In an embodiment, if service on both first and second networks is available, an access terminal negotiates with an access network to establish a paging cycle for the first network (e.g., 1x EV-DO) and a first dynamic paging cycle for the second network (e.g., CDMA2000 1x). If service on the second network is maintained but service on the first network becomes unavailable, the access network negotiates a second dynamic paging cycle (e.g., more aggressive or shorter than the first dynamic paging cycle) for the second network. If the access terminal determines that service on the second network is maintained and service is again available on the first network, the access terminal re-negotiates the first dynamic paging cycle for the second network. Accordingly, paging cycles on the second network are dynamically adjusted based on a service availability status of the first network.

In an embodiment, an originating device sends a request, to a server, to initiate a full-duplex session with a target device. Responsive to the full-duplex request, a half-duplex session is set-up from the originating device to the target device before the full-duplex session is set-up. The target device indicates its acceptance of the half-duplex session, receives half-duplex media from the originating device and selectively indicates its acceptance of the full-duplex session. In another embodiment, during a session currently supported either by half-duplex or full-duplex, the server arbitrating the session receives a request from one of the session participants to transition the session to another duplex-type. The server then selectively transitions the duplex-type of the session.

Systems and methods for hybrid call setup in a wireless communication system are disclosed. A page is sent on a first network informing a target device of a pending communication on a second network. The page also informs the target device a short data burst (SDB) will be sent on the first network. The short data burst (SDB) is sent on the first network containing setup information regarding the pending communication on the second network.

In an embodiment, an access network (AN) receives a message configured to prompt a conditional allocation of Quality of Service (QoS) resources to an access terminal (AT). The message can be received from the AT or from an application server (AS) that arbitrates a communication session for the AT. In another embodiment, if the AT determines that a QoS resource request has not yet been granted, the AT waits until the traffic channel (TCH) has been obtained for a communication session before resending the QoS resource request. In another embodiment, if the AT determines to initiate or join a second communication session before a confirmation that QoS resources for a first communication session are relinquished, the AT waits until the confirmation is received before a request for QoS resources for the second communication session is sent.

Embodiments are directed to media forwarding for a group communication session within a wireless communications system. A server receives a frame for a given timeslot from each of a first plurality of access terminals participating in the group communication session, each of the received frames having an associated data rate. The server selects at least one and less than all of the received frames based at least in part on the associated data rates of each of the received frames. The server sends the selected at least one frame to a second plurality of access terminals participating in the group communication session.

Systems and methods for processing a data over signaling (DoS) message at an access terminal are disclosed. A message is received at an access terminal. The message is decoded to determine if it is a DoS message. Upon detecting the DoS message a sleep delay timer is set to prevent the access terminal from entering a sleep state for a predetermined time.

An apparatus and method for efficiently updating location information of a mobile device in a wireless communication network, such as a cellular network, is disclosed. The mobile device sends a location message over an access channel. The wireless communication device continually transmits a location message at periodic intervals without regards to the status of the base station in communication with the wireless communication device. The base station determines a timeslot in which to receive a location message transmitted by the wireless communication device. If more than one wireless communication device is transmitting a location message, the base station prioritizes the order in which to receive the location message, opening the first available timeslot to the higher priority wireless communication device. A high priority device may be a wireless communication device used by emergency services personnel, such as firefighters or the police.

In an embodiment, an access terminal sends a request for a level of Quality of Service (QoS) resources to an access network, the QoS resource request associated with a call attempt by the access terminal. The access terminal proceeds with call set-up for the call attempt irrespective of whether the access network grants the QoS resource request. Alternatively, the access terminal waits for an extended period of time before the call attempt is permitted to fail. In a further example, in the event of call failure, the access terminal can refrain from informing a user thereof of the call failure. In another embodiment, the access network can respond to the QoS resource request with an allocation of a lower level QoS resources than requested if the requested QoS resources are not available. The access terminal can likewise be permitted to participate in the call with the lower level QoS resources.

Embodiments are directed to determining whether one or more physical user interactions are present, at a wireless communication device, that indicate a near-future potential communication session resource request. Before the determination, a communication interface of the device is in a dormant state characterized by the device not being permitted to engage in a communication session with a wireless communication network. The device transitions the communication interface, after the determination, from the dormant state to an active state. In the active state, the device performs one or more actions to reduce a delay associated with a transmission of the potential communication session resource request in the event that the potential communication session resource request is actually transmitted by the device. For example, in the active state, the device can power-up or wake-up a radio bearer or modem to reduce a delay before transmission of the potential communication session resource request.

Aspects of mobile communication for establishing a receive-only group communication, such as a Push-to-Talk (PTT) call or multicast call with a plurality of wireless communication devices that are in a receive-only mode are disclosed. When a group call between wireless communication devices starts from an originating device, in one embodiment indicating a receive-only group with which a group call is to be established, one or more receive-only wireless communication devices are determined and invited to participate in the group call. The traffic channel to the receive-only wireless communication device is transitioned to a uni-directional, forward-only traffic channel such that media is provided from the originating wireless communication device to the receive-only wireless communication device via the uni-directional traffic channel.

A system and method for optimizing call setup latency for geographically dense groups including updating client location information using at least one application server while the client moves from one sector to another to provide a location update; identifying and updating parameters including location update information uniquely identifying a sector from which a client is receiving communication service; and determining at least one geographically dense call group; and choosing at least one designated responder to the at least call group. A client per cluster is selected as a designated responder for that cluster and when the server needs to set up a geographically dense group call, a random number is included corresponding to the designated responder for that group in a call setup message.
