The network device may be a device for communicating with the terminal device, and for example, may be a Base Transceiver Station (BTS) in a GSM system or a CDMA system, a Base Station (NodeB, NB) in a WCDMA system, an evolved node B (eNB, or eNodeB) in an LTE system, or may be a relay Station, an access point, a vehicle-mounted device, a wearable device, and a network-side device in a future 5G network or a network-side device in a future evolved PLMN network.
Fig. 1 is a schematic diagram of an application scenario of an embodiment of the present application. The communication system in fig. 1 may include a network device 10 and a terminal device 20. The network device 10 is used to provide a communication service for the terminal device 20 and access a core network, and the terminal device 20 may access the network by searching for a synchronization signal, a broadcast signal, or the like transmitted by the network device 10, thereby performing communication with the network. The arrows shown in fig. 1 may represent uplink/downlink transmissions over a cellular link between terminal device 20 and network device 10.
The network in this embodiment of the application may refer to a Public Land Mobile Network (PLMN), a Device to Device (D2D) network, a Machine to Machine/Man (M2M) network, or other networks, where fig. 1 is a simplified schematic diagram of an example, and the network may further include other terminal devices, which is not shown in fig. 1.
When the downlink data of the terminal device arrives, the network device may establish a signaling connection from the terminal device to the network device by paging the terminal device, thereby transmitting the downlink data.
Paging messages of 16 terminal devices can be carried in one PDSCH channel at most, the Paging messages of the terminal devices form a Paging Record List (Paging Record List), the terminal device reads each Paging Record (Paging Record) in the Paging Record List, and each Paging Record includes a device identifier (UE-IDentity, UE-ID) of the paged terminal device. If a certain terminal device finds that its own UE-ID is consistent with a certain UE-ID in a certain paging record list, it can judge that it is paged by the network device.
Since paging messages of multiple terminal devices are transmitted in one PDSCH, and the network device does not know the channel quality of idle (idle) terminal devices, the network device generally adopts a conservative Modulation and Coding Scheme (MCS), a lower code rate, or a larger scheduling bandwidth when sending the paging message to the terminal to ensure that the terminal device at the edge of the cell can receive the paging message.
In the 5G system, the transmission of the paging message needs to adopt a beam scanning manner to cover all downlink beams. When paging is performed in a beam scanning manner, a paging message needs to be repeatedly sent in all beam directions, thereby bringing about a large resource overhead.
In order to reduce the resource overhead of the paging message, the UE-ID carried in the paging message may be compressed and then transmitted, for example, the UE-ID may be compressed from 40 bits to 10 more bits. However, the problems that the compressed UE-ID may cause are: two new UE-IDs obtained after the two different UE-IDs are respectively compressed may be the same, so that when the network device sends a paging message to one of the terminal devices, both terminal devices are paged, thereby causing a problem of false paging.
The embodiment of the application provides that two sub-identifications, namely a first sub-identification and a second sub-identification, are generated based on the equipment identification of the terminal equipment, and the first sub-identification in the two sub-identifications is used for determining the transmission moment of the paging message carrying the second sub-identification, so that the network equipment can effectively page the terminal equipment based on the second sub-identification without causing large resource overhead, and even if the compressed second sub-identifications of different terminal equipment are the same, the terminal equipment can also effectively identify the paging message of the terminal equipment according to the transmission moment corresponding to the first sub-identification, thereby determining whether the terminal equipment is paged by the network equipment, and reducing error paging.
Fig. 2 is a schematic flow chart of a paging method according to an embodiment of the present application. The method shown in fig. 2 may be performed by a terminal device, which may be, for example, terminal device 20 shown in fig. 1. As shown in fig. 2, the paging method includes:
in 210, the terminal device determines a first sub-identity and a second sub-identity based on the device identity of the terminal device.
The embodiment of the application provides two ways for obtaining the first sub-identifier and the second sub-identifier. Described separately below.
Mode 1
Optionally, the device flag of the terminal device includes N bit values, where in 210, the terminal device determines the first sub identifier and the second sub identifier based on the device identifier of the terminal device, including: the terminal device determines M bit values of the N bit values as the first sub-identity, and determines the remaining N-M bit values of the N bit values except the M bit values as the second sub-identity, wherein N, M is a positive integer and M < N.
Optionally, the M bit values are first M bit values of the N bit values, and the N-M bit values are last N-M bit values of the N bit values.
For example, the UE-ID of the terminal device consists of N bit values, and assuming that N is 40 and M is 30, the first sub-identity UE-ID obtained by intercepting the UE-ID is obtained1May be a high 30 bit value, the second sub-identity UE-ID2May be the remaining 10-bit value.
For another example, assuming that N is 40 and M is 10, the first sub flag may be a high 10-bit value, and the second sub flag may be the remaining 30-bit value.
Therefore, the embodiment may obtain different sub-identifications, i.e. the first sub-identification and the second sub-identification, by intercepting the bit value included in the device identification.
Mode 2
Optionally, in 210, the determining, by the terminal device, the first sub identifier and the second sub identifier based on the device identifier of the terminal device includes: the terminal equipment determines the first sub-identification according to the equipment identification and the first compression function, and determines the second sub-identification according to the equipment identification and the second compression function.
The first compression function may be, for example, a first Hash (Hash) function, and the second compression function may be, for example, a second Hash function.
Therefore, in this embodiment, the device identifier is compressed by the first compression function and the second compression function, so that different sub identifiers, that is, the first sub identifier and the second sub identifier, can be obtained.
It should be understood that the first sub-identifier obtained from the device identifier and the first compression function may be different from or the same as the device identifier. And when the first sub-identifier is the same as the original equipment identifier of the terminal equipment, the original equipment identifier is not compressed.
In 220, the terminal device determines, according to the first sub-identifier, time information for receiving a paging (paging) message of the terminal device, where the paging message carries the second sub-identifier.
The time information includes a Paging radio Frame (PF) for receiving the Paging message, or includes the PF and a Paging Occasion (PO) in the PF for receiving the Paging message.
The embodiment of the application provides two ways for determining the time information. Described separately below.
Mode 1
the System Frame Number (SFN) of the PF for receiving the paging message satisfies SFN mod T ═ T/N × (UE-ID) in each Discontinuous Reception (DRX) cycle of the terminal device1mod N), where T is the time length of each DRX cycle, UE-ID1For the first sub-identity, N is the number of PFs available to receive the paging message per DRX cycle.
Specifically, a PF is a specific radio frame or system frame, and the PF may include one or more POs. The terminal device may attempt to receive the paging message on a certain PO in the PF within its paging cycle (i.e., DRX cycle). A Physical Downlink Control Channel (PDCCH) scrambled and indicating the Paging message using a Paging Radio Network temporary Identity (P-RNTI) may be transmitted on the PO. When DRX is used, the terminal device only needs to detect 1 PO per DRX cycle (DRX cycle). That is, for each terminal device, only 1 subframe may be used to transmit a paging message in each DRX cycle, where PF is a system frame used to transmit the paging message, and PO is a subframe used to transmit the paging message in the PF.
in this embodiment, the terminal device may be able to change the terminal device according to SFN mod T ═ (T/N) × (UE-ID)1mod N) to determine the location of the PF, i.e., the SFN of the PF, for receiving its paging message. Wherein SFN is the system frame number, UE-ID of the PF1For the first sub-identity, T is the time length of the DRX cycle finally used by the terminal device, and N is the number of PFs available for receiving the paging message in each DRX cycle.
in SFN mod T ═ T/N (UE-ID)1mod N), where T/N corresponds to dividing each DRX cycle T into N parts, each part including T/N radio frames, where PF is the first radio frame in the T/N radio frames. Thus, N may be considered as the number of PFs available to receive the paging message per DRX cycle. N may be determined by N ═ min (T, nB), where nB may be configured by a System Information Block (SIB), which may be equal to 4T, 2T, T, T/2, T/4, T/8, and so on, for example.
UE-ID1mod N indicates that the terminal equipment selects the second UE-ID in the N shares1mod N shares (UE ID mod N is more than or equal to 0 and less than N), and it can be seen that the terminal equipment selects which of the N shares is identified by the first sub-identifier UE-ID1And (6) determining. UE-ID1For example, the UE-ID may be obtained by using any one of the two manners in the foregoing 210 based on the device identification UE-ID of the terminal device, and the device identification UE-ID of the terminal device may be determined by an International Mobile Subscriber Identity (IMSI) of the terminal device, for example, the UE ID is IMSI mod 1204. The terminal equipment selects the UE-ID in the N shares1mod N shares, the second UE-ID is used1mod N, where the system frame number SFN of the PF may be (T/N) × (UE-ID) according to SFN mod T1mod N).
Mode 2
For receiving in each DRX period of the terminal deviceThe SFN of the PF of the paging message is: SFN (UE-ID)1) mod P, where UE-ID1For the first sub-identity, P is the number of radio frames included in each DRX cycle.
In this embodiment, the terminal device directly identifies the UE-ID according to the first sub-identifier1And the number P of wireless frames included in each DRX period, and determining the position of the PF, namely the SFN of the PF.
After determining the PF for receiving its paging message, the terminal device may further determine the PO for receiving the paging message in the PF.
Alternatively, the index of the PO for receiving the paging message in the PF may be represented by i _ s, whereWherein, the UE-ID1For the first sub-identity, N is the number of PFs available for receiving the paging message per DRX cycle, Ns is the number of POs included in the PF,to round down.
In 230, the terminal device receives the paging message according to the time information.
Therefore, the terminal device generates two sub-identifiers, namely a first sub-identifier and a second sub-identifier, based on the device identifier of the terminal device, and the first sub-identifier of the two sub-identifiers is used for determining the transmission time of the paging message carrying the second sub-identifier, so that the network device can effectively page the terminal device based on the second sub-identifier without causing large resource overhead, and even if the compressed second sub-identifiers of different terminal devices are the same, the terminal device can effectively identify the paging message of the terminal device according to the transmission time corresponding to the first sub-identifier of the terminal device, thereby determining whether the terminal device is paged by the network device, and reducing error paging.

In 320, the network device determines, according to the first sub-identifier, time information for sending a paging message, where the paging message carries the second sub-identifier, and the time information includes a paging radio frame (PF) used for sending the paging message, or includes the PF and a paging time PO in the PF used for sending the paging message.
In 330, the network device sends the paging message to the terminal device according to the time information.
Therefore, the network device generates two sub-identifiers, namely a first sub-identifier and a second sub-identifier, based on the device identifier of the terminal device, and determines the transmission time for sending the paging message carrying the second sub-identifier according to the first sub-identifier, so that the network device can effectively page the terminal device based on the second sub-identifier without causing large resource overhead, and even if the compressed second sub-identifiers of different terminal devices are the same, the terminal device can effectively identify the paging message thereof according to the transmission time corresponding to the first sub-identifier, thereby determining whether the terminal device pages the paging message.
Optionally, the device flag includes N bit values, where determining, by the network device according to the first sub-identifier, time information for sending a paging message includes: the network device determines M bit values of the N bit values as the first sub-identity and determines the remaining N-M bit values of the N bit values except the M bit values as the second sub-identity, wherein N, M is a positive integer and M < N.
Optionally, the M bit values are first M bit values of the N bit values, and the N-M bit values are last N-M bit values of the N bit values.
Optionally, the determining, by the network device, time information for sending a paging message according to the first sub-identifier includes: and the network equipment determines the first sub-identifier according to a first compression function and determines the second sub-identifier according to a second compression function.
Optionally, the first compression function is a first Hash function, and/or the second compression function is a second Hash function.
Optionally, the first sub-identifier is the same as the device identifier of the terminal device.
