摘要:
A method for providing IDLE mode multimedia broadcast multicast service (MBMS) continuity in a telecommunication network is provided. The method includes providing an MBMS of interest for a user equipment (UE) from a first cell in the telecommunication network, using an MBMS gateway, performing a cell re-selection measurement of at least a second cell using the UE, the second cell being a neighboring cell to the first cell, wherein the cell re-selection measurement comprises determining a configuration of the second cell to facilitate an MBMS and determining a signal strength matching a predetermined strength value, and selecting one of the first cell and the second cell using the UE, which is configured to facilitate the MBMS and has a signal strength value at least equal to the predetermined strength value and greater than the other cell.

A method of and User Equipment (UE) for enhancing reporting information for a Radio Link Failure (RLF) in a Long Term Evolution (LTE) network. The method includes receiving, by a User Equipment (UE), RLF threshold information transmitted from the LTE network, logging, by the UE, the RLF threshold information, and indicating, by the UE, a recovery from a near RLF condition. The UE includes at least one means adapted for receiving an RLF threshold information transmitted from the network; logging the RLF threshold information; and indicating to the LTE network a recovery from a near RLF condition based on the RLF threshold information.

A system and method for recovering missed Multimedia Broadcast and Multicast Service (MBMS) data frames in a Multicast Broadcast Single Frequency Network (MBSFN) is provided. The method includes storing a first set of Service Data Units (SDUs) in a first Radio Link Control (RLC) buffer, wherein the first set of SDUs is broadcasted using a first set of MBMS data frames from a first eNB, storing a second set of SDUs in a second RLC buffer, wherein the second set of SDUs is broadcasted using a second set of MBMS data frames from a second eNB, and comparing the first set of MBMS data frames associated with the first set of SDUs with the second set of MBMS data frames associated with the second set of SDUs to recover the missed MBMS data frame in the first set of RLC SDUs received from the first eNB.
摘要:
Methods and apparatuses are provided for releasing a radio resource control (RRC) connection in a wireless communication network. A user equipment (UE) monitors the RRC connection. The UE performs a local RRC connection release when the UE has failed to receive an RRC connection release message from a network based on a predefined criterion. The RRC transmits an RRC connection release indication to the network. A first subscriber identity module (SIM) is transitioned from an RRC connected mode to an RRC idle mode.

A method and system are provided for a User Equipment (UE) to perform cell selection in a Cell Range Extension (CRE) region in a heterogeneous network. The method includes avoiding barring a primary frequency at a transition to an idle mode, after failing to acquire System Information (SI) from a pico cell in the heterogeneous network; and camping on a cell corresponding to one of the primary frequency and a secondary frequency.
摘要:
A method of adaptively reporting buffer status by a dual subscriber identity module dual standby (DSDS) terminal is provided. The method includes computing a rate at which uplink (UL) grants are allocated by a network over a period of time for a first subscriber unit associated with the DSDS terminal, determining a first time period to initiate buffer status reporting (BSR) using a radio frequency (RF) unit, wherein the first time period corresponds to a time period in which a BSR interval initializes, determining a second time period in which a second subscriber unit associated with the DSDS terminal requires the RF unit, and adaptively reporting the buffer status based on the rate and a difference between the second time period and the first time period.
摘要:
Apparatuses (including, but not limited to, user equipment (UE) and base stations, such as evolved Node Bs (eNBs)), systems, and methods for managing resource allocation and utilization for multi-hop device to device (D2D) communication are described. In one method, a UE sends a request to a network for a resource by which the UE can perform initial device discovery in order to perform D2D communication. If available, the network grants the resource and the UE performs initial device discovery using the resource, which includes calculating communication metrics. The UE then sends information based on the initial device discovery to the network which, based at least on that information and if available, sends back a grant for a resource for device discovery. The UE uses the grant to perform device discovery, which includes re-calculating the communication metrics.
