  • Publication number: 20250047573
    Abstract: Embodiments include methods for a user equipment (UE) configured to perform quality-of-experience (QoE) measurements in a radio access network (RAN). Such methods include performing QoE measurements for one or more applications operating on a UE application layer and detecting occurrence of at least one event or condition that triggers a RAN-visible QoE(RVQoE) report. Such methods include, based on detecting the occurrence of the at least one event or condition, sending to a RAN node at least one RVQoE report that includes the following: one or more RVQoE metrics or RVQoE values, each based on the QoE measurements performed; and one or more trigger-related indications associated with the detected event or condition. Other embodiments include complementary methods for a RAN node as well as UEs and RAN nodes configured to perform such methods. FIG. 8 is selected for publication.

  • Publication number: 20240357401
    Abstract: Embodiments include methods for a user equipment (UE) configured for application-layer measurements in a radio access network (RAN). Such methods include receiving one or more configurations of application-layer measurements to be performed by the UE while the UE is connected to the RAN and, in response to an interruption in the UE's connection to the RAN while the CE is configured to perform the application-layer measurements, sending to the RAN a request to resume the UE's connection or a request to reestablish the UE's connection. Such methods also include, in response to the request sent to the RAN, receiving from the RAN a command to setup a new connection to the RAN and in response to the command, releasing the received configurations and discarding any stored application-layer measurement reports. Other embodiments include complementary methods for RAN nodes, as well as UEs and RAN nodes configured to perform such methods.

  • Patent number: 12082061
    Abstract: According to an aspect, a source node determines (1002) that a UE served by the source node is a candidate for conditional handover configuration. The source node sends (1004), to a target node for conditional handover of the UE, a conditional handover request that includes one or more parameters indicative of a likelihood that handover of the UE to the target node will be executed. The target node receives (1102) the request and parameters and allocates (1104) resources for the UE, taking into account the likelihood that handover of the first UE to the target node will be executed. The target node sends (1106) handover configuration information for the first UE to the source node, in response to the conditional handover request.

  • Patent number: 11968571
    Abstract: A method performed by a target node (111) in a communications network (100). The method is for handling reconfigurations of a User Equipment (UE) (120) during a conditional handover. The target node (111) has received a conditional handover request for the UE (120) from a source node (110) and has sent a handover request acknowledgement to the source node (110) based on a current configuration of the UE (120). The target node (111) performs (401) synchronization and random access with the UE (120) based on the UE configuration used for the handover request acknowledgement. The target node (111) obtains (403), after performing (401) the synchronization, information regarding an updated configuration of the UE (120). The updated configuration has taken place since the handover request acknowledgement was sent to the source node (110).
