摘要： A first network device receives an authentication request, from a second network device, to authenticate a user device and a first over-the-top application, stored on the user device, to determine whether to apply a level of quality of service to the first over-the-top application. The first network device authenticates the user device, based on the authentication requested. The first network device authenticates the first over-the-top application, based on the authentication request. The first network device sends an authentication result, based on the authentication of the user device and the first over-the-top application, to the second network device; and the second network device initiates, based on the authentication result, a process to apply a level of quality of service to information sent between the first over-the-top application and a provider associated with the first over-the-top application.

摘要： A user equipment (UE) provides for display, to a user, information identifying available over-the-top (OTT) services provided via voice-over-Long-Term Evolution (VoLTE), and receives, from the user, a selection of a particular OTT service of the available OTT services. The UE receives, from the user, information identifying a selected contact associated with the particular OTT service, and determines whether a particular UE associated with the selected contact is a VoLTE capable device or a non-VoLTE capable device. The UE provides a call to the particular UE, via a LTE network and an Internet protocol (IP) Multimedia Subsystem (IMS) network, when the particular UE is a VoLTE capable device.

摘要： A code division multiple access communication system receiver includes block-based chip timing estimation. A chip timing estimate is generated from samples of a received signal by performing an averaging operation over a designated block of chips in each of first and second legs of an early-late synchronizer. The chip timing estimate is determined as a function of an error signal corresponding to the difference between outputs of the first and second legs, and is utilized to adjust a code generator clock or to otherwise control chip timing in the receiver. In an illustrative embodiment, a separate block-based chip timing estimator is implemented in each of the fingers of a Rake receiver.
