With the development of wireless communication technology, especially the research of the fifth Generation mobile communication technology (5g, 5th Generation) has been developed, more and more terminals having different capabilities and different uses are appeared. A communication device (e.g., a core network device or an access network device) on the network side needs to know capability information of a terminal, so as to configure different resources according to different capability information of the terminal, perform transmission of communication data, and implement a communication function.

At present, the capability information of the network side device is acquired by adopting a mode of reporting the capability by the terminal. For example, the terminal reports its own capability information to the access network device during registration or registration update, and then the access network device sends the capability information of the terminal to the core network device for storage.

However, as the terminal supports more and more features, the capability information of the terminal becomes larger and larger, and then, the transmission of the capability information between the communication devices causes huge signaling overhead.

It should be noted that, at present, the capability information of the terminal is reported to the access network device during registration or registration update, and then the access network device sends the capability of the terminal to the core network device for storage. When the terminal initiates a connection establishment request, the access network device requests the core network device for the capability information of the terminal, and then provides configuration for the terminal according to the capability information of the terminal.

The embodiment of the application is provided for the process of transmitting the terminal capability information between the communication devices.

Based on the above description, the following embodiments are proposed.

Example one

An embodiment of the present application provides a data transmission method, which is applied to a core network device, and as shown in fig. 2, the method may include:

s101, acquiring terminal capability attribute information corresponding to the access network equipment.

And S102, sending the target terminal capability information corresponding to the terminal capability attribute information to the access network equipment.

In this embodiment of the present application, based on the architecture shown in fig. 1, in a process of performing communication between a terminal, an access network device, and a core network device, terminal capability information is required to be used for implementing a plurality of services or communication services.

In the core network device, the core network device stores all the capability information of the terminal, and the storage of the terminal capability information in the core network device is corresponding to the terminal capability attribute information, that is, the storage mode of the terminal capability information in the core network device is changed.

Based on the implementation, when the core network device obtains the terminal capability attribute information corresponding to the access network device, the core network device can find the target terminal capability attribute information matched with the terminal capability attribute information according to the terminal capability attribute information, and finally, the core network device sends the obtained target terminal capability information to the access network device as the core network device is correspondingly required by the access network device.

In some embodiments of the present application, the terminal capability attribute information includes at least one of:

the capability information of the PLMN to which the terminal belongs;

the terminal capacity information on a preset frequency band;

the terminal capacity information on the preset frequency band combination;

and (4) terminal type information.

It should be noted that, in the embodiment of the present application, not only the terminal capability attribute information listed above, but also the embodiment of the present application is not limited.

In some embodiments of the present application, a process of acquiring, by a core network device, terminal capability attribute information corresponding to an access network device may be actively acquired or may be passively acquired.

Passive acquisition: the core network equipment receives a terminal capacity request message sent by the access network equipment, wherein the terminal capacity request message carries terminal capacity attribute information.

It should be noted that the access network device needs to use the terminal capability information when performing resource configuration and control for the terminal, the access network device does not necessarily need the same terminal capability information each time, and when the terminal capability information needed by the access network device does not exist, the access network device requests the core network device to obtain the terminal capability information, that is, the access network device sends a terminal capability request message, where the terminal capability request message carries the terminal capability attribute information.

In this embodiment of the present application, the terminal capability request message sent by the access network device may be any message in a signaling interaction process performed by any access network device and core network device through a network interface, which is not limited in this embodiment of the present application.

Here, the access network device and the core network device communicate with each other through an S1 interface.

Active acquisition: the core network equipment acquires configuration information of the access network equipment; and acquiring terminal capability attribute information corresponding to the access network equipment according to the configuration information of the access network equipment.

It should be noted that, when a network is deployed, the core network device may obtain configuration information of an access network device communicating with the core network device, and therefore, the core network device may obtain terminal capability attribute information required by the access network device based on the obtained configuration information of the access network device.

It can be understood that, since the core network device transmits the terminal capability information according to the terminal capability attribute information, that is, the storage of the terminal capability information in the core network device is divided based on the terminal capability attribute information, when the terminal capability information is transmitted between network elements (that is, between communication devices), the terminal capability information corresponding to the terminal capability attribute information can be transmitted.

Further, in the data transmission method provided in the embodiment of the present application, as shown in fig. 3, between S101 and S102, the method further includes: s103; after S101, the method further comprises S104-S105. The following:

s103, acquiring target terminal capability information corresponding to the terminal capability attribute information from the preset capability information set.

In the embodiment of the application, the core network device stores the acquired terminal capability attribute information and terminal capability information of all the terminals in a preset capability information set. Then, after the core network device acquires the terminal capability attribute information corresponding to the access network device, the core network device may select the terminal target capability information from the capability information corresponding to the capability attribute information, which is stored in the preset capability information set.

In some embodiments of the present application, the preset capability information collectively stores terminal capability information obtained by dividing the source terminal capability information according to the capability attribute information.

In some embodiments of the present application, a terminal capability information set obtained by dividing the source terminal capability information according to the capability attribute information and a terminal capability identifier corresponding to the terminal capability information set are stored in the preset capability information set.

Here, the source terminal capability information is all terminal capability information of the terminal of the access network device server corresponding to the core network device. The source terminal capability information stored in the preset capability information set is configured in advance or acquired from the access network device, and the embodiment of the present application is not limited.

It should be noted that, in the embodiment of the present application, two storage manners are adopted for the preset capability information set, one may be directly in the form of a corresponding relationship between the capability attribute information and the capability information, and the other may be a corresponding relationship between the capability information set and the capability identifier, as well as between the capability attribute information and the capability identifier.

Illustratively, the saving of the specific capability attribute information and the terminal capability information may be as shown in table 1 below, where the capability attribute information is stored: PLMN 1, band 1+ band 2 (band combination information), and NB-IoT terminals (terminal type information), and corresponding terminal capability information.

TABLE 1

In the embodiment of the present application, the representation form of the terminal capability information may be directly displayed, or may be stored as a container.

Illustratively, based on the capability attribute information of table 1: PLMN 1, band 1+ band 2 (band combination information), and NB-IoT terminal (terminal type information), the expression form of its corresponding terminal capability information is: the displayed terminal is stored in the mode of the capability information of the frequency band 1, or the capability information of the frequency band 1 is stored as a container mode; the displayed terminal is stored in the mode of the capability information of the frequency band 1, or the capability information of the frequency band 1 is stored as a container mode; the method comprises the steps that the displayed capacity information of the terminal on the frequency band 1+ frequency band 2 is stored, or the capacity information on the frequency band 1+ frequency band 2 is stored as a container mode; and the displayed capability information of the terminal on the NB-IoT is stored, or the capability information on the NB-IoT is stored as a container. The embodiments of the present application are not limited.

And S104, acquiring a target terminal capability set corresponding to the terminal capability attribute information and a target terminal capability identifier corresponding to the target terminal capability set from the preset capability information set.

And S105, sending the target terminal capability set and the target terminal capability identifier to the access network equipment.

In this embodiment of the application, after the core network device acquires the terminal capability attribute information of the access network device, since the preset capability information set can store the terminal capability information set divided according to the capability attribute information and the terminal capability identifier corresponding to the terminal capability information set, the core network device can acquire the target terminal capability set corresponding to the terminal capability attribute information and the target terminal capability identifier corresponding to the target terminal capability set from the preset capability information set, and send the target terminal capability set and the target terminal capability identifier to the access network device.

It should be noted that, in this way, for the correspondence between the capability information set (referred to as terminal capability information set) and the capability identifier (referred to as terminal capability identifier) and the capability attribute information, the capability information supported by the terminal is stored in the manner of the capability information set, and for the specific capability attribute information, an index (i.e., capability identifier) is used. When the access network device needs the capability information corresponding to the specific capability attribute, the core network device sends the capability set corresponding to the capability attribute and the corresponding index identifier to the access network device.

In this embodiment of the present application, the correspondence between the terminal capability information set and the terminal capability identifier is, in detail, the terminal capability identifier is an identifier of each terminal capability information in the terminal capability information set, and the terminal capability identifier and each terminal capability information in the terminal capability information set may be one-to-one, one-to-many, many-to-many, or the like, which is not limited in this embodiment of the present application.

It should be noted that, in the embodiment of the present application, the terminal capability information set includes multiple pieces of terminal capability information, and the access network device finds the required capability information in such multiple pieces of information, which may be implemented by using the capability identifier as an index.

Illustratively, when the capability identifiers adopt consecutive integers as the labels, as shown in table 2, the PLMN 1 to PLMN N correspond to the capability identifiers 1 to N. The terminal capability identification may be one-to-one with each terminal capability information in the terminal capability information set. Each frequency band corresponds to a capability identifier. As shown in table 3, the frequency band combinations: the frequency band 1+ frequency band 2, up to the frequency band N-1+ frequency band N, corresponds to the capability identifier 1. The capability identifier N may be one-to-many with each terminal capability information in the terminal capability information set, and different frequency band combinations correspond to the same capability identifier. As shown in table 4, the frequency band 1-frequency band N corresponds to the capability identifier 1-M, where M is smaller than N. The capability identifier N may be many-to-many, and different frequency bands correspond to different capability identifiers, but the capability identifiers of at least two terminal capability information are the same.

TABLE 2

TABLE 3

Capability identification	Terminal capability information
		1	Frequency band 1+ frequency band 2
1	……
		1	Frequency band N-1+ frequency band N

TABLE 4

Capability identification	Terminal capability information
		1	Frequency band 1
……	……
		M, M is less than N	Frequency band N

It should be noted that, in the embodiment of the present application, the representation principles of the capability identifiers corresponding to all the terminal capability information sets are consistent, that is, the presentation forms of the capability identifiers are consistent, for example, 1-N arabic numbers are used as the capability identifiers, so that there are cases where the same capability identifier is used in different capability information sets.

It can be understood that, since the core network device transmits the terminal capability information set according to the terminal capability attribute information, that is, the storage of the terminal capability information set in the core network device is divided based on the terminal capability attribute information, when the terminal capability information set is transmitted between network elements (i.e., between communication devices), only the terminal capability information set corresponding to the terminal capability attribute information may be transmitted, so that, since only the required terminal capability information set is transmitted, even if all the terminal capability information is a lot, the pressure of the required terminal capability information set transmission performed between the communication devices is not increased, the required terminal capability information set is fixed, and on the contrary, the huge signaling overhead caused by the transmission of the capability information set between the communication devices is also reduced.

Example two

Based on the implementation of the first embodiment, an embodiment of the present application provides a data transmission method, which is applied to an access network device, and as shown in fig. 4, the method may include:

s201, receiving target terminal capability information corresponding to the terminal capability attribute information sent by the core network equipment.

And S202, providing configuration information for the target terminal according to the target terminal capability information.

In the embodiment of the application, when the access network performs resource configuration and control on the terminal, the terminal capability information corresponding to the terminal is needed to implement the resource configuration and control, and all the terminal capability information is stored in the core network device, so that when the access network device performs a service, the access network device can receive the target terminal capability information corresponding to the terminal capability attribute information from the core network device, and thus the access network device can provide configuration information for the target terminal according to the target terminal capability information, thereby implementing the service. The terminal capability information is stored in the core network device in such a way that the terminal capability attribute information corresponds to the terminal capability information.

the capability information of the PLMN to which the terminal belongs;

the terminal capacity information on a preset frequency band;

the terminal capacity information on the preset frequency band combination;

and (4) terminal type information.

It should be noted that, in this embodiment of the present application, the target terminal capability information may be obtained by the access network device sending a terminal capability request message to the core network device when needed, or may be obtained by the core network device actively obtaining, according to the obtained configuration information of the access network device, the target terminal capability information corresponding to the terminal capability attribute information and then directly sending the target terminal capability information to the access network device.

That is to say, for the access network device, before S201, the access network device may send a terminal capability request message to the core network device, where the terminal capability request message carries the terminal capability attribute information, and then the core network device finds the target terminal capability information from the preset capability information set according to the terminal capability attribute information, and sends the target terminal capability information to the access network device.

For example, the access network device and the core network device communicate with each other through an S1 interface.

For example, the access network device may carry the terminal capability request message in an initial UE message of the N2 interface, or carry the terminal capability request message in a message sent by any other access network to the core network.

In the embodiment of the present application, the core network device stores the acquired terminal capability attribute information and terminal capability information (i.e., source terminal capability information) of all terminals in a preset capability information set. Then, after the core network device acquires the terminal capability attribute information corresponding to the access network device, the core network device may select the terminal target capability information from the capability information corresponding to the capability attribute information, which is stored in the preset capability information set. The source terminal capability information may be preset to be stored in the core network device, or may be acquired from the terminal through the access network device.

Further, the transmission process of the source terminal capability information for one terminal is as follows: the access network equipment receives source terminal capability information at the beginning of network access, for example, when a terminal registers; and then, sending the source terminal capability information to the core network equipment for the core network equipment to use when obtaining the preset capability information set.

In some embodiments of the present application, the preset capability information set may also be obtained by dividing, by the access network device, source terminal capability information of different terminals according to the terminal capability attribute information, and then sending the divided source terminal capability information to the core network device for storage. The concrete implementation is as follows: after the access network equipment receives the source terminal capability information, the access network equipment can divide the source terminal capability information into terminal capability information according to the capability attribute information, and correspondingly store the capability attribute information and the terminal capability information as a preset capability information set; and sending a preset capability information set to the core network equipment. Or the access network equipment divides the source terminal capability information into a terminal capability information set according to the capability attribute information and sets a terminal capability identifier for the terminal capability set; correspondingly storing the capability attribute information, the terminal capability information and the terminal capability identification as a preset capability information set; and finally, sending the preset capability information set to the core network equipment.

It can be understood that, since the transmission of the terminal capability information corresponds to the terminal capability attribute information, and the terminal capability information is transmitted according to the terminal capability attribute information, when the terminal capability information is transmitted between network elements (i.e., between communication devices), the terminal capability information corresponding to the terminal capability attribute information may be transmitted, so that, since only the terminal capability information corresponding to a certain terminal capability attribute information is sent, even if all the terminal capability information is much, all the terminal capability information is fixed, when a service is implemented, transmitting the terminal capability information corresponding to a certain terminal capability attribute information corresponding to the service implementation does not increase the pressure of the terminal capability information transmission between the communication devices, but rather, the huge signaling overhead caused by the transmission of the capability information between the communication devices is also reduced.

Further, based on the above implementation, when the access network device performs handover, the transmission process of the terminal capability information is also involved. The access network device realized by the method is taken as a source access network device to explain data transmission when a scene is switched.

S203, in the process of switching to the target access network, acquiring the target terminal capability attribute information of the target access network.

And S204, acquiring final terminal capability information corresponding to the target terminal capability attribute information from the core network equipment according to the target terminal capability attribute information.

And S205, sending the target terminal capability attribute information and the final terminal capability information to the target access network equipment.

In this embodiment of the present application, in the process of switching from the source access network device to the target access network, the source access network device needs to send the terminal capability attribute information and the corresponding capability information required by the target access network to the target access network device. Therefore, the source access network device can acquire the target terminal capability attribute information of the target access network; and sending the target terminal capability attribute information to core network equipment, wherein the core network equipment acquires final terminal capability information corresponding to the target terminal capability attribute information from the preset capability information in a centralized manner, and then sends the target terminal capability attribute information and the final terminal capability information to the target access network equipment through the access network equipment.

It should be noted that, in this embodiment, both the source access network device and the target access network device communicate with the same core network device.

In some embodiments of the present application, the source access network device may obtain the target terminal capability attribute information of the target access network according to the configuration information of the target access network, or may request to obtain the target access network device. That is, the source access network device may obtain the terminal capability attribute information required by the target access network device based on the local configuration or obtain the terminal capability attribute information required by the target access network based on the request of the target access network device.

Specifically, the source access network device obtains configuration information of a target access network; and acquiring the target terminal capability attribute information of the target access network according to the configuration information of the target access network. Or, the source access network device receives a target capability information request sent by the target access network device, wherein the target capability information request carries the capability attribute information of the target terminal.

It can be understood that, since the core network device transmits the terminal capability information according to the terminal capability attribute information, that is, the storage of the terminal capability information in the core network device is divided based on the terminal capability attribute information, when the source access network device, the target access network device, and the source access network device and the core network device transmit the terminal capability information, the terminal capability information corresponding to the terminal capability attribute information may be transmitted.

EXAMPLE III

Based on the implementation of the first embodiment and the second embodiment, an exemplary embodiment of the present application provides a data transmission method, as shown in fig. 5, including:

s301, when at least one terminal is registered, sending source terminal capability information to the access network equipment.

S302, the access network equipment sends the source terminal capability information to the core network equipment.

S303, the core network device divides the source terminal capability information into terminal capability information according to the capability attribute information and stores the terminal capability information as a preset capability information set.

S304, when the access network equipment configures at least one terminal, the access network equipment sends a terminal capacity request message to the core network equipment, wherein the terminal capacity request message carries terminal capacity attribute information.

S305, the core network equipment acquires target terminal capability information corresponding to the terminal capability attribute information from the preset capability information set.

S306, the core network equipment sends the target terminal capability information corresponding to the terminal capability attribute information to the access network equipment.

And S307, the access network equipment provides configuration information for at least one terminal according to the target terminal capability information.

In some embodiments of the present application, data related to terminal capability information needs to be transmitted between the access network device, the core network device, and the terminal, but in this transmission process, because these are implemented in the inter-network element interface message transmission process, and the inter-network element interface message has a bearer capability limitation, a factor of a maximum bearer capability of the inter-network element interface message also needs to be considered in the data transmission process.

The transmission of the data related to the terminal capability information between any two network elements in the access network device, the core network device and the terminal is simplified into the data transmission between the sending end and the receiving end. The correspondence between the transmitting end and the receiving end is shown in table 5.

It should be noted that, in the embodiment of the present application, the terminal capability information related data sent by the core network device to the access network device is target terminal capability information; the method comprises the steps that terminal capacity information related data sent to core network equipment by access network equipment are source terminal capacity information; the terminal capability information related data sent by the terminal to the access network equipment is source terminal capability information; and the terminal capacity information related data sent by the source access network equipment to the target access network equipment is final terminal capacity information. The specific process is as follows:

the sending end determines whether the terminal capability information related data meets the preset network element interface message bearing condition or not; when the preset network element interface message bearing condition is not met, the sending end splits the terminal capacity information related data according to the preset network element interface message bearing condition, and N sub-terminal capacity information related data are obtained; wherein N is an integer greater than or equal to 1; and respectively sending the N pieces of data related to the sub-terminal capability information to a receiving end.

In the embodiment of the present application, if the size of the data related to the terminal capability information exceeds the maximum bearer capability of the interface message between the network elements, the sender may divide the data related to the terminal capability information into a plurality of messages to be sent.

The preset network element interface message bearing condition is the network element interface message bearing capacity.

Illustratively, if the maximum bearing capacity of the interface message between the network elements between the sending end and the receiving end is Xbit and the terminal capacity information related data is Ybit, the sending end may be divided into Y/X +1 messages to send the sub-terminal capacity information related data.

It should be noted that, in the embodiment of the present application, on the premise that the data related to the capability information of the sub terminal meets the preset message bearing condition of the network element interface, the splitting manner is not limited.

It can be understood that, when the sending end transmits the terminal capability related data, the factor of the bearing capability of the interface between the network elements is considered, and the success rate of sending the sub-terminal capability information related data is ensured, so that the success rate of receiving the terminal capability related data by the receiving end is improved, and the transmission pressure between the network elements is also reduced.

In the embodiment of the application, the sending end needs to inform the message receiving end about the information of the message segments when the sending end carries out the message, so that the sending end can be conveniently used when the segmented messages are integrated.

In some embodiments of the application, a sending end carries out segmentation marking on N pieces of sub-terminal capability information related data to obtain marking information of each piece of sub-terminal capability information related data, wherein the marking information is used for representing segmentation positions and total number of segments where the sub-terminal capability information related data are located; and the sending end respectively sends the mark information of the capacity information related data of each sub-terminal and the capacity information related data of each sub-terminal to the receiving end.

In this embodiment, the receiving end may determine whether the data transmission is finished according to the mark information of the data related to the capability information of each sub-terminal, and when the data transmission is finished, arrange the data related to the capability information of the N sub-terminals according to the segment position in the mark information, and integrate the data related to the capability information of one terminal.

It should be noted that, the segment position of the data related to the sub-terminal capability information may be the information related to the second segment, and may further include an identifier that is the last segment, so as to determine whether the data transmission is finished. The data related to the sub-terminal capability information may be carried in a segmented message for transmission.

Based on the consideration of segmentation, after receiving the data related to the capability information of multiple sub-terminals, the receiving end needs to integrate the data related to the capability information of multiple sub-terminals, and then the data needs to be integrated according to the segmentation position.

In some embodiments of the application, a sending end associates the capability information related data of the N sub-terminals to obtain an association label of the capability information related data of each sub-terminal, wherein the association label is used for representing that the capability information related data of the sub-terminals belong to the same terminal capability information related data; and the sending end respectively sends the related data of each sub-terminal capability information and the associated marks of the related data of each sub-terminal capability information to the receiving end.

In this embodiment, the receiving end may determine whether the data is transmitted by the same transmitting end according to the association flag, and integrate the data related to the N sub-terminal capability information transmitted by the same transmitting end.

That is, the sender carries the number of segments of the message in the segmented message and the current message is the second segment; the receiving end can be associated to the segmented data of the same message through the association identification. The sending end carries whether the current message has a subsequent segmented message or not in the segmented message or carries a mark whether the current message is the last segmented message or not.

Illustratively, the segmented message, the tag information, and the association identifier may be as shown in table 6. In table 6, segment message 1 carries segment data 1, and the segment location is segment 1. The segmentation message 1 carries segment data 2, and the segmentation position is the 2 nd segment; the segment message 3 carries segment data 3, the segment position is the 3 rd segment, and the associated identifiers of the segment data are all 1, the representation is that the same data is divided into 3 segments, and the total number of the segments is 3.

TABLE 6

Segmented messages	Marking information	Association identifier
			Segmented message 1	Total number of segments 3, 1 st segment	1
Segmented message 2	Total number of segments 3, 2 nd segment	1
			Segmented message 3	Total number of segments 3, 3 rd segment	1

It can be understood that, when the sending end and the receiving end transmit data related to the capability information of the N sub-terminals, the timing sequence and the classification of data transmission are considered, so that the problem of data integration errors is avoided, and the accuracy of data transmission is improved.
