     DETAILED DESCRIPTION 
       [0077]    A basic thought of the disclosure is that a PN manager is configured for a PN, and the PN is managed through the configured PN manager. 
         [0078]    After the PN is established, a physical link is established between every two pieces of PN equipment in the PN, a PN server stores PN information, including a PN identifier and information such as the identifier and address of each piece of PN equipment in the PN. 
         [0079]    As shown in  FIG. 1 , a flow of making a request for becoming a PN manager by PN equipment may specifically include the following steps that: 
         [0080]    STEP  101 : PN equipment (or called equipment of a PN) transmits a manager request to a PN gateway (or called a gateway of the PN) to request to become a PN manager (or called a manager of the PN); 
         [0081]    here, the manager request may include the identifier of the PN and the identifier of the PN equipment; 
         [0082]    STEP  102 : the PN gateway forwards the manager request to a PN server (or called a server of the PN); 
         [0083]    STEP  103 : the PN server receives the manager request, judges whether the PN equipment can be the PN manager or not; if the PN equipment can be the PN manager, then the PN server sets the PN equipment as the PN manager, adds the information of the PN equipment into related PN manager information, and continues to execute STEP  104 , otherwise directly executes STEP  104 ; 
         [0084]    here, the PN server may judge whether the PN equipment can be the PN manager or not by judging whether the PN equipment has a sufficient UI or not, and/or judging whether the PN equipment has a sufficient equipment capability or not and the like; specifically, the UI and/or the equipment capability required if any PN equipment wants to be a PN manager are/is preconfigured on the PN server, and then the PN server can acquire the UI and/or equipment capability of the PN equipment after receiving the manager request, judges whether the UI and/or equipment capability of the PN equipment are/is consistent with the preconfigured UI and/or equipment capability required by the PN manager or not, determines that the PN equipment can be the PN manager if the UI and/or equipment capability of the PN equipment are/is consistent with the preconfigured UI and/or equipment capability required by the PN manager, and if not, determines that the PN equipment cannot be the PN manager; 
         [0085]    STEP  104 : the PN server returns a response to the PN gateway, wherein the response includes information indicating whether the manager request is successful or not; 
         [0086]    here, if the PN server determines that the PN equipment can be the PN manager of the PN, and the PN information has been updated, then the response includes manager request success information; otherwise the response includes manager request failure information; 
         [0087]    STEP  105 : the PN gateway forwards the response to the PN equipment; and 
         [0088]    STEP  106 : if the response includes the manager request success information, then the PN gateway further transmits a notice to other PN equipment belonging to the PN to notify the other PN equipment of the identifier of the PN manager. 
         [0089]    Here, the notice includes the identifier of the PN manager; the other PN equipment of the PN receives the notice, and updates its own stored corresponding PN information. 
         [0090]    Here, if the response includes the manager request failure information, STEP  106  is then eliminated. 
         [0091]    After the PN equipment becomes the PN manager, a request for deleting the PN manager may also be made, and as shown in  FIG. 2 , the process may specifically include the following steps that: 
         [0092]    STEP  201 : the PN equipment serving as the PN manager transmits a manager deletion request to the PN gateway to request to delete the PN manager; 
         [0093]    here, the manager deletion request includes the identifier of the PN and the identifier of the PN equipment; 
         [0094]    STEP  202 : the PN gateway forwards the manager deletion request to the PN server; 
         [0095]    STEP  203 : the PN server receives the manager deletion request, deletes the PN manager, and deletes the equipment information of the PN manager from PN manager information; 
         [0096]    specifically, information about the PN manager is deleted from the PN information, for example, the identifier and the like of the PN manager are deleted; 
         [0097]    STEP  204 : the PN server returns a response to the PN gateway; 
         [0098]    STEP  205 : the PN gateway forwards the response to the PN equipment; and 
         [0099]    STEP  206 : the PN gateway transmits a notice to the other PN equipment belonging to the PN to notify the other PN equipment that the PN manager has been deleted. 
         [0100]    Here, the notice includes the identifier of the PN manager; the other PN equipment of the PN receives the notice, and deletes the equipment information of the PN manager from the PN information stored by the other PN equipment. For example, the identifier and the like of the PN manager are deleted from the locally stored PN information. 
         [0101]    If there has been a PN manager in the PN, other PN equipment in the PN may make requests for becoming managed PN equipment to be managed by the PN manager. 
         [0102]    For example, PN equipment  1  and  2  belong to the same PN, the PN equipment  1  is a PN manager, and the PN equipment  2  may make a request for becoming a managed PN equipment. As shown in  FIG. 3 , a specific implementation flow may include the following steps that: 
         [0103]    STEP  301 : the PN equipment  1  serving as the PN manager transmits a managed PN equipment addition request to the PN gateway to request to add the PN equipment  2  as a managed PN equipment; 
         [0104]    here, the managed PN equipment addition request includes the identifier of the PN and the identifier of the PN equipment  2 ; 
         [0105]    STEP  302 : the PN gateway forwards the managed PN equipment addition request to the PN server; 
         [0106]    STEP  303 : the PN server receives the managed PN equipment addition request, and adds the PN equipment  2  as a managed PN equipment, that is, the equipment information (such as the identifier) of the PN equipment  2  is added into the managed PN equipment information of the PN; 
         [0107]    STEP  304 : the PN server returns a response to the PN gateway; 
         [0108]    STEP  305 : the PN gateway forwards the response to the PN equipment  1 ; and 
         [0109]    STEP  306 : the PN gateway transmits a notice to the PN equipment  2  to notify the PN equipment  2  that it has become the managed PN equipment. 
         [0110]    If there has been a PN manager and managed PN equipment in the PN, the PN equipment serving as the PN manager may also delete the managed PN equipment. 
         [0111]    For example, PN equipment  1  and  3  belong to the same PN, the PN equipment  1  is the PN manager, the PN equipment  3  is a managed PN equipment, and as shown in  FIG. 4 , a specific implementation flow of deleting the PN equipment  3  by the PN equipment  1  may include the following steps that: 
         [0112]    STEP  401 : the PN equipment  1  transmits a managed PN equipment deletion request to the PN gateway to request to delete the PN equipment  3  from the managed PN equipment; 
         [0113]    here, the managed PN equipment deletion request may include the identifier of the PN and the identifier of the PN equipment  3 ; 
         [0114]    STEP  402 : the PN gateway forwards the managed PN equipment deletion request to the PN server; 
         [0115]    STEP  403 : the PN server receives the managed PN equipment deletion request, and deletes the PN equipment  3  from the managed PN equipment, that is, the information (such as the identifier) of the PN equipment  3  is deleted from related information of managed PN equipment; 
         [0116]    STEP  404 : the PN server returns a response to the PN gateway; 
         [0117]    STEP  405 : the PN gateway forwards the response to the PN equipment  1 ; and 
         [0118]    STEP  406 : the PN gateway transmits a notice to the PN equipment  3  to notify the PN equipment  3  that it has been deleted from the managed PN equipment. 
         [0119]    If there has been a PN manager and managed PN equipment in the PN, the PN equipment serving as the PN manager may also manage the managed PN equipment. 
         [0120]    For example, PN equipment  1  and  4  belong to the same PN, the PN equipment is the PN manager, the PN equipment  4  is a managed PN equipment, and as shown in  FIG. 5 , a specific implementation flow of managing the PN equipment  4  by the PN equipment  1  may include the following steps that: 
         [0121]    STEP  501 : the PN equipment  1  transmits a management request for managing the PN equipment  4  to the PN gateway; 
         [0122]    here, the management request may include the identifier of the PN and the non-updated equipment information and updated equipment information of the PN equipment  4 ; 
         [0123]    during practical application, the non-updated equipment information of the PN equipment  4  may be information such as a non-updated identifier of the PN equipment  4 , and the updated equipment information of the PN equipment  4  may be information such as an updated identifier of the PN equipment  4 ; 
         [0124]    STEP  502 : the PN gateway receives the management request, and transmits an updating request for updating the equipment information of the PN equipment  4  to the PN server; 
         [0125]    here, the updating request may include the identifier of the PN and the non-updated equipment information and updated equipment information of the PN equipment  4 ; 
         [0126]    STEP  503 : the PN server receives the updating request, updates the equipment information of the PN equipment  4  in the PN information, and returns a response to the PN gateway; 
         [0127]    that is, the PN server receives the updating request, and modifies the equipment information of the PN equipment  4  in the PN information into the updated equipment information of the PN equipment  4  in the updating request; 
         [0128]    STEP  504 : the PN gateway transmits an updating request to the PN equipment  4  to notify the PN equipment  4  to update its equipment information; 
         [0129]    here, the updating request may include the non-updated equipment information and updated equipment information of the PN equipment  4 ; 
         [0130]    STEP  505 : the PN equipment  4  receives the updating request, updates its own equipment information and returns a response to the PN gateway; 
         [0131]    that is, the PN equipment  4  receives the updating request, and modifies its own equipment information into the updated equipment information of the PN equipment  4  in the updating request; 
         [0132]    STEP  506 : the PN gateway returns the response to the PN equipment  1 ; and 
         [0133]    STEP  507 : the PN gateway transmits a notice to other PN equipment of the PN to notify the other PN equipment of the updated equipment information of the PN equipment  4 . 
         [0134]    During practical application, there may be one manager and one or more pieces of managed equipment in one PN. Generally, one manager and one or more pieces of managed equipment may be set for one PN. One piece of PN equipment in the PN may serve as the manager or the managed equipment of the PN. The PN server stores PN information, and the PN information may include the identifier of the PN, the equipment information of each piece of PN equipment in the PN, the equipment information of the PN manager and the equipment information of the managed PN equipment. The PN gateway and the PN equipment may also store the information of the PN to which they belong. 
         [0135]    Correspondingly, the disclosure also provides a PN system, which includes PN equipment which is set as a PN manager, wherein the PN equipment which is set as the PN manager is configured to execute management over a PN. 
         [0136]    The PN system further includes a PN server and a PN gateway; the PN equipment is configured to transmit a manager request including the identifier of the PN equipment and a PN identifier to the PN gateway; the PN gateway is configured to forward the manager request to the PN server, and when the PN server returns a response including manager request success information, transmit a notice to other PN equipment belonging to the current PN to notify the other PN equipment of the identifier of the PN manager; and the PN server is configured to receive the manager request, set the PN equipment as the PN manager when determining that the PN equipment can be the PN manager, and return the response to the PN gateway, the response including the manager request success information.
