In the NSA architecture, the UE (User Equipment, user equipment) can be connected to the base station of the first radio access network and the base station of the second radio access network at the same time, the base station of the first radio access network can be, for example, an eNB (evolved base station), the second radio access network The base station of the network may be, for example, a gNB (5G base station), thereby enabling the UE to obtain the service of the first radio access network and the service of the second radio access network at the same time.

In the application process, when the UE that supports NSA is powered on, it will search for a cell to camp on. The UE can learn whether the network supports dual connectivity through the upperLayerIndication-r15 (upper layer indication-r15) of SIB2 in the SIB (System Information Block) message. Dual connectivity includes the connection between the UE and the first radio access network and the connection between the UE and the second radio access network. The connection of the radio access network, such as the connection of the UE to the 4G radio access network and the connection of the UE to the 5G NR (New Radio). If the network does not support dual connectivity, the UE may first camp on a non-dual connectivity cell to obtain the service of the first radio access network, and then camp on a cell that supports dual connectivity through cell reselection to obtain the second wireless access network. Internet access services.

Based on this, the inventors of the present invention found that, when the UE performs reselection, since the neighbor cell information received by the UE usually only includes information such as the frequency, reselection threshold, and reselection priority of the neighboring cells, but does not include the neighbor cell information. Indication information of whether the frequency points of the cell and/or neighboring cells support dual connectivity. If the reselected neighboring cell also does not support dual connectivity, the UE needs to perform cell reselection again, so that the UE cannot obtain the service of the second radio access network in time.

Wherein, the dual connection indication information EN-DCSupported of frequency point information 3 indicates FALSE, indicating that inter-frequency carrier frequency point 3 does not support dual connection, and cellReselectionPriority indicates that the priority of frequency point 3 is 5.

S320: According to the indication information in the dual connectivity indication information for indicating whether the inter-frequency carrier frequency supports dual connectivity, among multiple inter-frequency carrier frequencies with the same priority, determine an inter-frequency carrier that supports dual connectivity Frequency.

For example, in frequency points 1 and 3 having the same priority, determine an inter-frequency carrier frequency point that supports dual connectivity, such as the above inter-frequency carrier frequency point 1.

S330: Camp on a neighboring cell in the one inter-frequency carrier frequency point supporting dual connectivity.

The UE measures the one inter-frequency carrier frequency point 1 that supports dual connectivity, and if the inter-frequency carrier frequency point 1 satisfies the reselection condition, it resides in a neighboring cell in the inter-frequency carrier frequency point 1.

Therefore, a method for cell reselection provided by an embodiment of the present application, according to the indication information used to indicate whether the inter-frequency carrier frequency point supports dual connectivity in the dual connectivity indication information, among multiple cells with the same priority In the inter-frequency carrier frequency points, determine an inter-frequency carrier frequency point that supports dual connectivity; reside in a neighboring cell in the inter-frequency carrier frequency point that supports dual connectivity, so that the UE can know the inter-frequency carrier frequency point in time Whether to support dual connectivity, so that the UE can select the inter-frequency carrier frequency that supports dual connectivity among the inter-frequency carrier frequencies with the same priority, so that the UE can quickly obtain the second radio access under the non-standalone network architecture. network services.
