The present invention discloses a communication system and a method. The communication system includes at least first 802.11 equipment and second 802.11 equipment. The first 802.11 equipment including a network connector for searching relevant information of the second 802.11 equipment and modifying a network setting of the first 802.11 equipment according to the searched relevant information, and a 802.11 driver interface. The second 802.11 equipment includes a 802.11 driver interface. The driver interface of the first 802.11 equipment communicates with the driver interface of the second 802.11 equipment in accordance with the modified network setting.

Communication systems and methods for dynamic and secure simplification of equipment networking

In a method for implementing device grouping and interactions between grouped devices a device creating a device group sends an advertisement message carrying identification information of a device group to which it belongs, to the network. After receiving the advertisement message, a network device joins the device group by the corresponding advertisement message. When two grouped network devices interact with each other, the method further comprises: sending an access request to an accessed device; judging by the accessed device whether the device sending the request is a trusted device and if so, interacting by both parties with each other; otherwise, denying the access request, or determining by the initiating device and the accessed device, a common trusted third party; acquiring by the initiating device, key information of the accessed device from the common trusted third party, and interacting with the accessed device by using the acquired key information.

This invention discloses a method of calling service among devices in home network, comprising following steps: a service calling party obtains a service handle of the called service by using the characterized information of the service, sends a service calling request information to a called party by using the obtained called service handle; the protocol stack of the called party determines whether or not the called service exists based on the service handle of the called service contained in the request information and whether or not the called service has established a renting relationship with the service calling party after receiving the request information, if not, the flow will be ended; if it is, the called party sends service call response message containing service call result to the service calling party; after receiving the service call response message, the protocol stack of the service calling patty determines whether or not the service exist based on the service handle of the called service included in the response message, and whether or not the calling service has established a renting relationship with the called party, if it is, the service calling party and the called party start the actual interacting processing of the service call; otherwise, the flow is ended. This method allows each of devices in the home network to share resources and ensure the reliability of the service call.
