FIG. 1 is a block diagram illustrating a mobile communication system according to the 3GPP system. 1, in this mobile communication system, a plurality of radio network controllers (RNC) 7 and 9 are connected to a core network (CN) 3, and each RNC 7 and 9 is connected to a plurality of base stations (Node B) 13 to 16. In this case, the base stations 13 to 16 transmit the information received from the mobile station (UE) 5 to the RNCs 7 and 9 , while the information received from the RNCs 7 and 9 can be transmitted to the mobile station 5 . At this time, various interfaces and protocols may be employed in the mobile communication system to establish communication between communication devices. That is, the Iu interface is used between CN3 and RNCs 7 and 9, in this case using the Radio Access Network Application Part (RANAP) protocol. Similarly, there is an Iur interface and a Radio Network Subsystem Application Part (RNSAP) protocol between RNCs 7 and 9 that are different from each other, while a lub interface and a Node B Application Part (NBAP) protocol are used between RNC 7 and base station 9 . Therefore, each communication device can communicate in the mobile communication system by using the interface and the above-mentioned protocol. Here, UTRAN1 generally includes a plurality of RNCs 7 and 9 , a plurality of base stations 13 to 16 connected to RNCs 7 and 9 , and a base station manager (BSM) 11 . BSM11 generally has information such as PLD required in RNC7 and 9, and displays RNC and message results of each information. In addition, BSM11 can connect with up to 16 RNCs.

Meanwhile, in order to perform control functions such as communicating with other devices and managing its own resources, the RNCs 7 and 9 are equipped with various protocols including a radio resource control (RRC) layer, a radio link control (RLC) layer, and a medium access control ( MAC) layer.

In a mobile communication system, in case a paging message is received in RNCs 7 and 9, the paging message may be transmitted to each mobile station 5 according to a paging group including only an International Mobile Subscriber Identity (IMSI). In other words, there is a disadvantage that the paging group table to which the IMSI belongs must be searched every time because the paging group table is installed in the RNC in the relevant area. Thus, the IMSI may be a unique number assigned to each mobile station.

Therefore, if the RNC receives a paging message from the CN, the paging message can be sent to each mobile station by the paging group according to the type or purpose of the paging message, so as to increase the service selection provided for the user, and the mobile communication The system can prevent the load increase caused by the search delay, so that the user can quickly receive the paging message.

The method of sending paging messages received from the core network (CN) in the system according to the present invention is realized in the RNC in the narrow sense, and in the UTRAN including the BSM in the broad sense, in multiple base stations and implemented in the RNC.

The main idea of the present invention is a method of sending a paging message in a certain device, rather than a device implementing the method for sending the above paging message.

Referring to FIG. 2 , RNC21 is configured as a part of UTRAN1 in a mobile communication system including core network (CN) 3 , UTRAN1 and mobile station 5 . UTRAN1 includes two RNC7 and 9, a plurality of base stations 13 to 16 connected to RNC7 and 9, and BSM11 connected to RNC7 and 9 for providing information such as PLD and displaying information from RNC and other various information . In this respect, the method of sending paging messages according to the present invention is embodied by the RNC21 operating as an integral part of the present invention, and the BSM11 for providing the required information in response to RNC21's request. The RNC21 will be described in detail, but the description of the BSM11 will only be briefly introduced when necessary.

RNC21 comprises RANAP layer 23, is used for receiving paging message from CN3; And RRC layer 25, is used for confirming whether corresponding paging group information exists according to IMSI of paging message, searches information in paging group table according to the confirmed result , after a predetermined time elapses, extract the saved and/or updated IMSI according to the paging group in the paging group database 29, and send the extracted information and paging message to each mobile station 5 corresponding to the IMSI.

In particular, RNC21 can receive a paging message from CN3 as a higher layer using the RANAP protocol. Here, RANAP operating at the RANAP layer 23 is used for communication between CN3 and RNC21. Of course, RNC21 also involves the RNSAP protocol for communicating with other RNCs and the NBAP protocol for communicating with base stations, and other protocols will not be described in detail here, because they do not belong to the scope of the present invention to some extent. Incidentally, the paging message received by the RANAP protocol can be controlled by the RRC layer 25 so as to be sent to each mobile station 5 .

When the paging message is forwarded to the RANAP layer 23, the RRC layer 25 extracts the IMSI according to the result of analyzing the content of the paging message. Additionally, the RRC layer 25 queries the paging group table 27 to see if the IMSI exists in the table. If an IMSI corresponding to the IMSI exists in the table 27, the RRC layer 25 may update the paging group database 2 by using the paging group information. With reference to Fig. 3, table 27 includes IMSI field 31 and paging group field 33, and the special number of each mobile station is stored in IMSI field 31, and the paging group information corresponding to each special number is stored in paging group field 33 middle. In this case, paging group information is determined to easily control and/or manage paging messages in the paging group database 29, and can be classified into groups by their types and/or purposes.

As shown in FIG. 4, the paging group database 29 is formed as a database for managing paging messages by group, and the paging group database 29 can be updated to desired IMSIs and paging messages by group.

Therefore, if table 27 has an equal IMSI to one included in the paging message received from CN3, the paging group information corresponding to the IMSI represented in table 27 can be found from database 29, and the IMSI and paging The messages may be stored in a database 29 .

On the other hand, if the table 27 does not have the same IMSI as the IMSI contained in the paging message received from CN3, the RRC layer 25 instructs the BSM11 to get the information related to the IMSI and the paging group, and the received information can Stored in the paging group table 25 or used to update the paging group table 25.

Whenever a message is received from CN3, the RRC layer 25 determines whether the IMSI exists and then updates the paging message in the database 29 by group.

The RRC layer 25 can periodically extract the IMSI included in the group updated within a certain range from the group confirmation/identification database 29, and transmit the extracted information to each mobile station 5 together with a paging message.

Next, a method of transmitting a paging message in a mobile communication system according to the present invention will be explained with reference to FIG. 5. Referring to FIG.

First, in case of receiving a paging message from CN (step 51), the RRC layer analyzes the received paging message to extract the corresponding IMSI, and queries the paging group table to identify whether the IMSI exists (step 53). Here, the paging message can be received by using the RANAP protocol. Also, the IMSI and/or corresponding group information has been stored and established in the table. The corresponding group information is paging messages classified according to the type of the paging message or the purpose of the paging message.

As a result of the above confirmation operation, if the IMSI exists in the table, the RRC layer stores or updates in the paging group that has been converted into a database format in the database 29 according to the paging group information determined corresponding to the IMSI IMSI and paging message (step 57). At this time, the IMSI and paging group information contained in the table may be preset and stored when the RNC is started.

On the other hand, if the IMSI does not exist in the table, the RRC layer 25 instructs the BSM 11 to get the information related to the IMSA and the paging group, and the received information is stored in the paging group database.

Certainly, when the IMSI received from the BSM is the same as the IMSI included in the paging message received from the CN, step 57 is directly performed.

Through steps 51, 53, 55 and 57, whenever a paging message is received from the CN, the paging message can be updated in the paging group database.

The RRC layer periodically confirms/recognizes each group in the paging group database, and if the number of messages is more than a predetermined number, extracts each paging message contained in the corresponding group (step 59). In this case, the IMSI can be extracted simultaneously with the paging message. This extracted IMSI may be a unique number used to identify each mobile station when the extracted message is sent to each mobile station. The RRC layer may clear the IMSI corresponding to the IMSI delivering the paging message from the table.

As described above, the method for transmitting paging messages in a mobile communication system according to the present invention allows paging messages to be transmitted to desired mobile stations in groups according to their types and purposes. As a result, there is no need to search for the number of the IMSI in the paging table every time paging is performed, and thus an increase in load caused by a search delay can be prevented, whereby the user can quickly receive a paging message.

Although the present invention has been described with reference to specific embodiments, it will be understood that various changes in form and details may be made therein by persons skilled in the art without departing from the spirit and scope of the invention as defined by the appended claims. .
