Patent number: 8554266Abstract: Mobile user equipment for use in a cellular communications environment performs an improved cell selection on transitions out of a connected mode state. The transitions might be from one connected mode state to another or from a connected mode state to idle mode. The improvement in cell selection lies in assembling the list of candidate cells prior to cell selection. In the prior art, the list of candidate cells would usually be restricted to the serving cell or active cells supporting communication between the equipment and the network prior to transition. In embodiments of the invention, the list might comprise cells which are not the serving cell or which are outside the active set, for example a network-preferred cell or cells neighboring the serving cell or cells of the active set.Type: GrantFiled: February 15, 2011Date of Patent: October 8, 2013Assignee: BlackBerry LimitedInventors: Nicola M. Funnell, Gideon Roberts, Andrew John Farnsworth, Richard John George, Gjalt de Jong

Patent number: 7596379Abstract: The present invention concerns a method for maintaining transparent mode radio bearers in a Radio Access Network (RAN) of a third generation mobile telecommunications network. The method relates to managing the radio resources allocated to a user equipment (UE) in said radio access network (RAN). The method generally comprises communicating a message from a radio resource controller (RRC) of the RAN to the UE where said message is arranged to instruct the UE to transition from a dedicated channel connection state to a lower activity connection state and to store in its memory transparent mode (TM) radio bearer (RB) information associated with said dedicated channel connection state. By storing TM RB information associated with the dedicated channel connection state, the UE can be reconfigured to the dedicated channel connection state without the RAN having to perform a radio bearer setup procedure.Type: GrantFiled: August 16, 2004Date of Patent: September 29, 2009Assignee: M-Stack LimitedInventors: Andrew John Farnsworth, Gjalt de Jong

Patent number: 7525908Abstract: In Radio Link control (REC) apparatus, a mechanism is provided for detecting missing or corrupted data units at the receiving end of a transmission link, requesting retransmission and then monitoring the response to the retransmission request. Distinctively, a receiving communications entity 300 is equipped to act on a nil response. If no data unit is retransmitted, the receiving entity triggers at least one repeat retransmission request. This is the case even if no further data unit is received after the retransmission request is triggered. Retransmission requests are repeated up to a preset number, whereafter a different recovery mechanism is triggered.Type: GrantFiled: September 24, 2004Date of Patent: April 28, 2009Assignee: M-Stack LimitedInventors: Patrik Olsson, Gjalt de Jong

Publication number: 20070254666Abstract: A multi-mode mobile communication device may include a processing device, a memory sub-system, a communication sub-system operable to communicate with the plurality of wireless access networks, and a protocol stack stored in the memory sub-system and executed by the processing device. The protocol stack may include a first access stratum, a second access stratum, a non-access stratum and an access stratum manager. The first access stratum may communicate with a first wireless access network via the communication sub-system. The second access stratum may communicate with a second wireless access network via the communication sub-system. The non-access stratum may communicate with a core network. The access stratum manager may interface the non-access stratum with the first and second access strata, and may be operable to activate the first access stratum to establish a communication link with the core network over the first wireless access network.Type: ApplicationFiled: June 22, 2007Publication date: November 1, 2007Applicant: M-STACK LIMITEDInventors: GJALT DE JONG, GERALD KELLIHER, ROBERT HARRISON

Patent number: 7184760Abstract: Air interface management apparatus for use in network-based control of measurements made by mobile user equipment with respect to cells of the network is adapted to detect conflict in content of measurement control messages instructing the report of pathloss measurement values. Conflict is detected in particular where the message specifies: a) an identity for a triggering event for which the category or categories of cell to be measured is determined at the receiver solely by said identity and comprises detected set cells, or b) periodical measurement in respect of a detected set cell. Pathloss measurements are not possible in these cases. The apparatus provides a mechanism for dealing with detected conflict by blocking transmission of, or response to, a measurement control message giving rise to conflict. Alternatively, the message or the response may be modified to avoid the conflict.Type: GrantFiled: December 29, 2004Date of Patent: February 27, 2007Assignee: M-Stack LimitedInventors: Nicola M.

Publication number: 20060035634Abstract: Apparatus, and an associated method, for identifying availability of services in a radio network of a radio communication system. A system information message is generated at the radio access network that identifies the service availability of the radio network, such as by indicating the communication services supported by the network. The system information message, once generated, is communicated upon a broadcast control channel, or other appropriate channel, and delivered to a mobile node. The mobile node detects the system information message and determines the availability of services of the radio network therefrom. Selection of whether to register with the network is made responsive to whether the network supports the communication service that the mobile node intends to initiate.Type: ApplicationFiled: August 13, 2004Publication date: February 16, 2006Inventors: Craig Swann, Joseph Deu-Ngoc, Gjalt de Jong

Publication number: 20050070253Abstract: A method and apparatus for processing a message in a mobile telecommunications device. The method comprises: receiving a Cell Update Confirm (CUC) message; determining whether the device has an empty C_RNTI variable; when the device has an empty C_RNTI variable, determining whether the CUC message includes a new C_RNTI; when the CUC message includes a new C_RNTI and the CUC message would cause the device to enter a state which requires the UE to respond to the message before entering the state, carrying out at least one further step prior to entering the state.Type: ApplicationFiled: September 29, 2003Publication date: March 31, 2005Inventors: Andrew Farnsworth, David Pedlar, Gjalt de Jong
