Abstract
A method, system, and terminal for handling or processing roaming errors between networks that can support broadcast services. When a roaming service between networks is requested, if a user authentication request is unsuccessful due to non-matching identification information between the networks, a corresponding error message is delivered to the subscriber terminal and network information that has been recently updated using various methods is provided such that repetitive requests and responses for authentication can be avoided when the subscriber requests a roaming service, and thus a roaming service between networks can be quickly provided without delays.
Claims14
A first broadcast subscription management (BSM) entity configured to communicate with a terminal via a network, comprising:
- a receiver;
- a transmitter;
- and
- a processor connected to the receiver and transmitter, the processor configured to:
- receive, from the terminal, a service request message, wherein the service request message comprises first information related to a second BSM entity, and wherein the service request message further comprises at least one of a user identification and a device identification,
- send, to the second BSM entity based on the first information related to the second BSM entity included in the service request message, a roaming service request message including second information about the second BSM entity, and the user identification, the second information including service provider information,
- receive, from the second BSM entity, a roaming service response message including a global status code in response to the roaming service request message, wherein if the roaming service fails, the global status code indicates that a service provider identification having been provided to the second BSM entity is unknown, that a BSM identification having been provided to the second BSM entity is unknown, or that an authorization of the device or the user failed, and
- send, to the terminal, a response message in response to the service request message, the response message including the global status code.
A second broadcast subscription management (BSM) entity configured to communicate with a terminal via a first BSM entity, the terminal configured to send a service request message to the first BSM entity that includes first information related to the second BSM entity, and at least one of an user identification and a device identification, the second BSM entity comprising:
- a receiver;
- a transmitter;
- and
- a processor operatively connected to the receiver and transmitter, the processor configured to:
- receive, from the first BSM entity, a roaming service request message including first information about the second BSM entity, and the user identification, the first information including service provider information, and
- send, to the first BSM entity, a roaming service response message including a global status code in response to the roaming service request message,
- wherein if the roaming service fails, the global status code indicates that a service provider identification having been received is unknown, that a BSM identification having been received is unknown, or that an authorization of the device or the user failed.
