Description

TECHNICAL FIELD

[0001] The present disclosure relates to the field of communication, and in particular, to a capability interaction method and apparatus, and a storage medium. BACKGROUND

[0002] With the development of wireless communication technology, there are more and more multi-card terminals in the market. At present, the processing mode for multi-card terminals is mainly based on the implementation of each terminal manufacturer, which leads to many different terminal behaviors and processing modes. For example, dual-card single standby, dual-card dual standby single access, dual-card dual standby dual access, etc., and can cause some problems. For example, when the multi-card terminal communicates with a first system, it needs to switch the connection to a second system for operation from time to time, such as listening to paging, performing measurement, reading system message, etc. This can affect the performance of the first system. If these operations are not performed in the second system, such as not listening to paging, it can cause the service of the second system to be unable to be established. For some operations, the multi-card terminal needs to release the RRC (Radio Resource Control) connection with the first system, such as long-time-consuming operations, and for some operations, the multi-card terminal does not need to release the RRC connection with the first system, such as short-time-consuming operations.

[0003] The multi-card terminal needs to know the paging cause of the second system in order to better decide whether to leave the first system and whether to release the RRC connection with the first system. This requires the base station to inform the paging cause, but the paging cause capability interaction is not supported between base stations at present. SUMMARY

If the first base station determines, through previous interaction with the second base station regarding the paging reason capabilities they each support, that at least one of the second base station does not support paging reason capabilities, and determines that the second base station needs to transmit the first paging reason, the first base station can determine that it will not receive the first paging reason sent by the second base station through the inter-base station interface.

[0165] In the above embodiments, if the first base station determines that at least one of itself and the second base station does not support paging reason capability, and determines that the second base station needs to transmit the first paging reason, it can determine that it will not receive the first paging reason sent by the second base station through the inter-base station interface. This improves the availability of the paging reason mechanism.

The purpose of interacting the paging cause based on the paging cause capability supported by different base stations is achieved, and the availability is high.

[0178] In the above embodiment, the first base station and the second base station interact the paging cause capability supported by each other, so that in the case that at least one does not support the paging cause capability, it is determined that the second paging cause will not be sent to the second base station through the inter-base station interface.

[0186] The second paging cause is sent by the second base station when the second base station determines that both the second base station and the first base station support the paging cause capability and determines to transmit the second paging cause.
