Background
The inter-system Dual connectivity technology refers to that a terminal is simultaneously connected to two systems of different communication systems for communication, for example, the terminal is simultaneously connected to LTE (Long Term Evolution) and 5G New Radio (NR, New Radio), that is, Dual connectivity (DC, Dual connectivity) between LTE and NR.
While the terminal performs dual connection of different systems, a carrier aggregation technology may also be used in each system, for example, when the terminal performs dual connection of LTE and 5G NR, three-carrier aggregation is performed in LTE, and two-carrier aggregation is performed in NR.
When the dual connection technology of the different system terminal is used in combination with the carrier aggregation technology, the baseband processing capability and the radio frequency capability of the terminal are shared, so that the corresponding capability negotiation of the terminal is required between different systems. For example, one terminal may support LTE aggregation of 3 carriers while making dual connectivity with NRs aggregated by 2 carriers; the LTE aggregation of 2 carriers and the NR of 3 carriers can be supported to carry out double connection; LTE with 1 carrier may also be supported with dual connectivity with NR aggregated with 4 carriers.
Because too many frequency bands and frequency band combinations are supported by the terminal, frequency band and frequency band combination support information reported to the network by the terminal under a scene of dual-connection of different systems is too large, and uplink overhead and burden are heavy.

In order to make the technical problems, technical solutions and advantages of the present invention more apparent, the following detailed description is given with reference to the accompanying drawings and specific embodiments.
Referring to fig. 1, fig. 1 is a schematic flowchart of an information interaction method according to an embodiment of the present invention. As shown in fig. 1, an information interaction method is used for a first base station supporting dual connectivity of different systems and a first communication system, and the method includes the following steps:
The embodiment of the invention is applied to two base stations (namely a first base station and a second base station) supporting two different communication modes of dual connection of different systems, for example, the first communication mode can be one of an LTE system and an NR system, and the second communication mode is the other one of the LTE system and the NR system. That is, when the first communication system is an LTE system, the second communication system is an NR system; when the first communication system is an NR system, the second communication system is an LTE system.
In the embodiment of the present invention, the first base station may interact with the second base station, for example, the first base station may send frequency band information to the second base station, and the second base station may also send frequency band information to the first base station. The first base station (or the second base station) may also interact with the mobile communication terminal, for example, the first base station may transmit the frequency band information received from the second base station to the mobile communication terminal, and the mobile communication terminal may also transmit the frequency band support information corresponding to the frequency band information to the first base station. The following specifically describes each of step 101 to step 103.
In this step, the first base station interacts with the second base station, and the second base station may notify the frequency band information supported or interested by the second base station to the first base station paired with the second base station for dual connectivity. Specifically, the second base station sends the frequency band information to the first base station, and the first base station receives the frequency band information sent by the second base station.
The frequency band information supported by the base station can be understood as frequency band information in which the base station can normally work; the frequency band information of interest to a base station may be understood as frequency band information that is not supported by the base station but is supported by neighboring base stations of the base station.
The frequency band information should also include frequency band combination information, and here, the frequency band combination information may be understood as frequency band combination information of carrier aggregation.
And 102, transmitting the frequency band information to the mobile communication terminal.
In this step, the first base station interacts with the mobile communication terminal, and the first base station may notify the mobile communication terminal of the frequency band information supported by or interested in the second base station paired with the first base station for dual connectivity.

Specifically, the first base station transmits at least a part of the frequency band information to the mobile communication terminal, and the mobile communication terminal may receive at least a part of the frequency band information transmitted by the first base station.
In addition, the first base station may directly transmit all of the frequency band information transmitted by the second base station to the mobile communication terminal, or may transmit all or part of the frequency band information to the mobile communication terminal after screening the frequency band information transmitted by the second base station. The embodiments of the present invention are not limited to these examples.
As a preferred embodiment, the first base station sends the mobile communication terminal after screening the frequency band information, for example, the frequency band information sent by the second base station to the first base station is f1 and f2, if the first base station only supports dual connectivity with f1, the first base station may delete the information related to f2, so that the mobile communication terminal only receives the frequency band information f 1.
The preferred embodiment can further reduce the overhead reported by the mobile communication terminal.
And 103, receiving the frequency band support information sent by the mobile communication terminal.
In this step, the mobile communication terminal interacts with the first base station, and the mobile communication terminal may report information about a frequency band or a frequency band combination (i.e., frequency band support information) supported by the mobile communication terminal operating in the second communication system to the first base station.
The frequency band support information reported by the mobile communication terminal can be correspondingly adjusted and reported according to the received frequency band or frequency band combination information which is sent by the first base station to the first base station and is supported or interested by the second base station.
Specifically, the first base station receives frequency band support information corresponding to at least a part of the frequency band information transmitted by the mobile communication terminal.
As a specific embodiment, the frequency band information may be transmitted through an interface between the first base station and the second base station, such as an Xn interface; the frequency band information can also be sent to the core network through the second base station, and the core network is sent to the first base station.

And a second condition: when the first base station determines to add the carrier of the second base station for dual connectivity, the first base station sends a request message for requesting the frequency band information to the second base station, and the second base station triggers to send the frequency band information to the first base station.

The first condition is as follows: and when the second base station establishes the adjacent area relation with the first base station, the first base station receives the frequency band information sent by the second base station.
And a second condition: and when the second base station determines to cooperate with the first base station to provide the dual connectivity service, the second base station sends the frequency band information to the first base station.
