Control domain change based on network registration condition

An apparatus, comprising:

• a processor;
• and a
• memory that stores executable instructions that, when executed by the processor, facilitate performance of operations, comprising:
• selecting a domain for a communication directed to a user device, wherein the selecting comprises determining a control relationship between the apparatus and a terminating network device of terminating network devices of a terminating network and an availability of an internet multimedia subsystem protocol at the apparatus, wherein the apparatus is home network device of home network devices of a home network, wherein the terminating network is a visited network, and wherein the control relationship is determined based on an access network capability of the terminating network, wherein the control relationship relates to a capability to communicate call control information between the apparatus and the terminating network device;
• sending a request to a data store for first information indicative of whether a first type of communication protocol processing is to be provided for the communication;
• and
• disabling control of the communication by the apparatus based on a determination that there is the control relationship does not exist between the apparatus and the terminating network device;
• and
• sending a query to a data store for second information related to the terminating network device to which the user device is connected, wherein the query comprises an inquiry regarding whether the terminating network is an authorized roaming partner to the home network.

A computer-readable storage device storing executable code instructions that, in response to execution, cause a system comprising a processor to perform operations, comprising:

• performing a domain selection function based on a network registration condition of a user device and whether a call control relationship between a home network device of a home network and a visited network device of a visited network is determined to exist, wherein the relationship relates to a transfer of call control information;
• disabling call control at the home network device based on a result of the performing the domain selection function in response to an internet protocol multimedia subsystem call control being determined not to be available at the home network device and in response to a determination that the home network device and the visited network device do not have the call control relationship;
• sending a query to a data store for information related to the visited network device to which the user device is connected, wherein the query comprises an inquiry regarding whether the visited network is an authorized roaming partner to the home network;
• and
• receiving service domain information and access domain information in response to the query.
