Patent number: 7089002Abstract: An omnibus connection release message transmitted from a control node of radio access network is used to release plural radio connections, thereby obviating problems attending transmission of plural release messages. In accordance with a first example, a control node of the radio access network prepares the omnibus release message so that, when a first selected parameter thereof has a predetermined value, all radio connections controlled by the radio network control (RNC) node are released. The first selected parameter can be included in a mobile terminal global identity information element of the omnibus release message (e.g., in a Radio Network Temporary Identity (U-RNTI) information element of the omnibus release message, such as a Serving Radio Network Temporary Identity (S-RNTI) information element).Type: GrantFiled: May 11, 2001Date of Patent: August 8, 2006Assignee: Telefonaktiebolaget LM Ericsson (publ)Inventor: Bo Stefan Pontus Wallentin

Patent number: 7068607Abstract: An architecture for resource management of an IP-based cellular radio access network is presented. A measurement-based admission control scheme is used to monitor the load for each path in the network and QoS (quality of service) class and resource decisions are made based upon that information. A bandwidth broker is introduced in the cellular radio access network (RAN). The bandwidth broker processes the on-demand admission requests for IP resources by using the results of load control measurements. Since the requests can be processed very quickly using a simple table look-up, response times are fast, and the architecture is thus suitable for the cellular environment.Type: GrantFiled: August 29, 2001Date of Patent: June 27, 2006Assignee: Telefonktiebolaget LM Ericsson (publ)Inventors: David Partain, Bo Stefan Pontus Wallentin

Patent number: 6895245Abstract: Telecommunications network decision making (such as call admission and call congestion control) utilizes as input, not only information in the cell where the call is setup, but also cell condition information from cells which neighbor the cell where the call is setup. The cell condition information from neighboring cells is obtained even in situations in which the neighboring cell is controlled by another exchange, e.g., another radio network controller (RNC). In an illustrated embodiment, the cell condition information utilized by the decision making includes measured data taken over at least a multi-connection portion of cell, one example of which is radio interference information. The cell condition information utilized in the network decision making is transmitted between exchanges (e.g., between radio network controllers [RNCs] using common channel signaling.Type: GrantFiled: March 6, 1998Date of Patent: May 17, 2005Assignee: Telefonaktiebolaget LM Ericssion(publ)Inventor: Bo Stefan Pontus Wallentin

Patent number: 6233222Abstract: A telecommunications network has a target exchange (RNC 2222) which determines a congestion condition in a region supervised by the target exchange, and which sends a congestion message to a source exchange (RNC 2221). The source exchange controls at least some connections which utilize radio resources in the region supervised by the target exchange. The congestion message causes the source exchange to adjust at least one connection which it controls in the region supervised by the target exchange. In a first mode of the invention, the target exchange determines a selected connection to be adjusted in view of the congestion condition. In this first mode, the congestion message identifies the selected connection to be adjusted and further includes an adjustment value (e.g., power reduction value) for the selected connection to be adjusted. In a second mode of the invention, the congestion message includes an identification of a congested area (e.g.Type: GrantFiled: March 6, 1998Date of Patent: May 15, 2001Assignee: Telefonaktiebolaget LM EricssonInventor: Bo Stefan Pontus Wallentin

Patent number: 6230013Abstract: In connection with a diversity handling moveover procedure for a cellular system having soft handover, allocation of a replacement diversity handling unit in a target node occurs only after a moveover decision has been made by a source node. Initially, an original or source diversity handling unit at the source node performs connection combining and connection splitting functions for legs of a mobile connection routed through plural base stations serving a mobile station. In accordance with movement of the mobile station, the source node makes the movement decision. The moveover decision can be based on factors such as base station utilization and/or actual and/or predicted directional movement of the mobile station. In some embodiments, the diversity handling moveover procedure involves selection among plural nodes for situs of the replacement or target diversity handling unit.Type: GrantFiled: November 26, 1997Date of Patent: May 8, 2001Assignee: Telefonaktiebolaget LM Ericsson (publ)Inventors: Bo Stefan Pontus Wallentin, Per Hans Åke Willars, Peter Carl Birger Lundh

Patent number: 6154450Abstract: A CDMA mobile telecommunications system comprises a base station (20) having a radio channel connection to a mobile station (22). The base station (20) determines a signal to interference/noise ratio (SINR) with respect to the signal received from the mobile station (22), compares the signal to interference/noise ratio (SNR) for the mobile station (22) with a target signal to interference/noise ratio (TSINR), and transmits a power level command to the mobile station (22) in accordance with the comparison. A mobile switching center (24) generates information for updating the target signal to interference/noise ratio (TSINR)and transmits the information for updating the target signal to interference/noise ratio (TSINR) to the base station (20) using in-band signaling.Type: GrantFiled: August 22, 1997Date of Patent: November 28, 2000Assignee: Telefonaktiebolaget LM EricssonInventors: Bo Stefan Pontus Wallentin, Paul Peter Butovitsch
