摘要： An orchestration and mediation (O/M) stack to be installed in a user device that subscribes to a carrier system is provided. The O/M stack configures the user device to receive a policy for accessing a plurality of different network slices that are logical networks virtualized on a physical infrastructure of the carrier system. The O/M stack configures the user device to coordinate each application's access to different services provided by the plurality of different network slices. An application is allowed access to a particular network slice when the application and the user device meet a condition specified by the received policy for accessing the particular network slice.

摘要： Systems, devices, and techniques described herein relate to selectively implementing an expedited retransmission time. In some examples, a call setup message is transmitted to a first network system associated with a first network access technology. A transfer request may be received from the first network system. The transfer request may indicate handover or redirection to a second network system associated with a second network access technology. Upon expiration of the expedited retransmission time after receiving the transfer request, the call setup message can be retransmitted to the second network system.

摘要： A wireless communication system may support two types of networks, such as a 4th-Generation (4G) network and a 5th-Generation (5G) network. The 4G network is accessed through Long-Term Evolution (LTE) base stations. The 5G network is accessed through New Radio (NR) base stations. LTE base stations are configured to broadcast information regarding 5G availability. For example, an LTE base station may indicate whether it is configured to support Non-Standalone Architecture (NSA) Dual Connectivity in conjunction with an associated NR base station. When a communication device receives an indication that NSA Dual Connectivity is available, the communication device scans and measures signal strengths on each of multiple frequencies that are potentially being used by the NR base station. This can be done without decoding of the signals. If a signal having a sufficient signal strength is found, the communication device displays a 5G symbol in its status bar.

摘要： A codec-specific radio link adaptation procedure can be implemented at the radio access network (RAN) level. A process includes receiving, from a mobile device, a bitstream carrying speech data as part of a communication session, determining, based at least in part on a result of inspecting packets of the bitstream or a notification message from an Internet Protocol (IP) Multimedia Subsystem (IMS) core, that the bitstream is associated with a codec that provides improved performance of the mobile device as compared to legacy codecs in similar radio conditions; and adapting a radio link for the communication session according to the codec.

摘要： Systems, devices, and techniques described herein relate to intelligently allocating network resources to Quality of Service (QoS)-sensitive data traffic. An example method includes identifying a request to deliver QoS-sensitive services to a User Equipment (UE) over at least one delivery network. The at least one delivery network may include at least one reserved resource and at least one pooled resource. The QoS-sensitive services are determined to be delivered over the at least one pooled resource. In addition, delivery of the QoS-sensitive services is caused over the at least one pooled resource.

摘要： A radio frequency front end (RFFE) is configured to support dual connectivity communications, in which two different radio access technologies such as 4th-Generation (4G) Long-Term Evolution (LTE) and 5th-Generation (5G) New Radio (NR) data connections are used simultaneously for communications between a wireless communication device and respective LTE and NR base stations. In described embodiments, the RFFE uses two power amplifiers to reduce intermodulation distortion (IMD). The two power amplifiers produce output signals for a 4G LTE uplink and a 5G NR uplink, respectively. The RFFE also has a combiner that mixes the output signals to produce a composite output signal representing both LTE and NR data. Bypass switches may be used to configure the RFFE so that it can be used for single conventional 4G LTE communications.

摘要： Systems and methods for providing improved cell-edge antenna performance are disclosed. The system can use various signal quality indicators (SQIs) for each user equipment (UE) on a particular wireless base station (WBS) or network. When one or more of these metrics reaches a first predetermined value for a particular UE, the WBS or the UE can decide to activate a diversity receive (Rx) antenna on the UE to improve reception. If one or more of these metrics continues to degrade to a second predetermined value, however, the WBS or the UE can deactivate the diversity Rx antenna and activate a primary Rx antenna. Deactivating the diversity antenna when signal quality/strength is poor can improve reception by reducing interference between the diversity Rx antennas. Disabling the diversity Rx antenna when signal quality/strength is poor can also decrease the number of retransmission requests from each UE, reducing traffic on the WBS.

摘要： Embedded subscriber identity module (eSIM) profile provisioning between proximate devices is described. In at least one example, a first device can broadcast expression data to one or more other devices. Based on determining a presence of a second device within a particular region, the first device can send a request for a profile associated with an eSIM of the second device to the second device. The second device can provision the profile to the first device via a direct connection with the first device. Based on receiving the profile from the second device, the first device can associate the profile with its eSIM and can access at least one service based at least in part on the profile.

摘要： Device-enabled embedded subscriber identity module (eSIM) profile acquisition is described. Server(s) associated with a service provider can receive, from an application of a device operated by a user, identification data including at least an identifier corresponding to an eSIM associated with the device. The server(s) can store an association between a profile and the identifier in a database. The server(s) can receive, from the device, a request for the profile, which can include the identifier. The server(s) can access the database to identify, based at least in part on the identifier, the association between the profile and the identifier and provision, to the device, the profile to cause the profile to be associated with the eSIM associated with the device.
