Methods and systems are provided for carrier selection based on probable mobility of packet flow. A request is received from an access terminal. The request comprises a packet-flow-type indication, and indicates that the access terminal is requesting a packet flow. If the packet-flow-type indication is associated with a high degree of mobility, the first access terminal is instructed to conduct the packet flow on one of a first set of one or more carriers. If the packet-flow-type indication is associated with a low degree of mobility, the access terminal is instructed to conduct the packet flow on one of a second set of one or more carriers. No carriers are elements of both the first set and the second set.

A method and system for dynamically varying the number of air interface access channels in a wireless coverage area, based on actual access channel occupancy in the coverage area. A cellular base station monitors actual access channel occupancy in the coverage area. When the base station detects a threshold level of actual access channel occupancy for a threshold time period, the base station automatically changes the number of access channels available for use by mobile stations operating in the coverage area.

Methods and systems are provided for implementing predictive personality negotiation during session negotiation. In an embodiment, an EV-DO access node negotiates a first session with an access terminal, which involves negotiating a comprehensive set of personalities with the access terminal for the first session. The access node then records a list of personalities actually used by the access terminal during the first session. That list is a subset of the comprehensive set. The access node then negotiates a second session with the access terminal, which involves negotiating only that subset of personalities with the access terminal for the second session.

Methods and systems are provided for carrier selection based on type of packet flow. Service is provided to access terminals on a plurality of carriers in a wireless coverage area. A request is received from a first access terminal. The request indicates that the first access terminal is requesting a packet flow, and the request comprises a packet-flow-type indication. It is determined whether the packet-flow-type indication is associated with an expedited-forwarding quality of service (QoS). If the packet-flow-type indication is associated with an expedited-forwarding QoS, it is further determined that, among the plurality of carriers, a first carrier has the fewest ongoing packet flows having the packet-flow-type indication; responsively, the first access terminal is instructed to conduct the requested packet flow on the first carrier.

Methods are provided for implementing selective personality negotiation during session negotiation. In one embodiment, an access node maintains an access-node-supported set of one or more personalities supported by the access node, wherein the access-node-supported set comprises a personality 0. The access node receives from an access terminal an access-terminal-supported set of one or more personalities supported by the access terminal, wherein the access-terminal-supported set also comprises the personality 0. Responsive to receiving the access-terminal-supported set, the access node negotiates a session-specific set of one or more personalities with the access terminal for use by the access terminal during a session, the session-specific set consisting of personality 0 and a first personality, wherein the first personality is a highest-numbered personality in the intersection of the access-node-supported set and the access-terminal-supported set.

Channel elements at a cell site in wireless network are managed by reserving a portion of the channel elements for handling certain types of calls for which the reserved channel elements are capable of handling. At least some of the non-reserved channel elements will typically lack the capabilities of the reserved channel elements, due to there being previous generation or older technology. For example, in a cell cite having both 3G and 2G channel elements, a percentage of the 3G channel elements, such as 15 percent, are reserved for certain types of calls, such as 3G data call origination and 3G voice hand-ins. These are types of calls that the 2G channel elements do not support. The remaining 3G channel elements are not reserved. If the non-reserved channel elements are fully utilized, the reserved channel elements may, or may not, be released for general usage so as to prevent a blocking of calls, depending on quality of service considerations for the site. The reservation of channel elements can be via a configuration parameter issued from a central management entity to base station controllers, on either a system-wide basis, or on a targeted basis to particular base station controllers.
