Description

Paging method, device and system

technical field

The present invention relates to communication technology, in particular to a paging method, an uplink data sending method, an access method, equipment and a system.

Background technique

With the development of mobile communication technology, the large-scale deployment of 3G (3rd-generation, third-generation mobile communication technology) network or LTE (Long Term Evolution, long-term evolution) network, high-speed and large-bandwidth services bring people a variety of app experience. The large-scale growth of smart phones has brought more challenges to operators, and the continuous growth of application services has led to an increasing demand for network capacity. In order to further enhance the capacity of the network, the network architecture evolves from a homogeneous network to a heterogeneous network. For example, as shown in FIG. 1 , one macro base station 1 is often covered by multiple access nodes 2 . These access nodes 2 can be small base stations Pico, indoor base stations Femto, low mobility base stations LoMo, local wireless access points AP, low power transmitting nodes (Low Power Node, LPN), etc., none of which have the ability to send paging messages function. The macro base station sends a paging message to the user equipment (User Equipment, UE) to notify the UE that a service is coming.

In the existing LTE network, the macro base station sends paging messages according to certain rules, and the UE will also monitor its own paging messages according to the rules. The paging information sent by the macro base station is defined from the perspective of the frame format. It is composed of wireless frames. As shown in Figure 2, each wireless frame contains 10 subframes, and each subframe contains several OFDM (Orthogonal Frequency Division Multiplexing, orthogonal frequency division multiplexing) symbols. Subframe numbers 0~9, wireless frame numbers 0~665365.

The macro base station only sends a paging message to the UE once in a paging cycle. The macro base station sends a paging message to the UE at a listening position (Paging Occasion, PO) of a specified radio frame (Paging Frame, PF) according to a rule. For the UE, within a paging cycle, the UE also receives the paging message once at the PO of the designated PF according to the rule. Wherein, PO is the subframe number of the subframe in the radio frame. Specifically, this rule specifies that the calculation method of PF frame number and PO subframe number is as follows:

SFN mod T=(T div N)×(UE_ID mod N)

i_s=floor(UE_ID/N) mod Ns

Among them, the value of SFN is the PF frame number, T is the paging cycle of the UE, N is equal to min(T, nB), and the minimum value between T and nB is taken, and the unit is a radio frame. nB is broadcast by the network in System Information Blocks 2 (System Information Blocks2, SIB2), and its value range is 4T, 2T, T, T/2, T/4, T/8, T/16, T/32, The unit is a radio frame. UE_ID is equal to International Mobile Subscriber Identification Number (IMSI) modulo 1024. Ns is equal to max(1, nB/T), taking the maximum value between 1 and nB/T. According to the above explanation of the value range of nB, the value range of Ns is 1, 2, 4. i_s is the PO index value. According to the definition in the LTE standard, there is a fixed mapping relationship between i_s and subframes, as shown in Table 1 and Table 2 below.

As shown in Table 1, in Frequency Division Duplexing (Frequency Division Duplexing, FDD) mode, the paging subframe in LTE is at least one of the following: the first subframe (subframe #0) of the radio frame, the fifth subframe (subframe #4), the sixth subframe (subframe #5), and the tenth subframe (subframe #9).

Table 1 FDD paging subframe configuration table

As shown in Table 2, in Time Division Duplexing (TDD) mode, the paging subframe in LTE is at least one of the following: the first subframe (subframe #0) of the radio frame, the second subframe (subframe #1), sixth subframe (subframe #5), seventh subframe (subframe #6).

Table 2 TDD paging subframe configuration table

Wherein, in Table 1 and Table 2, PO can be understood as a paging subframe, that is, the listening position of the UE is on this subframe. For a time division duplex system, paging information is transmitted on one or more subframes in subframes 0, 1, 5, and 6 of each radio frame; for a frequency division duplex FDD system, paging information is transmitted in each radio frame Transmit on one or more subframes of subframes 0, 4, 5, and 9, and no information is transmitted on other subframes.

In the prior art, the base station is in the working state during the entire period of the paging cycle, so the base station only needs to transmit the paging message in the above-mentioned few subframes by adopting the above rules, and other subframes are idle, which wastes a lot of resources. , high energy consumption.

Detailed ways

In order to make the purpose, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments It is a part of embodiments of the present invention, but not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without creative efforts fall within the protection scope of the present invention.

As shown in FIG. 3 , it is a schematic flowchart of the paging method provided by Embodiment 1 of the present invention. As shown in FIG. 3, the paging method according to Embodiment 1 of the present invention includes:

Step 101: Send a paging message to the user equipment during the active period of the discontinuous transmission period or within the transmission period indicated by the transmission indication information of the preset pattern.

Among them, the base station works in the discontinuous transmission mode, that is, according to the discontinuous transmission period, it sends paging messages to the user equipment in a part of the period in the period, and is in a dormant state in the remaining part of the time period, that is, it does not send paging messages to the user equipment. information. Wherein, a part of the time period during which the base station sends a paging message may be called an active period, and the time period during which the base station is in a dormant state may be called a dormant period. For example, according to the discontinuous transmission period, the base station turns on the downlink transceiver for sending paging messages to user equipment during the active period, so as to send paging messages to user equipment during the active period, and during the dormant period During the sleep period, the downlink transceiver used to send the paging message to the user equipment is turned off, so that the base station stops sending the paging message to the user equipment during the sleep period. Specifically, the Discontinuous Transmission (DXT) cycle is generally defined in the prior art as including two time periods, the first continuous time period constitutes a fixed activation period 4 (also called Active Mode), and the latter continuous time period Constitute a fixed dormant period 5 (also known as Opportunity DXT), as shown in Figure 4a. However, in practical applications, for special needs, it is also possible to forcefully set a period of time as the mandatory activation period 6 in the post-continuous time period defined in the prior art, as shown in Figure 4b, so that the base station can Turn on the downlink transceiver in order to send the paging message to the user equipment. Therefore, as shown in FIG. 4a, the activation period of the discontinuous transmission period may be a fixed activation period 4 of the discontinuous transmission period. Or, as shown in FIG. 4b, the activation period of the discontinuous transmission cycle includes: the fixed activation period 4 of the discontinuous transmission cycle and the mandatory activation period 6 set in the fixed sleep period 5 of the discontinuous transmission cycle . Wherein, the mandatory activation period 6 is less than or equal to the fixed dormant period 5 . What needs to be explained here is: the setting of the mandatory activation period is not fixed. In the current cycle, the mandatory activation period may be equal to the fixed dormant period, but in the next cycle, the mandatory activation period may less than the fixed dormant period. The activation period of the discontinuous transmission period may be shorter than the paging period described in the prior art, that is, the time for the base station to send a paging message to all user equipments within its tracking area.

There is at least one sending instruction information of the preset pattern, and each sending instruction information corresponds to a preset sending period within a preset period. Specifically, the preset pattern may be characterized as a string of character strings or a symbol string composed of other identification symbols. For example, character 1 is used to represent sending instruction information, and character 0 is dormancy instruction information. The preset pattern can be characterized as: a character string of 0100001000. Assuming that the preset period is 10ms, the time period identified by each character in the preset pattern is 1ms. The position marked as 1 is the sending instruction information, indicating that the base station can send the paging message within the sending period indicated by the sending instruction information, that is, within 1 ms. The position marked as 0 is the dormancy indication information, indicating that the base station is in a dormancy state during the dormancy period indicated by the dormancy indication information. In fact, the transmission indication information of the preset pattern may be wireless frame level indication information, for example, the character 1 in the character string represented by the preset pattern mentioned above corresponds to the wireless frame level indication information, and the wireless frame level indication The information corresponds to a radio frame within a preset period, and the base station can send a paging message to the user equipment within the radio frame. Alternatively, the transmission indication information of the preset pattern may be subframe level indication information, for example, the character 1 in the character string represented by the preset pattern enumerated above corresponds to the subframe level indication information, and the subframe level indication information Corresponding to a subframe within a preset period, the base station may send a paging message to the user equipment on the subframe.

Step 102: Send monitoring indication information to the user equipment, so that the user equipment determines a monitoring position according to the monitoring indication information, and monitors a paging message at the monitoring position.

Specifically, if a paging message is sent to the user equipment during the activation period of the discontinuous transmission period, then the monitoring indication information carrying the discontinuous transmission period parameter and the pre-configured paging parameter is sent to the user equipment; or, to the user equipment The user equipment sends monitoring indication information carrying the sending location of the paging message; or, sending the user equipment activation period information carrying a discontinuous sending period and used to instruct the user equipment to use a specified subframe as monitoring Location monitoring indication information, wherein the specified subframe is a subframe within the active period of the previous or subsequent discontinuous transmission period closest to the monitoring location determined by the user equipment itself.

Further, the specified subframe may also be a subframe that is the same as the listening position determined by the user equipment itself in the activation period of the previous or subsequent discontinuous transmission period closest to the listening position determined by the user equipment itself number of subframes. Alternatively, the specified subframe may also be a subframe number separated from the listening position determined by the user equipment itself during the activation period of the previous or subsequent discontinuous transmission cycle closest to the listening position determined by the user equipment itself. subframe number of subframes. Wherein, the listening position determined by the user equipment itself may be the listening position obtained from the paging position configuration information that the base station is not in the discontinuous transmission cycle state for the equipment to send based on system message broadcast or dedicated signaling, or The user equipment is determined by using the PF and PO position determination rules in the prior art. For details, refer to the background art, which will not be repeated here.

If the paging message is sent to the user equipment within the sending period indicated by the sending instruction information of the preset pattern, then the monitoring instruction information carrying the sending location for sending the paging message is sent to the user equipment. Wherein, the sending position of the paging message mentioned in the above content includes: the frame number of the radio frame to which the subframe used to send the paging message belongs and/or the subframe number of the subframe.

In this embodiment, the base station only sends the paging message during the active period of the discontinuous transmission period or during the transmission period indicated by the transmission indication information of the preset pattern, and sends the paging message during the inactive period of the discontinuous transmission period or during the period of the preset pattern The base station is in a dormant state during the preset period except for the sending period indicated by sending the indication information. Based on the paging method provided in this embodiment, on the one hand, the base station controls the paging messages to be sent within the activation period of the discontinuous transmission period or within the transmission period indicated by the transmission indication information of the preset pattern, so that the paging message can be fully Using the time resources in the transmission period avoids the waste of time resources caused by only using a limited number of specific subframes in the radio frame of the paging cycle in the prior art; There is a dormant period within the preset period of the preset pattern or in the time other than the sending period indicated by the sending instruction information, which reduces the energy consumption of the base station.

As shown in FIG. 5 , it is a schematic flowchart of the paging method provided by Embodiment 2 of the present invention. As shown in FIG. 5, the second embodiment is a paging method in which a base station sends a paging message to a user equipment during a fixed activation period of a discontinuous transmission period, including:

Step 201, the base station acquires the DTX cycle, the fixed activation period of the DTX cycle, the device identifier of the user equipment, the actual paging cycle of the user equipment, and pre-configured paging parameters.

Step 202, the base station according to the discontinuous transmission period, the fixed activation period of the discontinuous transmission period, the pre-configured paging parameters, the device identifier of the user equipment and the actual paging period of the user equipment and determining a subframe number of a subframe used to send the paging message and a frame number of a radio frame to which the subframe belongs within a fixed active period of the discontinuous transmission period.

Specifically, firstly, the base station, according to the discontinuous transmission period, the fixed active period of the discontinuous transmission period, the pre-configured paging parameters, the equipment identifier of the user equipment, and the actual paging time of the user equipment The paging cycle is to determine the frame number of the radio frame to which the subframe used to send the paging message belongs during the fixed active period of the discontinuous sending cycle.

The determination process of the frame number is as follows:

Step S1, according to the device identifier of the user equipment, the actual paging cycle of the user equipment and the pre-configured paging parameters, the initial value of the frame number is calculated using the following first formula:

SFN mod T=((T div N)×(UE_ID mod N)

Among them, N=min(T, nB), SFN is the initial value of the frame number, T is the actual paging cycle of the user equipment, UE_ID is the device identifier of the user equipment, and nB is the preconfigured paging cycle Parameters, div means the integer operation of taking the quotient, mod means taking the modulo operation, min(*, *) means taking the minimum of two numbers. The usual value range of nB is {4T, 2T, T, T/2, T/4, T/8, T/16, T/32}. This value range is only an example, and the embodiment of the present invention not only Limited to this, the nB may also take other values. The actual paging cycle of the user equipment may be a discontinuous transmission cycle in which the user equipment works in a discontinuous transmission mode.

Step S2, according to the initial value of the frame number, the actual paging cycle of the user equipment, the discontinuous transmission cycle, and the fixed activation period of the discontinuous transmission cycle, the base station uses a preset mapping rule to map the The initial value of the frame number is mapped to the frame number corresponding to the fixed active period of the discontinuous transmission cycle, and the frame number is the frame number of the radio frame to which the subframe used by the base station to send the paging message belongs.

Wherein, the preset mapping rule may specifically be the following second formula:

SFN'=floor(SFN/T ₂ )×T ₂ +(SFN mod T)mod T ₁

Wherein, the SFN' is the frame number of the radio frame to which the subframe used by the base station to send the paging message belongs, SFN is the initial value of the frame number, _T1 is the fixed activation period of the discontinuous transmission cycle, and T ₂ is the discontinuous transmission cycle, T is the actual paging cycle of the user equipment, and floor(*) represents the largest integer less than or equal to the specified expression *; the actual paging cycle of the user equipment can be the The discontinuous transmission cycle in which the user equipment works in the discontinuous transmission mode.

Alternatively, the preset mapping rule may specifically be the following third formula:

SFN'=floor(SFN/T ₂ )×T ₂ +F((SFN mod T)×(T1/T))

Among them, F(*) means to take an integer greater than, less than or closest to the specified expression *;

Alternatively, the preset mapping rule may specifically be the following fourth formula:

SFN'=floor(SFN/T ₂ )×T ₂ +F((SFN mod T)×(T1/T)×(1/floor(T/T ₂ )));

Alternatively, the preset mapping rule may specifically be the following fifth formula:

SFN'mod T ₂ =floor((T ₁ /N')×(UE_ID mod N'))

Wherein, N'=T or T ₂ .

Further, the calculation starting point of the specific implementation formulas of the multiple mapping rules listed in the above embodiment all start at the position of SFN=0, while in practical applications, the starting point of the activation period of the discontinuous transmission cycle is It may not be at the position where SFN=0, and there is an offset value at this time, and the offset value has been determined and stored when the base station is configured in the discontinuous transmission working mode. Therefore, when the base station determines that there is an offset value, the base station needs to use the following correction method to correct each mapping rule formula in the above embodiment. Specifically, the correction process is as follows:

Step S3, the base station acquires a start time offset value of the activation period of the discontinuous transmission period.

Step S4, the base station corrects the frame number of the radio frame to which the subframe used to send the paging message belongs according to the start time offset value.

Specifically, the base station uses the following ninth formula to correct the frame number of the radio frame to which the subframe used to send the paging message belongs according to the start time offset value:

SFN”=floor((SFN’×10+P0+dtxStartOffset)/10)

Wherein, SFN" is the corrected frame number of the radio frame to which the subframe used to send the paging message belongs, SFN' is the frame number of the radio frame to which the subframe used to send the paging message belongs, and P0 is the frame number of the radio frame to which the subframe used to send the paging message belongs. For the subframe number of the subframe in which the paging message is sent, dtxStartOffset is the start time offset value.

Then, according to the discontinuous transmission period, the fixed activation period of the discontinuous transmission period, the pre-configured paging parameters, the device identifier of the user equipment, and the actual paging period of the user equipment, the base station, Determine the subframe number of the subframe used to send the paging message in the fixed active period of the discontinuous sending period.

The determination process of the subframe number is as follows:

Step S5, according to the actual paging cycle of the user equipment, the pre-configured paging parameters, the discontinuous transmission cycle and the fixed activation period of the discontinuous transmission cycle, the following sixth formula is used to calculate the first index value :

Ns=max(1，(nB/T)×F(T ₂ /T ₁ ))

Alternatively, the first index value is calculated using the following seventh formula:

Ns=max(1, (nB/T)×(T ₂ /T ₁ )×(T/T ₂ ))

Wherein, Ns is the first index value, nB is the pre-configured paging parameter, _T1 is the discontinuous transmission period, _T2 is the fixed activation period of the discontinuous transmission period, and T is the user The actual paging cycle of the device, F(*) means to take an integer greater than, less than or closest to the specified expression *, max(*, *) means to take the larger value of the two numbers. The usual value range of nB is {4T, 2T, T, T/2, T/4, T/8, T/16, T/32}. This value range is only an example, and the embodiment of the present invention not only Limited to this, the nB may also take other values. The actual paging cycle of the user equipment may be a discontinuous transmission cycle in which the user equipment works in a discontinuous transmission mode.

Step S6, the base station according to the equipment identifier of the user equipment, the actual paging cycle of the user equipment, the pre-configured paging parameters, the discontinuous transmission cycle and the fixed activation period of the discontinuous transmission cycle , using the following eighth formula to calculate the second index value:

i_s=floor(UE_ID/N)mod Ns

Wherein, N=min(T, nB), i_s is the second index value, UE_ID is the device identifier of the user equipment, T is the actual paging cycle of the user equipment, and floor(*) means taking less than or Equal to the largest integer of the specified expression *, mod means modulo operation, min(*, *) means take the smaller value of the two numbers;

Step S7, the base station acquires the subframe number corresponding to the first index value and the second index value according to the correspondence relationship between the first index value, the second index value and the subframe number.

Specifically, the base station pre-stores the correspondence between the first index value, the second index value, and the subframe number. What needs to be explained here is that in the embodiment of the present invention, all paging messages sent by the base station in a paging cycle are controlled to be sent within a fixed active period shorter than the discontinuous sending cycle of the paging cycle, so that the The base station needs to send paging messages on more subframes in one radio frame, therefore, the correspondence between the first index value, the second index value and the subframe number described in this embodiment is different from that in the prior art According to the corresponding relationship, more subframe numbers can be established in the corresponding relationship list according to actual needs. For example: the subframe numbers in the subframe configuration table in the prior art can be extended from the original 0, 4, 5 and 9 to 0, 4, 5, 9, 6, 7, 8 and 2.

Step 203, the base station sends the paging message in the subframe corresponding to the subframe number in the radio frame corresponding to the frame number.

What needs to be added here is: before or at the same time as sending the paging message, the base station broadcasts to all user equipments within the tracking area of the base station or sends a paging message carrying the discontinuous transmission period parameter and the preconfigured Indication information of paging parameters, so that each user equipment determines its own monitoring position according to the discontinuous transmission period parameter and the pre-configured paging parameter, and monitors its own paging message at the determined monitoring position.

Or, after sending the paging message to the user equipment or at the same time, the base station sends indication information carrying the subframe number and frame number for sending the paging message to the user equipment, so that the user equipment Monitoring the paging message on the subframe corresponding to the subframe number in the radio frame corresponding to the frame number.

Or, before or at the same time when sending the paging message, the base station broadcasts to all user equipments in the tracking area of the base station or sends fixed activation period information carrying a discontinuous sending period through dedicated signaling, and is used to instruct the user equipment to keep a distance from The subframe within the fixed active period of the preceding or subsequent discontinuous transmission cycle that is closest to the monitoring position determined by the user equipment itself is used as the indication information of the monitoring position, so that the user equipment can monitor the monitoring distance from the monitoring position determined by the user equipment according to the monitoring indication information. The paging message on the subframe within the active period of the previous or subsequent discontinuous transmission period that is closest. Wherein, the listening position determined by the user equipment itself is determined by the user equipment by using the PF and PO position determination rules in the prior art. For details, refer to the background technology, which will not be repeated here. Of course, in practical applications, monitoring the paging message on the subframe in the active period of the previous or subsequent discontinuous transmission cycle closest to the monitoring position determined by itself can also be used as a protocol agreement of the user equipment. In this way, the base station does not need to send the above indication information to the user equipment, and the user equipment directly listens to the subframe in the active period of the preceding or following discontinuous transmission period closest to the monitoring position determined by itself according to the agreement. call message.

In this embodiment, the base station only sends paging messages during the fixed active period of the discontinuous transmission period, and the base station is in a dormant state during the fixed sleep period of the discontinuous transmission period. In this way, the base station needs to control the sent paging messages to be sent within the fixed activation period of the discontinuous transmission period, so that the time resources in the transmission period can be fully utilized, and the paging messages in the prior art that only use the paging period are avoided. The waste of time resources caused by a limited number of specific subframes; in addition, the base station has a sleep period during the fixed sleep period of the discontinuous transmission period, which also reduces the energy consumption of the base station.

As shown in FIG. 6 , it is a schematic flowchart of the paging method provided by Embodiment 3 of the present invention. As shown in Figure 6, the method described in the third embodiment includes:

Step 301, the base station sends a paging message to the user equipment during the fixed activation period and the mandatory activation period of the discontinuous transmission cycle.

Specifically, the base station controls the paging message to be sent to be sent during the fixed activation period and the mandatory activation period of the discontinuous transmission period. The base station can determine the sending location for sending the paging message according to a rule. According to the actual setting of the fixed activation period and the mandatory activation period, the rule uses a mapping rule to map the sending position determined by the base station using the prior art to the corresponding position in the fixed activation period and the mandatory activation period. The mapping rules are set manually.

The mandatory activation period can also be controlled and set by the base station according to needs, that is, when necessary, the downlink transceiver is forcibly turned on to send paging messages to the user equipment during the fixed sleep period of the discontinuous transmission period. The base station can determine the sending position by adopting the determination rules of the subframe number and the frame number of the radio frame in the prior art, and if the sending position is within the fixed activation period of the discontinuous sending cycle, the sending position will be sent at the sending position For a paging message, if the sending location is within a fixed sleep period of a non-continuous sending period, the base station forcibly turns on the downlink transceiver to send the paging message at the sending location.

Step 302, the base station sends monitoring instruction information to the user equipment, so that the user equipment determines a monitoring location according to the monitoring instruction information, and monitors the paging message at the monitoring location.

Wherein, the monitoring indication information is monitoring indication information carrying discontinuous transmission period parameters and preconfigured paging parameters, so that the user equipment determines a monitoring position according to the discontinuous transmission period parameters and preconfigured paging parameters, and listening to the paging message at the listening position. Wherein, the discontinuous transmission period parameters include: a discontinuous transmission period, a fixed activation period of the discontinuous transmission period, and a mandatory activation period of the discontinuous transmission period. The user equipment may determine the listening position for listening to the paging message according to a rule. This rule is the same as the rule for the base station to determine the sending location of the paging message, that is, according to the fixed activation period and the mandatory activation period of the base station, the sending location determined by the user equipment using the prior art is mapped to corresponding positions in the fixed activation period and the mandatory activation period. The mapping rules are set manually.

Alternatively, the monitoring indication information is monitoring indication information carrying a sending location for sending the paging message, so that the user equipment directly determines the sending location as the listening location, and listens to the paging message at the listening location. the paging message. Wherein, the sending location is the frame number of the radio frame to which the subframe used by the base station to send the paging message belongs and/or the subframe number of the subframe.

Alternatively, the monitoring indication information is the monitoring indication information that carries the activation period information of the discontinuous transmission period and is used to instruct the user equipment to use the specified subframe as the monitoring position, so as to instruct the user equipment to monitor the specified subframe. paging message. Wherein, the activation period information of the discontinuous transmission period includes: a fixed activation period and a mandatory activation period of the discontinuous transmission period. The specified subframe is a subframe within the active period of the previous or subsequent discontinuous transmission period closest to the listening position determined by the user equipment itself; or the specified subframe may also be a The subframe with the same subframe number as the listening position determined by the user equipment itself in the active period of the previous or subsequent discontinuous transmission period of the determined listening position closest; or the specified subframe may also be a distance from the The subframes within the active period of the previous or subsequent discontinuous transmission period in which the monitoring position determined by the user equipment itself is closest is separated from the subframe number of the monitoring position determined by the user equipment itself by a predetermined number of subframes.

Wherein, the self-monitoring position of the user equipment is determined by the user equipment by using the PF and PO position determination rules in the prior art. For details, see the background technology, which will not be repeated here. Certainly, in practical application, monitor the paging message on the subframe within the activation period of the previous or subsequent discontinuous transmission cycle closest to the monitoring position determined by itself, or monitor the monitoring position away from the determined monitoring position of the user equipment itself The paging message on the subframe with the same subframe number as the monitoring position determined by the user equipment itself during the activation period of the latest previous or subsequent discontinuous transmission period; or monitor the monitoring distance from the monitoring position determined by the user equipment itself The paging message on the subframe that is separated from the subframe number of the listening position determined by the user equipment itself in the activation period of the previous or subsequent discontinuous transmission period with the closest position by the agreed number of subframes may also be used as the user equipment agreement agreement. In this way, the base station does not need to send the above indication information to the user equipment, and the user equipment directly listens to the subframe in the active period of the preceding or following discontinuous transmission period closest to the monitoring position determined by itself according to the agreement. call message.

In this embodiment, the base station only sends paging messages during the fixed activation period and the mandatory activation period of the discontinuous transmission period, and the base station is in a dormant state during the fixed activation period of the discontinuous transmission period except the mandatory activation period. In this way, the base station needs to control the sent paging messages to be sent during the fixed activation period and the mandatory activation period of the discontinuous transmission period, so that the time resources in the transmission period can be fully utilized, and the paging period in the prior art is avoided. The waste of time resources caused by a limited number of specific subframes in the wireless frame; in addition, the base station has a sleep period during the fixed sleep period of the discontinuous transmission period, which also reduces the energy consumption of the base station.

As shown in FIG. 7 , it is a schematic flowchart of a paging method provided by Embodiment 4 of the present invention. As shown in Figure 7, the method described in Embodiment 4 includes:

Step 401, the base station sends a paging message to the user equipment within the sending period indicated by the sending indication information of the preset pattern.

Wherein, the preset pattern includes at least one sending indication information within a preset period. Specifically, the preset pattern may be characterized as a string of character strings or a symbol string composed of other identification symbols. For example, character 1 represents sending instruction information, and character 0 is dormancy instruction information. The preset pattern may be characterized as: a character string of 0100001000. Assuming that the preset period is 10ms, the time period identified by each character in the preset pattern is 1ms. The position marked as 1 is the sending instruction information, indicating that the base station can send the paging message within the sending period indicated by the sending instruction information, that is, within 1 ms. The position marked as 0 is the dormancy indication information, indicating that the base station is in a dormancy state during the dormancy period indicated by the dormancy indication information.

Wherein, the sending indication information is radio frame level time period indication information or subframe level time period indication information. If the transmission indication information is radio frame level period indication information, the base station determines the subframe used to send the paging message in the radio frame indicated by the radio frame level period indication information, and in the subframe Send the paging message. If the sending indication information is subframe-level period indication information, the base station sends a paging message within the indicated subframe.

It can be further expanded here that: the preset pattern described in this embodiment is a pattern in the time domain. In essence, the preset pattern can also be a control channel or data channel pattern in the frequency domain. The base station can send signaling or data on the control signal or data channel specified in the pattern according to the control channel pattern or the data channel pattern.

Step 402, the base station sends monitoring instruction information carrying the sending location where the user sends the paging message to the user equipment, so that the user equipment monitors the paging message at the sending location.

Wherein, the sending location is the frame number of the radio frame to which the subframe used by the base station to send the paging message belongs and/or the subframe number of the subframe.

In this embodiment, the base station only sends paging messages during the sending period indicated by the sending instruction information of the preset pattern, and the base station is in a dormant state during the preset period of the preset pattern except for the sending period indicated by the sending instruction information. In this way, the base station needs to control the sending of the paging messages to be sent within the sending period indicated by the sending instruction information of the preset pattern, so that the time resources in the sending period can be fully utilized, and the wireless network that only uses the paging cycle in the prior art can be avoided. The waste of time resources caused by the limited number of specific subframes in the frame; in addition, the base station has a sleep period during the fixed sleep period of the discontinuous transmission period, which also reduces the energy consumption of the base station.

As shown in FIG. 8 , it is a schematic flowchart of the paging method provided by Embodiment 5 of the present invention. As shown in Figure 8, the method described in Embodiment 5 includes:

Step 501, the base station sends a paging message to the user equipment during the active period of the discontinuous transmission period or within the transmission period indicated by the transmission indication information of the preset pattern.

Wherein, there is at least one sending instruction information of the preset pattern, and each sending instruction information corresponds to a preset sending period within a preset period. The base station sends the paging message to the user equipment during the fixed activation period of the discontinuous sending cycle, and reference may be made to the content described in the second embodiment above, and details are not described here again. The base station sends the paging message to the user equipment during the fixed activation period and the mandatory activation period of the discontinuous transmission period, and reference may be made to the content described in the third embodiment above, which will not be described in detail here. The base station sends the paging message to the user equipment within the sending period indicated by the sending instruction information of the preset pattern, and reference may be made to the content described in the fourth embodiment above, and details will not be described here.

Step 502: Send monitoring instruction information to the user equipment, so that the user equipment determines a monitoring location according to the monitoring instruction information, and monitors a paging message at the monitoring location.

Specifically, reference may be made to the relevant content described in Embodiment 1, 2, 3 or 4 above.

Step 503: Start the uplink timer, so as to receive the uplink data sent by the user equipment between the start time of the uplink timer and the set time of the uplink timer.

In this embodiment, after the base station sends the paging message, in order to make the subsequent interaction between the base station and the user equipment effective immediately, the above step 503 is added, that is, the base station is required to turn on the uplink transceiver so that the base station can receive the paging message in time. After the user equipment listens to its own paging message, the uplink data sent to the base station, such as scheduling request or random access scrambling code, etc., prevents the base station from receiving it during the activation period of the next discontinuous transmission cycle Uplink data sent by the user equipment.

Further, in order to allow the base station and the user equipment to interact in a timely manner, after the above step 503, it also includes: if the uplink data sent by the user equipment is received, start a downlink timer, so that the downlink timer can be started from the start time of the downlink timer to the Returning response information corresponding to the uplink data to the user equipment within the set time of the downlink timer.

Still further, before the above step 501, it also includes: sending to the user equipment a message carrying the base station identifier of at least one base station operating in the discontinuous transmission mode, so that the user equipment can avoid camping in the message The base station corresponding to the carried base station identifier monitors the paging message.

What needs to be explained here is that in a heterogeneous network, a macro base station is covered by multiple access nodes, and these nodes can be small base stations Pico, indoor base stations Femto, low mobility base stations LoMo, local wireless access points AP, Low power transmitting node (Low Power Node, LPN), etc. None of these access nodes has the function of delivering paging messages. Only the macro base station has the function of sending paging messages. The user equipment needs to choose to camp on the macro base station (that is, the first base station in this embodiment) capable of delivering paging messages, and avoid camping on the access node covered by the macro base station. Therefore, the above steps are added before step 501 in this embodiment. Specifically, the macro base station sends information carrying identifiers of all access nodes under the macro base station to the user equipment through broadcast or dedicated signaling. After receiving the information, the user equipment directly chooses to camp under the macro base station, and avoids camping under the access node corresponding to the identifier, and the macro base station sends a paging message to the user equipment, or the macro base station Sending a paging message to user equipment under the access node instead of the access node.

As shown in FIG. 9 , it is a schematic flowchart of the paging method provided by Embodiment 6 of the present invention. The sixth embodiment describes the paging method from the terminal side. Specifically, as shown in Figure 9, the method described in Embodiment 6 includes:

Step 601, the user equipment receives monitoring indication information sent by the base station.

Step 602, the user equipment determines an interception location according to the interception instruction information.

Step S2', according to the initial value of the frame number, the actual paging period, the discontinuous transmission period and the fixed activation period of the discontinuous transmission period, using a preset mapping rule to convert the initial value of the frame number to Mapped to the frame number corresponding to the fixed active period of the discontinuous transmission cycle, the frame number is the frame number of the radio frame to which the subframe monitoring the paging message belongs.

Wherein, the preset mapping rule is specifically the following second formula:

Alternatively, the preset mapping rule is specifically the following fourth formula:

SFN'=floor(SFN/T ₂ )×T ₂ +F((SFN mod T)×(T1/T)×(1/floor(T/T ₂ )));

Alternatively, the preset mapping rule is specifically the following fifth formula:

SFN'mod T ₂ =floor((T ₁ /N')×(UE_ID mod N'))

Wherein, N'=T or T ₂ .

Further, if the discontinuous transmission period parameter also includes: the start time offset value of the fixed activation period of the discontinuous transmission period, it also includes:

Step S3', according to the start time offset value of the fixed activation period of the discontinuous transmission period, modify the frame number of the radio frame to which the subframe monitoring the paging message belongs. Specifically, according to the start time offset value of the fixed activation period of the discontinuous transmission cycle, the frame number of the wireless frame to which the subframe used to send the paging message belongs is corrected by using the following ninth formula:

SFN”=floor((SFN’×10+P0+dtxStartOffset)/10)

Wherein, SFN" is the modified frame number of the wireless frame to which the subframe of the paging monitoring message belongs, SFN' is the frame number of the wireless frame to which the subframe of the paging monitoring message belongs, and P0 is the frame number of the paging monitoring message The subframe number of the subframe, dtxStartOffset is the start time offset value of the activation period of the discontinuous transmission period.

Finally, the user equipment determines, according to the discontinuous transmission period parameter, the pre-configured paging parameter, the device identifier and the actual paging period, the frame of the wireless frame to which the subframe for monitoring the paging message belongs No.

Specifically, if the discontinuous transmission period parameters include: the discontinuous transmission period and the fixed activation period of the discontinuous transmission period, wherein the activation period is the fixed activation period of the discontinuous transmission period; then according to the discontinuous transmission period Send cycle parameters, pre-configured paging parameters, the device identifier and the actual paging cycle, determine the subframe number of the subframe that monitors the paging message, the specific process is as follows:

Step S4', according to the actual paging cycle, the pre-configured paging parameters, the discontinuous transmission cycle and the fixed activation period of the discontinuous transmission cycle, using the following sixth formula to calculate the first index value:

Step S6', according to the corresponding relationship between the first index value, the second index value and the subframe number, obtain the subframe number corresponding to the first index value and the second index value.

Specifically, the base station pre-stores the correspondence between the first index value, the second index value, and the subframe number. What needs to be explained here is that in the embodiment of the present invention, all paging messages sent by the base station in a paging cycle are controlled to be sent during the active period of the discontinuous sending cycle, so that the base station needs to send all paging messages in a radio frame Paging messages are sent on more subframes. Therefore, the correspondence between the index value and the subframe number described in this embodiment is different from that in the prior art, and more subframe numbers can be established according to actual needs. in the list of correspondences.

If the discontinuous transmission period parameter includes: a discontinuous transmission period, a fixed activation period of the discontinuous transmission period, and a mandatory activation period of the discontinuous transmission period. The user equipment may determine the listening position for listening to the paging message according to a rule.
