Wireless access network [74] can be formed in self-service may be provided by the wireless access information exchange between the gateway node and the network node is a terminal node of the self-service mode.

The structure of the radio access network [75] may be of the self-service model shown in Figure 5, wherein the gateway node and the network nodes in the self-mode are realized by the self-network terminal device having a predetermined processing function self network node and the gateway node, the corresponding node gateway (i.e., self-gateway node) and the network node (i.e., self network nodes) corresponding self-plane, the self-plane gateway node is connected to a wired network and information exchange . It may be provided by the self-service terminal node plane broadband wireless access service interacting i.e. the radio signal between the node and the terminal node self-plane, and wireless broadband access through self-plane.

[76] As can be seen, it is possible to obtain the desired service area through a radio access network of self-service mode shown in Figure 5 to provide complete coverage of wireless services.

[77] On the basis of the radio access network of self-service mode, the further expansion of the range for the respective wireless access radio coverage or improve the quality of service (e.g., railroad, highway, etc.) for a particular region, but also can be manually deploying a respective gateway node and the network node, i.e., to establish the appropriate network deployment plane through the corresponding gateway node and the network node, thereby providing broadband access to the corresponding terminal node.

[78] shown in Figure 6, the plane of the network device and a network node gateway node, a gateway node is deployed and deployment of network nodes is called deployment plane, obtained more particularly by setting artificially gateway nodes deployed and deployment of network nodes wireless signal coverage and good quality of service access, thereby providing better service to a user terminal like a terminal node.

[85] When the terminal receives two nodes in the same plane inch inch wireless signal is determined according to a certain rule to select a broadband wireless access plane, in order to carry out the corresponding operations, e.g., specific information can be correspondingly set in advance according to the selection choice flat, or, according to two different radio signal quality of the access plane of the plane selection, and the like; only when the terminal node receives a radio signal inch plane, unconditionally performs wireless broadband access through the plane.

[86] (b) a fusion model [87] As shown in FIG. 8, the merge mode refers to deploy self plane and the plane of the desired radio cover the same service area as a fusion mode, i.e., self-plane and deploy nodes in a completely plane try the same position together form a full coverage of the broadband wireless access network, nodes on two planes forming a full area coverage inch consider not only the present node is formed to cover a plane therewith and topology, with the need to consider an alternative inch Effect of a node plane and its coverage topology.

[88] In this mode, the terminal node can only receive wireless signals of a plane, and the use of wireless broadband access plane, i.e., carry out the corresponding operations by the plane.

[89] (c) Mixed Mode

[90] As shown in FIG. 9, the mixed mode refers to deploy self plane and the desired plane of the same service area with radio coverage embodiment inch preclude the use of superimposition pattern and integration mode, i.e. the presence and integration mode with the overlay mode inch. Self node plane and a plane forming a full deployment in the coverage area of ​​coverage inch and topology into account not only of the present node with the formation of a plane, in cases where the affected node also consider another plane and its coverage topology; For example, in some areas, the two planes are each trying to form a full coverage of the broadband wireless access network, in some areas, the need to cooperate with each other two planes, each node in exactly the same position on different planes together form a full-try coverage of broadband wireless access network.

[91] When the terminal node of the same wireless signal received inch inch two planes is determined according to certain rules to select a broadband wireless access plane; only when the terminal node receives a radio signal inch plane, the plane used unconditionally wireless broadband access.

[107] This step is particularly inches determines whether or not a given handshake its neighboring network nodes or gateway nodes has not been received, the corresponding set inch Ultra inches;

[108] Step 113: The broadband wireless access network reconfiguration, updating the respective topology;

[109] Specifically: a network node or gateway node does not receive the handshake message for a network node or a gateway node in a predetermined inter-inch, it is considered a gateway or a network node or a mobile node failure has left the network, the adjacent network or gateway node to negotiate with the network, in accordance with various parameters in order to recalculate a new generation of network topology and the need to adjust the parameters sent to the new network topology of the network or gateway node, and to facilitate wireless coverage topology reconfiguration;

[110] Step 114: under the conditions of the new network topology, network or gateway node to re-calculate the route, and provide access to broadband services based on the calculation result;

[111] Step 115: Effect of the original for cleaning and leaving a network node or switch sessions on a gateway node, in order to ensure that a corresponding service from the network node or gateway node departure.

[112] plane at a self network node or gateway node of a broadband wireless access network exits the process flow shown in Figure 12, includes the following steps:

[113] Step 121: the need to exit the network or gateway node sends a neighbor network node or gateway node exit request (i.e., Leave Request) message;

[114] Step 122: As the adjacent network management node or gateway node receives the withdrawal request message, the network node or gateway node of the need to perform exit withdrawal operation, and to assist in a broadband wireless access network exit the network or gateway node and switch to clean up the corresponding session in order to ensure conducted through the exit network node or gateway node of the service will not be affected by its withdrawal;

[115] Step 123: the adjacent network node or gateway node is also responsible for the event to exit and re-negotiate the network to generate a new network topology recalculated based on various parameters, and the parameters of the new network topology in FIG. distributed network or gateway node need to be adjusted in order to reconfigure the topology and radio coverage; [116] step 124: under the conditions of the new network topology, the relevant network node or a gateway routing node recomputed, and provide broadband access services according to new calculations.

[120] Step 133: node device and a neighboring node device to be added to the exchange of information by authenticating and authorizing the neighbor nodes of the node device to be added to the work by the network management node starts;

[121] wherein, said management node may be the neighbor node device itself, the device may be of other nodes as network devices or specially provided or gateway node of the network;

[122] Step 134: the management node judges the authentication and authorization of the node to be added by the equipment is, if not through, to be added to the node device added to the network is prohibited, and ends the current process, otherwise, perform step 135;

[123] Step 135: the node device to be added to their reported capability parameters to the neighboring node device;

[124] Step 136: the neighbor node device and a network negotiation (for example, among the other devices in the network nodes and consultation, or be negotiated between the device and the specified node), according to the requirements and deployment planning parameters, calculates and generates a new issued to the device and network node or gateway node of the need to adjust network topology, and the new parameters of the network topology, in order to reconfigure the topology of radio coverage and then re-calculate the route;
