Abstract:
1. One or more non-transitory computer-storage media having computer-executable instructions embodied thereon that, when executed, perform a method of embedding multiple network-access identifiers (NAIs) into a single string for servicing a service request from a mobile device that is normally associated with a first domain, the method comprising: receiving a request, at a second domain, from the mobile device to establish data connectivity with an IMS (Internet protocol multimedia subsystem) network associated with the second domain; receiving a multiple-string format indicator, at the second domain, that indicates that a string includes data that, when ultimately deconstructed, indicate multiple NAIs (network-access identifiers); receiving the string that includes multiple embedded NAIs in a multiple-string format, the multiple-string format including a username and at least one domain identifier separated by one or more delimiters; parsing the string to identify the multiple embedded NAIs; identifying at least one of the multiple embedded NAIs as being associated with the second domain; discovering an S-CSCF (serving call session control function) in the IMS network associated with the second domain; and registering the mobile device with a subscriber server associated with the second domain, the subscriber server including a profile that indicates a set of services available to the device from the second domain.
