Description

METHOD AND MEANS FOR HANDLING MULTIPLE SERVICES OF AN INTELLIGENT NETWORK WITHIN A MOBILE COMMUNICATION
NETWORK
The present invention relates to a method and apparatus means for handling multiple services of an intelligent network within a mobile communication network according to the independent claims.
BACKROUND OF INVENTION
This invention is particularly used in the environment of a GSM or UMTS mobile communication network.
According to the architecture of Intelligent Networks (IN) there are Call Control Functions (CCF) defined in the Service Switching Point (SSP) which is associated with a Switching System, particularly a Mobile Switching Center (MSC) . Call Control Functions are standardised for triggering IN services. Socalled Trigger Detection Points (TDP) are defined. TDP1 means "Orig_Attempt_Authorized" concerning e.g. Off-Hook (emergency call or baby phone) which is normally not used in the mobile communication field. TDP2 means "Collect_Information" concerning the origination parts of e.g. the Prepaid (PPS) service or the Virtual private network (VPN) service. TDP12 means *Terminating_Attempt_Authorised" concerning the terminating parts of e.g. the Prepaid (PPS) service or the Virtual private network (VPN) service. TDP3 means "Analyzed_Information" concerning e.g. Free Number or direct dialled services.
Using the CAMEL (Customized Applications for Mobile Network Enhanced Logic) standard, which is the feature in the GSM standard to provide support for operator-specified services even for international roaming and to integrate IN features into the GSM architecture, it is not possible to trigger more than one originating or more than two terminating IN services (one in the Gateway MSC and one in the Visited MSC) for the same subscriber. That means that a prepaid subscriber cannot subscribe another originating service. Especially with the new idea of third party applications there is a growing interest in being able to trigger several different originating services during one call. Also with the idea to introduce the service Virtual Private Network (VPN) as a mass service, there is the problem that Prepaid Service (PPS) and VPN cannot be triggered with CAMEL originating triggers for one and the same subscriber. The same problem occurs for the terminating service trigger, however due to the introduction of the Visited T-CSI, triggered in the VMSC, the situation is not so restricting.
Up to now the problem for the originating trigger was solved by abusing the dialled trigger: The first service is triggered at the Trigger Detection Point "DP_COLLECTED_INFORMATION" as it should be according to the standard using an originating CSI (O-CSI) . Then a certain prefix, added to the destination routing address (by the MSC) , or some other criteria leads to a dialled IN trigger for the second service. That means that the trigger detection point for the second service is not " DP_COLLECTED_INFO" (TDP2) but "DP_ANALYSED_INFORMATION" (TDP3) . This again causes problems with the information, which is sent to the SCP (Service Control Point) in the operation InitialDetectionPoint . The information for TDP2 is different to the information sent in case of TDP3.
SUMMARY OF INVENTION
The present invention aims to develop methods and apparatus means which allow triggering multiple IN services following the CAMEL standardised method. Said problem is solved by the features mentioned in the independent claims. Preferred embodiments of the invention are described in the dependant claims.
An aspect of the invention is to introduce more than one trigger detection point.
According to the CAMEL standard REL 5 the Originating Subscription Information (O-CSI) looks like in the following way:

The proposed invention provides the following advantages:
The existing definition of the CAMEL Subscription Information and the existing trigger mechanism in the CAMEL standard is enhanced. It is possible to trigger not only one originating and/or two terminating services per call, but several in a CAMEL environment, i.e. in GSM and UMTS networks with IN. The result is a more flexible combination of different services. Together with an already implemented mechanism, which allows the different services to exchange information in forward as well as in backward direction for correlation purposes, this will be a powerful concept for a future MSC.
BRIEF DESCRIPTION OF THE DRAWINGS
Preferred embodiments of the present invention will now be described with reference to the accompanying drawing in which:
Figure 1 is a schematic diagram of a part of a GSM or UMTS mobile communication network in which the present invention can be used, if multiple Trigger Detection Points are statically activated in case of an originating call.
Figure 2 is a schematic diagram of a part of a GSM or UMTS mobile communication network in which the present invention can be used, if multiple Event Detection Points (EDP) are dynamically activated during active IN dialogue in case of an originating call.
Figure 3 is a schematic diagram of a part of a GSM or UMTS mobile communication network in which the present invention can be used, if multiple Trigger Detection Points are statically activated in case of a terminating call.
Figure 4 is a schematic diagram of a part of a GSM or UMTS mobile communication network in which the present invention can be used, if multiple Event Detection Points (EDP) are dynamically activated during active IN dialogue in case of a terminating call.
DETAILLED DESCRIPTION OF THE DRAWINGS
The figures generally depict a part of a GSM or UMTS mobile communication network, wherein it is shown several network elements like a mobile phone XY, a Mobile Switching Centre MSC, several Service Control Points SCP and a Home Location Register HLR. The message flow of figure 1 and 3 describes the normal Situation, if multiple Trigger Detection Points are activated. The message flow of figure 2 and 4 concerns an extension of the "normal Situation", if multiple Event Detection Points are activated. The mentioned and shown messages flow among the network elements according to the numbering.
The handling is rather simple: the shown O-CSI is treated as before. During location update it is sent to not shown the Visited Location Register VLR, whose content is similar to the content of the shown Home Location Register HLR. It is sent from the Home Location Register HLR to the Mobile Switching Centre MSC during the interrogation, if there is call forwarding active or if a T-CSI is subscribed too and it is sent from the HLR to the Service Control Point SCP in case of Any Time Subscription Interrogation.
If in case of a mobile originating call or in case of call forwarding a TDP2 "DP_Collected_Info" is triggered and if there are multiple TDP2's - depicted as TDP2_1, TDP2_2, TDP2_3, possibly being more than shown - the DP_Collected_Info_l is triggered at first. Any information, which is modified by the SCP during this IN dialogue shall be stored and shall be taken into consideration when the next originating service is triggered. If different originating services (SKI, SK2 and SK3) have armed one and the same Event Detection Point (EDP), e.g. the EDP *Answer" (2 from SKI, 5 from SK2, 8 from SK3) and if this EDP is met (11), then the service, which was triggered as last shall be informed first (13 to SK3, 15 to SK2, 17 to
SKI) . Any modification shall be taken into consideration when passing the EDP backwards. I.e. if SCP 3 modifies the information, which it received with the ERB Answer (12) and sends this information to the MSC in the message CWA (13) , the MSC will provide the modified information to SCP 2 in the message ERB Answer (14) .
Concerning a mobile terminating call the above described message flow could be employed in an analogue manner.
The handling is rather simple: the T-CSI is treated as before, it is stored in the HLR and it is sent from the Home Location Register (HLR) to the Mobile Switching Centre (MSC) during the interrogation and from the HLR to the Service Control Point (SCP) in case of Any Time Subscription Interrogation.
If in case of a mobile terminating call a TDP12 ,vDP_Terminating_Attempt_Authorised" is triggered in the GMSC and if there are multiple TDP12s, the "DP
Terminating_Attempt_Authorisedl" is triggered at first. Any information, which is modified by the SCP during this IN dialogue shall be stored and shall be taken into consideration when the next terminating service is triggered.
If different terminating services (SKI, SK2 and SK3) have armed one and the same Event Detection Point (EDP), e.g. the EDP *Answer" (2 from SKI, 5 from SK2, 8 from SK3) and if this EDP is met (11), then the service, which was triggered as last shall be informed at first (13 to SK3, 15 to SK2, 17 to SKI) . Any modification shall be taken into consideration when passing the EDP backwards. The following applications of the invention are imaginable:
If VPN (Virtual Private Network) shall become a mass service, i.e. if friends and families can build small VPNs, the PPS service, which is a mass service too must interwork with VPN. If additionally MNP (Mobile Number Portability) has to be offered, this three originating dialogues can be handled easily with the new concept.
The regulation body has forced the introduction of Mobile Number Portability (MNP) . It must be possible, to change the operator while keeping the MSISDN for a subscriber. As the tariff for Mobile Originating Calls (MOC) is less for subscribers of one and same network, the prepaid service must know, to which network the B subscriber belongs. Thus there must be a MNP dialogue before the PPS dialogue. If there is a VPN subscriber, the VPN dialogue must be triggered before the MNP dialogue, because the MNP dialogue needs the long number. If all three services are subscribed by one mobile subscriber service triggering becomes really difficult. But this is what the operator wants to do in future!
If the operators want to introduce third party services (located inside or outside the networks trusted domain) these services must be triggered. The order of the triggering of the third party application service and PPS, MNP and/or VPN service will depend on the kind of service. To be flexible, the originating services may all be triggered via O-CSI and the order may depend on the numbering of the defined TDPs. ABBREVATIONS
