Therefore, 5G technology is expected to better support various mobile Internet services and bring better user experience. In order to realize the above-mentioned technical advantages, the development and realization of 5G products have also brought huge challenges. Specifically for 5G terminals, it supports transmission bandwidths of hundreds of MHz (megahertz), supports peak rates of up to tens of Gbps (gigabits), and supports transmission delays at the ms (millisecond) level. In addition, 5G terminals are also required to have strong software and hardware capabilities, such as large-bandwidth radio frequency devices (such as PA (Power Amplifier, power amplifier)), filters, high-speed baseband processors, etc., which bring huge power consumption to the terminal.

Detailed ways

The technical solutions in the embodiments of the present application will be described below in conjunction with the drawings in the embodiments of the present application.

The technical solutions of the embodiments of this application can be applied to various communication systems, such as: Global System of Mobile Communication (GSM) system, Code Division Multiple Access (CDMA) system, and Wideband Code Division Multiple Access (Wideband Code Division Multiple Access, WCDMA) system, General Packet Radio Service (GPRS), Long Term Evolution (LTE) system, Advanced Long Term Evolution (LTE-A) system , New Radio (NR) system, evolution system of NR system, LTE (LTE-based access to unlicensed spectrum, LTE-U) system on unlicensed spectrum, NR (NR-based access to unlicensed spectrum) unlicensed spectrum, NR-U) system, universal mobile telecommunication system (UMTS), wireless local area network (Wireless Local Area Networks, WLAN), wireless fidelity (Wireless Fidelity, WiFi), next-generation communications (5th-Generation) , 5G) system or other communication systems, etc.

Generally speaking, traditional communication systems support a limited number of connections and are easy to implement. However, with the development of communication technology, mobile communication systems will not only support traditional communication, but also support, for example, Device to Device (Device to Device, D2D) communication, machine to machine (Machine to Machine, M2M) communication, machine type communication (MTC), and vehicle to vehicle (V2V) communication, etc. The embodiments of this application can also be applied to these communications system.

Optionally, the communication system in the embodiments of the present application can be applied to a carrier aggregation (Carrier Aggregation, CA) scenario, can also be applied to a dual connectivity (DC) scenario, and can also be applied to a standalone (SA) deployment. Network scene.

The embodiment of the application does not limit the applied frequency spectrum. For example, the embodiments of this application can be applied to licensed spectrum or unlicensed spectrum.

The embodiments of this application describe various embodiments in combination with network equipment and terminal equipment. The terminal equipment may also include user equipment (UE), access terminal, user unit, user station, mobile station, mobile station, and remote station. , Remote terminal, mobile device, user terminal, terminal, wireless communication device, user agent or user device, etc. The terminal device can be a station (STAION, ST) in the WLAN, a cellular phone, a cordless phone, a Session Initiation Protocol (SIP) phone, a wireless local loop (Wireless Local Loop, WLL) station, and personal digital processing (Personal Digital Assistant, PDA) devices, handheld devices with wireless communication capabilities, computing devices or other processing devices connected to wireless modems, vehicle-mounted devices, wearable devices, and next-generation communication systems, such as terminal devices in the NR network or Terminal equipment in the public land mobile network (PLMN) network that will evolve in the future.

As an example and not a limitation, in the embodiment of the present application, the terminal device may also be a wearable device. Wearable devices can also be called wearable smart devices. It is a general term for using wearable technology to intelligently design everyday wear and develop wearable devices, such as glasses, gloves, watches, clothing and shoes. A wearable device is a portable device that is directly worn on the body or integrated into the user's clothes or accessories. Wearable devices are not only a kind of hardware device, but also realize powerful functions through software support, data interaction, and cloud interaction. In a broad sense, wearable smart devices include full-featured, large-sized, complete or partial functions that can be achieved without relying on smart phones, such as smart watches or smart glasses, and only focus on a certain type of application function, and need to cooperate with other devices such as smart phones. Use, such as all kinds of smart bracelets and smart jewelry for physical sign monitoring.

A network device can be a device used to communicate with mobile devices. The network device can be an access point (AP) in WLAN, a base station (BTS) in GSM or CDMA, or a device in WCDMA. A base station (NodeB, NB), can also be an Evolutional Node B (eNB or eNodeB) in LTE, or a relay station or access point, or a vehicle-mounted device, a wearable device, and a network device (gNB) in the NR network Or network equipment in the PLMN network that will evolve in the future.

In the embodiment of the present application, the network equipment provides services for the cell, and the terminal equipment communicates with the network equipment through the transmission resources (for example, frequency domain resources, or spectrum resources) used by the cell, and the cell may be a network equipment (for example, The cell corresponding to the base station. The cell can belong to a macro base station or a base station corresponding to a small cell. The small cell here can include: Metro cell, Micro cell, Pico Cells, Femto cells, etc. These small cells have the characteristics of small coverage and low transmit power, and are suitable for providing high-rate data transmission services.

Figure 1 exemplarily shows one network device 110 and two terminal devices 120. Optionally, the wireless communication system 100 may include multiple network devices 110, and the coverage of each network device 110 may include other numbers. The terminal device 120 is not limited in this embodiment of the application.

Optionally, the wireless communication system 100 may also include other network entities such as mobility management entities (Mobility Management Entity, MME), access and mobility management functions (Access and Mobility Management Function, AMF), etc. This is not limited.

It should be understood that the terms "system" and "network" in this article are often used interchangeably in this article. The term "and/or" in this article is only an association relationship describing the associated objects, which means that there can be three relationships, for example, A and/or B, which can mean: A alone exists, A and B exist at the same time, exist alone B these three situations. In addition, the character "/" in this text generally indicates that the associated objects before and after are in an "or" relationship.

The communication module of the 5G terminal has high power consumption, and the current mobile communication terminal, in other devices such as touch screen, fingerprint recognition module, image module, etc., are developing towards low power consumption. With the reduction of the power consumption of these modules, the power consumption of the communication module accounts for a relatively increase in the power consumption of the entire terminal.

Related technologies include energy-saving mechanisms such as wake-up mechanism, cross-slot scheduling, and sleep operation of Scell (Secondary cell, secondary cell), which are used for terminal energy saving. The above is mainly aimed at the energy-saving optimization of the terminal working in the RRC (Radio Resource Control) connected state. There are also some energy-saving optimizations for terminals in RRC idle and RRC inactive states.

In some application scenarios, a terminal in the form of a multi-SIM (Subscriber Identity Module) card terminal appears. In order to meet people's diverse communication needs, terminal manufacturers provide multi-SIM terminals.

For example, multi-SIM terminals include dual-card dual-standby mobile phones. Dual-SIM dual-standby mobile phone refers to a mobile phone that can insert two SIM cards at the same time, and both of them are in the standby state. Dual card dual standby may include dual card dual standby of the same network standard, for example: dual card dual standby for GSM network, dual card dual standby for CDMA network, or dual card dual standby for PHS network.

For another example, multi-SIM terminals include dual-network dual-standby mobile phones. The dual-network dual-standby mobile phone can be inserted into two number cards of different networks at the same time, and they can be turned on at the same time. Users can dial, receive and send and receive text messages at will without switching networks.

Dual USIM (Universal Subscriber Identity Module) card mobile phones are a major development trend. The mobile phone capability may not support pure dual-pass (Dual UL/DL, dual-transmit and dual-receive). Dual-transmit and dual-receive may mean that the UE simultaneously sends uplink data and receives downlink data on two networks through two SIM cards. Most mobile phones support Single UL/DL (single transmission and single receiving) or Single UL/Dual DL (single transmission and dual receiving). In this case, the UE can only perform data receiving and sending services on one SIM card at the same time.

In an exemplary scenario of 5G, dual-card dual-standby or dual-network dual-standby may include two USIM cards, one of which can reside in an LTE cell, the other in an NR cell, or both USIM cards reside in NR cell. The two USIM cards can belong to the same operator or different operators.

In other exemplary scenarios, the new smart wearable device also has communication functions similar to mobile phones, such as sending text messages, answering calls, and even video chatting. People may carry smart phones while using smart wearable devices, so these two types of terminals are usually related. Smart wearable devices such as smart watches, in addition to providing time display, can also provide health monitoring (such as heart rate, blood pressure), exercise counting and other functions.

In scenarios such as multi-SIM terminals and smart wearable devices, multiple user terminals may have relevance characteristics in terms of use time or used location and space.

NR paging message transmission is initiated by the network to the UE in the idle state, inactive state or connected state. Paging includes CN (Core Network, core network) initial paging messages and RAN (Radio Access Network, radio access network) initial paging messages.

CN initial paging: Initiate paging within the scope of the registered TA list. Notify the UE to receive a paging request. In this case, the UE belongs to the called party and can push data to the UE.

RAN initial paging: A paging message is initiated within the RAN range. Notify the UE to receive a paging request. Data can be pushed to the UE.

gNB triggers paging (for example: SI (System Information) change notification): initiates paging within the cell; notifies system message updates and notifies UE to receive ETWS (Earthquake and Tsunami Warning System, earthquake and tsunami warning system) and other information . At this time, the DCI (Downlink Control Information) carries the system message change indication and the PWS (Public Warning System, public warning system) notification indication.

Paging messages can be carried on PDSCH (Physical Downlink Shared Channel); transmission is scheduled through PDCCH (Physical Downlink Control Channel). P-RNTI (Paging RNTI, Paging RNTI (Radio Network Temporary Identifier)) has a fixed value of FFFE (hexadecimal) and is used to scramble and schedule the DCI of the PDSCH carrying the paging message. When there is a paging, the network side will send a PDCCH grant (authorization) on the PDCCH at the calculated paging occasion. If the UE monitors the P-RNTI on the PDCCH at the paging occasion, it will receive the paging message on the designated time-frequency resource.

Exemplarily, the paging message may include:

The identity of the paged UE: When the terminal is in the RRC IDLE (idle) state, the CN initial paging is S-TMSI (Serving-Temporary Mobile Subscriber Identity). As shown in Figure 2, AMF is based on NGAP (NGAP). Application Protocol, NG interface application protocol) sends a paging message including S-TMSI to the gNB. When the terminal is in the RRC INACTIVE (inactive) state, the RAN initial paging is I-RNTI (Inactive-RNTI, inactive RNTI), as shown in Figure 3. It does not support IMSI (International Mobile Subscriber Identity)/SUPI (SUbscription Permanent Identifier)/SUCI ((SUbscription Concealed Identifier) for paging UEs. Up to 32 pages can be simultaneously paged. UEs.

Access type that triggers paging: 3GPP or non-3GPP. The instruction needs to be delivered to the higher layer to indicate the access network technology to which a PDU (Packet Data Unit) session belongs.

Referring to Figures 2 and 3, in different RRC states, there are different requirements for receiving paging messages. See Table 1 for specific examples.

Table 1

In NR, the characteristics of paging frame and paging occasion are as follows:

The UE receives the paging message at its own paging occasion in the RRC_IDLE and RRC_INACTIVE states. The UE does not need to monitor the PDCCH all the time, but only needs to monitor at the paging occasion, so as to achieve the purpose of power saving on the UE side. The calculation of the paging occasion is based on the DRX cycle, and the size of the DRX cycle determines the balance between UE power saving and access delay. There are three DRX used for the UE to calculate the paging occasion:

Cell default DRX cycle (cycle): The cell system broadcasts the cell-level DRX cycle.

UE specific DRX cycle: The DRX cycle independently determined by the UE can be sent to the CN through NAS messages, and the CN sends to the gNB during paging.

RAN DRX: When the network side decides to let the UE enter INACTIVE, it is configured to the UE through the RRC Release message.

The UE and the network side can use the minimum principle to select the DRX cycle for calculating the paging occasion. For RRC_IDLE UE, the smallest DRX cycle is used among the cell-level DRX cycle (Cell default DRX cycle) and the UE-specific DRX cycle (UE specific DRX cycle) independently determined by the UE. For RRC_INACTIVE UE, the smallest DRX cycle among Cell default DRX cycle, UE-specific DRX cycle, and RAN DRX cycle is used.

In NR, it is used to support beam sweeping, and the paging occasion is not fixed to one subframe like LTE. The UE assumes that paging messages with the same content are transmitted in parallel on all beams, and the beam on which the UE receives the paging message depends on the UE implementation. For example, before receiving the paging message, the UE measures the downlink reference signal to determine which beam has the strongest received signal strength. The paging message is received in the beam with the strongest received signal.

A PO (Paging Occasion, paging occasion) may include a set of PDCCH monitoring occasions (monitoring occasion). The length of the PO is determined by the actual number of transmissions of SSB (Synchronization Signaland PBCH block) and SCS (Sub Carrier Spacing). PO refers to the timing of scheduling the DCI of the PDSCH carrying the paging message, rather than the timing of transmitting the paging message.

The CORESET (Control Resource Set) of the DCI that schedules the PDSCH carrying the paging message can be the same as the CORESET of the RMSI (Remaining Minimum System Information), or the CORESET of paging can be independently configured.

In a DRX cycle, a UE only needs to monitor one paging occasion. The paging frame includes a radio frame, and the radio frame includes the starting position of one or more paging occasions.

PF is obtained by the following formula: (SFN+PF_offset) mod T = (T div N) * (UE_ID mod N)

PO is obtained by the following formula: i_s=floor(UE_ID/N)mod Ns

Among them, mod represents modulo operation.

The parameter configuration (configured in SIB1 (System Information Block)) is as follows:

T: The DRX cycle (default DRX, RAN DRX, UE-specific DRX) obtained according to the above minimum principle;

N: the number of paging frames in the DRX cycle;

Ns: the number of PO in PF;

PF_offset: Determine the offset of PF;

UE_ID: 5G-S-TMSI mod 1024;

For the common search space of paging and RMSI, Ns is equal to 1 or 2. Ns=1, which means there is only one PO in the PF. Ns=2, which means that PO is in the first half frame of PF (i_s=0) or in the second half frame of PF (i_s=1).

For the case of configuring an independent paging search space, the UE monitors the (i_s+1)th PO. PO includes S consecutive PDCCH monitoring occasions, and S is the number of actually transmitted SSBs. The Kth PDCCH monitoring occurrence in the PO corresponds to the Kth SSB. In order to make the distribution of paging occasions in the paging frame PF balanced, the first PDCCH monitoring occasion of the PO (firstPDCCH-MonitoringOccasionOfPO) is introduced. If firstPDCCH-MonitoringOccasionOfPO is configured, it indicates the starting PDCCH monitoring occasion position of each PO in the PF. If firstPDCCH-MonitoringOccasionOfPO is not configured, the starting PDCCH monitoring occasion position of each PO in PF is i_s*S. The PDCCH monitoring occasions in a PF are numbered consecutively starting from 0.

For a multi-SIM card terminal scenario, the terminal needs to receive paging messages from multiple user terminals corresponding to the multiple SIM cards. Each user terminal of the plurality of user terminals determines the location of the PO according to the foregoing method of determining the PO used to receive the paging message. Since the user terminal identities such as UE IDs of multiple user terminals are different, the positions of the calculated POs may be different. In addition, the period of receiving paging messages for each user terminal may also be different.

Therefore, for multiple user terminals corresponding to multiple SIM cards in the multi-card terminal, the time for each user terminal to receive the paging message may also be different. Since the terminal is in the IDLE or RRC INACTIVE state, the main operation is to receive paging messages. For a multi-card terminal, each SIM card has a potentially different time position for receiving paging messages from other SIM cards. Therefore, in each paging cycle, the multi-card terminal may need to wake up multiple times to receive paging messages. This will increase the power consumption of the terminal in the IDLE or RRC INACTIVE state.

FIG. 4 is a schematic flowchart of a method 200 for determining a paging time position according to an embodiment of the present application. This method can optionally be applied to the system shown in FIG. 1, but is not limited to this. The method includes at least part of the following content.

S210. The first user terminal determines paging parameters.

S220. The first user terminal determines a paging time position based on the paging parameter.

Optionally, in this embodiment of the present application, determining the paging parameter by the first user terminal includes: the first user terminal determines the paging parameter of the first user terminal based on the paging parameter of the second user terminal. Then, the first user terminal determines the paging time position based on its own paging parameters, such as paging frame and paging occasion. The first user terminal may receive the paging message at the paging time position. The paging time position of the first user terminal and the paging time position of the first user terminal may be the same or partly the same. In the embodiment of the present application, the first user terminal and the second user terminal may be associated user terminals.

In some scenarios, multiple user terminals may be associated. Examples are as follows:

In scenario 1, multiple user terminals are located in the same communication device, such as the terminal device in FIG. 1.

For example, a mobile phone can include two SIM cards, and each SIM card can serve as a user terminal. The two user terminals included in the mobile phone are related.

Scenario 2: Multiple user terminals are not located in the same communication device, but they can be determined to have an association relationship through some information.

In one case, multiple user terminals can be connected through short-distance communication. For example, a mobile phone may include one user terminal, and a wearable device such as a phone watch may include another user terminal. The two are not in the same communication device, but can be connected through short-distance communication such as Bluetooth. The user terminal included in the mobile phone is associated with the user terminal included in the phone watch.

In another case, the channel conditions of multiple user terminals are correlated. For example, a certain cell phone and bracelet used by the same person may have similar channel conditions. The location of a mobile phone and bracelet used by the same person are generally close, and the channel quality and signal strength of the two may be similar. On the network side, for example, the base station can determine whether the mobile phone and the bracelet are related according to their channel status. If the base station obtains that the channel conditions of the mobile phone and the bracelet are similar, it can determine the association between the mobile phone and the bracelet. For example, after the base station receives measurement results of channel conditions such as channel quality and signal strength reported by the terminal side, it can determine whether the channel conditions of multiple user terminals are similar based on these measurement results. Then, the base station can determine whether the mobile phone and the bracelet have similar channel conditions to determine whether they are related.

In another case, the movement tracks of multiple user terminals are related. On the network side, it can be determined whether the mobile phone and the bracelet are related according to their movement trajectories. For example, a certain cell phone and bracelet used by the same person may access the same cell and leave from a certain cell at the same time. If the base station detects that the mobile phone and the bracelet have similar movement trajectories, it can obtain the associated information of the mobile phone and the bracelet.

The user terminal can report the associated information to CN (Core Network) equipment. The CN device can record or save the associated information received. When some processing such as paging is needed, the CN device can send the saved association information to the base station. Correspondingly, the base station can receive the association information from the CN device. For example, the CN device needs to send a paging message to UE1 and UE2. The CN device may send the association information of UE1 and UE2 to the base station, and the base station uses the association information to page UE1 and/or UE2.

When the network device determines that multiple user terminals are associated, it may send association information to these user terminals.

Multiple associated user terminals can determine paging frames and paging occasions based on the same paging parameters. The paging frames and paging occasions of these user terminals obtained in this way may be the same. In other words, these user terminals can receive paging messages in the same paging frame and paging occasion.

Multiple associated user terminals may also determine paging frames and paging occasions based on paging parameters having an integer multiple relationship. The paging frames and paging occasions of these user terminals obtained in this way may be partly the same. In other words, these user terminals can receive paging messages in part of the same paging frame and paging occasion.

Therefore, if multiple user terminals are in the same communication device, the communication device can wake up from the DRX sleep state at the same or part of the same paging time position, and perform the necessary AGC (Automatic Gain Control), time-frequency Synchronize operation, and further receive paging messages of these user terminals at the paging time position, so as to reduce the number of times the communication device wakes up and achieve the effect of energy saving.

Optionally, in this embodiment of the present application, the first user terminal determines the paging parameters of the first user terminal based on the paging parameters of the second user terminal, including: the first user terminal is autonomously based on the second user terminal The determined discontinuous reception DRX cycle (UE specific DRX cycle) determines the DRX cycle independently determined by the first user terminal.

Optionally, in the embodiment of the present application, the DRX cycle autonomously determined by the first user terminal is the same as or has an integer multiple relationship with the DRX cycle autonomously determined by the second user terminal.

Multiple associated user terminals can coordinate the autonomously determined DRX cycle, so that the associated multiple user terminals autonomously determine the same DRX cycle or have an integer multiple relationship. For example, both the first user terminal and the second user terminal use the UE-specific DRX cycle of the second user terminal. For another example, both the first user terminal and the second user terminal use the UE-specific DRX cycle of the first user terminal. For another example, the UE-specific DRX cycle of the first user terminal has an integer multiple relationship with the UE-specific DRX cycle of the second user terminal.

Exemplarily, UE1 can refer to the UE-specific DRX cycle of UE2 to determine its own UE-specific DRX cycle. For example, the UE-specific DRX cycle of UE1 is equal to the UE-specific DRX cycle of UE2. For another example, the UE-specific DRX cycle of UE1 is an integer multiple of the UE-specific DRX cycle of UE2. For another example, the UE-specific DRX cycle of UE2 is an integer multiple of the UE-specific DRX cycle of UE1.

For a UE in an RRC idle state, the smallest DRX cycle among the cell-level DRX (Cell default DRX) cycle and the UE-specific DRX cycle independently determined by the UE can be used as the paging cycle. If the UE-specific DRX cycles of UE1 and UE2 in the RRC idle state are the same, the paging cycles of UE1 and UE2 are also the same. If the UE-specific DRX cycle of UE1 and UE2 in the RRC idle state has an integer multiple relationship, the paging cycle of UE1 and UE2 also has an integer multiple relationship.

For UEs in the RRC inactive state, the cell-level DRX (Cell default DRX) cycle, the UE-specific DRX (UE specific DRX) cycle independently determined by the UE, and the smallest DRX cycle of the RAN (radio access network) DRX cycle can be used as the search Call cycle. If the UE-specific DRX cycles of UE1 and UE2 in the RRC inactive state are the same, the paging cycles of UE1 and UE2 are also the same. If the UE-specific DRX cycle of UE1 and UE2 in the RRC idle state has an integer multiple relationship, the paging cycle of UE1 and UE2 also has an integer multiple relationship.

In addition, the cell default DRX cycle is sent through a broadcast message, so the cell default DRX cycle is the same for all user terminals located in the same cell. If the user terminal reports the UE-specific DRX cycle, the DRX cycle reported by the user terminal of multiple SIM cards in a communication device such as a multi-card mobile phone can refer to the above example, and a certain amount of coordination is required. For example, the DRX cycles reported by user terminals of multiple SIM cards in the same communication device are the same or have an integer multiple relationship.

If the network equipment is configured with the RAN DRX cycle, the RAN DRX cycles configured for the user terminals of the multiple SIM cards in the multi-card mobile phone also need to be coordinated to ensure that the user terminals of the multiple SIM cards can determine the search. The call cycle is the same or has an integer multiple relationship. For example, the RAN DRX cycle configured by the network device for the user terminals of multiple SIM cards in the same communication device is the same or has an integer multiple relationship.

The foregoing multiple SIM cards located in the same communication device is only an exemplary scenario, and in other associated scenarios, a similar manner can also be used to coordinate the paging cycle. For example, a mobile phone is associated with a wearable device such as a bracelet, or multiple SIM cards are associated through a contract, and the paging cycles of these associated user terminals can be coordinated to be the same or have an integer multiple relationship.

Optionally, in this embodiment of the present application, the first user terminal determines the paging parameters of the first user terminal based on the paging parameters of the second user terminal, including: the first user terminal is based on the user of the second user terminal The terminal identifier determines the paging parameter of the first user terminal.

Optionally, in this embodiment of the present application, the paging parameter of the first user terminal is the user terminal identifier of the second user terminal.

Specifically, the user terminal may obtain the user terminal identifier of the associated user terminal, and then determine its own paging parameter based on the user terminal identifier of the associated user terminal. For example, UE1 and UE2 are associated user terminals. UE1 determines that its own UE ID used to calculate the paging time position is the same as the UE ID of UE2.

In addition, the first user terminal may also set its own user terminal identification used to calculate the paging time position to be the same as the user terminal identification part of the second user terminal. For example, UE1 uses the last x bits of the UE ID of UE2 (for example, x=6) as the user terminal identifier used to calculate the paging time position. For another example, UE1 combines its own UE ID and UE2's UE ID into a new UE ID, which is used to calculate the paging time positions of UE1 and UE2.

In the embodiment of the present application, multiple associated user terminals may determine the paging time position based on the same user terminal identifier. For example, both UE1 and UE2 determine the paging frame and paging occasion based on the UE ID of UE1. For another example, both UE1 and UE2 determine the paging frame and paging occasion based on the UE ID of UE2. For another example, both UE1 and UE2 determine the paging frame and paging occasion based on a certain common UE ID. The public UE ID may be a UE ID calculated or converted according to the UE ID of UE1 and/or UE2, or may be a randomly generated UE ID. In addition, other methods may also be used to determine the public UE ID.

Optionally, in the embodiment of the present application, the first user terminal determines the paging parameters of the first user terminal based on the paging parameters of the second user terminal, including: the first user terminal receives the configuration from the network device Information; the first user terminal determines the paging parameters of the first user terminal based on the configuration information.

Optionally, in this embodiment of the present application, the configuration information includes the user terminal identifier.

Optionally, in this embodiment of the present application, the user terminal identifier included in the configuration information is the user terminal identifier of the second user terminal or the public user terminal identifier.

Specifically, the network device may determine which paging parameters the user terminal uses to determine the paging time position. For example, the network device instructs multiple user terminals to use the same user terminal identifier to determine the paging time position through configuration information. In this case, the network device may separately send configuration information including the user terminal identifier to the multiple user terminals. The user terminal that receives the configuration information can substitute the same UE ID into the calculation formulas of PO and PF to calculate the respective PO and PF.

In the embodiment of the present application, the user terminal determines its own paging parameter based on the paging parameter of the associated user terminal, which can optimize the paging process and improve the paging efficiency.

Optionally, in the embodiment of the present application, the method further includes: the first user terminal receives a paging message at the determined paging time position; the first user terminal determines based on the user terminal identifier included in the paging message Whether you are paged.

Optionally, in the embodiment of the present application, if the user terminal identifier is included in the paging message as the user terminal identifier of the first user terminal, the first user terminal determines that it is paged.

Optionally, in the embodiment of the present application, if the paging message includes the user terminal identifier as the agreed user terminal identification, the first user terminal determines that it is paged; the agreed user terminal identification is the The user terminal identifier of the first user terminal, the user terminal identifier of the second user terminal, or the public user terminal identifier.

In some scenarios, multiple associated user terminals carry their respective user terminal identifiers in paging messages received at the same or part of the same paging time position. For example, UE1 and UE2 receive paging messages in the same PO and PF. If UE1 detects that the paging record list of the paging message includes the UE ID of UE1, it means that UE1 is paged. If UE2 detects that the paging record list of the paging message includes the UE ID of UE2, it means that UE2 is paged. For example, in a scenario where multiple user terminals are located in the same communication device, the communication device can use the same or part of the same paging time position to receive paging messages, reducing the number of times the communication device wakes up from the DRX sleep state, and realizes energy saving.

In other scenarios, such as business scenarios such as operators with multiple terminals on one number, multiple user terminals have an association relationship on the network side. For example, multiple user terminals are associated through a contract. In this scenario, usually, one user terminal is paged, and the other user terminal is also paged at the same time. The network equipment uses different paging resources for the paging of the two user terminals. In combination with the technical solution of this application, some coordination can also be done on this scenario. For example, first, the paging time positions of two user terminals are coordinated with reference to the above-mentioned method for determining the paging time position. Further, the paging messages of the two user terminals can be bound. For example, the two user terminals can be paged through an agreed user terminal identifier. The agreed user terminal identifier can be the UE ID of UE1, the UE ID of UE2, or the UE ID notified by the network, or the aforementioned UE ID used to determine the paging time position. In this way, the paging record list of the paging message sent by the network device may include the agreed UE ID. If UE1 detects that there is the agreed UE ID in the paging message, it can determine that it is paged. If UE2 detects that there is the agreed UE ID in the paging message, it can determine that it is paged. In addition, similar processing can also be performed in scenarios where multiple user terminals such as mobile phones and wearable devices are associated. In these scenarios, multiple associated user terminals can not only receive the same paging message at the same paging time position, but also use the same agreed UE ID, which can reduce the information that needs to be transmitted during the paging process and avoid using different paging. Paging resources page multiple associated user terminals, thereby saving channel resources.

Optionally, in this embodiment of the present application, the method further includes: the first user terminal reporting associated information, where the associated information includes information of a second user terminal associated with the first user terminal.

Among them, the associated information may include but is not limited to at least one of the following:

The user terminal identifier of the associated user terminal, such as UE ID, sTMSI (serving-Temporary Mobile Subscriber Identity, temporary mobile user identity);

The network standard supported by the associated user terminal, such as WCDMA, TD-SCDMA (Time Division-Synchronous Code Division Multiple Access, Time Division Synchronous Code Division Multiple Access), LTE, NR;

Subscription information of the associated user terminal. For example, if two SIM cards belong to the same operator, the reported subscription information may be the PLMN (Public Land Mobile Network, public land mobile network) of the operator.

Optionally, in the embodiment of the present application, in a scenario where multiple user terminals are located in the same communication device, the method further includes: the first user terminal obtains the associated information through the communication device, and the communication device is the first user terminal The communication device where the second user terminal is located.

Optionally, in this embodiment of the present application, obtaining the association information through a communication device includes: reading, through the communication device, information about the SIM of the user terminal associated with the first user terminal. For example, a mobile phone includes SIM card 1 and SIM card 2, and the information of SIM card 1 and SIM card 2 can be read through the mobile phone. Then, the user terminal corresponding to SIM card 1 or the user terminal corresponding to SIM card 2 can report the information of SIM card 1 and SIM card 2 to the network together.

Optionally, in the embodiment of the present application, when multiple user terminals are connected through short-range communication, the method further includes: the first user terminal obtains the associated information through short-range communication.

Optionally, in this embodiment of the present application, acquiring the associated information through short-range communication includes: acquiring SIM information of the user terminal associated with the first user terminal through short-range communication. For example, the mobile phone receives the information of the SIM card in the watch from the phone watch via Bluetooth.

Optionally, in this embodiment of the present application, the reporting of the associated information by the first user terminal includes: the first user terminal reporting the associated information during the registration process or the attachment process.

Optionally, in this embodiment of the present application, the method for reporting the associated information includes at least one of the following:

RRC signaling;

NAS (Non-Access Stratrum) signaling;

MAC (Medium Access Control) CE (Control Element).

In addition, the first user terminal may also report to the network whether there is a status associated with the second user terminal. For example, if the SIM card 1 and the SIM card 2 are in the same mobile phone, the SIM card 1 or the SIM card 2 can send the status that the two are associated to the network side. If a certain SIM card is taken out, SIM card 1 or SIM card 2 can send a state that the two are not associated to the network side. For another example, if the mobile phone and the phone watch are in a short-distance communication connection state, the mobile phone or the phone watch can send the state that the two are associated to the network side. If the short-distance communication connection between the two is disconnected, the mobile phone or the phone watch can send the status that the two are not associated to the network side.

In the embodiment of the present application, the user terminal reports information of the user terminal associated with the user terminal, which can reduce unnecessary power consumption and realize energy saving.

For example, when a network device determines that multiple user terminals are associated, it can use the same or an integer multiple of paging parameters to determine the paging time positions of these associated user terminals. The paging frames and paging occasions of these user terminals obtained in this way may be the same or partly the same. Then, the network device can send paging messages to these user terminals in the same or part of the same paging frame and paging occasion.

Optionally, in the embodiment of the present application, the paging message includes an agreed user terminal identification, and the agreed user terminal identification is the user terminal identification of the first user terminal and the user terminal identification of the second user terminal. User terminal ID or public user terminal ID.

In some scenarios, the network device may send paging messages to multiple associated user terminals at the same or part of the same paging time location. The paging record list of the paging message carries the user terminal identifiers of the associated user terminals. For example, a paging message sent by a network device to UE1 and UE2 at the determined PO and PF. If UE1 detects that the paging record list of the paging message includes the UE ID of UE1, it means that UE1 is paged. If UE2 detects that the paging record list of the paging message includes the UE ID of UE2, it means that UE2 is paged. For example, in a scenario where multiple user terminals are located on the same communication device, the network device can send paging messages to multiple user terminals in the communication device at the same or part of the same paging time position, reducing the communication device’s DRX dormancy The number of times the state wakes up to save energy.

In other scenarios, such as business scenarios such as operators with multiple terminals on one number, multiple user terminals have an association relationship on the network side. Generally, one user terminal is paged, and the other user terminal is also paged at the same time. In combination with the technical solution of this application, some coordination can also be done on this scenario. For example, first, the paging time positions of two user terminals are coordinated with reference to the above-mentioned method for determining the paging time position. Further, the paging messages of the two user terminals can be bound. For example, the two user terminals can be paged through an agreed user terminal identifier. The agreed user terminal identifier can be the UE ID of UE1, the UE ID of UE2, or the UE ID notified by the network, or the aforementioned UE ID used to determine the paging time position. In this way, the paging record list of the paging message sent by the network device may include the agreed UE ID. If UE1 detects that there is the agreed UE ID in the paging message, it can determine that it is paged. If UE2 detects that there is the agreed UE ID in the paging message, it can determine that it is paged. Similar processing can also be performed in scenarios where multiple user terminals such as mobile phones and wearable devices are associated. In these scenarios, the network device can also send the same paging message to multiple associated user terminals at the same paging time position, and use the same agreed UE ID, which can reduce the information that needs to be transmitted during the paging process. Avoid using different paging resources to page multiple associated user terminals, thereby saving channel resources.

The same terms in the method 300 executed by the network device in this embodiment and the method 200 described above have the same meaning, and the relevant explanations and examples of the method 200 described above can be referred to. For the sake of brevity, details are not described herein again.

Application example 1:

In a multi-card terminal scenario, there may be multiple user terminals in the same communication device. The network device can use a coordinated paging mode for multiple user terminals that have an association relationship, so that the multi-card terminals can receive paging messages at the same or part of the same time position. Therefore, the communication device can be prevented from operating multiple times during the process of receiving the paging message, thereby saving the power consumption of the communication device.

In this example, the way of coordinating paging time and location may include coordinating paging parameters such as paging cycle and UE ID. By coordinating the paging time position of the multi-user terminal in the multi-SIM card terminal, energy saving of the terminal is realized.

Multiple user terminals with an association relationship may determine the time position of receiving paging based on the same paging parameter or with a certain conversion relationship.

An example of the coordination process of the paging time position of multiple user terminals is as follows:

An example of multiple user terminals located in the same communication device is a multi-card mobile phone, such as a dual-card dual-standby mobile phone. Two SIM cards are embedded in one mobile phone device, and the two SIM cards are two user terminals. If it can be coordinated so that two user terminals receive paging messages at the same time and location, it is beneficial for the communication equipment to save power. In doing so, the communication device only needs to wake up from the DRX sleep state before the same or part of the same time position for receiving the paging message, perform necessary AGC, time-frequency synchronization operations, and further receive paging at the time position of the paging message. Call the news. In comparison, if the time positions of two SIM card user terminals receiving paging are not coordinated, the paging messages are received at different time positions. The communication device needs to wake up multiple times, perform multiple necessary AGC, time-frequency synchronization operations, and receive multiple paging messages at multiple different paging time positions. Obviously, coordinating the same or partly the same paging time position reduces the related operations of the communication device including multiple user equipments to receive the paging message, thereby conducive to the power saving of the communication device.

In order to coordinate the paging time receiving positions of the user terminals (hereinafter referred to as multiple SIM users) corresponding to the multiple SIM cards in the multi-card mobile phone, it is necessary to coordinate the relevant parameters used by the multiple SIM users to determine the paging time position.

Based on the paging mechanism, it can be known that the paging cycle T and the UE ID are two factors that affect the user terminal to determine the location of the PF and PO. The following examples illustrate the coordination process of the paging cycle of multiple SIM users and the UE ID.

1. Coordination of paging cycle

In order to make the paging time positions determined by multiple SIM users consistent or partially consistent in the communication device, the paging cycles of multiple SIM users may be the same, or the paging cycles of multiple SIM users may have an integer multiple relationship.

For example, for a UE in RRC_IDLE, the smallest DRX cycle of the Cell default DRX cycle and the UE specific DRX cycle (if the UE reports the UE specific DRX cycle) is used. For UE in RRC_INACTIVE, use Cell default DRX cycle, UE specific DRX (if the UE reports the UE specific DRX cycle) and RAN DRX cycle (if the network device is configured with the RAN DRX cycle), which is the smallest DRX. In this example, since paging adopts DRX transmission, the DRX cycle here can be used as the paging cycle.

In the above process of determining the cycle of the paging message of the user terminal, the cell default DRX cycle is sent through a broadcast message, so the cell default DRX cycle is the same for all user terminals located in the same cell. Therefore, if the user terminal reports the UE-specific DRX cycle, the DRX cycles reported by multiple SIM users in the multi-card mobile phone need to be coordinated. For example, the UE-specific DRX cycle reported by multiple SIM card users in the same communication device is the same. For another example, in the same communication device, the DRX cycle reported by one SIM user is an integer multiple of the DRX cycle reported by another SIM user.

In addition, if the network equipment is configured with a RAN DRX cycle, the RAN DRX cycles configured for multiple SIM users in a multi-card mobile phone also need to be coordinated. For example, the RAN DRX cycle configured by the network device for multiple SIM users in the same communication device is the same. For another example, the RAN DRX cycle configured by the network device for a SIM user in the same communication device is an integer multiple of the RAN DRX cycle configured for another SIM user.

In addition, if the user terminal does not report the UE SPECIFIC DRX cycle, or the network device does not configure the RAN DRX cycle, multiple SIM users can all use the CELL default DRX cycle. In this way, the DRX cycle of multiple SIM users is also the same.

Through the foregoing coordination of the DRX cycles of multiple user terminals, it can be ensured that the paging cycles determined by multiple SIM users are the same, or the paging cycles determined by multiple SIM users have an integer multiple relationship.

2. UE ID coordination

Based on the paging mechanism, it can be seen that the UE ID is used as one of the determining factors in the calculation of PF and PO. In order to make the paging time positions determined by multiple SIM users in the communication device consistent or partially consistent, the UE IDs used by multiple SIM users when determining the PF and PO may be consistent.

Specifically, when determining the paging time position of each SIM card user terminal among multiple SIM users, the UE ID of a certain SIM user among the multiple SIM users can be used, or a configured public UE ID can be used. In this way, it can be ensured that the UE IDs used by multiple SIM users when determining PF and PO are consistent. For example, multiple SIM users can negotiate with the network device which SIM user's UE ID to use as the UE ID for determining the paging time position. For example, use the UE ID corresponding to the primary SIM user. The network device can also specify which SIM user's UE ID to use. The network device can specify the UE ID that determines the paging time location to the user terminal during the network registration process initiated by the user terminal (for example, it can be the SIM user’s own UE ID, or it can be located in the same communication device as the SIM user. The UE ID of other SIM users).

Although multiple SIM users use the same UE ID when determining PF and PO, the UE ID carried in the paging message may also be the UE ID of each SIM user.

Of course, the network device can also send the same paging message to multiple associated SIM users. For example, a SIM user may receive the same paging message in the same PF and PO, and the paging message carries the UE ID determined through negotiation.

In addition, based on the paging mechanism, it can be known that the UE IDs of RRC IDLE and RRC INACTIVE user terminals are different. When the user terminal is in the RRC IDLE state, the CN initial paging is S-TMSI. When the user terminal is in the RRC INACTIVE state, the RAN initial paging is I-RNTI. Therefore, in different RRC states, the UE IDs of multiple SIM users to determine the paging time position may also be different.

3. Coordination of other parameters

Based on the paging mechanism, it can be known that parameters such as Ns (the number of POs in the PF) and PF_offset (determining the offset of the PF) also affect the paging time position of the user terminal. Therefore, if multiple SIM users in the same communication device camp on or access multiple different cells, these multiple cells also need to coordinate these parameters.

One way is that the network equipment can coordinate the consistency of these parameters through self-implementation. For example, the network equipment guarantees that the above-mentioned parameters of multiple cells are consistent.

Another way is that the communication device may report the above-mentioned parameters of at least one cell. After the network device is reported, it will coordinate between different cells and notify multiple SIM users of the result of the coordination, so that when paging is sent to multiple SIM users, the unified Ns, PF_offset and other paging parameters are used to determine Paging time location.

For the method for reporting the associated information of multiple SIM users in the communication device, reference may be made to the related description in the foregoing embodiment.

This application example is described by taking a multi-card terminal as an example. It should be understood that in other user terminal association scenarios, a similar manner can also be used to determine the paging time position of the user terminal.

Application example 2:

In a scenario where a mobile phone is associated with a wearable device, or in an operator's one-number multi-terminal scenario, multiple user terminals, such as UE1 and UE2, have an association relationship on the network side.

For these scenarios, the paging time position determination method of the foregoing embodiment and application example 1 can be referred to to determine the paging parameters, and then the paging time positions of the two UE1 and UE2 can be coordinated. UE1 and UE2 may have the same PO and PF.

Further, the paging messages of UE1 and UE2 can be bound. For example, UE1 and UE2 can be paged through an agreed UE ID. The agreed UE ID can be the UE ID of UE1, the UE ID of UE2, or the UE ID notified by the network, or the aforementioned UE ID used to determine the paging time position. In this way, the paging record list of the paging message sent by the network device may include the agreed UE ID.

After the network device sends a paging message to UE1 and UE2 at the determined PO and PF, if UE1 detects that the agreed UE ID is in the paging record list of the paging message, it can determine that it is paged. If UE2 detects that the agreed UE ID is included in the paging message, it can determine that it is paged.
