Patent number: 9681292Abstract: Techniques for handling ciphering keys in a mobile station comprising a mobile equipment (ME) and a Universal Subscriber Identity Module (USIM) are disclosed. An example method includes obtaining a UMTS cipher key (CK), integrity key (IK), and ciphering key sequence number (CKSN) from the USIM, deriving a 128-bit ciphering key (Kc-128) from the CK and the IK, and storing the Kc-128 and the CKSN on the mobile equipment, separate from the USIM. The stored CKSN is associated with the stored Kc-128, so that the Kc-128's correspondence to the most current UMTS security context can be tracked. This example method applies to the generation and storage of a 128-bit ciphering key for either the packet-switched or circuit-switched domains. A corresponding user equipment apparatus is also disclosed.Type: GrantFiled: August 17, 2010Date of Patent: June 13, 2017Assignee: Telefonaktiebolaget LM Ericsson (publ)Inventors: Christian Herrero Verón, Monica Wifvesson

Patent number: 8619665Abstract: Solutions are described that enable a user equipment (UE) for a communication system always to derive required identifiers using an international mobile subscriber identity (IMSI) even when the UE has only a subscriber identity module. One solution is based on a table, or list, that is maintained in the UE. Another solution is based on always taking a predetermined number of digits of the IMSI. Yet another solution is based on try-and-fail signaling. In consequence, the UE does not always need to know how many digits of the IMSI are used to indicate a mobile network code, which in some situations is impossible to know anyway.Type: GrantFiled: December 22, 2007Date of Patent: December 31, 2013Assignee: Telefonaktiebolaget L M Ericsson (publ)Inventors: Anne-Lott Hedberg, Christian Herrero Verón, Regina Johannesson

Patent number: 8422998Abstract: A technique is provided for use by a user terminal or mobile services switching center (MSC) for responding to a request to switch an on-going call from speech mode to multimedia mode within a wireless communication network conFig.d to automatically disconnect a call if a requested mode switch is not confirmed within a predetermined period of time specified by a call drop timer. In one example, the terminal or MSC activities an automatic response timer upon receipt of a request from a user to switch an on-going call from speech to multimedia, with the timer set shorter than the call drop timer. The user receiving the request is then prompted to accept or decline the request. If no response is received before expiration of the automatic response timer, the terminal or MSC automatically declines the request on behalf of the user so that the call drop timer does not expire.Type: GrantFiled: January 31, 2005Date of Patent: April 16, 2013Assignee: Telefonaktiebolaget L M Ericsson (publ)Inventors: Christian Herrero Verón, Patrice Hédé, John Kerr

Patent number: 8289848Abstract: A method, device management server, Packet Data Network Gateway (PDN GW) and User Equipment (UE) for establishing a PDN connection having defined packet flow limitations from a UE to a PDN GW. When a misbehaving or malicious UE is operating in the Evolved Packet System (EPS), the invention enables the UE to retain a PDN connection with an EPS bearer open until the software in the UE has been updated. The server sends to the UE, a management object that includes a logic parameter (packet filters) for controlling a packet flow from the UE to the network, or a defined Access Point Name (APN) that enables the UE to obtain the packet filters from a PDN GW. In turn, the UE sends to the network, a request for a new PDN connection while requesting deactivation of any previously existing PDN connections. The UE transmits on the new PDN connection, only packets allowed by the logic parameter.Type: GrantFiled: January 27, 2010Date of Patent: October 16, 2012Assignee: Telefonaktiebolaget LM Ericsson (publ)Inventors: Peter Hedman, Christian Herrero Verón

Patent number: 8155651Abstract: A user equipment (UE) includes a resettable timer that clocks a period after a successful packet-switched handover in a communication system. If a command message for setting packet-data transmission parameters is not received from the network before the period elapses, the UE starts a transmission-parameter negotiation if the UE wishes to do so. In this way, a UE can negotiate optimal parameters for packet-data transmission.Type: GrantFiled: June 25, 2007Date of Patent: April 10, 2012Assignee: Telefonaktiebolaget L M Ericsson (publ)Inventors: Regina Johannesson, Christian Herrero-Verón

Patent number: 8139530Abstract: A system and method for using Mobility Management (MM) and Session Management (SM) procedures in an SAE/LTE system. The present invention modifies several MM and SM procedures that have been defined for other 3GPP access systems (such as GERAN, UTRAN) so that they meet the requirements of LTE/SAE. While the present invention re-uses some existing procedures, it further defines new protocols for MM and SM procedures when accessing 3GPP systems by Evolved UTRAN (EUTRAN). With respect to the new protocols, the encoding rules are re-used from the existing MM and SM procedures and a very similar general message format is created. With respect to the signaling messages, the present invention re-uses the existing information element definitions for each parameter included in a message.Type: GrantFiled: March 5, 2008Date of Patent: March 20, 2012Assignee: Telefonaktiebolaget L M Ericsson (Publ)Inventor: Christian Herrero-Verón

Patent number: 7873357Abstract: Network services and/or network capabilities in a mobile terminal operating in a mobile communications system are selectively enabled. This involves receiving an information element encoded to indicate whether each of a number of network services and/or network capabilities is enabled or disabled. The information element is then stored in the mobile terminal. The mobile terminal is then operated in a way that inhibits the mobile terminal from requesting all network services and network capabilities that are indicated by the information element as being disabled. The information element may optionally include a text string and/or a customer service number to be displayed to a user of the mobile terminal for the purpose of assisting the user in determining the cause of the non-availability of one or more services and/or capabilities.Type: GrantFiled: October 26, 2005Date of Patent: January 18, 2011Assignee: Telefonaktiebolaget L M Ericsson (publ)Inventor: Christian Herrero Verón
