Abstract: A method and apparatus for performing a random access procedure in a narrowband internet-of-things (NB-IoT) carrier in a wireless communication system is provided. A user equipment (UE) transmits a random access preamble to a network, receives a random access response from the network, determines resources of scheduled uplink (UL) transmission, and performs the scheduled UL transmission to the network. A number of repetitions and a number of tones for the scheduled UL transmission are determined by the random access preamble.

Abstract: Techniques for dynamically scaling instances of virtual private network (VPN) gateway in a cloud computing system are disclosed herein. In one embodiment, a method includes determining whether a number of packets processed by a first instance of the VPN gateway exceeds a preset threshold. In response to determining that the number of packets exceeds the preset threshold, a new security association (SA) corresponding to a portion of the VPN network traffic is created. Upon completion of creating the SA, a load balancing policy at a load balancer is modified to forward a portion of the network traffic to a second instance of the VPN gateway when an incoming packet contains a security parameter index (SPI) corresponding to the created SA in its EPS header.

Abstract: A centralized node collects and stores radio access network (RAN) user plane congestion information (RCI) that is reported from the RAN to a core network. The centralized node provides a congestion information collection function (CICF) and includes one or more interface to communicate with a mobility management entity (MME) and/or a serving general packet radio service (GPRS) support node (SGSN). The MME and/or SGSN allows the centralized node to determine user equipments (UEs) and associated access point name (APNs) impacted by RAN congestion. The centralized node reports the RCI to a policy and charging rules function (PCRF) associated with the APNs for congestion mitigation.

Abstract: A mobile network provides first accesses implemented by a first radio access technology and second accesses implemented by a second radio access technology, which is different from the first radio access technology. A network node controls one or more of the first accesses records at least one mobility event. The mobility event corresponds to movement of a user equipment from one of the first accesses controlled by the network node to one of the second accesses. Further, the network node receives a query from a further network node. Depending on the recorded at least one mobility event, the network node responds to the query with an indication whether voice communication over packet switched access is supported for the user equipment.

Abstract: In one embodiment, a device in a network identifies a packet to be sent to a destination in the network via a path using segment routing. The device determines a list of one or more unique identifiers for one or more of the nodes along the path. The device includes a segment routing header with the packet, the segment routing header comprising a set of segment identifiers and the list of one or more unique identifiers. The device sends the packet with the segment routing header towards the destination in the network. One or more receiving nodes that receive the packet use the set of segment identifiers to route the packet towards the destination and the list of one or more unique identifiers to notify the device when the packet was not sent to the destination via the path.

More specifically, the present invention relates to triggering conditions for power headroom reporting (PHR) in a wireless network employing TDD scheme. According to one aspect of the present invention, the a user equipment (UE), receives information on a first time division duplex (TDD) uplink/downlink (UL/DL) subframe configuration, and information on a second TDD UL/DL subframe configuration informing the UE of a change from the first TDD UL/DL subframe configuration. And, the UE triggers a power headroom reporting (PHR), when the information on the second TDD UL/DL subframe configuration is received.

The first node takes a first decision whether to perform inspection of a payload section of at least one data packet of the flow at the first node and indicate a result of the first decision to the second node. The second node receives the data packets of the flow from the first node. On the basis of the result of the first decision indicated by the first node, the second node takes a second decision whether to perform inspection of a payload section of at least one data packet of the flow at the second node.

Abstract: A telecommunications system communicating data to/from one or more terminals, including one or more transmitters to transmit first and second carriers over respective first and second frequency bandwidths. During a first time period the transmitters can transmit data receivable by first and second classes of terminal on the first and second carriers. During a second different time period, the transmitters can transmit data to the second class of terminal on the first and second carriers in combination. A data transmission format on the first carrier in the first time period is incompatible with a user data transmission format on the second carrier during the first time period. The transmitters can transmit control data on the first carrier in the first time period which is receivable by the second class of terminal to enable the second class of terminal to maintain synchronization with the first carrier during the first time period.

Abstract: Apparatus and methods are provided to enhance HARQ mechanism. In one novel aspect, the UE decodes resource blocks in a HARQ indicator channel and detects a single-state HARQ indicator encoded with a UE ID of the UE. The UE determines a HARQ acknowledgment status for the data transmission based on the HARQ indicator. In one embodiment, the HARQ indicator channel is either a UE-specific channel, a group-specific channel or a cell-specific channel. In another novel aspect, the UE increases a HARQ count upon decoding the HARQ indicator channel. The UE retransmits the data transmission if the HARQ count is smaller than a predefined maximum HARQ count and the HARQ acknowledgement status is determined to be negative. Otherwise, the UE stops the data transmission. In another embodiment, the UE terminates the data transmission is the total repetition number is greater than a predefined maximum data transmission number.

Abstract: A station makes a unidirectional announcement (that is, an indication, notification or advertisement) of types of services that are available to devices in or via a wireless network, for example, a wireless local area network (WLAN). The announcement is receivable by mobile devices within radio communication range of the wireless network that are in the pre-associated state, because the announcement is conveyed using low-level layer 2 frames. A mobile device that receives such a layer 2 frame may determine the announced service type or types from the received layer 2 frame. The mobile device may determine whether it can make use of any of the announced service type or types. The mobile device may provide results of the determination to a network selection algorithm implemented at the mobile device.
