Abstract
The present invention deals with a method and system for routing a call in a mobile communication network. The method comprises receiving a message by a caller prevailing network corresponding to a caller from a callee home network corresponding to a callee, if the callee is roaming. The message is received in response to the call being initiated by the caller for the callee. The message can comprise a redirection information corresponding to the callee in roaming. The method further comprises solving a predefined criterion for routing the call based on the redirection information in the message and connecting the call based on solution of the predefined criterion.
Claims19
A method for routing a call in a mobile communication network, the method comprising:
- receiving a message by a caller prevailing network corresponding to a caller from a callee home network corresponding to a callee, if the callee is roaming, wherein the message is received in response to the call initiated by the caller for the callee, wherein the message comprises a redirection information corresponding to the callee in roaming;
- solving a predefined criterion for routing the call, wherein the predefined criterion is solved based on the redirection information in the message;
- and
- connecting the call based on solution of the predefined criterion.
A method for minimizing cost of a call in roaming in a mobile communication network, the method comprising:
- receiving a message by a caller prevailing network corresponding to a caller from a callee home network corresponding to a callee, if the callee is roaming, wherein the message is received in response to the call initiated by the caller for the callee, wherein the message comprises redirection information corresponding to the callee in roaming;
- calculating a first cost and a second cost, wherein the first cost corresponds to routing the call to the callee visited network from the caller prevailing network based on the information in the message, the second cost corresponds to routing the call to the callee visited network from the caller prevailing network through the callee home network;
- comparing the first cost with the second cost;
- and
- connecting the call based on comparison of the first cost and the second cost.
A system for routing a call in a mobile communication network, the system comprising:
- a messaging sub-module, wherein the messaging sub-module sends a message from a callee home network corresponding to the callee, if the callee is roaming, the message is sent in response to the call initiated by a caller, wherein the message comprises redirection information corresponding to the callee in roaming;
- and
- a routing-rule module, wherein the routing-rule module solves a predefined criterion for routing the call, the predefined criterion is solved based on the redirection information in the message.
