摘要： An apparatus and a method are provided for improving user experience in a multi-radio access bearer (multi-RAB) wireless communication system. After a user equipment establishes a circuit-switched communication link and a packet-switched communication link with a core network, it may receive an indication of an error associated with the packet-switched communication link. Here, if the value of a timer such as the RAB re-establishment timer T314 has a predetermined value (e.g., 0), the user equipment may release the packet-switched communication link, and maintain the circuit-switched communication link. The packet-switched communication link may then be re-established. In this fashion, errors that may occur on the data call need not interrupt a voice call.

摘要： Methods and apparatuses for improved uplink establishment in wireless networks are presented. For example, a method of mobile communication at a user equipment is presented that may include receiving, at a user equipment (UE) and from a network entity, configuration information associated with an enhanced uplink in CELL_FACH state protocol, wherein the UE is configured to transmit uplink transmissions according to the enhanced uplink in CELL_FACH state protocol. Additionally, the example method may include determining that the configuration information includes invalid configuration information. Moreover, the example method may include performing at least one remedial action to ensure that the UE is able to transmit the uplink transmissions based on determining that the configuration information includes invalid configuration information.

摘要： Methods, systems, and devices are described for handling over-sized call setup messages are disclosed. A user equipment (UE) may identify the size of a connection setup message (e.g., RRC connection setup complete message) associated with one or more UE capability information. Based on the identified size of the connection setup message, the UE may determine an estimated time required to transmit the connection setup message to a network entity (e.g., base station) over at least one uplink channel and determine whether the estimated time is above or below a threshold. If the UE determines that the estimated time to transmit the connection setup message is greater than the threshold, the UE may remove at least a portion of the connection setup message and transmit a modified connection setup message.

摘要： Various aspects of the present disclosure enable a plurality of mobile devices (UEs) within a cell to spread out in time their respective transmissions of signaling messages, such as cell update messages, when the network enables or disables enhanced uplink (EUL, sometimes referred to as high-speed uplink packet access or HSUPA) while the UE is in the CELL_FACH state, by changing SIB5 or SIB5bis. In this way, the network load may be reduced, and a network blockage that otherwise might result from large numbers of UEs simultaneously transmitting the cell update message can be avoided. According to one example, a network node may be configured to distribute CELL_UPDATE messages or procedures to UEs when the network node enables or disables EUL in CELL_FACH by changing SIB5 or SIB5bis over time to reduce the network load. According to another example, a UE may be configured for utilizing a random timer or back-off timer to defer cell updates.

摘要： In a particular embodiment, a method includes sending a message from a communication device to a radio network controller. The message indicates that a data session has ended. The data session is supported by a wireless channel between the communication device and the radio network controller. After a time period following the sending of the message, a second message is selectively sent to the radio network controller. The second message indicates that the data session has ended. The second message is selectively sent based at least in part on whether a measurement indicates that data was communicated via the wireless channel during the time period.
