Abstract: To communicate in a press-to-talk (PTT) session, a message for requesting a right to talk in the PTT session is sent over a wireless link between a mobile station and a base station system. The message for requesting the right to talk in the PTT session is sent in wireless signaling over the wireless link. An acknowledgment of the wireless signaling carrying the message is received, with the acknowledgment sent by the base station system in response to the control signaling. An indication is provided at the mobile station of the right to talk in response to the acknowledgment.

Abstract: Various methods for effectively detecting the discontinuous transmission (DTX) mode are provided both from the physical layer perspective and from the medium access layer (MAC) perspective. The DTX mode transmission on reverse supplemental channels is detected by comparing a transmitted and a received power ratio of a pilot channel and a supplemental channel. For a reverse link communication, the DTX mode transmission is detected on dedicated control channels. The DTX mode transmission on a forward link supplemental channel can also be detected by monitoring both the transmitted and received power ratios of a primary power control channel and the supplemental channel. As an alternative to or in combination with the above mentioned methods, in order to monitor the DTX mode, a new network parameter is introduced which requires a change in the IS-2000-3 standard. This parameter acts as an indicator signaling to a receiver, from the MAC layer, that the transmitter has entered into the DTX mode.

Abstract translation: 从物理层的角度出发，从媒体接入层（MAC）的角度提供了用于有效检测不连续传输（DTX）模式的各种方法。 通过比较导频信道和补充信道的发送和接收功率比来检测反向补充信道上的DTX模式传输。 对于反向链路通信，在专用控制信道上检测DTX模式传输。 前向链路补充信道上的DTX模式传输也可以通过监视主功率控制信道和补充信道的发送和接收功率比来检测。 作为与上述方法的组合的替代方法，为了监视DTX模式，引入了需要IS-2000-3标准的改变的新的网络参数。 该参数用作从MAC层向发射机进入DTX模式的接收机的指示信号。

Abstract: An extended global service redirection message (EGSRDM) is provided within the standards for mobile communications networks, where the EGSRDM supports multiple band class records within the common fields. The base station generates an EGSRDM with multiple band class records, with each band class assigned specific frequencies. When a mobile station (MS) receives the EGSRDM, the MS compares the parameters of the various band classes (frequency, ACCOLC, P_Rev) with those supported by the MS, and generates a list of the band class(es) from those provided within the EGSRDM that are supported by that MS. The MS then selects the first band class within the list and selects a frequency within the selected band class to assign to MS communication. When none of the frequencies within the selected band class is available, the MS selects the next band class within the created list and selects a frequency from the next band class.

Abstract: In code division multiple access communication systems, there are three levels for updating locations of dormant mobile stations (MSs) and setting up fast call. In sector and are levels, the dormant MS send a layer 2 message containing a message type and MS identifier to a base transceiver station (BTS). Since the message is associated with the sector where the MS is located, the network is aware of the MS's location from the updated location. The dormant MS sends to the BTS a reconnect message containing a message type and an MS identifier. The MS's dormant to active state transition is initiated by the MS. In the communication network, sub-packet zone ID is broadcasted in the overhead message. The MS reports its location change on R-CSCH and the network with the BSC level control can page the MS within the zone where the MS sends the report.

Abstract: In a wireless communications network, a method of performing a location service with respect to a mobile station includes communicating a paging message containing an indication of whether the paging message is related to at least one of an emergency-related location service and a law enforcement-related location service. In another aspect, a mobile station in a wireless communications network communicates messaging to move the mobile station to a traffic channel in response to a callback by at least one of an emergency services entity and a law enforcement entity. The mobile station also receives a location request on the traffic channel, the location request containing an indication of whether the location request is related to at least one of an emergency-related location service and a law enforcement-related location service.

Abstract: A packet data service node (PDSN) is formed to establish a connection with a plurality of mobile terminals by way of one or more packet control function cards or devices. A packet control function (PCF) card or device is formed to provide an interface between the packet data domain and wireless domain and further to inform a base station controller/access network controller (BSC/ANC) to block the setup and establishment of any additional communication links in a specified manner until the overload condition ceases to exist. More specifically, the PCF receives loading information from each PDSN to which it is connected and determines a composite loading factor. The PCF transmits the composite loading factor to the BSC/ANC periodically or if the loading factor exceeds a specified threshold and call blocking should be initiated for packet data calls for a select group of mobile terminals.
