Embodiment 1

[0164] Embodiment 1. In this embodiment, the terminal performs paging retransmission reception at a specific paging location by default. Taking the specific paging parameter as the default paging parameter as an example, the terminal (UE) has multiple paging subframes in one extended paging cycle. specific:

[0165] After negotiating with the core network, the UE determines to use the extended paging cycle (also called the extended paging DRX cycle) (assuming that the extended paging cycle is 20.48 seconds) for paging reception; in this embodiment, it is assumed that the UE The extended paging position calculated by paging parameters (including extended paging cycle, extended paging density, extended paging times, etc.) is subframe #2 of the first radio frame in each extended paging cycle (hereinafter referred to as for extended paging subframe positions), see Figure 6A shown;

[0166] The UE wakes up before each expansion of the paging subframe position to read the system...

Embodiment 2

[0170] Embodiment 2. In this embodiment, the UE enables / disables the receiving function of paging retransmission according to the instruction of the base station. On the basis of Embodiment 1, this embodiment further provides a power saving enhancement solution.

[0171] In Embodiment 1, the UE needs to wake up twice in each extended paging cycle to receive paging. When there is no paging in the extended paging cycle, it is wasteful for the UE to wake up one more time. Therefore, the base station can indicate whether the UE needs to wake up at the default paging subframe position through system information. If the UE receives the system information of the cell before the extended paging subframe, and the system information indicates that it does not need to wake up at the default paging subframe position, then the UE will only receive paging at the extended paging subframe position ,Such as Figure 7A Shown:

[0172] In addition, the base station may also use a paging messag...

Embodiment 3

[0175] Embodiment 3. In this embodiment, the UE has multiple paging subframes in one extended paging cycle (based on retransmission paging parameters);

[0176] After negotiating with the core network, the UE determines to use the extended paging cycle (for example, 20.48 seconds) for paging reception; in this embodiment, it is assumed that the extended paging position calculated by the UE according to the extended paging parameters is Subframe #2 of the first radio frame in (hereinafter referred to as the extended paging subframe position), as follows Figure 8A shown;

[0177] The UE wakes up before each extended paging subframe position to read the system information of the cell it is currently camping on, and saves the retransmission paging parameters specially used for paging retransmission (for example, the retransmission paging cycle of the current cell is 2.56 seconds, the number of retransmission paging is 2 times), the retransmission paging parameters are different ...

Abstract

The invention discloses a paging method, a device and a system so as to solve the long time delay and paging reception low reliability problems when a terminal in the prior art uses an expanded DRX period to monitor; the method comprises the following steps: the terminal carries out paging reception in an expansion paging position of each expansion paging period; the terminal carries out a paging retransmission reception in at least one specific paging position besides the expansion paging position in at least one expansion paging period. Because the terminal carries out at least two paging receptions in at least one expansion paging period, so power saving effect of the terminal can be improved, and paging reception time delay and reliability can be ensured, thus improving user experience and system performance.

Description

technical field [0001] The present invention relates to the technical field of wireless communication, in particular to a paging method, device and system. Background technique [0002] For the wireless network side, in the Long Term Evolution (LTE) system, the terminal has two states, namely RRC_connected (connected) state and RRC-idle (idle) state; Universal Mobile Telecommunication System (Universal Mobile Telecommunication System, In UMTS), the terminal has five states, namely cell-dch, cell_fach, cell_pch / ura_pch and idle (idle) state, among which cell-dch, cell_fach, cell_pch / ura_pch all belong to the RRC_connected (connected) state. The terminal can only send uplink data when it enters the RRC_connected state. Once the terminal finishes sending uplink data, the network side monitors that the terminal has no data transmission for a long time, and releases the RRC connection of the terminal through the RRC connection release (Radio Resource Control, RRC) message, so th...
