Description

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

Technical Field

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

Background

In order to save power consumption of a terminal (User Equipment or terminal), a DRX (Discontinuous Reception) period of an idle terminal is extended in LTE (Long Term Evolution). The eDRX period is 256HFN (Hyper Frame Number) maximum, for example 256 × 10240 ms. When the eDRX period is configured, the terminal monitors paging according to the eDRX period as the period, and monitors paging only in a determined paging time window according to the original DRX mode in each eDRX period.

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

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

1) the idle state terminal monitors the paging message and monitors the paging message according to a period T, wherein the period T is the minimum value of a DRX value special for the terminal (the DRX value is the minimum value of the DRX value of the terminal in a connection state, which is obtained by negotiating with a core network, and the core network is configured for the terminal) and a default DRX value broadcasted in system information. If the terminal does not have a dedicated DRX value, T is a default DRX value of system information broadcast.

2) When the terminal in the inactive state enters the inactive state, the radio access network side will notify the terminal to enter the inactive state through related configuration information carried in a Radio Resource Control (RRC) release message, where the related configuration information includes a radio access network paging cycle used for the radio access network side to page the terminal to enter the connected state. The terminal can negotiate with the core network in a connected state, the core network configures a special DRX period for the terminal, and the terminal in an inactive state monitors the paging message according to a period T when monitoring the paging message, wherein T is the minimum value of a DRX value special for the terminal (a paging period of a radio access network configured on the side of the radio access network or the special DRX period configured for the terminal by the core network) and a default DRX value broadcasted in system information.

The NR system supports releasing the terminal to enter an inactive state or an idle state, the terminal entering a connection state from the idle state or the inactive state is controlled by the radio access network side, and there is no clear scheme for how to configure and apply the eDRX parameter in the inactive state.
