Embodiment
In actual applications, can handle,, realize the automatic switchover between the sip server in view of the above, as shown in Figure 2 to obtain the address of sip server automatically to 120 information that provided of OPTION (option) in DHCP (dynamic host allocation protocol) message.
Particularly, the OPTION120 item is made up of binary string usually.When using, can carry out binary string according to the form of OPTION120 item and handle, to obtain the domain name that needs.
Can be at the functional switch that obtains the function setting correspondence of above-mentioned sip server address, to open or to close this function as required.
Particularly, the WAN (wide area network) that can set up the DHCP type on family gateway equipment connects, so that the OPTION120 item from DHCP ACK (affirmation) message obtains the information content that needs.
Can resolve the content of OPTION120 item by the WAN link block of family gateway equipment, therefrom obtain domain-name information and send to the voice module of family gateway equipment, after by voice module the domain-name information of receiving being handled, DNS (domain name system) the inquiry of the domain name interface that module provided that calls family gateway equipment sends the query message that writes down at SRV (service position) to dns server, and handle the response message that dns server returns according to described query message, therefrom obtain the IP address of required sip server, use for voice module.
When the voice module by family gateway equipment gets access to the address of new sip server, can carry out the initialization of voice module again, and by voice module and the pairing sip server link setup in new sip server address that gets access to, to guarantee normally carrying out of voice call function.
The present invention is described in further detail below in conjunction with accompanying drawing.
Behind system initialization, family gateway equipment need be done following configuration: open and obtain the function of sip server address automatically.
Referring to Fig. 3, Fig. 3 is the flow chart that obtains the sip server address automatically of the embodiment of the invention, and this flow process may further comprise the steps:
Step 301, the WAN link block of family gateway equipment is initiated the WAN connection request, sends request message to the DHCP of family gateway equipment module.
Step 302, the DHCP module sends discover (discovery) message to Dynamic Host Configuration Protocol server, has wherein increased the OPTION120 solicited message.Described OPTION120 solicited message also can be carried in other the communication information and send to Dynamic Host Configuration Protocol server.
Step 304, the DHCP module of family gateway equipment sends the DHCP module that request (request) message is given family gateway equipment, has increased described OPTION120 solicited message in the described request message.
Step 305, Dynamic Host Configuration Protocol server send the DHCP module of ack message to family gateway equipment, carry IP address and OPTION120 item in the described ack message;
Step 306, the content that the WAN link block of family gateway equipment is obtained the OPTION120 item from the DHCP module is also resolved, to obtain domain-name information;
Step 307, the WAN link block of family gateway equipment sends to voice module with domain name information;
Step 308, voice module adds " _ sip._udp. " prefix with the domain-name information of receiving, obtains the domain name of sip server, and calls the inquiry of the domain name interface that the DNS module is provided according to this domain name;
Step 309, the DNS module of family gateway equipment is initiated the DNS request according to domain name information, as: make up with the SRV of DNS and write down corresponding query message, and this query message is sent to dns server;
Step 310, dns server sends response message to the DNS of family gateway equipment module, carries the address of the sip server that inquires according to described query message in this message;
Step 311 after the DNS module of family gateway equipment is obtained response message, therefrom parses the IP address of sip server, and this IP address is returned to voice module.
So far, voice module gets access to the address of sip server.If the address of sip server changes, then the initialization voice module carries out link setup by voice module with the address of new sip server.
In conjunction with above description as can be known, the operation thinking that the present invention obtains the sip server address can be represented flow process as shown in Figure 4, and this flow process may further comprise the steps:
Step 410: obtain the OPTION120 item in the DHCP message.
Step 420: the domain-name information in the described OPTION120 item is handled, obtained being used to obtain the domain-name information of sip server address.
Step 430: according to the domain-name information initiation DNS request that is used to obtain the sip server address,
Obtain the address of sip server in view of the above.
In sum as seen, no matter be the method or the devices such as family gateway equipment of this method of support, the present invention obtains the technology of sip server address, can obtain and upgrade the address of sip server automatically, family gateway equipment is automatically switched on the pairing sip server in this address, therefore can guarantee the operate as normal of the voice module of family gateway equipment.
The above is preferred embodiment of the present invention only, is not to be used to limit protection scope of the present invention.
