The network device 110 and the terminal 120 may be the specific devices described above and will not be repeated here. The communication equipment may also include other devices in the communication system 100, such as a network controller, a mobile management entity and other network entities, which is not limited in the embodiments of the present application.

[0042] It should be understood that the terms "system" and "network" are often used interchangeably in this article. The term "and / or" in this article is only a description of the association relationship of associated objects, indicating that three relationships can exist. For example, A and / or B can represent: A exists alone, A and B exist at the same time, and B exists alone. In addition, the character " / " in this article generally indicates that the associated objects before and after are in an "or" relationship.

[0043] To facilitate understanding of the technical solutions of the embodiments of the present application, the technical solutions related to the embodiments of the present application are described below.

[0044] As people pursue higher speed, latency, high-speed mobility, energy efficiency, and the diversity and complexity of services in future life, the 3rd Generation Partnership Project (3GPP) international standard organization has begun to develop 5G. The main application scenarios of 5G are: enhanced mobile broadband (eMBB), ultra-reliable low-latency communications (URLLC), and massive machine-type communications (mMTC).

[0045] On the one hand, eMBB still aims at users to obtain multimedia content, services and data, and its demand is growing rapidly. On the other hand, since eMBB may be deployed in different scenarios, such as indoors, in urban areas, and in rural areas, its capabilities and requirements vary greatly, so it cannot be generalized and must be analyzed in detail in combination with specific deployment scenarios. Typical applications of URLLC include: industrial automation, power automation, remote medical operations (surgery), traffic safety, etc. Typical features of mMTC include: high connection density, small data volume, latency-insensitive services, low cost and long service life of modules, etc.

[0046] RRC Status

[0047] In order to reduce air interface signaling and quickly restore wireless connections and data services, 5G defines a new Radio Resource Control (RRC) state, namely the RRC inactive (RRC_INACTIVE) state. This state is different from the RRC idle (RRC_IDLE) state and the RRC active (RRC_ACTIVE) state.

[0048] 1) RRC_IDLE state (abbreviated as idle state): Mobility is based on cell selection and reselection of terminal equipment, paging is initiated by the core network (CN), and the paging area is configured by the CN. There is no terminal equipment context on the base station side, and there is no RRC connection.

[0049] 2) RRC_CONNECTED state (referred to as connected state): There is an RRC connection, and there is a terminal device context on the base station side and the terminal device side. The network side knows the location of the terminal device at the specific cell level. The mobility is the mobility controlled by the network side. Unicast data can be transmitted between the terminal device and the base station.

[0050] 3) RRC_INACTIVE state (abbreviated as inactive state): Mobility is based on the cell selection reselection of the terminal device, there is a connection between the access network and the core network, the context of the terminal device exists on a base station, paging is triggered by the Radio Access Network (RAN), the paging area based on RAN is managed by RAN, and the network side knows the location of the terminal device based on the RAN paging area level. When the terminal device moves within the Radio Access Network Notification Area (RNA) configured by the RAN, it does not need to notify the network side, but when it moves out of the RNA, it needs to notify the network side.

[0051] Network Slicing

[0052] In order to meet the requirements of vertical industries for latency, mobility, reliability, location accuracy, etc., RAN needs to enhance how to support vertical services in the access network. One way is to provide lower latency, more targeted, greater flexibility and higher scalability services for multiple services with different needs based on network slicing (also referred to as slicing). More specifically, network slicing allows application providers to participate in the design, deployment and operation of customized RAN to better support the business of application providers.

[0053] The network slicing of Rel-15 only involves the core network side. Specifically, the terminal device reports the slicing requirements (i.e. the slicing information required by the terminal device), and the network selects the appropriate AMF based on the slicing requirements reported by the terminal device to establish a service session between the terminal device and the network.

[0054] The network can only know the slice requirement of the terminal device after receiving MSG5. However, the slice requirement of the terminal device may not be supported by the base station, or the slice is overloaded even if it is supported by the base station. At this time, the network can only send an RRC release message to the terminal device after MSG5, so that the terminal device can reselect a suitable cell.

[0055] Dual SIM dual standby / dual network dual standby

[0056] A dual-SIM dual-standby phone means that a phone can hold two communication cards at the same time, and both communication cards are in standby mode. Dual-SIM dual-standby generally refers to dual-SIM dual-standby of the same network standard, such as dual-SIM dual-standby of GSM network, dual-SIM dual-standby of CDMA network, and dual-SIM dual-standby of PHS network.

[0057] Dual-network dual-standby means that a mobile phone can be inserted with two communication cards of different networks at the same time and be turned on at the same time. Users can make calls, receive calls and send and receive text messages at will without switching networks.

[0058] At present, mobile phones generally do not support pure dual-transmit and dual-receive (abbreviated as dual-pass), which means that the mobile phone simultaneously sends uplink and receives downlink data on two networks through two communication cards. Generally speaking, most mobile phones only support single-transmit and single-receive or single-transmit and dual-receive, which means that the mobile phone can only execute the service on one communication card at a time. However, achieving dual-pass is a trend in the development of mobile phones in the future. In 5G, for the two communication cards of mobile phones that support dual-card dual standby or dual-network dual standby, one of the communication cards can reside in the LTE cell and the other communication card can reside in the NR cell; or, both communication cards reside in the NR cell. On the other hand, the two communication cards can be communication cards of the same operator or communication cards of different operators.

[0059] After a communication card of a terminal device receives a paging message, it will directly enter a connected state to receive service data. However, in some cases, it is not necessary for the terminal device to respond to the paging message. Therefore, it is necessary to indicate the relevant information of triggering the paging so that the terminal device can determine whether it should respond to the paging message. How to indicate the relevant information of triggering the paging needs to be solved. To this end, the following technical solution of the embodiment of the present application is proposed.

[0060] It should be noted that the "terminal device" in the embodiments of the present application can be a mobile phone, a tablet computer, a wearable device, etc. The terminal device can have one communication card (i.e., applied to a single-card scenario), or multiple communication cards (i.e., applied to a multi-card communication scenario), for example, the terminal device has 2 communication cards or 3 communication cards, etc. The following embodiments are described by taking the first communication card of the terminal device as an example, but are not limited to this. The solution of two or more communication cards is also applicable to the technical solution of the embodiments of the present application.

[0061] In an embodiment of the present application, the terminal device has at least a first communication card. For a multi-card scenario, the terminal device may also have a second communication card. The network corresponding to the first communication card is the first network, and the network corresponding to the second communication card is the second network. The first communication card is registered on the first network, and the second communication card is registered on the second network.

[0062] It should be noted that the embodiment of the present application does not limit the types of the first communication card and the second communication card. For example, the first communication card and the second communication card are both subscriber identity module (Subscriber Identity Module, SIM) cards. For example, the first communication card and the second communication card are both universal subscriber identity module (Universal Subscriber Identity Module, USIM) cards. For example, the first communication card is a SIM card, and the second communication card is a USIM card. For example, the first communication card is a USIM card, and the second communication card is a SIM card. On the other hand, the embodiment of the present application does not limit the network types supported by the first communication card and the second communication card, for example, the first communication card supports the LTE network (that is, the first base station corresponding to the first communication card is an LTE base station), and the second communication card supports the NR network (that is, the second base station corresponding to the second communication card is an NR base station). For example, the first communication card and the second communication card both support the NR network (that is, the first communication card and the second communication card and the second communication card The second base station is an NR base station). On the other hand, the embodiment of the present application does not limit the operator to which the first communication card and the second communication card belong, for example, the first communication card and the second communication card can belong to the same operator or different operators.

[0063] It should be noted that the communication between the terminal device and the first network is realized through the first communication card, and the communication between the terminal device and the second network is realized through the second communication card. For example, there are two USIM cards in the terminal device, namely USIM-A card and USIM-B card. Among them, the terminal device can communicate with the first network through the USIM-A card, and the terminal device can communicate with the second network through the USIM-B card.

[0064] Figure 2 is a flow chart of the paging indication method provided in the embodiment of the present application, such as Figure 2 As shown, the paging indication method includes the following steps:

[0065] Step 201: The first network sends a paging message to the terminal device, and the terminal device receives the paging message sent by the first network, where the first network refers to the network corresponding to the first communication card of the terminal device; wherein the paging message carries at least one information unit, and each information unit in the at least one information unit is used to indicate at least one of the following information of a paged terminal device: paging reason, paging priority, and slice information.

[0066] In the embodiment of the present application, the first communication card of the terminal device is in an idle state or an inactive state. In this case, the terminal device receives a paging message sent by a first network corresponding to the first communication card, and the paging message is used to page the first communication card.

[0067] In an embodiment of the present application, the paging message carries at least one information unit, and each information unit in the at least one information unit is used to indicate at least one of the following information of a paged terminal device: paging reason, paging priority, and slice information.

[0068] In an optional manner, the paging reason is the service type that triggers the paging.

[0069] In an optional manner, the paging priority is a service priority that triggers paging.

[0070] In an optional manner, the slice information includes at least one of the following: a slice identifier, a slice type, and a slice indication information; wherein the slice indication information and the slice identifier have a corresponding relationship. Further, optionally, the corresponding relationship between the slice indication information and the slice identifier is determined by protocol agreement, or by system broadcast information configuration, or by RRC signaling configuration, or by NAS signaling configuration. Here, each slice has a corresponding switching identifier, which can also be called a switching index.

[0071] In one example, the switching information includes first switching indication information, and the first switching indication information has a corresponding relationship with the first slice identifier. The terminal device can determine the first slice identifier through the first switching indication information and the corresponding relationship.

[0072] In an embodiment of the present application, the paging message carries at least one information unit, which can be implemented in the following manner: the paging message carries a first bitmap, and every N bits in the first bitmap correspond to an information unit, where N is a positive integer.

[0073] In an optional manner, the paging message further carries first indication information, and the first indication information is used to indicate the value of N. Here, the first indication information is used to indicate how many bits in the first bitmap constitute an information unit. The size of an information unit (i.e., the number of bits occupied by an information unit) is configurable. In other words, the size of an information unit is variable.

[0074] In an optional manner, when the paging message does not carry the first indication information, the value of N is a default value. For example, the default value of N is 1, in other words, the size of an information unit is 1 bit.

[0075] In the above scheme, the size of an information unit may also be referred to as unitSize.

[0076] In the embodiment of the present application, the values ​​of the N bits are used to represent the information content indicated by the information unit corresponding to the N bits. Further, optionally, the correspondence between the values ​​of the N bits and the information content represented is agreed upon by a protocol or configured by system broadcast information.

[0077] In the above scheme, the first bitmap can also be called pagingCauseBitmap. The size of the first bitmap is variable, and the size of the first bitmap changes with the number of paging records in the first paging record list PagingRecordList. Specifically, the first bitmap includes M bits, and the value of M is associated with the number of paging records included in the first paging record list, and M is a positive integer. For example: the value of M is the number of paging records included in the first paging record list multiplied by N.

[0078] In one example, under different unitSizes configured in the protocol agreement or system broadcast information, different values ​​of the N bits occupied by the information unit represent different meanings.

[0079] For example, if unitSize=2 (i.e., N=2), then the 2-bit information unit indicates four types of information contents. An example is given below:

[0080] 00: the indicated information content includes at least one of the following: voice service type, priority 1, slice information 1 (for example, slice identifier 1);

[0081] 01: The indicated information content includes at least one of the following: video service type, priority 2, slice information 2 (e.g., slice identifier 2);

[0082] 10: The indicated information content includes at least one of the following: stream service type, priority 3, slice information 3 (e.g., slice identifier 3);

[0083] 11: The indicated information content includes at least one of the following: other service type, priority 4, slice information 4 (for example, slice identifier 4).

[0084] For example, if unitSize=1 (i.e., N=1), then a 1-bit information unit indicates two types of information content. An example is given below:

[0085] 00: the indicated information content includes at least one of the following: voice service type, high priority, slice information 1 (e.g., slice identifier 1);

[0086] 01: The indicated information content includes at least one of the following: other service type, low priority, slice information 2 (for example, slice identifier 2).

[0087] In an embodiment of the present application, the first paging record list includes P paging records, where P is a positive integer; the first bit map has a corresponding relationship with an information unit for every N bits in order from low to high, wherein the first bit map has a corresponding relationship with the P information units, and the P information units correspond one-to-one to the P paging records.

[0088] If the first paging record list includes 5 paging records (paging record), that is, P=5, the first bit map (i.e., pagingCauseBitmap) includes 10 bits, where every two bits represent an information unit, and there are a total of 5 information units. According to the pagingCauseBitmap from low to high, every 2 bits correspond to one information unit, and the 5 information units correspond one-to-one to the first paging record, the second paging record, the third paging record, the fourth paging record and the fifth paging record in the first paging record list, respectively.

[0089] Table 1 shows the information content of pagingCauseBitmap. It should be noted that the value range of the size of pagingCauseBitmap in Table 1 is 1 to 32, and the value 1 to 32 here is only for exemplary description.

[0090]

[0091] Table 1

[0092] In the embodiment of the present application, the location of the slice information can be in the following two ways.

[0093] Method 1: The slice information indicated by the information unit is carried in the paging record corresponding to the information unit in the first paging record list, and each paging record in the first paging record list also carries at least one of the following: terminal device identification, access type.

[0094] Specifically, taking the slice information as a slice identifier (slice id) as an example, for the slice identifier, the slice identifier indicated by each information unit is included in the paging record corresponding to the information unit, refer to the following Table 2, wherein the single network slice selection assistance information (Single Network Slice Selection Assistance Information, S-NSSAI) represents the slice identifier.

[0095]

[0096] Table 2

[0097] Method 2: The slice information indicated by the information unit is carried in the paging record corresponding to the information unit in the second paging record list. The paging records in the second paging record list correspond one-to-one to the paging records in the first paging record list. Each paging record in the first paging record list carries at least one of the following: terminal device identification, access type.

[0098] Specifically, taking the slice information as a slice identifier (slice id) as an example, a new Pagingrecordlist (i.e., the second paging record list) is configured for the slice identifier, and each paging record (paging record) in the new Pagingrecordlist carries a slice identifier. The paging records in the new Pagingrecordlist correspond one-to-one to the paging records in the previously configured Pagingrecordlist carrying the UE id, and each paging record in the new Pagingrecordlist indicates the slice identifier of the paging of each terminal device. Refer to the following Table 3, where S-NSSAI represents the slice identifier.

[0099]

[0100]

[0101] Table 3

[0102] In the technical solution of the embodiment of the present application, at least one of the paging reason, the paging priority and the switching information is indicated by a bit map, and the length of the bit map is also indicated.

[0103] It should be noted that the technical solution of the embodiment of the present application can be but is not limited to being applied in a dual-SIM scenario.

[0104] In an optional method of the present application, the first network sends system broadcast information, and the terminal device receives the system broadcast information sent by the first network, and the system broadcast information carries second indication information and / or third indication information; wherein the second indication information is used to indicate whether the first network supports sending the information unit or paging reason; and the third indication information is used to indicate whether the first network supports receiving departure indication information or busy indication information sent by the terminal device.

[0105] Further, after receiving the second indication information, the terminal device has the following processing mode:

[0106] If the second indication information indicates that the first network supports sending the information unit or paging reason, then after receiving the paging message, the terminal device determines whether to respond to the paging message based on the information unit or paging reason in the paging message. For example: if the service that triggers the paging belongs to service type 1, respond to the paging message; if the service that triggers the paging belongs to service type 2, do not respond to the paging message. For example: if the service that triggers the paging is a high-priority service, respond to the paging message; if the service that triggers the paging is a low-priority service, do not respond to the paging message.

[0107] If the second indication information indicates that the first network does not support sending the information unit or the paging reason, after receiving the paging message, the terminal device accesses the first network and determines whether to continue to stay in the first network or leave the first network.

[0108] Further, after receiving the third indication information, the terminal device has the following processing mode:

[0109] If the third indication information indicates that the first network supports receiving leave indication information or busy indication information sent by the terminal device, the terminal can send a message carrying the leave indication information or the busy indication information.

[0110] Figure 3 The structure of the paging indication device provided in the embodiment of the present application is shown in FIG. Figure 1 , applied to terminal devices such as Figure 3 As shown, the paging indication device includes:

[0111] The receiving unit 301 is configured to receive a paging message sent by a first network, where the first network refers to a network corresponding to a first communication card of the terminal device;

[0112] The paging message carries at least one information unit, and each of the at least one information unit is used to indicate at least one of the following information of a paged terminal device: paging reason, paging priority, and slice information.

[0113] In an optional manner, the paging message carries a first bit map, and every N bits in the first bit map correspond to an information unit, where N is a positive integer.

[0114] In an optional manner, the paging message further carries first indication information, where the first indication information is used to indicate a value of N.

[0115] In an optional manner, when the paging message does not carry the first indication information, the value of N is a default value, wherein the first indication information is used to indicate the value of N.
