摘要： A method and system to assign a contention-free access resource 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 involves the first network detecting an attempt to set up a circuit-switched-fallback (CSFB) call between (i) a UE served by the first network and (ii) a remote party, where the CSFB call is to be served by the second network to which the UE would transition to be served with the CSFB call. The method further involves, in response to detecting the attempt to set up the CSFB call, the first network assigning a contention-free access resource to the UE, so as to allow a contention-free access request by the UE to the first network.

摘要： During the operation of a radio access network (RAN), the RAN will determine a measure of capacity of a frequency channel based on a modulation quality (Rho) of the frequency channel and will intelligently manage use of the frequency channel based on the determined Rho. Through this process, the RAN may thereby attempt to serve each WCD with an appropriate level of service by reducing a maximum load level for the frequency channel. In response to a WCD attempting to register on a frequency channel, the RAN may determine if registering the WCD would cause a current load level to exceed the maximum load level of the frequency channel. If registering would cause a current load level of the frequency channel to exceed the maximum load level, the RAN may cause the WCD to register on a different frequency channel. If not, the RAN may allow the registration.

摘要： A method of managing modulation for transmission of data in anticipation of handover. When a source base station is serving a UE and determines that the UE is going to hand over to a target base station, the source base station automatically transitions to transmit data to the UE with a low-order MCS selected without regard to CQIs reported by the UE, or at least to apply an MCS corresponding with a CQI lower than that reported by the UE. By applying a low-order MCS to transmit data to the UE, the source base station may increase the likelihood that the data will arrive successfully at the UE, as the low-order MCS may be more tolerant to noise than higher-order MCSs.

摘要： A method and system is disclosed for coordinating codec consistency based on cross-carrier assignments. When a new voice call (or other communication session) is set up between access terminals in a wireless communication system, a network device, such a base station, can determine a respective maximum coding rate supported on carrier frequencies of both an originating access terminal and a terminating access terminal. The network device can then select a coding rate that best accommodates the respective maximum coding rates. Each access terminal may then be instructed to use the selected coding rate for the new call (or communication session). Either or both access terminals may also execute a frequency handoff to a carrier frequency that supports the selected coding rate, if necessary.

摘要： Quality of Service (QoS) priority values and thresholds are defined for various service types assignable to user equipment (UE devices) including multiple bandclass devices. The QoS thresholds can be used for determining whether resources of a default or alternate bandclass should be used for a new call request or whether a timer should be initiated to wait for additional resources to become available. A default QoS priority values can be assigned to each service type and used for voice calls requested by UE devices. QoS priority values with lower priority can be used for data calls. The priority of priority values can decrease as the data rate for the data calls increases. Thresholds for blocking call requests can be increased or decreased to improve likelihood that resources for call requests with higher priority service types are granted at the expense granting resources for call requests with lower priority service types.

摘要： Systems and methods for allocating frequencies based on group delay variation considerations include a base station that operates in a frequency range comprising a first set of frequency groups and a second set of frequency groups, where frequency groups of the first set are less susceptible to group delay variation based impairments than the frequency groups of the second set. In response to a requirement to transmit data between the base station and a particular UE, the base station determines whether the particular UE is receiving wireless service directly from the base station or via a relay associated with the base station, and when the particular UE is receiving wireless service via the relay, the base station allocates one or more frequency groups from the first set of frequency groups to use for transmitting data between the base station and the particular UE to satisfy the requirement.

摘要： A method and system for dynamically selecting call setup procedure based on channel quality. While a wireless communication device (WCD) is being served by a first radio access network (RAN), a network node receives an indication of a communication quality of the at least one channel used by the first RAN to serve the given WCD. Then, the network node selects a call setup procedure for establishing a call to be served by a second RAN based on the received indication of the communication quality of the at least one channel, where the selected call setup procedure comprises the given WCD transitioning to be served with the call by the second RAN. Next, the network node signals to invoke setup of the call using the selected call setup procedure.

摘要： Disclosed is a method and system for channel selection. As disclosed, a wireless communication system includes a base station that is configured to operate on a plurality of channels, each having a respective level of port-to-port isolation. The system determines a measure of quality of an air interface between the base station and a user equipment device (UE) served by the base station. The system then selects, from the plurality of channels, a channel on which the base station should serve the UE, where the selecting is based at least in part on (i) the determined measure of quality of the air interface between the base station and the UE and (ii) a correlation between the determined measure of quality of the air interface and the respective level of port-to-port isolation of the channel. Upon the selection, the base station serves the UE on the selected channel.

摘要： Disclosed herein are systems and methods for symmetrical implementation of inter-cell interference coordination (ICIC) in a radio access network (RAN) having a first base station serving a first set of access terminals and a second base station serving a second set of access terminals. In an embodiment, a network entity makes both a first determination that each access terminal in the first set is receiving at least a threshold-strong signal from the second base station and a second determination that each access terminal in the second set is receiving at least a threshold-strong signal from the first base station. Responsive to making these determinations in combination, the network entity manages an assignment of reverse-link resource blocks in the RAN such that no reverse-link resource blocks are assigned to both an access terminal in the first set and an access terminal in the second set.
