Embodiment 1

[0150] In the LTE system, if data is to be sent to a UE in an idle state (RRC state is RRC-IDLE), the MME needs to send a paging message to all eNodeBs in the tracking area (TA, Tracking Area) registered by the UE, and then the eNodeB Send a paging message to notify the UE, such as figure 1 shown. The UE monitors the paging message at the corresponding position according to the calculation formula of the PO. After receiving the paging message, the UE will initiate an RRC connection request to receive downlink data. After sending a paging message, the MME judges whether the paging is successfully received by the UE according to whether the UE performs corresponding actions in the next step. If it is not successfully received by the UE, it will continue paging in the next paging frame interval. Call the terminal.

[0151] In the NB-IOT system, since PSS occupies at least one subframe, it is likely to occupy two subframes; SSS occupies at least one subframe, and PBCH occupies o...

Embodiment 2

[0215] This embodiment provides a base station that can implement the method on the base station side of Embodiment 1 above, which mainly includes the following units.

[0216] A parameter sending unit, configured to determine a paging frame interval according to the number of subframes that can be used for paging in k radio frames, and send the paging parameters corresponding to the determined paging frame interval to the terminal; where k is A positive integer, preferably 1, 2, 4, 8, 16;

[0217] A paging unit, configured to send a paging message to the terminal in a paging frame according to the paging parameter.

[0218] Optionally, sending a paging message to the terminal in a paging frame by the paging unit according to the paging parameter includes:

[0219] The paging unit determines radio frames (identified by SFN) occupied by all paging frames PF within the radio paging transmission window PTW that can be used to send paging messages through paging parameters, where...

Embodiment 3

[0237] This embodiment provides a terminal capable of implementing the method in Embodiment 1 above, which includes the following units.

[0238] An acquiring unit, configured to acquire the paging parameters issued by the base station; wherein, the paging frame interval included in the paging parameters issued by the base station is determined according to the number of subframes that can be used for paging in k radio frames ; Wherein, k is a positive integer, preferably 1, 2, 4, 8, 16;

[0239] Optionally, the acquired paging parameters include at least the paging frame interval, the position of the initial paging occasion PO in the PF, the DRX cycle, and the initial length of the PTW.

[0240] The monitoring unit is configured to monitor paging messages in the paging frame according to the paging parameters.

[0241] Optionally, the monitoring unit monitoring the paging message in the paging frame according to the paging parameter includes:

[0242] The monitoring unit dete...

Abstract

The invention provides a method for monitoring and sending paging messages and paging a terminal, and a base station and the terminal. The method for monitoring the paging messages includes that the terminal generates a first paging monitoring recognition message; the terminal determines the paging superframe requiring monitoring of the terminal according to the first paging monitoring recognition message and monitoring the paging message on the paging superframe.

Description

technical field [0001] The present invention relates to wireless communication technology, in particular to a method for monitoring, sending paging, paging terminal, base station and terminal. Background technique [0002] The rapid development of mobile Internet, Internet of Things, and other business applications has become the main driving force for the development of the fifth generation mobile communication technology (5G). They urgently require 5G to have an access rate comparable to optical fiber, a connection capability of hundreds of billions of devices, a perfect real-time experience, and wireless broadband access anytime, anywhere. In addition, important indicators such as energy efficiency, spectrum efficiency, and peak rate also need to be considered comprehensively in the design of 5G systems. In 2013, China established the IMT-2020 (5G) promotion group to promote the development of 5G technology. According to the overall international situation, it is expect...
