Patent number: 10536854Abstract: In order to facilitate access to multiple networks, an electronic device may first authorize a portable electronic device to access a radio-access network associated with a network operator. In particular, the electronic device may provide a request with a first identifier for a portable electronic device to an authentication/authorization server for access to the radio-access network. After receiving first authorization information from the authentication/authorization server for the portable electronic device to access the radio-access network, the electronic device may provide a second request with a second identifier of the portable electronic device to a second server for access to a second network associated with the second server and an entity. Based on the subsequent response from the second server, the electronic device may provide access information to a radio node that allows the portable electronic device to access the radio-access network, or radio-access network and the second network.Type: GrantFiled: March 8, 2017Date of Patent: January 14, 2020Assignee: Arris Enterprises, LLCInventors: David S.

Patent number: 10237756Abstract: In one embodiment, a neighbor access point list is obtained. Statistics are maintained for a current access point that a client is currently associated with, including previous access points previous clients have roamed from prior to associating with the current access point, and next access points the previous clients associated with. The neighbor access point list for the client is optimized, by determining one or more previous clients that associated with a same previous access point as the client and prioritizing access points in the optimized neighbor access point list, based on the next access points the one or more previous clients associated with. The optimized neighbor access point list is sent to the client.Type: GrantFiled: January 21, 2016Date of Patent: March 19, 2019Assignee: Cisco Technology, Inc.Inventors: Tak Ming Francis Pang, David S.
