Abstract: A request to establish a call involving a wireless communication device (WCD) served by a radio access network (RAN) may be received. The WCD may receive signals from the RAN via a plurality of wireless coverage areas at respective signal strengths. The plurality of wireless coverage areas may be defined by the RAN. A media codec to use for the call and a target bitrate for the media codec to use during the call may be determined. Based on the target bitrate, a set of n wireless coverage areas through which the WCD and the RAN communicate during the call may be selected. The value of n may be between one and a predetermined maximum number. The set of n wireless coverage areas may be selected from the plurality of wireless coverage areas.

Abstract: A radio access network (RAN) may receive a call setup request from a wireless communication device (WCD). The call setup request may indicate that the WCD supports a first media codec. The RAN may obtain a set of candidate wireless coverage areas for serving the WCD. A first subset of the candidate wireless coverage areas may support the first media codec, and a second subset of the candidate wireless coverage areas might not support the first media codec. The RAN may assign traffic channels to the WCD, such that the assigned traffic channels include traffic channels from at least two of the first subset of the candidate wireless coverage areas, but do not include traffic channels from any of the second subset of the candidate wireless coverage areas. The RAN may communicate with the WCD substantially simultaneously via the assigned traffic channels using the first media codec.

Abstract: A RAN may determine a metric indicative of a prevalence of WCDs of a first type served by the RAN. WCDs of a second type may also be served by the RAN. WCDs of the first type may communicate with the RAN using a first air-interface or a second air-interface, and WCDs of the second type may communicate using the second air-interface. The RAN may engage in a first extent of communication with WCDs of the first type or the second type when using the second air-interface. The RAN may compare the metric to a threshold WCD prevalence, and based on the comparison, select a second extent of communication to engage in with WCDs of the first type or the second type. The RAN may receive a call setup request related to a particular WCD, and select at most the second extent of wireless coverage areas for the particular WCD.

Abstract: A method and system is disclosed for coordinating codec assignment and radio configuration in wireless communication sessions. When a communication session is set up for an access terminal (AT) operating in a wireless communication system, a network device, such a base station, can determine a coding rate to assign the AT for its air interface in a manner that accounts for radio configuration in a wireless coverage zone of the base station. The base station could use a distribution of types of cover codes in use to monitor radio configuration, and then assign a codec and coding rate for new calls based on the distribution.

Abstract: A method and system is disclosed for maintaining codec consistency across a communication session. When a communication session is set up for an access terminal (AT) operating in a wireless communication system, a network device, such a base station, can determine a coding rate to assign the AT for its air interface in a manner that accounts for network capacity variations across the session. If the AT is predicted to handoff to multiple sectors during the session, then a coding rate that best accommodates the air interfaces of all the predicted handoff sectors, but that does not result in consistently low coding rates for the AT, may be used.

Abstract: A method and apparatus for handing off packet-transmission between sectors of a wireless communication system is disclosed herein. During transmission of a packet from an access network to an access terminal, the access terminal determines that the packet should theoretically be transmitted to the access terminal in fewer timeslots in another sector than the number of allowed timeslots remaining for the packet transmission in a current sector. In response, the access terminal abandons packet transmission in the current sector and hands off to the other sector, in an effort to increase throughput and save air interface resources.

Abstract: When a donor base station serves a relay on a wireless backhaul connection that encompasses at least two carriers, and where the relay includes a relay base station and a relay-WCD, communications over the wireless backhaul connection will be distributed among the carriers based on whether the communications are control-plane communications with the relay base station or rather user-plane communications with a WCD served by the relay base station. For instance, all such control-plane communication could be carried on one of the carriers, and all such user-plane communication could be carried instead on another of the carriers.

Abstract: A base station that provides coverage on at least one TDD carrier and at least one FDD carrier detects that the base station is serving a UE on just one or more of the TDD carrier(s) and that the UE is TDD-FDD CA capable. In response, the base station reconfigures the UE to change the UE's carrier prioritization from (i) prioritizing TDD over FDD to (ii) prioritizing FDD over TDD. For instance, if TDD carriers are defined in one or more frequency bands, and FDD carriers are defined in one or more other frequency bands, this could involve changing the UE's band prioritization to cause the UE to prefer connecting on TDD.

Abstract: A radio access network (RAN) may receive a request to establish a call involving a wireless communication device (WCD) served by the RAN. The WCD may receive signals from the RAN, via a plurality of wireless coverage areas, at respective signal strengths. A set of n wireless coverage areas may be selected from the plurality of wireless coverage areas to support communications related to the call, where n is at least 2. A service option to use for the call may be determined, where the service option indicates a call type. Based on the indicated call type, at least one wireless coverage area may be removed from the set of n wireless coverage areas. The call may be established between the RAN and the WCD.

Abstract: A method and system to help manage resources in a fallback scenario is disclosed. A first network may be configured to serve user equipment devices (UEs) according to a first protocol and a second network may be configured to serve UEs according to a second protocol. The method may involve the first network serving a UE, where serving the UE includes allocating at least one resource to the UE. The method may also involve, after the UE has transitioned from being served by the first network to being served by the second network for a circuit-switched-fallback call, (i) if the UE completes call setup, the first network releasing the resources, but (ii) if the UE does not complete call setup, the first network using the allocated resources to serve the UE after the UE transitions back to being served by the first network.
