Abstract:
At least one embodiment of the invention is directed to communicating in a wireless communications system, including monitoring a communication session on a first network, ignoring pages from a second network during the communication session, the first and second network configured for operation on different physical layers, and upon termination of the communication session over the first network, selectively sending a query to an application server to request information related to failed attempts by the application server to contact the access terminal on the second network during the communication session.
Abstract:
A method of determining, within a radio network, an optimal value of at least one network parameter having an associated performance metric, the network having at least a base station and a user equipment (UE), the method including: providing a mathematical representation function (MRF) for the performance metric such that an optimal value for each of the at least one network parameter provides a result of zero in the MRF; making at least one noisy observation of the MRF from the network; and recursively updating the at least one network parameter based on the at least one noisy observation to obtain the optimal value for each of the at least one network parameter that provides the result of zero in the MRF.
Abstract:
An embodiment is directed to an application server configured to set-up a communication session within a wireless communications system. The application server receives, from a session originator, a request to initiate the communication session with a set of session targets, and then transmits one or more call announcement messages for announcing the communication session to the set of session targets. The application server determines information associated with a probability that the set of session targets will fail to accept the announced communication session, and/or delay information associated with when call responses will arrive from the set of session targets in response to the one or more call announcement messages. The application server selectively grants a floor of the communication session to the session originator based on the determined information.
Abstract:
A user equipment (UE) determines to activate a data session. The UE configures a data session activation request message to include an indication of an association with communication sessions of a given type (e.g., delay-sensitive communication sessions), and then transmits the data session activation request message to an access network. The access network determines to establish an aggressive paging cycle of a downlink channel for the UE based in part upon receiving a message (e.g., which can be different than the data session activation request message) that conveys the indication of the association to the access network. The access network sends at least one instruction for facilitating an allocation of the aggressive paging cycle to the UE, and the UE receives the at least one instructions and monitors the downlink channel accordingly.
Abstract:
Methods and systems for sending multicast messages are disclosed. A multicast message is received to be transmitted to a plurality of access terminals at a radio access network (RAN), the received multicast message having a first format. The first format may correspond to a conventional multicast message format. The RAN determines whether the received multicast message requires special handling. If the RAN determines the received multicast message requires special handling, the radio access network converts the received multicast message from the first format into a second format. The RAN transmits the converted multicast message with the second format (e.g., a data over signaling (DOS) message) on a control channel to at least one of the plurality of access terminals. The access terminals receiving the converted multicast message interpret the message as a multicast message.
Abstract:
In an embodiment, a UE determines to transmit a message (e.g., an alert message, a call initiation message). Based on the type of the message to be transmitted, the UE selectively transmits supplemental data configured to prompt an access network to transition the UE to a dedicated channel state (DCS). In another embodiment, an application server configured to arbitrate communication sessions between UEs receives a message for transmission to a target UE. Based on the type of the message to be transmitted to the target UE, the application server selectively transmits, to a serving access network of the target UE, supplemental data configured to prompt the serving access network to transition the target UE to the DCS. In another embodiment, the access network selectively transitions a target UE to the DCS based on whether differently sized messages are received at the access network for transmission to the target UE.
Abstract:
Aspects of regulating broadcast overhead messages within a wireless communications network are disclosed. In an example, an access network periodically sends a message advertising an announced multicast session on each of a plurality of carriers, the message indicating that the announced multicast session is being carried on a target carrier among the plurality of carriers. The access network determines whether to cease transmission of the periodic message within each non-target carrier based on a number of times the periodic message has been sent in each of the plurality of carriers, and ceases transmission of the periodic message within each non-target carrier based on the determining step.
