Description

Paging message transmission method and device

The present application claims priority to Chinese Patent Application No. 201410032078.1, entitled "Paging Message Transmission Method and Apparatus", filed on January 23, 2014, the entire contents of In the application.

Technical field

The present invention relates to the field of wireless communication technologies, and in particular, to a paging message transmission method and apparatus.

Background technique

1) M2M

Machine-to-machine (M2M) communication is a new communication concept. Its purpose is to combine many different types of communication technologies, such as machine-to-machine communication, machine control communication, human-computer interaction communication, Mobile internet communication to promote social production and lifestyle development. It is expected that the business of human-to-human communication in the future may only account for 1/3 of the entire terminal market, and a larger amount of communication is the inter-machine (small bandwidth system) communication service.

Current mobile communication networks are designed for communication between people, such as the determination of network capacity. If you want to use mobile communication networks to support small-bandwidth system communication, you need to optimize the mechanism of the mobile communication system according to the characteristics of small-bandwidth system communication, so that when traditional human-to-human communication is not affected or less affected. To better achieve small bandwidth system communication.

Some features that may be present in the currently recognized MTC communication are: the MTC terminal has low mobility; the time for data transmission between the MTC terminal and the network side is controllable; that is, the MTC terminal can only access within a specified time period of the network. The data transmission performed by the MTC terminal and the network side does not require high real-time performance, that is, it has time tolerance; the MTC terminal has limited energy and requires extremely low power consumption; only small data amount information is transmitted between the MTC terminal and the network side. Transmission; the MTC terminal can be managed in units of groups; an actual MTC terminal can have one or more of the above characteristics.

In the third generation mobile communication system and its Long Term Evolution (LTE), it is necessary to support the Machine Type Communications (MTC) function. An MTC device (MTC terminal) may have some of the characteristics of various M2M communication characteristics, such as low mobility, small amount of transmitted data, insensitivity to communication delay, and extremely low power consumption.

2) Coverage enhancement technology for M2M transmission

In the existing GSM-based M2M network, operators find that terminals working in some scenarios, such as terminals working in basements, shopping malls, or building corners, are severely damped due to severe occlusion of wireless signals. Subtract, the above terminal can not communicate with the network, and the deep coverage of the network for these scenarios will greatly increase the network construction cost. The operator has been tested and believes that it is necessary to enhance the existing coverage of GSM by 15 dB to meet the coverage requirements of the above scenarios. Subsequent LTE technology will replace GSM for M2M transmission. Since LTE and GSM coverage are basically the same, LTE technology also needs to enhance 15dB coverage to meet the M2M transmission requirements in the above scenario.

3) Mechanism for the terminal to receive paging messages in the LTE system

The network can send a page to the UE in the idle state and the connected state. The paging process may be triggered by the core network to notify a certain UE to receive a paging request, or triggered by the eNB, to notify the system information update, and notify the UE to receive an Earthquake and Tsunami Warning System (ETWS) or Information such as the Commercial Mobile Alert Service (CMAS). In particular, for the MTC terminal in the connected state, the paging message is mainly used to inform the terminal system of the update of the message.

The current LTE protocol stipulates that the paging message is scheduled by the Physical Downlink Control Channel (PDCCH) scrambled by the Radio Network Temporary Identifier (P-RNTI), and is in the physical downlink shared channel (Physical Downlink Shared). Channel (PDSCH) transmission (can be scheduled anywhere in the downlink data bandwidth); a paging message can page up to 16 users, and the paging message contains the terminal paging identifier of each paged user.

According to the capacity requirement, paging messages can be configured to transmit different paging messages in 1 or 2 or 4 subframes in each radio frame, as shown in Table 2a and Table 2b.

For power saving reasons, the paging reception of the UE follows the discontinuous reception (Discontinuous Reception (DRX) principle of discontinuous reception. As shown in Figure 1, each cell broadcasts a default DRX paging cycle of the cell to all UEs in the cell in the system information. Each UE can also set the UE according to its own power and paging system messages. The predetermined DRX cycle is to send the UE-specific DRX cycle to the MME through a Non-Access Stratum (NAS) message Attach Request or TAU Request. The MME delivers the specific DRX information of the paged UE to the eNB through a paging message of the S1 Application Protocol (S1AP). The eNB has both the specific DRX information used by each UE received from the MME and the default DRX paging cycle of the system information broadcast. The UE receives the default DRX paging cycle broadcasted in the system information, and may also configure its own specific DRX.

If the UE and the eNB maintain two pairs of the same paging DRX configuration (the default DRX paging cycle and the UE-specific DRX), the same rule is used to filter out one of the pair as the paging T period T. Therefore, the paging cycle configuration of the eNB and the UE can always be matched. The eNB sends a paging message to the UE in the air interface according to the paging cycle and the paging time, and the UE can receive the corresponding correct paging moment.

The UE and the network side calculate the UE identity (UE ID) through the UE's own International Mobile Subscriber Identity (IMSI), and use the same paging cycle T to calculate the paging time (system frame number) at which the UE is located. (System Frame Number, SFN) + subframe position i_s), the specific formula is as follows:

In a paging cycle T, the location of the radio frame in which the paging message is located is:

SFN mod T=(T div N)*(UE_ID mod N)

In the radio frame in which the paging message is located, the subframe in which the paging message is located is determined according to the i-s and table 2 calculated by the following formula.

I_s=floor(UE_ID/N)mod Ns

Where div means divide operation, mod means remainder operation, and floor is rounding down.

The parameters involved in the above two formulas are calculated as follows:

nB: 4T, 2T, T, T/2, T/4, T/8, T/16, T/32, configuring one nB for each paging message;

N:min(T,nB)

Ns:max(1,nB/T)

UE_ID: IMSI mod 1024.

During each paging cycle, the UE only listens to the paging information in a subframe position determined based on the foregoing rule, receives the public notification information therein, and searches for whether it includes its own Paging UE ID, which may be international. International Mobile Subscriber Identity (IMSI) or System Architecture Evolution Temporary Mobile Station Identifier (S-TMSI).

To achieve 15dB coverage enhancement, a more feasible method is to use repeated transmission techniques such as LTE system existing channels, for example, dozens to hundreds of repetitions can achieve 15dB coverage enhancement. However, with the transmission mechanism of the existing paging message, the UE monitors the paging information only in the corresponding one subframe position in each paging cycle, and there is no repeated transmission mechanism of the paging message, so the terminal that needs coverage enhancement cannot be used. Paging messages transmitted based on existing mechanisms are correctly received.

The paging message transmission method and apparatus provided by the present invention will be described in more detail below with reference to the accompanying drawings and embodiments.

In order to solve the coverage problem of M2M transmission, a potentially more direct and feasible method is to repeat transmission of an existing physical channel or the like, and theoretically, it can be obtained by performing tens to hundreds of repeated transmissions on an existing physical channel. 15dB coverage gain.

The first embodiment of the present invention provides a paging message transmission mechanism that supports repeated transmission of paging messages, which can implement coverage enhancement and solve the coverage problem of M2M transmission.

As shown in FIG. 2, on the network side, the paging message transmission method provided in Embodiment 1 of the present invention includes:

Step 201, determining the total number of repeated transmissions M of the paging message in the paging period T, and the number n of repeated transmissions on each radio frame;

Specifically, the number M of repeated transmissions of the paging message may be determined according to the coverage enhancement target, such as 15 dB.

Specifically, the total number of repeated transmissions M of the paging message in the paging period T may be determined according to the manner agreed by the protocol; or the total number of repeated transmissions M of the paging message in the paging period T may be determined according to the paging requirement, and The total number of repeated transmissions M of the determined paging message in each paging cycle T is notified to the UE by higher layer signaling.

Step 202: Determine a start reference radio frame time difference configuration parameter in the initial reference radio frame calculation formula, and notify the UE of the determined initial reference radio frame time difference configuration parameter, where the determined initial reference radio frame time difference configuration parameter corresponds to Initial reference radio frame time difference D, not less than

Radio frames;

Preferably, the network side notifies the terminal of the determined initial reference radio frame time difference configuration parameter by using high layer signaling, and of course, other manners may also be adopted.

The calculation formula of the radio frame in which the paging message is located in the existing protocol may be used, or may be adjusted based on the calculation formula of the radio frame in which the paging message is located in the existing protocol.

The initial reference radio frame time difference D corresponding to the initial reference radio frame time difference configuration parameter indicates how long after the start reference radio frame does not occur another start reference radio frame.

In the embodiment of the present invention, D is not less than

Radio frames, that is, the start reference radio frame determined by initiating the reference radio frame time difference configuration parameter, so that D-1 radio frames after the start reference radio frame are not used as the starting reference for another paging message. Wireless frame use. In this way, the radio frames or subframes occupied by the repeated transmission of two adjacent different paging messages can be made to overlap each other.

Step 203: Determine a starting reference radio frame of the paging message according to the determined initial reference radio frame time difference configuration parameter.

Specifically, the initial reference radio frame of the paging message is determined according to the initial reference radio frame calculation formula.

Step 204: Determine, according to the determined initial reference radio frame, M and n, a subframe in which the paging message is repeatedly transmitted.

Since the initial reference radio frame is determined and the D-1 radio frames are not used as the starting reference radio frame of another paging message after the initial reference radio frame, the initial reference radio frame can be used. And in the following D-1 radio frames, according to the number n of repeated transmissions on each radio frame, the subframe in which the paging message is repeatedly transmitted is determined, so that the total number of repeated transmissions reaches M.

Step 205: Send the paging message at each determined subframe position by using a repeated physical downlink shared channel PDSCH.

The paging message transmission method provided by the embodiment of the present invention solves the problem of repeated transmission of the coverage enhanced paging message. When the network side uses the method to transmit the paging message, the D- after the reference radio frame starts from the beginning of the paging message. N radio frames are not used as the starting reference radio frame of another paging message, so two different adjacent paging messages do not overlap in transmission time, which can simplify the system scheduling problem.

As shown in FIG. 3, on the terminal side, the first embodiment of the present invention provides a method for a UE to receive a paging message, including:

Step 301, determining the total number of repeated transmissions M of the paging message in the paging period T, and the number n of repeated transmissions on each radio frame;

Specifically, the total number of repeated transmissions M of the paging message in the paging period T may be determined according to the manner agreed by the protocol or according to the notification on the network side.

Step 302: Receive a start reference radio frame time difference configuration parameter in a start reference radio frame calculation formula sent by the network side, where the initial reference radio frame time difference configuration parameter corresponding to the received start reference radio frame time difference configuration parameter is not less than

Radio frames;

Step 303: Determine a starting reference radio frame of the paging message according to the received initial reference radio frame time difference configuration parameter.

Step 304: Determine, according to the determined initial reference radio frame, M and n, a subframe in which the paging message is repeatedly transmitted.

Step 305: Receive a paging message at each determined subframe position by using a repeated physical downlink shared channel PDSCH.

The paging message transmission method provided by the first embodiment of the present invention solves the problem of repeated transmission of the coverage enhanced paging message. When the UE receives the paging message by using the method, the D- after the reference radio frame starts from the beginning of the paging message. Neither radio frame is used as the starting reference radio frame for another paging message, so different two adjacent paging messages do not overlap in transmission time.

On the network side and the terminal side, the calculation formula of the radio frame in which the paging message is located in the existing protocol may be used, or may be adjusted based on the calculation formula of the radio frame in which the paging message is located in the existing protocol. A specific implementation of how to determine the initial reference radio frame time difference configuration parameter is given below.

1) Determination method of initial reference radio frame time difference configuration parameter

Both the network side and the terminal use the calculation formula of the radio frame in which the paging message is calculated in the existing protocol.

The calculation formula of the initial reference radio frame PF_ref is specifically:

SFN mod T=(T div N)*(UE_ID modN)

SFN is the system frame number of the starting reference radio frame;

T is the paging message period;

The UE_ID is determined according to the international mobile subscription identifier IMSI of the UE that is paged by the paging message, and according to the existing protocol, the UE_ID is the IMSI mod 1024;

nB_CE is a starting reference radio frame time difference configuration parameter;

nB_CE is a value in the set T/2 ^m , and m is an integer not less than 0, that is, nB_CE is selected from T, T/2, T/4, T/8, T/16, T/32... a value

N:min(T, nB_CE).

The T/N in the existing protocol formula represents the time difference between the paging radio frame calculated by the N and the next paging radio frame, such as T/N=4, which does not represent the three radio frames after the paging radio frame. Another paging radio frame will appear.

Based on this, the initial reference radio frame time difference D corresponding to nB_CE is T/nB_CE radio frames. In the embodiment of the present invention, M<=n*(T/nB_CE), so that D-1 radio frames after the start reference radio frame PF_ref are not used as the starting reference radio frame of another paging message. Therefore, the radio frame can be selected to complete the transmission of the paging message in the radio frame PF_ref and thereafter (T/nB_CE)-1 radio frames.

Preferably, M=n*(T/nB_CE) can be agreed upon by the agreement.

2) Determination method of initial reference radio frame time difference configuration parameter

Based on the calculation formula of the radio frame in which the paging message is calculated in the existing protocol, the calculation formula for calculating the radio frame PF_ref is obtained.

The calculation formula of the initial reference radio frame PF_ref adopted by the network side and the terminal is specifically:

SFN mod T=floor[((T div N)*(UE_ID mod N))div div X]*X

SFN is the system frame number of the initial reference radio frame, T is the paging message period, and UE_ID is determined according to the international mobile subscription identifier IMSI of the UE paged by the paging message, N=min(T, nB), nB is a set. A value in [4T, 2T, T, T/2, T/4, T/8, T/16, T/32], where X is the initial reference radio frame time difference configuration parameter.

Preferably, M=n*X can be agreed upon by the agreement.

The network side and the terminal determine the specific implementation manner of the subframe in which the paging message is transmitted:

Situation one

The initial reference radio frame time difference D corresponding to the determined initial reference radio frame time difference configuration parameter is equal to

Radio frames, ie M=n*(T/nB_CE) or M=n*X.

Selecting to occupy the initial reference radio frame and the following D-1 radio frames, that is, occupying all radio frames that can be used for the paging message transmission;

N different subframes are selected on each occupied radio frame as the subframe in which the paging message is transmitted.

Situation two

Radio frames, M<n*(T/nB_CE) or M<n*X.

The radio frames that can be used for the paging message transmission are more than the radio frames required to implement the M transmissions, and therefore occupy some of the available radio frames. In this case, the predetermined reference radio frames can be determined according to predefined rules. After D-1 radio frames, choose to occupy them.

Radio frames. Specifically, it can be

Wireless frames or after

Radio frames or any selected

Radio frames. The same predefined rules should be used on the network side and the terminal side. That is, which radio frames are occupied may be predefined or determined by a predefined pattern pattern.

N different subframes are selected on each occupied radio frame as the subframe in which the paging message is repeatedly transmitted.

Based on the foregoing determining the radio frame occupied by the paging message, the network side and the terminal may determine n subframes for paging message transmission on each radio frame as follows:

1) The network side and the terminal agree to adopt the same predetermined selection mode, and select n different subframes on each occupied radio frame as the subframe in which the paging message is repeatedly transmitted;

2) Determined by the network side, the network side selects n different subframes on each occupied radio frame as the subframe in which the paging message is repeatedly transmitted, and selects the subframe information selected on each occupied radio frame. Notify the UE. The network notifies the terminal which subframes are specifically occupied by a terminal in one radio frame.

The subframe occupation mode determined by the network side, or the predetermined selection manner agreed by the network side and the terminal, may be, but is not limited to, As follows:

When n=1, the parameter i_s is determined by the formula: i_s=floor(UE_ID/N) mod Ns

The UE_ID is determined according to the international mobile subscription identifier IMSI of the UE that is paged by the paging message, that is, the UE_ID is IMSImod 1024, N=min(T, nB), Ns=max(1, nB/T), and nB is a set [4T , a value in 2T, T, T/2, T/4, T/8, T/16, T/32], T is the paging message period, floor is the downward remainder operation, and mod is the remainder operation. .

or

For example, when i_s=4, the position of the first subframe is determined by i_s=0 and Table 2, and the other subframes are subframes corresponding to i_s=1, 2, and 3.

It should be noted that, in the foregoing embodiment, a method for determining a plurality of subframes occupied by repeated transmission of paging messages is provided. Here, the determined plurality of subframes may be a plurality of subframes occupied by a PDSCH channel carrying a paging message. For the network side, as a preferred implementation, the paging message is sent by using the PDSCH in each determined subframe position, which specifically includes:

In each occupied subframe, the PDSCH transmission adopts a predefined transmission mode, that is, adopts a predefined physical resource block PRB, a transmission block size TBS, a modulation mode, or selects a plurality of predefined transmission modes. One of them is to select one of a plurality of sets of transmission modes consisting of a plurality of predefined PRBs, TBSs, and modulation modes.

In this embodiment, the repeatedly transmitted PDSCH channel may not be scheduled using PDCCH.

For the network side, as another preferred implementation manner, the repeatedly transmitted PDSCH channel may adopt PDCCH scheduling, and the radio frame and the subframe position of the PDCCH channel may be determined according to a timing relationship between the PDCCH and the PDSCH: adopting a physical downlink control channel PDCCH, The repeated PDSCH is scheduled, and the last subframe in which the PDCCH is located is the kth subframe before the start subframe where the PDSCH is located, and k is a positive integer.

Correspondingly, on the terminal side, as a preferred implementation manner, the receiving, by using the PDSCH, the paging message in each determined subframe position, specifically includes:

On the terminal side, as another preferred embodiment, the scheduling information of the PDSCH determined by the physical downlink control channel PDCCH, the last subframe in which the PDCCH is located is the kth sub-frame before the start subframe where the PDSCH is located Frame, k is a positive integer;

The paging message is received at each determined subframe position by the PDSCH according to the scheduling information of the PDSCH.

For the network side, sending the paging message on each determined subframe position includes:

Receiving the paging message on each of the determined subframe positions on the terminal side, specifically:

The second embodiment of the present invention further provides a paging message transmission method, as shown in FIG. 4, including:

Step 401, determining the total number of repeated transmissions M of the paging message in the paging period T, and the number n of repeated transmissions on each radio frame;

Step 402: Determine a start reference radio frame time difference configuration parameter in the initial reference radio frame calculation formula, notify the user equipment UE of the determined initial reference radio frame time difference configuration parameter, and determine the initial reference radio frame time difference configuration parameter. Corresponding initial reference radio frame time difference D, not less than

Radio frames;

Step 403: Determine, according to the determined initial reference radio frame time difference configuration parameter, a starting reference radio frame of a physical downlink control channel PDCCH that schedules a paging message.

Step 404: Determine, according to the determined PDCCH start reference radio frame, M and n of the scheduled paging message, a subframe in which the PDCCH scheduling the paging message is located;

Step 405: Determine a radio frame in which the kth subframe after the last subframe in which the PDCCH of the paging message is located is the initial reference radio subframe of the paging message, where k is a positive integer;

Step 406: Determine, according to the initial reference radio frame, M and n of the determined paging message, a subframe in which the paging message is transmitted;

Step 407: The paging message is transmitted at each determined subframe position by using a physical downlink shared channel PDSCH.

The second embodiment of the present invention further provides a method for transmitting a paging message received by a UE, as shown in FIG. 5, including:

Step 501, determining the total number of repeated transmissions M of the paging message in the paging period T, and the number n of repeated transmissions on each radio frame;

Step 502: Receive a start reference radio frame time difference configuration parameter in a start reference radio frame calculation formula sent by the network side, where the initial reference radio frame time difference configuration parameter corresponding to the received start reference radio frame time difference configuration parameter is not less than

Radio frames;

Step 503: Determine, according to the received initial reference radio frame time difference configuration parameter, a starting reference radio frame of a physical downlink control channel PDCCH that schedules a paging message.

Step 504: Determine, according to the determined PDCCH start reference radio frame, M and n of the scheduled paging message, a subframe in which the PDCCH scheduling the paging message is located;

Step 505: Determine a radio frame in which the kth subframe after the last subframe in which the PDCCH of the paging message is located is the initial reference radio subframe of the paging message, where k is a positive integer;

Step 506: Determine, according to the determined reference radio frame, M and n of the determined paging message, a subframe in which the paging message is transmitted;

Step 507: Receive a paging message at each determined subframe position by using a physical downlink shared channel PDSCH.

The difference between this embodiment and the first embodiment is that the multiple subframes determined based on the foregoing mechanism are repeated subframes for scheduling the control channel PDCCH channel of the PDSCH channel carrying the paging message. At this time, the radio frame and the subframe position of the PDSCH channel carrying the paging message may be determined according to a timing relationship between the PDCCH and the PDSCH: the timing relationship may determine that the repeated PDCCH is transmitted before the PDSCH k subframes.

Therefore, the manner of determining the subframe in which the PDCCH of the paging message is scheduled in this embodiment is determined in the same manner as the subframe in which the paging message is transmitted in the foregoing embodiment, and details are not described herein.

On the basis of determining the paging message starting reference radio frame, the embodiment determines the subframe in which the paging message is transmitted according to the initial reference radio frame, M and n of the determined paging message, as described in the foregoing embodiment. Detailed description is not repeated here.

The time difference between two adjacent paging subframes in one paging cycle in the existing paging mechanism is at least 1 subframe. In this case, if the paging time is directly transmitted by the terminal according to the paging time calculated by the existing mechanism as the starting point of the repeated transmission, the transmission of multiple paging messages at the adjacent paging moment will be in the same subframe. Overlap, which makes the scheduling of the system more complicated, and the system is not likely to configure so many PDCCHs in the same subframe to schedule the multiple paging messages to be transmitted in the same subframe; in addition, to distinguish multiple in the same subframe The paging message may also require the system to configure multiple P-RNTIs.

The invention provides a transmission mechanism of a repeatedly transmitted paging message, the main idea of which is that the network determines the number of repeated transmissions of the coverage enhanced paging message; and determines the coverage enhanced paging message based on the repeated transmission times of the paging message network. The initial reference radio frame time difference configuration parameter of the transmission determines a plurality of subframes in which the paging message is repeatedly transmitted based on the determined parameters and predefined rules. By adopting the method proposed by the present invention, the problem of repeated transmission of the coverage enhanced paging message can be solved, and the method for scheduling the paging message by the network is relatively simple, and since the two adjacent paging messages do not overlap in the transmission time, The control channel PDCCH and data channel PDSCH for transmitting paging messages require only one P-RNTI scrambling.

Based on the same inventive concept, an embodiment of the present invention further provides a paging message transmission apparatus. Since the principle of solving the problem is similar to a paging message transmission method, the implementation of the apparatus can be implemented by referring to the method. It will not be repeated here.
