BEST MODE FOR CARRYING OUT THE INVENTION Hereinafter, the present invention will be described in detail with reference to the accompanying drawings. It should be noted that the embodiments in the present application and the features in the embodiments may be combined with each other without conflict. When the personal network element in the embodiment of the present invention switches the working mode to the gateway state, it needs to function as a personal network gateway, so the requirements for capabilities are relatively high, especially for hardware capabilities, communication capabilities, etc., so not each The personal network element has the ability to work in the state of the gateway. The embodiment of the present invention uses the mode switching request message request to carry the switching capability request information, so that the personal network element can determine whether it meets the gateway running requirement. Embodiment 1 FIG. 1 is a flowchart showing a working mode switching method of a personal network element according to an embodiment of the present invention. The method includes the following steps: Step S102: A personal network element receives a mode switching request message. The mode switching request message carries the switching capability requirement information of the personal network gateway mode; the mode switching request message received by the personal network element may be sent by the gateway of the personal network, or may be sent by the personal network server, and may also be It is triggered by its own needs. Step S104: The personal network element determines whether the switching setting information of the personal network matches the switching capability requirement information, and if yes, sends a mode switching response message to the upper-level network element. After receiving the mode switch response message, the upper-level network element can complete the mode switching process according to the existing process. The switching setting information of the personal network element itself includes the set device capability information, such as the communication capability, the audio and video capability, the hardware capability, the software capability, the operating system capability, and the like; and the switching setting information may further include the set user preference information. Such as whether it can be used as a gateway information. Based on this, whether the personal network element determines whether the handover setting information and the handover capability requirement information match the following: the personal network element determines whether the set device capability information and the handover capability requirement information match. Alternatively, the personal network element determines whether the set device capability information and the user preference information match the handover capability request information. When the switching setting information includes both device capability information and user preference information, the present invention The embodiment preferentially selects the latter manner to determine whether the switching setting information and the switching capability request information are self-contained. When the personal network element determines that the handover setting information does not match the handover capability requirement information, no response processing is performed to reduce traffic in the network. A plurality of network elements that meet the above-mentioned handover capability requirement information may exist in the personal network. In order to enable the upper-level network element to select one of the most capable network elements from the plurality of network elements that meet the requirements as the personal network gateway, the present invention The embodiment preferably further includes, in the foregoing sending mode switching response message, the capability information of the personal network element (the capability information may be the device capability information that is set by using the device capability information). After the mode switching response message is sent to the network element, the method further includes: The upper-level network element receives a mode switch response message from one or more personal network elements, and determines the network element to perform handover according to the capability information in the mode switch response message, and sends an allow handover message to the determined network element; After the determined network element receives the permission to switch message, it performs work mode switching. As an implementation manner, the mode switching response message may not carry the capability information of the personal network element. In this case, the upper-level network element may select one network element from the personal network element that sends the mode switching response message. For example, according to a certain rule, the selected network element is determined as the network element for performing handover, and only the allowed handover message is sent to the network element, and the rejection handover message is sent to other personal network elements that send the handover response message. After the determined network element receives the permission to switch message, the working mode switching includes: after the determined network element receives the allowed handover message, enters the handover state, and sends the handover state notification message to the upper-level network element; the determined network element After switching to the personal network gateway mode, the upper-level network element sends an incoming handover complete message, and runs according to the personal network gateway mode. Preferably, before the PN network element receives the mode switching request message, the method further includes: sending, by the upper-level network element, the mode switching request message in a multicast or broadcast manner in the personal network. The upper-level network element is a gateway or a server of the personal network. The personal network element in the related art responds to the received mode switching request message, and whether the responding network element has the gateway capability is determined by the upper-level network element (personal network server), so the required signaling interaction is required. The number of times is relatively large, resulting in large network traffic. In this embodiment, the personal network element determines whether to respond to the mode switching request message, and only responds when the switching capability requirement is met, so The network traffic and consumption are reduced, and the problem of low efficiency of working mode switching of the personal network element is solved. At the same time, the handover method of this embodiment is mainly solved within the personal network, and the security of the network is also ensured. Embodiment 2 Before performing the mode switching, the devices in the network need to be configured. For example: the personal network element completes the capability matching setting, the personal preference setting, the device capability setting, the personal gateway gateway and the personal network server complete the gateway capability matching setting, and these settings can be performed in advance by the network management. According to the actual communication situation of the network, a device in the network can initiate a mode switching request message. The device that initiates the mode switching request message may be a personal network gateway, for example: when the gateway determines that it needs to leave the personal network network, or determines that its capability no longer satisfies the capability requirement of the network, the gateway may initiate a mode switching request message; The device that switches the request message may also be a personal network server. For example, when the server detects the traffic information and considers that the health status of the current network is faulty, the mode switching request information may be initiated. The device that initiates the mode switching request message may also be a personal network. A certain network device (ie, a network element), for example: When a network device in the personal network expects a gateway to improve communication capability, a mode switching request message may also be initiated. If the mode switching request is initiated by the personal network device, the embodiment of the present invention considers that the personal network device receives the mode switching request message processing. FIG. 2 is a flowchart of a working mode switching method of a personal network element according to an embodiment of the present invention. The method includes the following steps: Step S202: After receiving the mode switching request message, the personal network element reads The switching capability request information in the mode switching request message is obtained. Step S204, the personal network element acquires the set user preference information and the device capability information, and determines whether the matching is matched by comparing with the switching capability request information. Step S206, the personal network If the device determines that the device meets the capability requirement and the user preference information allows, the mode switch response message is sent to the gateway. Step S208: The gateway receives a mode switch response message of one or more personal network elements, and the gateway according to the actual situation of the network and each device The capability status determines the network element that performs the handover, makes a response to the permission or rejection of each network element, and sends a corresponding permission handover message or rejects the handover message; In this embodiment, the gateway receives the mode switching response as an example. If necessary, the personal network element may also send the mode switching response message to the server, and the server determines the network element to perform the handover. In this embodiment, the foregoing personal network element receives the permission to switch message as an example for description. Step S210, the personal network element receives the permission to switch message, enters a mode switching state, and sends a handover state notification message to the gateway, the server, and other network devices; if the personal network element receives the rejection handover message, the original work is maintained. The mode is unchanged; the personal network element performs mode switching, including but not limited to the corresponding authentication and authentication process and establishing a connection with the server. Step S212: After completing the handover, the personal network element sends a handover complete message to the gateway, the server, and other network devices, and returns from the handover state to the normal state, and assumes the mode network requirement after the handover. A schematic diagram of a state machine when the network element is switched as shown in FIG. 3, wherein a black circle on the left side indicates that the network element is in an initial state, and a black circle below indicates that the network element is in an end state. The network element receives the mode switching request message in the normal state and enters the capability matching state. If the matching succeeds, the mode switch state is entered. If the matching fails, the mode returns to the normal state. After the switching state is successful, the mode enters the new mode state, and then The new mode is running, that is, it enters the normal state. In this embodiment, a large number of messages of mode switching are transmitted inside the personal network, which simplifies the communication relationship between the personal network network and the personal network server, reduces the load outside the network, and determines whether the personal network element satisfies the handover capability. Requirements, the implementation is relatively simple, the interaction between the devices is less, and the switching efficiency is very high.
