摘要:
A method for scheduling packets from a plurality of radio bearers by a scheduler of a first layer includes calculating a virtual scheduling time for the radio bearers by using a packet delay variation of the radio bearers, and transmitting the packet of the radio bearer having the greatest virtual scheduling time from among the plurality of radio bearers to a second layer.

Provided is an apparatus and method for setting up a connection of a component carrier (CC) in a mobile communication system of a carrier aggregation (CA) environment. In the mobile communication system operating the CA environment, it is possible to change a CC in an initial connection while maintaining a connection state. When a radio link failure and the like occurs, it is possible to quickly change a disconnected CC using a connected component carrier.

The present invention relates to an apparatus and method for monitoring a battery lifespan of a machine type communication device, and more particularly, to an apparatus and method for preventing a disconnection in communication due to a battery being expended by verifying a battery lifespan of the machine type communication device in a network. The present invention may include detecting a residual capacity of a battery power supply, comparing the residual capacity of the battery power supply to a threshold required for a power supply, and warning against a shortage of the residual capacity of the battery power supply when the residual capacity of the battery power supply is less than or equal to the threshold required for the power supply.

摘要:
The present invention relates to an internet protocol (IP) mobile communication system and a session initiation method thereof. In the IP mobile communication system, a session initiation process using a session initiation protocol is performed for real-time mobile multimedia communication. At this time, not only multimedia codec but also session and quality of service (QoS) information is negotiated from a transmitting terminal to a receiving terminal, and is negotiated between relating network elements. An access manager controls a mobile access router which is a gateway of an access network according to the negotiated session and QoS information. Therefore an additional QoS negotiation process is not necessary for a session guaranteeing the QoS between a terminal and the mobile access router, between the mobile access routers, and between the mobile access router and the receiving terminal.
