-the first communication device simultaneously carries the data channel service identity and the MMTEL service identity;
-the first communication device carries only the data channel service identity;
-the first communication device carries only the MMTEL service identity;
the interaction mechanism of the first communication device and the second communication device shown in fig. 4 and fig. 5 embodies a combined interaction mechanism that comprehensively embodies whether the first communication device carries the data channel service identifier or the MMTEL service identifier and whether the user opens the data channel service or the MMTEL service.
The interaction mechanism of the first communication device and the second communication device shown in fig. 4 and 5 supports, but is not limited to, the following scenarios:
the data channel service identifier is used in combination with the MMTEL service identifier, i.e. based on a data channel interaction mechanism on the MMTEL service or IMS call basis;
the data channel service identifier is used independently, i.e. the establishment and use of the data channel exist independently, and is not based on MMTEL or IMS calls;
other interaction mechanisms requiring data channel service identification.
In the embodiment of the application, the second communication device may obtain the data channel service identifier sent by the first communication device, and may implement establishment of a data channel in combination with an IMS/5G voice network, or establishment of an independent data channel, thereby supporting more diversified services.
In the following, different interaction scenarios are taken as examples, and an interaction system and an interaction method based on the capability identifier and the interaction mechanism are described.
Interaction scenario (one):
the first communication device has the MMTEL and data channel service capability identifier, and the user has opened the MMTEL and data channel service, see fig. 6, the specific steps are as follows:
step 1: a first communication device initiates a registration request of an MMTEL and a data channel (hereinafter referred to as DC), and carries an MMTEL service capability identifier and a data channel service capability identifier;
step 2: the service capability detection device detects the service capability of the first communication equipment according to the information sent by the first communication equipment and records that the equipment has two service capabilities of MMTEL and DC;
and step 3: service capability detection device queries user service server to obtain service opened by user
And 4, step 4: the user service server replies to the service capability detection device, and the user opens the MMTEL service and the data channel service;
and 5: and the service capability detection device combines the recorded service capability of the first communication equipment and the service opened by the user replied by the user service server to execute the processing of the registration request.
Step 6-step 9: because the first communication equipment has the MMTEL and DC service capabilities and has opened the MMTEL service and the data channel service, the service capability detection device sends a registration request to the basic service controller and the data channel service controller and respectively obtains an MMTEL registration confirmation and a DC registration confirmation;
step 10: the service capability detection device replies MMTEL and DC registration confirmation information to the first communication equipment
Through steps 1-10, the service capability negotiation between the first communication device and the second communication device is completed.
Interaction scenario (b):
the first communication device has an MMTEL and data channel service capability identifier, and the user opens only the data channel service, see fig. 7, and the specific steps are as follows:
step 1: the first communication equipment initiates an MMTEL and DC registration request, and carries an MMTEL service capability identifier and a data channel service capability identifier;
step 2: the service capability detection device detects the service capability of the first communication equipment according to the information sent by the first communication equipment and records that the equipment has two service capabilities of MMTEL and DC;
and step 3: service capability detection device queries user service server to obtain service opened by user
And 4, step 4: the user service server replies to the service capability detection device, the user has opened the data channel service and has not opened the MMTEL service;
and 5: and the service capability detection device combines the recorded service capability of the first communication equipment and the service opened by the user replied by the user service server to execute the processing of the registration request.
There may be two processing mechanisms here:
the first mechanism is as follows:
step 6: the service capability detection device judges that the data channel service can not exist independently of the MMTEL service, needs to be expanded based on the MMTEL service, and the user only starts the data channel service, so that the registration request is rejected, and the rejected information is replied to the first communication device.
And a second mechanism:
step 6-step 7: the service capability detection device determines that the data channel service can exist independently of the MMTEL service, so the service capability detection device sends a registration request to the base service controller and obtains a DC registration confirmation.
And 8: the service capability detection means replies the DC registration acknowledgement information to the first communication device.
And the service capability negotiation between the first communication device and the second communication device is completed.
Interaction scenario (c):
the first communication device has an MMTEL and data channel service capability identifier, and the user opens only the MMTEL service, see fig. 8, and the specific steps are as follows:
step 1: the first communication device initiates an MMTEL and DC registration request, and carries an MMTEL service capability identifier and a data channel service capability identifier.
Step 2: the service capability detection device detects the service capability of the first communication equipment according to the information sent by the first communication equipment, and records that the equipment has two service capabilities of MMTEL and DC.
And step 3: service capability detection device queries user service server to obtain service opened by user
And 4, step 4: the user service server replies the service capability detection device, the user opens the MMTEL service and does not open the data channel service.
And 5: and the service capability detection device combines the recorded service capability of the first communication equipment and the service opened by the user replied by the user service server to execute the processing of the registration request.
Step 6-step 7: the service capability detection device sends a registration request to the basic service controller and obtains MMTEL registration confirmation.
And 8: and the service capability detection device replies the MMTEL registration confirmation information to the first communication equipment.
And the service capability negotiation between the first communication device and the second communication device is completed.
Interaction scenario (iv):
the first communication device only has the data channel service capability identifier, and the user has opened the MMTEL and the data channel service or the user has opened only the data channel service, see fig. 9, the specific steps are as follows:
step 1: the first communication equipment initiates a DC registration request and carries a data channel service capability identifier.
And 2, step: and the service capability detection device detects the service capability of the first communication equipment according to the information sent by the first communication equipment and records that the equipment has the service capability of the data channel.
And step 3: service capability detection device queries user service server to obtain service opened by user
And 4, step 4: the user service server replies to the service capability detection device, and the user opens the MMTEL service and the data channel service (or only opens the data channel service).
And 5: and the service capability detection device combines the recorded service capability of the first communication equipment and the service opened by the user replied by the user service server to execute the processing of the registration request.
The first mechanism is as follows:
step 6: the service capability detection device judges that the data channel service can not exist independently of the MMTEL service, needs to be expanded based on the MMTEL service, and the first communication equipment only carries the data channel service capability identification, so that the registration request is rejected, and the rejected information is replied to the first communication equipment.
And a second mechanism:
step 6-step 7: the service capability detection device determines that the data channel service can exist independently of the MMTEL service, so the service capability detection device sends a registration request to the base service controller and obtains a DC registration confirmation.
And 8: the service capability detection means replies the DC registration confirmation information to the first communication device.
And the service capability negotiation between the first communication device and the second communication device is completed.
