Abstract:
An apparatus for notifying of a circuit switched event over a packetized data network. The apparatus includes a packetized data modem and an interworkng interface. The packetized data modem is configured to transmit and receive packetized data over a packetized data radio link. The packetized data modem has a tunneling link access control processor that is configured to encapsulate/decapsulate data for a subset of sub-layers corresponding to a link access control layer of a circuit switched network model. The interworking interface is operatively coupled to the packetized data modem via the packetized data network, and is configured to notify the packetized data modem of the circuit switched event. The interworkng interface has a link access control/tunneling link access control processor that is configured to encapsulate/decapsulate the data when performing notification of the circuit switched event.
Abstract:
System and method for managing connections in a mobile device. A first application may be executing on the mobile device. A first application request, including first quality of service (QOS) parameters and first connection information for the first application, may be received. The first QOS parameters and the first connection information may be stored in a routing table. A first connection for the first application may be established based on the first QOS parameters and the first connection information. A second application may be executing on the mobile device. A second application request, including second QOS parameters and second connection information for the second application, may be received. The second QOS parameters and the second connection information may be stored in the routing table. A second connection for the second application may be established based on the second QOS parameters and the second connection information.
Abstract:
A mobile communication device for application-based class identification is provided with a wireless module and a controller module. The wireless module performs wireless transmissions and receptions to and from a service network. The controller module determines a class of a Machine-to-Machine (M2M) application, and determines a priority level corresponding to the class of the M2M application. Also, the controller module initiates the M2M application via the wireless module according to at least one M2M parameter corresponding to the priority level.
Abstract:
A user equipment for handling an attach procedure with a service network is provided. In the user equipment, a wireless module transmits an attach request message to the service network and receives an attach accept message replied to the attach request message from the service network, while a controller determines whether to accept the attach accept message according to a first parameter accompanying the attach accept message and sends an attach complete message, via the wireless module, to the service network in response to the attach accept message being accepted.
Abstract:
An apparatus supporting MTC in an LTE environment including an LTE modem and a CDMA modem. The LTE modem accesses a first wireless network and executes first data transactions, where the first wireless network comports with LTE standards. The CDMA modem is operationally coupled to the LTE modem, and accesses a second wireless network and executes second data transactions, where the second wireless network comports with one or more CDMA-based standards. The CDMA modem includes an inter-radio access technology (IRAT) API element and an inter-process communication (IPC) module. The IRAT API element is configured to send/receive IRAT messages via function calls to/from the LTE modem, where the IRAT messages remain the same regardless of interface requirements for the LTE modem. The IPC module is coupled to the IRAT API element, and is configured to generalize the function calls to enable the CDMA modem to interoperate with the LTE modem.
Abstract:
A user equipment for handling an attach procedure with a service network is provided. The user equipment comprises a wireless module transmitting an attach request message to the service network and receiving an attach accept message replied to the attach request message from the service network, and a controller determining whether to accept the attach accept message, sending an attach complete message, via the wireless module, to the service network in response to the attach accept message being accepted, and resending the attach request message, via the wireless module, to the service network in response to the attach accept message not being accepted.
Abstract:
A user equipment for alleviating barred access while reselecting from a first cell to a second cell in a mobile communication system is provided. A wireless module detects receives system information broadcasted in the first cell. A storage unit stores the system information. A controller reselects from the first cell to the second cell, determines whether a first barred access timer is running, and stops the first barred access timer and informs the upper layer of an RRC protocol that the access of the first service is allowed in response of that the first barred access timer is running.
Abstract:
A method for reducing signaling overhead in user equipment (UE) connected to a base station is provided. The method includes: when the UE sends Radio Resource Control (RRC) layer messages to the base station, the UE compresses RRC layer messages and sends the compressed RRC layer messages to the base station; and when the UE receives the compressed RRC layer messages from the base station, the UE decompresses the compressed RRC layer messages received from the base station.
