The present disclosure provides an information sending method, including in response to determining that a second SIM card in a connected state satisfies a handover condition for handing over the second SIM card from a first base station to a second base station, sending context information of a first SIM card to the first base station through the second SIM card, wherein the first SIM card is in an inactive state. According to the technical solutions of the present disclosure, the first SIM card does not need to send the context information to the second base station separately, nor temporarily adjust its state, thus the times of communication between the terminal and the base station are reduced, the communication progress is simplified and the communication resources are saved.

In one embodiment, a network assurance service that monitors a wireless network identifies a set of wireless network anomalies detected in the wireless network that are associated with a set of one or more network measurements. The network assurance service classifies the set of wireless anomalies as radio-related or backend-related. The network assurance service, when the set of wireless anomalies are classified as radio-related, determines that the wireless anomalies are recurring for a particular wireless access point in the network. The network assurance service initiates a change to the wireless network in part to move clients in the wireless network from the particular wireless access point to another wireless access point in the network.

A method for data forwarding in a small cell system comprises: sending by a master base station (MeNB) to a target secondary base station (SeNB) information of a source SeNB or a source SeNB cell where a user equipment (UE) is located; determining by the target SeNB whether a direct data forwarding is feasible; notifying, by the target SeNB, the MeNB whether the direct data forwarding is feasible; and determining by the MeNB whether it is a direct data forwarding or an indirect data forwarding. The method for data forwarding provided in the present application may support both the direct data forwarding and the indirect data forwarding based on actual situation of the network, reduce data loss and failure of data forwarding, and improve the efficiency of data forwarding.

A wireless roaming method and an apparatus, a storage medium and an access point device are disclosed. The wireless roaming method comprises: receiving, from an overlapping access point, first signal strength indication information that describes signal strength when a station transmits a data packet to the overlapping access point via a current channel, wherein the coverage of the overlapping access point overlaps with that of a current access point, the station accesses to the current access point, and the current access point operates on the current channel; measuring second signal strength information that describes signal strength when the station transmits a data packet to the current access point via the current channel; and sending the first signal strength indication information and the second signal strength indication information to the station, and/or generating a switching instruction based on the first signal strength indication information and the second signal strength indication information and sending at least the switching instruction to the station. The technical solution of the present disclosure can improve the efficiency of wireless roaming.

Novel techniques are described for generation, distribution, and management of route connectivity optimization (RCO) mapping. For example, as mobile devices traverse travel routes serviced by one or more mobile networks, they can experience periods of different levels of connectivity with the mobile network(s). Embodiments can collect route segment connectivity data as experienced by consumer devices during traversal through mobile networks (e.g., indicating, for each route segment, which carriers are providing service to a mobile device, the level of service being provided, etc.). A RCO can be computed and stored for the set of route segments as a function of the route segment connectivity data. The RCO can be requested by consumers, and a corresponding link can be generated. Selecting the link can provide the consumers with remote access to the RCO, with which the consumers can generate connectivity-optimized route guidance maps.

Various aspects of the present disclosure generally relate to wireless communication. In some aspects, an integrated access and backhaul (IAB) node may receive, from a first IAB donor centralized unit (CU) via a first parent distributed unit (DU), a first indication to establish a first connection with a second parent DU associated with a second IAB donor CU. The IAB node may establish the first connection with the second parent DU. The IAB node may establish a second connection with the first IAB donor CU via the second parent DU, the first connection and the second connection forming a target path between the IAB node and the first IAB donor CU. Numerous other aspects are provided.
