Method for controlling a flow of information between secondary agents and a mobile device in a wireless communications system
View Patent ↗In one aspect of the present invention, a method for controlling a communications session with a mobile device is provided. The method comprises selecting a plurality of base stations, where at least a portion of the base stations are adapted to operate as a secondary agent, and wherein the secondary agent is capable of communicating with a mobile device. Substantially similar data is then delivered to a plurality of the secondary agents, and a first one of the secondary agents is selected as a first serving secondary agent to communicate with the mobile device. The first serving secondary agent transfers the data to the mobile device during the communications session.
1. A method for controlling a communications session with a mobile device in a distributed communication system that includes a plurality of base station routers configured to provide wireless connectivity to the mobile device, comprising:
selecting a subset of the plurality of base station routers as primary or secondary agents for the mobile device;
selecting one base station router from the subset of the plurality of base station routers to act as a primary agent for the mobile device and the remainder of the base station routers in the subset to act as secondary agents, wherein the primary agent receives information from a network and controls operation of the secondary agents such that one secondary agent at a time can transmit the received information to the mobile device;
delivering, from the primary agent to each of the secondary agents, substantially similar data representative of the information received from the network;
selecting a first one of the secondary agents as a first serving secondary agent to perform all wireless communications with the mobile device until a second serving secondary agent is selected, the first serving secondary agent transferring the data to the mobile device during the communications session; and
selecting a second one of the secondary agents as the second serving secondary agent to communicate with the mobile device in replacement of the first serving secondary agent, the second serving secondary agent performing all wireless communications with the mobile device until a third serving secondary agent is selected, wherein said wireless communications comprise transferring the data to the mobile device during the communications session.
2. A method, as set forth in claim 1 , wherein:
selecting the second one of the secondary agents as the second serving secondary agent to communicate with the mobile device in replacement of the first serving secondary agent further comprises selecting the second one of the secondary agents as the second serving secondary agent to communicate with the mobile device and transmitting the data to the mobile device at a location within the data substantially corresponding to a location in the data where the first one of the secondary agents ceased transferring data to the mobile device.
3. A method, as set forth in claim 2 , wherein
selecting the second one of the secondary agents as the second serving secondary agent to communicate with the mobile device and transmitting the data to the mobile device at a location within the data substantially corresponding to a location in the data where the first one of the secondary agents ceased transferring data to the mobile device further comprises providing an identification of the location within the data substantially corresponding to a location in the data where the first of the secondary agents ceased transferring data to the mobile device from the first serving secondary agent to the second serving secondary agent.
4. A method, as set forth in claim 1 , wherein:
selecting the first one of the secondary agents as the first serving secondary agent to communicate with the mobile device further comprises selecting the first one of the secondary agents as the first serving secondary agent to communicate with the mobile device based on a characteristic of a communications channel between the first serving secondary agent and the mobile device.
5. A method, as set forth in claim 4 , wherein:
selecting the second one of the secondary agents as the second serving secondary agent to communicate with the mobile device in replacement of the first serving secondary agent further comprises selecting the second one of the secondary agents as the second serving secondary agent to communicate with the mobile device in replacement of the first serving secondary agent in response to a characteristic of a communications channel between the second serving secondary agent and the mobile device being greater than the characteristic of the communications channel between the first serving secondary agent and the mobile device.
6. A method, as set forth in claim 5 , wherein:
selecting the second one of the secondary agents as the second serving secondary agent to communicate with the mobile device in replacement of the first serving secondary agent in response to a characteristic of a communications channel between the second serving secondary agent and the mobile device being greater than the characteristic of the communications channel between the first serving secondary agent and the mobile device further comprises selecting the second one of the secondary agents as the second serving secondary agent to communicate with the mobile device in replacement of the first serving secondary agent in response to a quality of service of a communications channel between the second serving secondary agent and the mobile device being greater than the quality of service of the communications channel between the first serving secondary agent and the mobile device.
7. A method, as set forth in claim 1 , wherein:
selecting the first one of the secondary agents as the first serving secondary agent to communicate with the mobile device further comprises selecting the second one of the secondary agents as the second serving secondary agent to communicate with the mobile device in replacement of the first serving secondary agent in response to loading of the second serving secondary agent.
8. A method, as set forth in claim 1 , further comprising:
periodically delivering new data to the plurality of secondary agents.
9. A method, as set forth in claim 1 , further comprising:
regularly delivering new data to the plurality of secondary agents.
10. A method, as set forth in claim 1 , wherein delivering substantially similar data to a plurality of the secondary agents further comprises streaming data to the plurality of secondary agents.
11. A method, as set forth in claim 1 , wherein delivering substantially similar data to a plurality of the secondary agents further comprises streaming data to the plurality of secondary agents, and wherein selecting the second one of the secondary agents as the second serving secondary agent to communicate with the mobile device in replacement of the first serving secondary agent further comprises discontinuing streaming of data from the first one of the secondary agents at a first setpoint within the data and beginning streaming data to the plurality of secondary agents from a second setpoint within the data, wherein the first and second setpoints substantially coincide.
