Publication number: 20220053332Abstract: Systems and methods of providing secondary authentication credentials for an external network are described. The credentials are provided from the UE to the GGSN via the SGSN during establishment of a PDN connection for the UE in a NAS message. The SGSN receives an Activate PDP Context Request from the UE and sends to the GGSN a Create PDP Context Request. The Requests include a PCO IE with the credentials. The GGSN determines a RADIUS and/or DHCP server to be used for IP address allocation, a protocol to be used with the server, and security features to use to dialogue with the server. The GGSN obtains the IP address from the server and provides the IP address to the UE via the SGSN via Create PDP Context Response.Type: ApplicationFiled: November 27, 2019Publication date: February 17, 2022Inventors: Muthaiah VENKATACHALAM, Abhijeet Ashok KOLEKAR, Sharada RAGHURAM, Roy UBRY

Patent number: 8855596Abstract: Emergency call placement methods and apparatus for a user equipment in a wireless network are disclosed. The placement method includes detecting initiation of an emergency call during a non-idle connection mode of the user equipment (204), terminating the non-idle connection mode (206) and initiating a new connection for the emergency call (208). This method allows the new connection to use a location methodology to locate the user equipment in response to the emergency call. The disclosed wireless user equipment (102, 500) is configured to implement the disclosed method.Type: GrantFiled: December 3, 2004Date of Patent: October 7, 2014Assignee: Motorola Mobility LLCInventors: Sharada Raghuram, Donald A.

Patent number: 8818359Abstract: A mobile station (MS) is provided that includes one or more memory devices that maintain a RAT preference rule and that include a removable memory device (RMD) that maintains a data file that includes a prioritized listing of one or more PLMN/RAT combinations. The MS detects a RAT and a PLMN broadcasting on that RAT and determines a type of the RMD. When the RMD is a type that would maintain information on the detected RAT, the MS determines a priority of the detected PLMN/RAT combination relative to other PLMN/RAT combinations based solely on the prioritizations included in the data file. When the RMD is a type that would not maintain information on the detected RAT, the MS determines a priority of the detected PLMN and RAT relative to other PLMN/RAT combinations based on the RAT preference rule in conjunction with the listing of PLMN/RAT combinations in the data file.Type: GrantFiled: March 2, 2012Date of Patent: August 26, 2014Assignee: Motorola Mobility LLCInventors: Xiaofeng Bai, Donald A.

Patent number: 7519365Abstract: A method for a radiotelephone to search for a high priority, home, or home-equivalent public land mobile network (PLMN) includes a first step of registering and camping (300) the radiotelephone on a cell of visited PLMN. A next step includes uniquely identifying (302) the cell. A next step includes searching (304) for PLMNs with a higher priority than the visited PLMN while registered and camped on the uniquely identified cell. A next step includes storing (306) a history of those frequencies found that are not of a higher priority PLMN for the uniquely identified cell. Any subsequent searches for frequencies of higher priority PLMNs performed while registered and camped on that cell includes scanning (308) for available frequencies except for those frequencies listed in the history for the uniquely identified cell in which the radiotelephone is registered and camped.Type: GrantFiled: May 1, 2007Date of Patent: April 14, 2009Assignee: Motorola, IncInventors: Donald A.

Publication number: 20080287127Abstract: A wireless device (105) for scheduling a forward access channel measurement occasion (FMO) includes a transmitter (202) to transmit radio signals required to perform random access channel (RACH) transmission (RACHing) and report the results of cell measurements. A receiver receives radio signals required to acquire information blocks, serving cell selection criteria, and measurement rule parameters, and to measure at least one of inter-frequency and inter-radio access technology (inter-RAT) neighbor cells. A scheduling module (212, 214, 216) schedules FMO frames for neighbor cell measurement in order to prioritize FMO frames that collide with a position of an information block or that collide with RACHing.Type: ApplicationFiled: May 15, 2007Publication date: November 20, 2008Applicant: Motorola, Inc.Inventors: Ping Wu, Donald A.

Patent number: 7333795Abstract: An emergency call placement method (300) used in user equipment in idle mode camped on a first cell of a wireless communication network having a first radio access technology includes the steps of requesting (316) a radio resource control connection using “emergency call” as an establishment request, changing (340, 350) to a new cell in a different location area or routing area than the first cell, and requesting again (316) a radio resource control connection using “emergency call” as an establishment request. This method avoids performing a location area update or a routing area update when the user equipment changes to a new cell during an emergency call and thus may speed up placement of the emergency call by several seconds.Type: GrantFiled: October 24, 2003Date of Patent: February 19, 2008Assignee: Motorola Inc.Inventors: Donald A.

Patent number: 7231213Abstract: While engaged in a dedicated channel, a User Equipment (UE) may get stuck on it. A method and the computer program product detects whether the UE is stuck on the dedicated channel (202). When it is detected that the UE is stuck, the UE or the corresponding network in which the dedicated channel is located carries out a local release of the UE from the dedicated channel (204), and the UE is placed in idle mode (206). Locally releasing the UE from the dedicated channel curtails unnecessary battery consumption in the UE and limits wastage of network resources and bandwidth.Type: GrantFiled: June 30, 2005Date of Patent: June 12, 2007Assignee: Motorola Inc.Inventors: Donald A.

Publication number: 20060099970Abstract: A method and system of providing a log of mobile station geographic location requests is useful for protecting the privacy of mobile station users. The method is performed on a mobile station and includes receiving in the mobile station a location request from a requestor, the location request seeking the geographic location of the mobile station. It is then determined whether the location request is a Mobile Terminated Location Request (MTLR), a Network Initiated Location Request (NILR), or a Mobile Originated Location Request (MOLR). Log information about the location request is then stored and it is determined whether the mobile station has local privacy settings that apply uniquely to the requestor. The location request is then responded to in accordance with local privacy settings, and log information about the response to the location request is stored.Type: ApplicationFiled: November 10, 2004Publication date: May 11, 2006Inventors: Scott Morgan, Eric Hefner, Mary Hor-Lao, Dale Neuzil, Sharada Raghuram, Michelle Xiong
