  • Publication number: 20100110987
    Abstract: An access terminal may switch to a different mode of wireless network selection as a result of manual selection of a wireless cell set (e.g., a closed subscriber group) associated with one or more wireless cells. For example, if the user of an access terminal selects a closed subscriber group in a wireless network that is different than the current wireless network, the access terminal may enter a manual mode of wireless network selection, select the wireless network corresponding to the closed subscriber group, and register on a closed subscriber group cell in the selected wireless network. In addition, an access terminal may automatically switch to a different mode of wireless network selection (e.g., the prior mode) upon losing coverage of a wireless cell set. An access terminal may also automatically select a cell of a wireless cell set if the access terminal returns to a cell of the cell set within a defined period of time after losing coverage of the cell set.

  • Publication number: 20100112980
    Abstract: Systems and methodologies are described that facilitate supporting multiple access modes for a base station in a wireless communication environment. The base station can leverage hybrid, closed, or open access mode. A whitelist of a mobile device that successfully registers on the base station can be selectively updated to include a CSG ID of the base station. For example, the CSG ID of the base station can be added to the whitelist when the base station operates in closed access mode, while adding the CSG ID can be skipped when the base station operates in hybrid access mode. According to another example, the CSG ID can be selectively added based upon a received accept cause value. Additionally or alternatively, a CSG ID and an access mode indicator can be transmitted from a base station to a network node for implementing access control and/or paging optimization at the network node.

  • Publication number: 20090253403
    Abstract: Techniques for supporting eCalls are described. In an aspect, an eCall indicator may be used to indicate an eCall being established. In one design, a terminal may generate a message including an eCall indicator and may send the message to originate an eCall. The eCall indicator may indicate (i) whether or not a call is an eCall or (ii) whether an eCall is initiated automatically by the terminal or manually by a user. In another aspect, a terminal may avoid sending signaling for mobility management and connection management to wireless networks except for eCalls and designated calls. The terminal may avoid performing location updating, performing registration, responding to paging requests, etc. The terminal may exchange signaling with a wireless network for an eCall initiated by the terminal. After the eCall is initiated, the terminal may perform location updating with the wireless network and call establishment for the eCall.

  • Publication number: 20080281858
    Abstract: Electronically creating an itinerary schedule in a calendar program. A geographic indicator and a calendar date are acquired and coordinated with each other to define an itinerary entry. The itinerary entry is included into a calendar program maintained by the machine. The step of acquiring the geographic indicator further comprises the step of updating a counter upon each selection of a geographic indicator. Another method electronically populates a calendar program with an event using an itinerary entry. Optionally, health care providers from within a geographic indicator are included in the itinerary entry. A geographic indicator and calendar date are obtained from an itinerary entry, and additional search criteria are input. A search of a database is executed to identify candidates matching the geographic indicator and search criteria. Candidate matches are assigned to a time slot, and each time slot is populated into the calendar program on the calendar date.

  • Publication number: 20070266089
    Abstract: Techniques for archiving data exchanged between a terminal and a wireless communication network during a session are described. Session data may be archived at a network entity in real-time while the session is in progress or may be uploaded to the network entity for archival after the session has terminated. The network entity may archive all data exchanged during the session or only data of the terminal, depending on whether authorization is received from other terminals in the session. The network entity may assign an identifier for the session and may store the identifier and other attributes for the session. During or after the session, the network entity may receive from the terminal a request for all or a portion of the archived data and would then provide the requested data. The network entity may archive a single copy of the session data for all terminals in the session.

  • Publication number: 20060212526
    Abstract: A method and apparatus for implicit floor control in push-to-talk over cellular system. A message is generated by a client in a communication system and is then streamed to a push-to-talk server. The server checks to see if the floor is idle, and if so, distributes the message to at least one other participant in the communication session. If the floor is not idle, the new message is stored and queued for distribution after all other messages ahead of the last received message have been distributed.

  • Publication number: 20060212525
    Abstract: A method and apparatus for interworking between push-to-talk over cellular (PoC) systems and instant messagaing (IM) systems is provided. An interworking entity that behaves like a PoC client to a PoC server and as an IM client to the IM server is provided. The interworking entity may be implemented as part of the PoC server or the IM server. The interworking entity listens to talk bursts from the PoC server and when it receives a talk burst the interworking entity sends the message to the IM client via the IM server. In an embodiment, the interworking entity listens to talk bursts or audio clips from the IM server and when it receives them, stores them in a temporary storage memory and converts them to a streaming format. The interworking entity then requests the floor from the PoC server, and, once the floor is granted, streams the stored audio clip or talk burst to the PoC server. The PoC server then distributes the clips to the PoC clients.
