Method and apparatus for concurrently processing multiple calls in a spread spectrum communications system
First Claim
1. An apparatus for processing calls concurrently, comprising:
- a controller to receive an indication of a first call to be processed, the controller to determine a first service option connection to be mapped to the first call and to instantiate a first call control state machine of a type in accordance with a type of the first call, the first call control state machine being used to control processing of the first call, and the controller to establish a set of one or more physical channels associated with the first service option connection to be used for data transmission.

Abstract
The call processing state machines defined by the CDMA standards (e.g., IS-95 and IS-2000) are modified to include a “traffic channel” substate indicative of the mobile station processing at least one active call. Call control (CC) state machines of various types are also provided to control the processing of the calls. To process one or more calls concurrently, a CC state machine is instantiated upon receiving an indication to process a particular call. The instantiated CC state machine is identified with, and used to control the processing of, the particular call. Upon receiving an indication to process an additional call, another CC state machine can be instantiated for the additional call. Each call to be processed can also be associated with a particular a service option connection, which includes information indicative of a set of parameters (e.g., the physical channels) to be used for data transmission.

6. An apparatus for processing calls, comprising:
a control processor to implement a call processing state machine including a first state indicative of a period of synchronization with a particular communication system, a second state indicative of a period of monitoring of a paging channel, a third state indicative of a period of accessing a base station in the particular communication system, and a fourth state indicative of processing of at least one active call, each active call being associated with a call control state machine. - View Dependent Claims (7, 8, 9)
