Network access management
Within a satellite communications system, a base station communicates with standard compliant user equipment (UE) via a satellite having a field of view. The base station has a processor that instructs the satellite to generate a wide beam signal covering a plurality of cells in the field of view, and detects an access request from a user equipment within the plurality of cells over the wide beam signal. The base station, comprising a processing device such as an eNodeB, then generates one or more network broadcast/access signals that is uplink to a satellite and broadcasted via one or more nominal beams generated by the satellite, covering all the inactive cells, one of the plurality of cells having the access request.
1. A satellite communications system comprising:
a base station configured to communicate with standard compliant user equipment (UE) via a satellite having a field of view, said base station comprising:
a processing device configured to communicate, via the satellite, a broadcast signal over a wide beam signal covering a plurality of cells in the field of view, detect an access request from an active user equipment within the plurality of cells over the wide beam signal, and communicate, via the satellite in response to the detected access request, a broadcast signal over one or more nominal beam signals each covering one of the plurality of cells;
the processing device being further configured to determine which one of the one or more nominal beam signals communicates with the active user equipment, establish via one of the one or more nominal beam signals a connection with the active user equipment over a new nominal beam signal to conduct communications with the active user equipment, and turn off the one or more nominal beam signals that do not communicate with the active user equipment.
2. The satellite system of claim 1 , wherein said processing device is configured to maintain a list of active user equipment connections and include the established connection in the list of active user equipment connections.
3. The satellite system of claim 1 , said processing device further configured to detect a plurality of access requests and generate new respective nominal beam signals for each one of the plurality of cells having at least one of the plurality of access requests.
4. The satellite system of claim 1 , wherein said user equipment comprises standard cellular phones.
5. The satellite system of claim 1 , wherein the plurality of cells include an active cell having one or more connected UE and an inactive cell having no connected UEs, said processing device configured to generate an active nominal beam signal covering each active cell and turn off the one or more nominal beams at the inactive cells.
6. The satellite system of claim 1 , wherein the wide beam signal has a different frequency than the one or more nominal beam signals.
7. A base station configured to communicate with standard compliant user equipment (UE) via a satellite having a field of view, said base station comprising a processing device configured to generate, via the satellite, a broadcast signal over a wide beam signal covering a plurality of cells in the field of view, detect an access request from an active user equipment within the plurality of cells over the wide beam signal, and generate, in response to the detected access request, a broadcast signal over one or more nominal beam signals each covering one of the plurality of cells;
wherein the processing device is further configured to determine which one of the one or more nominal beam signals communicates with the active user equipment, establish via one of the one or more nominal beam signals a connection with the active user equipment to conduct communications with the user equipment, and turn off the one or more nominal beam signals that do not communicate with the active user equipment.
8. The base station of claim 7 , wherein said processing device is configured to maintain a list of active user equipment connections and include the established connection in the list of active user equipment connections.
9. The base station of claim 7 , said processing device further configured to detect a plurality of access requests and generate respective nominal beam signals for each one of the plurality of cells having at least one of the plurality of access requests.
10. The base station of claim 7 , wherein said user equipment comprises standard cellular phones.
11. The base station of claim 7 , wherein the plurality of cells include an active cell having one or more connected UE and an inactive cell having no connected UEs, said processing device configured to generate an active nominal beam signal covering each active cell and turn off the one or more nominal beams at the inactive cells.
