Abstract
The invention relates to a method for transmitting a paging message. The method comprises the following steps that: a node B periodically sends the paging message at a fixed moment by a physical downlink control channel (PDCCH); if the paging message received by user equipment UE comprises an identifier C-RNTI (Cell Radio Network Temporary Identifier) of the UE, ensuring the UE to enter a continuous monitoring state; or, ensuring the UE to be kept in an original state. After the method disclosed by the embodiment of the invention is applied, the paging process is simplified, so that resources are saved.
Description
Technical field
The present invention relates to communication technical field, more specifically, relate to a kind of method of transmitting paging information.
Background technology
In communication system, for idle pulley under terminal (UE) converse, need call terminal.For example, the paging in the LTE system may further comprise the steps:
UE under step 104, the idle pulley monitors the paging indication information in the down control channel (PDCCH) in the paging time.
If UE receives the paging indication information of PDCCH, then according to paging indication information paging receiving information in Physical Downlink Shared Channel (PDSCH).
Above-mentioned paging needs to coordinate each other between UE, MME and the eNodeB, and eNodeB not only need also will send beep-page message to UE through Traffic Channel through PDCCH; UE need calculate the paging time, monitors PDCCH information in the paging time then.The said process more complicated, and in whole paging, need take more Radio Resource.
Summary of the invention
The embodiment of the invention proposes a kind of method of transmitting paging information, simplifies paging, thereby economizes on resources.
The technical scheme of the embodiment of the invention is following:
A kind of method of transmitting paging information, this method comprises:
Node B is periodically sent paging information through down control channel PDCCH in fixed time;
If comprise the sign C-RNTI of UE in the paging information that user UE receives, then UE gets into the state of intercepting continuously;
Otherwise UE keeps original state.
Said fixed time is preset.
Frame number by paging information is confirmed said fixed time with preset N.
Said frame number by paging information confirms that with preset N said fixed time comprises:
Frame number in the paging information is obtained K to preset N delivery, and the frame that the frame number in the paging information is corresponding is as said fixed time, and K is a preset value.
The said cycle is confirmed by the traffic carrying capacity of system.
Can find out that from technique scheme in embodiments of the present invention, eNodeB periodically sends paging information through PDCCH in fixed time; If comprise the sign C-RNTI of UE in the paging information that user UE receives, then UE gets into and intercepts state continuously, does not need UE to calculate the paging time; Otherwise UE keeps original state.Owing to do not need UE itself to calculate the paging time, and beep-page message is that fixed time sends in PDCCH, and minimizing taking Traffic Channel, thereby economizes on resources.

Fig. 3 is the method idiographic flow sketch map of embodiment of the invention transmitting paging information.
Embodiment
For making the object of the invention, technical scheme and advantage express clearlyer, the present invention is remake further detailed explanation below in conjunction with accompanying drawing and specific embodiment.
In embodiments of the present invention, paging was carried out in the fixing moment, and paging information does not transmit in Traffic Channel, but directly transmits through PDCCH.Reduce taking Traffic Channel, avoided in the middle of the prior art, paging information also need transmit in Traffic Channel, thereby reduces the bit number of transmission.In addition,, need not UE and calculate the paging time, further economize on resources owing to periodically carry out the transmission of paging information.
Referring to accompanying drawing 2 are method flow sketch mapes of transmitting paging information, may further comprise the steps:
Step 201, eNodeB at fixed time, periodically send paging information through PDCCH.
UE inserts the sign C-RNTI that the back obtains UE at random.Send paging information if desired, then paging information only transmits in the fixing moment.Suppose that frame number is nf, then paging information only transmits in the frame of nf mod N=K, N wherein, and K is predefined value.
In the moment of sending beep-page message, eNodeB sends beep-page message in PDCCH.Need encode during paging, the coding of DCI is similar in cataloged procedure and the LTE system, but does not carry out the CRC coding.The C-RNTI value that comprises the plurality of paging user among each PDCCH.
Like this, paging information need not transmit in Traffic Channel, but directly transmits through PDCCH.Because UE need not calculate calling time, and in PCCCH, send paging information and no longer pass through CRC check, thereby simplify whole paging, saved resource to UE.
Step 202, UE get into continuous listening state.
UE detects paging information in the moment of sending beep-page message, need not carry out CRC check during detection.If comprise the C-RNTI of itself in the paging information that UE receives, think that then UE is paged.This UE is got into continuous listening state, to monitor the information of down control channel.
Step 203, UE keep original state.
If do not comprise the C-RNTI of self in the paging information that UE receives, then this UE is not paged, and this UE keeps original state.
Carry out detailed explanation with 230MHz frequency range national grid communication system below, specifically may further comprise the steps referring to accompanying drawing 3:
The channel architecture of 230MHz frequency range state electrical communication system and LTE's is similar, descending PDCCH and the Traffic Channel (PDSCH) of comprising.
UE obtains the sign C-RNTI of UE behind random access procedure.
The fixed time of step 302, transmission paging information.
ENodeB judges it is the fixed time that sends paging information, and then execution in step 303; Otherwise, execution in step 306,
This fixed time is to be confirmed with preset N by the frame number of paging information.Concrete, the frame number in the paging information is obtained K to preset N delivery, the frame that the frame number in the paging information is corresponding is as fixed time, and K is a preset value.
ENodeB periodically sends beep-page message through PDCCH.Comprise the C-RNTI that is sent out paged UE in the beep-page message.The cycle that eNodeB sends beep-page message is to be confirmed by the traffic carrying capacity of system.
Physical layer adopts fixing modulation coding mode to send to the content of beep-page message, and for saving the bit number that sends, physical layer needn't add the verification of CRC to beep-page message.
Include ID C-RNTI in the beep-page message that UE receives, then execution in step 305; Otherwise, execution in step 306.
The C-RNTI that UE self is arranged in the paging information that UE receives, then this UE is about to be scheduled, and gets into the state of intercepting continuously.
The C-RNTI of UE self is not arranged in the paging information that UE receives, and then this UE manages original state.
The above is merely preferred embodiment of the present invention, is not to be used to limit protection scope of the present invention.All within spirit of the present invention and principle, any modification of being done, be equal to replacement, improvement etc., all should be included within protection scope of the present invention.
