摘要:
A core network element (102) is configured to facilitate establishment of a first type of wireless communication resource, such as a dedicated channel, to facilitate communication with first communication target. The core network element detects a first message using a second type of wireless communication resource, such as a common channel, where the first message is a part of the request for the first communication resource. The core network element also detects within the first message a second message requesting establishment of a first type of wireless communication resource with the at least first communication target. As the result of the first and second messages, the first type of communication resource is established with the at least first communication target, such as a push-to-talk mobile station. The target mobile station will respond with a message indicating that it is either unavailable or not unavailable. If the network control element detects that the target communication unit is unavailable, then it proceeds to break down the establishing of the first type of communication resource. Otherwise, a message is delivered to the originating communication element (114) indicating that the first communication resource is established.
摘要:
A receiving buffer (110) in communication with a processing circuit (150) stores (310) received packets of data while the processing circuit (150) strips (320) the frames of data from the packets. The stripped frames are stored (330), and the processing circuit (150) creates and stores (340) reformed packets using the frames. Preferably, the processing circuit (150) creates the reformed packets according to one or more certain predefined functions of one or more conditions monitored by a condition monitor (130) which indicate the possible size of the next available radio frame in which the packets are wirelessly transmitted. Then, the processing circuit (150) sends the reformed packet that ideally matches the size of the radio frame to be sent with the radio frame.
摘要:
A system and method for reducing the transmission delay of messages sent through a network from a source mobile unit (112) to a destination mobile unit (114). Portions of a data message are received (202). The portions of the data message are decoded (204) and a type of the data message is determined from the decoded portions. Before the entire data message has been received, processing and service actions are performed as a result of receiving the data message (206) based at least in part upon the type of the data message.
摘要:
A server (101) designates and assigns each of a plurality of communication devices to at least one of a plurality of groups. The server (101) prepares a communication having presence information corresponding to a status of the communication devices in the group; determines network infrastructure device(s) serving the group; and transmits, at a pre-determined time, the communication to the network infrastructure device(s). A network infrastructure device (103a-c, 105a-f) receives the communication and transmits, as a common channel signal during the pre-determined time, a signal with the presence information. A communication unit (107a, 107b, 107c) receives an indication of the pre-determined time; transmits, at an interval proximate to the pre-determined time, a signal indicating the communication device's status; and receives, at the pre-determined time, the signal with the presence information.
摘要:
A page request (112) is received. When a user preference is not up-to-date, a non-acceptance message (116) is appended to a page response (114) and channel assignment is altered when the page response (114) includes the non-acceptance message (116).
摘要:
A method and computer program for initiating a message to a radio access network include steps of: (404) detecting a request to transmit a probe message from a transmitter over an access channel to a radio access network; (406) calculating a transmit power for the probe message; (408) checking a condition that may result in failure to receive the probe message over the access channel by the radio access network; and (410) when the condition is determined to be true, then (412) reducing a message length of the probe message to generate a shorter probe message; (414) recalculating the transmit power to send the shorter probe message; and (416) transmitting the shorter probe message over the access channel at the recalculated transmit power.
摘要:
Various embodiments are described which can provide reduced PTT call setup times and a greater degree of service integration for PTT users. A PTT originator's MSC (171) notifies (205) the PTT server of a PTT session request before the originator (101) has the channel and data connection resources to send a PTT session request itself. This enables the PTT server (161) to trigger (207) the establishment of channel and data connection resources for the PTT target (102) before the originator is able to trigger the same by sending a PTT session request itself. Also, the target's MSC (172) notifies (221) the PTT server after the target responds to a page for the session, enabling the PTT server to indicate PTT session acceptance (223) on behalf of the target before the target has the channel and data connection resources to respond to a PTT session request.
摘要:
A core network element in a communication system can serve to store information regarding a present communication location of a given communication unit that seeks to facilitate a wireless communication using one kind of wireless communication resource (such as a dedicated voice channel) via another kind of wireless communication resource (such as a shared data channel). Upon receiving an indication from a communication unit regarding a target communication unit, the core network element can also make a determination regarding the likely availability of that target communication unit. A corresponding message that corresponds to this likelihood of availability can then be returned to the communication unit (using, preferably, the previously stored communication location information to essentially target the use of system resources to effect delivery of this message). The communication unit, in turn, can use this preliminary indication to facilitate its own subsequent actions.
摘要:
A method of messaging in a wireless cellular system comprising predicting a location of the mobile station (122, 124), wherein the location corresponds to a first sector within the wireless cellular system; sending a first message to the mobile station via the first sector within the wireless cellular system; and sending a second message corresponding to and having a reduced size as compared to the first message to the mobile station via a second sector at approximately the same time as the first message is sent via the first sector.
摘要:
Various embodiments are described to provide push to talk (PTT) talk permit notification (TPN) with less average delay, given a desired rate of falsing, than prior art systems can achieve. A first communication system device (e.g., 101, 121, or 161) determines (504) whether one or more conditions are present for a PTT call that decrease the likelihood of successfully establishing the call. If (506) one or more conditions are present or a querying delay is expected to be less than an acceptable delay amount, the first device queries (508) a second communication system device (e.g., 121, 161, 122, or 102) for an indication to proceed with a TPN for the call before providing the TPN. Otherwise, the first device provides (512) the TPN without waiting for an indication to proceed with the TPN from the second device.
