摘要： A device may identify a first set of radio frequency (RF) spectrum bands supported by a visited public mobile network (VPMN) for a first radio access technology (RAT), and may identify a second set of RF spectrum bands supported by a user device for the first RAT. The device may compare the first set of RF spectrum bands and the second set of RF spectrum bands, and may determine whether the user device and the VPMN support a same RF spectrum band for the first RAT. The user device may be registered to use the first RAT when the user device and the VPMN support the same RF spectrum band for the first RAT, or the user device may be registered to use the second RAT when the user device and the VPMN do not support the same RF spectrum band for the first RAT.

摘要： A user device may be provisioned with a list of paths for connecting to a network. A method may include determining that the user device has attached to a visited network and sending the visited network an indication of connectivity capabilities associated with the network. The method may include receiving an indication of one or more paths established from the visited network to the network based on capabilities of the visited network. The one or more paths may be included in the list of paths. The method may include transmitting data to or from the user device via a first path of the one or more paths.

摘要： A device may receive a request to access a network service from a user equipment (UE) roaming on a visiting public mobile network (VPMN). The device may receive UE radio frequency (RF) band information that identifies a UE supported set of RF spectrum bands, and may receive VPMN RF band information that identifies a VPMN supported set of RF spectrum bands. The device may determine whether to permit or deny access to the network service based on the UE RF band information and the VPMN RF band information, and may provide an instruction to permit or deny access to the network service based on the UE RF band information and the VPMN RF band information.

摘要： A method including receiving, at a CSCF (Call Session Control Function) portion of a home network in which a mobile station is subscribed, an IMS (IP Multimedia Subsystem) registration request from the mobile station via a visited network to which the mobile station is attached; establishing an SIP (Session Initiation Protocol) session between the mobile station and the CSCF server in response to the received IMS registration request; receiving, at the CSCF server, a SIP INVITE message from the mobile station during the SIP session, wherein the SIP INVITE requests use of a service; obtaining an identifier for the visited network; obtaining, in response to receiving the SIP INVITE message, a first roaming policy based on the identifier for the visited network; determining whether the SIP INVITE message is acceptable based on the obtained first roaming policy and the service requested by the SIP INVITE message; and sending a response for the SIP INVITE message to the mobile station, wherein the response is based on the determination whether the SIP INVITE message is acceptable.
