Referring to fig. 1, fig. 1 is a block diagram of a wireless communication system to which an embodiment of the present invention is applicable. The wireless communication system includes a terminal 11 and a network-side device 12. The terminal 11 may also be referred to as a terminal Device or a terminal (UE), where the terminal 11 may be a Mobile phone, a Tablet Personal Computer (Tablet Personal Computer), a Laptop Computer (Laptop Computer), a Personal Digital Assistant (PDA), a Mobile Internet Device (MID), a Wearable Device (Wearable Device), or a vehicle-mounted Device, and the specific type of the terminal 11 is not limited in the embodiment of the present invention. The network-side device 12 may be a Base Station or a core network, wherein the Base Station may be a 5G or later-version Base Station (e.g., a gNB, a 5G NR NB, etc.), or a Base Station in other communication systems (e.g., an eNB, a WLAN access point, or other access points, etc.), or a location server (e.g., an E-SMLC or an lmf (location Manager function)), wherein the Base Station may be referred to as a node B, an evolved node B, an access point, a Base Transceiver Station (BTS), a radio Base Station, a radio Transceiver, a Basic Service Set (BSS), an Extended Service Set (ESS), a node B, an evolved node B (eNB), a home node B, a home evolved node B, a WLAN access point, a WiFi node, or some other suitable terminology in the field, as long as the same technical effect is achieved, the base station is not limited to a specific technical vocabulary, and it should be noted that, in the embodiment of the present invention, only the base station in the NR system is taken as an example, but the specific type of the base station is not limited.

The base stations may communicate with the terminals 11 under the control of a base station controller, which may be part of the core network or some of the base stations in various examples. Some base stations may communicate control information or user data with the core network through a backhaul. In some examples, some of the base stations may communicate with each other, directly or indirectly, over backhaul links, which may be wired or wireless communication links. A wireless communication system may support operation on multiple carriers (waveform signals of different frequencies). A multi-carrier transmitter can transmit modulated signals on the multiple carriers simultaneously. For example, each communication link may be a multi-carrier signal modulated according to various radio technologies. Each modulated signal may be transmitted on a different carrier and may carry control information (e.g., reference signals, control channels, etc.), overhead information, data, and so on.

The base station may communicate wirelessly with the terminal 11 via one or more access point antennas. Each base station may provide communication coverage for a respective coverage area. The coverage area of an access point may be divided into sectors that form only a portion of the coverage area. A wireless communication system may include different types of base stations (e.g., macro, micro, or pico base stations). The base stations may also utilize different radio technologies, such as cellular or WLAN radio access technologies. The base stations may be associated with the same or different access networks or operator deployments. The coverage areas of different base stations (including coverage areas of base stations of the same or different types, coverage areas utilizing the same or different radio technologies, or coverage areas belonging to the same or different access networks) may overlap.

The communication link in the wireless communication system may include an Uplink for carrying Uplink (UL) transmission (e.g., from the terminal 11 to the network side device 12) or a Downlink for carrying Downlink (DL) transmission (e.g., from the network side device 12 to the terminal 11). The UL transmission may also be referred to as reverse link transmission, while the DL transmission may also be referred to as forward link transmission. Downlink transmissions may be made using licensed frequency bands, unlicensed frequency bands, or both. Similarly, uplink transmissions may be made using licensed frequency bands, unlicensed frequency bands, or both.

A Long Term Evolution (LTE) system has a paging function, where a terminal (UE) needs to receive information from a network to find the UE to a specific location. Calculating Paging Frame (Paging Frame)_，PF) SFN and Paging Observation (Paging Obrasion)_，The formula of PO) i _ s is formula (1) and formula (2):

SFN mod T＝(T div N)*(UE_ID mod N) (1)

i_s＝floor(UE_ID/N) mod Ns (2)

the PO may include subframes for paging messages of the terminal, and the PF may include one or more POs for radio frames in which paging messages are sent by the user. When Discontinuous Reception (DRX) is turned on, the terminal monitors only the PO belonging to the terminal in the DRX cycle in order to save power.

Wherein the frame number is from 0 to 1023;

UE _ ID: the terminal identifier is an International Mobile Subscriber Identity (IMSI) MODE 1024, that is, the terminal identifier can be divided into 1024 groups according to the IMSI;

t: the DRX period is determined as rf32, rf64, rf128 and rf256, and parameters are configured by a Radio Resource Control (RRC) layer;

i _ s: the mode is a subframe mode and is obtained through query;

the value of N is min (T, nB);

the value of Ns is max (1, nB/T), and the value can be specifically 1, 2 or 4;

wherein, the value of nB is 4T,2T, T, T/2, T/4, T/8, T/16 and T/32. nB is the paging density, and the larger the value is, the larger the paging density is. For example, nB-4 indicates 4 POs in a radio frame, and when the value is less than 1, the paging density configuration Ns-1 indicates 1 paging PO in a radio frame, and 2 indicates 2 POs.

In the New Radio (NR) system, New variables are introduced so that the calculation of PF and PO is slightly changed, wherein the SFN and i _ s of PO of PF can be calculated according to the following formula:

(SFN+PF_offset)mod T＝(T div N)*(UE_ID mod N)； (3)

i_s＝floor(UE_ID/N)mod Ns； (4)

it can be seen that the PF _ offset parameter is added to the formula for calculating PF. PF _ offset is the calculated offset from which the PF position is determined.

When SearchSpaceId is configured to the search space for listening to the paging as 0, Ns is 1 or 2. When Ns is 1, that is, there is only one PO, the PO starts from the monitoring time when monitoring the first Physical Downlink Control Channel (PDCCH) in the PF for paging. When Ns is 2, PO (first PO) is either the first half of the PF or PO (second PO) is the second half of the PF.

When other SearchSpaceId besides SearchSpaceId 0 is configured to the search space for monitoring paging, the first PO continues to have "S" PDCCH monitoring time, where the number of "S" is determined by the number of actually transmitted Synchronization Signal Blocks (SSBs). That is, whether the SSB-positioninburst SSB indicated in the System signal Block (SIB) 1 is actually transmitted or not affects the calculation of the "S" number. The kth PDCCH monitoring time in the PO is the corresponding kth SSB, and when an uplink symbol is encountered, the PDCCH monitoring time also needs to skip the backward delay.

If firstPDCCH-MonitoringOccasionoOfPO is configured, the monitoring time of the firstPDCCH-MonitoringOccasionoOfPO needs to be correspondingly shifted backwards for one PDCCH monitoring time.

In the above formulas (3) and (4), T is the DRX cycle, N is the total number of paging frames in T, Ns is the number of paging occasions in one paging frame, and UE _ ID is the terminal identifier and is obtained as 5G-S-TMSI mod 1024.

The parameters Ns, firstdcch-monitorasionofpo, nAndPagingFrameOffset and the default length of the DRX cycle are contained in SIB1, and the values of N and PF _ offset are derived from the parameters nAndPagingFrameOffset. If the terminal does not have 5G-S-TMSI, the UE uses UE _ ID 0. The 5G-S-TMSI is a 48-bit string with the leftmost bit representing the most significant bit.

Currently, there are not only single-card terminals but also dual-card or multi-card terminals. The multi-card terminal is characterized in that the multi-card terminal can reside in a plurality of networks at the same time, but the multi-card terminal has different realization modes, and some terminals can simultaneously transmit and receive in the plurality of networks without mutual influence on the transmission and the reception. However, there is also a multi-card terminal, although the terminal may reside in multiple networks simultaneously, it may reside in multiple networks, such as two networks, in a time division manner, that is, the terminal may reside in the network a and listen to the paging of the network a for a while, and may reside in the network B and listen to the paging of the network B for a while; or the network A is connected with the network for receiving and sending data for a period of time, and the network B receives the paging for a period of time; or receive data on network a for a period of time and establish a connection to network B or receive transmit and receive data for a period of time.

For a multi-card terminal, if the terminal cannot receive paging information in all networks at one time, the paging information needs to be received in different networks in a time division manner. A missing paging on a card occurs when the moments of receiving two paging overlap in time (overlap). When the time for receiving two paging is long in time distance, the system frequently wakes up to receive data, and high system power consumption is caused; when the time of receiving two paging can be combined and received in time, if the distance between two paging is large, the system power consumption will be high.

An embodiment of the present invention provides a paging method, which is applied to a communication device, where the communication device includes at least two terminal UEs, as shown in fig. 2, the paging method includes:

step 101: sending a paging position adjustment request to a network side device, requesting to adjust a paging position of a first UE of the at least two UEs, where the at least two UEs include the first UE and a second UE other than the first UE, and the paging position includes at least one of: paging frame, paging occasion.

In this embodiment, the communication device sends a paging position adjustment request to the network side device to request adjustment of the paging position of the first UE in the at least two terminals, so that the paging receiving position of the terminal can be adjusted, the paging positions of the terminals can be combined, or the paging positions of the terminals are closely arranged, which not only can avoid receiving paging collision when the communication device resides in multiple networks, but also can achieve the effect of saving power of the communication device system.

Wherein, the communication device refers to a physical mobile communication device with 4G, 5G and/or next generation wireless communication capability, such as a multi-card mobile phone; each UE is a logical entity with 4G, 5G, and/or next generation wireless communication capabilities corresponding to a Subscriber Identity Module (SIM) card.

In this embodiment, the network side device is requested to adjust the paging frame and/or the paging occasion of the UE, so that the paging positions of multiple UEs reach a reasonable paging interval, and the paging positions of multiple UEs are combined or closely arranged, thereby achieving the effect of saving power of the communication device system. The present embodiment may adjust the paging location of one or more UEs, and any UE can initiate the paging location adjustment request.

The communication device requests the network side device to allocate a new parameter for paging location calculation, the paging location adjustment request may include a paging location adjustment parameter for calculating a new UE ID, and the paging location adjustment request may include at least one of the following paging location adjustment parameters:

request cause, such as multi-card, power save, paging, etc.;

target Paging Position recommendation value, Target _ Paging _ Position, comprising PF and/or PO;

adjusting a recommended value Page _ Position _ adjust for offset;

the first UE global network identification recommended value, such as 5G-S-TMSI and IMSI;

when the paging position adjustment request carries the value of part of the bits of the first UE global network identity recommended value, the bit overhead can be reduced, and the value of the low X bit can contain most of effective information of the first UE global network identity recommended value;

a first UE identity recommendation value, such as 5G-S-TMSI mod 1024, IMSI mod 1024, etc.;

a part of bit values of the first UE identity recommended value, for example, a lowest X bit value, where X may be less than or equal to 10, and certainly, X is not limited to be less than or equal to 10 and may also be other values; it can also be (5G-S-TMSI mod 1024) mod N, (IMSI mod 1024) mod N, etc., where N is the total number of paging frames within DRX cycle T;

the first UE identifies a recommended value UEID _ adjust of the adjustment quantity;

the second UE identifies the UEID _ reference;

a paging location of the second UE, including PF and/or PO;

paging parameters for the second UE, including DRX cycle T, N, Ns, etc.;

a shortest Paging interval Min _ Paging _ distance, where the shortest Paging interval is a shortest interval between Paging occasions when the first UE and the second UE do not overlap to receive a Paging;

the paging frame offset recommendation value PF _ offset.

The communication device may request the network side device to adjust the paging location in multiple signaling messages, and the paging location adjustment request may be carried in at least one of the following messages:

registration Request messages, such as Registration Request, Registration Update, and the like, optionally, reasons for changing the terminal identifier may also be added to the Registration Request messages;

attach Request messages such as Attach Request, Reattach Request, etc.;

UE Assistance Information, such as UE Assistance Information;

a radio resource control message, such as RRC Resume.

After sending the paging location adjustment request to the network side device, the paging method further includes:

receiving the paging parameters configured by the network side equipment;

and determining the paging position of the first UE according to the paging parameter, so that the communication equipment can complete the adjustment of the paging position according to the paging parameter configured by the network side equipment, wherein the paging parameter configured by the network side equipment is the newly configured paging parameter after the network side equipment receives the paging position adjustment request.

In some embodiments, the paging parameters include at least one of:

a first UE whole network identifier configuration value, such as 5G-S-TMSI, a second IMSI and the like, wherein the second IMSI is an identifier which can be used for determining a paging position;

when the paging parameter includes the value of the partial bit of the first UE whole network identifier configuration value, the bit overhead can be reduced, and the value of the low X bit can contain most of effective information of the first UE whole network identifier configuration value;

a first UE identity configuration value, UE id _ new;

a part of bit values of the first UE identity configuration value, for example, a lowest X bit value, where X may be less than or equal to 10, and certainly, X is not limited to be less than or equal to 10 and may also be other values;

the first UE identifies an adjustment quantity configuration value, UEID _ adjust;

a paging frame offset configuration value PF _ offset, i.e., an offset used for PF determination defined by the protocol;

target Paging Position configuration values, Target _ Paging _ Position, including PF and/or PO;

the Paging Position adjustment offset configuration value Paging _ Position _ adjust.

Under the condition of ensuring that the paging position is within the expected range, the paging parameter newly configured by the network side device may not be identical to the recommended parameter in the paging position adjustment request sent by the communication device.

In the above embodiment, a distance between the paging location of the first UE and the paging location of the second UE is greater than a shortest paging interval or is 0, where the shortest paging interval is a shortest interval between paging occasions when the first UE and the second UE do not overlap and receive paging.

For the condition that Paging reception cannot be overlapped among multiple UEs, the Paging position needs to be adjusted to achieve Paging reception among the UEs without overlapping conflict, and meanwhile, the terminal does not need to sleep and wait among UE Paging. The UE that needs to adjust the Paging location determines the shortest Paging distance Min _ Paging _ distance. For example, the communication device includes UE1 and UE2, UE2 can adjust the Paging location after the Paging of UE1, and the minimum Paging distance Min _ Paging _ distance is the time from UE1 PO to UE2 PO, which is the time sufficient to perform the Paging reception, the post-Paging processing, part or all of the measurement task, the radio frequency conversion time of UE1, and the system wake-up, the network synchronization, the Paging reception preparation, etc. of UE 2. Of course, the UE2 can also adjust the Paging location before the UE1 pages, and the minimum Paging distance Min _ Paging _ distance is the time from the UE2 PO to the UE1 PO, which is the time sufficient to perform Paging reception, post-Paging processing, part or all of the measurement tasks, radio frequency conversion time, and system wake-up, network synchronization, Paging reception preparation, etc. of the UE1 for the UE 2.

The shortest Paging distance Min _ Paging _ distance may be determined by the terminal, or may be agreed by a protocol, such as 20 ms.

For the case where Paging reception can overlap between multiple UEs, the Paging interval between UEs is 0, i.e., pages of multiple UEs are temporally coordinated and merged together.

In a specific example, taking UE2 corresponding to SIM2, UE1 corresponding to SIM1, and UE2 Paging location adjusted to be after UE1 Paging location as an example, SIM1 has a current Paging location marked as reference location Paging _ Position _ reference, which includes PF, PO. The current Paging Position of the SIM2 whose Paging Position is to be adjusted is denoted as Paging _ Position, which includes PF and PO. The SIM2 expects a Paging location denoted as Target _ Paging _ Position, which contains PF, PO. The range of expected paging locations is then:

Target_Paging_Position>＝Paging_Position_reference+Min_Paging_distance

the paging position adjustment offset is:

Paging_Position_adjust＝Target_Paging_Position-Paging_Position

recording the current UE ID as UEID _ now, recording the adjusted UE ID as UEID _ new, and recording the UE ID adjustment amount as UEID _ adjust, wherein:

UEID_new＝UEID_now+UEID_adjust

wherein, Target _ Paging _ Position (PF, PO) and ue id _ new conform to the definition of the protocol:

(SFN+PF_offset)mod T＝(T div N)*(UE_ID mod N)；

i_s＝floor(UE_ID/N)mod Ns；

namely:

target PF satisfies: (SFN + PF _ offset) mod T ═ T div N (UEID _ new mod N)

Target PO satisfies: i _ s ═ floor (UEID _ new/N) mod Ns

An embodiment of the present invention further provides a paging method, which is applied to a network side device, and as shown in fig. 3, the paging method includes:

step 201: receiving a paging position adjustment request of communication equipment, and adjusting a paging position of a first UE (user equipment) in at least two terminals of the communication equipment according to the paging position adjustment request, wherein the at least two terminals comprise the first UE and a second UE except the first UE, and the paging position comprises at least one of the following: paging frame, paging occasion.

The paging location adjustment request may include a paging location adjustment parameter for calculating a new UE ID, and the paging location adjustment request may include at least one of the following paging location adjustment parameters:

request cause, such as multi-card, power save, paging, etc.;

adjusting a recommended value Page _ Position _ adjust for offset;

the second UE identifies the UEID _ reference;

a paging location of the second UE, including PF and/or PO;

paging parameters for the second UE, including DRX cycle T, N, Ns, etc.;

the paging frame offset recommendation value PF _ offset.

attach Request messages such as Attach Request, Reattach Request, etc.;

UE Assistance Information, such as UE Assistance Information;

a radio resource control message, such as RRC Resume.

After receiving the paging location adjustment request of the communication device, the paging method further includes:

sending the configured paging parameters to the communication device.

In some embodiments, the paging parameters include at least one of:

a first UE identity configuration value, UE id _ new;

The technical scheme of the invention is further described below by combining the attached drawings.

In a specific embodiment of the present invention, the paging location may be adjusted in case of paging collision. As shown in fig. 4, UE2 corresponds to SIM2, UE1 corresponds to SIM1, and the paging location of UE2 is adjusted to be after the paging location of UE 1. Before the Paging Position adjustment is performed, as shown in fig. 4, the communication device identifies a Paging collision between UE1 and UE2, determines an expected Paging Position Target _ Paging _ Position based on the shortest Paging distance Min _ Paging _ distance, determines a Paging Position adjustment parameter, and requests the network side to adjust the Paging Position; the communication equipment calculates a new paging position based on the new paging parameter sent by the network side, receives paging at the new paging position and can solve paging conflict.

In another embodiment of the present invention, the paging location may also be adjusted when paging does not conflict. As shown in fig. 5, UE2 corresponds to SIM2, UE1 corresponds to SIM1, and the communication device recognizes the paging distance between the two UEs, which requires a reduction in system power consumption. The communication equipment determines an expected Paging Position (Target _ Paging _ Position) based on the shortest Paging distance (Min _ Paging _ distance), determines a Paging Position adjusting parameter and requests a network side to adjust the Paging Position, calculates a new Paging Position based on the new Paging parameter sent by the network side, receives Paging at the new Paging Position, and improves the power saving performance.

In the embodiment of the invention, one communication device corresponds to M pieces of UE, M is an integer greater than or equal to 2, and at least UE1 and UE2 in the M pieces of UE reside (camp) in the same cell; the POs that UE1 and UE2 listen to do not overlap completely; the PO monitoring positions of UE1 and UE2 are adjusted together (time domain overlapping), and the communication device can complete the PO monitoring of UE1 and UE2 in one cell at a time, thereby achieving the power saving effect. The communication device may send a paging location adjustment request to the network side device to adjust the PO location monitored by the UE1 (or UE2) to overlap with the PO location monitored by the UE2 (or UE 1). In a specific example, the UE1 sends a paging location adjustment request, where the paging location adjustment request carries a parameter to indicate an adjustment target PO monitoring location, where the parameter may be "a value of 5G-S-TMSI recommended for allocation" or "a value of a part of bits of 5G-S-TMSI recommended for allocation" (for example, a value of the lowest X bit), "and X ≦ 10; optionally, in the paging location adjustment request sent by the UE1, the partial bits of the 5G-S-TMSI carried in the paging location adjustment request are the same as the corresponding bits of the 5G-S-TMSI of the UE 2.

The network side device, such as the NW, adjusts the PO location of the UE1 according to the received paging location adjustment request, for example, allocates a new 5G-S-TMSI to the UE, where the newly allocated 5G-S-TMSI meets the requirement of the parameter in the paging location adjustment request, for example, the corresponding bits of the allocated new 5G-S-TMSI are the same as the partial bits of the 5G-S-TMSI in the paging location adjustment request.

By the above method, the communication device can align partial bits (e.g., the lowest 10 bits) of the 5G-S-TMSI of UE1 and UE 2. Since the position of the PO is calculated by the lowest 10bit input parameter of the 5G-S-TMSI, the PO positions of UE1 and UE2 can be adjusted to coincide by the above method. The purpose of receiving the paging messages of two UEs by one PO monitoring is achieved, and therefore the power saving effect is achieved.
