Apparatus, system, and method for access procedure enhancements
View Patent ↗A service network for access procedure enhancement includes a radio access network performing wireless transmissions and receptions to and from a mobile communication device. The service network also includes a control node receiving an access probe from the mobile communication device via the radio access network, determining whether the access probe indicates that a length of message data is less than a threshold, and transmitting a pre-acknowledgement of the access probe to the mobile communication device via the radio access network in response to the length of the message data being less than the threshold.
1. A service network for access procedure enhancement, comprising:
a radio access network configured to perform wireless transmissions and receptions to and from a mobile communication device; and
a control node configured to:
receive a first access probe comprising a data length corresponding to a length of a message data from the mobile communication device via the radio access network,
determine whether the first access probe is decodable in response to detecting a preamble in the first access probe;
transmit a first pre-acknowledgement of the first access probe to the mobile communication device via the radio access network in response to determining that the length of the message data is less than a threshold and based on the determined decodability of the first access probe, and
after transmitting the first pre-acknowledgement of the first access probe, receive a second access probe comprising the message data from the mobile communication device via the radio access network, the message data replacing the data length of the message data to generate the second access probe received from the mobile communication device,
wherein the control node is further configured to broadcast a second pre-acknowledgement with information of the first access probe via the radio access network in response to determining that the first access probe is non-decodable.
2. The service network of claim 1 , wherein the control node is further configured to:
transmit an acknowledgement of the second access probe to the mobile communication device via the radio access network.
3. The service network of claim 1 , wherein the control node is further configured to broadcast information concerning reverse-link load information of the service network to the mobile communication device via the radio access network.
4. The service network of claim 3 , wherein the reverse-link load information comprises:
a reverse-link load level;
a minimum server quality or a minimum transmission power headroom; and/or
a reverse-link open-loop adjust value for open-loop power control.
5. The service network of claim 1 , wherein a transmission power associated with the second access probe is determined based on a transmission power associated with the first access probe.
6. The service network of claim 5 , wherein the transmission power associated with the second access probe is further determined based on the first pre-acknowledgement of the first access probe.
7. The service network of claim 5 , wherein the transmission power associated with the second access probe is the same as the transmission power associated with the first access probe.
8. The service network of claim 1 , wherein a transmission power associated with the second access probe is determined based on a transmission power associated with the first access probe and the first pre-acknowledgement of the first access probe, the transmission power associated with the second access probe being the same as the transmission power associated with the first access probe.
9. A method for access procedure enhancement by a service network comprising a radio access network, comprising:
receiving a first access probe comprising a data length corresponding to a length of a message data from a mobile communication device via the radio access network;
determining whether the first access probe is decodable in response to detecting a preamble in the first access probe;
determining whether the first access probe indicates that the length of message data is less than a threshold;
transmitting a first pre-acknowledgement of the first access probe to the mobile communication device via the radio access network in response to the length of the message data being less than the threshold and based on the determined decodability of the first access probe;
after transmitting the first pre-acknowledgement of the first access probe, receiving a second access probe with the message data from the mobile communication device via the radio access network, the message data replacing the data length of the message data to generate the second access probe received from the mobile communication device; and
broadcasting a second pre-acknowledgement with information of the first access probe via the radio access network in response to determining that the first access probe is non-decodable.
10. The method of claim 9 , further comprising:
transmitting an acknowledgement of the second access probe to the mobile communication device via the radio access network.
11. The method of claim 9 , further comprising broadcasting information concerning reverse-link load information of the service network to the mobile communication device.
12. The method of claim 11 , wherein the reverse-link load information comprises:
a reverse-link load level;
a minimum server quality or a minimum transmission power headroom; and/or
a reverse-link open-loop adjust value for open-loop power control.
