Description

Background

With the development of communication technology, more and more User Equipment (UE) (simply referred to as multi-card UE) having multiple Subscriber Identity Module (SIM) cards are available.

For multi-card UEs, the main feature is that they can camp on multiple communication systems simultaneously. One of the multi-card UEs may simultaneously reside in multiple communication systems for data transmission and reception, and reception and transmission are not affected by each other, while another multi-card UE may reside in multiple communication systems but reside in different communication systems in a time division manner, for example, the UE resides in communication system 1 in time period 1 and listens for a paging message (paging) and resides in communication system 2 in time period 2.

Detailed Description

The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are some, not all, embodiments of the present invention. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.

Some terms involved in the embodiments of the present invention are explained below for the convenience of the reader:

1. paging message (paging)

In the prior art, when a certain communication system needs to transmit data to a UE, the communication system may send paging to the UE through an air interface. Namely, the functions of paging specifically include: sending a call request to the idle UE, notifying the UE of a change in System information, notifying the UE of the start of receiving Earthquake and tsunami warning information (ETWS), and notifying the UE of the start of receiving a Commercial Mobile Alert Service (CMAS) notification.

Illustratively, the paging supports Discontinuous Reception (DRX), and if the UE turns on the DRX function, the UE monitors the paging of the UE only at a transmission location corresponding to the UE when the UE is in an idle state.

In general, a radio Frame for transmitting a Paging is called a Paging Frame (PF), a subframe for transmitting a Paging in the Paging Frame is called a Paging Occasion (PO), and at least one PO may be included in one PF. One transmission location corresponding to the UE may be a PO in one PF.

2. Ns (paging density)

Generally, one system corresponds to one Ns, that is, all UEs in one communication system correspond to the same Ns, and the Ns of one UE is used to indicate the number of transmission positions used for transmitting paging in one radio frame in the corresponding communication system.

1): for a Long Term Evolution (LTE) system, a paging frame where a paging corresponding to any UE is located may be calculated according to the following formula (1), that is, a System Frame Number (SFN) of the PF is calculated based on the formula (1), where the bit length of the SFN is 10 bits and a value is 0 to 1023 in a normal case; the PO for transmitting the paging corresponding to the UE in the PF can be calculated according to the following formula (2), i.e., the index number i _ s of the PO is calculated based on the formula (2).

SFNmodT ═ t divvn (UE _ ID/N) formula (1);

i _ s ═ floor (UE _ ID/N) modNs equation (2);

wherein, the above T is used to represent a DRX cycle, and is configured by the RRC layer device, and the value of T may be: rf32, rf64, rf128 and rf 256; the value of N may be: min (T, nB), where nB may be: 4T, 2T, T, T/2, T/4, T/8, T/16, T/32.

For example, when the nB value is greater than or equal to 1, nB may be used to indicate a paging density, where the larger the nB value is, for example, when nB is 4, it indicates that 4 POs are included in one PF; when nB ═ 2, it means that 2 POs are included in one PF; when nB is less than 1, Ns indicates the paging density, Ns ═ max (1, nB/T), and in general, Ns may take the following value: 1. 2 or 4; when Ns ═ 1, it means that 1 PO is included in one PF; when Ns is 2, it means that 2 POs are included in one PF; when Ns is 4, it means that 4 POs are included in one PF.

The UE _ ID is an identifier of the SIM card of the UE, that is, the PF corresponding to one SIM card is calculated according to the formula (1), and the PO in the PF corresponding to one SIM card is calculated according to the formula (2). Illustratively, the identifier of the SIM card includes any one of: international Mobile Subscriber Identity (IMSI), 5G S-Temporary Mobile subscription identity (5G S-temporal Mobile subscription identity, 5G-S-IMSI).

For example, i _ s represents an index of the subframe pattern, and the position of the PO in the PF can be searched according to table 1 or table 2 below. The correspondence relationship between i _ s and PO and Ns will be described below with two examples.

Example 1: taking a Frequency Division Duplex (FDD) system in the LTE system as an example, the corresponding relationship table of i _ s, PO, Ns is shown in table 1 below.

TABLE 1

Ns	PO when i_s＝0	PO when i_s＝1	PO when i_s＝2	PO when i_s＝3
					1	9	N/A	N/A	N/A
2	4	9	N/A	N/A
					4	0	4	5	9

Example 2: taking a TDD (Time Division Duplexing) system in the LTE system as an example, the corresponding relationship table of i _ s, PO, and Ns is shown in table 2 below. It should be noted that table 2 is applicable to all uplink/downlink configurations of the TDD system.

TABLE 2

Ns	PO when i_s＝0	PO when i_s＝1	PO when i_s＝2	PO when i_s＝3
					1	0	N/A	N/A	N/A
2	0	5	N/A	N/A
					4	0	1	5	6

As shown in tables 1 and 2, when Ns equals 1, it indicates that only 1 transmission position in a radio frame is used for transmitting paging; when Ns is equal to 2, 2 transmission positions in a wireless frame are indicated to be used for transmitting paging; when Ns equals 4, it indicates that there are 4 transmission positions in a radio frame for transmitting paging.

2): for a New Radio (NR) system, a paging frame where a paging corresponding to any UE is located may be calculated according to the following formula (3), that is, an SFN of the PF is calculated based on the formula (3), and a PO where the user transmits the paging corresponding to the UE in the PF may be calculated according to the formula (2), that is, an index i _ s of the PO is calculated based on the formula (2).

(SFN + PF _ offset) modT ═ TdivN (UE _ ID/N) formula (3);

wherein, the above T is used to indicate a DRX cycle of the UE, and if T is configured by RRC or an upper layer, T is determined by a minimum value among UE-specific DRX values and a default DRX in system information broadcasting, and if the UE-specific DRX value is not configured by RRC or an upper layer, the default value is used. The above N indicates the number of PFs in one DRX cycle. PF _ offset: indicating the offset used to determine the PF.

Among them, the protocol (TS 38.331) specifies: the value of N, and the value of PF _ offset, are determined by the parameter N and the paging frame offset. The System Information Block Type 1 (SIB 1) carries Ns, n, and PF offsets, and the length of the default DRX cycle. The SIB1 also carries the monitoring time of the first PDCCH corresponding to the paging time.

For the NR system, when the parameters of the search space of the listening paging are configured as: when the SearchSpaceID is 0, Ns may be 1 or 2, where Ns is 1, that is, a PF includes one PO, where the PO is a monitoring time for monitoring the first PDCCH of a paging in the PF, and when Ns is 2, that is, the PF includes two POs, where the first PO is a first half frame of the PF and the second PO is a second half frame of the PF; when the parameter configuration for monitoring the search space of the paging includes a SearchSpaceID value other than 0, the first PO includes "s" (i.e., "s" in Ns) PDCCH monitoring instants, the kth PDCCH monitoring instant in the PO is the corresponding kth SSB, and when an uplink symbol is encountered, the PDCCH monitoring instant skips the subframe and extends backward. If the monitoring time (first PDCCH-monitoring OccasionoOfPO) of the first PDCCH configured corresponding to the paging time is H, then the corresponding monitoring time of the H PDCCHs is moved backwards.

Wherein, S is determined according to the number of SSBs actually sent by the UE, that is, whether the SSBs indicated by SSB-PositionsInBurst in SIB1 actually send the SSBs affecting the calculation of the number of S.

For the UE _ ID, it should be noted that, for the LTE system, the UE _ ID may be IMSI mod 1024, and for the NR system, the UE ID may be 5G-S-IMSI mod 1024. If the UE does not have a 5G-S-IMSI, for example, when the UE is not already registered on the network, the UE _ ID value defaults to 0 in the formula.

3. Synchronization Signal Block (SSB) (SSB may also be referred to as SSBlock)

The SSB comprises: primary Synchronization Signal (PSS), Secondary Synchronization Signal (SSS), and Physical broadcast Signal (PBCH), PBCH-DMRS.

Specifically, when the core network device wants to page the UE1, it sends an indication message to the RAN device 1, and after receiving the indication message, the RAN device sends a paging message to the UE1 according to the target transmission mode.

The RAN device 102 described above: the Base Transceiver Station (BTS) may be a Base Transceiver Station (BTS) in a Global System for mobile communications (GSM) or Code Division Multiple Access (CDMA) network, or an nb (nodeb) in Wideband Code Division Multiple Access (WCDMA), or an eNB or enodeb (evolved nodeb) in LTE.

As an example, in the embodiment of the present invention, fig. 1 illustrates that the UE is a mobile phone.

The transmission method of the paging message according to the embodiment of the present invention is described below with reference to fig. 2. Fig. 2 is an interaction flow diagram of a method for transmitting a paging message according to an embodiment of the present invention, and as shown in fig. 2, the method for transmitting a paging message according to an embodiment of the present invention may specifically include steps 201 to 203:

step 201, the core network device sends indication information to the RAN device.

Accordingly, the RAN device receives the indication information from the core network device.

In this embodiment of the present invention, the indication information is used to indicate a target transmission mode, and the indication information is also used to instruct the RAN device to send the first paging to the UE according to the target transmission mode. The UE is a multi-card UE, namely the UE comprises M SIM cards, and M is an integer greater than 1.

In an embodiment of the present invention, the first paging includes paging corresponding to N SIM cards, where N is a positive integer and is less than or equal to M.

In an example, the N SIM cards are: and the SIM cards with the paging transmission positions overlapped with those of other SIM cards in the M SIM cards of the UE. For example, taking a multi-card UE including a SIM card 1, a SIM card 2, and a SIM card 3 as an example, if the transmission position of the paging of the SIM card 1 overlaps with the transmission position of the paging of the SIM card 2, the network device may send the paging of the SIM card 1 and/or the paging of the SIM card 2 to the UE according to the first transmission mode.

For example, in one scenario, for a first paging transmitted according to a target transmission manner, transmission positions of part or all of the paging corresponding to different SIM cards are different, that is, a transmission position of at least one paging of each of N SIM cards transmitted according to the first transmission manner is different from transmission positions of paging of other SIM cards.

Optionally, in this embodiment of the present invention, in a case that the UE is in an inactive state, the indication information may be sent by the core network device to the RAN device before the UE enters an inactive period. That is, when the UE is in the inactive state, step 201 may specifically include the following steps:

step 201a, before the UE enters an inactive period, the core network device sends indication information to the RAN device.

Illustratively, when the core network node determines that it needs to trigger the RAN device to send the paging of the UE, the paging of the UE may be transmitted from the anchor node to other nodes in an inactive paging area (inactive paging area) of the UE through an inter-network interface.

Step 202, the RAN device sends a first paging to the UE according to the target transmission mode.

For example, when the core network device needs to paging the UE, the core network device may send indication information to the RAN device corresponding to the UE, so that the RAN device may determine a target transmission method based on the indication information, and send a first paging to the UE based on the target transmission method.

Step 203, the UE receives the paging from the RAN device according to the target transmission mode.

It should be noted that the UE may determine the target transmission mode according to the related parameter of the UE, or may determine the target transmission mode according to an agreed protocol, which is not specifically limited in this embodiment of the present invention.

Optionally, in an embodiment of the present invention, the target transmission manner includes at least one of the following: for a second paging corresponding to one SIM card, 1) repeatedly transmitting the second paging at X first transmission positions, 2) transmitting the second paging at a predetermined offset and/or a predetermined offset direction, and 3) transmitting the second paging at the second transmission position. The second transmission position is different from an original transmission position used for transmitting the second paging, and X is an integer greater than 1. The second paging corresponding to one SIM card specifically refers to all paging of the SIM card.

It should be noted that the three transmission modes may be implemented individually or in combination, and the present invention is not limited to this.

1): the transmission mode for repeatedly transmitting the second paging at the X first transmission positions can be implemented by at least the following two implementation modes:

in a first possible implementation: the second paging may be repeatedly transmitted at the X first transmission locations according to the first identifier corresponding to the UE. Wherein, the first flag is used to indicate a third transmission position for transmitting a paging in a radio frame, that is, Ns in the present document, and the X first transmission positions are: x third transmission positions in the at least one first radio frame.

For example, the first identifier Ns corresponding to the UE is taken as an example for explanation.

Example 1: when Ns is 1, it indicates that there is only one transmission location 1 in each radio frame for transmitting the paging, and the RAN device may select transmission location 1 in at least two radio frames to transmit the second paging.

Example 2: when Ns equals 2, it indicates that each radio frame contains two transmission locations 2 for transmitting paging, and at this time, the RAN apparatus may select some or all of the transmission locations 2 in each radio frame in at least one radio frame to transmit the second paging.

For example, in the case that Ns is equal to 4, taking the RAN device as an example to select the original transmission location of the second paging, if the radio frame in which the original transmission location is located is the radio frame K, the RAN device may select the transmission locations corresponding to i _ s ═ 0 and i _ s ═ 2 in the radio frame K to repeatedly transmit the second paging; or, the RAN device may select transmission locations corresponding to i _ s ═ 0 and i _ s ═ 3 in the radio frame K to repeatedly transmit the second paging; or, the RAN device may select transmission positions corresponding to i _ s ═ 1 and i _ s ═ 2 in the radio frame K to repeatedly transmit the second paging; or, the RAN device may select transmission positions corresponding to i _ s ═ 1 and i _ s ═ 3 in the radio frame K to repeatedly transmit the second paging; or, the RAN device may select transmission positions corresponding to i _ s ═ 2 and i _ s ═ 3 in the radio frame K to repeatedly transmit the second paging; or, the RAN device may select a transmission location corresponding to i _ s ═ 0, i _ s ═ 1, and i _ s ═ 2 in the radio frame K, to repeatedly transmit the second paging; or, the RAN device may select a transmission location corresponding to i _ s ═ 0, i _ s ═ 2, and i _ s ═ 3 in the radio frame K, to repeatedly transmit the second paging; or, the RAN device may select a transmission location corresponding to i _ s ═ 1, i _ s ═ 2, and i _ s ═ 3 in the radio frame K, to repeatedly transmit the second paging; alternatively, the RAN device may select a transmission location corresponding to i _ s ═ 0, i _ s ═ 1, i _ s ═ 2, and i _ s ═ 3 in the radio frame K to repeatedly transmit the second paging.

In a second possible implementation: the X first transmission positions are: x transmission locations in at least one first radio frame for transmitting a paging; wherein the at least one first radio frame at least comprises: a target radio frame, wherein the target radio frame is: adjacent radio frames of the second radio frame and/or at least one radio frame apart from the second radio frame, the second radio frame being a raw radio frame for transmitting a second paging. It should be noted that the adjacent radio frames include a front adjacent radio frame and/or a rear adjacent radio frame.

For example, if the original transmission location of the second paging is the radio frame K and the predetermined repetition number is 2, the second paging may be retransmitted at the transmission location 1 of the radio frame K and the transmission location 1 of the radio frame K +1, or retransmitted at the transmission location 1 of the radio frame K and the transmission location 1 of the radio frame K-1.

2): for a transmission mode for transmitting a second paging at a second transmission location:

in one example, the second transmission position is: a transmission location in a target radio frame for transmitting a paging, the target radio frame being: the second radio frame is adjacent to the first radio frame or separated from the first radio frame by at least one radio frame, and the first radio frame is a raw radio frame for transmitting the first paging.

In another example, the second transmission position is a predetermined transmission position, which is predefined or protocol-specified or network-preconfigured. For example, a special location, which is not usually the location of the subframe where the system message is located, is provided to avoid the paging from colliding with the system message.

It should be noted that the second transmission position is predefined or protocol-specified or network-preconfigured.

It should be noted that, when there are a plurality of second transmission positions, the transmission mode for transmitting the second paging at the second transmission position is another special repeat transmission mode.

Optionally, in an embodiment of the present invention, for a paging of a SIM card, the indication information includes: an identifier of a target SIM card, wherein the target SIM card comprises: the SIM card and the SIM card in the UE which has an association relation with the SIM card.

For example, if the IMSI1 of the SIM card 1 in the UE and the IMSI2 of the SIM card 2 have a binding relationship, when the core network device wants to pad the SIM card 1 of the UE, the core network device sends the IMSI1 and the SIM card 2 to the RAN device to instruct the RAN device to perform paging enhancement on the paging of the SIM card 1, and the RAN device sends the paging of the SIM card 1 at both the transmission location of the paging of the SIM card 1 and the transmission location of the paging of the SIM card 2.

It should be noted that the association relationship may be stored in the core network device, the RAN device, and the UE, respectively.

Optionally, in this embodiment of the present invention, sending the indication information to the RAN device by the core network device may be implemented by two implementation manners:

a first possible implementation:

illustratively, in the embodiment of the present invention, the following step a1 is further included before step 201:

step a1, the core network device receives the first information from the UE.

With reference to step a1, the step 201 specifically includes the following step a 2:

step a2, the core network device sends indication information to the RAN device according to the first information.

The first information is used for indicating the target transmission mode.

Optionally, the first information is used to indicate at least one of: 1) the UE comprises M SIM cards; 2) whether Radio Access Technologies (RATs) of at least two of the M SIM cards are the same; 3) whether operators of at least two SIM cards in the M SIM cards are the same; 4) whether the transmission positions of the paging corresponding to at least two of the M SIM cards are overlapped.

Illustratively, the information 4 for the above includes at least two cases: 1) the transmission positions of the paging corresponding to at least one connected SIM card and the paging corresponding to at least one idle SIM card in the M SIM cards are overlapped; 2) the transmission positions of the paging corresponding to at least two SIM cards in the idle state in the M SIM cards are overlapped.

For example, the core network device determines the overlapping condition of the transmission positions of paging of multiple SIM cards in the UE according to the first information, so as to determine the paging transmission mode when paging the UE based on different overlapping scenarios.

Example 1: before step a1, the method for transmitting a paging message according to the embodiment of the present invention further includes step a11 and step a 12:

step A11: the RAN device receives first information from the UE.

Step A12: the RAN equipment sends the first information to the core network equipment.

Example 2: before step a1, the method for transmitting a paging message according to the embodiment of the present invention further includes:

step A13: the UE sends first information to the core network equipment.

A second possible implementation:

illustratively, in the embodiment of the present invention, the following step B1 is further included before the step 201:

step B1, the core network device receives the second information from the RAN device.

Wherein the second information is: and determining parameters for monitoring the paging moment in a cell controlled by the RAN equipment.

Optionally, the second information includes at least one of: 1) a first number; 2) "first PDCCH-monitoring occasionOfPO", that is, the monitoring time of the first PDCCH corresponding to the paging time; 3) "nANdPaginFrameOffset" is abbreviated as: PF _ offset, which is the offset of the listening time for listening to paging under the cell controlled by the RAN device; 4) configuration information of a Discontinuous Reception (DRX) cycle of a cell controlled by RAN equipment; 5) the number of synchronization signal blocks SSB of the cell controlled by the RAN equipment; 6) a parameter for indicating whether all or part of the SSBs are transmitted in a cell controlled by the RAN equipment; 7) the sub-carrier spacing of the cell controlled by the RAN equipment; 8) identification of the cell controlled by the RAN equipment. Wherein the first number is: the number of transmission locations in a radio frame used for transmitting paging in a cell controlled by the RAN equipment.

With reference to step a1, the step 201 can be specifically executed by the following step B2:

step B2, if it is determined that the paging is transmitted according to the target transmission mode based on the second information and the card identifiers of the M SIM cards, the core network device sends indication information to the RAN device.

For example, after receiving the second information, the core network device may calculate a transmission position of a paging corresponding to each SIM card based on the second information and card identifiers of M SIM cards, and then may determine whether there is a situation that transmission positions overlap from the transmission position of the paging corresponding to each SIM card, so as to determine a target transmission mode based on the overlapping situation.

In the method for transmitting a paging message provided in the embodiment of the present invention, after receiving indication information from a core network device, a RAN device may send a first paging (including a paging corresponding to N SIM cards) to a UE according to a target transmission mode according to the indication of the indication information, where the target transmission mode includes at least one of: for a second paging of one SIM card, repeatedly transmitting the second paging at X first transmission positions, performing offset transmission on the second paging according to a preset offset and/or a preset offset direction, and transmitting the second paging at a second transmission position; therefore, the transmission position of the second paging is changed or increased, the problem that the paging is lost due to overlapping of the transmission positions of the paging when the multi-card UE monitors the paging of different SIM cards is solved, and the communication efficiency and efficiency are improved.
