Appl. No.:

08/966381

Inventors:

Sang W. Kim - Lawndale CA

Assignee:

International Classification:

G06F 900

US Classification:

709104, 709107

Abstract:

Temporary states are used transitionally in run-time situations and are unknown to the object database. A temporary state is created if, when an object is performing a requested event, interim work needs to be performed before the object reaches a permanent destination state. Use of a temporary state is transparent to the caller of the requested event. Within a single flow of control, an unlimited number of nested locks may be acquired. A request to unlock an object will only truly unlock the object if the unlock requester is at the highest level of locking. For recursive or embedded functions, no knowledge of the previous locking condition is necessary. Attribute-based locking provides a mechanism for allowing only certain members of the system to lock an object for writing while the object is in a predetermined state. However, any thread may obtain a read lock on an object in order to examine its attributes. This may be expanded to state that the system may restrict locking of an object or entity based upon any attribute in the database or upon any combination or logical expression of these attributes.

US Classification:

370252, 370338, 455 69

Abstract:

A method of transmitting channel quality information (CQI) to an access network (AN) in a system having at least one carrier is disclosed. More specifically, the method includes receiving at least one packet from the AN, each of which includes an indicator, wherein the indicator provides buffer level information and ceasing transmission of the CQI of at least one non-anchor carrier to the AN if the buffer level information indicates that there is no more packet to be transmitted to an access terminal (AT).

International Classification:

H04W 4/00

US Classification:

370328

Abstract:

A method of establishing connection between a first mobile station (MS) and a second MS in a mobile communication system is disclosed. More specifically, the method includes transmitting to at least one base station (BS) a service message which includes information of at least one service type supported by the first MS and the second MS. Here the at least one service type relates to a multimedia service supported by each of the first MS and the second MS. Furthermore, the method includes transmitting a request message which includes information of at least one service type selected by the first MS, receiving a response message which includes information of the selected service type which is supported by both the first MS and a second MS, and transmitting a connection complete message between the first MS and the second MS for communication using the selected service type.
