Publication number: 20050100078Abstract: In a telecommunications system that employs frequency hopping techniques, network performance can be significantly improved by taking into consideration the level of interaction (e.g., the collision rate) between frequency hopping sequences, when allocating the frequency hopping sequences throughout the network. In a cellular network, this may be accomplished by deriving a network performance measure as a function of a current allocation of frequency hopping sequences for a number of cells and as a function of an expected collision rate (between the frequency hopping sequences) that appear for the current allocation. The frequency hopping sequences are then re-allocated amongst one or more cells until network performance is optimized. The allocation of frequency hopping sequences that results in optimized network performance may then be used for assigning frequency hopping sequences to new or existing connections (e.g., cellular calls) within a corresponding cell.Type: ApplicationFiled: December 9, 2004Publication date: May 12, 2005Inventors: Henrik Nyberg, Stephen Craig, Sverker Magnusson, Erik Edgren

Patent number: 6671309Abstract: In a cellular radio telecommunications system that employs frequency hopping, system performance can be significantly improved by more fully exploiting interference diversity, while maintaining frequency diversity, which is already associated with frequency hopping techniques. In order to more fully exploit interference diversity, each mobile station operating in a cell is allocated, in addition to a frequency hopping sequence, a frequency offset hopping sequence such that each mobile station hops from one frequency to the next frequency as a function of the frequency hopping sequence and its allocated frequency offset hopping sequence. This technique is readily applicable to increase both intercell and intracell interference diversity in unsynchronized or synchronized cells.Type: GrantFiled: June 26, 2000Date of Patent: December 30, 2003Assignee: Telefonaktiebolaget LM Ericsson (publ)Inventors: Stephen G.

Publication number: 20030212798Abstract: Users of a given service in a wireless communication system that includes a plurality of multi-service subsystems are allocated to one of the subsystems in accordance with a combined capacity region of the wireless communication system. The combined capacity region is determined based upon capacity regions of each of the plurality of multi-service subsystems. The capacity regions of the plurality of multi-service subsystems are determined using a relative decrease in users of a first service as a function of an increase in users of a second service.Type: ApplicationFiled: April 1, 2003Publication date: November 13, 2003Inventors: Anders Furuskar, Magnus Almgren, Sverker Magnusson, Arne Simonsson, Per Magnusson

Patent number: 6285874Abstract: The present invention relates generally to the problem of determining the identity of a cell for e.g. cell handoff or automatic frequency planning, and more particularly to the problem of determining the true identity of a cell when only the transmission frequency and a non-unique identity code is known. A candidate list is created for each cell. This candidate list is created based on a function of various elements e.g. distance, transmission power, cell type, and antenna placement. The cells are then ranked on the candidate list based on this function. When a particular frequency/code combination is detected, the candidate list is then consulted, and the highest ranking cell with the same frequency/code combination is chosen as being the signal source. In an alternative embodiment the neighbor cell list is used to create the candidate list.Type: GrantFiled: November 20, 1998Date of Patent: September 4, 2001Assignee: Telefonaktiebolaget LM Ericsson (publ)Inventors: Sverker Magnusson, Håkan Olofsson, Katarina Isaksson, Stephan Trzeciak

Patent number: 6233270Abstract: In a synchronized, cellular radio telecommunications system that employs frequency hopping, system performance can be significantly improved by more fully exploiting interference diversity, while maintaining frequency diversity, which is already associated with frequency hopping techniques. In order to more fully exploit interference diversity, each cell belonging to a group of synchronized cells in the cellular radio telecommunications system is allocated a common, reference frequency hopping sequence. However, the various mobile stations operating in any one of these cells is allocated a different frequency offset hopping sequence.Type: GrantFiled: September 28, 1999Date of Patent: May 15, 2001Assignee: Telefonaktiebolaget LM Ericsson (publ)Inventors: Stephen G.

Patent number: 6212384Abstract: The source cell of a radio signal broadcast within a cellular radio network is determined by several alternative techniques. Each involves either a mobile station or a base station broadcasting a system-unique identity signal from which the network can determine the source of the signal. From the unique source of the signal the network can determine the geographic source from which the signal originated and use that information to perform automatic system administration functions, such as, prepare a best neighbor list or perform frequency planning and allocation for the network.Type: GrantFiled: September 29, 1997Date of Patent: April 3, 2001Assignee: Telefonaktiebolaget L M Ericsson (publ)Inventors: Knut Magnus Almgren, Håkan Gunnar Olofsson, Sverker Magnusson

Patent number: 6163524Abstract: In spread spectrum communications, a method for allocating and re-allocating channelization codes to new and existing channels in a way that makes the maximum number of codes available at a given time for channels of different rates and different spreading factors. If re-allocations are not performed, a communication system employing the invention has a higher capacity than a system employing a random allocation strategy. The invention also reduces signaling overhead for re-allocations in comparison to a random allocation strategy because fewer re-allocations are necessary.Type: GrantFiled: October 19, 1998Date of Patent: December 19, 2000Assignee: Telefonaktiebolaget LM Ericsson (publ)Inventors: Sverker Magnusson, Farooq Khan, Magnus Persson, Per Beming

Patent number: 5898928Abstract: In a telecommunications network, a method and apparatus for allocating channels makes signal quality measurements for channels that are in use or available for use and for channels that may become available for use. Already selected channels (i.e., channels in use or available for use) that exhibit poor signal quality characteristics are exchanged with candidate channels (i.e., channels that may become available for use) that exhibit better signal quality characteristics to thereby improve the overall signal quality of the network.Type: GrantFiled: February 29, 1996Date of Patent: April 27, 1999Assignee: Telefonaktiebolaget LM EricssonInventors: .ANG.ke Karlsson, Daniel Bringby, Patrik Karlsson, Sverker Magnusson
