[0002] This application claims priority to Chinese Patent Application No. 201910798446.6, filed in China on August 27, 2019, the entire contents of which are incorporated herein by reference. Technical Field

[0003] This disclosure relates to the field of communications, and more particularly to a paging method and device. Background Technology

[0004] The 3rd Generation Partnership Project (3GPP) defines the process for paging users in mobile network final call services, as follows:

[0005] First, a session connection is established between the terminal and the network, including a wireless connection between the terminal and the base station and a core network connection between the base station and the User Plane Function (UPF). The terminal communicates with the application server through the above session connection. After determining that the terminal has no user data transmission within a certain period of time, the base station decides to suspend the terminal, that is, release the wireless resources between the terminal and the terminal, but still retains the core network connection between the base station and the User Plane Function.

[0006] Then, the application server sends application data. After the application data arrives at the UPF, the UPF forwards the application data to the base station through the core network connection.

[0007] Finally, the base station sends a paging message, such as a Page message, to the terminal. After receiving the paging message, the terminal initiates a wireless connection reconstruction process to re-establish the wireless connection between the terminal and the base station.

[0008] In related technologies, base stations can receive data related to the final call service, etc. However, how to obtain the matching value related to the final call service based on the aforementioned data related to the final call service is a technical problem that urgently needs to be solved in related technologies.

[0059] 3) Target flow identifier and one or more target service type information;

[0060] 4) Target flow identifier, target session identifier, and one or more target service type information.

[0061] It should be noted that this is just an example of a (target) business flow relationship. In reality, the business flow relationship information includes one or more business flow relationships as shown in the example above.

[0062] It should also be noted that the term "target..." mentioned in the various embodiments of this specification, such as target business information, is only used to facilitate the description of a specific piece of business information and does not represent any other specific meaning.

[0063] The above business matching information is used to obtain matching values ​​based on business information or business type information.

[0064] For a detailed explanation of business information and business type information, please refer to the description above.

[0065] Optionally, the aforementioned business matching information includes one or more business matching relationships. For any one of these business matching relationships (hereinafter referred to as the target business matching relationship for ease of distinction), it may include:

[0066] A target matching value and one or more target business information, wherein the target business information is used to indicate the business related to the target matching value; or,

[0067] The target matching value and one or more target business type information, wherein the target business type information is used to indicate the business type associated with the target matching value.

[0068] Of course, a business matching relationship usually includes a matching value, and different business matching relationships include different matching values.

[0069] Optionally, the above business matching information may also include validity period information.

[0070] Regarding the target business matching relationship mentioned above, it also includes at least one of the following:

[0071] 1) One or more high-priority service information, wherein the service corresponding to the high-priority service information can preempt the service corresponding to the target service information;

[0082] Optionally, the stream matching information may also include validity period information.

[0083] The paging method provided in this disclosure allows the network function to send service matching information and service flow relationship information, or send flow matching information, to the network device. In this way, the network device can obtain the matching value based on the flow identifier or "flow identifier and session identifier" through the service matching information and service flow relationship information, or obtain the matching value through the flow matching information. This solves the problem that the network device cannot determine the matching value related to the final call service and improves communication effectiveness.

[0084] To illustrate the paging method provided in this disclosure in detail, several specific embodiments will be described below.

[0085] Example 1

[0086] Figure 2 illustrates the process of suspending service establishment and triggering wireless paging in the paging method provided in this embodiment. As shown in Figure 2, this embodiment includes the following steps:

[0087] Step 201: The AMF is configured with service matching information, which contains one or more service matching relationships. For any one of these service matching relationships, it includes at least a matching value (e.g., a policy identifier in a policy matching relationship, and a cause value in a cause matching relationship), and one or more service information corresponding to that matching value; or one or more service type information corresponding to that matching value.

[0088] The following example illustrates the business matching relationship, which includes a matching value and one or more business information corresponding to that matching value. It can be understood that when the business matching relationship includes a matching value and one or more business type information corresponding to that matching value, the execution process is similar to the above-described process and will not be repeated here.

[0089] The aforementioned business matching relationships can be policy-based or cause-based. The business matching information may also include validity period information, indicating that the relevant information will be updated before the expiration date.

[0090] Optionally, if the aforementioned business matching information is strategy matching information, it may further include priority information corresponding to each business piece of information; or, one or more high-priority business pieces of information corresponding to each business piece of information; or, one or more low-priority business pieces of information corresponding to each business piece of information. Multiple pieces of business information may correspond to the same one or more high / low-priority business pieces of information.

[0091] The high-priority service information indicated above can preempt one or more services corresponding to it; the low-priority service information indicated above cannot interfere with one or more services corresponding to it.

[0092] For the aforementioned business information, or high / low priority business information, it may include the name of the business, such as WeChat, QQ, IMS Voice call, IMS Video call, a game name, etc.; it may also include the name and / or identifier of the business type, such as business type identifier 1 corresponding to the business type name "Instant Messaging", such as WeChat or QQ, business type identifier 2 corresponding to the business type name "IMS", such as voice or video call, business type identifier 3 corresponding to the business type name "Game", etc.; it may also include business identifiers, such as 1 for WeChat, 2 for IMS Voice call, 3 for QQ, etc.

[0093] Optionally, the aforementioned service information, or high / low priority service information, may also include session identifiers and / or flow identifiers (i.e., "session identifiers and flow identifiers", session identifiers, or flow identifiers) corresponding to each service / service type during the terminal session establishment process, and may also include service initiator information, such as the calling number of the IMS.

[0094] A matching value corresponding to multiple business information can also be represented as each of these multiple business information corresponding to the same matching value; multiple business information can correspond to one or more high / low priority business information.

[0095] SMF is configured with business rule information (referred to as rule information), or business identification rules. This business rule information includes at least one of the following: one or more IP addresses, which may include numbers or wildcards; one or more port numbers, which may include numbers or wildcards; one or more protocol information (such as RTP protocol based on TCP protocol); one or more encoding / decoding information, for example, voice code can identify voice service, and video codec can identify video service.

[0096] Step 202: The terminal is triggered by the network (e.g., receiving a paging message) or actively triggered by the terminal (e.g., having data to send) to the AMF on the network side to send a session establishment message, such as sending a PDU Session Establishment Request message.

[0097] Step 203: The AMF selects the SMF and sends a context establishment request to the SMF, such as sending a Create SM Context Request message.

[0098] Step 204: The SMF generates a session identifier (PDU Session ID) for the session to be established, assigns a flow identifier (QFI - QoS Flow ID) to each service / service type / application in the session, and generates corresponding packet detection rules (including at least one of the identification rules, flow identifier, and session identifier) ​​based on the identification rules of each service / service type / application and the corresponding flow identifier. When notifying the UPF to allocate uplink user plane resources, the packet detection rules are sent to the UPF at the same time.

[0099] Step 205: The SMF sends a context establishment response message to the AMF, such as a Create SM Context Response message, carrying service flow relationship information. For a detailed description of the service flow relationship information, please refer to the previous embodiment.

[0100] AMF can generate flow matching information based on service matching information and service flow relationship information, that is, replace the service information (or service type information) in the service matching information with the corresponding flow identifier, or replace it with "session identifier and flow identifier".

[0101] In the above business matching relationship, if the business information also includes one or more high-priority business information, one or more low-priority business information, or priority information, AMF can also replace the above high / low priority business information with flow identifiers or "session identifiers and flow identifiers". Of course, it can also not replace them, but simply add the flow identifiers or "session identifiers and flow identifiers" corresponding to the high / low priority business information.

[0102] Optionally, the SMF may also carry service flow relationship information in the communication message forwarding request message (such as a Communication N1N2 Message Transfer message) sent to the AMF. The allocated uplink resource information (such as an uplink tunnel identifier) ​​can be carried in the context establishment response message or in the communication message forwarding request message, and then sent to the base station.

[0103] Step 206: The AMF sends a radio resource allocation request to the base station, such as sending an N2 PDU Session Request message.

[0104] Optionally, the AMF can transparently transmit the service flow relationship information sent by the SMF to the base station through this radio resource allocation request, and carry service matching information in this message.

[0105] Optionally, the AMF carries flow matching information in this radio resource allocation request, and the uplink resource information sent by the SMF can be transparently transmitted to the base station by the AMF through this message.

[0106] In another embodiment, the AMF first sends the service matching information to the base station in other processes, such as the terminal registration process, for example, by sending the service matching information to the base station through a Registration Accept message.

[0107] Step 207: The base station and the terminal negotiate the allocation of radio bearer resources.

[0108] Step 208: The base station sends a radio resource allocation response to the AMF, such as sending an N2 PDU Session Response message, carrying the base station's downlink resource information.

[0109] Step 209: The AMF sends a context update to the SMF, such as sending an Update SM Context message. The AMF then forwards downlink resource information to the SMF through this message.

[0110] Step 210: SMF notifies UPF to perform downlink user plane resource allocation and notifies UPF of downlink resource information.

[0111] At this point, the terminal and the network have established uplink and downlink user plane communication connections, including the wireless connection between the terminal and the base station and the core network connection between the base station and the UPF.

[0112] Step 211: Sometime after the session is established, the base station decides to suspend the terminal and release radio resources, so it sends a message to the terminal to notify it of the suspension, such as sending an RRC Suspend message.

[0113] Step 212: The base station and the terminal release wireless resources.

[0114] Step 213: At some point later, the application server sends application data to the terminal, or sends information related to the application data. The following will take the example of the application server sending application data.

[0115] Step 214: Application data arrives at UPF. UPF matches user data to the corresponding core network connection based on the configuration information obtained during resource allocation, and transmits downlink data to the base station through the core network connection. In addition to application data, downlink data may also contain at least one of session identifier and flow identifier.

[0116] Step 215: The base station finds the matching value corresponding to the application data based on at least one of the session identifier and the flow identifier. For example, it can find the service information from the service flow relationship information and then find the matching value through the service matching information, or directly find the matching value from the flow matching information.

[0117] Step 216: The base station sends a paging message, such as a Page message, to the terminal. The paging message carries a matching value. After receiving the paging message, the terminal decides whether to respond to the paging message based on the matching value. That is, it either initiates a rebuild request to establish a wireless connection with the mobile network, or it notifies the user that there is service data to receive.

[0118] Optionally, the terminal side also stores business matching information.

[0119] After receiving a paging message carrying a matching value, the terminal decides whether to respond to the paging message, i.e., whether to initiate a service request to establish a connection with the mobile network, based on the matching value.

[0120] For example, the terminal decides whether to respond based on the priority information corresponding to the matching value; or based on the acceptable matching value of the service being executed; or based on whether the matching value corresponding to the service information of other services that the service being executed can accept a response to includes the matching value in the paging message.

[0121] For example, the terminal finds the service information corresponding to the matching value based on the matching value, and prompts the user with the service information, allowing the user to decide whether to accept the corresponding service.

[0122] This implementation is particularly suitable for terminals with multiple Universal Subscriber Identity Modules (USIMs), because paging a USIM card may interrupt a user's ongoing service using another USIM card. This implementation can proactively prompt for services related to paging, allowing the terminal to choose whether to accept paging based on user preference, thereby improving communication flexibility and enhancing user experience.

[0123] Example 2

[0124] Figure 3 is a flowchart of the paging method provided in this embodiment of the present disclosure, in which service is suspended after establishment and wireless paging is triggered. As shown in Figure 3, this embodiment includes the following steps:

[0125] Step 301: Same as the process described in steps 201 to 212, the terminal establishes a session through the mobile network and then suspends the session.

[0126] Step 302: Optionally, the terminal notifies the base station of the service information of another active USIM, such as by sending an RRC Early Data Request message carrying the service information. In this embodiment, the terminal may have multiple USIMs installed.

[0127] Step 303: At some point later, the application server sends application data or information related to application data to the terminal. The following will take sending application data as an example.

[0128] Step 304: Application data arrives at UPF. UPF matches user data to the corresponding core network connection based on the configuration information obtained during resource allocation, and transmits downlink data to the base station through the core network connection. In addition to application data, downlink data also contains at least one of session identifier and flow identifier.

[0129] Step 305: The base station finds the matching value corresponding to the application data based on at least one of the session identifier and the flow identifier. For example, it can find the service information from the service flow relationship information and then find the matching value through the service matching information, or directly find the matching value from the flow matching information.

[0130] In this embodiment, the base station may decide whether to perform paging based on the flow identifier, or based on the "session identifier and flow identifier" and service flow relationship information and service matching information, or based on the flow identifier or the "session identifier and flow identifier" and flow matching information.

[0131] For example, the base station finds the priority of the corresponding service information (referred to as the target service information for ease of distinction) in the service matching information, and finds the corresponding priority of the service information corresponding to the service currently active by the terminal (hereinafter referred to as the active service information) in the service matching information. The two priorities are compared. If the priority of the target service information is lower, that is, lower than the priority of the active service information, the paging is rejected, and the SMF can be notified optionally. Alternatively, the base station finds the low-priority service information corresponding to the active service information in the matching information. If the target service information is among the aforementioned low-priority service information, the paging is rejected. Or, the base station finds the high-priority service information corresponding to the active service information in the service matching information. If the target service information is among the high-priority service information, the paging is performed.

[0132] For example, based on flow matching information, the base station finds the priority of the flow identifier corresponding to the service data (called the target flow identifier) ​​and the priority of the active service information, compares the two priorities, and if the priority of the target flow identifier is lower, it refuses to perform paging and may optionally notify the SMF; or, it finds the low-priority service information corresponding to the active service information in the flow matching information, and if the target flow identifier is in the low-priority service information, it refuses to perform paging; or, it finds the high-priority service information corresponding to the active service information in the flow matching information, and if the target flow identifier is in the high-priority service information, it performs paging.

[0133] Step 306: When the base station performs paging, it sends a paging message, such as a Page message, to the terminal. The paging message carries a matching value.

[0134] After receiving a paging message carrying a matching value, the terminal decides whether to respond to the paging message, i.e., whether to initiate a service request to establish a connection with the mobile network, based on the matching value.

[0135] Optionally, the terminal side also stores business matching information.

[0136] For example, the terminal decides whether to respond based on the priority information corresponding to the matching value; or based on the acceptable matching value of the service being executed; or based on whether the matching value corresponding to the service information of other services that the service being executed can accept a response to includes the matching value in the paging message.

[0137] For example, the terminal finds the service information corresponding to the matching value based on the matching value, and prompts the user with the service information, allowing the user to decide whether to accept the corresponding service.

[0138] This implementation method is particularly suitable for terminals with multiple USIMs. It can proactively prompt paging-related services, allowing the terminal to choose whether to accept paging based on user preferences, thereby improving communication flexibility and enhancing user experience.

[0139] It should be noted that in step 305, the base station has already determined whether to perform paging. After performing paging, the terminal determines again whether to respond to paging. This implementation method mainly takes into account that the terminal may generate new service matching information but has not notified the network in time, thereby increasing the terminal's initiative in whether to respond to paging and improving the user experience.

[0140] The paging method according to an embodiment of the present disclosure has been described in detail above with reference to Figures 1 to 3. The paging method according to another embodiment of the present disclosure will now be described in detail with reference to Figure 4.
