Problems solved by technology

[0010] At present, the maximum paging cycle will not exceed the maximum length of the SFN. In practice, especially for MTC terminals that communicate with the network occasionally, even if the maximum DRX cycle is used, it will appear too frequent, which is not conducive to the terminal's power saving.

Embodiment 1

[0056] Embodiment 1: Determination of paging time in LTE system. Such as Figure 5 shown, including the following steps:

[0057] S301. The network side broadcasts and sends system information SIB16, which includes GPS (Global Positioning System, Global Positioning System) time information;

[0058] S302. The network side allocates configuration information referring to GPS time according to the conditions of the accessed terminal, including: specifying the wireless frame at GPS time T1 to initiate paging, the cheap S in the wireless frame, and the paging cycle P, The paging cycle is an integer multiple of the GPS time granularity.

[0059] S303. The network side and the terminal determine the paging time T1+N*P+S; wherein, N=an integer of 0, 1, 2....

Embodiment 2

[0060] Embodiment 2: UMTS system improvement.

[0061] For the UMTS system, since the current network time is only given in the message of MBMS (Multimedia Broadcast Multicast Service, Multimedia Broadcast Multicast Service), and only the LCR TDD mode is used, other modes cannot obtain the system time. Therefore, the LTE method can be similarly used to newly define a system information block (SIB) to carry system time information.

[0062] Similar to Embodiment 1, the terminal calculates the paging location based on configuration information based on system time information.

Embodiment 3

[0063] Embodiment 3: An application scheme for transmission of an internal interface on the network side.

[0064] The network side is actually composed of two layers of equipment, the core network and the access network. The core network manages the paging configuration, and the access network sends paging messages according to the signaling of the core network. When the network needs to page a certain UE, the CN node of the core network sends a paging message to the base station eNB or the network controller RNC, in which in addition to the identity of the UE and the content of the paging message, detailed paging time information is also provided to the receiving terminal. Incoming side. For example, a specific GPS time can be specified each time, and the access network node sends a paging message at the specified GPS time position. In the same way as described in Embodiment 1, the configuration information related to the paging time calculation configured for the terminal ...

Abstract

The embodiment of the invention provides a network side paging method and device and a terminal paging method and device. According to the invention, a paging period is prevented from being limited by a system frame number (SFN), and a terminal is configured to have a relatively long paging period, so that the power consumption of the terminal is reduced. The method comprises the steps of determining the current time to be a transmission time of a paging message, wherein the transmission time of the paging message is determined by negotiation with the terminal by using a standard time in advance; and transmitting the paging message to the terminal.

Description

technical field [0001] The present invention relates to the field of mobile communication, in particular to a network side and terminal paging method and device. Background technique [0002] For the wireless network side, in the LTE (Long Term Evolution, long-term evolution) system, the terminal has two states, namely RRC_connected (connected) state and RRC-idle (idle) state; in UMTS (Universal Mobile Telecommunication System, universal mobile Communication system), the terminal has five states, namely cell-dch, cell_fach, cell_pch / ura_pch and idle (idle) state. Among them, cell-dch, cell_fach, and cell_pch / ura_pch all belong to the RRC_connected (connected) state, and the terminal can only send uplink data after entering the RRC_connected state. Once the terminal sends data, the network monitors the terminal to release the RRC connection of the terminal through the RRC (Radio Resource Control, radio resource control) connection release (connection release) message after a...
