Description

Technical Field

[0001] The present application relates to the field of wireless communications, and in particular to an information transmission method, apparatus, related equipment, and storage medium. Background Art

[0002] When a service needs to call an inactive terminal, the network side will initiate paging to the terminal. In related technologies, a terminal can only reside in one cell, namely the serving cell, to receive paging messages from the serving cell. In other words, the slice (which can be expressed as slice in English) service that the terminal can obtain in the serving cell must be a subset of the slices supported by the serving cell. Therefore, even if the network slice of the neighboring cell (same-frequency neighboring cell or different-frequency neighboring cell) is a slice supported by the terminal, the terminal in the inactive state can only reside in the serving cell, so the terminal cannot receive the paging message of the neighboring cell slice, which results in the terminal being unable to obtain the service of the neighboring cell slice.

[0069] The present application will be described in further detail below with reference to the accompanying drawings and embodiments.

[0070] The network side sends a paging message at the paging frame (PF) / paging time (PO) of the paging, and the paging message carries the UE ID.

[0071] Since the terminal in inactive state can only reside in one cell and receive the paging message of this cell. If the slices supported by the current cell and the neighboring cell are different, the terminal cannot receive the paging message of the neighboring cell slice, which will cause the adjacent frequency or adjacent cell slice to be unreachable. For example, Figure 1As shown, the terminal is in area 1 (Area 1), Area 1 includes cell 1 (cell 1) (frequency F2) and cell 2 (cell 2) (frequency F1), the terminal initiates access in cell 2, and the terminal reports the UE capabilities to the network side. Assuming that the terminal supports slice 1 and 2, the slice request sent by the terminal to the network side (i.e., the requested single network slice selection auxiliary information (requested S-NSSAI)) will include slice 1 and slice 2. According to the provisions of the relevant technology, the terminal resides in cell 2, and cell 2 only supports slice 1, so the allowed S-NSSAI (allowed S-NSSAI) sent by the network side to the terminal only includes slice 1. In other words, if the slices supported by the current cell are different from those supported by the neighboring cell or adjacent frequency, the terminal cannot receive the paging message of the neighboring cell or adjacent frequency slice. Therefore, when the terminal has the ability to support multiple slices simultaneously in different cells or at different frequencies, how to receive paging messages from neighboring slices in the inactive state and obtain the services of neighboring slices is an urgent problem to be solved.

[0072] Based on this, in various embodiments of the present application, the terminal has a new capability, which means that the terminal can support multiple slices at the same time in different cells or frequencies. Among them, for terminals that do not support the new capability, they can only access the slice of one cell, while for terminals that support the new capability, they can access multiple cells at the same time to obtain multiple different slice services, such as accessing multiple cells at the same time through CA or multiple connections (such as dual connection (DC)), so that they can obtain services of multiple different slices at the same time, that is, the terminal can access slices of different cells at the same time through CA or multiple connections. At the same time, when the terminal enters the inactive state, the base station of the current serving cell and the base stations of other neighboring cells retain the context of the terminal, so that the base station of the current serving cell and the base stations of other neighboring cells can have the ability to page the terminal, so that the terminal in the inactive state can obtain services of slices of different cells or frequencies at the same time, and can receive paging messages of different slices.

[0073] The embodiment of the present application provides an information transmission method, which is applied to a first access network device, such as Figure 2 As shown, the method includes:

[0074] Step 201: Send a connection release message to the terminal;

[0075] Step 202: Send at least one of the following information to at least one second access network device:

[0076] first information indicating a RAN notification area configuration of the terminal;

[0077] second information, where the second information instructs the second access network device to disconnect from the terminal;

[0078] Third information: The third information indicates the identification of the terminal.

[0079] That is, information enabling the second access network to have a paging terminal capability is sent to the second access network device.

[0080] The access network device may specifically be a base station.

[0081] In actual application, in order to implement the solution of the embodiment of the present application, the terminal needs to support at least two network slices at the same time in at least two cells or frequencies, that is, the terminal can obtain services of at least two slices at the same time through at least two access network devices.

[0082] Therefore, when the network side configures the allowed slices for the terminal, that is, when configuring allowed S-NSSAI, if a slice is not supported by the current cell but the neighboring cell can provide the service of the slice through CA or multi-connection mode, the slice can be configured as the allowed slice of the terminal. Figure 1 In the scenario shown, the terminal is in serving cell 2, which only supports slice 1, while cell 1 supports slice 2. The network configures the terminal with allowed slices that include both slices 1 and 2. In this scenario, the terminal supports simultaneous access to slices 1 and 2 through dual connectivity or call access (CA). This means that when the terminal is in cell 2 and initiates a service for slice 2, it can access cell 2 and establish a DC or CA with cell 1, allowing the terminal to receive services from both slices 1 and 2.

[0083] Based on this, in one embodiment, the method may further include:

[0084] The allowed network slice information is sent to the terminal; the allowed network slice includes the first network slice; the first access network device does not support the first network slice; the second access network device supports the first network slice; the terminal can access the second access network device through CA or multi-connection mode.

[0085] Here, it should be noted that: in the embodiment of the present application, the at least two slices allowed by the terminal need to be obtained from at least two cells, that is, the at least two slices allowed by the terminal cannot be obtained through one cell.

[0086] In an embodiment of the present application, when the terminal simultaneously accesses slices of different cells through CA or multi-connection mode, one cell is the main cell and the other cells are secondary cells, that is, the first access network device is the main base station (also called the main node), and the second access network device is the secondary base station (also called the secondary node).

[0087] When the terminal enters the inactive state, the first access network device sends a connection release message to the terminal. The connection release message carries a RAN notification area configuration, which includes a number of cells or tracking areas. At this point, the first access network device saves the terminal's context. After receiving the connection release message, the terminal also saves the terminal's context.

[0088] In actual application, steps 201 and 202 are executed in no particular order. Specifically, step 201 may be executed first, and then step 202, or step 202 may be executed first, and then step 201, or step 201 and step 202 may be executed simultaneously.

[0089] The first access network device sends the above information through the interface between the first access network device and the second access network device (such as an Xn or X2 interface, etc.). The three information can be carried in one message (i.e., one signaling) and sent, or carried in different messages and sent through multiple messages. This embodiment of the present application is not limited to this. In actual application, the message carrying the above information can be a secondary node release request (S-NODE RELEASE REQUEST) message, or a secondary node modification request (S-NODE MODIFICATION REQUEST) message, etc.

[0090] The first information is used by the secondary node to send a RAN paging message containing the terminal identifier (e.g., terminal ID) so that the corresponding slice can reach the terminal. The first access network device also saves the RAN notification area configuration of the terminal so that after the terminal downlinks data, it can initiate a RAN paging message containing the terminal identifier (e.g., resume ID) based on the RAN notification area configuration.

[0091] The second information is specifically used to instruct the auxiliary node to suspend the connection with the terminal, and can also be understood as an instruction to save the context of the terminal, and can also be understood as saving the connection with the core network (can also be understood as maintaining the connection with the core network), that is, the second access network device suspends the connection with the terminal according to the second information, saves the context of the terminal, and saves the connection with the core network.

[0092] Based on this, in one embodiment, the second information indicates at least one of the following:

[0093] instructing the second access network device to suspend the connection with the terminal;

[0094] instructing the second access network device to save the context of the terminal;

[0095] Instruct the second access network device to save the connection with the core network.

[0096] The third information may specifically be a terminal ID and / or shortMAC-I. The terminal ID is used to identify the terminal and may be a resume ID. The shortMAC-I is used to identify or securely verify the terminal.

[0097] For example, the terminal can support multiple slices simultaneously in two different cells or frequencies; Figure 3 As shown in Figure 1, when the terminal obtains services of two slices through two base stations respectively, the terminal accesses the two base stations through DC, where base station A is the primary node and base station B is the secondary node. The anchor point of the terminal in the inactive state may be in one base station or in multiple base stations. Figure 3 As shown, after the terminal enters the inactive state from the connected state, it needs to maintain the connection with the core network and disconnect the connection with the terminal.

[0098] At this time, base station A sends a connection release message to the terminal, and carries a RAN notification area configuration in the message, where the RAN notification area configuration includes several cells or tracking areas.

[0099] Base station A sends at least one of the following information to base station B:

[0100] First information;

[0101] Second information;

[0102] Third information.

[0103] Base station A serves as the master node and is the anchor point for controlling the anchor point and slice 1. Base station A suspends the connection with the terminal, saves the context of the terminal, and maintains the connection with the core network.

[0104] Base station B is the anchor point of slice 2; after receiving the information, base station B suspends the connection with the terminal, saves the terminal context, and maintains the connection with the core network. Since the terminal information (including context and / or terminal identification) is saved, base station B has the ability to page the terminal, and the terminal in the inactive state can also receive information from slice 2, making slice 2 online.

[0105] At the same time, after receiving the message, the terminal saves the context and enters the inactive state.

[0106] The connections between the terminal and the two base stations are suspended, and the primary and secondary base stations save the terminal context.

[0107] Since both the primary node and the secondary node, i.e., the first access network device and the second access network device, store the RAN notification area configuration of the terminal, both can initiate RAN paging. In addition, since the first access network device and the second access network device store the terminal information, including at least one of the context and the identifier, both the primary node and the secondary node have the ability to page the terminal.

[0108] For a terminal in the inactive state, it only needs to request to receive a paging message from the serving cell. After receiving the paging message, the terminal will initiate a connection request to restore the connection with the primary node and / or the secondary node.

[0109] In actual application, the terminal can report its own capabilities so that the network side can know whether the at least two slices allowed by the terminal need to be obtained from at least two cells or frequencies.

[0110] Based on this, in one embodiment, the method may further include:

[0111] Receive the capability reported by the terminal; the capability indicates whether the at least two slices allowed by the terminal need to be obtained from at least two cells or frequencies.

[0112] That is to say, the capability represents whether the terminal supports at least two network slices simultaneously in at least two cells or frequencies.

[0113] When the terminal supports it, the reported capability indicates that the terminal supports at least two network slices simultaneously in at least two cells or frequencies.

[0114] Among them, if the terminal does not support the above capabilities, even if the terminal reports multiple supported slices, the allowed slices configured by the network side still only include the slices supported by the serving cell. Figure 1 In the scenario shown, the terminal is in the serving cell 2. If the terminal supports the above capabilities, the terminal reports to the network side that the supported slices include slice 1 and slice 2, and the allowed slices configured by the network side include slice 1 and slice 2. If the terminal does not support the above capabilities, although the terminal network side reports that the supported slices include slice 1 and slice 2, the allowed slices configured by the network side only include slice 1.

[0115] In actual application, when the terminal does not report the above capabilities, the network side will consider that the terminal does not have the above capabilities, and the allowed slices configured by the network side will still only include the slices supported by the serving cell.

[0116] When receiving downlink data (ie, data sent to the terminal), the first access network device may initiate RAN paging to the terminal using the RAN notification area configuration information.

[0117] Accordingly, an embodiment of the present application further provides an information transmission method, which is applied to a second access network device, including:

[0118] Receive at least one of the following information sent by the first access network device:

[0119] first information indicating a RAN notification area configuration of the terminal;

[0120] second information, where the second information instructs the at least one second access network device to disconnect from the terminal;

[0121] Third information: The third information indicates the identification of the terminal.

[0122] In one embodiment, when the first information is received, that is, when downlink data is received in the case of receiving the first information, RAN paging is initiated to the terminal using the RAN notification area configuration information. Specifically, a paging message including a terminal identifier is sent, and a paging message of the terminal is sent to other access network devices within the RAN notification area via an interface between access network devices, thereby triggering the access network devices within the RAN notification area to send a paging message including the terminal identifier.

[0123] When the second information is received, that is, when the second information is received, the second access network device suspends the connection with the terminal according to the second information, saves the context of the terminal, and saves the connection with the core network so as to be able to page the terminal in the inactive state.

[0124] When the third information is received, that is, in the case of receiving the third information, the second access network device saves the terminal identifier so as to page the terminal in the inactive state using the third information.

[0125] When the first information is not received, the second access network device may initiate paging to the terminal based on default notification area configuration (such as tracking area configuration) information.

[0126] The present application also provides an information transmission method, such as Figure 4 As shown, the method includes:

[0127] Step 401: The first access network device sends a connection release message to the terminal;

[0128] Step 402: The first access network device sends information to at least one second access network device that enables the second access network device to have a paging terminal capability;

[0129] That is, the second access network device sends at least one of the following information:

[0130] first information indicating a RAN notification area configuration of the terminal;

[0131] second information, where the second information instructs the second access network device to disconnect from the terminal;

[0132] Third information; the third information indicates the identifier of the terminal;

[0133] Step 403: The second access network device receives the information sent by the first access network device.

[0134] It should be noted that the specific processing procedures of the first access network device and the second access network device have been described in detail above and will not be repeated here.

[0135] The information transmission method provided by the embodiment of the present application is as follows: a first access network device sends a connection release message to a terminal; and sends at least one of the following information to at least one second access network device: first information, the first information indicating the RAN notification area configuration of the terminal; second information, the second information indicating that the second access network device disconnects from the terminal; third information; the third information indicates the identification of the terminal; the second access network device receives the information sent by the first access network device; the solution provided by the embodiment of the present application, in the process of the terminal entering the inactive state, since information is sent to the auxiliary node so that the auxiliary node also has the ability to page the terminal, the main node and the auxiliary node both have the ability to page the terminal, so that the terminal in the inactive state can obtain services of slices of different cells or frequencies at the same time, and can receive paging messages of different slices.

[0136] In order to implement the method of the embodiment of the present application, the embodiment of the present application further provides an information transmission device, which is set on the first access network device, such as Figure 5 As shown, the device includes:

[0137] The first sending unit 501 is configured to send a connection release message to a terminal;

[0144] In one embodiment, the apparatus may further include:

[0145] The first paging unit is configured to initiate RAN paging to the terminal by using the RAN notification area configuration information when receiving downlink data.

[0157] Wherein, when the first information is not received, the second paging unit is further configured to initiate paging to the terminal based on default notification area configuration (such as tracking area configuration) information.

[0158] In actual application, the first receiving unit 601 can be implemented by a communication interface in the information transmission device; the processing unit 602 and the second paging unit can be implemented by a processor in the information transmission device in combination with the communication interface.

[0159] It should be noted that the information transmission device provided in the above embodiments is illustrated only by the division of the aforementioned program modules when performing information transmission. In actual applications, the aforementioned processing can be assigned to different program modules as needed, that is, the internal structure of the device can be divided into different program modules to complete all or part of the aforementioned processing. In addition, the information transmission device provided in the above embodiments and the information transmission method embodiment are based on the same concept. The specific implementation process is detailed in the method embodiment and will not be repeated here.

[0160] Based on the hardware implementation of the above program modules, and in order to implement the method of the first access network device side of the embodiment of the present application, the embodiment of the present application also provides a first access network device, such as Figure 7 As shown, the first access network device 700 includes:
