The claims below are in addition to those above.
All refrences to claim(s) which appear below refer to the numbering after this setence.
1. A communications management method for a random access communications network, in which time intervals are broken down into access slots, and during an access slot, a network terminal transmits an access request to the random access communications network associated with a message to be transmitted by the network terminal, and said random access communications network comprises at least one processing device that causes a time required for transmission of an access request acknowledgement message acknowledging the access request to said network terminal to exceed a duration of the given access slot, the method comprising:
periodically sending an acknowledgement message to said network terminal, said acknowledgement message comprising positive acknowledgement information associated with said access slot, wherein if the acknowledgement message acknowledging the access request is received during the access slot in which the access request was transmitted, the network terminal transmits the message associated with said access request.
2. The method according to claim 1, wherein if said random access communications network detects a collision of access requests, messages associated with said access requests are not handled.
3. The method according to claim 1, wherein if said random access communications network detects a collision of access requests, auxiliary acknowledgement messages addressed to level 2 and 3 protocol layers are not transmitted to the network terminals associated with said collision.
4. The method according to claim 3, wherein if the network terminal has transmitted a message after reception of the acknowledgement message, the network terminal resends said access request if the network terminal has not received an auxiliary acknowledgement message from the network.
5. The method according to claim 1, wherein if the network terminal needs to transmit a message and said random access communications network has detected a collision of access requests, said network terminal resends said access request at a variable time interval.
6. The method according to claim 5, wherein said variable time interval varies at random.
7. The method according to claim 5, wherein said variable time interval varies within an interval between one tenth of a millisecond and a few tens of a millisecond.
8. The method according to claim 1, wherein if the random access communications network has acknowledged a first access request transmitted by a network terminal, a dedicated two-directional channel is assigned to said network terminal, and the contents of a measurement report message having measurements made by the said network terminal on at least one of said dedicated channel in the random access communications network to terminal direction (forward channel) and the signal quality received by the random access communications network on the dedicated channel are analyzed, and
wherein the random access communications network sending power is modified as a function of the contents of said measurement report message.
9. The method according to claim 8, wherein the random access communications network sends a message to reconfigure said measurement report message on said dedicated channel.
10. The method according to claim 1, wherein if the random access communications network has acknowledged a first access request transmitted by a network terminal, a two-directional channel is dedicated to said network terminal, signal quality received on said two-directional channel is analyzed to adapt the configuration parameters of the dedicated channel as a function of the quality of the signal quality analysis, and if said two-directional channel is adapted based on said signal quality analysis, the random access communications network sends one or more reconfiguration messages on said dedicated channel containing the adapted configuration parameters, and said network terminal modifies the configuration of said two-directional channel in the network terminal to random access communications network direction.
11. The method according to claim 10, wherein said two-directional channel is adapted based on the sending power of said network terminal.
12. The method according to claim 10, wherein if the network terminal modifies the configuration of said two-directional channel in the network terminal to random access communications network direction, said network terminal sends a message confirming execution of the said modification to the random access communications network.
13. An equipment for management of access requests to a random access communications network in which time intervals are broken down into access slots, and during an access slot a network terminal transmits an access request to the random access communications network associated with a message to be transmitted by said network terminal, and said random access communications network comprises at least one processing device that causes a time for transmission of an access request acknowledgement message acknowledging said access request to said network terminal to exceed a duration of a given access slot in which the access request was transmitted, wherein said equipment executes the method according to claim 1.
14. The method according to claim 1, wherein the acknowledgment messages are periodically sent from the random access communications network to said network terminal.
15. The method according to claim 1, wherein the access request is an initial request having a preamble, by the network terminal to the random access communications network, to transmit the associated message over the random access communications network.
16. The method according to claim 1, wherein the random access communications network comprises at least one of a 3G satellite communications network, a W-CDMA network, a CDMA 200 satellite network, a TTA network, a CCSA network, an S-UMTS network, and an S-CSMGPRS network.
