Patent number: 10944664Abstract: A base station provides, a first number of probe packets to an access point for transmission to a user equipment over an access network path. The base station receives information indicating a bandwidth of the access network path estimated by the user equipment. The base station determines which of the base station or the access point to use for communication with the user equipment based on the bandwidth. The user equipment receives a second number of packets over an air interface and determines inter-arrival packet delays for the second number of probe packets. The user equipment estimates the bandwidth of the air interface based on the inter-arrival packet delays, the first number, and a time interval for transmission of the first number of probe packets. The user equipment transmits information indicating the bandwidth.Type: GrantFiled: September 1, 2016Date of Patent: March 9, 2021Assignees: Nokia of America Corporation, Alcatel LucentInventors: Jonathan Ling, David Lopez-Perez, Bongho Kim, Vasudevan Subramanian, Satish Kanugovi

Patent number: 10412624Abstract: A method includes receiving at least one current network condition factor (NCF), each current NCF indicating a level of congestion of a corresponding network. The method determines that there is an autonomous report to be transmitted and in response determines a policy entry of a policy used for autonomous reporting based on matching values of one or more input parameters related to the autonomous report to values of one or more input parameters of the policy entry. A reference NCF for a first network is determined from the corresponding policy entry. The method then determines whether to request to transmit the autonomous report on the first network based on a comparison of the reference NCF for the first network and the current NCF of the first network.Type: GrantFiled: May 3, 2017Date of Patent: September 10, 2019Assignees: Alcatel Lucent, Nokia of America CorporationInventors: Subhasis Laha, Padmavathi Sudarsan, Vasudevan Subramanian, Krishna Pramod Adharapurapu, Satish Kanugovi

Patent number: 10212631Abstract: A radio access network element includes a cellular interface and a processor. The cellular interface is configured to communicate with the user equipment via a cellular link. The processor is configured execute computer readable instructions to cause the radio access network element to: transmit a plurality of probe packets to the user equipment via an IP tunnel between the radio access network element and the user equipment through a wireless local area network access point; receive a probe packet response from the user equipment, the probe packet response being indicative of a connection quality of the IP tunnel between the radio access network element and the user equipment; and determine whether to switch from a first traffic routing mode to a second traffic routing mode based on the probe packet response from the user equipment.Type: GrantFiled: November 11, 2015Date of Patent: February 19, 2019Assignee: Nokia of America CorporationInventors: Jonathan Ling, David Lopez-Perez, Bong Ho Kim, Doru Calin, Vasudevan Subramanian

Patent number: 10142965Abstract: In a method for providing application services to a user in a communications network, a first multi-path transport control protocol (MPTCP) flow is mapped to a first evolved packet system (EPS) bearer associated with a first serving base station for the user, and a second MPTCP flow is mapped to a second EPS bearer associated with a second serving base station for the user. The first MPTCP flow is output on the first EPS bearer for delivery to the user through the first serving base station, and the second MPTCP flow is output on the second EPS bearer for delivery to the user through the second serving base station. Each of the first and second MPTCP flows correspond to a same multipath transport control protocol MPTCP connection for an application.Type: GrantFiled: September 30, 2014Date of Patent: November 27, 2018Assignee: Alcatel LucentInventors: Satish Kanugovi, Vasudevan Subramanian, Alistair Urie
