The present invention provides a method involving at least one mobile unit having at least one first session with a base station router. The method includes vacating at least one first session associated with the at least one mobile unit.

Vacating low usage packet data sessions in a wireless communication system

A computer program product for scenario-based source code inspection is provided. The computer program product comprises a computer-usable data carrier storing instructions that, when executed by a computer, cause the computer to display a plurality of functions, the plurality of functions comprising: a first function for creating one or more scenario paths in the source code by providing the ability to create hyperlinks from subroutine/macro calls to the subroutine or macro source in the code and commentary addition; and a second function for inspecting code in execution order and inspecting uninspected lines of code by providing the ability to annotate the code with any errors and observations found and mark lines inspected.

Software tool for scenario-based code inspections

The present invention provides a method involving at least one mobile unit having at least one first session with a base station router. The method includes determining at least one activity level associated with said at least one first session and allocating memory to the at least one first session based on the at least one determined activity level.

Allocating memory to low usage packet data sessions in a wireless communication system

A method, template, protocol, apparatus, system, and computer software for implementing a binary protocol for session initiation in a wireless communications system. The method for creating, modifying or terminating an IP multimedia session among one or more binary session initiation protocol (B-SIP) entities includes providing a flexible template with at least one mandatory field and at least one optional field, wherein the flexible template has fixed and variable length fields, representing a message type with a template id, and maintaining session specific information in a cache. The message template for creating, modifying or terminating an IP multimedia session among one or more binary session initiation protocol (B-SIP) entities, includes at least one mandatory field and at least one optional field, at least one fixed length field and at least one variable length field, wherein each of said at least one variable length fields is preceded by a length field and each of said at least one optional fields is preceded by an identifier, wherein said at least one mandatory field precedes said at least one optional field and said at least one fixed length field precedes said at least one variable length field.

Binary protocol for session initiation in a wireless communications system

In a telecommunications system (), a method and apparatus for buffering the initial speech of an initial speaker in a push-to-talk call is disclosed. The method includes the steps of determining at least one participant or group to call (), sending a call request to the at least one participant or group (), determining if the at least one participant or group is registered with the telecommunications system, notifying the initial speaker to begin speaking after determining at least one participant is registered with the telecommunications system but prior to connecting all called parties, receiving and digitizing voice packets from the initial speaker, storing the digitized data packets in a storage medium and transmitting the digitized voice packets when a predetermined packet transmission triggering event occurs. The apparatus for buffering the initial speech burst of an initial speaker in a call includes a first server () and a second server () communicatively connected to the first server. The second server is programmed to execute the steps of the method described above.

An improved method of updating parameters stored in memory of mobile telecommunications stations. An object model represents all the parameters that can be modified in an IS-683A mobile station. The details of the physical location of each parameter are defined in this mobile object model. Advantageously, when any parameter is changed or added, it is necessary to provide the computer system, which generates messages to be transmitted to the mobile station, only the identification and value of the parameter to be added or changed. The computer system then generates a message sequence that defines the memory location in the mobile station to be changed, and the new value of the data for that memory location. Advantageously, this arrangement sharply reduces the total number of airwave messages transmitted to the mobile station in order to change or add a parameter.
