Patent number: 11706679Abstract: Apparatuses, systems, and methods for high data mode operation in cellular networks. A UE may determine, for an interface to a high-speed cellular network, a categorization from a plurality of categorizations, determine availability of the high-speed cellular network, and select, based at least in part on the categorization and availability of the high-speed cellular network, the interface for a data connection to the high-speed cellular network. The categorization may be one of expensive or not expensive and/or one of a first level associated with a higher compression codec rate or a second level associated with a lower compression codec rate. The UE may receive, from one of the a low-speed cellular network or the high-speed cellular network, carrier plan information for a cellular data service carrier and analyze the carrier plan information to determine desirability of a switch, e.g., from the low-speed cellular network to the high-speed cellular network.Type: GrantFiled: January 17, 2022Date of Patent: July 18, 2023Assignee: Apple Inc.Inventors: Raghuveer Mallikarjunan, Patrick L Coffman, Madhusudan Chaudhary, Muthukumaran Dhanapal, Ajay Singh, Faraz Faheem, Thanigaivelu Elangovan, Lakshmi N Kavuri, Samuel J Miller, Najeeb M Abdulrahiman, Rajesh Ambati, Arun G Mathias, Vivek Ramanna, Divyaprakash P Bhojkumar, Vikram B Yerrabommanahalli, Rafael L Rivera-Barreto, Sergey Sitnikov, Oleg M Moskalenko, Bao Q Ho, Rohan C Malthankar, Samy Touati

Publication number: 20230209348Abstract: Apparatuses, systems, and methods for a wireless device to perform methods for improvements to security checks in a fifth generation (5G) New Radio (NR) network, including mechanisms to avoid redundant access stratum (AS) security checks. The wireless device may determine that an on-demand system information block (SIB) request is pending transmission and may buffer the on-demand SIB in response to determining that a connection establishment procedure will be initiated within a specified time period. The wireless device may then perform a unified security procedure for the on-demand SIB request and the connection establishment procedure, including confirming connection security. Further, in response to confirming connection security, the wireless device may use an on-demand SIB received from the network without confirming a corresponding on-demand SIB signature.Type: ApplicationFiled: March 7, 2023Publication date: June 29, 2023Inventors: Muthukumaran Dhanapal, Li Su, Vijay Venkataraman
