Problems solved by technology

[0007] One of the objectives of the present invention is to provide a method for sending system control messages, so as to overcome the disadvantage of the prior art that the UE in the active state cannot be notified when the system message changes, so that when the system message changes, all the UEs in the system can be notified in time UE

Embodiment Construction

[0080] The core of the present invention is that after the system control message changes, the network side schedules channel resources, sends the changed system control message to the user equipment UE (idle state or active state), and sends a system control message change indication to notify The UE reads the system control message sent by it, and notifies all UEs in all states of the changed system control message in time. Based on this transmission method on the network side, when the UE selects a new cell, or when the UE (idle state or active state) receives the system information change indication information sent by the network side, it can change the cell according to the system broadcast message or the system information. The indication information acquires the location of the system control message, so that the UE can acquire the changed system control message according to the location information.

Abstract

The invention disclose a method used for a system to control message sending and receiving, when the system control message changes, the network side attemper channel resource sends the changed system control message to the user equipment UE; the network side controls the message changing instruction through the sending system, and informs UE of reading the sent system control message. Based on the sending method, when the user equipment UE chooses a new subdistrict, or when UE receives the system message changing instruction information sent by the network side, the invention gets the position of the system control message through the system broadcasting message or the system message changing instruction information, and then the information on the position is read to get the system control information. The invention also discloses a system control message sending and a receiving device. By using the invention, the idlesse UE and the activated UE can be made to effectively receive the changed system control message.

Description

technical field [0001] The invention relates to the technical field of mobile communication, in particular to a method and device for sending and receiving system control messages. Background technique [0002] In a mobile communication system, UE (User Equipment) has two basic operating modes: idle mode and connected mode. The UE stays in the idle mode when it is powered on, and through the non-access stratum identification such as IMSI (International Mobile Subscriber Identity), TMSI (Temporary Subscriber Identity) or P-TMSI (Packet TemporaryMobile Subscriber Identity, packet temporary mobile subscriber identity), etc. signs to distinguish. UTRAN (Terrestrial Radio Access Network) does not store the information of UEs in idle mode, and can only page all UEs in a cell or all UEs at the same paging time. When the UE completes RRC (Radio Resource Control) connection establishment, the UE transitions from idle mode to connected mode. In the RRC connection mode of the UE, th...
