The Following modules must be loaded before this module:
Usrloc PCSCF
PUA - if reginfo is used.
URI of this Proxy-CSCF.
Example 1.1. pcscf_uri parameter usage
...
modparam("ims_registrar_pcscf", "pcscf_uri", "pcscf.mnc001.mcc001.3gppnetwork.org")
...
How long (in seconds), until pending (uncomplete) Registrations expire
Default value is 30.
Example 1.2. pending_reg_expires parameter usage
...
modparam("ims_registrar_pcscf", "pending_reg_expires", 15)
...
AVP, holding the received information (optional)
Example 1.3. received_avp parameter usage
...
modparam("ims_registrar_pcscf", "received_avp", "$avp(i:42)")
...
Defines, whether a contact should be searched by it's contact only or alternatively by the received IP-Address.
The option may have the following values:
0 Search by Contact-Header only
1 Search by Contact-Header, if this fails, search by Received Information (IP, Port, Proto)
2 Search by Received Information (IP, Port, Proto), if this fails, Search by Contact Header
This Parameter is primarily used by the "is_registered" function.
Default value is 0 (Contact only).
Example 1.4. is_registered_fallback2ip parameter usage
...
modparam("ims_registrar_pcscf", "is_registered_fallback2ip", 2)
...
If set to "1", the module will send PUBLISH regarding changes of the registration (e.g. due to Rx-Information) towards the network core.
Default value is 0 (Do not send PUBLISH).
Example 1.5. publish_reginfo parameter usage
...
modparam("ims_registrar_pcscf", "publish_reginfo", 1)
...
If set to "1", the module will send a SUBSCRIBE for the registration status towards the network core.
Default value is 0 (Do not send SUBSCRIBE).
Example 1.6. subscribe_to_reginfo parameter usage
...
modparam("ims_registrar_pcscf", "subscribe_to_reginfo", 1)
...
How long should the subscription of reg-info towards the packet-core be valid?
Default value is 3600.
Example 1.7. subscription_expires parameter usage
...
modparam("ims_registrar_pcscf", "subscription_expires", 7200)
...
Validate, if the port, from which the request was received, is the same as used during registration.
This Parameter is primarily used by the "is_registered" function.
Default value is 0 (do not ignore Ports).
Example 1.8. ignore_contact_rxport_check parameter usage
...
modparam("ims_registrar_pcscf", "ignore_contact_rxport_check", 1)
...
Validate, if the found contact is really and completely registered.
This Parameter is primarily used by the "is_registered" function.
Default value is 0 (do not ignore registration state).
Example 1.9. ignore_reg_state parameter usage
...
modparam("ims_registrar_pcscf", "ignore_reg_state", 1)
...
Instead of doing a DNS-Lookup on the domain, always send the requests to a specific I-CSCF.
Default value is not set, do the DNS-Lookup.
Example 1.10. force_icscf_uri parameter usage
...
modparam("ims_registrar_pcscf", "force_icscf_uri", "sip:icscf.mnc001.mcc001.3gppnetwork.org")
...
As reginfo operations are processed asynchronously, this parameter defines at what length of the queue, the length should be logged (in order to determine overload)
Default value is 0 (do not log queue length).
Example 1.11. reginfo_queue_size_threshold parameter usage
...
modparam("ims_registrar_pcscf", "reginfo_queue_size_threshold", 42)
...
The function processes a reply to a REGISTER message. It can add, remove or modify location records (in usrloc) depending on Contact and Expires HFs in the REGISTER message.
Meaning of the parameters is as follows:
domain - Logical domain within the registrar. If a database is used then this must be name of the table which stores the contacts.
Same as pcscf_save(), but it will store the registration in a "Pending" state.
Meaning of the parameters is as follows:
domain - Logical domain within the registrar. If a database is used then this must be name of the table which stores the contacts.
Returns true, if the request is following the "learned" service-routes during registration.
Meaning of the parameters is as follows:
domain - Logical domain within the registrar. If a database is used then this must be name of the table which stores the contacts.
Remove existing route-headers and force the Service-Routes, that were learned during registration.
Meaning of the parameters is as follows:
domain - Logical domain within the registrar. If a database is used then this must be name of the table which stores the contacts.
