Abstract: PURPOSE: A method for allocating a physical uplink shared channel on a VoIP service is provided to prevent the waste of resource caused by unnecessary resource allocation by judging the resource allocation. CONSTITUTION: A base station receives from an MS(Mobile Station) a resource allocation request for uplink data transmission(S520), and recognizes an LCG(Logical Channel Group) identifier of a buffer state report within the resource allocation request(S530). If VoIP(Voice over Internet Protocol) uplink scheduling request buffer size is equal to or larger than the amount of transmission data of preset VoIP service, the base station allocates a PUSCH(Physical Uplink Shared Channel) to the terminal(S540,S550).

Abstract: A system for supporting the multiple interfaces of a terminal in a single packet data network is provided to enable the terminal to use the same IP address even when using any interfaces in the single packet data network, thereby minimizing a delayed time caused by handover when the terminal performs handover through a changed interface and preventing a loss of data during the handover. A system for supporting the multiple interfaces of a terminal in a single packet data network comprises a user terminal(200), a wireless access system(250,255), and a wireless access gateway(210). The user terminal has multiple interfaces. The wireless access system provides a wireless access connection to the user terminal. The wireless access gateway provides multiple binding to the user terminal so that different interfaces use the same IP(Internet Protocol) address when the user terminal is connected to the single packet data network through the multiple interfaces.

Abstract: A system for dynamically combining services based on user context and a service providing method thereof are provided to dynamically combine/offer a new service as well as the service registered from a user by considering user information, the user context, and service use records collected from a physical region in a ubiquitous environment. A physical region part(240) detects the context including customer information, preference, an environment state, a physical state, and a service state of a customer. A context recognizer(230) recognizes the context of the customer based on the context detected from the physical region part and stores/manages the recognized context. A service provider(220) provides the service adapted to the customer by estimating and combining the services based on the context and the service use records. An application part(210) is connected to the customer and an SP(Service Provider), and transfers customer request information and service provision information for providing the service.
