Abstract: Systems and methodologies are described that facilitate selectively and simultaneously establishing multiple bearers in wireless communication networks. A core network entity in a wireless network can transmit a bearer establishment request to an access point comprising a list of bearers to establish with a related mobile device. The bearer establishment request comprising list of bearers includes separate non-access stratum (NAS) messages corresponding to each bearer in the list. The separate NAS messages can be linked to each bearer entry in the list. The access point can receive the list and attempt to initialize one or more radio bearers in the list. Since the NAS messages individually correspond to a given bearer, the access point can forward NAS messages to the mobile device only for bearers that are successfully initialized allowing selective establishment thereof. In addition, the access point can provide initialization status for the individual bearers to the core network.

Abstract: Systems and methodologies are described that facilitate network management and optimization. As described herein, a network and a device communicating with the network can exchange network management information, thereby supporting a Self Organized Network (SON) architecture for improved network management and optimization performance. A Non-Access Stratum (NAS) layer protocol and/or an Internet Protocol (IP) application, in combination with a set of associated network management messages, can be utilized to exchange network management information between a device and a network. As further described herein, various procedures can be utilized to install a SON policy to a device in order to define device behavior for operations such as collecting and reporting information related to network management. Additionally, a set of standardized events can be defined, based on which a device can detect the occurrence of an event and report the occurrence to an associated network.

Abstract: Methods and apparatus are provided for device configuration (e.g., feature segment loading and system selection). Certain aspects of the present disclosure generally relate to operating a user equipment (UE) in a first radio access network (RAN) with a first set of modem features that supports the first RAN, detecting a second RAN not supported by the first set of modem features, and rebooting the modem software to load a second set of modem features that supports the detected RAN. For certain aspects, the first RAN may be a Time Division-Synchronous Code Division Multiple Access (TD-SCDMA) network and the second RAN may be a Wideband-Code Division Multiple Access (W-CDMA) network or Long-Term Evolution (LTE) network. This allows features to be loaded into memory (e.g., only) when they are required to support a detected RAN, rather than loading an entire image, thereby conserving DRAM and increasing efficiency.

Abstract: Transmission techniques are provided that improve service continuity and reduce interruptions in delivery of content that can be caused by transitions that occur when the User Equipment (UE) moves from one cell to the other, or when the delivery of content changes from a Point-to-Point (PTP) connection to a Point-to-Multipoint (PTM) connection in the same serving cell, and vice-versa. Such transmission techniques enable seamless delivery of content across cell borders and/or between different transmission schemes such as Point-to-Multipoint (PTM) and Point-to-Point (PTP). Mechanisms for adjusting different streams and for recovering content from each data block during such transitions are also provided so that data is not lost during a transition. In addition, mechanisms for realigning data during decoding at a receiving terminal are also provided.

Abstract: Feedback from user stations to the base station for a multicast/broadcast transmission is performed by decoding multicast/broadcast data received from a transmitter on a downlink resource, forming a feedback message corresponding to the reception of the multicast/broadcast data, and queuing the feedback message for transmission to the transmitter on an uplink resource. The uplink resource used corresponds to the downlink resource used for the multicast/broadcast transmission. For unicast transmissions the uplink resource is dedicated to an uplink transmission corresponding to a downlink transmission on the downlink resource.

Abstract: Facilitating user terminal (UT) access to wireless networks having base stations (BSs) of disparate access types is described herein. In some aspects, BS parameterization is provided to facilitate search and/or access to distinct types of network BSs. For instance, parameters can modify a likelihood of identifying or remaining coupled to restricted access (RA) BSs in a home Node B (HNB) deployment. In other aspects of the subject disclosure, a PLMN ID reserved for HNBs is provided comprising multiple region IDs. Where a UT identifies a home region, HNBs can be given preference over macro BSs. Additionally, the UT can keep track of HNBs and HNB regions that reject access to the UT, and implement a delay time to mitigate rapid signaling to foreign HNBs in a dense HNB deployment. Accordingly, the subject disclosure provides for more efficient UT access in heterogeneous access type networks.

Abstract: Techniques for performing in-order data delivery during handover in a wireless communication system are described. A user equipment (UE) may perform handover from a source base station to a target base station. The target base station may start a timer after a data path from a gateway to the UE has been switched from the source base station to the target base station. The target base station may receive forwarded packets for the UE from the source base station and may receive new packets for the UE from the gateway. The target base station may send the forwarded packets received prior to expiration of the timer to the UE before any new packets. The target base station may send the forwarded packets to the UE without waiting for the timer to expire and may send the new packets to the UE after the timer expires.

Abstract: Techniques for performing inter-system handover are described. An Access Gateway (AGW) sends a message requesting handover of a user equipment (UE) from a first radio access network (RAN) to a second RAN. The message is sent to an Inter Access System (inter-AS) Anchor for the first RAN communicating with an SGSN for the second RAN via a Gn interface. The Inter-AS Anchor and SGSN exchange messages via the Gn interface, and the Inter-AS Anchor forwards the messages to the AGW to handover the UE from the first RAN to the second RAN. The SGSN sees the Inter-AS Anchor as another SGSN for the handover and as a GGSN after the handover. This allows the inter-system handover to be achieved with an inter-SGSN SRNS relocation procedure used for handover between two SGSNs, which reduces impact on the SGSN to support the inter-system handover.

Abstract: Schemes to time-align transmissions from multiple base stations to a terminal. To achieve time-alignment, differences between the arrival times of transmissions from the base stations, as observed at the terminal, are determined and provided to the system and used to adjust the timing at the base stations such that terminal-specific radio frames arrive at the terminal within a particular time window. In one scheme, a time difference between two base stations is partitioned into a frame-level time difference and a chip-level time difference. Whenever requested to perform and report time difference measurements, the terminal measures the chip-level timing for each candidate base station relative to a reference base station. Additionally, the terminal also measures the frame-level timing and includes this information in the time difference measurement only if required. Otherwise, the terminal sets the frame-level part to a predetermined value (e.g., zero).

Abstract: Techniques for performing handover in order to maintain call continuity for a user equipment (UE) are described. The UE may communicate with a first cell in a radio access network (RAN) for a packet-switched (PS) call, e.g., for Voice-over-Internet Protocol (VoIP) via High-Speed Packet Access (HSPA) in W-CDMA. The UE may send measurement reports to the RAN and may receive trigger from the RAN. The UE may establish a circuit-switched (CS) call with the first cell while the PS call is pending at the first cell. The PS call and the CS call may be for a voice call, and the UE may switch data path for the voice call from the PS call to the CS call and then terminate the PS call. The UE may then perform handover of the CS call from the first cell to a second cell, which may not support VoIP.

Abstract: An apparatus, method, processor(s), and computer program product avoids user data loss by network-controlled, user equipment assisted handover in a wireless data packet communication system. A wireless receiver receives radio link control (RLC) packet data units (PDUs) from user equipment (UE) being served by a source node. A wireless transmitter commands the UE to handover. A network communication interface transmits RLC Uplink (UL) context from the source node to the target node, and transmits RLC Downlink (DL) initialization message and buffered in-transit DL RLC PDUs from the source node to the target node.

Abstract: According to one aspect, a method that includes some of the teachings of the present subject technology reduces congestion in a communications network. The method includes, inter alia, letting a persistence value be a function of N, even when ASC=0, and also a function of a constant the emergency services access parameter W, such that the persistence value P0(N) ranges between P1(N) and 1 when the emergency services access parameter W ranges from a first value (e.g. 0) to a second value (e.g. 1), where P(N)=2?(N?1) and where N is transmitted in a system information message. A comparator allows a user to access the communications network only if a random/pseudorandom number is less than the persistence value. Other aspects, such as a computer program product, also reduce congestion in a communications network.

Abstract: Techniques for sending data during handover with Layer 2 tunneling are described. In one design, a user equipment (UE) sends first Layer 2 packets to a source base station prior to handover to a target base station. The UE sends at least one second Layer 2 packet to the target base station, which identifies the second Layer 2 packet(s) as being intended for the source base station and thus forwards the second Layer 2 packet(s) to the source base station via a Layer 2 tunnel. The UE sends third Layer 2 packets to the target base station after the handover. The target base station processes the third Layer 2 packets to obtain IP packets and sends the IP packets to a serving gateway after a trigger condition, which may be defined to achieve in-order delivery of IP packets from the source and target base stations to the serving gateway.

Abstract: Methods and apparatus are described for broadcasting content. Encoding the content to be multicast/broadcast into multiple streams, wherein at least one stream provides a base portion of the content, and additional streams provide enhancements to the content. A wireless communication device receives the broadcast and decodes streams in accordance with the reception capabilities of the wireless device. The configuration of the wireless device can be determined based on the wireless device's capability to decode multiple streams. In addition, the configuration of the wireless device can be determined based on a subscriber level of the wireless device.

Abstract: A novel and improved method and apparatus, in a WCDMA communication system, for informing a mobile station of a downlink data frame time offset by determining the downlink data frame time offset, and transmitting the downlink data frame time offset via an Active Set Update message transmitted from a cell to mobile station. Once an Active Set Update message is received, the data frame time offset information is provided to a timing block which may determine data frame boundary of each downlink signal. Timing block may then adjust the PN sequence timing corresponding to the downlink signal associated with the data frame time offset such that corresponding data symbols in each data frame are correctly soft combined in a combiner.

Abstract: Systems and methodologies are provided that facilitate security activation for wireless communications. In an aspect, a method for wireless communication is provided which includes determining a first security key for communicating with a source access point and receiving, from the source access point, a handover command that includes an indication of whether to apply a second security key upon handover. The method also includes handing over communication from the source access point to a target access point, where the second security key is applied for communicating with the target access point upon the handover when the handover command indicates to apply the second security key.

Abstract: Aspects relate to allowing a mobile device to discover missing neighbor cell relations when there is a radio link failure. At substantially the same time as connecting to a new cell that utilizes the same radio link technology, the failure is reported. If a connection is reestablished with a cell that utilizes a different radio link technology, the radio link failure information (and related missing neighbor information) is retained and reported later when a connection with a cell that utilizes the same radio link technology is established.
