Description
Technical field
The present invention relates to the network communications technology, particularly a kind of method and system of device registration.
Background technology
Packet-switch technology with soft switch and internet protocol-based (IP) is the next generation network technology (NGN) of core, because it is miscellaneous services such as support voice, data and multimedia simultaneously, can satisfy people variation and personalized various demands, thereby become one of focus that present industry pays close attention to the most.
Figure 1 shows that the NGN schematic network structure, this network mainly is made up of soft switch, NGN core net, Session Border Controller (SBC), user access networks and terminal five parts, wherein, terminal part had both comprised the user terminal that directly is connected into user access networks, comprised the Public Switched Telephone Network user terminal that is connected into user access networks by gateway again.
Among whole network, the SBC that occurs as Xin Lingdaili equipment plays an important role: for terminal, SBC is equivalent to soft switch, and for soft switch, SBC is equivalent to terminal, thereby has isolated GNG core net and user access networks, has guaranteed the safety of NGN core net.
Along with popularizing of NGN network, terminal use's quantity and type of service constantly increase, and correspondingly the capacity of SBC are also had higher requirement.Existing increase capacity scheme adopts many modes that SBC simply piles up, and promptly increases the quantity of SBC in the network, and as shown in Figure 2, Fig. 2 is the NGN schematic network structure that has adopted many SBC equipment.But adopt this scheme to dispose a plurality of different server address for the terminal use, and safeguard that these addresses will expend huge workload, simultaneously also be difficult to guarantee between a plurality of SBC equipment, realize the traffic load equilibrium, and then caused can't making full use of of SBC equipment.
In order to reduce maintenance cost, fully improve the disposal ability of SBC equipment and guarantee usage ratio of equipment to greatest extent, a solution has been proposed: in the NGN network, increase a signaling discharge device (SDD) in the prior art, as shown in Figure 3, Fig. 3 is the NGN schematic network structure that has added SDD equipment.SDD is as the unified export abroad of many SBC equipment, and external signaling message at first is received SDD, signaling is distributed on the corresponding SBC equipment according to distribution policy by SDD and carries out signaling process.This just needs constantly to communicate between SDD and the SBC, so that SDD can obtain the state information of SBC equipment in real time, and in time adjusts the signaling distribution policy according to the state of SBC.
In this programme, adopt connectionless User Data Protocol (UDP) message to communicate between SDD and the SBC equipment, Fig. 4 is SBC and SDD communication between devices mode schematic diagram, as shown in the figure, mainly may further comprise the steps:
Step 401:SBC sends registration information to SDD, and request registration is to SDD equipment.
Step 402:SDD carries out authentication to the register requirement of SBC, if authentication is passed through, SDD sends to succeed in registration to SBC and replys.
Step 403: registration is finished, and SDD sends signaling message to SBC.
Step 404:SBC regularly sends the keep-alive message to SDD;
In order to make the operating state of the timely perception SBC of SDD equipment; SBC equipment needs regularly to send the keep-alive message to SDD equipment; if SDD equipment continuously several times; such as the keep-alive message of not receiving that SBC equipment sends 3 times; will think that abnormal conditions have appearred in this equipment; no longer distribute follow-up signaling, thereby guarantee the correctness of signaling process to greatest extent for this equipment.
Under the normal condition, as to successfully receiving the response of information, SDD equipment should the back response message after receiving the keep-alive message that SBC equipment sends.But; a SDD equipment is connected with many SBC equipment in this programme; if, can cause very big influence to the performance of SDD, because this can take the time and space of SDD processing signaling message for the keep-alive message SDD equipment of each SBC equipment back response message all.In view of the importance of SDD equipment in whole network, extra factor should be reduced to minimum to the influence that its performance causes, so for the keep-alive message that SBC sends, SDD can the back response message.
But under the mode that adopts connectionless UPD message to communicate between existing SDD and the SBC, if SBC equipment does not receive response message, operating state that just can't perception SDD equipment, if it is unusual that this just causes SDD equipment to take place, after it recovers normal condition again, because the state of the SBC that writes down among the SDD has become abnormality, SDD equipment will can not send signaling message to SBC equipment more so, and the SBC equipment of the other end and do not know that SDD had once occurred unusually, can not resend register requirement yet, so just cause service disconnection to SDD equipment.
