Abstract
Abstract A method and apparatus for passing network device operations between a source and a target network device which are associated with a mobile communication unit in a radio communication system is provided. This passing of network device operations is accomplished by converting a first form of information to a second form in the source network device. Subsequently, the source and the target network device are notified that operations associated with the mobile communication unit will be passed at a particular time. At that particular time the information converting is bypassed such that the first form of information is provided to the target network device. In addition, the target network device begins to monitor incoming information for the first form of incoming information. In response to a presence of the first form of incoming information at the target network device, the first form of information is converted into the second form in the target network device.

Claims Analysis
Total Claims: 7
Claim 1
Independent Claim
289 words
In a radio communication system having a source and a target transcoder and a mobile communication unit entering a particular communication mode, a method for passing transcoder operations between the source and the target transcoder, the transcoder operations associated with the mobile communication unit, comprising: (a) converting downlink information at the source transcoder from a first type of information to a second type of information; (b) determining a particular time to pass the transcoder operations associated with the mobile communication unit between the source and the target transcoder; (c) notifying the source and the target transcoder of the particular time to pass the transcoder operations; (d) bypassing the downlink information converting step at the source transcoder to provide downlink information of the first type from the source transcoder to the target transcoder, beginning at the particular time; (e) converting uplink information at the target transcoder from the second type of information to the first type of information, beginning at the particular time; (f) at the source transcoder, monitoring uplink information from the target transcoder for a transition to the first type of uplink information, beginning at the particular time; (g) at the source transcoder bypassing the uplink information converting step, in response to detecting the transition to the first type of uplink information, to inhibit conversion of uplink information of the first type from the target transcoder; (h) at the target transcoder, monitoring downlink information from the source transcoder for a transition to the first type of downlink information, beginning at the particular time; and (i) converting the downlink information from the first type to the second type at the target transcoder, in response to detecting the transition to the first type of downlink information at the target transcoder.

In a radio communication system having a source and a target transcoder and a mobile communication unit entering a particular communication mode, a method for passing transcoder operations between the source and the target transcoder, the transcoder operations associated with the mobile communication unit, comprising: (a) converting downlink information at the source transcoder from a first type of information to a second type of information; (b) determining a particular time to pass the transcoder operations associated with the mobile communication unit between the source and the target transcoder; (c) notifying the source and the target transcoder of the particular time to pass the transcoder operations; (d) bypassing the downlink information converting step at the source transcoder to provide downlink information of the first type from the source transcoder to the target transcoder, beginning at the particular time; (e) converting uplink information at the target transcoder from the second type of information to the first type of information, beginning at the particular time; (f) at the source transcoder, monitoring uplink information from the target transcoder for a transition to the first type of uplink information, beginning at the particular time; (g) at the source transcoder bypassing the uplink information converting step, in response to detecting the transition to the first type of uplink information, to inhibit conversion of uplink information of the first type from the target transcoder; (h) at the target transcoder, monitoring downlink information from the source transcoder for a transition to the first type of downlink information, beginning at the particular time; and (i) converting the downlink information from the first type to the second type at the target transcoder, in response to detecting the transition to the first type of downlink information at the target transcoder.
Claim 3
Dependent Claim
36 words
The method of claim 1 wherein the steps of monitoring comprise performing an algorithm selected from the group consisting of: detecting a change in the content of the information and monitoring for a time out event.
Claim 4
Dependent Claim
69 words
The method of claim 1 further comprising the step of establishing a logical connection between the source and the target transcoder by operatively coupling between at least two of the following system entities selected from the group consisting of the source transcoder, the target transcoder, a first base site controller, a second base site controller, a first communication switch, a second communication switch, and a public switched telephone network.
Claim 5
Dependent Claim
17 words
The method of claim 1 wherein the step of passing of transcoder operations occurs across regional entities.
Claim 6
Dependent Claim
64 words
The method of claim 1 further comprising the steps of: (a) passing control information to the target transcoder indicating that the target transcoder is to take over communications with the mobile communication unit; and (b) releasing the source transcoder from communication with the mobile communication unit, in response to the target transcoder receiving control information to take over communications with the mobile communication unit.
Claim 7
Dependent Claim
65 words
The method of claim 1 further comprising the steps of: (a) passing control information to the source transcoder indicating that the source transcoder is to maintain communications with the mobile communication unit; (b) leaving the target transcoder in an original state of communications with the mobile communication unit, in response to the source transcoder receiving control information to maintain communications with the mobile communication unit.
