Method and arrangement in a radio communication system

A method and device for measuring signal strengths by mobile stations in a wireless communication system are provided with minimal complexity. More particularly, while transmitting and receiving on a channel, scheduled signal strength measurements may be required. For instance, the received signal strength of broadcast information slots at the beginning of a superframe may be measured at predetermined times for several carriers. Also, the required signal strength measurements may be scheduled by a mobile station at times which minimize interference with the tasks of transmitting and receiving messages. Scheduled signal strength measurements may be delayed when the mobile is transmitting and receiving on a channel, and then more frequent signal strength measurements may be made when there is no communication. In other words, the signal strength measurements do not have to occur uniformly in time, but may be more frequently performed if they have been delayed.

Inhibiting and controlling signal strength measurements by a mobile

A method and device are provided for of supporting a plurality of mobile station operation modes in a wireless communication system by user control. Presently, communication protocols exist for supporting end user equipment which operates in a single mode of operation. However, it is desirable to combine protocols from various technologies to form end user equipment which operates in multiple modes of operation. Thereby, the present method allows the mobile station to operate in a multi-mode environment where a user can invoke a certain mode.

Operating mobile stations of wireless communication systems in multiple

A method for reassigning mobile stations a new phase within a channel is disclosed. In a communication system, a plurality of mobile stations attempt to communicate on a limited number of channels. The invention first uses a general allocation method to approximately evenly distribute the mobile stations on the available channels. After a mobile station begins active communication on the system, a second allocation method is used to change the phase of some mobile stations on a channel which has become heavily loaded. In addition, a message can also be sent to mobile stations assigned to but not yet actively communicating on the heavily loaded channel indicating that the mobile stations should change to a new channel.

Bandwidth allocation

A method, and associated apparatus, of providing a communication station with anonymous access to a communication network to communicate data therein. Access is provided to the communication station only after authenticating that the communication station is authorized to communicate in the network, but access is provided without individually identifying the communication station to the network with a permanent identifier unique to the communication station.

Method and apparatus for providing anonymous data transfer in a

Apparatuses and mobile stations are described which provide packet data services in TDMA (Time Division Multiple Access) cellular systems, based on providing shared packet data channels optimized for packet data. A first 'integrated' embodiment utilizes the current cellular infrastructure to the extent possible consistent with functional and performance requirements. Shared packet data channels in base stations may be provided dynamically determined by demand. A packet data controller in each Mobile services Switching Center controls access to the packet data services. A packet data router in each MSC routes packets to and from the MSC service area. A backbone network interconnects packet data routers and Interworking Functions providing internetworking with external network(s). A second 'separate' embodiment, in order to minimize the impact on the current cellular system, primarily utilizes the base station portion of the cellular system, relying for the remaining network parts on a separate mobile packet data infrastructure.
