摘要:
Methods and apparatuses are provided that include enhancing decoding of multicast broadcast control communications, which can be of a relatively large size. A configuration message related to a broadcast channel structure can be received in multiple instances and/or segmented data units. A receiver can combine multiple instances and/or accumulate segmented data units to obtain and/or decode a control channel over which the configuration message is communicated. Communicating segmented data units of the configuration message can allow a broadcast station to utilize a lower data rate, more reliable modulation and coding scheme to encode the configuration message.

A method enables a user equipment (UE) intervention to reduce a network-initiated Quality of Service (QoS) interruption time or a disruption of the network-initiated QoS, while avoiding application intervention. The method includes communicating with a source radio access network (RAN) in accordance with a network-initiated quality of service (QoS) profile. The method also includes transferring to a target RAN. The method further includes triggering, by a user equipment (UE), a QoS setup to reestablish the QoS profile.

Disclosed are systems, methods and computer program products for performing multiple registrations across different radio access technologies (RATs). In one aspect, the registration procedure provisions a mobile device to register with a primary RAT and pre-register with at least one non-primary RAT using its air interface, which is different from the primary RAT. The pre-registration procedure includes setting up a radio session context and a packet data network (PDN) context with the non-primary RAT. The procedure further includes setting up a pseudo-binding with an external PDN gateway and obtaining binding state information for the mobile device from the PDN gateway without transferring binding state from the primary RAT to the non-primary RAT. The binding state information may be added to the PDN context. The mobile device may then perform handoff from the primary RAN to non-primary RAN using the preset contexts.

Aspects of the present disclosure provide techniques to speed up and improve silent redial success rates in wireless communications. A user equipment (UE) may determine how to attempt retrying a mobile originated (MO) call and procedures for selecting a subsequent system for attempting the call based, at least in part, on a restriction status of the call and a detected failure.

Systems and methodologies are described that effectuate establishment of an IPSec tunnel for utilization in a wireless communication environment. IPSec establishment procedures on home base stations can be used to establish IPSec tunnels between home base stations situated on open access sectors of wireless communication environments and packet data interworking function components positioned at the contiguity of secured segments of the wireless communication environments. Moreover, high rate packet data point-to-point protocol challenge-handshake authentication protocols can be directed through the IPSec tunnels to facilitate authentication of access terminals associated with the home base stations in order to facilitate further communications with components dispersed within secure areas of wireless communication environments. Further, international mobile subscriber identities (IMSI) affiliated with access terminals associated with home base stations can be used to identify packet data serving nodes with which to establish communications between home base stations and packet data serving nodes.
摘要:
Internet protocol (IP) continuity is fundamentally not possible when a user equipment (UE) moves from an evolved packet core (EPC) radio access technology (RAT) to a non-EPC RAT. However, there are instances when it is beneficial to not completely release an EPC IP context, such as when the UE moves to the non-EPC RAT for only a short period of time. The UE may retain an EPC IP context in a suspended state while the UE is in the non-EPC RAT, and revive the context when the UE returns to the EPC RAT. Accordingly, a method, an apparatus, and a computer program product for maintaining an EPC context at a UE are provided. The apparatus suspends and retains the EPC context when moving from an EPC capable network to a non-EPC capable network, and resumes the suspended EPC context upon returning to the EPC capable network.

Aspects disclosed herein relate to enabling fallback to a second data service based on whether one or more fallback conditions are present before or during establishing a data context with a first data service. In one example, a UE may be configured to determine whether one or more fallback conditions are present before or during establishing a data session with a first data service. The UE may be further configured to prohibit further attempts to establish a data context to access the first data service based on the determination of the presence of at least one of the one or more fallback conditions. Some aspects disclosed herein relate to enabling fallback to a HRPD data service based on whether one or more fallback conditions are present before or during establishing a data context with an eHRPD data service.
摘要:
Systems, methods and apparatus for non-optimized handoffs for wireless communication are provided. For example, the disclosure may be applied to enhance non-optimized handoff from a long-term evolution (LTE) network to an evolved high rate packet data (eHRPD) network. Systems, methods, and apparatus for reducing the interruption gap during handoffs from an LTE radio access network to an eHRPD network are also discussed. In one aspect, a method is provided for communicating information associated with a handoff of a wireless device from a source network to a target network. The method includes, during a period of data inactivity, attaching to a first network and creating a context therewith, the first network being a non-preferred network as compared to a second network. The method also include connecting to the second network based on the context created with the first network and while maintaining at least a partial context with the first network.

摘要:
Techniques for scheduling logical channels for data transmission are described. In one design, a user equipment (UE) is configured with a plurality of logical channels for sending data on the uplink. Each logical channel is associated with a priority and a data buffer size. The UE maintains a token bucket for each logical channel. In each scheduling interval or when an uplink grant is received, the UE determines a bucket level (which may be a positive value or a non-positive value) for each of the plurality of logical channels. The UE ascertains logical channels with bucket levels of the same polarity and then identifies logical channels of the same priority among all logical channels with the same bucket level polarity. The UE selects at least one identified logical channel for scheduling based on the data buffer size and/or the bucket level for each identified logical channel.
