Method, communication apparatus and system for handling a recharge service

A communication apparatus, comprising:

• an information interaction module and a first query module;
• the information interaction module is configured to receive a recharge service request which includes a recharge card ID and a user account to be recharged;
• and the information interaction module is further configured to request a voucher center to authenticate the recharge card, according to a query result obtained by the first query module, if the recharge card ID carried in the recharge service request is not contained in an abnormal recharge log, or a recharging process has not been successfully performed via the recharge card associated with the recharge card ID, so that the voucher center may recharge the user account via the recharge card after the recharge card passes the authentication;
• the first query module is configured to check whether the abnormal recharge log includes the recharge card ID and the recharging process has been successfully performed via the recharge card associated with the recharge card ID,
• wherein the abnormal recharge log is logged by an online charging system (OCS) when receiving an instruction from the communication apparatus, when the communication apparatus fails to receive an acknowledgement indicating a successful recharge from the OCS within a predetermined time period after the communication apparatus sends a recharge request or when the OCS fails to generate or send the acknowledgement indicating the successful recharge, and the abnormal recharge log includes recharge result information indicating whether a recharging process has been successfully performed in the OCS and recharge ID corresponding to the recharge result information.

An online charging system (OCS), comprising:

• a first receiving module, configured to receive a recharge request for recharging a user account sent by a service control point, wherein the recharge request includes a recharge card ID and the user account to be recharged;
• and further configured to receive a recharge confirmation request sent by the service control point;
• a recharge module, configured to recharge the user account via the recharge card and generate an acknowledgement indicating a successful recharge when the first receiving module receives the recharge request, and configured to complete the recharge and generate a recharge confirmation result when the first receiving module receives the recharge confirmation request, wherein the recharge confirmation result comprises recharge time and recharge amount;
• a first sending module, configured to send the acknowledgement indicating the successful recharge to the service control point after the recharge module recharges the user account and configured to send the recharge confirmation result to the service control point;
• and
• a write-in module, configured to record in an abnormal recharge log the recharge card ID and recharge result information indicating whether a recharging process has been successfully performed via the recharge card associated with the recharge card ID when one of the following conditions is met:
• (1) the write-in module receives a write-in notification sent by the service control point when the service control point fails to receive the acknowledgement indicating the successful recharge from the OCS within a predetermined time period after the recharge request is sent;
• (2) the recharge module fails to generate the acknowledgement indicating the successful recharge;
• and
• (3) the first sending module fails to send the acknowledgement indicating the successful recharge.
