Description
Technical field
The present invention relates to communication technical field, relate in particular to a kind of method that improves point-to-point peer-to-peer communications stability in the cordless communication network, the main index of communication related among the present invention is according to communication.
Background technology
P2P (Peer-to-Peer, point-to-point equity) communication provides a kind of non-centralized data resource sharing mode, and in the P2P network, network terminal node both can be used as the sender of resource, also can be used as the recipient of resource.In half at present classical distributed P2P network configuration, when terminal node during as the sender of resource, it sends the address information of the network at the identification information of resource and own place to its desire of resource lookup server registration; The resource lookup server is associated resource identification with the network address, be stored in the database; When the other-end node will obtain certain resource, the network address that it at first is associated with described resource identification by the resource lookup whois lookup, promptly resource sender's the network address obtains resource by visiting this network address then.
If the node of forming the P2P network is with the wireless mode access network, then this P2P network can be described as wireless P2P network.The wireless terminal node can pass through multiple wireless access way such as CDMA (Code-Division Multiple Access, code division multiple access), GPRS (General PacketRadio Service, GPRS), WLAN (Wireless Local Area Network, WLAN (wireless local area network)) etc. insert interconnection, form wireless P2P network.Because the diversity of wireless access way, characteristics such as the mobility of wireless terminal make wireless P2P network be subjected to the less-restrictive in time and space, can provide convenient flexible services to the user.Therefore, wireless P2P communication service has good development prospect.
But, to compare with wired P2P network, wireless P2P network also faces new problem: when wireless terminal node during as the supplier of resource, because it may move between multiple heterogeneous networks, can cause the resource node address to change; In addition, compare with cable network, wireless network signal is affected by environment easily, and the probability that wireless terminal disconnects with network in moving process is also than higher.Above factor can reduce the stability of wireless P2P network service.
Solution to this problem has at present:
Terminal node is in the process of carrying out P2P communication, if a side place network that sends as resource can not continue to use, then the transmit leg wireless terminal needs search network again, then to the new network address of resource lookup server registration; A side who receives as resource when unavailable, can suspend current ongoing communication in the network address that detects transmit leg, initiates query requests to the resource lookup server again, after finding the new network address, uses new address to proceed to communicate by letter.The major defect of this kind scheme is the communication disruption that possible cause the long period.
Use mobile IP technology can solve the problem that wireless network address changes preferably.Mobile IP technology utilization agent skill group can make terminal not change with real network in order to the network address of communicating by letter with the IP tunnel encapsulation technology, thereby guarantees the stability of wireless communication.But mobile IP service needs the special-purpose network equipment to provide support, and the realization mechanism complexity, and with high costs, if telecom operators do not provide mobile IP service, this programme can't play a role.
