Abstract

A wireless communications network (100) comprising a plurality of sites (102-114) each of which is served by a node (116-128), and said nodes (116-128) are connected with other elements of the network infrastructure. The network further comprises a plurality of mobile stations (130-134). At least one of said sites (102) has a first control channel and the remaining sites (104-114) do not have control channels, wherein said infrastructure is adapted, using said first control channel, to direct a mobile station (130-134) located in a site without a control channel (104-114) to a traffic channel.

Claims

1. A wireless communications network (100) comprising a plurality of sites (102-114) each of which is served by a node (116-128), and said nodes (116-128) are connected with other elements of the network infrastructure, and further comprising a plurality of mobile stations (130, 134), characterized in that at least one of said sites (102) has a first control channel (140) and the remaining sites (104-114) do not have control channels, wherein said infrastructure is adapted, using said first control channel (140), to direct a mobile station (130) located in a site without a control channel (114) to a traffic channel depending on a geographical location of said mobile station (130).

2. The network (100) according to claim 1, wherein said infrastructure is further adapted, using said first control channel (140), to direct a mobile station (134) located in said site (102) with said first control channel (140) to a traffic channel.

3. The network (100) according to claim 1, wherein said geographical location of said mobile station (130, 134) is obtained from a separate radio data channel.

4. The network (100) according to claim 3, wherein said separate radio data channel is a Global Positioning System/GPS/channel (144).

5. The network (100) according to claim 1, wherein said infrastructure is adapted to obtain a geographical location of said mobile station by analyzing signals received from said mobile station (130, 134).

6. The network (100) according to claim 5, wherein said infrastructure is adapted to use an angle of arrival or RSSI or triangulation or any combination thereof to obtain geographical location of said mobile station (130, 134).

7. The network (100) according to claim 1 and which is operable according to TETRA or ASTRO/APCO-25 standards.

8. The network (100) according to claim 1, wherein said sites without control channels (104-114) form a high speed data overlay on the at least one site (102) with a control channel.

9. The network (100) according to claim 1, wherein said nodes (116-128) are adapted to increase a bit rate of traffic channels by reducing energy-per-bit factor.

10. A method of assigning a mobile station to a traffic channel in a wireless communications network, said network comprising a plurality of sites (102-114) each of which is served by a node (116-128), and said nodes (116-128) are connected with other elements of the network infrastructure, and further comprising a plurality of mobile stations (130, 134), wherein at least one of said sites (102) has a first control channel (140) and the remaining sites (104-114) do not have control channels, wherein said infrastructure, using said first control channel (140), directs (212) a mobile station located in a site without a control channel to a traffic channel depending on a geographical location (204-210) of said mobile station.
