Communication equipment on the network side (for example, core network equipment or access network equipment, etc.) needs to know the capability information of the terminal, so as to configure different resources according to different capability information of the terminal, transmit communication data, and realize communication functions.

At present, the acquisition of the capability information of the network-side device is realized by means of reporting 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 terminal's capability information to the core network device for storage. In this way, when a terminal initiates a communication connection establishment request, the access network device will request the terminal's capability information from the core network device, and then provide configuration for the terminal according to the terminal's capability information to realize the transmission of communication data with the terminal.

However, as the terminal supports more and more features, the capability information of the terminal will become larger and larger, so the transmission of the capability information between communication devices will bring huge signaling overhead.

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

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

Embodiment one

The embodiment of the present application provides a data transmission method, which is applied to core network equipment. As shown in FIG. 2, the method may include:

S101. Acquire terminal capability attribute information corresponding to an access network device.

S102. Send target terminal capability information corresponding to the terminal capability attribute information to the access network device.

In the embodiment of this application, based on the architecture shown in Figure 1, during the communication process between the terminal, the access network device and the core network device, the realization of many services or communication services requires the use of terminal capability information, based on this requirement , the embodiment of the present application provides a processing procedure for terminal capability information transmission.

In the core network device, all capability information of the terminal is stored in the core network device, and the storage of the terminal capability information in the core network device corresponds to the terminal capability attribute information, that is to say, the terminal capability information in the core network device The storage method has changed.

Based on the above implementation, when the core network device obtains the terminal capability attribute information corresponding to the access network device, then the core network can find the target terminal capability attribute information that matches the terminal capability attribute information according to the terminal capability attribute information , and finally, because it is required by the access network device, the core network device sends the obtained target terminal capability information to the access network device.

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

Capability information of the PLMN to which the terminal belongs;

Capability information of the terminal on the preset frequency band;

Capability information of the terminal on the preset frequency band combination;

Terminal type information.

It should be noted that, the embodiment of the present application may not only include the terminal capability attribute information listed above, and the embodiment of the present application does not limit it.

In some embodiments of the present application, the process for the core network equipment to acquire the terminal capability attribute information corresponding to the access network equipment may be acquired actively or passively.

Passive acquisition: The core network device receives the terminal capability request message sent by the access network device, and the terminal capability request message carries terminal capability attribute information.

It should be noted that the access network device needs to use the terminal capability information when configuring and controlling resources for the terminal, and the access network device does not necessarily need the same terminal capability information every time, when the access network device needs If the terminal capability information does not exist, it requests the core network device to obtain it, that is, the access network device sends a terminal capability request message, and the terminal capability request message carries terminal capability attribute information.

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

Here, the communication between the access network device and the core network device is performed through the S1 interface.

Active acquisition: The core network device obtains the configuration information of the access network device; according to the configuration information of the access network device, obtains the terminal capability attribute information corresponding to the access network device.

It should be noted that during network deployment, the core network device can obtain the configuration information of the access network device communicating with it. Therefore, the core network device can learn the configuration information of an access network device based on the acquired The terminal capability attribute information required by the access network device.

It can be understood that since the core network equipment 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 equipment is divided based on the terminal capability attribute information, then, between network elements When transmitting terminal capability information (that is, between communication devices), the terminal capability information corresponding to the terminal capability attribute information can be transmitted. In this way, since only the required terminal capability information is sent, even if all the terminal capability information is It will not increase the pressure on the transmission of required terminal capability information between communication devices, but will reduce the huge signaling overhead caused by the transmission of capability information between communication devices.

Further, in the data transmission method provided by the embodiment of the present application, as shown in FIG. 3 , between S101 and S102, the above method further includes: S103; after S101, the method further includes S104-S105. as follows:

S103. Acquire target terminal capability information corresponding to the terminal capability attribute information from the preset capability information set.

In the embodiment of the present application, the core network device stores the acquired terminal capability attribute information and terminal capability information of all terminals in the preset capability information set. Then, after the core network device obtains the terminal capability attribute information corresponding to the access network device, the core network device can select the terminal target capability information from the capability information corresponding to the capability attribute information stored in the preset capability information set .

In some embodiments of the present application, the preset capability information centrally stores terminal capability information that divides source terminal capability information according to capability attribute information.

In some embodiments of the present application, the preset capability information set stores terminal capability information sets that divide source terminal capability information according to capability attribute information, and terminal capability identifiers corresponding to the terminal capability information sets.

Here, the source terminal capability information is all terminal capability information of terminals served by the access network device corresponding to the core network device. Wherein, the source terminal capability information stored in the preset capability information set is pre-configured or obtained from an access network device, which is not limited in this embodiment of the present application.

It should be noted that in the embodiment of this application, the preset capability information set adopts two storage methods, one can be directly in the form of the corresponding relationship between capability attribute information and capability information, and the other can be in the form of capability information set and Capability identifier, and the corresponding relationship of capability attribute information.

Exemplarily, the storage of specific capability attribute information and terminal capability information can be shown in Table 1 below, which stores capability attribute information: PLMN 1, frequency band 1, frequency band 1+frequency band 2 (frequency band combination information), and NB-IoT terminal (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.

Exemplary, based on the capability attribute information in Table 1: PLMN 1, frequency band 1, frequency band 1+frequency band 2 (frequency band combination information), and NB-IoT terminal (terminal type information), the corresponding terminal capability information is represented as : The displayed terminal is saved as the capability information of frequency band 1, or the capability information of frequency band 1 is stored as a container; the displayed terminal is saved as the capability information of frequency band 1, or the capability information of frequency band 1 is stored as a container ;The displayed terminal capability information on frequency band 1+frequency band 2 is saved, or the capability information on frequency band 1+frequency band 2 is stored as a container; the displayed terminal capability information on NB-IoT is saved, Or the capability information on NB-IoT is stored as a container. The embodiment of this application is not limited.

S104. Obtain 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.

S105. Send the target terminal capability set and the target terminal capability identifier to the access network device.

In the embodiment of the present application, after the core network device obtains 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 information set corresponding to The terminal capability identifier, therefore, the core network device can obtain 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 combine the target terminal capability set and the target The terminal capability identifier is sent to the access network device.

It should be noted that, for the capability information set (referring to the terminal capability information set), the capability identifier (referring to the terminal capability identifier), and the corresponding relationship between capability attribute information, the capability information supported by the terminal is saved in the form of capability information set , using an index (namely, capability identification) method for specific capability attribute information. When the access network device needs capability information corresponding to a specific capability attribute, the core network device only needs to send the capability set corresponding to the capability attribute and the corresponding index identifier to the access network device.

In this embodiment of the application, the correspondence between the terminal capability information set and the terminal capability identifier, in detail, the terminal capability identifier is the identifier of each terminal capability information in the terminal capability information set, and the terminal capability identifier and each terminal in the terminal capability information set The capability information may be one-to-one, one-to-many, or many-to-many, 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 contains multiple terminal capability information, so the access network device may need to use the capability identifier as an index to find the required capability information among so many pieces of information. .

Exemplarily, when the capability identifier adopts consecutive integers as marks, as shown in Table 2, PLMN 1-PLMN N corresponds to the capability identifier 1-N capability identifier N. There may be a one-to-one relationship between the terminal capability identifier and each terminal capability information in the terminal capability information set. Each frequency band corresponds to a capability identifier. As shown in Table 3, frequency band combinations: frequency band 1+frequency band 2, up to frequency band N-1+frequency band N all correspond to capability identifier 1. The capability identifier N terminal capability identifier and each terminal capability information in the terminal capability information set may be one-to-many, and different frequency band combinations correspond to the same capability identifier. As shown in Table 4, frequency band 1-frequency band N corresponds to capability identifier 1-M, and M is smaller than N. Capability identifier N The terminal capability identifier and each terminal capability information in the terminal capability information set may be many-to-many, different frequency bands correspond to different capability identifiers, but there are at least two terminal capability information with the same capability identifier.

Table 2

table 3

Capability ID Terminal Capability Information 1 Band 1+ Band 2 1 ... 1 Band N-1+ Band N

Table 4

Capability ID Terminal Capability Information 1 Band 1 ... ... M, M is less than N Band N

It should be noted that, in this embodiment of the application, the expression principles of the capability identifiers corresponding to all terminal capability information sets are consistent, that is, the presentation forms of the capability identifiers are consistent. For example, 1-N Arabic numerals are used as the capability identifiers. In this case , there is a situation 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, then, in When the terminal capability information set is transmitted between network elements (that is, between communication devices), only the terminal capability information set corresponding to the terminal capability attribute information can be transmitted. In this way, since only the required terminal capability information set is sent, even All the terminal capability information is a lot, and it will not increase the pressure on the transmission of the required terminal capability information set between communication devices. The required terminal capability information set is fixed, but it also reduces the capability information set in the communication device. The transmission between them will bring huge signaling overhead.

Embodiment two

Based on the implementation of Embodiment 1, this embodiment of the present application provides a data transmission method, which is applied to an access network device. As shown in FIG. 4, the method may include:

S201. Receive target terminal capability information corresponding to terminal capability attribute information sent by a core network device.

S202. Provide configuration information for the target terminal according to the capability information of the target terminal.

In this embodiment of the application, when the access network configures and controls resources for a terminal, it needs the terminal capability information corresponding to the terminal to implement, and all terminal capability information is stored in the core network equipment, then the access network equipment in the When performing services, the target terminal capability information corresponding to the terminal capability attribute information can be received from the core network device, so that the access network device can provide configuration information for the target terminal according to the target terminal capability information to realize services. Wherein, 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.

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

Capability information of the PLMN to which the terminal belongs;

Capability information of the terminal on the preset frequency band;

Capability information of the terminal on the preset frequency band combination;

Terminal type information.

It should be noted that, the embodiment of the present application may not only include the terminal capability attribute information listed above, and the embodiment of the present application does not limit it.

It should be noted that, in this embodiment of the 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 by the core network device according to the obtained The configuration information of the access network device is actively obtained according to the configuration information, and the target terminal capability information corresponding to the terminal capability attribute information is obtained, and then directly sent to the access network device.

That is to say, for an access network device, before S201, the access network device can send a terminal capability request message to the core network device, and the terminal capability request message carries terminal capability attribute information, so the core network device can send a terminal capability request message according to the terminal capability attribute information. The capability attribute information is to find the target terminal capability information from the preset capability information set and send it to the access network device.

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

For example, the access network device and the core network device communicate through the S1 interface.

For example, the access network device may carry the terminal capability request message in the initial UE message on the N2 interface, or carry the terminal capability request message in any other message sent from the 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 (ie source terminal capability information) of all terminals in the preset capability information set. Then, after the core network device obtains the terminal capability attribute information corresponding to the access network device, the core network device can select the terminal target capability information from the capability information corresponding to the capability attribute information stored in the preset capability information set . The capability information of the source terminal may be pre-set and stored in the core network device, or may be obtained from the terminal by accessing the network device.

Further, the transmission process of the source terminal capability information for a terminal is as follows: the access network device receives the source terminal capability information at the beginning of network access, for example, when the terminal registers; then, the source terminal capability information is sent to the core network device for the core network It is used when the network device obtains the preset capability information set.

In some embodiments of the present application, the preset capability information set may also be obtained by the access network device after dividing the source terminal capability information of different terminals according to the terminal capability attribute information, and then send it to the core network device for storage. The specific implementation is: after the access network device receives the source terminal capability information, the access network device can divide the source terminal capability information into terminal capability information according to the capability attribute information, and store the capability attribute information and the terminal capability information correspondingly as a preset Setting the capability information set; sending the preset capability information set to the core network device. Alternatively, the access network device divides the source terminal capability information into terminal capability information sets according to capability attribute information, and sets terminal capability identifiers for the terminal capability sets; correspondingly stores the capability attribute information, terminal capability information, and terminal capability identifiers as preset The capability information set; finally, the preset capability information set is sent to the core network device.

It can be understood that since the transmission of the terminal capability information corresponds to the terminal capability attribute information, and the transmission of the terminal capability information is performed according to the terminal capability attribute information, then the terminal capability information is transmitted between network elements (that is, between communication devices). When transmitting, the terminal capability information corresponding to the terminal capability attribute information can be transmitted. In this way, since only the required terminal capability information corresponding to a certain terminal capability attribute information is sent, even if all the terminal capability information There are many, but what is required for a certain terminal capability attribute information is fixed. When implementing a service, transmitting the terminal capability information corresponding to a certain terminal capability attribute information corresponding to the service implementation will not increase the required time between communication devices. The pressure of terminal capability information transmission, on the contrary, reduces the huge signaling overhead caused by the transmission of capability information between communication devices.

Further, based on the above implementation, when the access network device performs handover, the transmission process of the terminal capability information is also involved. Using the above-mentioned access network device as the source access network device, the data transmission when the scene is switched is described.

S203. During the handover process to the target access network, acquire target terminal capability attribute information of the target access network.

S204. Acquire final terminal capability information corresponding to the target terminal capability attribute information from the core network device according to the target terminal capability attribute information.

S205. Send the target terminal capability attribute information and the final terminal capability information to the target access network device.

In the embodiment of this application, during the handover process of the source access network device to the target access network, the source access network device needs to send the terminal capability attribute information and corresponding capability information required by the target access network to the target access network. network equipment. Therefore, the source access network device can obtain the target terminal capability attribute information of the target access network; send the target terminal capability attribute information to the core network device, and the core network device obtains the target terminal capability attribute information corresponding to the target terminal capability attribute information from the preset capability information set. The final terminal capability information, and then the target terminal capability attribute information and the final terminal capability information are sent to the target access network device through the access network device.

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

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

Specifically, the source access network device acquires configuration information of the target access network; and acquires target terminal capability attribute information of the target access network according to the configuration information of the target access network. Alternatively, the source access network device receives the target capability information request sent by the target access network device, where the target capability information request carries target terminal capability attribute information.

It can be understood that since the core network equipment 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 equipment is divided based on the terminal capability attribute information, then, in the source access Network equipment and target access network equipment, and source access network equipment and core network equipment can transmit terminal capability information corresponding to terminal capability attribute information when transmitting terminal capability information. If the required terminal capability information is required, even if there are a lot of terminal capability information in total, it will not increase the pressure on the transmission of the required terminal capability information between communication devices, but it will also reduce the transmission of capability information between communication devices. There is a huge signaling overhead.

In some embodiments of the present application, data related to terminal capability information needs to be transmitted between access network equipment, core network equipment, and terminals. , and the inter-network element interface messages are limited by the carrying capacity, so the factor of the maximum carrying capacity of the inter-network element interface messages also needs to be considered during the data transmission process.

In the following, the transmission of terminal capability information-related data between any two network elements among the access network device, the core network device and the terminal is simplified as the data transmission between the sending end and the receiving end. Wherein, the corresponding relationship between the sending end and the receiving end is shown in Table 5.

table 5

sender Receiving end Core network equipment Access network equipment Access network equipment Core network equipment terminal Access network equipment source access network equipment target access network equipment

It should be noted that, in this embodiment of the application, the terminal capability information-related data sent by the core network device to the access network device is the target terminal capability information; the terminal capability information-related data sent by the access network device to the core network device is the source Terminal capability information; terminal capability information-related data sent by the terminal to the access network device is source terminal capability information; terminal capability information-related data sent by the source access network device to the target access network device is final terminal capability information. The specific process is as follows:

The sender determines whether the data related to the terminal capability information meets the preset network element interface message acceptance conditions; if the preset network element interface message acceptance conditions are not met, the sender processes the terminal capability information related data according to meeting the preset network element interface message acceptance conditions. Splitting to obtain N sub-terminal capability information-related data; wherein, N is an integer greater than or equal to 1; sending the N sub-terminal capability information-related data to the receiving end respectively.

In this embodiment of the present application, if the size of the data related to the terminal capability information exceeds the maximum carrying capacity of the inter-network element interface message, the sender may divide the data related to the terminal capability information into multiple messages for transmission.

Wherein, the preset network element interface message bearing condition is the network element interface message bearing capacity.

Exemplarily, if the maximum carrying capacity of the inter-network element interface message between the sending end and the receiving end is Xbit, and the data related to terminal capability information is Ybit, then the sending end can be divided into Y/X+1 message sending sub-terminal capabilities Information related data.

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

It is understandable that the sending end considers the bearing capacity of the interface between network elements when transmitting terminal capability-related data, which ensures the success rate of sub-terminal capability information-related data transmission, thereby improving the reception of terminal capability-related data at the receiving end. The data success rate also reduces the transmission pressure between network elements.

In the embodiment of the present application, the sender uses it when the message sender needs to tell the message receiver about message segmentation information to facilitate the integration of segmented messages.

In some embodiments of the present application, the sending end marks the N sub-terminal capability information-related data in segments to obtain the tag information of each sub-terminal capability information-related data, and the tag information is used to represent the sub-terminal capability information-related data. The segment position and the total number of segments; the sending end sends the data related to the capability information of each sub-terminal and the tag information of the data related to the capability information of each sub-terminal to the receiving end respectively.

In the embodiment of the present application, the receiving end can judge whether the data transmission is completed according to the tag information of each sub-terminal capability information-related data, and when the transmission ends, arrange the N sub-terminal capability information-related data according to the segmentation position in the above-mentioned tag information , and integrate back a terminal capability information-related data.

It should be noted that the sub-terminal capability information-related segment location where the sub-terminal capability information-related data resides may be the relevant information of which segment it belongs to, and may also include an identifier that it is the last segment, so as to judge whether the data transmission is over . Wherein, the data related to the capability information of the sub-terminal may be carried in the segmented message for transmission.

Based on segmentation considerations, after receiving multiple sub-terminal capability information-related data, the receiving end needs to integrate the multiple sub-terminal capability information-related data, then it needs to integrate the data according to the segment position, but the receiving end receives terminal capability related data. When sending messages, sometimes there may be situations where data sent by different objects is received. In this case, the sender needs to associate the data sent by itself with tags to indicate that these data are sent by the same object and need to be integrated into one data. Do it again.

In some embodiments of the present application, the sending end associates N sub-terminal capability information-related data to obtain an association mark of each sub-terminal capability information-related data, and the correlation mark is used to indicate that the sub-terminal capability information-related data belong to the same terminal capability For information-related data: the sending end sends the data related to the capability information of each sub-terminal and the associated mark of the data related to the capability information of each sub-terminal to the receiving end respectively.

In the embodiment of the present application, the receiving end can judge whether the data is transmitted by the same sending end according to the association mark, and integrate the N sub-terminal capability information related data transmitted by the same sending end.

That is to say, the sending end carries the segment number of the message and the segment number of the current message in the segmented message; the receiving end can associate the segmented data of the same message through the association identifier. The sender carries in the segmented message whether the current message has a subsequent segmented message, or carries a flag indicating whether it is the last segmented message.

Exemplarily, the segmented message, tag information and association identifier may be as shown in Table 6. In Table 6, segment message 1 carries segment data 1, and the segment position is the first segment. Segment message 1 carries segment data 2, and the segment position is the second segment; segment message 3 carries segment data 3, and the segment position is the third segment, and the association identifier of the segment data is 1, The representation is that the same data is divided into 3 segments, and the total number of segments is 3.

Table 6

segmented message Tag information Association ID Fragmented message 1 Segment Total 3, Segment 1 1 Fragmented message 2 Segment Total 3, Segment 2 1 Fragmented message 3 Segment Total 3, Segment 3 1

It can be understood that when transmitting data related to capability information of N sub-terminals, the sending end and receiving end take into account the timing and classification of data transmission, avoiding the problem of data integration errors and improving the accuracy of data transmission.
