Description

Method for sending paging message, method and equipment for receiving paging message

Technical Field

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

Background

In Long Term Evolution (Long Term Evolution, LTE)/New Radio (NR), when downlink data arrives or a system message is updated, paging is initiated to a terminal (e.g., User Equipment (UE)) in an idle (idle) or inactive (inactive) state. A Mobility Management Entity (MME)/Access and Mobility Management Function (AMF) sends a paging message to a network side device (e.g., a base station (eNB/gNB)) included in the MME according to a Tracking Area (TA) or an Access network Notification Area (RNA) registered by the terminal, and the base station continues broadcasting the paging message, thereby informing the UE to initiate Radio Resource Control (RRC) connection establishment or receive a new paging message.

For power saving, UE paging Reception follows the principle of Discontinuous Reception (DRX), each cell broadcasts a cell default DRX paging cycle (cell specific DRX cycle) to all UEs in the cell in system information, and each UE may also set a UE specific DRX cycle according to its own power and paging system, and sends the UE specific DRX to the MME/AMF through a Non-Access-Stratum (NAS) message Attach Request (Attach Request) or a Tracking Area Update (TAU) Request. The MME/AMF passes the specific DRX information of the paged UE to the base station. The UE wakes up according to the DRX period (namely the smaller value of the cell specific DRX period and the UE specific DRX period) appointed between the UE and the base station to receive the paging message.

For a common UE, a current cell broadcasts a unified cell specific default DRX cycle (default DRX cycle), and is not distinguished for UEs with different power saving requirements, for example, a UE with a higher power saving requirement has a shorter DRX cycle configuration at a cell level, which results in a shorter DRX that is actually used last, and needs to wake up frequently to detect a Physical Downlink Control Channel (PDCCH). On the other hand, the grouping of the paging messages is also performed according to the terminal identity (UE-ID) and is not related to the power saving requirement of the UE, so that the UEs with different power saving requirements may be awakened at the same time.

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

Mode 2: the power saving information indicates whether the terminal is in a power saving state;

for example, when the network side device is a base station, the base station may acquire that the terminal is in the power saving state through the MME or the AMF, and for example, the base station may acquire that the terminal is in the power saving state through a paging (paging) message (e.g., an S1AP paging message).

Illustratively, the value of the default discontinuous reception period of the basic cell level may be rf64, although it is not particularly limited.

For example, the network side device broadcasts a basic value, such as rf64, and then broadcasts a set of coefficients {1/2, 1, 2, 4}, which indicate that default DRX cycles used by UEs with different power saving levels are rf32, rf64, rf128(128 radio frames), and rf256(256 radio frames), respectively.
