Communication device and communication method

Abstract

The invention provides a communication device, which comprises a data processing module and a data interaction module, wherein the data processing module generates a message frame and / or analyzes a message frame which is received by the data interaction module; the message frame at least comprises a service message function identification bit; when the value of the service message function identification bit is a first value, a second value and a third value, the communication device and / or a communication device of a sending party which sends the received message frame only supports a subscription service message operation, a release service message operation, and both the subscription service message operation and the release service message operation respectively; and the data interaction module is used for sending and / or receiving the message frame. The invention further provides a corresponding communication method. According to the technical scheme of the invention, a plurality of devices can clearly know the supporting condition of service message operations, the condition that the devices which only support the subscription service message operation or the release service message operation exist in the current environment is avoided, and the improvement of efficiency of service discovery is facilitated.

Description

technical field [0001] The present invention relates to the technical field of mobile communication, in particular, to a communication device and a communication method. Background technique [0002] In WFA (Wi-Fi Alliance), a new research group NAN (Neighbor Awareness Networking, Neighbor Awareness Network) was established. Its research content is social networks, mainly how many STAs (terminals) find other STAs with common services. And for file sharing or other business. [0003] For a device that supports the NAN function (referred to as a NAN device), it may exist: it only supports the operation of publishing service messages (sending messages), only supports the operations of subscribing service messages (receiving messages), or both. However, for multiple NAN devices, if it is impossible to know the mutual support for service message operations, the following situations may occur: [0004] 1. In the NAN network, there are only NAN devices that only support subscript...

AI Technical Summary

Problems solved by technology

[0004] 1. In the NAN network, there are only NAN devices that only support subscription service messages, and these NAN devices do not understand each other's functional support, so it may happen that these NAN devices will never be able to connect to the other NAN devices. NAN devices with the same service

[0005] 2. In the NAN network, there are only NAN devices that only support publishing service messages, and these NAN devices do not know about each other’s functional support, which may cause a large number of NAN devices to publish service messages in a short period of time. A large number of conflicts are generated, which greatly reduces the connection efficiency of the device
