A method is provided for dynamically allocating capacity to uplinks and downlinks in a communication network. In the method, base stations of the communication network are apportioned into groups. Each of the base stations communicates over an uplink and a downlink with communication devices. For each of the groups, a first indication of utilization of the uplink for each of the base stations of the group is received. Also received is a second indication of utilization of the downlink for each of the base stations of the group. A capacity allocation between the uplinks and the downlinks of the base stations of the group is determined based upon the first and second indications. The capacity allocation is then employed for each of the base stations of the group.

A mobile communication device wirelessly transfers user communications to a first wireless base station. The mobile communication device identifies a second wireless base station that has sufficient performance characteristics for wireless communication with the mobile communication device and that has a higher communication priority than the first wireless base station. In response, the mobile communication device initiates a hand-off from the first wireless base station to the second wireless base station. In response to the hand-off, the mobile communication device stops the wireless transfer of the user communications to the first wireless base station and wirelessly transfers additional user communications to the second wireless base station.

Methods and systems for assigning time-division multiplexed (TDM) slots in a multi-channel TDM system are presented. Preferably, a radio access network (RAN) assigns forward link and reverse link transmissions between the RAN and one or more wireless communication devices (WCDs) to TDM slots on various wireless channels. When making these assignments, the RAN may take into account (i) the priority of data that the RAN queues for the WCDs, and (ii) the signal quality at which the WCDs can receive the various wireless channels.

A method is disclosed that can be carried out in an access network comprising a plurality of coverage areas, each coverage area being served by an RNC. The method involves making a determination that an access terminal is located in an inter-RNC boundary zone, and then, during a communication session: (i) determining that a handoff from a source coverage area to a target coverage area should be performed; (ii) determining whether or not the target coverage area is served by the same RNC as the source coverage area; (iii) if the target coverage area is not served by the same RNC as the source coverage area, delaying handoff until a current segment of the communication session is complete; and (iv) if the target coverage area is served by the same RNC, handing off the communication session to the target coverage area.

A method of operating a communication system is disclosed. The method includes exchanging a first communications between an access node and an antenna node over a first link and processing the first communications to determine a first delay metric, wherein the first delay metric indicates a first time delay associated with the first link. The method also includes exchanging a second communications between the access node and a wireless communication device over a third link, wherein the third link comprises the first link and a second link between the antenna node and the wireless communication device and processing the second communications to determine a second delay metric, wherein the second delay metric indicates a second time delay associated with the third link. The method also includes processing the first delay metric and the second delay metric to determine a third delay metric and timing a third communications between the access node and the wireless communication device over the third link based on the third delay metric.

A system to control paging cycles in a wireless network assigns mobile stations to one of a plurality of paging groups based on the paging cycle requirements of the individual mobile stations. In addition, the mobile stations in a particular paging group are further subdivided into subgroups that may be substantially equal in size. At any particular paging cycle, only one subgroup of a particular paging group is included in the paging process thus reducing the overall number of mobile stations that need to be paged in any particular paging cycle.

Systems and methods of operating multimode 3G/4G communications devices in an overlapping 3G/4G coverage area (e.g., WiMAX or LTE/CDMA-EvDO) include determining a loading condition of the 3G and 4G base stations. If the 3G and 4G base stations are lightly loaded, one or more 4G Channel Quality Indicators (CQI) are compared with one or more corresponding 3G Data Rate Control (DRC) indices to determine which of the 3G and 4G networks allows a higher data throughput. The dual mode communications device is handed off to a 4G base station associated with the 4G coverage if the 4G network allows the higher data throughput; otherwise, the dual mode communications device is handed off to a 3G base station. User priorities, application categories, and/or MIMO and diversity modes may be used to determine handoff if the base stations are more than lightly loaded.

An inspection node receives an event to begin monitoring a traffic flow where the event comprises a flow identifier associated with the traffic flow. The inspection node receives the traffic flow where the traffic flow comprises a plurality of packets and begins inspecting the plurality of the packets to obtain an application identifier. Based upon the flow identifier and the application identifier, the inspection node performs a sampling process on the traffic flow. After determining the end of the traffic flow, the inspection node terminates the sampling process.
