In a communication system according to the present invention, a UE and an MeNB perform both a direct communication and a communication through a SeNB. Along with moving of the UE, a handover process of switching the MeNB to which the UE is connected, from an S-MeNB to a T-MeNB is performed. The connection between the UE and the SeNB is maintained during the handover process. The UE starts transmitting data to the SeNB before a communication path between the UE and the MeNB is changed from a path formed by the S-MeNB and the UE to a path formed by the T-MeNB and the UE.

A system for delaying or inhibiting data is provided in order to shorten the time required for a reselection process from a first communication protocol to a second communication protocol. Reselection from the first communication protocol to the second communication protocol (e.g., 3G to 4G) requires a period of time without data transfers to allow the reselection to complete. The system delays or inhibits data transfers on the mobile device until the reselection process completes or the mobile device is idle for a predetermined length of time. In an embodiment, the system can buffer outgoing data and then send the data once the reselection has completed. In other embodiments, the system can drop packet sessions or ignore incoming packet pages. In another embodiment, the system can delay or inhibit data based on the priority of the data.

A method is performed in a first infrastructure equipment for a handover of a wireless device from the first infrastructure equipment as a source to a second infrastructure equipment as a target. The method comprises maintaining a mapping between a plurality of packet bearers and a data radio bearer for the wireless device, each of the plurality of packet bearers being configured to provide a specified quality of service, determining that the wireless device should handover from the first infrastructure equipment to the second infrastructure equipment, determining that the second infrastructure equipment does not support the mapping of the plurality of packet bearers to the data radio bearer, and providing an indication of a mapping of the plurality of packet bearers for the second infrastructure equipment after handover to one of a core network equipment and the second infrastructure equipment.

A method and an apparatus for filtering a wireless signal by parsing a wireless signal transmitted from a surrounding wireless terminal so as to extract channel information of the surrounding wireless terminal in a MAC frame and performing adaptive filtering on the wireless signal.

Methods, systems, and apparatuses for device routing management are disclosed. A client device of a wireless network may roam from a first access point to a second access point of the wireless network. The second access point, or the client device itself, may send a network message indicating the client device is currently being served by the second access point. The message may cause a network mapping stored at the first access point and/or at each device associated with the wireless network to be updated to indicate the client device is associated with the second access point, thereby enabling proper routing of network traffic to the client device via the second access point.

Disclosed in the present application are a method and device for data forwarding The method includes: sending to a second wireless access network node a first interface message requesting to modify the node; receiving a second interface message returned by the second wireless access network node, where the information in the second interface message includes first radio resource control (RRC) configuration information and first data forwarding and distribution information used for indicating first data that needs data forwarding; and sending a third interface message carrying the information in the second interface message to a third wireless access network node, to request the third wireless access network node to receive the first data forwarded from the second wireless access network node.

A method and apparatus for an indication of serving cell communication quality to a target cell during mobility in a wireless communication system is provided. A wireless device, which keeps communicating with a source node while initiating a mobility from the source node to a target node, transmits, to the target node, information related to a communication quality of the source node.

Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may determine, via a first subscription of the UE, a trigger event for a conditional handover of the UE from a source network entity to a target network entity. The UE may determine, based at least in part on the trigger event, that a target band associated with the target network entity is not compatible with a serving band associated with a second subscription of the UE. The UE may store the trigger event for the conditional handover in a buffer of the UE. The UE may perform an action related to the conditional handover based at least in part on a condition being satisfied. Numerous other aspects are described.
