Abstract: A mobile device, via a roaming platform, can switch IMSIs (e.g., Home IMSI-1, Roamer IMSI-2, etc.) depending on a location of the mobile device. Upon switching IMSIs, the roaming platform can forward the update location to an HLR of the home network and roaming network. If the MMSC on the home network receives an MMS message, the MMSC on the home network may query the HLR for a current location. From the query, if the message recipient is roaming, the MMSC on the home network may communicate with the MMSC on the roaming network to deliver the message. As a result, the roaming network can handle the routing of the message without a data session routed back through the home network.

Abstract translation: 通过漫游平台的移动设备可以根据移动设备的位置来切换IMSI（例如，家庭IMSI-1，漫游器IMSI-2等）。 在切换IMSI时，漫游平台可以将更新位置转发到家庭网络和漫游网络的HLR。 如果家庭网络上的MMSC接收到MMS消息，家庭网络上的MMSC可以向HLR查询当前位置。 从查询中，如果消息接收者正在漫游，家庭网络上的MMSC可以与漫游网络上的MMSC进行通信，以传递消息。 因此，漫游网络可以处理消息的路由，而无需通过家庭网络路由的数据会话。
