......
Above step 201～203 are the probe messages of authentication server by the reception detecting customer terminal, set up the process of the detection record of this detecting customer terminal then.The order of above step and subsequent step can be adjusted as required.
Customer end A initiates to land normally flow process to authentication server, can send to authentication server by sip message and land request, has comprised the identification information that is used to identify this customer end A in this request, can be the cell-phone number etc. of customer end A in the present embodiment.
Authentication server is inquired about corresponding detection record, the detection record as shown in step 203 according to the phone number of customer end A in database.
If customer end A was not initiated probe messages to authentication server before step 204, then in this step, authentication server can't inquire the detection record corresponding with the customer end A cell-phone number, in this case, authentication server can send the landing approach that uses the SVN tunnel to land to customer end A, and customer end A can be landed the network to VOIP according to this landing approach.
If customer end A had sent probe messages by step 201 before step 204, and authentication server has been set up the detection record of customer end A by step 202～203, then in this step, be recorded as if inquire to survey: the cell-phone number of customer end A--invite right value field " 1 ", then illustrate in customer end A to there not being SIP ALG between the authentication server, then authentication server can return the SIP landing approach to customer end A, and customer end A can be landed the network to VOIP according to this landing approach.
If the detection that inquires is recorded as the cell-phone number of customer end A--invite right value field " 0 ", then illustrate in customer end A to there being SIP ALG between the authentication server, then authentication server can return the HTTP+RTP landing approach to customer end A, and customer end A can be landed the network to VOIP according to this landing approach.
Present embodiment sends the invite message as probe messages by detecting customer terminal, can be so that authentication server be directly judged the residing network environment of present client, treat that client sends when landing request, authentication server can be according to surveying record, directly provide suitable landing approach to land network to VOIP to client, with time of client detection network environment from before be reduced in the 1s and can finish in more than ten second, having saved client landed to the time of VOIP network, improved and landed efficient, improved user experience.
With reference to Fig. 3, be the method flow diagram of the embodiment of the invention two.
In the present embodiment, customer end B will be landed the network to VOIP, and login method can comprise:
In the present embodiment, detecting customer terminal a is by sending the RTP message as probe messages to authentication server, come media channel UDP (the User Datagram Protocol in the detection network, User Datagram Protocol) whether port is open mode, thereby can determine the network scenarios of detecting customer terminal a, and then can determine to be fit to the landing approach of detecting customer terminal a.
Because udp port is a lot, for example the voice flow port of IMS use is from 10000-65534, fire compartment wall not necessarily can all be opened these ports, so before detecting customer terminal a sends the RTP message, at first detecting customer terminal a and authentication server are held consultation, and to determine to send the port of RTP message, the identification information that can also write down the detecting customer terminal a that consults in authentication server is as prestoring identification information, in the present embodiment, the identification information that prestores is the cell-phone number of detecting customer terminal a.Be example as the udp port of consulting to determine with port one 5000,30000,45000 in the present embodiment.
At first, detecting customer terminal a is added into identification information in the general RTP message, and in the present embodiment, probe value is the cell-phone number of detecting customer terminal a.Concrete, detecting customer terminal a adopts general RTP message, in the payload of this message, preceding 15 cell-phone numbers of inserting detecting customer terminal a, remaining bit is inserted the random value that detecting customer terminal a uses when authentication server authenticates, detecting customer terminal a is sent to the RTP message that generates respectively in the port one 5000,30000,45000 then.
In the present embodiment, suppose that authentication server does not receive the RTP message at port one 5000, illustrate that then this port is in closed state, then in authentication server, can write down the information that is used to show this udp port sealing, be 0 by the authenticator segment value that port numbers is set in the present embodiment, represent closed state, the detection of this detecting customer terminal a of foundation is recorded as:
Detecting customer terminal a cell-phone number--port one 5000 verifying fields " 0 "
If at port 30000, can receive the RTP message in 45000, can also judge further whether the RTP message that receives is the message of the detecting customer terminal a transmission of negotiation, concrete can judge whether the identification information in the RTP message is identical with the identification information that prestores in the authentication server, also promptly in the cell-phone number of the detecting customer terminal a of the negotiation of authentication server record, search whether the cell-phone number that carries in this RTP message is arranged in the present embodiment, if have, illustrate that then this port is an open state to this detecting customer terminal a, then in authentication server, write down the information that is used to show this udp port opening, be 1 by the authenticator segment value that port numbers is set in the present embodiment, represent open state, the detection of this detecting customer terminal a that then sets up in this step is recorded as:
Detecting customer terminal a cell-phone number--port 30000 verifying fields " 1 "
Detecting customer terminal a cell-phone number--port 45000 verifying fields " 1 "
If in the cell-phone number of the detecting customer terminal a of the negotiation of authentication server record, search less than the cell-phone number that carries in this RTP message, promptly do not receive the RTP message of detecting customer terminal a at port 30000,45000 yet, the RTP message that receives simultaneously is the message that another detecting customer terminal b sends, and then is recorded as except the detection that can write down this detecting customer terminal a in this step:
Detecting customer terminal a cell-phone number--port 30000 verifying fields " 0 "
Detecting customer terminal a cell-phone number--port 45000 verifying fields " 0 " can also be created and the corresponding detection record of identification information in the RTP message, also promptly create the detection record of detecting customer terminal b:
Detecting customer terminal b cell-phone number--port 30000 verifying fields " 1 "
Detecting customer terminal b cell-phone number--port 45000 verifying fields " 1 "
So that detecting customer terminal b when landing demand, directly is back to detecting customer terminal b according to this detection record with the corresponding landing mode by authentication server.
Above step 301～304 are the probe messages of authentication server by the reception detecting customer terminal, set up the process of the detection record of this detecting customer terminal then.The order of above step and subsequent step can be adjusted as required.
Customer end B initiates to land normally flow process to authentication server, can send to authentication server by sip message and land request, has comprised the identification information that is used to identify this customer end B in this request, can be the cell-phone number of customer end B in the present embodiment.
Authentication server is inquired about corresponding detection record, the detection record as shown in step 304 according to the phone number of customer end B in database.
Step 307 is returned corresponding landing approach according to Query Result and detection record to customer end B.
If customer end B was not initiated probe messages to authentication server before step 305, then in this step, authentication server can't inquire the detection record corresponding with the customer end B cell-phone number, in this case, authentication server can send the landing approach that uses the SVN tunnel to land to customer end B, and customer end B can be landed the network to VOIP according to this landing approach.
If customer end B had sent probe messages by step 301 before step 305, and authentication server has been set up the detection record of customer end B by step 302～304, then in this step, be recorded as if inquire to survey: the cell-phone number of customer end B--port 30000 verifying fields " 1 ", then illustrate in 30000 pairs of customer end B of port open, then authentication server can return SIP landing approach (normal mode) to customer end B, can also comprise open port numbers in this landing approach, so that customer end B is landed the network to VOIP according to this landing approach from open port numbers.
Present embodiment sends the RTP message as probe messages by detecting customer terminal, can be so that authentication server be directly judged the open state of present udp port to client, treat that client sends when landing request, authentication server can be according to surveying record, directly provide suitable landing approach to land network to VOIP to client, with time of client detection network environment from before be reduced in the 1s and can finish in more than ten second, having saved client landed to the time of VOIP network, improved and landed efficient, improved user experience.
