Abstract:
An indication map delivery method, an indication operation method, a device, and a system are provided. In the embodiments of the present invention, a compressed Indication Map (IM) generated by a wireless access device includes at least one of a tiny partial bitmap sub-element, a skipped indication bits sub-element, and an indication bit offset sub-element, and consecutive indication bits with the same value at positions in an original IM can be compressed into a skipped indication bits sub-element, an indication bit offset sub-element, or the like. The technical solutions of the embodiments of the present invention facilitate improvement of compression efficiency of an IM, and further reduce radio air interface resources occupied for sending the IM and improve IM sending efficiency.
Abstract:
A method, a device and a system for enabling a routing function and transmitting data, which relate to the field of communications, and are capable of sharing a single session task through a plurality of access points, thereby ensuring data transmission quality. When a station uses an external network identifiable address, and performs data transmission of a single session task through a first access point, an address of a club routing function (CR) router connected to the first access point is determined; at least one second access point connected to the same CR router with the first access point is determined.
Abstract:
A method, apparatus and system for software management are provided that relate to the technical field of communications, and that allow software installed on a Universal Plug and Play (UPnP) device by a service provider to be managed only by that service provider. The method comprises receiving a software installation command sent by a first control device, installing software according to the software installation command and storing a first authentication information required during management of the software; receiving a software management command sent by a second control device, and acquiring a second authentication information corresponding to the software management command, which command is used in managing the software; when the second authentication information is consistent with the first authentication information, executing the software management command.
Abstract:
A method for anchor master selection includes: a device receives a NAN Beacon frame, where the NAN Beacon frame carries first AM information and first TSF information, and the first AM information includes: a first AMR, a first HC, and a first AMBTT; if the NAN Beacon frame is used for AM selection, when the first AMR is less than a second AMR and an MR of the device is greater than the first AMR, switching a role of the device to AM, where second AM information recorded in the device includes: the second AMR, a second HC, and a second AMBTT; and if the NAN Beacon frame is used for AM selection, when the first AMR is less than the second AMR, and the MR of the device is less than the first AMR, updating the second AM information and second TSF information according to the NAN Beacon frame.

Abstract:
A video coding method, a video decoding method, a video coder, and a video decoder are disclosed herein. A video coding method includes: performing base-layer coding for the first view, and extracting prediction information of at least one layer by combining a locally decoded first view and a second view; performing enhancement-layer coding for prediction information of at least one layer respectively; and multiplexing the enhancement-layer codes and the base-layer codes of the first view to obtain encoded information. Through the embodiments of the present disclosure, the contents of the 3D video are encoded hierarchically, and various 3D display devices connected in different networks can display the 3D video hierarchically.
Abstract:
Embodiments of the present invention disclose a method, an apparatus, and a system for pushing information based on a wireless local area network. The method includes: generating a push information indication message, where the push information indication message includes index information of one or more pieces of push information, where the index information includes at least one of a sequence number, an information digest, a category number, and a category name of the push information; broadcasting the push information indication message; and sending the push information. With the present invention, information may be pushed on wireless local area networks that are widely used at present, such as a WiFi network. Especially, in places such as scenic spots, shopping malls, and exhibition halls, WiFi networks can be used to introduce related information to users, instead of making explanations or presentations manually.
Abstract:
A service query method includes: when receiving first service query request messages sent by multiple access points, where the first service query request message includes a station identity and requested service information, a service node sends query result information to only one or more access points thereof, namely a first access point, so as to send the query result information to a station corresponding to the station identity, and sends instruction information to another access point to instruct the another access point not to send the query result information.
Abstract:
A file transfer method includes: sending, by a sending device, a ready request message to a multicast group in a multicast manner; when receiving a first ready message returned by a first device in the multicast group, sending, by the sending device, a master receiving device determining message to the first device, where the master receiving device determining message is used to notify the first device that the first device has been selected as a master receiving device, and sending a data packet of a to-be-sent file to the multicast group in a multicast manner; and when a second device newly joins the multicast group, sending a first message to the second device to notify it in time of information about a file that is currently being transferred, so that the newly joined device can start receiving immediately.
