Below respectively with better embodiment to having or not in the NGN network under two kinds of situations of IADMS, the maintenance process of NGN terminal is described.

Consult shown in Fig. 2 A, in the NGN network, be provided with incubator and IADMS.NGN terminal hatching house among the figure is the internal lan of a relative isolation with service provider, can guarantee that the safety of TID and key writes.In the hatching house, can hatch NGN terminal in batches.Whether need NGN terminal hatching house to depend on the real network situation of operator, when operator does not have the hatching house, also NGN terminal incubator can be placed in the service operation net, but TID and key K i transmit by public network, safe coefficient is lower.

In this networking mode, can use incubator to hatch in order to make the NGN terminal, before hatching, must finish the configuration of some default data.Finish this process and can adopt two schemes: one is to finish default configuration by equipment manufacturers on the NGN terminal when equipment dispatches from the factory; The 2nd, the NGN terminal obtains corresponding information by DHCP, and this needs the NGN terminal to support the option (OPTION) of DHCP.

Method one, NGN terminal need the default setting finished before hatching.

1, the IP address obtains mode:

It is that DHCP obtains the IP address that the up NGN terminal of A, ETH is answered default configuration, so that can correctly obtain the IP address during hatching of NGN terminal.

2, default IADMS domain name: the equipment supplier must provide default IADMS domain name on the NGN terminal, and domain name requires and can obtain by Fact Book.The default domain name of the IADMS that identical producer provides should be identical.The IADMS domain name of suggestion is: IADMS.COM

The default password (default CFGPWID) of change key and TID 3, is set: in order to prevent by the TID and the key of counterfeit NGN terminal incubator by SNMP change NGN terminal, the equipment supplier must be provided with the default password of key and TID when dispatching from the factory, and default password is provided in Fact Book.The default password that identical producer provides should be identical, and default password is one 8 a character string.

4, MAC Address: the equipment supplier need print the MAC Address of NGN terminal on device housings and packing.

5, Termination ID (TID): for the equipment supplier when equipment dispatches from the factory on the NGN terminal default value (suggestion for empty string).

Method two: the OPTION by DHCP obtains necessary parameter

1, the IP address obtains mode: the default configuration that is necessary for the NGN terminal.

2, definition OPTION is by the IP address of DHCPserver to NGN terminal configuration incubator.

3, definition OPTION is provided with the default password (default CFGPWD) of changing key and TID by DHCPserver to the NGN terminal configuration.

Consult shown in Fig. 2 B, do not have incubator and IADMS in the NGN network, (Trivial File Transfer Protocol, TFTP) server obtains configuration file from TFTP so the NGN terminal is according to default mode.In order to make the NGN terminal can use incubator to hatch, must finish the configuration of some default data.Finish this process and can adopt two schemes: one is to finish default configuration by equipment manufacturers on the NGN terminal when equipment dispatches from the factory; The 2nd, the NGN terminal obtains corresponding information in DHCP ground process, and this needs the NGN terminal to support the OPTION of DHCP agreement.

Method one: the default configuration that the equipment supplier should finish before equipment dispatches from the factory

1, the default domain name of the TFTP/FTP server of loading configuration file: TFTPSERVER.COM

2, the filename default-config-file of configuration file, filename is defined as follows: producer's name-port information-MAC Address .CFG.As:

IAD208：huawei-108-[0050ba19d349].cfg

IAD132：huawei-132-[0050ba19d348].cfg

3, the loading catalogue of configuration file: the current directory of server

Method two: the OPTION by DHCP obtains necessary parameter

1,, provides the IP address of tftp server to the NGN terminal by DHCPserver according to the siaddr field of DHCP.

2, by self-defined DHCP OPTION field, provide profile name and path to the NGN terminal by DHCPserver.

Below respectively the maintenance process to the NGN terminal under two kinds of networking modes is elaborated:

Consult shown in Figure 3ly, the maintenance process to the NGN terminal that has incubator and IADMS to participate in is as follows:

Step 1, NGN terminal electrifying startup.

Step 2, NGN terminal answer default configuration to obtain the IP address for the DHCP mode.

Step 3, obtain the IP address by DHCP.

If the incubator of step 4, the current configuration of judgement is domain name mode or IP address mode, if the domain name mode then to the domain name of dns server parsing incubator, enters step 5.If configuration is the IP address, then enter step 6.(annotate: if before the NGN terminal is not hatched, the IADMS domain name of default configuration should be the domain name of incubator)

Step 5, to the domain name of DNS server request analysis incubator.

Whether step 6, NGN terminal judges need to manage registration (default value is the needs registration) to incubator.If there is not incubator in the operating environment, then can not register by configuration to incubator.If do not need registration, then enter " the hatching upgrading flow process of 2. not having incubator, IADMS ".

Step 7, send coldstart TRAP, wherein have the MAC Address of NGN terminal self among the TRAP to incubator.

Whether step 8, the current NGN terminal of NGN terminal judges send the management registration above three times to incubator: if do not surpass 3 times, then continue to manage registration to incubator; If surpass 3 times, not response of incubator then is described, enter " the hatching upgrading flow process of 2. not having incubator, IADMS ".

Step 9, manage registration to incubator, comprise in the logon message by TRAP: TRAP (TID, IP address, MAC Address), wherein TID is a null character string, IP is the current IP address of NGN terminal.

Step 10, incubator return registering result, if:

A, do not receive the response of management registration, then return step 8 and register to incubator again.

If the result of B incubator feedback management registration is failure,, enter " the hatching upgrading flow process of 2. not having incubator, IADMS " then not in the management that receives incubator.

If the result of C incubator feedback management registration is success, then receive the management of incubator, enter step 11.

Step 11～13, NGN terminal receive the management of incubator, and finish hatching process under the controls of incubator:

A, (producer's title, product type, the port number of step 11) incubator inquiry NGN terminal generate the TID and the Ki (KI) of this NGN terminal.

B, (the step 12) incubator is set to TID and the Ki (KI) that generates in the NGN terminal, before TID and Ki are set, incubator need provide the default modification TID and the password CFGPWD of key, if password CFGPWD incubator correctly could be provided with TID and Ki; Incubator also needs to provide the domain name of IADMS in addition; If the IP address of NGN terminal need change static configuration into, incubator also needs to generate static ip address according to the MAC Address of NGN terminal, and is set in the NGN terminal.

C, (step 13) incubator modification password CFGPWD.

Step 14, for for the NGN terminal in the hatching house, finish to this hatching process, the NGN terminal will be de-energized, start powers on when the user uses.

For for the NGN terminal of public network hatching, hatching process finishes, but needs webmaster to issue a device reset order.

Step 15～23, this process and step 2～10 are basic identical, and different is to manage registration to the IADMS of incubator configuration.

Step 24, IADMS are provided with the configuration of NGN terminal, comprising:

A, auto-update sign: whether the NGN terminal opens the auto-update function.

B, program version number: the program version of depositing on tftp server number is used for the comparison program version and whether needs upgrading.

C, loading configuration file sign: whether need to load download configuration file from the tftp server.

IP address, path and the profile name of the tftp server at D, configuration file place;

The IP address of the tftp server at E, program file place, path and program file title;

These three parameter values that IADMS issues are: auto-update sign, program version number, loading configuration file sign.

Step 25, judgement auto-update sign.If the auto-update function is opened, promptly sign is expressed as " permission auto-update ", then enters step 26; If the auto-update function is closed, promptly sign is expressed as " not allowing auto-update ", then enters step 31.

Step 26, comparison program current version number and the version that IADMS issues need oneself to judge whether upgrading by the NGN terminal.Upgrading then enters step 27 if desired; If do not need the upgrading enter step 31.

Step 27, " the loading configuration file sign " that issue according to webmaster are judged: load if desired and then enter step 28; If do not need to load then enter step 29.

Step 28, NGN terminal are from the tftp server download configuration file.

Step 29, NGN terminal are from the tftp server file that downloads.

Step 30, NGN terminal loads program file enter step 33.

Step 31, " the loading configuration file sign " that issue according to webmaster are judged: load if desired and then enter step 32; If do not need to load then enter step 33.

Step 32, NGN terminal are from the tftp server download configuration file.

Step 33, carry out service log-on to soft switch.

Consult shown in Figure 4ly, do not have the NGN terminal maintenance process of incubator/IADMS as follows:

Step 1, NGN terminal electrifying startup.

It is that DHCP obtains the IP address that step 2, NGN terminal are answered default configuration.

Step 3, obtain the IP address by DHCP.

Whether step 4, NGN terminal judges need to manage registration (default value is the needs registration) to incubator.Should dispose under this pattern does not need to register to incubator; If be configured to and register to incubator, then enter " the hatching upgrading flow process that 1. incubator, IADMS are arranged ".

Step 5, judge whether the NGN terminal has disposed and open the auto-update functional switch.If the auto-update functional switch cuts out, then directly enter step 18; If the auto-update functional switch is opened, then directly enter step 6.

If the default configuration of step 4 is to the incubator registration, but does not have incubator in the environment, then after responding, the judgement incubator can not forward this step to from " the hatching upgrading flow process that 1. incubator, IADMS are arranged " yet.

The TFTP domain name of step 6, parsing default configuration.Get nowhere then progressive step 18 if resolve; If resolve successfully, enter step 7.

Step 7, NGN terminal are got configuration file according to default configuration filename (default-config-file), default path (current path) from tftp server.

If step 8 is got the configuration file success, then enter step 9; If the configure file gets nowhere then enters step 18.

Step 9, read the version number in the configuration file, need to judge whether the ROMPaq file; Upgrading then enters step 10 if desired; If do not need the upgrading enter step 16.

Step 10, according to the program location tftp server address, path and the configuration filename that dispose in the configuration file, from the tftp server file that downloads.

Step 11, loading procedure file.

Step 12, equipment restart.

Whether step 13, NGN terminal judges need to manage registration (default value is the needs registration) to IADMS.Should dispose under this pattern does not need to register to IADMS; If be configured to and register to IADMS, then enter " the hatching upgrading flow process that 1. incubator, IADMS are arranged ".

Step 14, judge whether the NGN terminal has disposed and open the auto-update functional switch.If the auto-update functional switch cuts out, then directly enter step 18; If the auto-update functional switch is opened, then directly enter step 15.

If the default configuration of step 13 is to the IADMS registration, but does not have IADMS in the environment, then after responding, judgement IADMS can not forward this step to from " the hatching upgrading flow process that 1. incubator, IADMS are arranged " yet.

Step 15, resolve the tftp server domain name, and drive configuration file from tftp server according to default path, filename.

If the configuration file CRC effect on step 16 tftp server is identical with the configuration file of current use, then do not need loading configuration file, enter step 19; Otherwise, illustrate that configuration file needs to load, enter step 17.

Step 17, loading configuration file enter step 19.

Step 18, when going wrong, loading system default configuration file guarantees that the NGN terminal normally moves.
