The present invention relates to an object model of a persistent object, and more particularly, to an object model of a persistent object of a cellular paging short service.

In general, the cellular paging short service is a service for transferring a string of up to 63 octets in size in the form of a message between short message entities.

The cellular paging short message service basically provides a short message transmission / reception service for subscribers of digital mobile communication network and supports the store-forward function which is a non-real time message forwarding characteristic.

If the incoming short message entity is in a state such as a power off, the text message is stored in the cellular paging short service center, and when it is recognized as possible, the message is sent directly to the incoming short message entity.

Conventionally, since most communication service development methods are based on structural techniques, there is a problem in that cumbersome work of changing a model is required every time a new function is added.

The present invention for solving the above problems is to provide an object model of a persistent object that can minimize the change of the model when adding a new function by constructing an object model based on the object-oriented methodology.

A feature of the present invention for achieving the above object is that the object model of the persistent object composed of the object class in the cellular paging short service that delivers a string of up to 63 octets in the form of a message between the short message entities in the CDMA mobile communication system In this case, the first class having the information of the address type and the address and the subaddress, all attributes of the first class are inherited, and the first subclass, which is the originating short message entity, and all the attributes of the first class. A second subclass, which is a receiving and receiving short message entity, a third subclass inheriting all the attributes of the first class, a second class having information on pointer addresses and node identifiers, a message identifier and a user for identifying a message. Priority indicator to indicate user data and transmission priority, including text messages from A third class with personal indicators for security management of characters and text messages and response choices for acknowledgment of outgoing text messages; a fourth class with message identifiers and text response codes for responses to user data and text message delivery. And a fifth class having a message identifier and user data.

In order to manage a text message that cannot be sent to an incoming short message entity in a database, the persistent objects of the managed cellular paging short service are extracted and the object model for the extracted objects is described. Hereinafter, with reference to the accompanying drawings will be described in detail one of the preferred embodiments according to the present invention.

1 is a structural diagram of a cellular paging short service center to which the present invention is applied.

Referring to Figure 1 describes the structure of a cellular paging short message service center to which the present invention is applied.

The cellular paging short message service center 100 includes a communication network management subsystem 101, an operation management subsystem 102, a management information base 103, a persistent object database 104 of the cellular paging short service, and an operation management database 105. ), The cellular paging application service subsystem 106, the signal matching subsystem 107, the call control subsystem 108, and the service provider matching subsystem 109.

The communication network management sub-system 101 has a communication network management agent function for the operation center and manages the management information base 103.

The operation management sub-system 102 performs functions such as collecting short service billing, statistical processing of the cellular paging short service center 100, graphic operator matching, short service information processing and management, and for this, operation management database 105 ).

The cellular paging application service subsystem 106 supports the functionality of storing and managing problem messages as well as controlling the short message services and manages the persistent object database 104 of the cellular paging short service to manage text messages.

The signal matching subsystem 107 performs common line signal processing, MAP (Mobile Application Part) signal processing, and teleservice layer protocol processing.

The call control subsystem 108 handles incoming calls of the fixed switching network short message entity through the mobile exchange, simulates incoming calls of the cellular paging short service center 100 for receiving DTMF (Dual Tome Multi Frequency) signals, and ARS. Control and so on.

The service provider matching subsystem 109 performs X.25 protocol processing and Transmission Control Protocol / Internet Protocol (TCP / IP) processing.

Objects managed by the persistent object database 104 are manipulated and operated by the application service subsystem 106.

2 is a diagram illustrating persistent objects of a cellular paging short service. Referring to FIG. 2, persistent objects of the cellular paging short service are described as follows.

The object classes shown in FIG. 2 represent persistent objects of the cellular paging short service considering only their characteristics without defining the relationships between the objects, and are object classes for persistent objects to be managed by the persistent object database 104. .

SME 210 inherits all the characteristics of SME 120, OrgSME 211, the originating short message entity, DesSME 211, DesSME 212, and CallBackNum 213, the incoming short message entity.

The SMSC 220 object class has IPAdress and Nodeldentifier as its attributes.

The CPT-SM 230 object class has a MessgaeIdentifier for identifying messages as its attributes, a UserData containing the user's text messages, a PriorityIndicator for indicating the transmission priority, a PrivacyIndicator for managing text message security, and ReplyOptions for response confirmation.

The Del-Ack-MSG 240 object class has as its attributes the MessageIdentifier, UserData and UserResponseCodes for responses to text message delivery.

The Del-Ack-MSG 250 object class has MessageIdentifier and UserData as its attributes.

3 illustrates the relationship of persistent objects of a cellular paging short service.

Referring to FIG. 3, the relationship between the object classes defined in FIG. 2 will be described as follows. The OrganizationSME 211 is a sender of the CPT-SM 230 and Del-Ack-MSG 240 and User-Ack-. Is the called party of MSG 250.

OrgSME 211 has a one-to-many relationship with CPT-SM 230, Del-Ack-MSG 240, and User-Ack-MSG 250.

The CPT-SM 230 has a CallBackNum 213, a text message is generated by the outgoing short message entity OrgSME 211, managed by the SMSC 220, and finally delivered to the incoming short message entity DesSME 212. Delivered.

The CPT-SM 230 has a one-to-one relationship with CallBackNum 213.

The Del-Ack-MSG 240 is generated and managed by the SMSC 220 and finally delivered to the OrgSME 211.

The SMSC 220 generates Del-Ack-MSG 240 objects created by itself, CMT-SM 230 objects created by the OrgSME 211, and User-Ack-MSG generated by the DesSME 212. (250) Manage objects.

SMSC 220 has a one-to-many relationship with CPT-SM 230, Del-Ack-MSG 240, and User-Ack-MSG 250.

The User-Ack-MSG 250 is generated by DesSME 212, managed by SMSC 220, and finally delivered to OrgSME 211.

DesSME 212 is in a one-to-many relationship with CPT-SM 230 and User-Ack-MSG 250.

The present invention proposes a method of managing persistent objects by calling party number, a method of managing by called party number, and a management method by SMSC 220 to manage persistent objects.

In the caller management method, when persistent objects that have been stored in the persistent object data base system 104 are retrieved and delivered to the called party normally, the sender management method needs to delete an object from the persistent object database 104.

Because caller numbers and message identifiers are used as keys to delete persistent objects, it is time consuming to retrieve those objects if persistent objects are managed by persistent object database 104 inconsistently. Therefore, persistent objects are managed by sender to retrieve and manage objects effectively.

In the receiver-specific management method, when the called party is changed from the unreceivable state to the receivable state, persistent objects, which are messages stored in the database 104 in the unreceivable state, should be retrieved and transmitted to the called party.

If persistent objects are managed by persistent object database 104 inconsistently, it is time consuming to retrieve those objects. Therefore, persistent objects are managed by called party QUF to retrieve and manage objects effectively.

Looking at the calling party number and the called party number for each persistent object, the calling party number of the CPT-SM 230 is OrgSME 211 and the called party number is DesSME 212.

The calling party number of the Del-Ack-MSG is SMSC 220 or DesSME 212 and the called party number is OrgSME 211.

The calling party number of the User-Ack-MSG is DesSME 212 and the called party number is OrgSME 211.

To access persistent objects, we use the logical product of the sender number and the message identifier as the delete key and the called party number as the search key.

The short service is a communication service provided based on a store-and-forward function, so that each persistent object is continuously transmitted to the called party when a large number of persistent objects that arrive at a particular called party exist in the persistent object database 104. Upon receiving a success response to the transmission, the application service subsystem 106 deletes the persistent object.

Thus, to identify a transport object to be deleted among a large number of persistent objects present in the persistent object database 104, a message identifier, a sender number and a series of numbers assigned by the sender, is required. And if a particular called party cannot receive the message, the application service subsystem 106 stores the persistent object, which is a message to be delivered to the called party, in the persistent object database 104.

In addition, when the called party is in a state capable of receiving a message, the application service subsystem 106 retrieves the persistent object, which is a message to be sent to the called party, from the persistent database 104 and transmits it to the called party.

Therefore, the called party number is used as the search key of the persistent object.

Therefore, the present invention as described above has an effect that the new function can be added freely with a minimum change of the model without having to change the model every time a new function is added.
