Publication number: 20230254676Abstract: There is provided mechanisms for profile handling of a communication device. A method is performed by a subscription server. The method comprises obtaining device type information of the communication device from a proxy server. The method comprises determining a profile handling action for the communication device according to at least one localization rule. According to which of the localization rule the profile handling action is determined depends on a mapping between the device type information and the localization rule. The method comprises notifying the proxy server of the profile handling action.Type: ApplicationFiled: July 1, 2020Publication date: August 10, 2023Inventors: Per Ståhl, Qiang LI, Juha Sääskilahti, John Fornehed, Bernard Smeets

Patent number: 11316820Abstract: There is provided mechanisms for handling registration of data packet traffic for a wireless device in a communications network. A method is performed by a core network node. The method comprises registering an amount of data packet traffic in the communications network for the wireless device, wherein each data packet comprises an address of the wireless device, wherein the address is mapped to an identity of the wireless device, wherein the address comprises a first part defining an identity of a local network gateway of the wireless device and a second part defining the identity of the wireless device, and wherein selection of the second part is independent from the first part and the identity of the local network gateway. The method comprises mapping the amount of data packet traffic to the identity of the wireless device.Type: GrantFiled: April 14, 2016Date of Patent: April 26, 2022Assignee: Telefonaktiebolaget LM Ericsson (publ)Inventors: Per Ståhl, John Fornehed, Ari Keränen, Anders Nohlgren, Bernard Smeets

Patent number: 11101978Abstract: A method (100) for establishing a new identity for a constrained device is disclosed, wherein the device has an existing identity and is associated with an asymmetric key pair comprising a device public key and a device private key. The method comprises applying a hash function to the existing identity (106) and setting the resulting value as the new identity for the constrained device (108), wherein the existing identity comprises at least a first generation hash value of a hash chain formed by applying the hash function to the device public key. Also disclosed is a method (200) for managing an identity of a constrained device, the device being associated with an asymmetric key pair comprising a device public key and a device private key.Type: GrantFiled: February 18, 2015Date of Patent: August 24, 2021Assignee: TELEFONAKTIEBOLAGET LM ERICSSON (PUBL)Inventors: Patrik Salmela, John Fornehed

Patent number: 9819769Abstract: A scheme for providing access to 6LoWPAN data in a wireless access network comprising a Digital Unit (DU) coupled to one or more Radio Units (RU) via CPRI links, each RU in turn coupled to one or more radio dot (RD) elements via Ethernet cable links. In one embodiment, an RD element includes a cable front-end interfaced with the Ethernet cable link, a radio front-end interfaced between the cable front-end and an antenna or a suitable access point. A sensor component may be included that is configured to generate sensor data with respect to a measurement variable, which sensor data may be packaged in a 6LoWPAN data format for transmission to the RU element coupled to the RD element.Type: GrantFiled: April 20, 2016Date of Patent: November 14, 2017Assignee: Telefonaktiebolaget LM Ericsson (Publ)Inventors: Samita Chakrabarti, John Larkins, Jaume Rius I Riu, John Fornehed, Chenguang Lu

Patent number: 9814063Abstract: A scheme for providing access to 6LoWPAN data in a Pico-Remote Radio Unit (PRRU)-based wireless access network. In one embodiment, the PRRU network comprises a Baseband Unit (BBU) coupled to one or more remote Radio Hub (RHUB) elements via a first set of CPRI links, each RHUB element in turn coupled to one or more PRRU elements via corresponding second sets of CPRI links. The BBU element comprises an interface for communicating 6LoWPAN data to and from a router coupled to an IPv6 network. The BBU element also includes a bridging functionality operative to determine endpoint PRRU elements' addresses and corresponding RHUB elements' addresses by querying an address mapping database.Type: GrantFiled: April 1, 2016Date of Patent: November 7, 2017Assignee: Telefonaktiebolaget LM Ericsson (Publ)Inventors: Samita Chakrabarti, John Larkins, Jaume Rius I Riu, John Fornehed, Chenguang Lu

Patent number: 9497116Abstract: A scheme for providing access to 6LoWPAN data in a wireless access network. In one embodiment, a Digital Unit (DU) of the wireless access network is provided with IP bridging functionality for packaging 6LO data as a control channel message. When the DU element receives 6LO data from an external router, the data is packaged in a format specified for a control channel associated with a CPRI link coupling to a Radio Unit (RU). The bridging functionality is operative to transmit the control channel message (including the packaged 6LO data packets) to the RU element based on an address mapping between the destination IP address of the 6LO data packets and an address of the 6LO endpoint coupled to the RU element.Type: GrantFiled: February 21, 2014Date of Patent: November 15, 2016Assignee: Telefonaktiebolaget LM Ericsson (publ)Inventors: Samita Chakrabarti, John Larkins, Jaume Rius I Riu, John Fornehed, Chenguang Lu
