Description

Method, equipment and terminal for configuring discontinuous reception parameters and monitoring paging

Technical Field

The present invention relates to the field of communications technologies, and in particular, to a method, an apparatus, and a terminal for configuring discontinuous reception parameters and monitoring paging.

Background

In order to save power consumption of a terminal (User Equipment, user Equipment or terminal), DRX (Discontinuous Reception ) cycles of an idle state terminal are extended in LTE (Long Term Evolution, long term extension). The eDRX period is maximally 256HFN (Hyper Frame Number, super frame number), e.g., 256 x 10240ms. When the eDRX period is configured, the terminal monitors paging according to the eDRX period as a period, and monitors paging according to the original DRX mode only in a determined paging time window in each eDRX period.

The eDRX cycle length and paging time window length are configured to the terminal by the core network MME (Mobility Management Entity ). When paging a terminal, the core network sends eDRX related configuration information to the RAN (Radio Access Network ) side for paging the terminal at the radio access network side.

In an NR (New Radio) system, the paging cycle determination procedure is as follows:

1) The idle state terminal monitors paging messages according to a period T, wherein the period T is the minimum value of a terminal-specific DRX value (the DRX value is the default DRX value broadcasted in the default DRX value and the default DRX value broadcasted in the system information, and the DRX value is negotiated with the core network when the terminal is in a connected state. If the terminal does not have a dedicated DRX value, T is a default DRX value broadcasted by the system information.

2) When the terminal in the inactive state enters the inactive state, the radio access network side informs the terminal of entering the inactive state through carrying relevant configuration information in an RRC (radio resource control ) release message, wherein the radio access network side comprises a radio access network paging cycle, and is used for paging the terminal in the radio access network side to enter a connection state. The terminal can negotiate with the core network when in a connection state, the core network configures a special DRX period for the terminal, and the non-active terminal monitors the paging message according to a period T when monitoring the paging message, wherein T is the minimum value of the special DRX value of the terminal (the paging period of the wireless access network configured at the wireless access network side or the special DRX period configured for the terminal by the core network) and the default DRX value broadcasted in the system information.

The NR system supports releasing the terminal to enter an inactive state or an idle state, the terminal enters a connection state from the idle state or from the inactive state, which is controlled by the radio access network side, and no clear scheme exists at present how to configure and apply eDRX parameters in the inactive state.

the gNB1 sends a release message to inform the terminal to enter an inactive state. Wherein the release message contains a paging cycle t_ran configured for the terminal by the radio access network configured for the terminal.

Step 2: the terminal determines a superframe HFN for monitoring paging according to T_eDRX, and determines a window position of the monitoring paging according to configuration information L of the PTW length.

The terminal determines the paging cycle t=min (t_ran, t_d, t_amf) according to the default DRX cycle t_d broadcasted in the camping cell and the dedicated DRX cycle t_amf configured by the core network for the terminal. And monitoring paging according to the period T and a default paging monitoring mode in the determined paging time window.

Step 3: the core network has data to arrive, gNB1 triggers the paging of the radio access network side, the gNB1 determines the paging position of the paging hyper frame HFN and the paging window PTW according to the eDRX parameter configured by the core network, namely according to the eDRX period T_eDRX and the PTW length L, and determines the paging position paging terminal in the determined PTW according to the period T_ran and the default paging mode.

Further, the method may further include: step 4: and gNB1 sends a paging message to the adjacent base station to trigger the adjacent paging terminal. The paging message includes configuration information of eDRX, namely eDRX period t_edrx and PTW length L.

step 4: the terminal determines a superframe HFN for monitoring paging according to T_eDRX, and determines a window position of the monitoring paging according to configuration information L of the PTW length. The terminal determines the paging cycle t=min (t_ran, t_d, t_amf) according to the default DRX cycle t_d broadcasted in the camping cell and the dedicated DRX cycle t_amf configured by the core network for the terminal. And monitoring paging according to the period T and a default paging monitoring mode in the determined paging time window.

And determining the HFN position of the paging superframe and the paging window PTW according to the eDRX period T_eDRX and the PTW length L, and paging the terminal at the determined paging position according to a default paging mode in the determined PTW.

Further, step 6: and gNB1 sends a paging message to the adjacent base station to trigger the adjacent paging terminal. The paging message includes eDRX configuration information, i.e., eDRX period t_edrx and PTW length L.
