtering the power control requests. For example, filtering can be carried out using a sliding window that contains power control information on the basis of which the decision is made. It is not necessary for the mobile station to transmit a special request to change transmission diversity; instead, the decision on changing transmission diversity is made by the base transceiver station in response to the power control information that the mobile station would, in any case, send to the base transceiver station.Type: GrantFiled: April 25, 2001Date of Patent: July 5, 2005Assignee: Nokia Networks OyInventors: Yan Ivan Wang, Risto Wichman
