Description

Paging message sending method, paging message receiving method and equipment

Technical Field

The embodiment of the invention relates to the technical field of communication, in particular to a paging message sending method, a paging message receiving method and equipment.

Background

In long term evolution (Long Term Evolution, LTE)/New Radio (NR), when there is downlink data arrival or system message update, paging is initiated to a terminal (e.g., user Equipment (UE)) in idle or inactive state. The mobility management entity (Mobility Management Entity, MME)/access and mobility management function (Access and Mobility Management Function, AMF) sends a paging message to a network side device (e.g., a base station (eNB/gNB)) contained in the Tracking Area (TA) or the access network notification Area (Ran Notification Area, RNA) according to the Tracking Area (TA) registered by the terminal, and the base station continues to broadcast the paging message, so as to inform the UE to initiate radio resource control (Radio Resource Control, RRC) connection establishment or receive a new paging message.

In view of power saving, the UE paging reception follows the principle of discontinuous reception (Discontinuous Reception, DRX), each cell broadcasts a cell default DRX paging cycle (cell specific DRX cycle) in system information to all UEs in the cell, and each UE may also set UE-specific DRX (UE specific DRX cycle) according to its own power and paging system, and send UE-specific DRX to MME/AMF through Non-Access-Stratum (NAS) message Attach Request or tracking area update (Tracking Area Update, TAU) Request. The MME/AMF delivers specific DRX information of the paged UE to the base station. The UE wakes up to receive the paging message according to the DRX cycle agreed with the base station (i.e., the smaller values of cell specific DRX cycle and UE specific DRX cycle).

For a common UE, a default DRX cycle (default DRX cycle) of a unified cell specific (cell specific) is broadcasted by a current cell, and is not distinguished for UEs with different power saving requirements, for example, UEs with higher power saving requirements, due to a shorter cell-level DRX cycle, the last actually used DRX is also shorter, and it is required to wake up frequently to detect a physical downlink control channel (Physical Downlink Control Channel, PDCCH). On the other hand, the grouping of paging messages is performed according to terminal identification (UE-ID), and is irrelevant to the power saving requirement of the UE, so that UEs with different power saving requirements may be awakened at the same time.

Optionally, the power saving information indicates one or more of the following combinations: (1) a power saving level of the terminal; (2) whether the terminal is in a power saving state.

Mode 1: the power saving information indicates a power saving level of the terminal;

for example, when the network side device is a base station, the base station may obtain the current power saving level of the terminal through an MME or an AMF, for example, the base station may obtain the current power saving level of the terminal through a paging (paging) message (such as an S1AP paging message).

For another example, the network side device is MME or AMF, and the UE reports its current power saving level to the MME or AMF through an Attach Request (Attach Request) or a tracking area update Request (TAU Request) during the Attach (Attach) or tracking area update (Tracking Area Update, TAU).
