Description

Territory of invention

The present invention relates generally relates to the provision of a service for network terminals in one Telecommunication network and in particular to a method for implementation a short message service with an intelligent network in one Mobile communication network.

background the invention

The mutual connection of one Mobile communication network and an intelligent network forms one intelligent mobile network, which is a network architecture, the new one Services in a mobile communication network effective, economical and conveniently generated and provided. From many telecommunications operators and standards organizations are different solutions to connect one Mobile network and an intelligent network have been proposed. The European Telecommunications Standardization Institute (ETSI = European Telecommunication Standard Institute) has the logic for improvement in 1997 mobile customer-oriented applications (CAMEL = Customized Application Mobile Enhancement Logic). The CAMEL provides for network service providers a mechanism that in turn is not one for the participant standard GSM service provides. If a participant moves away from their hometown, the same service is available as in his home area. On intelligent mobile network that implements the CAMEL service does not contain only the entities Home location register (HLR), location register (VLR = Visiting Location Register), mobile switching center (MSC = Mobile Switching Center) and gateway mobile switching center (GMSC = Gateway Mobile Switching Center), but also new ones functional entities of an intelligent network: service switching function unit (SSF = Service Switching Function) and GSM service control functional unit (gsmSCF = GSM Service Control Function).

HLR and gsmSCF form a home network, represents the subscriber home characteristics. For a mobile subscriber, who represents a called party in a call GMSC and SSF a query network while for one mobile subscriber who is a calling subscriber in a call is, MSC / VLR / SSF form a visiting network. communication protocols between each of the functional entities are the customer-oriented section Applications (CAP = Customized Application Part) and the section for mobile Applications (MAP = Mobile Application Part) of the CAMEL. The CAP protocol is between the functional entities SSF and gsmSCF used.

The PHASE 3 of the GSM CAMEL by ETSI has been proposed in the specification (23.078V4.0 above) relating to sending a short message to the mobile station of a recipient like a handset and developed for CAMEL PHASE 4 by 3GBP services, such as authentication, that defines Account assignment and the like. However, this mechanism can Forwarding a short message service for mobile devices (MT-SMS FORWARDING = Not implement Mobile Terminal Short Message Service Forwarding), so that the subscriber does not send a received short message to one forward to another handset or to a medium such as EMAIL can. Hence the flexibility a short message application will continue to function highly limited.

The aim of the invention is to create a method for implementing a new short message service in an intelligent mobile network. The method implements short message forwarding for a mobile terminal (receiver) in order to improve the short message service function and flexibility. The invention provides a method for implementing a short message service in an intelligent mobile network, which includes at least one service switching function entity (SSF entity) and one mobile service control function entity (gsmSCF entity), among which the service switching function entity is a connection point between the intelligent network system and the mobile communication system. The method comprises at least the following steps:

• a. after the SSF has captured a short message service request, it forwards the request to the gsmSCF;
• b. The gsmSCF queries the subscriber corresponding to the destination address of the request in a database to find out whether it is a short message call forwarding request, to proceed to step c in the positive case and otherwise to send the short message to the destination station and to end;
• c. the gsmSCF starts a receive end short message forwarding service logic to affect SSF call processing: the short message sent to a target station is forwarded to a mobile station or a medium designated by the target station. Step c in the above process also includes ner:
• c1. In operation, two selectable parameters, namely the destination subscriber number and the short message service center address (SMSC address), are added to the Connect SMS message sent by the gsmSCF to the SSF;
• c2. The gsmSCF receives data: either the target subscriber number or the SMSC address;
• c3. after the receiving end gsmSCF receives the short message request message proposed by the SSF at the receiving end, the gsmSCF starts the receiving end short message forwarding service logic, wherein the called number or the SMSC address corresponding to the called mobile station address in the message is sent back to the SSF;
• c4. After the SSF has received, a short message is sent to the target subscriber number or the SMSC address.

This parameter setting and the short message forwarding service logic at the receiving end in the service generation environment (SCE = Service Creation Environment) and generated by the service management system (SMS = Service Management System) loaded into the gsmSCF.

In the above solution, the SSF can be in the mobile switching center (MSC) or in the service GPRS support node (SGSN = Service GPRS Supporting Node) can be set, but it can also be set independently become. The SS7 signaling is used for communication between the SSF and the gsmSCF are used.

Step c2 further includes: the Mobile station sends a short message that the destination subscriber address contains to the local SMSC; then the local SMSC forwards the message the gsmSCF further; therefore the gsmSCF the target participant number and saves them in a database.

The destination subscriber number or SMSC address can and will be set directly on the gsmSCF operating console stored in a database. The target subscriber number can be one Mobile station number or a specific subscriber number, the one Email address corresponds to.

The created by the invention Procedure for a short message service in an intelligent mobile network implement short message forwarding. The process improved not just flexibility of the short message service and creates not only convenience for mobile communication subscribers, but also it has for the telecommunications operator the advantage of more telephone traffic attract and increase profit.

embodiments the invention

The present invention is described in Following with reference to the accompanying drawings and to embodiments described in more detail.

In 1 HLR is usually a database that stores all home subscriber data and all dynamic home subscriber data. It provides data from mobile subscribers to the VLR.

The message traffic between the VLR and the MSC is extremely high, so they are usually called physical units be set. MSC / VLR runs one Call switching off, controls the mobile station location update and handover between cells.

The mobile network service switching functional unit (gsmSSF) is a functional entity attached to the MSC and is a kind of SSF. As an interface between MSC / VLR and the gsmSCF is for you the transformation of call status information provided by the MSC will be reported and sent to the gsmSCF. She receives Moreover gsmSCF commands and transforms their format to then convert them to the Send MSC. The gsmSSF can either be in the MSC or independently be constructed.

The gsmSCF is a unit of one dynamic database and service processing and controls in Within their responsibility for the implementation of the CAMEL service logic and the special service Call forwarding, account assignment and the like.

2 Figure 3 is an intelligent mobile network architecture that implements short message service and consists of a service switching point (SSP), a service control point (SCP), an intelligent peripheral (IP), a service management system (SMS), a service generation environment (SCE), and the like.

In 2 SSP (Service Switching Point) is a physical entity corresponding to SSF that performs the same functions as the SSF: detecting a service request, communicating with the SCP, responding to an SCP request, and allowing service logic in the SCP to affect call processing.

The SCP (service control point) is one gsmSCF corresponding physical entity that has the same functions as the gsmSCF explains: Receiving query information and querying a database as well To run different decodings. At the same time, the SCP starts with regard different on the implementation of different smart calls Service logic according to the calls proposed by the SSP and sends in accordance with the service logic a call control command to a corresponding one SSP off.

The IP (intelligent peripheral device) is a special resource that the execution of the intelligent service supports and ordinary various language functions such as speech synthesis and broadcasting has recorded notes and the like. The IP can independent physical device or be part of the SSP. The IP is defined by the SCP Operations out.

The SMS (service management system) is also a computer system. In general, SMS has five functions: Service logic management, service data management, subscriber data as well as service monitoring and traffic management. A new service that is in the service creation environment is generated, is entered into the SMS by the service provider, whereupon the SMS loads the new service into the SCP and then the new service is provided in a telecommunications network.

The SCE (service creation environment) creates a new service logic according to the subscriber request. The SCE provides an editor with a user-friendly graphics interface for the Service design engineer ready. The customer uses different ones Standard graphic elements to the service logic of a new service to design and define corresponding data.

Communication protocols for the above Units are the following: TCP / IP between SCE and SMS, SMAP and SMS are in a wide area network or in a local area network interconnected, SMS and SCP are in a wide area network or connected in a local network and SS7 carries out the Signaling between SCP and SSP off.

The following is an embodiment described the invention in detail.

The service logic and the service data, that are required by the short message forwarding are in the SCE generates, whereupon a service logic module is formed. The generated Receive end short message forwarding service logic is validated and tested. Here, the so-called service logic is a service procedure, while the so-called service data are data and parameters that are used during the execution the service procedure can be used. Among them are two selectable parameters, namely the destination subscriber number and the SMSC address for the company message Connect SMS sent from the SCP to the SSP added. table 1 shows the original Message format and its definition, while Table 2 the updated Message format and its definition shows.

Tabelle 1: Format und Definition der ursprünglichen Nachricht

Table 1: Format and definition of the original message

Tabelle 2: Format und Definition der aktualisierten Nachricht

Table 2: Format and definition of the updated message

In Table 1 and Table 2, "O" represents that the characteristic is "selectable", while "-" means that the characteristic does not exist is.

The SMS loads the receiving end short message forwarding service logic and the service data in the SCP, so that a software module in the SCP a short message forwarding is generated. Then if the receiving end short message forwarding service procedure works, monitors the SMS the execution situation and generates its statistics and reports. If the logic is not necessary is deleted from the intelligent network.

If a called mobile subscriber a short message that is sent to his mobile station want to forward another mobile station or to an email box this by sending a short message which is the mobile station number or contains the email address, to the local SMSC. Then the SMSC forwards the message to the local SCP, the SCP providing the destination subscriber number service data receives and stores them in a database. Alternatively, if the SCP all Short subscriber messages assigned to him to an SMSC for one Want to forward processing, can do this despite the specification of a mobile subscriber by setting the SMC address on the SCP control panel and by storing the SMSC address happen in a database.

If there is an SSP at the receiving end Short message for the SCP suggests at the receiving end, the SCP immediately starts the short message service logic at the receiving end, if the short message is a short message to be forwarded, and directs a destination subscriber address or an SMSC address the SSP back at the end of the transmission. This affects the processing flow of the SSP at the end of transmission, such that he sent the short message to a last mobile station, to an email box or forwarded to a short message center.

• 1) Wenn ein anrufender Teilnehmer eine Kurznachricht an eine Mobilstation MS1 senden möchte, schlägt ein SSP dann, wenn er den Teilnehmer, der eine Kurznachrichtanforderung sendet, erfasst, diese Anforderung sofort der gsmSCF vor, d. h. der SSP sendet eine Initialisierungserfassungsnachricht INIT DP, die die Adresse MS1 enthält, an T-SCP. In dieser Ausführungsform wird die SSP in der T-MSC der SMSC gesetzt.
• 2) Nachdem die gsmSCF die Nachricht empfangen hat, fragt sie in einer Datenbank an, ob der Teilnehmer eine Kurznachrichtweiterleitungsanforderung ausgegeben hat, wobei sie im positiven Fall, d. h., wenn die angerufene Mobilstation MS1 die Nachricht an die Mobilstation MS2 weiterleiten möchte, die Kurznachrichtweiterleitungsdienstlogik am Empfangsende startet und den T-SCP über die Kurznachrichtweiterleitung informiert. Dann sendet der T-SCP eine Betriebsnachricht Connect SMS an die T-MSC (SSP), die den SSP über die Aktualisierung der Zieladresse von MS1 zu MS2 informiert. Andernfalls wird die Kurznachricht direkt zur Mobilstation MS1 gesendet.
• 3) Danach sendet die T-MSC (der SSP) direkt eine Weiterleitungskurznachrichtdienstnachricht (FORWARD SMS), wobei der Inhalt der Kurznachricht an die MS2 weitergeleitet wird.

3 shows a simple call signaling a short message forwarding. In 3 and in 4 the short message forwarding procedure comprises at least the following steps:

• 1) If a calling subscriber wants to send a short message to a mobile station MS1, an SSP, when it detects the subscriber who sends a short message request, immediately proposes this request to the gsmSCF, that is to say the SSP sends an initialization detection message INIT DP, which the Contains address MS1 at T-SCP. In this embodiment, the SSP is set in the T-MSC of the SMSC.
• 2) After the gsmSCF has received the message, it inquires in a database whether the subscriber has issued a short message forwarding request, and in the positive case, that is to say if the called mobile station MS1 wants to forward the message to the mobile station MS2, the short message forwarding service logic on The end of reception starts and the T-SCP is informed of the short message forwarding. The T-SCP then sends an operating message Connect SMS to the T-MSC (SSP), which informs the SSP of the update of the destination address from MS1 to MS2. Otherwise the short message is sent directly to the mobile station MS1.
• 3) The T-MSC (the SSP) then sends a forwarding short message service message (FORWARD SMS) directly, the content of the short message being forwarded to the MS2.

The above is just a perfect embodiment of the invention explained The scope of the invention in no way thereby limited shall be.

Summary

The invention discloses a method for implementing a short message service in an intelligent mobile network, which comprises at least one service control function entity (gsmSCF) and one service switching function entity (SSF). The service switching function entity is a connection point between the intelligent network system and a mobile communication network system. If SSF has detected a short message service request, this gsmSCF is proposed. The gsmSCF then queries a database to determine whether there is a short message call forwarding request for the target subscriber that corresponds to the target address of the short message. If not, the short message is sent to the target mobile station. If so, the gsmSCF starts the short message forwarding service logic at the receiving end to influence the SSF call processing: forward the short message that was originally sent to the mobile station to the other mobile station or to an information medium. The application of the invention not only improves the flexibility of the short message service and not only increases the convenience for the mobile communication subscriber, but it also has the advantage that the service operator can attract more traffic and increase the profit.
