Abstract

The address of a latest Serving GPRS support Node (SGSN) is provided to a Gateway GPRS Support Node (GGSN) by a special Update SGSN Address Request message which is sent from the SGSN to the GGSN. For a subscriber whose subscription permits, the address of the latest SGSN node is sent in the Update SGSN Address Request message for a qualified packet data protocol (PDP) context. A qualified PDP context (1) has a static PDP address; and (2) is not activated. The Update SGSN Address Request message can be sent from the SGSN to the GGSN in either a GPRS Attach scenario or an Inter-SGSN Routing Area Update Scenario. In response to the Update SGSN Address Request message, the GGSN sends an Update SGSN Address Response message which advises whether the updating of the address for the SGSN at the GGSN has been successful.

Description of the invention (2) The base station controller (B sc) in the child base station system (BSS) is connected to the core telecommunication network via the control node. A standard mobile telecommunication design type, for example, is used in Europe Global System for Mobile Communication (GSM) »The GSM includes standards for the development of various service functions and interfaces. The newer data service that can be used in the GS M system is the General Packet Radio Service (GPRS) ). GPRS differs from existing data services in that GPRS is a packet-switched data service rather than a circuit-switched data service.11 Among them (in GSM), a circuit-switched user is in a data call (for example, even when not sending data) Is continuously connected to the radio network; while GPRS users only need to (1) the mobile station wants to send or (2) the network has data to send to the bank The mobile station is connected to the radio network only. In other words, 'The mobile station in GPRS (for example, with the mobile version of the mobile phone) will not be continuously connected to the network when the computer is in use. These two sending events will only be connected to the network. An example of the GPrs system is shown in U.S. Patent Application Serial No. 09 / 069,969, filed on April 30, 1998 and named " Dynamic Allocation Packet Data Channels "application; and the US Patent Application No. 09 /-,-*, which was filed on April 30, 1998 AD, and the application whose name is " Allocation of Channels for Packet Data Services "; this The second application will be incorporated by reference. The control node can take different forms depending on the type of service or the type of network to which it is connected.

Description of the Invention (3) ~~~~~ (MSC), which is often combined with the visiting location register (VLR). For connection to a General Packet Radio Service (GPRS), such as the Internet (for example), the control node may be a Gateway GPRS Support Node (GGSN). In the 〇1 ^ 3 system, there can also be one or more serving GPRS support nodes (S G S N). The SGSN is a node serving the mobile station. For example, the node performs the mobile management context on the GPRS attachment and performs the establishment of the PDP context on the pDp context start. Importantly, the current service uses the SGSN node of the mobile station's GPRS. The address must be known to the gSN so that the data packet is routed between the data packet network and the mobile station. The owner of the mobile station usually enters into a contract or a signed consent with a service provider (for example, a company that operates a telecommunications network to enable the mobile station to engage in telecommunications connections over the network). The mobile station was listed as one of the most accessible categories on the network, and yesterday was a partial consent. The signature data of the appointment consent is stored in a maintained record, such as the local location register (HLR) of the mobile station. A roaming mobile user moves freely on the network, and the network knows the location of the mobile station. This approach makes it possible for the mobile user to receive calls no matter where they are located. In order to keep the user up to date on the network, the mobile station must notify the system whenever it changes its location. This method is called location update. An updated version is the so-called " attach " (attach). The IMSI attachment is used by the mobile station to notify the system that it will enter active mode again if it enters the same location area as in the non-active state.

Invention Description (4) Paragraph 2 +) (Digital Cellular Telecommunication System Phase 2+), General Packet Radio Service Service Description Version 2.0.0 TS GSM 03.60 (General Packet Radio Service (GPRS) Service Description V2.0.0) The entire contents of the GSM Attachment Procedure 'are hereby expressly incorporated by reference in their entirety, and thus contain paragraph 6.5. Generally, in the GSM attachment procedure, the mobile station having GPRS capability sends an attachment request message to the SG N node. The SG N node performs identification, authentication, and IMEI operations. After that, the SGSN node sends a location update message to the mobile station's local location register (HLR). The HLR performs a cancel position procedure and then performs a user profile insertion procedure associated with the mobile station. When doing so, the H L R sends the user-specific information of the mobile station to the SGSN. After receiving the user data sent by the HLR, the SGSN will return an update confirmation message as confirmation. Thereby, the location update procedure is executed, and then the SGSN sends an attachment acceptance message to the mobile station. Ministry of Economic Affairs, Central Bureau of Standards, Consumer Cooperatives, Printed Gateway, G PRS Support Node, GG SN, must know the address of the SGS Ν node of the mobile station using GP RS for the current service. To mobile stations. In the previous art, 'the final GPRS support node will only be notified of the last serving GP RS when (1) when the packet data protocol context start is executed, or (2) when there is an inter-SGSN (inter-SGSN) routing update; The address of the supporting node. The prior art of notifying the address of the final serving GPRS support node (SGSN) to the gateway GPRS support node (GGSN) does not cater to all uses of the mobile station. In this regard, the PDP context initiation procedure will only be performed by the mobile station in order to be able to send / receive block exchange information. Therefore, this paper size applies the Chinese National Standard (CNS) A4 specification (210X297). 415152 A7 _____ Β7 V. Description of the invention (5) The previous technology does not provide the ability for end users to receive data packets until the PDP context starts the procedure This ability is only implemented when the fact that the GGSN has no SGSN address is generated. The idea of providing a different interface between the gateway GPRS support node (GGSN) and the HLR has been proposed before. The HR contains the reservation information of the mobile station ′ to provide the address of the final service GPRS support node (SGSN) to the GGSN. However, this view requires a new interface when establishing and producing new protocols. Therefore, what is needed by the present invention and its purpose is to 'notify the gateway GPRS support node's final service address of the GPRS support node in a more general environment. skill. Summary of the Invention The address of the nearest serving GPRS support node (SGSN) is provided to the gateway GPRS support node by a special update SG N address request message sent from SG N to G GN. For a user, the reservation allows the address of the most recent SGSN of the Qualified Packet Data Protocol (PDP) context to be sent in the Update SGSN Address Request message.

It must be understood that no equivalent mapping is required. It is only for convenience of explanation. Furthermore, more SGSNs can or may be connected to G GSN 2 0, so the entire network may be complicated. The dashed dashed lines between HLR 26i, HLR 262 and GGSN 20 indicate that possible communication paths can be established between each HLR and GGSN 20. However, ' This communication path will require a new interface to establish and complete. As explained below, the present invention eliminates the need for an interface / protocol involved between the HLR and GGSN 20. The mobile station (MS) 40 can use one or It is a plurality of general packet radio services (GPRS). The operator of the telecommunication network as shown in Fig. 1 has an appointment agreement for the mobile station (MS) 40. The appointment agreement is related to and manages the mobile station ( MS) 40 operating various protocols and conditions. Information including reservation data reflecting, for example, these specific reservation protocols and conditions of the mobile station (MS) 40 is stored in the HLR 26ι. In the above view, the telecommunications network Each mobile station has a location register, which is regarded as a " local " register. In the illustrated example, 菘 HLR 2 6 1 is the mobile station (M s) 4 〇 " Site, register Therefore, the HLR 261 has the so-called " local " records of each mobile station, including the record of mobile station (MS) 40. 11 paper-scale paper caps. · 醉 · I-----I---- 1 I —I— f ...-^^ 1Ί (Please read the notes on the back before filling out this page) Printed by A7 B7, the Consumer Work Cooperative of Shenyang Bureau of Standards, Ministry of Economic Affairs 5. Description of the Invention (9) Previous Skill Storage An example of the format of the GPRS reservation data record in HLR 261 is shown in Table 1. The first bit of the HLR 2 6 1 record confirms the particular mobile station to which the record belongs. The first record contains the international mobile subscriber identity (IM SI) of the mobile station. For each mobile station, the identifier is Only-of. For mobile station (MS) 40, which is suitable for the type of packet data agreement (for example, if it is related to its appointment agreement), the record in HLR 261 also contains " context ". Basically, the " context " is the information a user needs to use a specific packet data agreement (P D P) such as X. 2 5. An example of the context of the packet data agreement ("p oop ,,) is shown in the last six field groups in Table 1. If the mobile station (MS) 40 is suitable for using two packet data agreements, the record must contain 2 If three packet data protocols are suitable, the record needs to include three such paste groups; and so on. Normally, 'the activation of the PDP context enables the SGSN to establish the user's PDP context. (Refer to Table 3) 'Also enables users to send and receive packetized data. A static p DP' 'address is combined with the user's action ID and placed in the PDP context reservation.

Description of the invention (but the format of Table 1 is only provided as a specific implementation example. At this time As shown in FIG. 1, the GGSN 20 knows how to route a packetized radio connection request from the outside to the mobile station (MS) 4 0. In particular, as shown in the example shown in FIG. 1 'if to the mobile station (MS) 40 When a data packet connection is requested, GGSN 20 will query HLR 26ι. GGSN 20 will record the second stop from, for example, HLR 2 6 1 (assuming the format in Table 1) that mobile station (M s) 4 〇 SGSN 24 1 and found the SGSN address of the mobile station (MS) 40. When the mobile station (MS) 40 moves to another location that is not served by SGSN 24 !, it will complicate. An example is the mobile station (MS) 40 moving along path 50 in FIG. The location shown in Figure 2. In the location shown in Figure 2, the mobile station (MS) 40 is in radio contact with the base station system (BSS) 302 instead of radio with the base station system (BSS) 30i. The contact is therefore under the jurisdiction of SGSN 242 and not under the jurisdiction of SGSN 241. However, at this point in this view, the GGSN 20 would easily forget the mobile station (MS) for data packet services 4 0 The fact that this is being served by SGSN 242 and not being served by SGSN 241. Under certain conditions, the GGSN 20 will eventually be notified. In the case in FIG. 2, the mobile station (MS) 40 is now served by the SGSN 242 rather than the SGSN 241. One such situation is when the mobile station (MS) 40 seeks to activate one of the packet data services by initiating the transmission of the packetized data from the mobile station (MS) 40. The situation is that signals are sent with mutual SGSN routing updates. Until one of these conditions occurred, the mobile station (MS) 40 was still unable to receive the data cover-13-This paper size applies to Chinese national standards (CNS > Α4 size (210 × 297 mm)) Please read first Note on the back, please fill out this page again} Stupid-< 1Τ Printed by the Consumer Standards Cooperative of the Central Standards Bureau of the Ministry of Economic Affairs 415152 A7 B7 _ V. Description of the invention (11) Package, because GGSN 20 does not have the current SGSN address β This invention provides GGSN 20's current SGSN address and therefore allows the mobile station (MS) 40 to receive data packets even before any PDP context initiation is performed. In particular, the present invention allows the mobile station (MS) 40 " attach " To the SGSN. The present invention enhances the mobility management of the MS by transmitting the SGSN address of the current serving mobile station (MS) 40 to the HLR through the interface Gn between the GGSN and the SGSN. Therefore, the present invention commands the The SGSN sends its address to the GGSN 20 and provides the current SGSN address of the GGSN 20. The new SGS N address is provided to the GGSN 20 with a so-called new message update s GS N address request message. For the user, Its appointment The final SGSN node address may be transmitted in the update SGSN address request message of a qualified packet data protocol (PDP) context. A qualified PDP context (1) with a static PDP address (2) is not started. The update s GSN The address request message can be sent from the SGSN to the GGSN in the GPRS attachment outline or the mutual SGSN routing area update outline, as explained below. Before the details of the attachment procedure are discussed in the GPRS attachment outline, the action of the GPRS attachment will be explained first. A station can use its IMSI to attach to the SGSN. The present invention is particularly related to GPRS-capable mobile stations; for example, as described by the Global System for Mobile Communications (ie, GSM), non-GPRS attached mobile stations form IM SI attachments. A Class A mobile station with IMSI attachment in a circuit-switched connection (CS) does not indicate that it is an IMSI attachment when it performs a GPRS attachment.

Known by SGSN 242. The attachment request message of step 3-1 contains ′, for example, information parameters about the mobile station (MS) 40: I μ SI, MS category, category flag, CCS, attachment category, and d R X parameter. This attachment request message is sent to the base station system 3 02 to S G S N 2 4 2. The information parameters included in the Attach Request message in steps 3-1 are briefly discussed at this point. The "MS Type" parameter indicates whether the mobile station is a type A, B, or C mobile station. The class tag " parameter includes the G P R S multicast capability of the mobile station and the supported GPRS encryption algorithm in addition to the existing class tag parameters. The " attach type " parameter indicates what type of attachment will be performed ', that is, only a GPRS attachment' is only an IMSI attachment or a combined G P R / 1M S I attachment. When the MS is already attached to the IM SI, the combined GPRS / IMSI attachment can also be used in the case of GPRS attachment. The "DRX" (discontinuous reception) parameter indicates whether the mobile station is discontinuous reception. If the mobile station uses discontinuous reception, the DRX parameter also indicates when the mobile station is in non-sleep mode and can therefore receive paging requests and channel assignments. If it does not use its IMSI in the attachment request message, the mobile station (MS) 4 0 identifies itself as having a TLLI (the outline illustrated in FIG. 2 'where the current SGSN has changed at the time of separation). In steps 3-1a, the new SGSN (for example, SGSN 2 4 2) Send an identification request to the old SGSN (for example, SGSN 24ι) to request the IMSI of the mobile station (MS) 40.

The description of the invention (16) (roughly described in steps 3-4 in Figure 3) is performed. In order to describe these steps in more detail, Fig. 3A explains in step 3-4a that the HLR 26 丨 sends the cancel position message to the old SG N 2 41. The cancellation location message contains the IMSI of the mobile station (MS) 40. When the cancellation location message is received, the old SGSN 24 removes the mobility management (MM) and pDp context, and confirms the cancellation with a cancellation location confirmation message in step 3-4b. The cancellation location confirmation message contains the IMSI of the mobile station (MS) 40. After the cancel position operation is performed, an insert user data (ISD) operation is performed. In this regard, at step ^ HLR 26, send the insert user profile message to the new S G S N 2 4 2. In this insert user profile operation, the HLR 26 丨 sends all GPRS related information of each PDP type of the mobile station (MS) 40. The insert user profile message of step 3-4c therefore contains the IMSI and GPRS reservation data of the mobile station (MS) 40 (refer to table! And table 2). The insert user information of PDP type can be understood by referring to Table 1. In step 3-, the new SGSN 242 confirms with the insert user profile confirmation message including the mobile station (ms) 40 IMSI.

After the description of the invention (17) is completed, confirm the update location information of steps 3-3 by sending an update location confirmation message to the new SGSN 242. As a result of receiving the inserted user profile, the SGSN 242 checks whether any PDP status is (1) not active, and (2) in this state, the HLR allows S G S N to notify G G S N of the new S G S N address. If any p DP status meets these 2 criteria, the new message-Update S g SN address request message-will be sent from SGSN 242 to GGSN 20 in steps 3-6 »In the update SGSN address request message 'SGSN 242 provides a new SGSN (ie, SGSN 242) address to all pdp contexts with static PDP addresses that are not enabled. The update SS address request message in Buxiang 3-6 includes the following: information element, IMSI, SGSN address, and reason for the update. The update reason information element of the SGSN address update request message has one of two values. The first value indicates the update initiated by the GPRS attach procedure (refer to the conditions described in Figures 3 and 3A). The second value indicates the update initiated by the GP's mutual routing area update procedure (refer to the conditions described in Figs. 4 and 4A). This information can be used by the GGSN for statistical purposes or by the GGSN based on how the ggsN obtains the SGSN address. As mentioned earlier, 'In the present invention, an additional field known as' S G S N address update permission' (refer to Table 2) for G p s reservation data is introduced in HLR 26 and SGSN 242.

The location update procedure is described in more detail in Figure 3A with reference to steps 3-8a to 3-8g. If the mobile station (MS) 40's attachment request in step 3-1 is IMSI Attach, then the new SGSN 242 forwards the IMLR to which the IMSI is attached to the new MSC 282. The VLR 2 92 address has evolved from RA information. In this regard, if the mobile station (MS) 40 is already attached to IMSI and GPRS attachment is in progress , Then the combination is generated by sending a location update request message to VLR 292 (at steps 3-8). This way the mobile station (MS) 40 is marked as a GPRS attachment in VLR 292. This is sent to VLR The location update request message of 292 contains the new LAI, IM SI, SGSN address, GPRS attachment status, and MS type. The GPRS attachment status included in the location update request message indicates that the mobile station (MS) 40 is attached to GPRS, so VLR 292 saves SGSN address and MS class.

Invention Explanation (21) Step 4-1 of FIG. 4 shows that the mobile station (MS) 40 sends a routing area update request message to the SGSN 242. In step 4-2, the SGSN 242 executes the SGSN context procedure and transmits the packet. The SGSN context procedure and packet transfer are described in more detail in Figure 4A. Step 4-3 shows the effectiveness of traditional security functions. Step 4-4 is about operations of various PDP contexts; step 4-5 is about updating position, canceling position, and ISD operation. Steps 4-4 and 4-5 will be described in more detail in order with FIG. 4A. In step 4-6, the SGSN 242 sends an update SGSN address request message to the GGSN 20. Before sending the Update SGSN Address Request message to GGSN 20, SGSN 242 checks to determine if there is any PDP status (1) inactive; (2) the HLR allows the new SGSN to notify GGSN of the new SGSN address. If these checks are positive, in step 4-6, the update SGSN address request message is sent from SGSN 2 4 2 to GGSN 2 0, and a new message provides a PDP context with a static address and a non-active state. SG SN address. Printed by the Consumers Cooperative of the Soap Bureau of the Ministry of Economic Affairs (please read the note on the back before filling this page) In response to the message from step 4-6, at step 4-7, GGSN 20 sends a response message to update the SGSN address to SGSN 242. Inform whether the update of the new SGSN address has been successful. This step (in steps 4-8) is followed by a location update operation. Then, in step 4-9, the routing area update accept message is sent from the SGSN 242 to the mobile station (MS) 40. Finally, in step 4-10, the routing area update completion message is sent by the mobile station (MS) 40 to the SGSN 242 6. Further details of the operations performed in FIG. 4 are now described with reference to FIG. 4A. Similar to FIG. 4, FIG. 4A shows that the mobile station (MS) 40 sends a routing area update request message to a new S G S N (for example, s G S N 2 4 2) at step 4.1. The -24- This paper size applies the Chinese National Standard (CNS) M specification (2 丨 〇 < 2 mm) 415152 A7 B7 V. Description of the invention (22) The routing area update request message contains the parameter TLLI, the new ci ' Old RAI, new RAI, and CS connections. This parameter CI is added to the base station system (BSS) to reduce the load on the radio interface. This parameter cs connection indicates whether the mobile station (MS) 40 has an ongoing cs connection. If there is a CS connection, the SGSN 242 does not send a location update request message to the MSC / VLR (for example, MSC 282). Step 4-2 in FIG. 4 generally involves the SGSN context procedure and the packet transfer procedure. Further details of step 4-2 are shown in Figure 4A. In step 4-2a, the new SGSN (ie, SGSN 242) sends an SGSN context request message to the old SGSN (ie, SGSN 24) to obtain the MM and PDP context of the MM and mobile station (MS) 40. The SGSN context request message Contains the following parameters: 'Old RAI, TLLI, and new SGSN address. In step 4-2b, the old SGSN (ie, SGSN 24 丨) responds with the SGSN context response message. • The SGSN context response message contains the MM context. , PDP context, and LLC confirmation.

Description of Invention (23) The following will be eliminated. As shown in step 4A As shown in Figure 4-2c, the old SGSN 24ι starts to temporarily store the N-PDUs to the new SGSN 242. The remaining N-PDUs received by the GGSN 20 are also passed to the new SGSN before the timer described in step 4-2b ends. The SGSN 242 β has been sent to the N-PDU of the mobile station (MS) 40 and the N-PDU that has not been confirmed by the mobile station (MS) 40 to pass through the multiple LLC boxes of the last segment of the N-PDU.

T Printed by the Consumer Standards Cooperative of the Central Standards Bureau of the Ministry of Economic Affairs A7 B7 V. Description of the Invention (24) In steps 4-5a in Figure 4A, the new SGSN 242 notifies the HLR 26i of the change of the SGSN by sending the updated location information to the HLR 26i. The update location message contains the following parameters: S G S N address and IM S I. Then, in step 4-5b, the HLR 26 cancels the MM context in the old SGSN (i.e., SGSN 2 4) by sending a cancel location message to the old SGSN. The cancel position message contains I M S I of the mobile station (MS) 40. If the timer described in step 4-2 is not counting, the old SGSN will move away from the MM and PDP contexts and confirm by canceling the position confirmation message at step 4-5c. The cancel position confirmation message contains the IMSI of the mobile station (MS) 40. At steps 4-5d, the HLR 26 sends the inserted user profile to the new SGSN 242. The inserted user profile contains the IMSI and GPRS subscription data of the mobile station (MS) 40. In step 4-5e, the SGSN 242 confirms by inserting a user profile confirmation message. The insert user information confirmation message includes the IMSI of the mobile station (MS) 40. The HLR26i confirms the reception of the update location message by sending an update location confirmation message to SGSN 2 4 2 in step 4-6. The update location confirmation message includes I M S I of the mobile station (MS) 40. Steps 4-6 use the new update SGSN address request message of the present invention.

Explanation of the invention () The reason for updating the information The information element in this second outline has a value indicating the procedure for updating the G p RS mutual SGSN routing area (this case will be referred to FIG. 4 and FIG. 4 A Preface is described). In response to the update SGSN 242 address request message in step 4-6, in step 4-7, the GGSN 20 sends back an update SGSN address response message to SGSN 242 to suggest whether the update of the SGSN 242 address update has been successful. The information element in the update SGSN address response message contains the information element and reason. Fig. 4 has steps 4-8 series about the location update operation, which will be further described at this time with reference to Fig. 4A. If the mobile station (MS) 40 is attached to the IM SI and is not a CS connection, the combination between SGS Ν 2 4 2 and VLR 2 9 2 must be updated. The address of VLR 292 evolved from RA information. Step 4-8a: The SGSN 242 sends a location update request message to the VLR 292. The location update request message in step 4-8a contains the following parameters: IM SI, SGS Ν address and GPRS attachment status β. In response, VLR 292 stores the SGSN address (step 4-8b) and includes the mobile station (MS ) 40 IMSI location update acceptance message for confirmation. Printed by the Consumer Standards Cooperative of the Central Bureau of Standards of the Ministry of Economic Affairs SGSN 242 verifies the existence of mobile station 40 in the new RA. If the mobile station (MS) 40 is not allowed to attach to the RA due to regional, national, and international restrictions, or the check fails, then SGSN 242 will reject the path update for an appropriate reason. If all checks are successful, then S G S N 242 will establish the MM of the mobile station (MS) 40 and the PDP context. A logical link between the new S G S N 2 4 2 and the mobile station (MS) 4 0 is established. The new S G SN 2 4 2 responds to the mobile station (MS) 40 with the routing area acceptance message in steps 4-9. The routing area accepts the message containing the following parameters: tlli, -28- ____—— (Please read the notes on the back and fill in this 筲) This paper size applies the Chinese National Standard (CNS) 厶 4 rules _ grid (210X297 public t } 415152 A7 B7 V. Description of the invention (26) PLMN-supported MT capabilities, LLC confirmation, and reasons. If PLMN-supported MT capabilities indicate that only GPRS MS Class C operation mode is supported, that is, the G s interface is not installed; Then category a or b mobile station will (1) perform an exact I μ SI separation via a non-GPRS control channel (if the MS is already attached for IMSI); or (2) non-GPRS accessing circuit switched (CS) operation Control channel (the method of line deblocking operation performed in parallel with GPRS operation is the subject of MS production, which is beyond the scope of the present invention); or (3) avoid all circuit deblocking signals (in this case, the MS is a hidden IMSI Separation).

If the PLMN-supported MT capability parameter indicates that GPRS MS Class A and Class B operation modes are also supported, and the mobile station used for communication with SG SN supports only Class C operation mode, then I μ SI attachment and location update are required The Type A and Type B mobile stations must perform via this SGSN. In addition, if a Type A or Type B mobile station has been attached for IM S I, it immediately performs a location update via so SN to allow the VLR to store the SGSN address. The L LC confirmation parameter of the routing area update acceptance message includes the acknowledgement of each LLC connection used by the mobile station '. Therefore, before starting the update procedure, it is determined that all mobile-oriented N-P D U are successfully transmitted. Printed by the Consumers' Cooperative of the Central Bureau of Standards of the Ministry of Economic Affairs (please read the notes on the back before filling out this page) In step 4-10, the mobile station (MS) 40 confirms the new T L LI with a routing area update completion message. The routing area update completion message contains the following parameters: T L L I and L L · C. The L L C parameter includes the acknowledgement of each L L C connection used by the mobile station. Therefore, before starting the update procedure, it is determined that all mobile-oriented N-PDUs are successfully transmitted. If the 1Lc confirmation parameter determines the reception of the N-PDUs forwarded by the old SGSN, then these N_pDU must be -29- this paper size is appropriate national standard (CNS) A4 specification (210X297 mm) A7 B7 V. Invention Note (27) shall be discarded by the new SG SN. L L C and S ND C P in M S must be reset in situ. If the route update operation is rejected, the new SGSN does not establish the MM context due to the limitation of the routing area. This rejection operation is returned to the mobile station with an appropriate cause of error. The mobile station does not retry routing updates to the RA. When the mobile station is turned on, the value of R R is removed. If the base station system (BSS) node 3 0 1 does not answer, the new SG N 242 does not establish the MM context ^ Instead, the rejection operation is returned to the MS mobile station with an appropriate error cause. The mobile station may attempt to reroute to the same RA. Alternatively, the S SN may retry the operation before rejecting the routing update. If the number of failed route update sequence exceeds the maximum number allowed, or when the route update acceptance cause parameter is indicated as rejected, the mobile station enters the IDLE interleaved state.

Therefore, two new G T P messages-the "Update S G S N Address Request" message, and the "Update S G S N Address Response" message-also play an important role in the second outline. In fact, the update SGSN address request message is sent by the new node SGSN 242 to the GGSN node as part of the GPRS attachment procedure and the update procedure of the mutual SGSN routing area.
