System and method for dynamic allocation of capacity on wireless networks
A wireless communication system is described for allocating limited network access according to priorities designated for requested transactions of wireless communications. The wireless network has a number of access links for transmitting transactions for wireless communications. A plurality of wireless communications devices requests transmission of transactions on the wireless network. A designated priority level is associated with each transaction. In response to the transaction requests, an access control manager in the wireless network schedules transmission of transactions when all of the plurality of access links are occupied, by authorizing a transmission of a transaction of higher priority than another transaction that is being transmitted, and discontinuing the transmission of the transaction of lower priority.
1. A wireless communications device comprising:
a communications manager; and
a memory storing an application and instructions that, when executed by the communications manager, cause the communications manager to perform operations comprising
receiving, from the application, a transaction request for a transaction, the transaction associated with a first priority level, wherein the first priority level effects a quality of service across a wireless network and a wired network,
generating a control packet to request transmission of the transaction, the control packet comprising the first priority level for the transaction and at least one of a desired data rate for transmission of the transaction, information indicating whether transmission of the transaction is a symmetric transmission or an asymmetric transmission, information indicating whether transmission of the transaction is associated with an encryption on or an encryption off, an acceptable delay for transmission of the transaction, an estimated quantity of data for transmission of the transaction, an expected duration for transmission of the transaction, or a destination point of session for transmission of the transaction,
causing the control packet to be transmitted to the wireless network to request transmission of the transaction,
in response to a denial of access from the wireless network denying transmission of the transaction, waiting to receive a broadcast message from the wireless network describing a current capacity of the wireless network before retransmitting the control packet to request transmission of the transaction, and
after transmission of a portion of data of the transaction via the wireless network, reconfiguring the control packet associated with the transaction to associate a remaining portion of the data of the transaction with a second priority level that is higher than the first priority level associated with the portion of the data of the transaction transmitted via the wireless network.
2. The wireless communications device of claim 1 , further comprising a queue that stores the data of the transaction to be transmitted.
3. The wireless communications device of claim 2 , wherein the transaction is scheduled within the queue based on the first priority level.
4. The wireless communications device of claim 1 , wherein the application is configured to operate at a plurality of priority levels.
5. The wireless communications device of claim 1 , wherein the communications manager is further for receiving, from an access control manager of the wireless network, the broadcast message, wherein the broadcast message comprises a warning message that access to the wireless network at the first priority level is unavailable.
6. A method comprising:
receiving, by a communications manager of a wireless communications device, from an application of the wireless communications device, a transaction request for a transaction, the transaction associated with a first priority level, wherein the first priority level effects a quality of service across a wireless network and a wired network;
generating, by the communications manager of the wireless communications device, a control packet to request transmission of the transaction, the control packet comprising the first priority level for the transaction and at least one of a desired data rate for transmission of the transaction, information indicating whether transmission of the transaction is a symmetric transmission or an asymmetric transmission, information indicating whether transmission of the transaction is associated with an encryption on or an encryption off, an acceptable delay for transmission of the transaction, an estimated quantity of data for transmission of the transaction, an expected duration for transmission of the transaction, or a destination point of session for transmission of the transaction;
causing, by the communications manager, the control packet to be transmitted to the wireless network to request transmission of the transaction;
in response to a denial of access from the wireless network denying transmission of the transaction, waiting to receive a broadcast message from the wireless network describing a current capacity of the wireless network before retransmitting the control packet to request transmission of the transaction; and
after transmission of a portion of data of the transaction via the wireless network, reconfiguring, by the communications manager, the control packet associated with the transaction to associate a remaining portion of the data of the transaction with a second priority level that is higher than the first priority level associated with the portion of the data of the transaction transmitted via the wireless network.
7. The method of claim 6 , further comprising a queue that stores the data of the transaction to be transmitted.
8. The method of claim 7 , wherein the transaction is scheduled within the queue based on the first priority level.
9. The method of claim 6 , wherein the application is configured to operate at a plurality of priority levels.
10. The method of claim 6 , further comprising receiving, from an access control manager of the wireless network, the broadcast message, wherein the broadcast message comprises a warning message that access to the wireless network at the first priority level is unavailable.
