Description

Processing method of paging resource, paging method, base station and terminal

Technical Field

The present invention relates to the field of communications technologies, and in particular, to a paging resource processing method, a paging method, a base station, and a terminal.

Background

The NB-IoT (Narrow Band Internet of Things over cellular)/enhanced machine-type communication eMTC existing paging mechanism has followed LTE (long term evolution). For example, for NB-IoT, in each Paging cycle (Paging cycle), the NB-IoT determines the Paging occasion, i.e. the location of the Paging frame PF and the Paging occasion PO, by the parameters Paging cycle T, Paging density NB, terminal identity UE _ ID. The paging cycle T and the paging density nB are broadcast by the wireless network, and the terminal identity UE _ ID is calculated from the terminal's IMSI (international mobile subscriber identity), e.g., for nB-IoT, UE _ ID — IMSI mod 4096. In one paging cycle, the NB-IoT terminal listens for paging messages only at one paging occasion. Like LTE, PDCCH for Paging (physical downlink control channel for Paging) in one Paging occasion schedules one Paging message, which can page multiple terminals simultaneously.

For a radio technology (NB-IoT/eMTC) with a Coverage Enhancement Level (CEL), if one Paging message needs to page two terminals at the same time, and the two terminals are at different Coverage levels, a PDCCH for Paging and a PDSCH for Paging (physical downlink shared channel for Paging) of a base station need to consider the terminal with the worst Coverage Level, which is equivalent to forcibly performing redundant repetition (repetition) on the terminal with a good Coverage condition, so that the PDCCH and the PDSCH for Paging occupy more downlink resources, and Paging efficiency is not high. For example, as shown in fig. 1, there are 2 NB-IoT terminals in a cell, UE1 is at coverage enhancement level 0, and UE2 is at coverage enhancement level 2. The IMSIs for UE1 and UE2 differ by 4096, so the calculated UE _ ID is the same. Since T, nB, and UE _ ID are the same for both UEs, the calculated paging location is also the same. Then, if the base station is to page the two UEs simultaneously, the base station needs to repeat according to the coverage enhancement level of the UE2 to ensure that the UE2 can receive the paging message, so that the paging mechanism consumes more system capacity under the same paging traffic.

In the prior art, one solution to this problem is that a base station may send paging messages of different coverage enhancement levels in different time intervals based on a "collision > delay" paging optimization method, and place a paging message of a certain coverage intensity level into the next paging cycle for transmission. As shown in fig. 2, which is a schematic diagram of a paging optimization method of "collision > delay", the paging message of the UE2 is sent with a delay of one cycle, so that the base station does not need to repeat when sending the paging message of the UE1, and downlink resources are saved.

In summary, the disadvantages of the existing paging optimization method are as follows:

1. the delay of the paging message results in an increased paging delay, which degrades the user experience for delay sensitive users.

2. The delayed paging message may collide again with other paging messages of coverage enhancement classes in the next paging cycle and continue to be delayed, and thus, the delay also has uncertainty.

Detailed Description

In order to make the technical problems, technical solutions and advantages of the present invention more apparent, the following detailed description is given with reference to the accompanying drawings and specific embodiments.

As shown in fig. 3, an embodiment of the present invention provides a method for processing paging resources, which is applied to a base station, and includes:

step 31, acquiring the grade number of the coverage enhancement grade supported by the wireless communication system;

step 32, dividing the paging resource in the target paging cycle into a plurality of paging resource areas according to the grade number of the coverage enhancement grade; wherein different coverage enhancement levels correspond to different paging resource zones.

In other words, within the same paging cycle (i.e., the target paging cycle), the base station allocates paging resources based on the coverage enhancement level. One paging resource area is a paging time set composed of paging times of terminals with the same coverage enhancement level. Different paging resource zones are not intersected with each other, and the union of a plurality of paging resource zones contained in the target paging cycle is the whole paging resource of the target paging cycle.

Preferably, if the number of the coverage enhancement level classes supported by the wireless communication system is m, the number of the paging resource regions is m when the paging resources in the target paging cycle are divided into a plurality of paging resource regions; m is an integer greater than or equal to 2.

For example, if the number of levels of the coverage enhancement level CEL supported by the wireless communication system is 3, specifically including CEL ═ 0, CEL ═ 1, and CEL ═ 2, the paging resource in the target paging cycle is divided into 3 paging areas, which are the first paging resource area, the second paging resource area, and the third paging resource area, respectively; and the CEL is 0 and corresponds to the first paging resource zone, the CEL is 1 and corresponds to the second paging resource zone, and the CEL is 2 and corresponds to the third paging resource zone. It should be noted that the first paging resource region, the second paging resource region, and the third paging resource region are not intersected with each other, and a union of the first paging resource region, the second paging resource region, and the third paging resource region is an entire paging resource of the target paging cycle.

Preferably, in the above embodiment of the present invention, any two adjacent target paging cycles are consecutive paging cycles; as shown in fig. 4, the base station sets each paging cycle as a target paging cycle, in other words, divides the paging resource of each paging cycle into a plurality of paging resource regions according to the number of levels of the coverage enhancement level.

It should be noted that, under the condition of multiple carriers, the base station may divide the paging cycle corresponding to each carrier into multiple paging resource regions according to the number of levels of the coverage enhancement level; the base station may also divide the paging cycle corresponding to some of the carriers into a plurality of paging resource regions according to the level number of the coverage enhancement level. At this time, the carrier waves corresponding to the paging cycles divided into a plurality of paging resource areas can be used for bearing the paging channel of the new version terminal; and carriers corresponding to a paging cycle that is not divided into a plurality of paging resource regions may be used to carry paging channels of legacy terminals.

The old version terminal specifically refers to a terminal which carries out paging monitoring according to the existing standard or protocol; and the new edition terminal specifically refers to a terminal which carries out paging monitoring according to the mode provided by the application.

For example, as shown in fig. 5, the base station supports carrier 1 and carrier 2, and the base station only divides the paging cycle corresponding to carrier 2 into a plurality of paging resource regions according to the number of levels of the coverage enhancement level; accordingly, for legacy terminals, the paging channel uses carrier 1; for new releases of terminals, the paging channel uses carrier 2, i.e. the base station can be compatible with existing terminals.

Alternatively, any two adjacent target paging cycles are non-consecutive paging cycles. The above-described embodiments of the present invention also provide another way to be compatible with existing terminals (i.e., the above-described legacy terminals), i.e., paging resource regions are divided every P-1 paging cycles based on the number of levels covering the enhancement level. The new terminal transmits a paging message in a paging cycle divided into a plurality of paging resource regions; and the legacy terminal transmits a paging message in a paging cycle that is not divided into a plurality of paging resource regions.

For example, as shown in fig. 6, when P is 2, the time interval between any adjacent target paging cycles is equal to the time length when P-1 is 1 paging cycle, that is, one target paging cycle is configured every 1 normal paging cycle, the base station transmits the paging message of the old version terminal in the normal paging cycle, and transmits the paging message of the new version terminal in the target paging cycle.

Further, in the foregoing embodiment of the present invention, step 12 includes:

Preferably, the step of obtaining the information about the division ratio of the paging resources in the target paging cycle includes:

When the base station or MME configures the division ratio information, the base station or MME can configure the division ratio information by referring to past paging experience; if there is no past paging experience, the configuration may be performed according to a default ratio, which is not specifically limited herein.

Bearing the above example, after step 32 in the embodiment of the present invention, the processing method further includes:

sending the configuration information of a plurality of paging resource areas contained in a target paging cycle to a terminal; wherein the configuration information of the paging resource zone comprises: the number of paging frames contained in each of the paging resource regions, the location information of the paging frames contained in each of the paging resource regions, and the coverage enhancement levels corresponding to each of the paging resource regions. Preferably, the location information of the paging frame included in each of the plurality of paging resource areas includes: the paging resource distinguishes a start position and/or an end position of a paging frame included therein.

Preferably, the base station may inform the terminal of the configuration information through a broadcast message; meanwhile, the base station can also broadcast basic paging messages such as the paging cycle T, the paging density nB and the like to the terminal through the broadcast message, and the basic paging messages are used for the terminal to determine the paging position PF/PO.

Further, after the step of sending the configuration information of the plurality of paging resource zones to the terminal, the processing method further includes:

Preferably, the base station receives a paging indication (including a paging message and a first coverage enhancement level) from the MME, and the base station first extracts the first coverage enhancement level to determine on which paging resource region the paging message is sent. The specific paging frame PF/specific paging occasion PO sent by the paging message is calculated by a default algorithm corresponding to the coverage enhancement level.

Preferably, the step of sending the paging message carried by the paging indicator to the terminal of the first coverage enhancement level in the first paging resource region includes:

Preferably, the step of determining a paging occasion PO for transmitting the paging message in the first paging resource region includes:

Preferably, as shown in fig. 4, 5 and 6, the step of determining a paging frame PF used for sending the paging message in the first paging resource region includes:

PF＝(HFN*1024+SFN)mod(P*T)＝(TdivN)*A+(TdivN)*(UE-IDmodB)；

As shown in fig. 4, 5 and 6, in the target paging cycle, the base station divides the paging resource into 3 paging resource regions from left to right based on 3 coverage enhancement levels of CEL ═ 0, CEL ═ 1 and CEL ═ 2, and each paging resource region can be used to transmit a paging message corresponding to the coverage enhancement level. The target paging cycle has N paging frames, so the base station reserves x PFs for CEL ═ 0, reserves y PFs for CEL ═ 1, and reserves z PFs for CEL ═ 2; then x + y + z equals N. Let x: y: z ═ a: b: c, and a + b + c ═ 1.

For each terminal with enhanced coverage level, the paging time is limited to a certain area in the paging cycle, so the algorithm for determining the paging location PF/PO is changed accordingly. For CEL being 0, the starting position of the paging resource corresponding to the coverage enhancement level is the 1 st paging frame of the paging cycle, and the ending position is the x-th paging frame; for CEL being 1, the starting position of the paging resource corresponding to the coverage enhancement level is the x +1 th paging frame in the paging cycle, and the ending position is the x + y th paging frame; for CEL is 2, the starting position of the paging resource corresponding to the coverage enhancement level is the x + y +1 th paging frame in the paging cycle, and the ending position is the x + y + z th paging frame.

As shown in fig. 4 and 5, any adjacent target paging cycles are consecutive paging cycles, that is, the time interval between any adjacent target paging cycles is equal to 0, that is, the time length of P-1 paging cycles is equal to 0, that is, P is equal to 1. Therefore, the PF determination formula corresponding to each coverage enhancement level is:

CEL＝0：

PF＝(HFN*1024+SFN)modT＝(TdivN)*(UE-IDmodx)；

CEL＝1：

PF＝(HFN*1024+SFN)modT＝(TdivN)*x+(TdivN)*(UE-IDmody)；

CEL＝2：

PF＝(HFN*1024+SFN)modT＝(TdivN)*(x+y)+(TdivN)*(UE-IDmodz)。

in this case, since any adjacent target paging cycle is a continuous paging cycle, the first equation may be modified as follows:

PF＝SNFmodT＝(TdivN)*A+(TdivN)*(UE-IDmodB)；

when any adjacent target paging cycle is a continuous paging cycle, the calculation results of the paging frames PF obtained before and after the first formula is deformed are the same.

As shown in fig. 6, any adjacent target paging cycle is a discontinuous paging cycle, and the time interval between any adjacent target paging cycles is equal to the time length of 1 paging cycle, i.e., P-1 is 1, and then P is 2. Therefore, the PF determination formula corresponding to each coverage enhancement level is:

CEL＝0：

PF＝(HFN*1024+SFN)mod2T＝(TdivN)*(UE-IDmodx)；

CEL＝1：

PF＝(HFN*1024+SFN)mod2T＝(TdivN)*x+(TdivN)*(UE-IDmody)；

CEL＝2：

PF＝(HFN*1024+SFN)mod2T＝(TdivN)*(x+y)+(TdivN)*(UE-IDmodz)。

preferably, in the first formula, the UE _ ID is equal to the terminal IMSI mod 4096.

Receiving the above example, the step of determining the paging occasion PO for transmitting the paging message in the paging frame PF includes:

Preferably, the paging occasion PO is not directly calculated by a formula, and is calculated by the first parameter N_sAnd the second parameter i-s, so that the first parameter N is determined_sAnd the second parameter i-s, the unique paging occasion PO can be determined.

Specifically, the PO determination formula corresponding to each coverage enhancement level is:

CEL＝0：N_s＝max(1，nB/T)；

i-s＝floor(UE-ID/x)modN_s；

CEL＝1：N_s＝max(1，nB/T)；

i-s＝floor(UE-ID/y)modN_s；

CEL＝2：N_s＝max(1，nB/T)；

i-s＝floor(UE-ID/z)modN_s。

bearing the above example, after the step of sending the paging message carried by the paging indication to the terminal of the first coverage enhancement level in the first paging resource region, the processing method further includes:

if the base station does not page the terminal in the first paging resource area for a plurality of times continuously, the base station transfers to a second paging resource area corresponding to a second coverage enhancement level to send the paging message to the terminal of the first coverage enhancement level; wherein a difference between the second coverage enhancement level and the first coverage enhancement level is greater than or equal to 1. For example, the paging message is transmitted by transferring from the paging resource region corresponding to CEL ═ 0 to the paging resource region corresponding to CEL ═ 1.

If the base station does not page the terminal for Q (Q is more than or equal to 1) times continuously, the coverage environment of the terminal is considered to be deteriorated, the base station can transfer to a paging resource corresponding to the next coverage enhancement grade to send a paging message, and the specific paging time PF/PO is calculated by a default algorithm corresponding to the next coverage enhancement grade. Wherein, Q must be reasonably configured so as to satisfy: before the base station transfers to the paging resource corresponding to the next coverage enhancement grade to send the paging message, the terminal has already transferred to the next coverage enhancement grade to wait for receiving the paging. And if the next coverage enhancement grade does not exist, the base station continues to send the paging information on the paging resource corresponding to the current coverage enhancement grade. The base station judges that the paging fails and a subsequent processing mechanism is to keep synchronous with the terminal.

In summary, in the above embodiments of the present invention, the paging resource of the target paging cycle is divided into a plurality of paging resource regions, so that the paging message is sent in the paging resource region corresponding to the coverage enhancement level; because different coverage enhancement levels correspond to different paging resource areas, the paging messages of different coverage enhancement levels cannot collide, and the paging messages cannot be delayed, so that the problem of paging delay is solved, and the user experience of delay-sensitive users is improved.

As shown in fig. 7, an embodiment of the present invention further provides a paging method, applied to a terminal, including:

step 71, determining the coverage enhancement grade of the terminal as a first coverage enhancement grade;

step 72, determining a first paging resource area corresponding to the first coverage enhancement level according to the first coverage enhancement level;

step 73, listening for paging messages on said first paging resource region.

In the above embodiment of the present invention, the terminal can determine the first paging resource region based on the first coverage enhancement level of the terminal, so that the terminal only monitors the paging message in the first paging resource region, thereby saving the power consumption of the terminal.

Preferably, before step 72, the method further comprises:

acquiring configuration information of a plurality of paging resource areas contained in a target paging cycle; wherein the configuration information of the paging resource zone comprises: the number of paging frames contained in each of the paging resource areas, the position information of the paging frames contained in each of the paging resource areas, and the coverage enhancement levels corresponding to each of the paging resource areas; preferably, the location information of the paging frame included in each of the plurality of paging resource areas includes: the paging resource distinguishes a start position and/or an end position of a paging frame included therein.

Accordingly, step 72 includes:

Preferably, the base station allocates paging resources based on the coverage enhancement level in the same paging cycle (i.e., the target paging cycle). One paging resource area is a paging time set composed of paging times of terminals with the same coverage enhancement level. Different paging resource zones are not intersected with each other, and the union of a plurality of paging resource zones contained in the target paging cycle is the whole paging resource of the target paging cycle.

Preferably, step 73 comprises:

and monitoring the paging message on the determined paging occasion PO.

Further, the step of determining a paging occasion PO for carrying the paging message in the first paging resource region includes:

Preferably, as shown in fig. 4, 5 and 6, the step of determining a paging frame PF used for carrying the paging message in the first paging resource region includes:

PF＝(HFN*1024+SFN)mod(P*T)＝(TdivN)*A+(TdivN)*(UE-IDmodB)；

CEL＝0：

PF＝(HFN*1024+SFN)modT＝(TdivN)*(UE-IDmodx)；

CEL＝1：

PF＝(HFN*1024+SFN)modT＝(TdivN)*x+(TdivN)*(UE-IDmody)；

CEL＝2：

PF＝(HFN*1024+SFN)modT＝(TdivN)*(x+y)+(TdivN)*(UE-IDmodz)。

If the terminal detects that the coverage environment where the terminal is located is already deteriorated (for example, it is determined by RSRP that the current downlink coverage enhancement level is changed from CEL-1 to CEL-2), the terminal transfers to a paging resource corresponding to the next coverage enhancement level to receive a paging message, and the specific paging time PF/PO is calculated by a default algorithm corresponding to the next coverage enhancement level. If the next coverage enhancement grade does not exist, the terminal continues to monitor the paging information on the paging resource corresponding to the current coverage enhancement grade. The terminal judges that the paging fails and a subsequent processing mechanism is to keep synchronous with the base station.

In summary, in the embodiments of the present invention, the terminal can obtain the configuration information of the multiple paging resource regions included in the target paging cycle in advance, so as to determine the position of each paging resource region, the included paging frame PF, and the corresponding coverage enhancement level, and then the terminal can monitor the paging message only in the paging resource region corresponding to the coverage enhancement level based on the coverage enhancement level of the terminal, thereby saving the power consumption of the terminal.
