Description

Method, device and system for cell paging

technical field

The present invention relates to communication technology, in particular to a cell paging method, device and system.

Background technique

In the prior art, a universal mobile telecommunications system (Universal Mobile Telecommunications System, UMTS for short) bandwidth is fixed, and the standard bandwidth is 5 MHz.

In order to use the bandwidth of different frequency bands. With the continuous development of technology, Scalable Universal Mobile Telecommunications System (Scalable Universal Mobile Telecommunications System, referred to as: S-UMTS), that is, narrowband UMTS, has been introduced. The bandwidth of the S-UMTS is lower than the standard 5MHz. Specifically, it can be scaled according to different The factor N scales the standard bandwidth, and the bandwidth of the S-UMTS can be 1/N of the standard bandwidth, such as 1/2, 1/4, and so on. At the same time, in order to ensure that S-UMTS and UMTS have the same power spectral density, after scaling the S-UMTS bandwidth, it is also necessary to extend the S-UMTS radio frame extension time slot. In this way, for a radio frame with a duration of 10ms, when transmitted in S-UMTS, the radio frame becomes N×10ms. For example, a radio frame takes 10ms to transmit 300bits. In an S-UMTS with a scaling factor N of 2, the radio frame transmission takes 20 ms to transmit 300 bits. For UMTS, paging interval time=n×radio frame length×discontinuous reception cycle length (DRXCycleLength), where DRXCycleLength is broadcast by the UMTS system to each user in the cell, n is an integer, and its value can be, 0 ,1,….

However, it can be seen from the expression of the paging interval time above that the change of the radio frame length will affect the paging interval time, because in order to maintain the same power spectral density in S-UMTS, the S-UMTS radio frame is extended by Therefore, according to the existing expression of the paging interval time, it can be known that for an S-UMTS with a scaling factor of N, when the original radio frame length is 10ms, the corresponding S-UMTS radio frame length is N×10ms. Therefore, according to the existing method for obtaining the paging interval time, the paging interval time in S-UMTS will be extended, and since the radio frame length of S-UMTS is N×10ms, in a radio frame of S-UMTS When setting the paging position in the existing technology, it needs to be set within the entire N×10ms, which will also cause the paging cycle of the equipment related to paging in the system and the user equipment that needs to detect paging to be extended, which will further cause The power consumption of the user equipment increases.

detailed description

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 making creative efforts belong to the protection scope of the present invention.

In the prior art, in addition to the paging delay caused by the paging interval of the Scalable Universal Mobile Telecommunications System (Scalable Universal Mobile Telecommunications System, referred to as: S-UMTS), it is also mentioned above that S-UMTS requires The paging position is set within ×10ms, that is, the sending and detection of the paging indication will consume N*10ms, so the paging cycle is lengthened. In order to reduce the lengthened time delay, the present invention sets the paging position to the first 10ms (the first 10ms) of a radio frame. If the paging position method in the prior art is used directly, the following problems arise.

According to a specific example, the paging position in the prior art will be described below. Figure 1 is a schematic diagram of a wireless frame provided by the Universal Mobile Telecommunications System (UMTS for short). Referring to Figure 1, it should be noted that in the network The network element equipment of the system selects the paging opportunity (that is, the second paging opportunity of the second system below), and performs paging at the position q of the radio frame of the paging opportunity, and the position q is the specific number of the 300 bits, that is, From b ₀ to b ₂₉₉ in 1, the corresponding UE reads the Paging Indicator Channel (PagingIndicatorChannel: PICH for short) information at the same paging timing and position in the same way, and the bit at this position is set to 1 to indicate paging information. For an existing UMTS with a bandwidth of 5 MHz, the PICH adopts a quadrature phase shift keying (Quadrature Phase Shift Keying, referred to as: QPSK) modulation method, the spreading factor (Spreading Factor, referred to as: SF) is 256, and the wireless frame carries 300 bits in 10 ms. Further, the paging position is _bc×q , where c is the number of repetitions corresponding to the number Np of the first paging indication. Referring to Table 1, Np has the following relationship with the number of repetitions c:

Table I

Np=18 Np=36 Np=72 Np=144 repeat value c 16 8 4 2

For example, Np=18, repeat 16 position 1 from c*q, that is, b _16q =b _16q+1 =b _16q + _{2. . .} =b _16q+15 =1. Np=36, repeat 8 positions from c*q to 1. Np=72, repeat 4 positions from c*q to 1. Np=144, repeat 2 position 1 from c*q. It can be seen that among the 300 bits within the first 10 ms of the wireless frame of the first system, 18*16=36*8=72*4=2*144=288 bits are occupied, and the remaining 12 bits are reserved by the system and will not be used temporarily. However, when the above technical solution is applied to the Scalable Universal Mobile Telecommunications System (Scalable Universal Mobile Telecommunications System, referred to as: S-UMTS), in order to maintain the same power spectral density as the original UMTS in S-UMTS, the S-UMTS radio The frame expands the time slot, a wireless frame N*10ms is 300bits, and the first 10ms is 300/Nbits. Therefore, when the above technical solution is adopted, it is impossible to ensure that the paging position is set in the 300 bits carried in the first 10 ms of the radio frame. Then, the entire N*10ms radio frame should be used to set the paging position, thus resulting in an increase of the entire S-UMTS paging delay and power consumption. The following describes how the present invention solves the above two technical problems through various embodiments provided by the present invention.

Fig. 2 is a schematic flowchart of a cell paging method provided by Embodiment 1 of the present invention. The execution subject is a network element device in a scalable universal mobile telecommunications system (Scalable Universal Mobile Telecommunications System, referred to as: S-UMTS), such as a base station, as shown in Fig. 2 As shown, the method of cell paging includes the following contents:

100. The network element device determines the first paging opportunity, so that the interval between the first paging opportunity calculated by the first system and the second paging opportunity calculated by the second system is consistent, wherein the radio frame of the first system is N×10ms, The radio frame of the second system is 10 ms, and N is a positive integer.

Specifically, the first system is S-UMTS, and the second system is UMTS. The wireless frame length of the UMTS system is 10ms, the frame length of the S-UMTS system is N*10ms, and the time slot (slot) rate is reduced by N times compared with UMTS.

It should be noted that the above "consistent" means the same order of magnitude, that is, falls within the interval: [2 ^t -2 ^t+1 )*one wireless frame length, t=1, 2, 3.... For example, the UMTS paging interval is 320ms, which falls in the interval [2 ⁵ -2 ⁶ )*10ms, where t=5; if the S-UMTS paging interval is 340ms, the interval is also [2 ⁴ -2 ⁵ )* 20=[2 ^5- 2 ⁶ ]*10ms, this article considers them to be consistent.

101. The network element device determines the position of the first paging indication, so that the position of the first paging indication is within the first 10 ms of the radio frame of the first system, so as to offset the extension of the paging cycle due to the time slot extension.

102. The network element device sends a radio frame to a user equipment (User Equipment, UE for short) to perform paging.

In the cell paging method provided in this embodiment, the network element equipment determines the first paging opportunity, so that the interval between the first paging opportunity calculated by the first system and the second paging opportunity calculated by the second system are consistent, and then the second paging opportunity is determined. The position of a paging indication, so that the position of the first paging indication is within the first 10ms of the radio frame of the first system, offsetting the prolongation of the paging interval time caused by the time slot expansion, and avoiding setting in the entire radio frame length The paging period caused by the paging position is prolonged. Furthermore, the network element equipment sends the radio frame containing the paging indication to the UE for paging, which reduces the period for the UE to detect paging opportunities and further reduces the UE's power consumption.

Further, for 100 in Embodiment 1, a possible implementation is as follows:

The first paging opportunity is determined by the following formula:

The first paging opportunity=f ₁ (IMSI)+n×S-UMTS discontinuous reception cycle length DRXCycleLength;

Wherein, IMSI is an International Mobile Subscriber Identity (InternationalMobileSubscriberIdentity, referred to as: IMSI), f ₁ (IMSI) is a function whose input parameter is IMSI and the output value is less than the DRXCycleLength of the first system, n is an integer, and the value range is from 0 to Maximum frame number for Scalable Universal Mobile Telecommunications System S-UMTS.

Specifically, f ₁ (IMSI)=(IMSI) mod (DRXCycleLength of S-UMTS). It should be noted that, in this embodiment, the DRXCycleLength of S-UMTS is broadcasted by the system in the cell, and each UE can received.

It should be noted that the paging occasion interval length=paging occasion interval*radio frame length.

Further, since the radio frame of S-UMTS is extended, after the first paging occasion is determined, the interval length of the first paging occasion is also extended. In order to reduce the time interval of the first paging occasion, the following two A possible implementation manner further processes the first paging occasion:

First, set the DRXCycleLength of S-UMTS equal to the DRXCycleLength of UMTS, then after determining the first paging opportunity, it also includes:

method one:

Divide the first paging occasion by N and round up.

Specifically, for example, the DRXCycleLength(k) of the S-UMTS is set equal to the DRXCycleLength(K) of the UMTS, where k=6,7,8,9.

Or, method two:

The DRXCycleLength of the S-UMTS is one-Nth of the DRXCycleLength of the UMTS.

Specifically, for example, DRXCycleLength (k) of S-UMTS and DRXCycleLength (K) of UMTS, where k=K-log ₂ N, for example, when N=2, k=5, 6, 7, 8; N=4 When, k=4, 5, 6, 7.

Further, on the basis of the above-mentioned first embodiment and various possible implementations, for 101 in the first embodiment, a possible implementation is as follows:

The position of the first paging indication is determined by the following formula:

q=(f ₄ (IMSI)+f ₂ (SFN))modf ₃ (Np);

Among them, q is the position of the first paging indication, SFN is the system frame number of S-UMTS, Np is the number of the first paging indication of each radio frame, f ₄ (IMSI) is the function of the input parameter is IMSI, f ₄ (IMSI) is used to randomly assign user equipment UE to different paging groups according to IMSI, f ₂ (SFN) is a function whose input parameter is SFN, f ₃ (Np) is a function whose input parameter is Np, f ₂ (SFN) and f ₃ (Np) are used to evenly set the position of UE paging.

Specifically, Np may be delivered to each UE through a system broadcast of the cell. f ₃ (Np) can be rounded after Np/N, where N=2, 4, . . .

Further, on the basis of the above-mentioned first embodiment and each possible implementation manner, before 100 in the first embodiment, it also includes:

According to the size of N, the spreading factor SF is reduced to offset the prolongation of the paging cycle due to time slot expansion.

Specifically, when N is set to 2, the SF is set to 128; or, when N is set to 4, the SF is set to 64. When SF is set to 128, one radio frame transmits 600 bits. When SF is set to 64, one wireless frame transmits 1200bit. For S-UMTS, a radio frame is N×10ms, and when the SF is 128, the number of bits occupied by the first 10ms of the 1/N frame of the radio frame transmission is 600/Nbits. When the SF is 64, the number of bits occupied by the first 10 ms of the 1/N frame of wireless frame transmission is 1200/Nbits. For the existing technology, the S-UMTS radio frame has extended time slots, a radio frame N*10ms is 300bits, and the first 10ms is 300/Nbits, which leads to the need to use the entire N*10ms radio frame to set paging in the prior art Location. Compared with the prior art, in this embodiment, on the basis that the network element equipment determines the first paging occasion so that the interval between the first paging occasion calculated by S-UMTS and the second paging occasion calculated by UMTS are consistent, That is, when the first 10 ms of S-UMTS is 300 bits, according to the size of N, reduce the spreading factor SF to ensure that the position of the first paging indicator is within the first 10 ms of the radio frame of the first system, that is, in the radio frame In the 300bits occupied by 10ms, when N=2, set SF to 128. When N=4, set SF to 64. And it can be deduced in turn. In this way, when the UE receives the radio frame, it only needs to detect the first 10 ms of the 1/N frame to obtain the paging indication.

Optionally, on the basis of the foregoing Embodiment 1 and various possible implementation manners, before 100 in Embodiment 1, further includes:

Keep the spreading factor SF of the paging indicator channel PICH unchanged, and change the modulation method from the quadrature phase shift keying signal QPSK to the quaternary quadrature amplitude modulation 16QAM or the octal quadrature amplitude modulation 64QAM to offset the time slot expansion for Extension of the paging cycle.

Preferably, on the basis of the above-mentioned first embodiment and each possible implementation manner, before 100 in the first embodiment, it further includes:

Keep Np unchanged, and modify the number of repetitions corresponding to each Np; or, keep the number of repetitions corresponding to Np unchanged, and modify Np.

Specifically, modifying Np or modifying the number of repetitions corresponding to Np will be described below through two specific embodiments.

Embodiment two

The network only sends the paging indication in the first 10ms of the radio frame, and the UE only detects the first 10ms of each radio frame. In turn, the data (300bits/N) carried by the first radio frame of the system, when N= When 2, the carried data is 150 bits; when N=4, the carried data is 75 bits. For example, referring to Table 2, when N=2, in order to ensure that Np can take a value of 18, 36, 72 or 144, it is necessary to set the number of repetitions corresponding to Np to be 8, 4, 2 or 1. In this way, the product of Np and the corresponding number of repetitions requires a total of data bits within 150 bits. That is, if Np is 18, adjust the number of repetitions corresponding to Np to 8; or, if Np is 36, adjust the number of repetitions corresponding to Np to 4; or, if Np is 72, adjust the number of repetitions corresponding to Np to 2 ; Or, if Np is 144, adjust the number of repetitions corresponding to Np to 1.

Table II

Np=18 Np=36 Np=72 Np=144 repeat value c 8 4 2 1

Embodiment three

In the case that the value of the number of repetitions remains unchanged, modify Np. Taking N=2 as an example, when N=2, the carried data is 150 bits. Referring to Table 3, the values of the number of repetitions are: 16, 8, 4 or 2, respectively. At this time, set Np to 9 or 18 or 36 or 72. To ensure that the product of Np and the corresponding number of repetitions requires a total of data bits within 150 bits. Similarly, when N=4, the carried data is 75 bits. Then set Np to 4 or 8 or 16 or 32 on the premise that the number of repetitions c remains unchanged. To ensure that the product of Np and the corresponding number of repetitions is within 75 bits.

Table three

Np=9 Np=18 Np=36 Np=72 repeat value c 16 8 4 2

Fig. 3 is a schematic flowchart of a cell paging method provided in Embodiment 4 of the present invention, where the execution subject is the user equipment UE. The method is consistent with the network element equipment, as shown in Figure 3, the cell paging method includes the following content:

200. A user equipment UE detects a radio frame sent by a network element device at a first paging occasion.

Wherein, the interval between the first paging opportunity calculated by the first system and the second paging opportunity calculated by the second system is consistent, the radio frame of the first system is N×10ms, the radio frame of the second system is 10ms, and N is a positive integer ;

Specifically, the first system is S-UMTS, and the second system is UMTS. The frame length of the UMTS system is 10ms, the frame length of the S-UMTS system is N*10ms, and the slot rate is N times lower than that of UMTS. The first paging occasion is the paging occasion of the first system, that is, the paging occasion of S-UMTS, and the second paging occasion is the paging occasion of the second system, that is, the paging occasion of UMTS.

It should be noted that the above "consistent" means the same order of magnitude, that is, falls within the interval: [2 ^t -2 ^t+1 )*one wireless frame length, t=1, 2, 3.... For example, the UMTS paging interval is 320ms, which falls in the interval [2 ⁵ -2 ⁶ )*10ms, where t=5; if the S-UMTS paging interval is 340ms, the interval is also [2 ⁴ -2 ⁵ )* 20=[2 ^5- 2 ⁶ ]*10ms, this article considers them to be consistent.

The UE has the radio capability to support the S-UMTS system.

201. The UE detects a first paging indication at a corresponding position within the first 10 ms of a radio frame of the first system.

202. If the UE detects the first paging indication, it reads a paging message on a related channel.

Specifically, if the UE detects a paging indication at the corresponding location, the subsequent process is the same as the existing process, that is, to read the paging message on the secondary common physical control channel S-CCPCH (Secondary Common Control Physical Channel).

In the cell paging method provided in this embodiment, first, the UE detects the radio frame sent by the network element device at the first paging occasion, wherein the first paging occasion calculated by the first system and the second paging occasion calculated by the second system The intervals are the same; within the first 10ms of the radio frame of the first system, the position of the first paging indication is detected again, and if the paging indication is detected, the paging message is subsequently read. Make the time spent by the S-UMTS UE and the UMTS UE to detect the paging indication the same, which reduces the prolongation of the period for the UE to detect the paging occasion due to the length of the radio frame in the S-UMTS system, and further reduces the power consumption of the UE. electricity.

Further, for 200 in Embodiment 4, a possible implementation is as follows:

The first paging opportunity is determined by the following formula:

The first paging opportunity=f ₁ (IMSI)+n×S-UMTS discontinuous reception cycle length DRXCycleLength;

Wherein, IMSI is the International Mobile Subscriber Identity code, f ₁ (IMSI) is a function whose input parameter is IMSI and the output value is less than the DRXCycleLength of the first system, n is an integer, and the value range is from 0 to the scalable universal mobile communication system S - Maximum frame number of UMTS.

Specifically, it is described in the corresponding implementation manner with the network element device as the execution subject, and will not be repeated here.

Paging opportunity interval length = paging opportunity interval * wireless frame length.

Further, since the radio frame of S-UMTS is extended, after the first paging occasion is determined, the interval length of the first paging occasion is also extended. In order to reduce the time interval of the first paging occasion, the following two A possible implementation manner further processes the first paging occasion:

First, set the DRXCycleLength of S-UMTS equal to the DRXCycleLength of UMTS, then at the first paging opportunity, before receiving the wireless frame sent by the network element device, it also includes:

method one:

dividing the first paging occasion by N and rounding;

Or, method two:

The DRXCycleLength of the S-UMTS is one-Nth of the DRXCycleLength of the UMTS.

Further, on the basis of the foregoing fourth embodiment and various possible implementation manners, for 201 in the fourth embodiment, a possible implementation manner is as follows:

The first paging indication of the corresponding position is detected by the following formula:

q=(f ₄ (IMSI)+f ₂ (SFN))modf ₃ (Np);

Among them, q is the position of the first paging indication, SFN is the system frame number of S-UMTS, Np is the number of the first paging indication of each radio frame, f ₄ (IMSI) is the function of the input parameter is IMSI, f ₄ (IMSI) is used to randomly assign user equipment UE to different paging groups according to IMSI, f ₂ (SFN) is a function whose input parameter is SFN, f ₃ (Np) is a function whose input parameter is Np, f ₂ (SFN) and f ₃ (Np) are used to evenly set the position of UE paging.

After determining q, it is evaluated whether there is a paging indication along with receiving the signal of c-bit data of repetition value. If there is a paging instruction, go to the S-CCPCH channel to read the paging message.

c is determined by the system, and the UE maintains the same algorithm as the network, that is, the Np adjustment or c adjustment is the same as the network, that is, the above-mentioned example 2 and example 3. Once the system selects a specific method, both the network and the UE use the same Np and c.

Further, before 200 in Embodiment 4, it also includes:

According to the size of N, the spreading factor SF is reduced to offset the prolongation of the paging cycle due to time slot expansion.

Specifically, when N is set to 2, the SF is set to 128; or, when N is set to 4, the SF is set to 64.

Optionally, on the basis of the foregoing fourth embodiment and various possible implementation manners, before 200 in the fourth embodiment, further includes:

Keep the spreading factor SF of the paging indicator channel PICH unchanged, and change the modulation method from the quadrature phase shift keying signal QPSK to the quaternary quadrature amplitude modulation 16QAM or the octal quadrature amplitude modulation 64QAM to offset the time slot expansion for Extension of the paging cycle. If S-UMTS wants to change the SF of PICH, the network and UE adopt the same method. That is the method in Example 1.

Preferably, on the basis of the foregoing fourth embodiment and various possible implementation manners, before 200 in the fourth embodiment, it further includes:

Keep Np unchanged, and modify the number of repetitions corresponding to each Np; or, keep the number of repetitions corresponding to Np unchanged, and modify Np.

Specifically, referring to Embodiment 2, it can be known that when Np is kept unchanged and the number of repetitions corresponding to each Np is modified, it may specifically include: Np is 18, and the number of repetitions corresponding to Np is adjusted to 8; or, Np is 36, then adjust the number of repetitions corresponding to Np to 4; or, if Np is 72, adjust the number of repetitions corresponding to Np to 2; or, if Np is 144, adjust the number of repetitions corresponding to Np to 1.

Referring to Embodiment 3, it can be seen that the number of repetitions corresponding to the number of paging indications remains unchanged, and Np is modified, specifically including: N is 2, then Np is set to 9 or 18 or 36 or 72; or, N is 4, then set Np is 4 or 8 or 16 or 32.

FIG. 4 is a schematic diagram of signaling interaction of the cell paging method provided in Embodiment 5 of the present invention. As shown in FIG. 4, the interaction between the network element device and the UE includes the following content:

300. A network element device determines a first paging opportunity and a location of a first paging indication.

Specifically, refer to step 101 and step 102 in Embodiment 1, which will not be repeated here.

301. A network element device sends a radio frame to a user equipment UE on a PICH channel to perform paging.

Specifically, the radio frame includes the first paging indication.

302. The UE detects a first paging indication at a corresponding location at a first paging occasion of a PICH channel.

303. If the paging indication is obtained, the UE reads the paging message through the S-CCPCH channel.

FIG. 5 is a schematic structural diagram of a cell paging device provided by Embodiment 6 of the present invention. As shown in FIG.

The paging occasion determination module 10 is configured to determine a first paging occasion so that the first paging occasion calculated by the first system is at the same interval as the second paging occasion calculated by the second system, wherein the radio frame of the first system is N×10ms, the radio frame of the second system is 10ms, and N is a positive integer.

Specifically, the first system is S-UMTS, and the second system is UMTS.

It should be noted that the above "consistent" means the same order of magnitude, that is, falls within the interval: [2 ^t -2 ^t+1 )*one wireless frame length, t=1, 2, 3.... For example, the UMTS paging interval is 320ms, which falls in the interval [2 ⁵ -2 ⁶ )*10ms, where t=5; if the S-UMTS paging interval is 340ms, the interval is also [2 ⁴ -2 ⁵ )* 20=[2 ^5- 2 ⁶ ]*10ms, this article considers them to be consistent.

The paging indication position determination module 11 is used to determine the position of the first paging indication, so that the position of the first paging indication is within the first 10 ms of the S-UMTS radio frame, so as to offset the extension of the paging cycle due to the time slot extension ;

The sending module 12 is configured to send a radio frame to the user equipment UE for paging.

In the cell paging device provided in this embodiment, the first paging occasion is determined by the paging occasion determining module, so that the interval between the first paging occasion calculated by S-UMTS and the second paging occasion calculated by UMTS are consistent, and the paging indication The position determining module determines the position of the first paging indication, so that the position of the first paging indication is within the first 10 ms of the S-UMTS radio frame, offsetting the prolongation of the paging interval time caused by the time slot expansion, and avoiding the paging interval in the entire The paging period caused by setting the paging position within the radio frame length is extended. Further, the sending module sends the radio frame containing the paging indication to the UE for paging, which reduces the period for the UE to detect the paging opportunity, and further The power consumption of the UE is reduced.

Further, the paging occasion determining module 10 specifically determines the first paging occasion through the following formula:

The first paging opportunity=f ₁ (IMSI)+n×S-UMTS discontinuous reception cycle length DRXCycleLength;

Wherein, IMSI is the International Mobile Subscriber Identity code, f ₁ (IMSI) is a function whose input parameter is IMSI and the output value is less than the DRXCycleLength of the first system, n is an integer, and the value range is from 0 to the scalable universal mobile communication system S - Maximum frame number for UMTS.

Further, since the radio frame of S-UMTS is extended, after the first paging occasion is determined, the first paging occasion is also extended. In order to reduce the time interval of the first paging occasion, the following paging occasion is determined Module 10 can further process the first paging occasion through two possible implementations:

First, the paging opportunity determination module 10 is used to set the DRXCycleLength of S-UMTS to be equal to the DRXCycleLength of UMTS, and after detecting the first paging opportunity, it also includes:

method one:

The paging occasion determination module 10 is also used to divide the first paging occasion by N and round it up;

Or, method two:

The paging opportunity determining module 10 is further configured to set the DRXCycleLength of S-UMTS to one-Nth of the DRXCycleLength of UMTS.
