Method and apparatus for supproting RCS auto-configuration
The disclosure relates to a method for supporting rich communication service (RCS) auto-configuration failure. The method includes: monitoring a plurality of messages exchanged between a user device and a configuration server, detecting a first message received from the configuration server is a failure message, extracting a timer from header of the failure message and a rate limiting factor of service provider from one or more databases, setting an alarm in the user device for sending a second message to the configuration server, storing configuration information including the timer and the rate limiting factor into a SIM memory, retrieving the stored configuration information from the SIM memory with reference to a requesting mode, and configuring the user device to send a third message to the configuration server based on the retrieved configuration information.
1 . A method for supporting, by a user device, rich communication service (RCS) auto-configuration, the method comprising:
sending, from a subscriber identity module (SIM), a first request message for RCS auto-configuration to a configuration server;
receiving a failure message for the RCS auto-configuration from the configuration server;
obtaining a timer from a header of the failure message and a rate limiting factor of service provider from one or more databases;
storing the timer and the rate limiting factor in a memory of the SIM,
wherein the timer and the rate limiting factor stored in the memory of the SIM is used for restricting transmission of a second request message for the RCS auto-configuration from the SIM to the configuration server in case that the SIM is installed on another device different from the user device; and
restricting sending of a message to the configuration server based on a count of the rate limiting factor exceeding a limit of retrial obtained from the one or more databases.
2 . The method of claim 1 , wherein the first request message and the second request message include HTTP or HTTPS request messages.
3 . The method of claim 1 , wherein the failure message includes an HTTP or HTTPS response message.
4 . The method of claim 1 , further comprising retrieving a retrial attempt parameter including the timer and count of the rate limiting factor from the memory of the SIM in a requesting mode, and sending the parameter.
5 . The method of claim 4 , wherein the requesting mode includes one of a primary device, a secondary device, and a changed device.
6 . The method of claim 1 , wherein the count of the rate limiting factor is stored in the memory of the SIM.
7 . The method of claim 1 , wherein the timer includes a retry after timer provided by the configuration server, the one or more databases include a service provider database, and the rate limiting factor includes limit of retrial provided by the service provider.
8 . A user device for supporting rich communication service (RCS) auto-configuration, the user device comprising:
memory storing instructions; and
at least one processor, wherein the instructions, when executed by the at least one processor, cause the user device to perform operations, wherein the operations comprise:
sending, from a subscriber identity module (SIM), a first request message for RCS auto-configuration to a configuration server,
receiving a failure message for the RCS auto-configuration from the configuration server,
obtaining a timer from a header of the failure message and a rate limiting factor of service provider from one or more databases,
storing the timer and the rate limiting factor in a memory of the SIM,
wherein the timer and the rate limiting factor stored in the memory of the SIM is used for restricting transmission of a second request message for the RCS auto-configuration from the SIM to the configuration server in case that the SIM is installed on another device different from the user device, and
restricting sending of a message to the configuration server based on a count of the rate limiting factor exceeding a limit of retrial obtained from the one or more databases.
9 . The user device of claim 8 , wherein the first request message and the second request message s include HTTP or HTTPS request messages.
10 . The user device of claim 8 , wherein the operations further comprise retrieving a retrial attempt parameter including the timer and count of the rate limiting factor from the memory of the SIM in a requesting mode, and sending the parameter.
11 . The user device of claim 10 , wherein the requesting mode includes one of a primary device, a secondary device, and a changed device.
12 . The user device of claim 8 , wherein the count of the rate limiting factor is stored in the memory of the SIM.
13 . The user device of claim 8 , wherein the timer includes a retry after timer provided by the configuration server, the one or more databases include a service provider database, and the rate limiting factor includes limit of retrial provided by the service provider.
14 . A non-transitory computer readable storage medium storing instructions, which, when executed by at least one processor of a user device, cause the user device to perform operations comprising:
sending, from a subscriber identity module (SIM), a first request message for RCS auto-configuration to a configuration server;
receiving a failure message for the RCS auto-configuration from the configuration server;
obtaining a timer from a header of the failure message and a rate limiting factor of service provider from one or more databases;
storing the timer and the rate limiting factor in a memory of the SIM,
wherein the timer and the rate limiting factor stored in the memory of the SIM is used for restricting transmission of a second request message for the RCS auto-configuration from the SIM to the configuration server in case that the SIM is installed on another device different from the user device; and
restricting sending of a message to the configuration server based on a count of the rate limiting factor exceeding a limit of retrial obtained from the one or more databases.
