[0483] Figure 19 It is a flow chart of the UE's P-TAU timing adjustment method / P-TAU timing adjustment support method according to the first embodiment of the present invention. Regarding this flowchart, Figure 18 The descriptions described in are equally applicable, and repeated descriptions are omitted.

[0484] refer to Figure 19 First, the UE may implicitly or explicitly notify the MME / SGSN that the UE can adjust the P-TAU timing through the access request procedure and / or the TAU request procedure (step S1910). To this end, the UE may send an Access Request message and / or a TAU Request message to the MME / SGSN (via the eNB), implicitly / explicitly including P-TAU support information (or P-TAU capability information / adjustable / adjustable / adaptable / adaptable / flexible P-TAU capability information). In this case, in the access request message and / or the TAU request message, DRX (or eDRX) parameters about the DRX (or eDRX) cycle desired (or proposed) by the UE may be addi...

[0502] Figure 20 It is a flow chart of the P-TAU timing adjustment method / P-TAU timing adjustment support method of UE according to the second embodiment of the present invention. Regarding this flowchart, Figure 19 The description described in can be equally applied. Therefore, the following mainly describes the Figure 19 s difference.

[0503] refer to Figure 20 The UE may implicitly or explicitly notify the MME-SGSN that the UE can adjust the P-TAU timing through the access request process and / or the TAU request process (step S2010). In this case, in the access request message and / or the TAU request message, DRX (or eDRX) parameters about the DRX (or eDRX) cycle desired (or proposed) by the UE may be additionally included. This step corresponds to the above step S1910, and repeated descriptions are omitted.

[0504] Next, when the MME / SGSN accepts the UE's access request and / or TAU request, the MME / SGSN may send a request acceptance message to the UE (step S2020)....

Abstract

One aspect of the present invention relates to a method for adjusting periodic tracking area update (P-TAU) timing of a terminal in a wireless communication system. The method may comprise the steps of: sending, to a mobility management entity (MME), P-TAU support information indicating that adjustment of the P-TAU timing is possible through an attach request message or a TAU request message; receiving a request approval message for the attach request message or the TAU request message; and, when the request approval message contains P-TAU timing adjustment condition information, adjusting theP-TAU timing to conform to eDRX application timing on the basis of the P-TAU timing adjustment condition information.

Description

technical field [0001] The present invention relates to a wireless communication system, and more particularly, to a method for adjusting a periodic tracking area update according to a paging message receiving timing and a device supporting the method. Background technique [0002] Mobile communication systems have been developed to provide voice services while ensuring user mobility. However, mobile communication systems expand to the field of data services in addition to voice, and at present, a resource shortage phenomenon is caused due to explosive growth of services and users demand higher speed services, and as a result, further developed mobile communication systems are required. [0003] The requirements of next-generation mobile communication systems mainly need to support adaptation to explosive data traffic, epoch-making increase in transmission rate per user, adaptation to significant increase in the number of connected devices, very low end-to-end delay, and hig...
