  • Patent number: 10097482
    Abstract: The present application discloses methods, devices and systems for networking communication and information display. Based on a predefined layout provided by a server, service providers may customize the predefined layout by designating/designing actionable options that may be used in the layout to generate user interfaces. Due to the dual sources of the customized interfaces, some of the actionable options in different interfaces are the same and some of the actionable options are different. A user may select an actionable option displayed at a mobile terminal, which may cause the mobile terminal to send a request to the server, receive a response from the server, and display the response. The current invention allows service providers to configure predefined layouts and present the customized interfaces to users, improving communication experiences while maintaining a level of similarity between the interfaces from different service providers.

  • Patent number: 10069640
    Abstract: The current invention discloses methods and devices for adding a new member to a group, e.g. a chat group associated with a chat program. The new member may be added through a barcode-scanning process or an existing-member-invitation process. After the new member is added to the chat group, a server may send notification messages to mobile devices associated with the existing members of the group. The contents of the notification messages may vary based on the processes by which the new member is added, the number of existing members, and the direct-contact relationships the new member has with the existing members. The current invention provides simplified methods and devices for adding the new member, avoiding cumbersome operations and protecting member privacy at the same time.

  • Patent number: 10063547
    Abstract: A third-party application client performs authorization authentication with a user client and a platform server. The third party application obtains an access token and an open ID. The third-party application client interacts with the platform server for information related to the user ID by using the token, calls the user client or is called by the user client according to the open ID. The third-party application client may interact with the platform server for the information related to the user ID by using the token, so that other resources or information of the user accumulated for the platform server can be used by the third-party application client continuously.

  • Patent number: 9985683
    Abstract: Provided are a method and an apparatus for canceling interference, to resolve a problem that performance of interference cancellation is poor because accuracy of equalizer coefficients obtained by a CMTS through calculation is not sufficiently high. A specific solution is as follows: (101) A CMTS calculates L equalizer coefficients of an L-tap filter according to a preamble sequence by using an adaptive algorithm, and performs adaptive equalization on a received signal by using the L equalizer coefficients, where L is a positive integer greater than 24; and (102) the CMTS selects K equalizer coefficients from the L equalizer coefficients, and sends a ranging response message carrying the K equalizer coefficients to a cable modem CM, so that the CM performs pre-equalization on a to-be-sent signal according to the received K equalizer coefficients, where K is a positive integer less than or equal to L.
