Description

Paging, receiving paging, paging control method and device

This application claims the priority of the Chinese patent application filed on August 12, 2016, the Chinese Patent Office, the application number is 201610664779.6, and the application name is “Paging, Receiving Paging, Paging Control Method and Device”. The citations are incorporated herein by reference.

Technical field

The present application relates to the field of communications technologies, and in particular, to a paging, receiving paging, paging control method and apparatus.

Background technique

In a Long Term Evolution (LTE) system, a user equipment (User Equipment, UE) has two states, a radio resource control connection (RRC-connected) state and an idle (RRC-idle) state. In order to perform mobility management for the UE and data transmission and reception of the UE, the network uses a large amount of signaling. In order to save the signaling overhead of the air interface, a new RRC state, called Light Connected (LC) state, is introduced in the LTE Release 14 (Release 14, R4) phase. When the UE is in the LC state, the connection between the Evolved Node B (eNB) of the UE and the packet core network (S1 connection) is still maintained, so the Mobility Management Entity (MME) considers the UE non- The access layer (Non-Access Stratum, NAS) state is connected. A schematic diagram of state transition of the UE is shown in FIG. 1.

When the UE is in the LC state, data transmission and reception cannot be performed, but paging can be received on the air interface. When there is a message transfer (MT) service, the Serving Gate Way (S-GW) transmits data to the eNB (anchor eNB) that maintains the S1 connection of the UE through the user plane interface (S1-U interface), anchor The eNB initiates paging on the air interface, and the UE receives the MT service after responding.

From the wireless network side, in the LTE system, the UE can only send uplink data when it enters the RRC-connected state. After the UE sends the data to complete, the network monitoring UE releases the RRC connection of the UE through the RRC-connection release message after the data transmission is not performed for a long time, so that the UE enters the RRC-idle state.

In the existing extended discontinuous reception (eDRX) paging mechanism, the main work of the UE in the RRC-idle state is to listen to the paging on the network side, and use the eDRX mode to monitor the paging in order to save power. As shown in FIG. 2, the UE receives a page using a discontinuous reception (DRX) method in a paging time window (PTW) in one superframe (10240 ms) in each eDRX paging cycle. Other times are non-receiving.

For the paging process, as shown in FIG. 3, the core network (CN) entity initiates paging, and the paging disappears. The information is first sent to the eNB. The paging message carries the eDRX configuration of the UE, including the eDRX cycle and the PTW. For LTE systems, the eNB will use the eDRX configuration related parameters to send paging messages. The paging message sent by the eNB carries the marked UE identifier. After receiving the paging message, the UE finds that it contains its own paging identifier, and then responds to the paging, and enters the RRC-connected state by initiating the connection establishment process.

In the prior art, the eDRX paging mechanism is designed for the UE in the RRC-idle state. When the UE is in the LC state, the eNB cannot obtain the eDRX parameter of the UE, and cannot perform eDRX searching for the UE in the LC state. call.
