摘要:
A machine-to-machine (M2M) gateway (GW) includes reachability, addressing, and repository (RAR) capability. The GW maintains a local mapping table and local device application repository, performs data aggregation, address/name translation, provides event reporting and establishes GW reachability and wake-up time. The GW supports requests from M2M applications or other capabilities within the GW, and from a network and application (N&A) domain RAR. The GW may include an M2M device and M2M gateway management (MDGM) capability that receives management requests for an M2M device and functions as a network proxy. The MDGM accepts and processes requests from the N&A domain on behalf of the M2M device and performs management functions of the M2M device on behalf of the N&A domain. The MDGM may request the N&A domain for permission to interact with the M2M device, initiate an interaction for device management tasks with the M2M device, and report to the N&A domain.

Disclosed herein are method embodiments and apparatus embodiments for allocating IP addresses for MTC devices, transmitting and receiving SMS using the allocated IP addresses. In an embodiment, the MTC device may be allocated with an IP address without activating a packet data protocol (PDP) context. In addition, after the IP address has been allocated, SMS messages may be transmitted from and to MTC devices using the IP address.
摘要:
A method and apparatus for supporting machine-type communications (MTC) are disclosed. A wireless transmit/receive unit (WTRU) may configure itself to operate in a mobile-originated-only mode. The WTRU may perform no, or a subset of, radio resource control (RRC) idle and/or non-access stratum (NAS) idle/standby state procedures in the mobile-originated-only mode. For example, the WTRU may perform cell reselection but not paging monitoring in the mobile-originated-only mode. Alternatively, the WTRU may perform paging monitoring but not cell reselection and location update. The operation in the mobile-originated-only mode may be triggered explicitly or implicitly. For example, the WTRU may operate in the mobile-originated-only mode if an inactivity timer expires. The WTRU may switch the mode in accordance with a pre-configured schedule. After transition of the operation mode, the WTRU may send a message to the network indicating such mode switch.

Method of and apparatus for searching for enhanced dedicated channel transport format combinations (E-TFCs) in a table is disclosed. A transmission time interval (TTI) and an E-TFC data are received. An appropriate E-TFC table is selected based on the received TTI and E-TFC data. The E-TFC table is split into a plurality of sub-tables. All the E-TFCs in each of the sub-tables have the same maximum power reduction value and are continuous in the table. Each sub-table is searched.
摘要:
Method and apparatus for supporting machine-to-machine (M2M) communications in a hierarchical network architecture including an M2M gateway are disclosed. An M2M entity, (such as M2M device, M2M gateway, or M2M network entity), may perform a service capability discovery procedure to discover an M2M service capability entity that may provide an M2M service capability, and register with the discovered M2M service capability entity. The address or identity of the service capability entity may be pre-configured or obtained from the dispatcher server. The M2M entity may indicate a support M2M service identifier and receive an identity or address of the M2M service capability entity mapping the service identifier. The gateway may advertise M2M service identifiers supported by the gateway so that the M2M device may access the gateway if there is a match. The address of M2M service capability entities may be obtained from the core network.
摘要:
Technology for communicating small data between a user equipment (UE) and an evolved node B (eNB) is described. The UE may communicate with the eNB to establish a small data radio bearer (SDRB), wherein the SDRB is used for communicating the small data from the UE to the eNB. The UE may enter a power saving mode according to a power saving configuration. The UE or the eNB may maintain UE context information for the SDRB while the UE is in the power saving mode. The SDRB may be reestablished using the UE context information when the UE awakes from the power saving mode to enable the UE to communicate the small data on the SDRB to the eNB.

Embodiments of wireless communication devices and method for congestion control in a wireless network are generally described herein. Some of these embodiments describe a method, performed by an evolved NodeB (eNodeB), that includes operations of determining that a congestion condition exists on the network. An example method can also include transmitting a suspension notification to a user equipment (UE), the UE being in an RRC_CONNECTED state with the eNodeB, to notify the UE that a radio bearer (RB) operating in the network will be suspended. Other methods and apparatuses are also described.
摘要:
A communication device is described comprising a message generator configured to generate a message indicating that a mobile terminal is to determine whether a transmitter of the mobile terminal has been active at a predetermined time and provide information which depends on the activity of the transmitter of the mobile terminal at the predetermined time and a transmitter configured to transmit the message.
摘要:
A method to determine a back-off adjustment and transmission power adjustment in a wireless transmit/receive unit (WTRU), the method including determining a problem in signal reception and adjusting a back-off and a transmission power based on a plurality of measurement results.
