Technical Field

[0002] The present disclosure relates to the field of communication technology, and in particular to a paging method, device, and storage medium. Background Art

[0003] A user equipment (UE) may use discontinuous reception (DRX) in the radio resource control idle state (RRC_IDLE) and the radio resource control deactivated state (RRC_INACTIVE) to reduce power consumption.

The network device can be used to interchange received air frames with Internet Protocol (IP) packets, acting as a router between the wireless terminal device and the rest of the access network, wherein the rest of the access network may include an Internet Protocol (IP) communication network. The network device may also coordinate the attribute management of the air interface. In some network structures, the network device may include a centralized unit (CU) node and a distributed unit (DU) node, and the centralized unit and the distributed unit may also be arranged geographically separately. The network device involved in the embodiments of the present disclosure may be a core network device.

[0184] The terminal device in the embodiment of the present disclosure sends relevant information or similar descriptions to the network side device, which only indicates that the terminal device sends the relevant information in the form of a wireless signal, and its intended recipient is the network device. The network device can obtain the relevant information by receiving the wireless signal.

[0185] The following first introduces the paging mechanism.

[0186] To minimize power consumption, the UE switches to a power-saving state (RRC_IDLE or RRC_INACTIVE) when no services are active. During this time, the core network cannot determine the UE's precise location, namely, which cell the UE is in, and data transmission is impossible. Therefore, when data arrives from the UE, the core network must use a paging mechanism to locate the UE. The core network / Next Generation Radio Access Network (NG-RAN) delivers paging messages to the UE, using the Physical Downlink Shared Channel (PDSCH) indicated by the Physical Downlink Control Channel (PDCCH) to carry these messages. The UE only wakes up during fixed periods to receive paging messages and can sleep the rest of the time to reduce power consumption and maximize battery life. Each wake-up period is called a DRX cycle. During this DRX cycle, the UE monitors the PDCCH, receives paging messages sent to it, and triggers the Random Access Channel (RACH) to enter the Connected state to receive downlink data.

[0187] When DRX is enabled, the UE transmits the UE-specific paging cycle (UE-Specific DRX) to the Access and Mobility Management Function (AMF) during the initial registration and mobility registration processes. The AMF accepts or modifies the UE-Specific DRX sent by the UE based on operator policy and stores it in the Registration Management-Unregistered (RM-DEREGISTERED) context. When the AMF pages the UE, it carries the DRX message to the gNB via an NGAP paging message. The formula for calculating the UE's monitoring paging cycle is as follows:

[0188] UE monitoring paging cycle = min (cell default paging cycle, UE specific DRX).

[0189] For UEs in RRC_IDLE and RRC_INACTIVE states, the UE will only wake up once at its corresponding paging time in each paging cycle. The location where the paging message appears in the air interface is fixed, which is represented by the paging frame (PF) and the paging occasion (PO). PO is a set of PDCCH monitoring moments, which can be composed of multiple time slots (for example, subframes or orthogonal frequency division multiplexing (OFDM) symbols), in which paging downlink control information (DCI) can be sent. A PF is a radio frame that can contain one or more POs or the starting point of a PO.

[0190] The UE calculates its own paging time by determining the PF and PO. The UE calculates the PF and PO based on the paging cycle T and the 5G-S temporary mobile subscriber identity (5G-S-TMSI). The formula is as follows:

[0191] PF: (SFN+PF_offset)mod T=(T div N)*(UE_ID mod N);

[0192] PO: i_s=floor(UE_ID / N)mod Ns

[0193] Among them, SFN is the system radio frame number; PF_offset is the radio frame offset value; mod means modulo; T is the paging cycle of the UE; div means division; N is the number of PFs in a paging cycle; UE_ID is 5G-S-TMSI mod 1024. If the UE does not have a 5G-S-TMSI, for example, when the UE has not yet registered with the network, the UE should use the default identifier UE_ID = 0 in the above PF and i_s formula; floor means rounding down; Ns is the number of POs associated with a PF; i_s is the logical sequence number of the PO in the PF.

[0194] For the UE, by calculating the PF, it can determine the system frame number of the received paging message, and then by calculating i_s, it can determine that its own PO is the i_s+1th PO in the PF. After determining the location of the PF and the specific PO, it can be known when the UE should wake up to receive the paging message, thereby initiating a service request (Service Request) to the network device that initiated the paging. Among them, the 5G-S-TMSI contains the AMF set identifier (AMF set ID), the AMF pointer (AMF pointer) and the 5G temporary mobile user identifier (5G-TMSI), which can identify a unique AMF within a certain AMF region (AMF Region).

[0195] However, the 6G architecture will be a new type of network architecture that integrates centralized mobile communication networks with the open internet, with centralized and distributed coexistence. It will need to move beyond centralized control and gradually evolve toward a distributed architecture, extending more networks to the network edge and establishing distributed, homogeneous micro-cloud units with varying functional levels, as shown in Figure 1. Each micro-cloud unit is self-contained and has complete control and data forwarding functions. Distributed network nodes are micro-cloud units deployed at the network edge, or the edge network.

[0196] In a 6G distributed network scenario, distributed network nodes are deployed on demand. Multiple distributed network nodes may be deployed within an AMF area. Under the current paging mechanism, the UE cannot distinguish the distributed network node that initiates the paging. Regarding how the UE distinguishes the paging source and determines the paging cycle and paging time in a 6G distributed network scenario, the present disclosure proposes a paging method in a 6G distributed network scenario.

[0197] FIG2 is a flow chart of a paging method provided by an embodiment of the present disclosure. As shown in FIG2 , the method includes:

[0198] S201. A distributed network node in a 6G distributed network sends a paging message to a user equipment UE, where the paging message includes an identifier of the distributed network node.

[0199] S202: The UE receives a paging message and initiates a service request to the target distributed network node based on the identifier of the distributed network node.

[0200] In the disclosed embodiment, each distributed network node in the 6G distributed network has a corresponding identifier (Network Node ID). For a distributed network node, it sends a paging message to a UE, and the paging message includes the identifier of the distributed network node. For a UE, it receives a paging message and determines which distributed network node the paging comes from based on the identifier of the distributed network node included in the paging message, and then initiates a service request to the distributed network node. The distributed network node receives the service request from the UE and performs subsequent processing. In this way, by carrying the identifier of the distributed network node in the paging message, the UE can distinguish the source of the paging in the 6G distributed network scenario.

[0201] For example, the target distributed network node sends a paging message to the UE, and the paging message carries the identifier of the target distributed network node. After receiving the paging message, the UE determines that the paging source is the target distributed network node based on the identifier of the target distributed network node carried in the paging message, and then initiates a service request to the target distributed network node. The target distributed network node receives the service request of the UE and performs subsequent processing.

[0202] In one implementation, the identifier of the distributed network node included in the paging message may be carried in a 6G-S temporary mobile user identity (6G-S-TMSI), that is, the paging message includes a 6G-S-TMSI, and the 6G-S-TMSI includes a distributed network node identifier. In one implementation, the 6G-S-TMSI may be obtained by expanding on the basis of the 5G-S-TMSI. As shown in FIG3 , a distributed network node identifier is added to the information contained in the 5G-S-TMSI. The 6G-S-TMSI includes a distributed network node identifier, an AMF set identifier, an AMF pointer, and a temporary mobile user identifier. When a UE first registers to the network, the distributed network node may allocate a 6G-S-TMSI to the UE. In subsequent paging processes, the 6G-S-TMSI may be carried in the paging message to distinguish the source of the paging.

[0203] On the basis of the above embodiment, the UE determines the paging frame and paging cycle in combination with the embodiment of FIG4. FIG4 is a flow chart of a paging method provided by an embodiment of the present disclosure. Referring to FIG4, the process involved is described as follows:

[0204] 1. The target distributed network node in the 6G distributed network sends a paging message to the Radio Access Network (RAN). The paging message includes the paging cycle and 6G-S-TMSI of the target distributed network node. The 6G-S-TMSI includes the identifier of the target distributed network node, the AMF set identifier, the AMF pointer and the temporary mobile user identifier.

[0205] The temporary mobile user identity refers to the temporary mobile user identity of the UE that the target distributed network node wants to page.

[0206] 2. The RAN receives the paging message and determines the paging frame and paging time of the target distributed network node based on the 6G-S-TMSI and the paging cycle of the UE in the target distributed network node. The paging cycle of the UE in the target distributed network node is determined based on the paging cycle of the target distributed network node and the UE-specific paging cycle.

[0207] The paging frame and paging time of the target distributed network node refer to the paging frame and paging time of the UE in the target distributed network node.

[0208] It should be noted that the embodiment of the present disclosure does not limit step 2 to be performed after step 1, that is, the step of RAN determining the paging frame and paging time may be performed before step 1.

[0209] 3. The RAN sends the paging message to the UE based on the paging frame and paging time of the target distributed network node.

[0210] 4. The UE determines the paging frame and paging time of the target distributed network node based on the paging cycle of the UE in the target distributed network node and the 6G-S-TMSI allocated by the target distributed network node to the UE. The 6G-S-TMSI includes the target distributed network node identifier, access mobility management function AMF set identifier, AMF pointer and temporary mobile user identifier.

[0211] It should be noted that the embodiment of the present disclosure does not limit step 4 to being performed after step 3, that is, the step of the UE determining the paging frame and the paging time may be performed before this step.

[0212] 5. The UE receives a paging message based on the paging frame and paging time of the target distributed network node.

[0213] 6. The UE initiates a service request (Service Request) to the target distributed network node based on the identifier of the target distributed network node in the paging message.

[0214] In the embodiment shown in FIG4 , the method for determining the paging frame and the paging time by the RAN and the UE is the same, specifically including:

[0215] A first value is obtained by dividing the paging cycle of the UE in the target distributed network node by the number of paging frames in one paging cycle, a second value is obtained by taking the modulus of the number of paging frames in one paging cycle by the user identifier, and a frame number of the paging frame is determined based on the product of the first value and the second value, wherein the user identifier is 6G-S-TMSI modulo 2048.

[0216] Divide the user ID by the number of paging frames in a paging cycle, round down the result, and then modulo the number of paging times associated with a paging frame to obtain the logical sequence number of the paging time in the paging frame.

[0217] That is, the following formula is used:

[0218] PF: (SFN+PF_offset)mod T=(T div N)*(UE_ID mod N);

[0219] PO: i_s=floor(UE_ID / N)mod Ns

[0220] Where SFN is the system radio frame number; PF_offset is the radio frame offset; mod represents modulo; T represents the paging cycle of the UE within the target distributed network node; div represents division; N represents the number of PFs in a paging cycle; UE_ID represents the user identifier (UE_ID is 6G-S-TMSI modulo 2048). If the UE does not have a 6G-S-TMSI, for example, when the UE has not yet registered with the network, the UE should use the default identifier UE_ID = 0 in the above PF and i_s formulas; floor represents rounding down; Ns represents the number of POs associated with a PF; i_s represents the logical sequence number of the PO within the PF. For the RAN and UE, the frame number of the PF and the logical sequence number i_s of the PO within the PF are calculated using the above formula, and the PO can be determined to be the i_s+1th PO within the PF.

[0221] The following further describes how to determine the paging cycle of the UE in the target distributed network node.

[0222] In one implementation, the UE sends a first NAS message to each distributed network node to which the UE is connected, where the first NAS message includes a UE-specific paging cycle; the UE receives a second NAS message, where the second NAS message includes an identifier and a paging cycle of the target distributed network node; the UE determines the minimum value between the UE-specific paging cycle and the paging cycle of the target distributed network node as the paging cycle of the UE in the target distributed network node.

[0223] The UE informs each connected distributed network node of its specific paging cycle through a first NAS message. If the distributed network node accepts the paging cycle, it carries the paging cycle when initiating paging. If one or more distributed network nodes do not accept the paging cycle, for example, if the target distributed network node does not accept the paging cycle, it is necessary to return a new paging cycle to the UE through a second NAS message, that is, the paging cycle of the target distributed network node, and carry the identifier of the target distributed network node. Based on the received second NAS message, the UE selects the paging cycle with the smallest paging cycle value from the UE-specific paging cycle and the paging cycle returned by the target distributed network node as the UE's paging cycle within the target distributed network node.

[0224] For the RAN, the UE-specific paging cycle is stored in the RAN. The RAN adopts the same rules as the UE to select the minimum value between the UE-specific paging cycle and the paging cycle returned by the target distributed network node as the paging cycle of the UE in the target distributed network node.

[0225] Optionally, the new paging cycle returned by the distributed network node to the UE may be determined by the distributed network node itself, or may be allocated to each distributed network node by the centralized network node in the 6G distributed network. The centralized network node may allocate different paging cycles to different distributed network nodes based on the activity area of ​​the UE, etc., and synchronize with the corresponding distributed network nodes, that is, the centralized network node sends the paging cycle of each distributed network node to each distributed network node of the 6G distributed network, and the distributed network node sends a synchronization response to the centralized network node. In the case where the distributed network node does not accept the UE-specific paging cycle, the paging cycle allocated to it by the centralized network node may be sent to the UE through a second NAS message.

[0226] In one implementation, the UE sends a first NAS message to each distributed network node to which the UE is connected, where the first NAS message includes a UE-specific paging cycle; the UE receives one or more second NAS messages, where each second NAS message includes an identifier and a paging cycle of each distributed network node; the UE determines the minimum value between the UE-specific paging cycle and the paging cycle of each distributed network node as the paging cycle of the UE in all distributed network nodes; and the UE sends the paging cycle of the UE in all distributed network nodes to the centralized network node of the 6G distributed network.

[0227] The UE informs each connected distributed network node of its specific paging cycle through a first NAS message. If the distributed network node accepts the paging cycle, the paging cycle is carried when initiating paging. If one or some distributed network nodes do not accept the paging cycle, a new paging cycle is returned to the UE through a second NAS message. The second NAS message sent by each distributed network node includes the paging cycle of the distributed network node, that is, the new paging cycle, and carries the identifier of the distributed network node. Based on the one or more second NAS messages received, the UE selects the paging cycle with the smallest paging cycle value from the UE-specific paging cycle and the paging cycle returned by the one or more distributed network nodes as the UE's paging cycle in all distributed network nodes, and sends the UE's paging cycle in all distributed network nodes to the centralized network node.

[0228] For the RAN, the UE-specific paging cycle is stored in the RAN. The RAN adopts the same rules as the UE to select the minimum value between the UE-specific paging cycle and the paging cycle returned by one or more distributed network nodes as the UE's paging cycle in all distributed network nodes.

[0229] Optionally, the new paging cycle returned by each distributed network node to the UE may be determined by the distributed network node itself, or may be allocated to each distributed network node by the centralized network node. The centralized network node allocates the same paging cycle to each distributed network node and synchronizes it with the corresponding distributed network node, that is, the centralized network node sends the paging cycle of each distributed network node to each distributed network node of the 6G distributed network, and the distributed network node sends a synchronization response to the centralized network node. In the case that one or more distributed network nodes do not accept the UE-specific paging cycle, the paging cycle allocated to them by the centralized network node is sent to the UE through a second NAS message, so that the UE selects the paging cycle with the smallest paging cycle value among the UE-specific paging cycle and the paging cycle returned by one or more distributed network nodes as the UE's paging cycle in all distributed network nodes.

[0230] In the embodiment of the present disclosure, the 6G-S-TMSI allocated by the distributed network node to the UE can be generated by the distributed network node, or can be generated by the centralized network node and then synchronized to the distributed network node.

[0231] In one implementation, the target distributed network node in the 6G distributed network generates a 6G-S-TMSI, which includes the identifier of the target distributed network node, the AMF set identifier, the AMF pointer and the temporary mobile user identifier, and synchronizes the 6G-S-TMSI to the centralized network node of the 6G distributed network; after the centralized network node receives the 6G-S-TMSI sent by the target distributed network node, it sends a synchronization response to the target distributed network node.

[0232] In one implementation, a centralized network node of a 6G distributed network generates a 6G-S temporary mobile user identity 6G-S-TMSI, which includes an identifier of a target distributed network node in the 6G distributed network, an access mobility management function AMF set identifier, an AMF pointer, and a temporary mobile user identity; sends the 6G-S-TMSI to the target distributed network node; the target distributed network node receives the 6G-S-TMSI sent by the centralized network node; and sends a synchronization response to the centralized network node.

[0233] The disclosed embodiments propose a paging method in a 6G distributed network scenario, reconstruct a paging identifier applicable to the 6G distributed network, and recalculate the paging frame and paging time based on the new paging identifier. At the same time, a method for determining the paging cycle of each distributed network node is clarified. This not only solves the problem of how the UE can distinguish which distributed network node the paging comes from in the 6G distributed network scenario, filling the current technical gap, but also satisfies the UE's need to reduce the number of monitoring times as much as possible, saving terminal power.
