Problems solved by technology
[0006]When the terminal node leaves the association range of the routing node under abnormal circumstances, or is often idle although it is normally associated with the routing node, it will occupy a network address resource , which causes the limited network address resources of routing nodes to be unable to be fully utilized; because each routing node in WPAN has a limited network address, when the network addresses are exhausted, the routing node cannot allocate to other terminal nodes that request to join Therefore, the association request of other terminal nodes will be rejected, thus affecting the services of other terminal nodes using WPAN

Embodiment Construction
[0024] In the embodiment of the present invention, the routing node obtains the usage status of the network address of one or more terminal nodes managed by it, that is, the network address is allocated, and when it is known that a network address is in the idle state, it takes back the idle network address, So that it can be allocated to other terminal nodes that request to join.
[0025] Routing nodes can periodically manage their own network address resources and reclaim idle network addresses, or according to the communication status of different terminal nodes in the neighbor table, for example: it is found that the terminal node has not communicated within a certain period of time, or, When you find that you have no network address to allocate after receiving an association request from a new terminal node, or when there is no network address that can be allocated to other terminal nodes that need to communicate, manage your own network address resources and withdraw them...

The invention discloses a processing method for a network address and a routing node, wherein the processing method for the network address comprises the following steps: the service condition of the network addresses of one or more terminal nodes assigned by the routing node is obtained; and when the service condition of the network addresses is in an idle state, the routing node takes back the network addresses which are in the idle state. The routing node comprises an acquisition module and a network address management module, wherein the acquisition module is used to acquire the service condition of the network addresses of the terminal nodes assigned by the routing node; and the network address management module is used to take back the network addresses which are in the idle state when the service condition of the network addresses are in the idle state. The embodiment of the invention can take back the idle network addresses, realize the full utilization to the limited network address resource of the routing node, and ensure that more terminal nodes use the service of WPAN under the condition of the limited network address resource as far as possible.
Description
technical field [0001] The invention relates to the technical field of communication, in particular to a network address processing method and a routing node. Background technique [0002] A Wireless Personal Area Network (WPAN for short) is a network composed of multiple devices that are relatively close to each other, and these devices communicate with each other through a certain wireless internal method. In recent years, WPAN technology has rapidly developed into a crucial component of computer networks, and it is also one of the mainstream technologies in the fourth-generation wireless communication and control, and can be used for the second-generation and third-generation mobile communications. Various air interfaces provide seamless roaming connectivity. [0003] In a WPAN, generally one or more devices communicate with the operator network, and other devices in the network communicate with the operator network through these devices. Devices in WPAN are divided int...
