摘要： Seamless client roaming for Multi-Link Device (MLD) clients may be provided. First, a Traffic Identifier (TID)-to-link map may be established by an Upper Service Access Point (U-SAP) of a multi-AP MLD entity that assigns subsets of TIDs to at least two links of the entity. For example, a client device logically associates with the U-SAP, while the client device physically connects to a first and second AP of the entity on a respective first and second link, where the first and second AP include first and second Lower Service Access Points (L-SAPs) and are non-collocated. Next, using the map, data received at the U-SAP is directed over one of the two links for transmission to the client device. Further, frame aggregation and block acknowledgment functions may be performed by one of the first or second L-SAP based on whether data transmission is over the first or second link.

摘要： A method for Xx/Xn interface communication is disclosed, comprising: at an Xx/Xn gateway for communicating with, and coupled to, a first and a second radio access network (RAN), receiving messages from the first RAN according to a first Xx/Xn protocol and mapping the received messages to a second Xx/Xn protocol for transmission to the second RAN; maintaining state of one of the first RAN or the second RAN at the Xx/Xn gateway; executing executable code received at an interpreter at the Xx/Xn gateway as part of the received messages; altering the maintained state based on the executed executable code; and receiving and decoding an initial Xx/Xn message from the first RAN; identifying specific strings in the initial Xx/Xn message; matching the identified specific strings in a database of stored scripts; and performing a transformation on the initial Xx/Xn message, the transformation being retrieved from the database for stored scripts, the stored scripts being transformations.

摘要： An embodiment of the present disclosure may provide an inter-MeNB handover method in a small cell system, including: making, by a source MeNB and/or target MeNB, a determination as to whether to maintain a SeNB when handover is performed; and triggering different handover processes according to a result of the determination as to whether to maintain the SeNB. Another embodiment of the present disclosure may further provide an inter-MeNB handover device in a small cell system. With the inter-MeNB handover method and device in a small cell system provided by the present disclosure, unnecessary deletion and re-establishment of the bearers at the SeNB for the UE may be reduced. False bearer deletion may be avoided and data forwarding may be reduced. Furthermore, the SeNB may be maintained according to network deployment and SGW re-selection may be supported. Therefore, system capacity and transmission speed of the data may be improved.

摘要： A wireless station (STA) operating as a non-simultaneous transmit-receive (NSTR) soft access point (AP) multi-link device (MLD) associated with a primary link and a non-primary link determines that the non-primary link is unavailable, and transmits, on only the primary link, a frame carrying an indication of the unavailability of the non-primary link. The NSTR softAP MLD may set a Do Not Transmit (DNT) bit to a value of 1 and may operate as a single-link device on the primary link based on the unavailability of the non-primary link. In some instances, the NSTR softAP MLD determines that the non-primary link is available while operating as the single-link device on the primary link, resets the DNT bit based on the availability of the non-primary link, and transmits the reset DNT bit in another frame on only the primary link.

摘要： The present application discloses a method and eNB equipment for supporting seamless handover. The method comprises the following steps of: receiving, by a target eNB, random access information or an RRC connection reconfiguration completion message from a UE; transmitting, by the target eNB, a data transmission stopping indication message to a source eNB; and, stopping, by the source eNB, transmitting downlink data to the UE, and/or stopping, by the source eNB, receiving uplink data from the UE. The present invention further provides several other methods and eNB equipments for supporting seamless handover. By the methods for supporting seamless handover provided by the present invention, the delay of data transmission and the unnecessary data transmission or unnecessary data monitoring of a source eNB can be avoided, the waste of resources and the power consumption can be reduced, and the missing and duplication transmission of data can be avoided.

摘要： A User Equipment (UE) including a wireless transceiver and a controller is provided. The wireless transceiver performs wireless transmission and reception to and from a first cellular station and a second cellular station. The controller continues to send or receive UP data to or from the first cellular station via the wireless transceiver after receiving a handover command message for a handover of the UE from the first cellular station to the second cellular station, and receives a Radio Resource Control (RRC) request message from the second cellular station via the wireless transceiver after sending a handover complete message to the second cellular station. Also, the controller detaches from the first cellular station in response to receiving the RRC request message.

摘要： An apparatus includes a includes a communication interface and a processor operably coupled to the communication interface. The communication interface receives signaling that indicates edge application service relocation for transferring a user equipment (UE) session for a UE to a target edge data network. The processor identifies an edge application service in the source edge data network processing media content corresponding to the UE session; generates a resource template for the edge application service including requirements for running the edge application service; transmits a request for the edge application service relocation to the target edge data network, the request including the resource template; and enables the edge application service relocation for the user equipment from the edge application service at the source edge data network to an edge application service at the target edge data network.
