A mobile station for use in an IS-2000-compatible wireless network. The mobile station is capable of receiving data from a first base station of the wireless network simultaneously in a first code division multiple access (CDMA) channel and a second CDMA channel. The mobile station transmits a capability message to the first base station, the capability message comprising a field indicating that the mobile station is capable of simultaneously operating in a Forward Packet Data channel (F-PDCH) and a Forward Supplemental channel (F-SCH).

The invention provides an electric energy collecting and running management system on the basis of a station area concentrative service terminal, and a method thereof. The electric energy collecting and running management system is provided with a master system, a station area concentrative service terminal, an electric energy meter collector, a station area electric energy meter and a resident electric energy meter; the master system is in charge for services such as data collecting, processing, managing and analysing, output and the like; the running state of the system is monitored and undated; two communication channels such as GPRS or CDMA and RS232 are used between the master system and the station area concentrative service terminal; the station area concentrative terminal has the functions of distribution transform monitoring, electric usage site management, meter concentrator meter reading and the like; the downlink selects a RF narrowband wireless radio frequency data transmission / power carrier / RS483 interface to be communicated with the electric energy meter collector; meter reading task is sent down to the electric energy meter collector; the terminal collects the electric meter information read by various collectors and analyses all electric meter information; and the uplink transmits all data to the master system by the GPRS / CDMA channels.

In one embodiment, a multi-carrier CDMA network grants radio link resources to a mobile station by maximizing soft handoff conditions, by preserving frequency continuity with the mobile station, or by load balancing across carrier frequencies in two or more cells, or by some combination thereof. The network identifies carrier frequencies having two or more CDMA channels for assignment to the mobile station. If one of those frequencies was used by the mobile station to request resources, it may be advantageous to select that frequency; otherwise or instead, the choice is narrowed to the carrier frequency or frequencies having the greatest number of available radio links. From that point, the choice may be further narrowed, for example, by selecting the carrier frequency having the most favorable CDMA channel loading across two or more cells. In another embodiment, such multi-carrier load balancing is the basis of carrier frequency selection.

A method and system for providing acknowledgment and / or data rate control (DRC) information with respect to data packets conveyed on a plurality of active forward link (FL) carriers. The number of reverse link (RL) carriers employed for the acknowledgment and / or DRC information may be less than the number of active FL carriers, and may be a single carrier, even when the signaling protocol is, in the limit, consistent with presently-supported standardized CDMA protocols. Code multiplexing techniques are employed inventively to convey information for up to fifteen FL carriers on a single, standard CDMA channel designed to provide such signaling for only a single FL carrier at a time.

Aspects of a method and system for servicing a plurality of users via a plurality of femtocells are provided. In this regard, a cellular enabled communication device may receive portions of a datastream from a plurality of femtocells, reconstruct the datastream from the received portions of the datastream, and process the reconstructed datastream for presentation to a user of the cellular enabled communication device. The received portions may be buffered in the cellular enabled communication device. The portions of the datastream may be associated with a plurality of CDMA channel access codes. The portions of the datastream may be received via a plurality of cellular frequencies. The portions of the datastream may be received during a plurality of TDMA timeslots. Portions of the datastream may be received from a cellular base station. Portions of the datastream may be received from a WiMAX base station.
