When the terminal initiates a connection establishment request, the access network device requests the capability information of the terminal from the core network device, and then provides configuration for the terminal according to the capability information of the terminal.

The embodiments of the present application are proposed for the process of transmitting terminal capability information between 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 applied to a core network device. 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 the present application, based on the architecture shown in FIG. 1, in the process of communication between a terminal, an access network device, and a core network device, the implementation of many services or communication services requires terminal capability information. The embodiment of the present application provides a process for transmitting terminal capability information.

In the core network device, all the 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, 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, 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. 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 a 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 list the terminal capability attribute information listed above, but is not limited in the embodiment of the present application.

Passive acquisition: The core network device receives a 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 equipment needs terminal capability information when it performs resource configuration and control for the terminal. Therefore, the access network equipment can use the terminal capability attribute information that is specifically required in the process of service processing. The access network equipment does not necessarily need the same terminal capability attribute information each time. When the terminal network capability information required by the access network equipment does not exist on its own, it requests to obtain the core network equipment, that is, the access network equipment sends a terminal capability request. Message, the terminal capability request message carries terminal capability attribute information.

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

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

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

It should be noted that since the core network device can obtain the configuration information of the access network device with which it communicates when the network is deployed, the core network device can learn based on the configuration information of an access network device. The terminal capability attribute information required by the access network device.

It can be understood that, because the core network equipment transmits 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. (That is, between communication devices) when transmitting terminal capability information, 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 transmitted, even if all the terminal capability information is transmitted, It will not increase the pressure of required terminal capability information transmission between communication devices, but will also reduce the transmission of capability information between communication devices, which will cause huge signaling overhead.

Further, in the data transmission method provided in 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. Obtain 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 the terminals in a 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 collectively 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 centrally stores a terminal capability information set that divides source terminal capability information according to capability attribute information, and a terminal capability identifier corresponding to the terminal capability information set.

Here, the source terminal capability information is all the terminal capability information of the terminal server that is accessed by the access network device corresponding to the core network device. 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 the embodiment of the present application.

It should be noted that, in the embodiment of the present application, the preset capability information set adopts two storage methods, one can directly form a correspondence relationship between capability attribute information and capability information, and one can be the capability information set and Correspondence between capability identification and capability attribute information.

For example, the storage of specific capability attribute information and terminal capability information can be shown in Table 1 below. The capability attribute information is stored as: PLMN1, frequency band 1, frequency band 1 + frequency band 2 (band combination information), and NB-IoT Terminal capability information corresponding to the terminal (terminal type information).

Table 1

NB-IoT终端NB-IoT terminal	终端在NB-IoT上的能力信息Capability information of the terminal on NB-IoT

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

Exemplarily, the capability attribute information based on Table 1: PLMN1, frequency band 1, frequency band 1 + frequency band 2 (frequency band combination information), and NB-IoT terminal (terminal type information), and the corresponding terminal capability information is expressed in the form: : Display the capability information of the terminal in band 1 or the capability information of band 1 is stored as a container; Display the capability information of the terminal in band 1 or the capability information of band 1 is stored as a container ; Display the capability information of the terminal in band 1 + band 2 or store the capability information in band 1 + band 2 as a container; save the displayed capability information of the terminal on NB-IoT, Or the capability information on NB-IoT is stored as a container. The embodiments of the present application are 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 acquiring the terminal capability attribute information of the access network device, the core network device can store the terminal capability information set divided according to the capability attribute information and the terminal capability information set corresponding to the preset capability information set. Terminal capability identification, so the core network device can obtain the target terminal capability set corresponding to the terminal capability attribute information and the target terminal capability identification corresponding to the target terminal capability set from the preset capability information set, and then the target terminal capability set and the target The terminal capability identification is sent to the access network device.

It should be noted that for the correspondence between the capability information set (referring to the terminal capability information set), the capability identifier (referring to the terminal capability identifier), and the capability attribute information, the capability information supported by the terminal is stored in the capability information set. For specific capability attribute information, an index (that is, capability identification) is adopted. When the access network device needs the capability information corresponding to the specific capability attribute, the core network device may send the capability set corresponding to the capability attribute and the corresponding index identifier to the access network device.

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

It should be noted that, in the embodiment of the present application, the terminal capability information set includes multiple terminal capability information, so the access network device needs to find the required capability information from this much information, which can be implemented by using the capability identifier as an index. .

Exemplarily, when the capability identifier adopts a continuous integer as a mark, as shown in Table 2, PLMN-1 to PLMNN correspond to the capability identifier 1-N capability identifier N. Each terminal capability information in the terminal capability identification and terminal capability information set may be one-to-one. Each frequency band corresponds to a capability identifier. As shown in Table 3, the frequency band combination: frequency band 1 + frequency band 2 up to frequency band N-1 + frequency band N corresponds 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, band 1-band N corresponds to the capability identifier 1-M, and M is smaller than N. The capability identifier N terminal capability identifier and each terminal capability information in the terminal capability information set may be many-to-many, and different frequency bands correspond to different capability identifiers, but at least two terminal capability information have the same capability identifier.

It should be noted that, in the embodiments of the present application, the representation principles of the capability identifiers corresponding to all the terminal capability information sets are the same, that is, the presentation forms of the capability identifiers are the same. For example, 1-N Arabic numerals are used as the capability identifier. , There are cases where different capability information sets use the same capability identifier.

It can be understood that, because the core network equipment 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 equipment is divided based on the terminal capability attribute information, then, in When transmitting the terminal capability information set between network elements (that is, between communication devices), 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, then even There is a lot of total terminal capability information, and it will not increase the pressure of the required terminal capability information set transmission between communication devices. The required terminal capability information set is fixed, but it also reduces the capability information set in the communication device. Transmission between them will bring huge signaling overhead.

Example 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 the terminal capability attribute information sent by the core network device.

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

In the embodiment of the present application, when the access network performs resource configuration and control for the terminal, it needs the terminal capability information corresponding to the terminal to implement, and all the terminal capability information is stored in the core network device. When conducting business, target terminal capability information corresponding to terminal capability attribute information can be received from the core network device, so that the access network device can provide configuration information to the target terminal according to the target terminal capability information to implement the service. The terminal capability information is stored in the core network device in such a manner that the terminal capability attribute information corresponds to the terminal capability information.

Capability information of the PLMN to which the terminal belongs;

Capability information of the terminal on a preset frequency band;

Terminal type information.

It should be noted that, in the 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 to the core network device when required, or may be obtained by the core network device according to According to the configuration information of the access network device, the target terminal capability information corresponding to the terminal capability attribute information is proactively obtained according to the configuration information and sent directly to the access network device.

In other words, for the 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 the terminal capability attribute information, so the core network device according to the terminal Capability attribute information, the target terminal capability information is found from the preset capability information set, and sent to the access network device.

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

For example, the access network device may carry a terminal capability request message in the initial UE message of the N2 interface, or 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 (ie, source terminal capability information) of all the terminals in a 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 source terminal capability information may be stored in the core network device in advance, 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: at the beginning of access to the network, for example, the access network device receives the source terminal capability information when the terminal registers; then, the source terminal capability information is sent to the core network device for the core. 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 after the access network device divides source terminal capability information of different terminals according to the terminal capability attribute information, and then sends it to the core network device for storage. The specific implementation is that 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 as pre-stored correspondences. Set the capability information set; and send 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 the capability attribute information, and sets a terminal capability identifier for the terminal capability set; and stores the capability attribute information, the terminal capability information, and the terminal capability identifier as presets. Capability information set; finally, the preset capability information set is sent to the core network device.

It can be understood that, because the transmission of terminal capability information corresponds to the terminal capability attribute information, the terminal capability information is transmitted according to the terminal capability attribute information. Then, the terminal capability information is performed between network elements (that is, between communication devices). During transmission, 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 is total Many, but what is required for a certain terminal capability attribute information is fixed. When the 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 required communication between the communication devices. The pressure of terminal capability information transmission has also reduced the transmission of capability information between communication devices, which will cause huge signaling overhead.

Further, based on the above implementation, when the access network device performs a handover, a transmission process of terminal capability information is also involved. The above-mentioned implementation of the access network device is used as the source access network device to explain data transmission when switching scenarios.

S203: During the handover to the target access network, obtain 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 the present 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 equipment. Then, 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 from the preset capability information set corresponding to the target terminal capability attribute information The final terminal capability information, and then send the target terminal capability attribute information and final terminal capability information to the target access network device through the access network device.

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

In some embodiments of the present application, the target terminal capability attribute information of the target access network obtained by the source access network device may be obtained according to the configuration information of the target access network, or may be obtained by requesting the target access network device. . That is, the source access network device can 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 the target access network; and according to the configuration information of the target access network, obtains target terminal capability attribute information of the target access network. Alternatively, the source access network device receives a target capability information request sent by the target access network device, and the target capability information request carries target terminal capability attribute information.

It can be understood that, because the core network equipment transmits 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, the source access Network equipment and target access network equipment, as well as source access network equipment and core network equipment, when transmitting terminal capability information, they can transmit terminal capability information corresponding to the terminal capability attribute information. Required terminal capability information, then even if all the terminal capability information is large, it will not increase the pressure of required terminal capability information transmission between communication devices, but will also reduce the transmission of capability information between communication devices. Comes with huge signaling overhead.

Example three

Based on the implementation of Embodiment 1 and Embodiment 2, for example, an embodiment of the present application provides a data transmission method, as shown in FIG. 5, including:

S301. At least one terminal sends source terminal capability information to an access network device during registration.

S302. The access network device sends source terminal capability information to the core network device.

Among them, the data related to the capability information of the sub-terminal may be carried in a segmented message for transmission.

Based on the consideration of segmentation, after receiving the multiple sub-terminal capability information related data, the receiving end needs to integrate the multiple sub-terminal capability information related data, then the data needs to be integrated according to the segmented position, but the receiving end's receiving terminal capability is related In the case of information, there may be cases where data sent by different objects is received. In this case, the sender also needs to mark the data sent by the sender to indicate that these data are sent by the same object and need to be integrated into one data. Process it again.

In some embodiments of the present application, the transmitting end associates N sub-terminal capability information related data to obtain an association tag of each sub-terminal capability information related data. The association tag is used to indicate that the sub-terminal capability information related data belongs to the same terminal capability. Information-related data; the sender sends the data associated with each child terminal's capability information and the associated flags of each child terminal's capability information to the receiver.

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.

In other words, the sender carries the number of message segments and the current message segment in the segmented message; the receiver can associate the segmented data of the same message through the association identifier. The sending end carries in the segmented message whether there is a subsequent segmented message of the current message or 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, the 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, the segment position is the third segment, and the associated identifier of the segment data is 1. Characterization is that the same data is divided into 3 segments, and the total number of segments is 3.
