    摘要： System, methods, and networks are disclosed that allow base station systems of a wireless communication network to transmit outgoing traffic over a packet backhaul network to multiple routing elements on the MSC side of the network. A base station system described herein identifies a primary routing element and a backup routing element. The primary routing element is the device to which the base station system transmits outgoing traffic under normal operation, and the backup routing element is an alternate to the primary routing element. To transmit traffic over the packet backhaul network, the base station system monitors the availability of the primary routing element. If the primary routing element is available, then the base station system transmits outgoing traffic over the packet backhaul network to the primary routing element. If unavailable, then the base station system transmits outgoing traffic over the packet backhaul network to the backup routing element.

    摘要： An overload or congestion condition on an access medium (24) of a communication network (22) is indicated by at least one condition that indicates an amount of access attempts on the access medium (24) corresponds to congestion or overload of a capacity of the access medium (24). Example conditions in disclosed embodiments include an occupancy level of the access medium, an average number of access probes associated with successful access attempts, a relationship between received power and interference, an emergency condition and network configuration or maintenance procedures. In a disclosed example, when congestion or overload occurs, at least one technique is implemented to reduce the congestion or overload for stabilizing the access medium. Disclosed example techniques for this include throttling the number of access attempt by reducing the number of users making access attempts or the frequency of user access attempts. Another example technique includes adjusting at least one access medium parameter that will reduce the access attempt traffic.

    摘要： In one embodiment, a reverse link overhead channel power gain for an access terminal is determined based on the service activity of the access terminal. In association therewith, or independent thereof, the reverse link overhead channel power gain may be dynamically adjusted based on the services activated and/or deactivated. The dynamic adjustment may also take into account the load on the system.

    摘要： The present invention is a method and apparatus to aggregate or bundle packets to optimize the resource utilization and improve the transport efficiency of packets which are transferred between various protocol layers in a communications network. One embodiment of the invention sets forth a method of aggregating packets of a first size to packets of a second size for transmission in a wireless communications network between, for example, a base station controller and base transmitting station. The method includes the steps of calculating a maximum bundling factor represented by (an IP packet MTU size at a first location minus protocol overhead) divided by an application layer packet size and determining a most efficient bundling factor in terms of packet fragments, where the most efficient bundling factor is determined by a largest packet per fragment ratio. If the number of packets to be bundled is less than or equal to the maximum bundling factor then all packets are bundled together for a next step in the transmission. If the number of packets to be bundled is greater than the maximum bundling factor, then packets are bundled according to the most efficient bundling factor for the next step in the transmission. If there are multiple bundling factors having a same bundling efficiency, a larger of the multiple bundling factors having the same bundling efficiency is selected as the most efficient bundling factor.

    摘要： A method is provided for controlling the misordering of packets in packet delivery in radio access networks (RANs) and other packet-switched networks. In one aspect, the method involves reading header information to determine the proper sequence of arriving packets, storing at least some packets that have arrived out of order, and forwarding the stored packets in a modified order that has no more than a specified degree of misordering.
