The main bodies shown in FIG1 are illustrative.

[0123] The following is an explanation and interpretation of the terminology used in this disclosure.

[0124] The User Account Control (UAC) mechanism determines whether a terminal's access attempt is prohibited based on access control parameters. These parameters may include at least one of the following: Public Land Mobile Network (PLMN) identifier (ID), access category (AC), access identity (AI), and UAC barring parameter.

[0125] In some embodiments, the AC is used to determine the type corresponding to the access attempt. Table 1 is a mapping table that maps access attempts to ACs. As shown in Table 1, there are a total of 64 access attempt types for ACs in the 5G system.

[0126] In some embodiments, the terminal determines the type of access attempt, maps it to the corresponding AC according to the AC mapping table, and considers the AC value during UAC checks to determine whether to initiate the access attempt. For example, if the terminal determines that the access attempt is a paging-initiated UE call, then the access attempt corresponds to AC 0.

[0127] Table 1

[0128] In some embodiments, AI is used to determine terminal configuration. Table 2 is a mapping table that maps terminal configuration to AI. As shown in Table 2, there are 16 types of AI. In some embodiments, terminal configuration is a description of the terminal's device type, terminal configuration type, etc. The terminal can determine its own AI value based on its own characteristics or based on the terminal's registration information on the network. When performing UAC checks, the AI ​​value is considered to determine whether to initiate the access attempt.

[0129] Table 2

[0130] In some embodiments, UAC blocking parameters may include a blocking factor (uac-BarringFactor), a blocking time (uac-BarringTime), and an access blocking identifier (uac-BarringForAccessIdentity).

[0131] In some embodiments, the prohibition factor represents the probability of allowing an access attempt during an access control check. In some embodiments, the prohibition time represents the average time required to execute a new access attempt after an access attempt is prohibited during an access control check for the same access type. In one embodiment, the prohibition time is used to configure a timer associated with the access type. After the timer expires, the terminal can initiate a new access attempt for the same access type. In some embodiments, the access prohibition flag indicates whether an access attempt is allowed for each access flag.

[0132] In some embodiments, the UAC prohibition parameter is typically a random number for ordinary users (AI 0-AI 10), while for high-priority users (AI 11-AI 15), it is a bitmap.

[0133] In some embodiments, the current UAC mechanism does not perform UAC checks on paging messages sent by network devices, whether they are sent by core network devices or access network devices. This is because network devices are aware of their own load when initiating downlink services, and can send paging messages without overloading. In this case, the paging message does not require UAC checks from the terminal's perspective. However, this method has drawbacks in some scenarios and may cause network congestion.

[0134] For example, a terminal receives a paging message in cell A, but the call response initiated by the terminal is in cell B. That is, the terminal performs cell reselection after receiving the paging message in cell A. In this case, the base station of cell A may not know the load situation of cell B, especially when cell A and cell B belong to different base stations. If cell B is congested, the terminal's call access in cell B may further aggravate the congestion in cell B, thereby affecting system performance.

[0135] For example, a base station sends a paging message on a common frequency band A, and a terminal receives the paging message on the same frequency band A. However, if the terminal initiates a call response on frequency band B, the base station may not be aware of the congestion situation on frequency band B. This is especially true if frequency band A and frequency band B belong to different base stations. If frequency band B is congested, the terminal initiating a call on frequency band B at this time may further exacerbate the congestion on frequency band B, thereby affecting system performance.

[0136] Therefore, how to perform UAC checks on access attempts triggered by paging messages is an urgent problem to be solved.

[0137] This disclosure provides a communication method, communication device, communication system, storage medium, and program product. A terminal performs an access control check on a first access attempt triggered by a first paging message. The first paging message is received by the terminal on a first frequency domain resource, which is different from the frequency domain resource dedicated to the terminal's stationary cell. Thus, the terminal can perform access control on access attempts of paging requests and responses in different cell scenarios, or on access attempts of paging requests and responses in different frequency domain resource scenarios, effectively avoiding network congestion caused by access triggered by paging messages and ensuring the quality of service of the communication system.

[0138] In some embodiments, the first paging message is a paging message received by the terminal on a first frequency domain resource, which is different from the frequency domain resource dedicated to the terminal's camp cell.

[0139] In some embodiments, the first paging message is received by the terminal on frequency domain resources outside the frequency domain resources dedicated to the stationary cell.

[0140] In some embodiments, the first paging message is a paging message received by the terminal in a cell outside the stationary cell.

[0141] In some embodiments, the first frequency domain resource includes at least one of the following: band A, frequency A, and carrier A.

[0142] In some embodiments, the first paging message is a paging message received by the terminal on frequency band A, which is different from the frequency band dedicated to the terminal's camping cell. In some embodiments, the first paging message is received by the terminal on frequency band A, which is outside the frequency band dedicated to the camping cell.

[0143] In some embodiments, the first paging message is a paging message received by the terminal on frequency A, which is different from the frequency dedicated to the terminal's camping cell. In some embodiments, the first paging message is received by the terminal on frequency A, which is other than the frequency dedicated to the camping cell.

[0144] In some embodiments, the first paging message is a paging message received by the terminal on carrier A, which is different from the carrier dedicated to the terminal's camping cell.

[0146] In some embodiments, the first paging message is a paging message received by the terminal on the frequency domain resources dedicated to the first cell, and the first cell is a cell other than the stationary cell.

[0147] In some embodiments, the first paging message is a paging message received by the terminal on a public frequency domain resource, which is different from the frequency domain resource dedicated to the terminal's camp cell.

[0148] In some embodiments, the first paging message is a paging message received by the terminal after receiving a wake-up signal. In some embodiments, the wake-up signal is a low-power wake-up signal (LP-WUS).

[0149] In some embodiments, the first paging message is a paging message for a specific call reason.

[0150] Understandably, the terminal performs a UAC check on access attempts (i.e., first access attempts) triggered by a specific type of paging message (i.e., the first paging message).

[0155] In some embodiments, the network device can send UAC parameters via broadcast messages. In some embodiments, the network device can send UAC parameters via system information. In one example, the system information is system information block 1 (SIB1). In some embodiments, the network device can send UAC parameters to the terminal via control signaling. In some embodiments, the control signaling can be at least one of radio resource control (RRC) signaling, media access control-control element (MAC-CE) signaling, and non-access stratum (NAS) signaling.

In some embodiments, the fifth information indicates a first access identifier. In some embodiments, the UAC parameters also include the access category shown in Table 1 and the access identifier shown in Table 2. Understandably, the network device adds new UAC parameters, namely the third, fourth, and fifth information, for the first access attempt triggered by the first paging message. This allows the terminal to perform UAC checks on the first access attempt based on the new UAC parameters, further improving the UAC mechanism for the first paging message, effectively avoiding network congestion caused by access triggered by the first paging message, and ensuring the quality of service of the communication system.

[0157] In some embodiments, the first access reason includes at least one of the following: a first paging message, a first paging message received based on a wake-up signal, cell reselection after receiving the paging message, and a wake-up signal.

[0164] In some embodiments, the first information is used by the terminal to determine whether to perform a UAC check on the first access attempt. In some embodiments, the first information indicates that a UAC check should be performed on the first access attempt.

[0165] In some embodiments, the network device may send first information to the terminal via control signaling. In some embodiments, the control signaling may be at least one of RRC signaling, MAC-CE signaling, and NAS signaling.

[0166] In some embodiments, step S2102 can be omitted. In this case, the terminal can determine whether to perform a UAC check on the first access attempt based on predefined information, service requirements, or its own implementation. In one example, the terminal can determine to perform a UAC check on the first access attempt based on protocol specifications.

[0167] In some embodiments, steps S2101 and S2102 can be executed simultaneously or in reverse order. In some embodiments, the access control parameters in step S2101 and the first information in step S2102 can be sent to the terminal in the same message or in different messages.

In some embodiments, the terminal can perform cell reselection between cells of the same frequency or between cells of different frequencies. In some embodiments, the terminal can perform cell reselection within the system or between systems.

[0187] In some embodiments, the terminal may perform cell reselection upon receiving a first paging message. In some embodiments, the terminal may perform cell reselection upon detecting downlink data transmission from a network device. In some embodiments, the terminal may perform cell reselection upon the network device updating system information. In some embodiments, the terminal may perform cell reselection when the signal quality of the first cell deteriorates. In some embodiments, the terminal may perform cell reselection when the signal quality of a neighboring cell of the first cell is better than that of the first cell.

[0240] Figure 3 is another interactive schematic diagram of the communication method provided according to an embodiment of the present disclosure. The communication method involved in the embodiment of the present disclosure can be applied to the communication system 100. As shown in Figure 3, the communication method of the embodiment of the present disclosure includes steps S3101 to S3102.

[0241] In step S3101, the network device sends a first paging message.

[0242] In some embodiments, the network device transmits a first paging message on a first frequency domain resource. In some embodiments, the network device includes an access network device or a core network device.

[0243] The optional implementation of step S3101 can also be found in the optional implementation of step S2103 in Figure 2A, and other related parts in the embodiments involved in Figure 2A, which will not be repeated here.

[0244] In step S3102, the terminal performs a UAC check on the first access attempt.

[0245] In some embodiments, the first access attempt is triggered by a first paging message, which is received by the terminal on a first frequency domain resource, which is different from the frequency domain resource dedicated to the terminal's camp cell.

[0246] The optional implementation of step S3102 can also be found in the optional implementation of step S2105 in Figure 2A, and other related parts in the embodiments involved in Figure 2A, which will not be repeated here.

[0247] The communication method involved in the embodiments of this disclosure may include at least one of steps S3101 to S3102. For example, step S3101 may be implemented as a standalone embodiment. For example, step S3102 may be implemented as a standalone embodiment.

[0248] In the following, the technical solutions of the embodiments of this disclosure will be described by way of specific implementation.

[0249] In some embodiments, the existing admission control parameters are structured for each PLMN, each access class, and each access identifier. The table below provides an example where the maximum number of PLMNs is 6, and the maximum number of access classes and access identifiers is 64 and 16, respectively.

[0250] In some embodiments, access categories are defined according to 3GPP TS24.301 as follows: mo-signalling, emergency calls, mo-MMTEL voice, mo-MMTEL video, mo-SMSoIP (Short Message over IP), mo-SMS (Short Message over IP), mt-calls (called calls), mo-calls (calling calls), and mobile originating CS fallback.

[0251] In some embodiments, the access identifier can be understood as an attribute of the UE, such as 0-9 for ordinary users and 11-15 for high-priority users.

[0252] In some embodiments, the UAC prohibition parameter defines a random number and the duration of the barring effect for non-special user identifiers; while for services with special user identifiers, a bitmap format is used.

[0253] In some embodiments, the basic UAC check process involves determining the terminal's access class, obtaining the UAC prohibition parameter, and performing the UAC check. In some embodiments, the parameter is typically a random number for ordinary users (0-9), while for high-priority users (11-15), it is in bitmap form. This parameter is usually defined in SIB2 as follows. For the random number method, if it is prohibited, a timer needs to be started, the duration of which is calculated from the prohibition time. Currently, the largest Barring timer is 512 seconds.

[0254] In some embodiments, the call establishment reason in the existing RRC connection establishment request includes at least one of the following: emergency, high priority access, called party access (mt-Access), calling party signaling (mo-Signalling), calling party data (mo-Data), calling party initiated audio call (mo-VoiceCall), calling party initiated video call (mo-VideoCall), calling party initiated SMS service (mo-SMS), MPS priority access (mps-PriorityAccess), and MCS priority access (mcs-PriorityAccess).

[0255] In some embodiments, the reasons for call establishment in the RRC resume establishment request are as follows: emergency, high priority access, called party access (mt-Access), calling party signaling (mo-Signalling), calling party data (mo-Data), calling party initiated audio call (mo-VoiceCall), calling party initiated video call (mo-VideoCall), and calling party initiated SMS service (mo-SMS).

[0256] In some embodiments, access control parameters are notified to the user in system messages. If the user finds that the access control parameters cannot be obtained during the decision-making process, a UAC check will not be performed.

[0257] In some embodiments, currently, no User Account Control (UAC) check is performed on paging messages, whether sent by the core network or the access network. This is because the base station is aware of the load status of network-initiated downlink services. When the base station sends a paging message in a certain cell, the terminal can respond to the paging message in that cell. If the base station knows the load status of that cell, it can initiate a paging message without overloading, and for the terminal, no UAC check is needed. However, in 6G networks, a paging message might be sent from cell A, but the terminal's call response might be in another cell B. Due to load balancing, the terminal may have reselected to cell B when initiating the call response, and the base station cannot know which cell B is specifically, thus unaware of its load status. This cell B might be a cross-base station. Therefore, if the terminal initiates a call access in cell B and cell B is congested, admission control is required. That is, the loads of cells A and B are different. Therefore, admission control is needed for calls initiated in cell B.

[0258] In some embodiments, the same issue arises when paging messages are initiated using a common frequency band. Therefore, admission control needs to be considered when paging requests and responses occur in different cells. This is because the load on the common frequency band sending the paging message and the cell responding to the call may differ. Thus, admission control is required for calls originating in a single cell.

[0259] In some embodiments, a UAC check is performed in response to a specific type of paging message (i.e., a first paging message) to initiate a call establishment (i.e., a first access attempt).

[0260] In some embodiments, a particular type of paging is a paging message received by the terminal in a cell outside of its current camping cell.

[0261] In some embodiments, a particular type of paging may also include a paging message for a particular call reason.

[0262] In some embodiments, a particular type of paging is a paging message received by the terminal on a frequency band / carrier outside the currently camped cell.

[0263] In some embodiments, a particular type of paging is a wake-up indication received via LP-WUS.

[0264] In some embodiments, a particular type of paging is a paging message received after a wake-up instruction received via LP-WUS.

[0265] In some embodiments, the terminal may be in an idle state (RRC idle) or an inactive state (RRC inactive).

[0266] In some embodiments, a paging message may be a paging message initiated by the core network (CN) or a paging message initiated by the access network (RAN).

[0267] In some embodiments, a UAC check is performed to initiate a call setup for a specific type of paging message response based on protocol agreement or network indication.

[0268] In some embodiments, additional triggering conditions can be added to the UAC check for initiating call establishment based on a specific type of paging message response, according to protocol agreements or network indications. For example, a UAC check is only required when the cell after terminal reselection and the cell receiving the paging message have crossed base stations. Otherwise, a UAC check is not required.

[0269] In some embodiments, a UAC check is performed if the network indicates that a call setup for a specific type of paging message response is required; otherwise, the existing mechanism is used, i.e., a UAC check is not required for a call setup for a paging message response.

[0270] In some embodiments, if the network indicates that a UAC check is not required for initiating a call setup in response to a paging message, a new call setup reason, such as "MT for LP-WUS", can be used to help the network distinguish whether the call setup message for the terminal was received from a cell outside the currently camped cell.

[0271] In some embodiments, new UAC parameters are added to initiate call setup for a specific type of paging message response. The new UAC parameters include at least one of the following: access category, access reason, and access identifier.

[0272] In some embodiments, the new access category may be "MT for LP-WUS".

[0273] In some embodiments, the new access reason may be "MT for LP-WUS".

[0274] In some embodiments, the new access identifier may be "UE with LR". Understandably, a terminal with an LR transceiver may reselect to another cell upon receiving a paging message.

[0275] In some embodiments, initiating call setup for a specific type of paging message response can reuse existing access control parameters, i.e., reuse at least one of existing call category, call setup reason, and call identifier.

[0276] In some embodiments, the access category can reuse the original "originating calls".

[0277] In some embodiments, the access reason can reuse the original "mt-Access".

[0278] In some embodiments, the network establishes broadcast admission control parameters for calls initiated in response to a specific type of paging message.

[0279] In some embodiments, for paging initiated by the core network, the terminal will trigger cell reselection upon receiving a specific type of paging message. If the reselection results in a different cell, the terminal will notify the higher layers of the new cell. This facilitates the higher layers, i.e., the NAS, in selecting the appropriate access category, access reason, and access identifier, and informing the AS layer of the terminal.

[0280] In some embodiments, the terminal will record the cell where it last camped or the cell where it received the paging message.

[0281] In some embodiments, if the terminal selects a different cell after reselection, the NAS is notified, and the NAS selects the appropriate AC, AI, and call setup reason.

[0282] In some embodiments, a UAC check is performed before the terminal initiates a call setup request.

[0283] In some embodiments, for paging initiated by the core network, the terminal will trigger cell reselection upon receiving a specific type of paging message. If the reselection results in a different cell, the AS layer will replace the UAC parameters indicated by the NAS with new UAC parameters, such as at least one of call type, call setup reason, and call identifier. In some embodiments, the terminal will record the cell where it last camped or the cell that received the paging information; in some embodiments, if the terminal selects a different cell after reselection, it will notify the NAS.

[0284] In some embodiments, the terminal will perform a UAC check using new UAC parameters before initiating a call setup request.

[0285] In some embodiments, for a paging initiated by a base station, the terminal will trigger cell reselection after receiving a specific type of paging message. If the cell reselection results in a different cell, a Resume request will be initiated in the new cell. In some embodiments, the terminal will record the cell where it last camped or the cell that received the paging information. In some embodiments, a UAC check will be performed before the Resume request.

For example, a terminal is proposed, which includes units or modules for implementing the steps performed by the terminal in any of the above methods.
