Patent number: 10749667Abstract: A method and system for providing GTP acceleration for secure cellular backhaul over satellite (CBoS). A satellite terminal receives request from a first entity to establish a security association with a second entity, and establishes a first secure tunnel to a gateway. A second secure tunnel is then established between the gateway and the second entity based on a certificate belonging to the first entity. A third secure tunnel is established between the satellite terminal and the first entity based on a certificate belonging to the second entity. The contents of encrypted traffic between the first entity and the second entity are examined so that GTP acceleration may be applied to eligible traffic transmitted over the first secure tunnel.Type: GrantFiled: December 29, 2017Date of Patent: August 18, 2020Assignee: HUGHES NETWORK SYSTEMS, LLCInventors: Bhanu Durvasula, Gaguk Zakaria

Patent number: 10172032Abstract: A system and method are disclosed for admission control of mobile conversational user sessions by a satellite network is described. When a request to admit a new session over a satellite network is received, the radio access bearer setup request is transmitted to a remote terminal of the satellite network. The system determines if a requested guaranteed bit rate for the new session is available from the remote terminal. If the requested guaranteed bit rate is available, the terminal forwards the request to a gateway of the satellite network. The new session is subsequently admitted over the satellite network and allocated the requested guaranteed bit rate.Type: GrantFiled: January 20, 2017Date of Patent: January 1, 2019Assignee: HUGHES NETWORK SYSTEMS, LLCInventors: Satyajit Roy, Ramanathan Thirunallaih, Bhanu Durvasula

Patent number: 10128938Abstract: A system and method for determining hierarchical link quality metrics in a communication system, and performing different routines to optimize operation of the communication system based on the link quality metrics. Data is collected for a predetermined interval, and a carrier link quality is determined for each terminal utilizing different carriers in the communication system. A link quality is determined for each terminal type, and a beam link quality is determined for each beam in the system. Different thresholds are set so that optimization routines can be performed based on the current link quality values.Type: GrantFiled: December 29, 2016Date of Patent: November 13, 2018Assignee: HUGHES NETWORK SYSTEMS, LLCInventors: Steven Dominic Mirra, James Jehong Jong, Bhanu Durvasula

Patent number: 5870676Abstract: Methods and apparatus for monitoring problematic transmission channels in a cellular telephone system are disclosed. In the preferred embodiment, the channel monitoring method or apparatus keeps track of a defined number of calls M. After channel selection, the channel monitoring process determines whether the channel assignment was successful. The number of calls M defines the window in which the process tracks channel failures. The disclosed monitoring process can be used in either an analog embodiment or a time division multiple access (TDMA) digital embodiment having multiple channels for each frequency, such as TDMA-3. After every frequency selection, whether call assignment is successful or unsuccessful, channel information is monitored. If the monitored channel information exceeds placement thresholds, the selected frequency is placed into an alarm subpool. Preferably, the channel monitoring process has at least one alarm subpool.Type: GrantFiled: February 16, 1996Date of Patent: February 9, 1999Assignee: Hughes Electronics CorporationInventors: Bhanu Durvasula, Srikanth Yaragudipati
