Incoming network; the physical entity node is a node device with automatic deployment function implemented based on an existing terminal device.

[46] As shown in FIG. 1 , the network device plane formed by the self-service nodes is called a self-service plane, and on the self-service plane, the power adjustment of each self-service node through each node wireless signal and the use of an omnidirectional antenna/directional antenna , forming a wireless access network based on the support of the node capability and targeting the full coverage of the wireless signal, providing a broadband wireless access service for the terminal node (ie, the user terminal) within the coverage of the wireless signal, the terminal node including the self-service node And non-self-service nodes.

[47] Specifically, the self-deployed wireless broadband access network includes a terminal device having a wireless communication capability and a computing processing capability for performing a communication service, and the terminal having the wireless transceiver capability and the calculation processing capability for performing the communication service The equipment includes the following:

The terminal node provides a broadband wireless access service (that is, the gateway node and the network node are both provided with a wireless interface for information interaction with the terminal node), so that the terminal node can communicate with the external network through the gateway node and the network node.

[52] The specific implementation structure of each type of terminal described above will be described below.

[61] The forwarding service processing unit 240 is configured to perform information transmission processing by the wireless transceiver 200 in an information delivery network to which the network processing unit 230 joins, that is, to use with an adjacent gateway node or a network node. Interacting information between;

[62] The access service processing unit 250 is configured to perform information interaction processing with the terminal node through the wireless transceiver 200 in a wireless manner, so as to provide an access service for the terminal node.

[63] It should be noted that the network processing unit 230 may specifically include a signal detecting unit and a registration processing unit, where the signal detecting unit is configured to detect a wireless signal of an adjacent terminal device, and The registration processing unit is triggered after detecting the wireless signal of the adjacent terminal device; the registration processing unit is configured to perform a registration operation on the adjacent terminal device, and join the information delivery network where the adjacent terminal device is located;

The gateway node or the network node performs management, where the neighboring device management unit is configured to manage the process of joining or leaving the network of the adjacent terminal device, including when the adjacent terminal device joins the network Performing authentication and registration processing, performing topology update processing, etc., deleting the registered information and performing topology update processing, etc. after leaving the network; the access authority management unit is configured to connect the terminal node requesting access Incoming access control management, that is, controlling whether the corresponding terminal node is allowed to access the network.

[66] (2) Network node

[67] The difference between the network node device and the gateway node device is that the network node does not have the function of connecting with the wired network, that is, the network node can also serve as a user of the wireless access network service or as a wireless connection. A component node of the network can specifically provide a forwarding function of the data stream; meanwhile, it can also provide an access service function of the terminal node;

[68] Similarly, the network node can also be a consumer electronic device with corresponding capabilities such as a PC, a portable computer device, or a mobile terminal device (such as a PDA, a palmtop device, a mobile phone, or a smart phone).

[69] The specific implementation structure of the network node is as shown in FIG. 3, including a wireless transceiver 300 and a general service processing unit 310, and an access service processing unit 350, a forwarding service processing unit 340, and a network processing unit 330. The functions implemented and their functions are substantially the same as those of the corresponding units in the gateway node, and will not be described in detail herein.

[70] Moreover, the network node may also serve as the management node, that is, the network processing unit 330 may further include at least one of a neighboring device management unit and an access rights management unit, for joining or leaving the network. The other gateway nodes or network nodes perform management operations, and are used to perform access authority control management on the terminal nodes requesting access. [71] (3) Terminal node

[72] The terminal node (ie, the terminal device) is a user serving a pure wireless access network, and the terminal node can be a PC, a portable computer device or a mobile terminal device (such as a PDA, a palmtop device, a mobile phone or a smart phone, etc.) ) etc. have devices that use wireless broadband access services;

[73] The specific implementation structure of the terminal node is as shown in FIG. 4, and includes a wireless transceiver 400 and a general service processing unit 410. The corresponding functions are basically the same as those of the previously described gateway nodes and corresponding units in the network node.

[74] Through the information interaction between the gateway node and the network node, a self-service wireless access service network that can provide wireless access services for the terminal node can be self-serviced.

[75] The structure of the self-service mode wireless access service network may be as shown in FIG. 5, wherein the gateway node and the network node in the self-service mode are self-services implemented by terminal devices having predetermined processing functions in the network, respectively. The gateway node and the self-service network node, the corresponding gateway node (ie, the self-service gateway node) and the network node (ie, the self-service network node) form a corresponding self-service plane, and the gateway node in the self-service plane is connected to the wired network and performs information interaction. . The self-service plane can provide a broadband wireless access service for the terminal node, that is, the wireless signal interaction between the terminal node and the self-service plane node, and wireless broadband access through the self-service plane.

[76] It can be seen that the wireless access network through the self-service mode shown in Fig. 5 can provide a complete wireless coverage service for the area where the service is desired to be obtained.

[77] On the basis of the self-service mode wireless access service network, in order to further expand the coverage of the corresponding wireless access service or improve the wireless service quality (such as railways, highways, etc.) for special areas, manual The corresponding gateway node and the network node are deployed, that is, the corresponding deployment plane network is established through the corresponding gateway node and the network node, thereby providing the corresponding broadband access service for the terminal node.

[78] As shown in FIG. 6, a network device plane composed of a gateway node and a network node, that is, a deployment gateway node and a deployment network node, is called a deployment plane, and can be obtained by manually setting a gateway node and deploying a network node. Good wireless coverage signals and access service quality, thus providing better services for user terminals such as terminal nodes.

[79] In the deployment plane shown in FIG. 6, each node constitutes a network of a full-area wireless coverage by adjusting the position of each node, adjusting the power of the node wireless signal, and using the omnidirectional antenna/directional antenna. The terminal nodes under the domain provide broadband wireless access services, such as providing broadband wireless access services in the terminal phase in areas other than self-service plane signal coverage and high-speed mobile terminals along the road.

[80] According to the different setting relationship between the self-service plane and the deployment plane, the broadband wireless access service network jointly constructed by the self-service plane and the deployment plane may specifically include a superposition mode, a fusion mode, and a hybrid mode, where: the superposition mode refers to The self-service plane and the deployment plane are independent of each other and are superimposed. The fusion mode refers to that the self-service plane and the coverage area of the deployment plane are complementary to each other to form a coverage area; the hybrid mode, that is, the overlay and the fusion The mode refers to the setting of the self-service plane and the deployment plane by using the overlay mode and the merge mode.

[81] In various modes, the process of providing a radio access service for a terminal node includes: in a uplink direction, after receiving, by a terminal device as a gateway node, a terminal device or a terminal node that is a network node transmits information wirelessly Sending to the wired network in a wired manner; in the downlink direction, the terminal device as the gateway node receives the information of the wired network, and sends the information to the terminal node wirelessly through the terminal device as the network node or directly to the terminal wirelessly node. It should be noted that the gateway node or the network node may also serve as the terminal node. Therefore, the gateway node or the network node is only a corresponding user terminal for a certain service.

[82] The specific implementation of these three modes and the way in which the terminal nodes implement broadband wireless access will be described below.

[83] (-) Overlay mode

[84] As shown in FIG. 7, the overlay mode refers to a superposition mode in which the self-service plane and the deployment plane wirelessly cover the same expected service area, and specifically, each node on the self-service plane and the deployment plane forms a full coverage area. Try to form a fully covered broadband wireless access network.

[85] When the terminal node receives the wireless signals of two planes in the same time, it selects a plane according to a certain rule to perform wireless broadband access, so as to carry out corresponding services, for example, the corresponding selection information may be selected according to preset information. The plane, or the selection of the access plane according to the different wireless signal qualities of the two planes, etc.; when the terminal node receives only one plane of the wireless signal, the wireless broadband access is unconditionally passed through the plane.

[86] (ii) Convergence model [87] As shown in Figure 8, the convergence mode refers to the convergence mode of the wireless coverage mode of the same desired service area between the self-service plane and the deployment plane. That is, the nodes on the self-service plane and the deployment plane work together to form a complete Covered broadband wireless access network, the nodes on the two planes need to consider the coverage and topological relationship formed by the nodes of the plane in forming the full coverage area, and also need to consider the coverage of the nodes of the other plane. The impact of topology.

[88] In this mode, the terminal node will only receive a flat wireless signal, and will use the plane for wireless broadband access, that is, through the plane to carry out the corresponding services.

[89] (iii) Mixed mode

[90] As shown in Figure 9, the hybrid mode refers to the wireless coverage mode of the same desired service area between the self-service plane and the deployment plane, which is the same as the overlay mode and the fusion mode, that is, the overlay mode and the fusion mode exist. The nodes on the self-service plane and the deployment plane form a full coverage area, taking into account not only the coverage and topological relationship formed by the nodes of the plane, but also the impact of the nodes of another plane on its coverage and topology if needed; For example, in some areas, the two planes try to form a full coverage broadband wireless access network. In some areas, two planes need to cooperate with each other, and the nodes on different planes try to form a whole in the same position. Covered broadband wireless access network.

[91] When the terminal node receives two plane radio signals, it selects a plane to perform wireless broadband access according to certain rules. When the terminal node receives only one plane wireless signal, the plane is used unconditionally. Conduct wireless broadband access.

[92] In order to facilitate the understanding of the embodiments of the present invention, the process of constructing a corresponding radio access network in the embodiment of the present invention will be described below with reference to the accompanying drawings.

[93] In the process of constructing the wireless access network, when a terminal device can be used as a gateway node (for example, a PC, a portable computer device, or a mobile terminal device (such as a PDA, a palmtop device, a mobile phone, a smart phone, etc.), etc. } After booting and accessing the network in a wired manner, the wireless transceiver in the terminal device can listen to the current radio environment, and according to the listening result, prompt the user of the terminal device to agree to join the mutual help wireless in the manner of the gateway node. In the broadband network, if it agrees, the terminal device will become a gateway node in the network, and the peers of the network such as the Internet can also forward data for other nodes, thereby providing corresponding network access services for other nodes. . Therefore, a fully covered wireless broadband access network is voluntarily established to meet the needs of users' free exchange of information. [94] In the process of constructing the radio access network, the process of the terminal device joining the self-service plane is as shown in FIG. 10, and specifically includes the following steps:

[95] Step 101: The terminal device is powered on, and the corresponding process of joining the wireless access network is performed;

[96] Step 102: The wireless transceiver in the terminal device senses the surrounding wireless environment, that is, perceives surrounding neighbor nodes (adjacent terminal devices);

[97] Step 103: The terminal device performs information exchange with the sensed neighbor node, for example, sending a join request to the neighboring node, so that the terminal (such as the management node) performs authentication and authorization on the terminal device;

[98] The terminal device may be authenticated and authorized by the neighboring node (adjacent gateway node or network node) or the designated node device as a corresponding management node, where the management node responsible for authentication and authorization may It can be a gateway node, or it can be a network node, or it can be other devices specially used for authentication and authorization processing.

[99] Step 104: The management node determines whether the authentication and the authorization are passed. If not, the terminal device is prohibited from joining the network, and the process ends. If yes, proceed to step 105;

[100] Step 105: The terminal device reports its capability parameter to the neighboring node (for example, may include the maximum transmit power of the wireless device, the orientation capability of the antenna, the power adjustment capability, and the frequency selection capability)

, forwarding capabilities, power lasting capabilities, CPU processing power, etc.);

[101] Step 106: Determine whether the terminal device can be added to the broadband wireless access network as a gateway node or a network node, for example, the neighboring node negotiates with the network to determine whether the joined terminal device is capable, willing, and necessary. Join the broadband wireless access network in the form of a network node or a gateway node; if yes, go to step 107, otherwise, notify the joining terminal device to join in the terminal node manner, and end the joining processing flow;

[102] Step 107: The neighbor node negotiates with the network according to various parameters after the terminal device joins (for example, may include a topology relationship between nodes of the network, a capability parameter of each node of the network, and a logical area division of each node of the network, The network provides the traffic model of the service, and so on.) Generates a new network topology map, and sends the parameters (for example, the topology relationship between the nodes of the network, the direction/power/frequency of the wireless signal transmission of the device, etc.) Giving the terminal device and the network node or gateway node that needs to perform parameter adjustment, so that each node device performs wireless coverage and topology reconfiguration, and route recalculation, etc. [103] Step 108: The terminal device joins the broadband wireless access network in the manner of a network node or a gateway node, so that the broadband wireless access service can be provided for other node devices.

[104] On the self-service plane, the main process of maintaining the network on the network node or gateway node is as shown in Figure 11, which specifically includes the following steps:

[105] Step 111: The handshake information is exchanged between adjacent network nodes or gateway nodes;

[106] Step 112: The network node or the gateway node as the management node determines whether it is over, if not, then continue to step 111, otherwise, go to step 113;

[107] The step is specifically determining whether to receive the handshake information of the neighboring network node or the gateway node, and if not, the corresponding timer is exceeded;

[108] Step 113: Reconfigure the broadband wireless access network and update the corresponding topology;

[109] Specifically: the network node or the gateway node does not receive the handshake information of a network node or a gateway node within a predetermined time interval, and then considers that a network node or a gateway node has failed or the mobile has left the network, and the adjacent network The node or gateway node will negotiate with the network to recalculate a new network topology map according to various parameters, and send the parameters of the new network topology to the network node or gateway node that needs to be adjusted, so as to facilitate wireless coverage and Topology reconfiguration;

[110] Step 114: Under the new network topology condition, the network node or the gateway node performs recalculation of the route, and provides a corresponding broadband access service according to the calculation result;

[111] Step 115: Perform cleanup and handover of the session on the original leaving network node or gateway node to ensure that the corresponding service is not affected by the leaving of the network node or gateway node.

[112] On the self-service plane, the processing procedure for the network node or the gateway node to exit the broadband wireless access network is as shown in FIG. 12, which specifically includes the following steps:

[113] Step 121: The network node or the gateway node that needs to exit sends an exit request (ie, leave request) message to the adjacent network node or gateway node;

[114] Step 122: After receiving the exit request message, the neighboring network node or the gateway node, which is the management node, performs an exit operation on the network node or the gateway node that needs to exit, and assists in the broadband wireless access network. The exiting network node or gateway node performs cleanup and handover of the corresponding session to ensure that the service carried out by the exiting network node or gateway node is not affected by the exit;

[115] Step 123: The neighboring network node or gateway node is also responsible for re-establishing the network association for the exit event To generate a new network topology map based on various parameters, and send the parameters of the new network topology map to the network node or gateway node that needs to be adjusted for wireless coverage and topology reconfiguration; [116] Step 124: Under the new network topology condition, each related network node or gateway node performs re-calculation of the route, and provides a broadband access service according to the new calculation result.

[117] In the deployment plane, the process flow of the network node or gateway node acting as the deployment node joining the network is shown in the figure.

13 specifically includes the following steps:

[118] Step 131: Set a node device that can serve as a network node or a gateway node to power on, and then, the node device can serve as a node device to be joined;

[119] Step 132: The wireless transceiver in the device senses the surrounding wireless environment, and perceives neighboring neighbor nodes, that is, the neighboring network node or gateway node is perceived;

[120] Step 133: The node device to be joined exchanges information with the neighbor node device, and the neighbor node starts the network to authenticate and authorize the node device to be joined through the management node;

[121] Wherein, the management node may be the neighbor node device itself, or may be another node device or a specially set device as a network node or a gateway node in the network;

[122] Step 134: The management node determines whether the authentication and authorization of the node device to be joined is passed. If not, the node device to be joined is prohibited from joining the network, and the process ends. Otherwise, the step is performed. 135;

[123] Step 135: The node device to be added reports its capability parameter to the neighbor node device.

[124] Step 136: Neighbor node equipment and network negotiation (for example, negotiating with other node devices in the network, or negotiating with the designated node device), calculating and generating new according to deployment planning requirements and related parameters Network topology map, and the parameters of the new network topology map are sent to the node device and the network node or gateway node that needs to be adjusted, for wireless coverage and topology reconfiguration, and then the route is recalculated;

[125] Step 137: The node device to be joined joins the network in the manner of a network node or a gateway node, and accesses the corresponding broadband access service in the network. At this point, the node device to be joined completes the operation of joining the network.

[126] In the deployment plane, the maintenance network processing flow of the network node or the gateway node that is the deployment node is as shown in FIG. 14 , and specifically includes the following steps: [127] Step 141: Each network node or gateway node and the neighbor network node or the gateway node exchange handshake information;

[128] Step 142: The neighboring network node or the gateway node that is the management node determines whether the setter for each network node or the gateway node is exceeded, and if there is no excess, the corresponding network node or gateway is determined. The node is still online, and works normally, and then proceeds to step 141, otherwise, it is determined that the corresponding network node or gateway node has left the network, and then step 143 needs to be performed;

[129] Step 143: The neighboring network node or the gateway node confirms that the corresponding network node or gateway node has left the network due to a fault or movement, and then negotiates with the network to recalculate and generate according to the deployment planning requirements and related parameters. A new network topology map, and the parameters of the new network topology map are sent to the network node or the gateway node that needs to be adjusted, and the wireless coverage and topology reconfiguration are performed;

[130] Step 144: Recalculation of routes by each network node and gateway node under new network topology conditions

[131] Step 145: Clean and switch the session on the leaving network node or gateway node to ensure that the corresponding service is not affected by the leaving process.
