Problems solved by technology

[0036] 1. Since the SGSN resends the Identity Request message to the MS multiple times through the BSC / PCU when there is no MS subscription information in the SGSN, the signaling traffic burden of the SGSN and the BSC / PCU is heavy at the initial stage of handover. Affect the performance of GPRS system;
[0037] 2. MS still has to go through many failed Intra-SGSN RAU processes before normally processing the messages sent by SGSN, which cannot fundamentally solve the problem of low success rate of Intra-SGSN RAU

Embodiment 1

[0081] Embodiment 1: Introduce the LLC RESET process into the simple Intra-SGSN RAU process after the cutover of the existing BSC / PCU.

[0082] Such as Figure 6 As shown, this embodiment is in Figure 4 Added LLC RESET process on top of . At this time, the Intra-SGSN RAU process after BSC / PCU cutover includes the following steps:

[0083] Description and processing methods of steps 601-605 and Figure 4 The description and processing methods of steps 401 to 405 in the shown method are completely the same.

[0084] Step 606. The SGSN sends an LLGMM-RESET-REQ message to the MS to negotiate parameters with the MS.

[0085] In this step, the SGSN prompts the MS to set V(U) and V(UR) to the initial value 0 by sending the LLGMM-RESET-REQ message.

[0086] Steps 607-610. The SGSN sends a RAU Reject message to the MS, and adds 1 to the number of Intra-SGSNRAU failures; the MS starts the attach process after sending the LLGMM-RESET-CNF message to the SGSN.

[0087] In this embod...

Embodiment 2

[0091] Embodiment 2: Introduce the LLC RESET process in the improved Intra-SGSN RAU process after the cutover of the existing BSC / PCU.

[0092] Such as Figure 7 As shown, this embodiment is in Figure 5 Added LLC RESET process on top of . At this time, the Intra-SGSN RAU process after BSC / PCU cutover includes the following steps:

[0093] Description and processing methods of steps 701-705 and Figure 4 The description and processing methods of steps 401 to 405 in the shown method are completely the same.

[0094] Step 706. The SGSN sends an LLGMM-RESET-REQ message to the MS to negotiate parameters with the MS.

[0095] In this step, the SGSN prompts the MS to set V(U) and V(UR) to the initial value 0 by sending the LLGMM-RESET-REQ message.

[0096] Steps 707-709. The SGSN sends an Identity Request message to the MS, and then the MS sends an LLGMM-RESET-CNF message and an Identity Response message to the SGSN in turn, and returns to step 703.

[0097] Here, the SGSN fir...

Embodiment 3

[0099] Embodiment 3: Introduce the LLC RESET process after combining the two existing Intra-SGSN RAU processes after the cutover of the BSC / PCU.

[0100] In this embodiment, an identity recognition switch is added to the SGSN, so that the SGSN can determine the way of subsequent interaction with the MS by judging the state of the identity recognition switch.

[0101] Such as Figure 8 As shown, the method for improving the Intra-SGSN RAU success rate after BSC / PCU cutover in this embodiment includes the following steps:

[0102] Description and processing method of steps 801-805 and Figure 4 The description and processing methods of steps 401 to 405 in the shown method are completely the same.

[0103] Step 806. The SGSN sends an LLGMM-RESET-REQ message to the MS to negotiate parameters with the MS.

[0104] In this step, the SGSN prompts the MS to set V(U) and V(UR) to the initial value 0 by sending the LLGMM-RESET-REQ message.

[0105] Step 807. The SGSN judges whether ...

Abstract

The method includes following steps: a) the mobile station sends request for renewing routing area to the SGSN; the SGSN decides if the routing area before renewing belongs to SGSN; if yes, enters into step b; otherwise, enters into the process of renewing routing area between SGSN, and ends the renewing process for current routing area; b) after the SGSN adds 1 to the times of renewing routing area in SGSN, and decides if there is the subscription information of mobile station in SGSN; if yes, enters into step c; otherwise, SGSN informs the mobile station to initialize its own state variable; and then makes process of renewing routing area in SGSN, and ends the renewing process in local routing area; c) adds 1 to the times of successfully renewing routing area in SGSN, and the mobile station informs the completion of renewing SGSN routing area.

Description

technical field [0001] The invention relates to a GPRS routing area update technology, in particular to a SGSN routing area update method after a base station controller / packet control unit cutover. Background technique [0002] General Packet Radio Service (GPRS) is a communication system upgraded on the basis of Global System for Mobile Communications (GSM). It uses packet switching and uses statistical multiplexing and dynamic multiplexing technologies to enable each user in the GPRS network to Multiple wireless channels are selected, and one wireless channel can also be shared by multiple users. [0003] exist figure 1 In the shown GPRS network, the serving GPRS support node (SGSN) is the main functional node wherein, it links to each other with the gateway GPRS support node (GGSN) through the Gn interface, and the home location register (HLR) / authentication center ( AUC), connected with the short message center (SMC) through the Gd interface, connected with the servic...
