Network side devices, etc.

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 configured to provide communication services for the terminal device 20 and access the core network. The terminal device 20 can access the network by searching for synchronization signals, broadcast signals, and 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 by a cellular link between the terminal device 20 and the network device 10.

The network in the embodiment of the present application may refer to a Public Land Mobile Network (PLMN) or a Device to Device (D2D) network or a machine. For a Machine to Machine/Man (M2M) network or other network, FIG. 1 is only a simplified schematic diagram of an example, and other terminal devices may also be included in the network, which are not shown in FIG.

When the downlink data of the terminal device arrives, the network device may establish a signaling connection of the terminal device to the network device by paging to the terminal device, thereby performing transmission of the downlink data.

A paging message of up to 16 terminal devices can be carried in a PDSCH channel. The paging messages of these terminal devices form a paging record list, and the terminal device reads each paging record in the paging record list. (Paging Record), each paging record includes a device identifier (UE-IDentity, UE-ID) of the paged terminal device. If a terminal device finds that its UE-ID is consistent with a certain UE-ID in a paging record list, it can judge that it is paged by the network device.

Since the paging messages of the multiple terminal devices are transmitted in one PDSCH, and the network device does not know the channel quality of the idle terminal device, the network device generally adopts a conservative modulation and coding manner when sending the paging message to the terminal. (Modulation and Coding Scheme, MCS), lower code rate or larger scheduling bandwidth to ensure that the terminal device at the cell edge can receive the paging message.

In a 5G system, the transmission of paging messages requires beam scanning to cover all downlink beams. When paging is performed by using beam scanning, paging messages need to be repeatedly sent in all beam directions, which brings 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 more than 10 bits. However, the problem that the UE-ID may cause after compression is that two new UE-IDs obtained by separately compressing two different UE-IDs may be the same, so that the network device sends a page to one of the terminal devices. In the case of a message, both terminal devices are paged, resulting in a false paging problem.

The embodiment of the present application proposes to generate two sub-identities, that is, a first sub-identity and a second sub-identity, based on the device identifier of the terminal device, and the first sub-identity of the two sub-identities is used to determine the transmission of the paging message carrying the second sub-identity. At a time, the network device can effectively page the terminal device based on the second sub-identity without causing a large resource overhead, and even if the compressed second sub-identities of the different terminal devices are the same, the terminal device can According to the transmission moment corresponding to the first sub-identity, the paging message is effectively identified, thereby determining whether to be paged by the network device, and the false paging is reduced.

FIG. 2 is a schematic flowchart of a paging method according to an embodiment of the present application. The method shown in Figure 2 can It is executed by a terminal device, which may be, for example, the terminal device 20 shown in FIG. As shown in FIG. 2, the paging method includes:

In 210, the terminal device determines the first sub-identity and the second sub-identity based on the device identifier of the terminal device.

The embodiment of the present application provides two ways to obtain the first sub-identity and the second sub-identity. Described separately below.

Mode 1

Optionally, the device identifier of the terminal device includes N bit values, where, in 210, the terminal device determines the first sub-identity and the second sub-identity based on the device identifier of the terminal device, including: the terminal device: The M bit values in the bit value are determined as the first sub-identity, and the remaining NM bit values other than the M bit values among the N bit values are determined as the second sub-identification, where N, M Is a positive integer and M < N.

Optionally, the M bit values are the first M bit values of the N bit values, and the N-M bit values are the last N-M bit values of the N bit values.

For example, the device identifier UE-ID of the terminal device is composed of N bit values, and if N=40, M=30, the first sub-identity UE-ID ₁ obtained by intercepting the UE-ID may be high. The 30-bit value, the second sub-identity UE-ID ₂ may be the remaining 10-bit value.

For another example, assuming N=40, M=10, then the first sub-identity may be a high-order 10-bit value, and the second sub-identity may be the remaining 30-bit value.

Therefore, in this embodiment, the bit values included in the device identifier are intercepted, so that different sub-identities, that is, the first sub-identity and the second sub-identity can be acquired.

Mode 2

Optionally, in 210, the determining, by the terminal device, the first sub-identity and the second sub-identification based on the device identifier of the terminal device, including: determining, by the terminal device, the first sub-identification according to the device identifier and the first compression function, and according to The device identification and the second compression function determine the second sub-identification.

The first compression function may be, for example, a first hash function, and the second compression function may be, for example, a second hash function.

Therefore, in this embodiment, the device identifier is separately compressed by the first compression function and the second compression function, so that different sub-identities, that is, the first sub-identity and the second sub-identification can be obtained.

It should be understood that the first sub-identification obtained according to the device identifier and the first compression function may be different from the device identifier or may be the same as the device identifier. When the first sub-identity and the original device of the terminal device When the backup ID is the same, it is equivalent to not compressing the original device ID.

In 220, the terminal device determines, according to the first sub-identity, time information for receiving a paging message of the terminal device, where the paging message carries the second sub-identity.

The time information includes a paging radio frame (PF) for receiving the paging message, or includes the PF and a paging moment for receiving the paging message in the PF (Paging Occasion, PO) ).

The embodiment of the present application provides two ways to determine 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) in each discontinuous reception (DRX) period of the terminal device. × (UE-ID ₁ mod N), where T is the length of time of each DRX cycle, UE-ID _{1 is} the first sub-identity, and N is the PF available for receiving the paging message in each DRX cycle. Quantity.

Specifically, the 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 a paging message on a certain PO in the PF within its paging cycle (ie, DRX cycle). A physical downlink control channel (PDCCH) that is scrambled by the Paging Radio Network Tempory Identity (P-RNTI) and indicates the paging message may be transmitted on the PO. When DRX is used, the terminal device only needs to detect 1 PO per DRX cycle. That is to say, for each terminal device, only one subframe in each DRX cycle can be used to send a paging message, PF is a system frame for transmitting the paging message, and PO is used in the PF. The subframe in which the paging message is sent.

In this embodiment, the terminal device may determine the location of the PF for receiving its paging message, ie, the SFN of the PF, according to SFN mod T = (T/N) x (UE-ID ₁ mod N). The SFN is the system frame number of the PF, the UE-ID _{1 is} the first sub-identity, T is the length of the DRX cycle that the terminal device finally uses, and N is used to receive the paging message in each DRX cycle. The number of PFs.

In SFN mod T=(T/N)×(UE-ID ₁ mod N), T/N is equivalent to dividing each DRX period T into N shares, each of which includes T/N radio frames, where PF The first radio frame in the T/N radio frames. Thus, N can be considered to be the number of PFs available to receive the paging message in each DRX cycle. N can be determined by N=min(T, nB), where nB can be configured through a System Information Block (SIB), for example, can be equal to 4T, 2T, T, T/2, T/4, T /8 and so on.

The UE-ID ₁ mod N indicates that the terminal device selects the UE-ID ₁ mod N share (0 ≤ UE ID mod N < N) of the N shares, and it can be seen that the terminal device selects which of the N shares, It is determined by the first sub-identity UE-ID ₁ . The UE-ID ₁ may be, for example, a device identification UE-ID based on the terminal device and obtained by using any one of the two methods 210, and the device identifier UE-ID of the terminal device may be an international mobile user of the terminal device. An International Mobile Subscriber Identity (IMSI) is determined, for example, UE ID = IMSI mod 1204. The terminal device selects the UE-ID ₁ mod N share in the N shares, and uses the PF included in the UE-ID ₁ mod N share. At this time, the system frame number SFN of the PF may be based on SFN mod T= (T/N) × (UE-ID ₁ mod N) to determine.

Mode 2

The SFN of the PF for receiving the paging message is: SFN=(UE-ID ₁ ) mod P in each DRX period of the terminal device, where UE-ID _{1 is} the first sub-identity, and P is the The number of radio frames included in each DRX cycle.

In this embodiment, the terminal device directly determines the location of the PF, that is, the SFN of the PF, according to the first sub-identity UE-ID ₁ and the number P of radio frames included in each DRX cycle.

After determining the PF for receiving the paging message, the terminal device may further determine the PO in the PF for receiving the paging message.

Optionally, an index of the PO in the PF for receiving the paging message may be represented by i_s, where

The UE-ID _{1 is} the first sub-identity, where N is the number of PFs that can be used to receive the paging message in each DRX cycle, and Ns is the number of POs included in the PF.

Rounded down.

In 230, the terminal device receives the paging message according to the time information.

Therefore, the terminal device generates two sub-identities, that is, the first sub-identity and the second sub-identity, based on the device identifier, and the first sub-identity of the two sub-identities is used to determine a transmission moment of the paging message carrying the second sub-identification, thereby The network device can effectively page the terminal device based on the second sub-identity without causing a large resource overhead, and even if the compressed second sub-identities of different terminal devices are the same, the terminal device can be configured according to the A sub-identification corresponds to the transmission moment, effectively identifying its own paging message, thereby determining whether it is paged by the network device, and reducing false paging.
