Embodiment 1

[0133] Embodiment 1 (with respect to the improvement of prior art Solution A flow process):

[0134] 1. If a downlink data arrives at UP-GW, and "LTE-active or not" indicates only "not", go to step 2.

[0135] 2. If the UP-GW "last used tunnel" identifier indicates that the UE is in the range of the SGSN at last, then the UP-GW sends the downlink data to the UTRA / 2G SGSN;

[0136] A: When the SGSN is 2G-SGSN:

[0137] (1) If the UE is in the Ready state, the SGSN sends data to the BSS to page the UE;

[0138] (2) If the UE is in the Standby state, the SGSN sends a paging, and immediately returns a copy of the downlink data packet to the UP-GW, and uses "paging in a wider area" to indicate that it is paging in a wider area; once the 2G After the paging is completed, the SGSN returns a message indicating whether the UE is reachable to the UP-GW;

[0139] B: When the SGSN is 3G-SGSN:

[0140] (1) If the Iu connection exists, the SGSN forwards the downlink data to the SRNC. If...

Embodiment 2

[0151] Embodiment 2 (compared to the improvement of the process of the UE being in the PCH state in the Solution B mode of the prior art):

[0152] Referring to Figure 7, the specific signaling process is basically similar to Figure 6, namely:

[0153] Process steps 1-9 are the same as those in Figure 6 and will not be repeated;

[0154] In step 10 of the process, there is no need to page the UE in the SGSN, that is, the UTRA area;

[0155] In step 11 of the process, according to the actual access system of the UE, the system returns a paging response;

[0156] In step 12 of the process, a user plane connection is established according to the actual access system of the UE;

[0157] In step 13 of the process, downlink data is sent to the UE.

[0158] When the method of the present invention is combined with the UE camping on the last used RAT (last used RAT) or preferred RAT (preferred RAT) method in the public coverage area, the paging range can be further reduced.

Abstract

The invention discloses a method to reduce the paging district and paging device, which includes: the user device in URA_PCH / CELL_PCH state enters E-UTRA from UTRA, and the user device records the identifier ID of resided URA / CELL before entering E-UTRA, and keeps the period refresh timer of URA / CELL; before the timer becomes due, the user device returns the UTRA, and compares the recorded URA / CELL ID with the returned URA / CELL ID is same or not; if yes, keeps URA_PCH / CELL_PCH state and does not refresh URA / CELL. When the network pages the user device, if the state of user device is PCH state, it just pages the user device in URA which is in the list of equivalence route section distributed for user device or E_UTRA. Using the invention, it can reduce the area to page the user device in network.

Description

technical field [0001] The invention relates to the communication field, in particular to a method for reducing the paging area and paging user equipment. Background technique [0002] Currently in 3GPP, various manufacturers are actively researching Long Term Evolution (LTE). The purpose of LTE is to provide a network that can reduce delay, increase user data rate, improve system capacity and low-cost coverage, and only use PS domain Services and the bearer network are all carried by IP. [0003] A typical two-layer node evolution network architecture is shown in Figure 1, including: [0004] LTE RAN: It is a wireless access network of an evolved network, in which nodes have evolved base station eNodeB, and may have a control plane server (Control Plane Server, CPS), etc. The specific number of nodes is variable, and it is logically called long-term evolution wireless Access network entity (LTE-RAN Entity). [0005] Mobility Management Entity (MME) / User Plane Entity (Use...
