Patent number: 10389691Abstract: Creation or update of a security context between user equipment and MSC/VLR (Mobile Switching Center/Visitor Location Register) for circuit switched domain services is provided. The creation or update is based on conversion of the security context used in an evolved Universal Terrestrial Radio Access Network (E-UTRAN) in the Mobility Management Entity (MME) to a security context for the circuit switched domain target system and transferring it to a MSC/VLR. When user equipment is moved from E-UTRAN to GSM EDGE Radio Access Network/Universal Terrestrial Radio Access Network (GERAN/UTRAN), a MME does not need to perform authentication and key agreement procedures to establish shared circuit switched security context for the user equipment.Type: GrantFiled: July 31, 2018Date of Patent: August 20, 2019Assignee: QUALCOMM IncorporatedInventors: Xipeng Zhu, Wolfgang Granzow, Adrian Edward Escott

Publication number: 20170064488Abstract: Techniques are described for providing and using customized resource types for machine-to-machine (M2M) communication. Through the use of customized resource types, machine type communication (MTC) devices may be provided with flexibility to receive and process request messages without prior knowledge of a resource type associated with the request messages. A receiving MTC device or infrastructure node, may receive a request to create a resource from a requesting MTC device via wireless or wired communications technologies. The resource type of the request may be a customized resource type, and the request to create the resource may include a resource reference and a content parameter. The resource reference may include, for example, a Uniform Resource Indicator or a Uniform Resource Locator that may be used by the receiving MTC device to retrieve the data associated with the resource. The receiving MTC device may generate the resource using the retrieved data.Type: ApplicationFiled: July 28, 2016Publication date: March 2, 2017Inventors: WOLFGANG GRANZOW, JOSEF JOHANNES BLANZ, NOBUYUKI UCHIDA, PHILIP MICHAEL HAWKES

Patent number: 9445321Abstract: A method, an apparatus, and a computer program product for wireless communication are provided in which a user equipment performs an inter-radio access technology (RAT) mobility procedure from a first network to a second network while idle mode signaling reduction (ISR) is active, locally deactivates ISR in connection with completion of the inter-RAT mobility procedure, and initiates a location management procedure in the second network. Depending on the respective type of the first and second network, and the connection state of the UE with respect to the first network, the mobility procedure may be performed in response to a mobility command received from the first network, or in response to a mobility condition of the first network as detected by the UE.Type: GrantFiled: March 14, 2013Date of Patent: September 13, 2016Assignee: QUALCOMM IncorporatedInventors: Xipeng Zhu, Francesco Pica, Shyamal Ramachandran, Miguel Griot, Mungal Singh Dhanda, Masato Kitazoe, Wolfgang Granzow, Aziz Gholmieh

Patent number: 9083521Abstract: A system is provided for transmitting information through a speech codec (in-band) such as found in a wireless communication network. A modulator transforms the data into a spectrally noise-like signal based on the mapping of a shaped pulse to predetermined positions within a modulation frame, and the signal is efficiently encoded by a speech codec. A synchronization sequence provides modulation frame timing at the receiver and is detected based on analysis of a correlation peak pattern. A request/response protocol provides reliable transfer of data using message redundancy, retransmission, and/or robust modulation modes dependent on the communication channel conditions.Type: GrantFiled: June 3, 2009Date of Patent: July 14, 2015Assignee: QUALCOMM IncorporatedInventors: Christian Sgraja, Marc W. Werner, Christian Pietsch, Wolfgang Granzow, Nikolai K N Leung, Christoph A. Joetten, Pengjun Huang

Patent number: 9049629Abstract: Systems and methodologies are described that facilitate inter-system handover in a wireless communication system. Various aspects described herein provide for handover techniques that enable a target system to be prepared by a mobile device via a source system in order to minimize specific changes required to source system and/or target system. Techniques are described herein in which the radio link of a source system can be utilized to tunnel signaling messages which are in a format understood by a destination node in a target system. Further, fast inter-access handover can be facilitated by establishing a simple generic transmission tunnel between respective network nodes in source and target systems that handle intra-system mobility and providing a Layer 2 (L2) tunneling mechanism over the radio interface of each involved system technology.Type: GrantFiled: June 17, 2008Date of Patent: June 2, 2015Assignee: QUALCOMM IncorporatedInventors: Kalle I. Ahmavaara, Lorenzo Casaccia, George Tsirtsis, Wolfgang Granzow
