Abstract:
Various embodiments provide methods and apparatus for network-controlled DRVCC. In an embodiment method, a wireless user equipment may include requesting handover of a voice over Internet protocol (VoIP) call from a first network to a second network, activating a second radio, continuing the voice call on the circuit switched (CS) domain of the second network, and communicating data for applications other than the voice call via the first network. An embodiment method may include determining whether the first network supports voice-over-LTE (VoLTE) calls, and deactivating a radio in response to determining that the first network supports VoLTE calls. An embodiment method may include determining whether a quality of the VoIP call satisfies a quality threshold, deactivating the radio continued to the second network when the quality of the VoIP call satisfies the quality threshold, and activating the second radio when the VoIP call quality does not satisfy the quality threshold.
Abstract:
Systems, methods, and receiver devices enable broadcasters with restricted content license areas (e.g., Designated Market Areas (“DMAs”) to distribute content via Over the Top (“OTT”) IP networks. Embodiments enable client reporting and authentication as well as broadcast content encryption. In an embodiment, information from the client may be reported back to the broadcasters, such as a view history/use report. In an embodiment, hand off between DMAs may be enabled. In an embodiment, local advertisement insertion in network content may be enabled. Embodiments may enable Multicast-Broadcast Single Frequency Network (“MBSFN”) operation across DMA boundaries.
Abstract:
An emergency notification service is described that is delivered using an evolved multimedia broadcast-multicast service (eMBMS). An emergency notification is sent out to user equipment (UE) in affected areas. In response to receiving the emergency notification, the UE searches the appropriate emergency multicast service acquisition information for multiple potential types of available emergency content that is provided by the eMBMS system in the network and tunes to the eMBMS to receive the emergency content. In selected aspects, the transmitted information, including the notifications and content may be scrambled using the same cell ID for each of the cells transmitting the same content. This improves the quality of the transmitted signals allowing for more reliable receipt and decoding by the receiving UEs.
Abstract:
A method, an apparatus, and a computer program product for wireless communication at a node are provided. The apparatus receives a multicast-broadcast single frequency network (MBSFN) signal transmitted from a base station, decodes the received MBSFN signal, and retrieves at least one source symbol from the decoded MBSFN signal when the node is capable of retrieving a source symbol. The apparatus also generates at least one redundancy version of the MBSFN signal based on the retrieved at least one source symbol and transmits the at least one redundancy version of the MBSFN signal via MBSFN. Generating a redundancy version of the MBSFN signal includes applying forward error correction (FEC) on the retrieved at least one source symbol to generate at least one repair symbol. Thus, a redundancy version of the MBSFN signal includes the at least one repair symbol and a subset of the at least one source symbol.
Abstract:
A method, an apparatus, and a computer program product for wireless communication are provided. In a first configuration, the apparatus is an eNB. The eNB constructs an MCCH change notification, and sends the MCCH change notification with a carrier frequency index for a first frequency of a first cell on a second frequency of a second cell. In a second configuration, the apparatus is a UE. The UE receives a configuration with aggregated carriers including a primary carrier from a primary cell and one or more secondary carriers from one or more corresponding secondary cells, and receives an MCCH change notification with a carrier frequency index for a first frequency of a first cell on a second frequency of a second cell. The first cell and the second cell are each one of the primary cell and the secondary cells.
Abstract:
Compression of broadcast data packets is described in which a compressed broadcast data packet is formed by causing at least one field in a packet header to be excluded from the transmitted data packet. The data from the compressed or removed field is data that is otherwise available to a user entity. The user entity receives the compressed broadcast data packet and determines information corresponding to at least one of the eliminated fields in order to process the received broadcast information.
Abstract:
Methods and devices for communicating in a communication system are described herein. In one aspect, methods and devices for group based access control of machine to machine devices for wireless communication are described. One method includes forming a machine-to-machine (M2M) group identifier based on a M2M service category. The method further includes associating the M2M group identifier with at least one wireless device. The method further includes transmitting data intended for receipt by the M2M group, the data including the M2M group identifier.
Abstract:
Techniques are provided for smooth transition between broadcast/multicast transmission and unicast transmission. A method for managing unicast and multicast services switching in a multi-band/multi-frequency wireless communications system (WCS) capable of both unicast and multicast signaling includes determining whether an aggregate demand for a content provided via dedicated unicast transmissions exceeds a threshold. The method includes switching transmission of the content from the dedicated unicast transmissions on one frequency to a multicast transmission on a second or more frequencies in response to determining that the aggregate demand exceeds the threshold.
Abstract:
Techniques are provided for receiving one or more representations of content wirelessly. The method may involve receiving a media presentation description (MPD) that includes parameters for reception of data segments for multiple representations of content via broadcast transmission and unicast transmission. The method may involve determining whether the broadcast transmission or the unicast transmission is appropriate for reception of the data segments, and selecting a given representation from among the multiple representations of the content based on a criteria of the mobile entity. The method may involve receiving the data segments for the given representation based at least in part on the parameters for the determined one of the broadcast transmission and the unicast transmission.
Abstract:
Access terminals are adapted to facilitate use of modified cell reselection parameters and/or procedures for access terminals exhibiting low or no mobility. An access terminal may employ one or more mobile thresholds to determine whether to perform cell reselection when the access terminal is mobile, and one or more stationary threshold to determine whether to perform cell reselection when the access terminal is stationary or substantially stationary. Methods operational on access terminals include determining the access terminal to be stationary or substantially stationary, and employing one or more stationary thresholds to determine whether to perform a cell reselection when the access terminal is determined to be at least substantially stationary. Other aspects, embodiments, and features are also included.
