The method includes utilizing position server as re-orienting server and requesting query equipment to send SIP message to it; converting the message the SIP stack receives in the position server into the routing inquiring request format and transmitting the converted message to routing inquiring module; sending corresponding information to query requesting equipment with the SIP stack in the position server based on the result returned from the routing inquiring module; and returning the response message to the position server in the query requesting equipment. The present invention makes it possible to complete automatic routing inquiring without needing artificial intervention and maintaining the routings of the position server in the soft exchange equipment, resulting in saving in memory and other system resource.
Description
Technical field
The present invention relates to the routing inquiry technical field, be meant a kind of method especially to location server inquiry route.
Background technology
In next generation network (NGN), the route among the NGN, the i.e. corresponding relation of number segment, gateway ip address and port numbers etc. have been stored on the location server (LS).When Softswitch makes a call to a destination Mobile Station International ISDN Number, need know the information such as gateway ip address, port numbers of the other side's Softswitch, therefore, Softswitch will be inquired about route by certain vlan query protocol VLAN to LS.
In the prior art, generally can pass through webpage (Web Page) technology, or IP phone Routing Protocol (TRIP), or light directory access protocol (LDAP), or location-based service agreement (SLP), or open settlement protocol vlan query protocol VLANs such as (OSP) is inquired about upward route of LS.
1, uses Web Page technology and carry out routing inquiry.When system operators is come to LS inquiry route by the mode of Web Page, use HTTP(Hypertext Transport Protocol) between operating desk and the LS, LS is as the Web server end, and operating desk is as the Web client.
The shortcoming that application Web Page carries out routing inquiry is: the query script of route must have operating personnel's participation, can not break away from manual and realization inquiry automatically, so this method is not suitable for the Softswitch employing.
2, use the TRIP agreement and carry out routing inquiry.The TRIP agreement is used for carrying out route propagation between the LS originally, but Softswitch also can be used this agreement from LS acquisition route.
The shortcoming that application TRIP agreement is carried out routing inquiry is: in a single day Softswitch adopts the TRIP agreement to come to LS inquiry route, its final result is that the route on Softswitch and the LS reaches fully synchronously, and promptly each Softswitch all must be preserved a large amount of routes.Like this, Softswitch not only will be supported complicated TRIP agreement, has the mutual function of route, also will additionally take a large amount of internal memories and preserve all routing iinformations on the local LS, has both increased the burden of Softswitch, has also wasted a large amount of system resource.
3, use ldap protocol and carry out routing inquiry.When Softswitch by ldap protocol during to LS inquiry route, LS is as ldap server, Softswitch is as the LDAP client.
The shortcoming that the application ldap protocol carries out routing inquiry is: because ldap protocol is the option agreement of Softswitch operation, rather than essential option agreement, therefore, when using ldap protocol solution routing inquiry problem, must determine earlier whether this Softswitch support ldap protocol, if, can directly use, otherwise, after needing earlier this Softswitch to be developed ldap protocol again, could use.Generally, Softswitch is not support ldap protocol, develops ldap protocol again, is certain to increase cost, also can increase the burden of Softswitch simultaneously.
Use SLP agreement or OSP agreement and carry out routing inquiry, its method is similar with the application ldap protocol.Similarly, because SLP agreement and OSP agreement are not the agreements in the NGN field, concerning Softswitch, all be a kind of brand-new agreement, need exploitation again equally, so not only increase application cost, prolong the Products Development cycle, also increased the burden of Softswitch.
Summary of the invention
In view of this, the invention provides a kind of method, make whole query script not need manual intervention, and make the equipment of routing inquiry demand need not to store a large amount of routing iinformations, or therefore develop New Deal to location server inquiry route.
Technical scheme of the present invention is achieved in that in order to achieve the above object
A kind of method to location server (LS) inquiry route is applied in the next generation network, and this method may further comprise the steps:
A, with location server as Redirect Server, the equipment of request inquiry sends session initiation protocol (SIP) message to it;
The message that b, location server receive its SIP stack converts the routing inquiry request form to, and switched message is sent to routing inquiring module;
The result that SIP stack in c, the location server is returned according to routing inquiring module sends corresponding information for the equipment of request inquiry;
The equipment of d, request inquiry is replied response message to location server.
Preferably, after SIP stack in the location server receives the described message of step a, at first the request query facility that sends this message is authenticated, if this equipment is by authentication, then location server converts the message that receives to its inner routing inquiry request form again, and continue to carry out subsequent step, otherwise the SIP stack in the location server is not directly passed through the information of authentication to the device replied of request inquiry.
Preferably, the described routing inquiring module of step b is inquired about in the routing information base of this locality, and this Query Result is returned to SIP stack on the location server.
Preferably, the described corresponding information of step c is:
When enquiry module finds the route that the request query facility requires to inquire about, the information that the equipment transmission route that the SIP stack in the location server is inquired about to this request has been found;
When enquiry module does not find the route that the request query facility requires to inquire about, the information that the equipment transmission route that the SIP stack in the location server is inquired about to this request is not found.
Preferably, described having found comprises the number segment that is complementary with called number, the gateway address of finishing this calling, port numbers and application protocol type at least in the information;
Preferably, the form of described information is the message status sign indicating number.
Preferably, the equipment of described request inquiry can be Softswitch, also can be non-Softswitch.
Preferably, described type of message is for inviting message (INVITE), take leave of message (BYE), abandoning message (CANCLE), option message (OPTIONS), response message (ACK) or logon message (REGISTER).
Use the present invention, in the NGN network, as long as the equipment of request inquiry is supported session initiation protocol (SIP) agreement, all can be with Session Initiation Protocol as agreement to LS inquiry route, automatically carry out routing inquiry, and do not need manual intervention, therefore improved the efficient of inquiry; Nearly all support Session Initiation Protocol owing to all Softswitch simultaneously, thereby avoided the exploitation New Deal, saved cost and accelerated the Products Development cycle; In addition, when Softswitch uses Session Initiation Protocol to carry out routing inquiry, only preserve most recently used sub-fraction route, do not need because of with LS on route keep preserving a large amount of routes synchronously, so saved system resource such as internal memory greatly.
