Login state and current information in net.
IMS terminal is when IMS domain is registered, and log-on message can be stored directly in ownership signing server.
Therefore IMS terminal can obtain login state from ownership signing server.
In prior art during actively setting up calling connection, the information in net of purpose contact person is permissible
Detected by ownership signing server, but and be not yet stored into belonging in signing server, because now
Have technology set up during calling connects every time actively all can the information in net of testing goal contact person,
Therefore need not storage, it is not required that know in advance.And the embodiment of the present invention needs to know that target joins in advance
It is the information in net of people, it is therefore desirable to the information in net of object contact person is stored to ownership signing service
In device, and being the most stored before caller connection request is set up, therefore the embodiment of the present invention triggers and returns
Belong to signing server and obtain the time point difference of object contact person information in net.Can be when default
Between section trigger, it is also possible to be to trigger in real time.
IMS terminal storage the login state of each contact person and information in net be all current point in time each
The up-to-date login state of contact person and up-to-date information in net.In order to highlight this, the embodiment of the present invention is referred to as
Current login state and current information in net.
Step 103: according to the login state current with described object contact person and current information in net,
Determine and set up, with described object contact person, the caller input field that calling is connected.
Concrete, when the login state that described object contact person is current is registered state, and current staying
When net information is voip network, is set up by described IMS domain and be connected with the calling of described object contact person.
When the current login state of described object contact person is unregistered state or current information in net is
During non-voip network, set up by CS territory and be connected with the calling of described object contact person.
The login state of described object contact person is unregistered state or described information in net is non-voip network
Including the following two kinds situation: the login state of object contact person is unregistered state, or object contact person
Login state is login state but information in net is non-voip network.
Embodiments provide a kind of caller access domain selection method, in IMS terminal active and target
During contact person sets up calling connection, obtain object contact person, from the contact person stored, currently
Login state and current information in net corresponding relation in, it is thus achieved that the registration shape current with object contact person
State and current information in net, according to the login state current with described object contact person and current staying
Net information, determines and sets up, with described object contact person, the caller input field that calling is connected.Owing to target joins
It is the current login state of people and current information in net is all current time, existing thus without occurring

Step 201: obtain the contacts list of described IMS terminal.
IMS terminal, after IMS domain succeeds in registration, can read IMS terminal contacts list.Contact person arranges
It is one or more that table includes hiding in contacts list and address list, and described hiding contacts list includes
Do not store the contact person to address list.
In actual applications, some contact persons are had to be not stored in the contacts list of IMS terminal,
But IMS terminal was also actively set up calling and was connected with these contact persons, can be now that IMS terminal is built
A vertical stealthy contacts list, the most stealthy contacts list, it is because user at IMS
Terminal can't see this stealth contacts list.Hide each contact in contacts list in actual applications
People is usually the people that user seldom contacts, in order to avoid the contact person of storing excess in hiding contacts list,
Cause the data volume belonging to signing server process relatively big, can by hiding contacts list the longest time
Between the people that do not contacts of section delete, concrete may include that detects the most actively sets up institute in Preset Time
When stating the calling connection of the second contact person in hiding contacts list, delete in described hiding contacts list
The second contact person.
After deleting the second contact person in hiding contacts list, also avoid the need for belonging to signing server
Monitor login state and the information in net of the second contact person again, therefore can be to ownership signing server
Sending to cancel and described second contact person is unsubscribed message, concrete may include that to described ownership
Signing server sends to cancel and obtains the current information in net of described second contact person and current registration
State unsubscribe message.
Step 202: generate the subscription message including described contacts list.
