  • Publication number: 20190028943
    Abstract: A network may implement a method to support a mobility of a wireless transmit/receive unit (WTRU). The network or network functions may identify the WTRU that is associated with one or more capabilities and one or more mobility properties. The network or network functions may determine subscription information and network policy information for the WTRU. The network or network functions may select a mobility pattern for the WTRU based on the one or more capabilities and the one or more mobility properties associated with the WTRU, the subscription information, and the network policy information. The mobility pattern may be associated with a mobility parameter and a value corresponding to the mobility parameter.

  • Patent number: 10165389
    Abstract: Systems, methods, and instrumentalities are provided to determine routing associated with a short message. A SMS-SC may send a first routing request to a home subscriber server (HSS). The first routing request may be associated with the short message. The SMS-SC may receive a first routing reply. The first routing reply may include one of an indication that the short message is associated with a service capability server (SCS) or a first control plane routing associated with the short message. The SMS-SC may send the short message to an SCS serving node. The first routing reply may include the indication that the short message is associated with a service capability server (SCS). The SMS-SC may send a second routing request to a SCS subscription database. The SMS-SC may receive a second routing reply from the SCS subscription database, which may indicate a second control plane routing for the short message.

  • Patent number: 10129802
    Abstract: Techniques and devices are disclosed for efficient offloading and/or aggregation of resources by providing different levels of connection management in a network. A wireless transmit/receive unit (WTRU) may support additional ECM and/or RRC states (e.g. inactive states) and/or transitions that may enable a WTRU to act without an RRC connection and/or with reduced latency. A WTRU may operate with network resources with and/or without radio resources. A WTRU may operate in parallel with a plurality of layers, including a primary layer for which the WTRU may behave according to LTE or other behavior. The WTRU may be configured for operation in a secondary layer. The WTRU may establish a secondary layer security context and/or a tunnel or routing for the secondary layer for transport of user plane data between the WTRU and a gateway. The WTRU may determine to which layer uplink data may be applicable.

  • Patent number: 10117220
    Abstract: A method and apparatus for machine type communication (MTC) authentication and triggering may be performed by an MTC interworking function (MTC-IWF). On a condition an Internet protocol (IP) connection does not exist between a services capability server (SCS) and an MTC device, a device trigger message may be received by the MTC device over a Tsp interface. The device trigger message may include a cryptographic key and may have an associated level of urgency. The method may further comprise determining a level of network congestion and transmitting the device trigger, including the received cryptographic key, to the MTC device in accordance with the associated level of urgency. A report may be sent to the SCS, associated with the determined level of network congestion, to indicate either success or failure of the device triggering procedure. The received cryptographic key may be used to secure an IP connection.

  • Publication number: 20180302946
    Abstract: Current wireless networks do not allow machine type communication (MTC) devices to have long discontinuous reception (DRX) cycles or sleep lengths. A long DRX cycle may allow MTC systems and devices to operate with much longer DRX/Sleep cycles/periods. This may facilitate the MTC operations for infrequent system access or infrequent system reaching (e.g. paged once in a week) with no or low mobility and may allow MTC devices to sleep for a long time with low power consumption.

  • Patent number: 10104576
    Abstract: A method and apparatus are described for controlling the application of Selected Internet Protocol (IP) traffic offload (SIPTO) or Local IP Access (LIPA) services for a wireless transmit/receive unit (WTRU). The SIPTO and LIPA services may be performed over packet data network (PDN) connections. A user of the WTRU may be prompted to accept or reject the usage of the SIPTO or LIPA services. The user of the WTRU may request switching from SIPTO or LIPA services to non-SIPTO or non-LIPA services.

  • Patent number: 10091723
    Abstract: Methods and apparatus may be used for selecting power saving mechanisms in a wireless transmit/receive unit (WTRU). For example, a WTRU may support at least power saving mode (PSM) and/or extended discontinuous reception (eDRX) mode. The WTRU may send a request message including parameters associated with the supported power saving mechanisms, such as an active time for PSM and a preferred DRX value for eDRX mode. The WTRU may receive an accept message including at least one selected parameter indicating the power saving mechanism for the WTRU selected by the network (NW). The WTRU may activate the selected power saving mechanism, and may start a validity timer to define the duration of use of the selected power saving mechanism. In another example, a WTRU configured to use eDRX may receive paging signals for system information (SI) change over a prolonged Broadcast Control Channel (BCCH) modification period.

  • Publication number: 20180220343
    Abstract: A method and apparatus are provided for updating a sequence hopping (SH) pattern of an uplink channel during handover from a current cell having a current SH pattern. At least one downlink channel of each neighbor cell of the current cell is monitored. Information indicative of the monitored downlink channels of the neighbor cells is transmitted to the current cell. Prior to receiving a handover command from the current cell a target cell from among the neighbor cells is anticipated and a common downlink channel of the anticipated target cell is monitored to determine information representative of a target SH pattern of the target cell.

  • Patent number: 10009939
    Abstract: A method and apparatus are described for providing non-packet switched service to a target radio access technology (RAT) network. A circuit switched (CS) service notification message is received by a wireless transmit/receive unit (WTRU). If the WTRU has been allocated a valid temporary mobile subscriber identity (TMSI), a paging response message including the valid TMSI is transmitted after an inter-system change is performed from a source RAT network to a target RAT network. The CS service notification message is for terminating a CS call request. The source RAT network may be a long term evolution (LTE) network, and the target RAT network may be a third generation partnership project (3GPP) network. Alternatively, if the WTRU has not been allocated a valid TMSI, a paging response message including an international mobile subscriber identity (IMSI) that identifies the WTRU is transmitted after the inter-system change.

  • Patent number: 9986514
    Abstract: Method and apparatus are disclosed for determining a physical uplink power level for transmissions on a physical uplink channel. In one embodiment, a random access channel (RACH) uplink message is transmitted. The RACH uplink message includes a RACH message power level and/or a downlink pathloss figure. A downlink message including a power offset value is received. The physical uplink power level is set for transmissions on the physical uplink channel based on the power offset value. In another embodiment, a RACH uplink message is transmitted and a downlink message including a relative power offset value is received. The physical uplink power level for transmissions on the physical uplink channel is then set based on the relative power off set value.
