| مستخلص: | A charging method for group main line, GML, service is disclosed. For an outgoing call from an extension of the GML, the initiated call is identified by adding a prefix for group service before the called number. When an intelligent network, IN, finds that there is the prefix for group service before the called number, the call is processed as collectively paid by the GML. A service control point, SCP, generates a call record for the call and places a special identification code in the call record. An incoming call redirected through the GML is also processed as collectively paid by the GML. The SCP generates a call record for the call and places a special identification code in the call record. The present invention also discloses a service control device. |

| Claim: | 1. A charging method for Group Main Line (GML) service, comprising: receiving a call initiated by an extension of the GML and triggering an Intelligent Network (IN) service; checking a called number of the call; processing the call initiated by the extension as a call collectively paid by the GML, if there is a predefined prefix for a group service before the called number, and processing the call initiated by the extension as a call not paid by the GML, if the predefined prefix for the group service is not present, wherein the step of processing the call initiated by the extension as the call collectively paid by the GML comprising: generating by a service control point (SCP), a call record for the extension which initiated the call, and indicating in the call record that the initiated call is paid by the GML; issuing by the SCP, a picking-call record instruction to an end office accessed by the extension; and marking by the end office, the call record for the extension recorded locally with a special charging flag, according to the picking-call record instruction. |
| Claim: | 2. The method of claim 1 , further comprising, triggering the IN service at a gateway office where the extension accesses a network, if the extension is a fixed extension; or triggering the IN service at the end office accessed by the extension, if the extension is a mobile extension. |
| Claim: | 3. The method of claim 1 , wherein the method further comprising: displaying the GML number at a caller ID display of the called party. |
| Claim: | 4. The method of claim 1 , wherein the method further comprising: processing the call as a non-GML call, if the IN finds that there is no predefined prefix for the group service before the called number. |
| Claim: | 5. A charging method for Group Main Line (GML) service, comprising: receiving a call to the GML and triggering an Intelligent Network (IN) service; redirecting the call to an extension of the GML according to a request from the calling party; checking, by a Service Control Point (SCP) of the extension, the calling number upon receiving an Initial Detection Point (IDP) message from a Service Switch Point (SSP) of the calling party; and processing, by the SCP of the extension, the call initiated by the extension as a call collectively paid by the GML, if there is a predefined special identification before the calling number and processing the call initiated by the extension as a call not paid by the GML, if a predefined prefix is not present, wherein the step of processing the call initiated by the extension as a call collectively paid by the GML comprising: generating, by the SCP of the extension, a call record for the extension, and indicating in the call record that the initiated call is paid by the GML; issuing, by the SCP of the extension, a picking-call record instruction to an end office which the extension visits; and marking, by the end office, the call record for the extension recorded locally with a special charging flag, according to the picking-call record instruction. |
| Claim: | 6. The method of claim 5 , wherein the step of redirecting the call to an extension of the GML according to a request from the calling party comprising: establishing, by the SCP of the GML, a temporary connection to an intelligent peripheral, IP; interacting, by the IP, with the calling party to obtain an extension number to which the calling party intends to be redirected; transmitting, by the IP, the extension number to the SCP of the GML; and transmitting, by the SCP of the GML, the extension number to the SSP of the calling party through a CONNECT message, and modifying the calling number in the CONNECT message and adding a special identification code before the calling number. |
| Claim: | 7. The method of claim 5 , wherein the method further comprising: displaying that the call is redirected by the GML at a caller ID display of the extension. |
| Claim: | 8. A service control device, comprising: a service logic unit which enables a corresponding service logic according to a call event reported by a Service Switch Point (SSP) and issue a call control instruction to the SSP according to the service logic; and a charging unit which charges a calling party or a called party in the call event and generates a call record; wherein the service control device further comprises: a called number checking unit which checks the called number in the call event, and informs the service logic unit to process the calling party as an extension collectively paid by the GML if there is a predefined prefix for a group service before the called number and to process the call initiated by the extension as a call not paid by the GML, if the predefined prefix is not present, wherein the service control device further comprises: a payment flag adding unit which adds a flag indicating that the call is paid by the GML to the call record generated by the charging unit for the calling party, when the called number checking unit finds that there is the predefined prefix for group service before the called number; and a picking-call record instruction issuing unit which issues a picking-call record instruction to an end office visited by the calling party instructing the end office to pick the call record of the calling party, when the called number checking unit finds that there is the predefined prefix for group service before the called number. |
| Claim: | 9. A service control device, comprising: a service logic unit which enables a corresponding service logic according to a call event reported by a Service Switch Point (SSP) and issues a call control instruction to the SSP according to the service logic; and a charging unit which charges a calling party or a called party in the call event and generates a call record; wherein the service control device further comprises: a calling number checking unit which checks an initial call message from an SSP of the calling party in the call event, and informs the service logic unit to process the called party as an extension collectively paid by the Group Main Line (GML) if there is a predefined special identification code before the calling number in the initial call message, and to process the call initiated by the extension as a call not paid by the GML, if a predefined prefix is not present, wherein the service control device further comprising: a payment flag adding unit which adds a flag indicating that the call is paid by the GML to the call record generated by the charging unit for the called party, when the calling number checking unit finds that there is the predefined special identification code before the calling number; and a picking-call record instruction issuing unit which issues a picking-call record instruction to an end office visited by the called party when the calling number checking unit finds that there is the predefined special identification code before the calling number. |
