  • Patent number: 8358999
    Abstract: Systems and methods for providing dispatch call features are provided. The dispatch call features include the ability to maintain multiple simultaneous dispatch calls and the ability to manage multiple dispatch stations. The maintenance of multiple simultaneous dispatch calls feature allows a dispatch station to place a current dispatch call on-hold to either initiate a new dispatch call or to accept an incoming dispatch call. The management of multiple dispatch stations feature allows a number of dispatch stations to be associated with one or more dispatch station identifiers. When a dispatch call is made to one of the dispatch station identifiers, all associated dispatch stations are paged. The first dispatch station to respond to the page is connected to the incoming dispatch call.

  • Patent number: 8346250
    Abstract: A method and system is disclosed for enhanced Simultaneous Hybrid Dual Receive operation. A hybrid access terminal engaged in an IS-856 data communication in a hybrid IS-2000/IS-856 wireless communication system will use its high-gain antenna to conduct IS-2000 tuneaway scans when the access terminal determines that the IS-2000 signal received from its serving base station is below a level that can be reliably detected by its low-gain antenna. At the same time, the access terminal will continue to use its low-gain antenna to engage in the ongoing IS-856 communication, thereby avoiding interruption of the IS-856 communication by IS-2000 tuneaway scans, even when RF conditions are sub-optimal. The access terminal may apply a DRC offset to its DRC request when using just its low-gain antenna for IS-856 communications.

  • Patent number: 8346314
    Abstract: The slot cycle index is currently negotiated by a mobile handset and a base station. However, if the slot cycle index could be selected dynamically a mobile handset that operates more efficiently for the user would result. Talk time could be maximized when the battery, or other mobile power source is low, while connect time for a mobile call could be minimized when the battery is near fully charged or at times when the user is likely to make a mobile call. Additionally, location could be used to determine the likelihood that the user will make a mobile call. However, current network usage would typically need to be considered when determining if the slot cycle index should be changed. Mobile handset users could also charged for quicker response times, or mobile handset users on more expensive plans could be given typically faster response times. Many different things can be considered in determining when to adjust slot cycle index, such as, for example, battery power, time of day, or system loading.

  • Publication number: 20120276939
    Abstract: A method and apparatus for that provides a re-entry procedure following a radio frequency outage in a wireless communication network is disclosed. The method includes providing (204) a entity identification for a base station (102-106) or a paging controller (108) to a mobile station (110) during initial entry of the mobile station to a wireless communication network. The method also includes storing (206) mobile station context information at an entity corresponding to the entity identification. After a radio frequency outage occurs after the initial entry of the mobile station into the network, a notification is sent (218) that indicates that the mobile station is re-entering the wireless communication network. Based on the notification that there has been a radio frequency outage, the mobile station context information is obtained (220) to assist the mobile station to re-enter the wireless communication network.

  • Patent number: 8301175
    Abstract: A method of controlling paging flow in a network for cellular communications is described, which comprises the steps of: at a control node, receiving a request for paging a mobile station; determining a location area in which the paging shall be performed; checking whether the number of paging transactions which are ongoing for the location area is lower than at least one maximum number of ongoing paging transactions allowed for the location area; after a determination that the number of ongoing paging transactions is lower than the maximum number, updating the number of ongoing paging transactions for the location area and processing the paging request. Preferably, if the number of ongoing paging transactions is not lower than the maximum number, it is checked whether the paging request is a particular LCS transaction and, if so, the request is placed in a buffer and served with priority as soon as the number of ongoing paging transactions returns to be lower than the maximum number.

  • Patent number: 8290519
    Abstract: Methods and systems are described for providing a presence service that is useful for mobile telecommunications devices. A plurality of outgoing presence updates are sent to a presence client. The system monitors the level of network traffic and determines whether the client is in a region of high network load, and if so, the system throttles the outgoing presence updates during the condition of high network load. The level of throttling may depend at least in part on the amount of time that has elapsed since the presence client began a presence session, and/or the amount of time that has elapsed since an incoming presence update was received from the presence client. In determining the latter amount of elapsed time, the system may consider only the amount of time elapsed since an incoming non-automatic presence update was received from the presence client.

  • Publication number: 20120252517
    Abstract: Methods and apparatus for triggering and synchronizing a machine type communication (MTC) device are described. MTC devices may operate in a time controlled mode, where the MTC device attaches to a network at specified intervals to report to a network. The time controlled mode may include two time controlled cycles, a reporting cycle and a control cycle. Methods are also described for communicating the reporting and control cycles between the MTC device and the network or MTC server. These cycles may be communicated on an application layer, by an MTC server using an MTCsp interface or via MTC configuration. In addition, triggering cycles may be sent via the Non-Access-Stratum (NAS) layer by extending discontinuous reception (DRX) cycles or by allowing a network to send the cycles over a broadcast channel by defining new System information block (SIB) information.

  • Publication number: 20120252518
    Abstract: A method and apparatus for network initiated attachment are provided. A machine-type communication (MTC) wireless transmit/receive unit (WTRU) is in a detached state. A MTC server sends a trigger request to the MTC WTRU via a network entity, such as a Home Subscriber Server (HSS), a mobility management gateway (MME), a Serving General packet radio service Support Node (SGSN), or a combination thereof. The network entity stores, updates, or obtains information associated with a current, former, or default connection status of the WTRU. The information is obtained from the WTRU attach request message, subscription information, locally stored information, or a combination thereof. The subscription information includes a subscription profile. The WTRU, upon receiving the trigger request, performs a network attachment procedure, enters an attached state and communicates with the MTC server. The WTRU performs a network detach procedure and enters a detached state after completing communications with the MTC server.

    Abstract: A terminal device free of interference between an RACH and a PUSCH or the like even when a base station device with a large coverage is installed. In the device, a configuration number extraction unit (103) extracts a configuration number from a BCH received by a BCH reception unit (102). A control unit (104) determines the corresponding RACH format (the necessity of repetition, the CP length TCP, the second preamble length TPRE2, and the GT length TGT) according to the configuration number, notifies a repetition unit (109) of the result of the judgment of necessity of repetition, notifies the repetition unit (109) of the second preamble length TPRE2, notifies a CP addition unit (110) of the CP length TCP, and notifies a GT addition unit (112) of the GT length TGT. When the repetition unit (109) receives the notification of performing the repetition, it performs the repetition according to the second preamble length received from a TPRE2 determination section (154).
