Abstract: A time synchronization system comprises a time master, a time slave, and a management node which are coupled to one another via a plurality of networks. The time master transmits to the time slave a time packet at a given timing through at least one of the plurality of networks. The time slave has a time correcting part for receiving the time packet transmitted from the time master and for correcting time based on the received time packet. The management node has: a network switching determining part for determining whether to switch the network for transmitting a time packet to another of the plurality of networks; and a network switching notifying part for notifying, in a case where it is determined that the network for transmitting the time packet is to be switched, information for identifying the switched-to network to the time slave.

Abstract: When a UE in an LTE system enters the RRC_IDLE state, only the S5/S8 EPS bearer context is retained, and the S1-U, S1-AP and radio bearers are released. These bearers have to be re-established on per UE basis when the UE returns to RRC_CONNECTED state. A number of UE applications may send small data frequently, which causes the UE to toggle between IDLE and CONNECTED states. This leads to a great deal of signaling overhead as the radio bearer and the S1-U bearer must be frequently re-established as the UE transitions between IDLE to CONNECTED states. Described herein are methods and systems that provide an always-on S1-U bearer to reduce this signaling overhead.

Abstract: A method for retransmitting data in wireless communication system is disclosed. MS can receive a NACK (Not-Acknowledge) signal from a base station (BS) through a specific downlink subframe of a specific frame in a first superframe, and the MS can retransmits the data using a second uplink subframe in a first frame in a second superframe subsequent to a first superframe. In this case, a index of the second uplink subframe may be 1. The wireless communication system can support the Half-Frequency Division Duplex (H-FDD) scheme. A first uplink subframe in the first frame of the second superframe can be punctured.

Abstract: The present disclosure proposes a dynamic time division duplexing (TDD) method applicable to a user equipment and a control node, and apparatuses using the same method. Accordingly, the present disclosure proposes a base station (BS) which transmits to a least one user equipment (UE) a system information block (SIB) having a first modification period, and the base station may transmit a TDD uplink-downlink subframe configuration during the first modification period. The BS also configures for at least one UE a second modification period which is in an integer divisor of the first modification period and could be within the first modification period so that the BS may transmit a second TDD uplink-downlink subframe configuration in the second modification period. As the second modification period is shorter than the first modification period and is periodically scheduled, the BS may alter the current TDD uplink-downlink subframe configuration dynamically at a faster rate.

Abstract: Adaptive neighboring cell measurement scaling by a wireless user equipment (UE) device. The UE may operate alternately in active and inactive states in a periodic manner according to DRX cycle timing for each of a plurality of DRX cycles. Paging messages may be checked for while in the active state during each DRX cycle. If a paging message is received, it may be decoded using a joint detection technique. The UE may adaptively determine whether or not to perform neighboring cell measurements during at least a subset of the DRX cycles, and perform neighboring cell measurements according to the adaptive determination. The adaptive determination may be based on one or more of joint detection of paging messages, one or more previous cell measurements, or an amount of motion of the UE.

The time weight increases with increasing link stability indicated by the statistic.

Abstract: In accordance with one aspect of the invention, a process for handling emergency calls from a caller in a voice over IP system is described. The process involves receiving a routing request message including a caller identifier and a callee identifier. The process also involves setting an emergency call flag active in response to the callee identifier matching an emergency call identifier pre-associated with the caller. The process further involves producing an emergency response center identifier in response to the emergency call identifier. The process also involves determining whether the caller identifier is associated with a pre-associated direct inward dialing (DID) identifier. The process further involves producing a direct inward dialing (DID) identifier for the caller by associating a temporary DID identifier with the caller identifier when the emergency call flag is active and it is determined that the caller has no pre-associated DID.

Abstract: A wireless feeder network comprises feeder base stations coupled to the communications network and feeder terminals coupled to associated access base stations of the access network. A group of wireless network components form elements of a feeder cluster and the elements of the feeder cluster are connected by an additional communications resource configured to be operated in parallel with the wireless resource of the wireless feeder network. Both a primary and secondary element of the feeder cluster seek to decode at least one resource block allocated to the primary element for reception of data. Information derived from the secondary decoded data is transmitted from the secondary element to the primary element via the additional communications resource. The primary element then performs a revised decoding process additionally using the information received from said secondary element to improve its own decode probability.

Abstract: Techniques are identified for optimizing the MAC flush in Ethernet rings for faster traffic restoration. In one embodiment, flushing of MAC addresses is performed only once on receiving a first control message. For example, when a first control message is received, a network device may switch from a first state to a second state, which may indicate that the MAC addresses are not to be flushed if additional control messages are received. In another embodiment, flushing of MAC addresses is performed on one ring port rather than on both ring ports. For example, a flag field of a control message header may be used to determine on which port to flush. In another embodiment, flushing of MAC addresses is performed on only one ring port of an interconnection node. For example, the ring port can be determined using a flag field and possibly labels associated with the ring ports.

Abstract: A User Equipment (UE) for performing carrier aggregation is described. The UE includes a processor and instructions stored in memory that is in electronic communication with the processor. The UE determines a duplex method of each serving cell for frequency-division duplexing (FDD) and time-division duplexing (TDD) carrier aggregation. At least one serving cell is a TDD cell and at least one serving cell is a FDD cell. The UE also determines physical downlink shared channel (PDSCH) Hybrid Automatic Repeat Request Acknowledgement/Negative Acknowledgement (HARQ-ACK) transmission timing for a serving cell. When a primary cell is a TDD cell, the PDSCH HARQ-ACK transmission timing for the serving cell is determined based on a downlink (DL) association set for the serving cell. The UE further sends PDSCH HARQ-ACK information based on the PDSCH HARQ-ACK transmission timing.

Abstract: One embodiment of the present invention provides a switch. The switch comprises one or more ports, a link management module and a load balancing module. The link management module operates a port of the one or more ports of the switch in conjunction with a remote switch to form a virtual link aggregation. The load balancing module generates an index of a weight distribution vector based on address information of a multicast group associated with the virtual link aggregation. A slot of the weight distribution vector corresponds to a respective switch participating in the virtual link aggregation. In response to the index indicating a slot corresponding to the switch, the load balancing module designates the switch as primary switch for the multicast group, which is responsible for forwarding multicast data of the multicast group via the virtual link aggregation.
