Abstract: A range between a first wireless device and a second wireless device is estimated using a first mechanism based on messages transmitted over a first communication channel. The first communication channel is associated with a first radio access technology capability of the wireless devices. One or more metrics indicative of an accuracy of the range estimates provided by the first mechanism are obtained. A second mechanism to estimate a range between the first wireless device and the second wireless device may be implemented in favor of the first mechanism when the metric fails to satisfy a criterion. The second mechanism is based on unicast messages transmitted over a second communication channel. The second communication channel is associated with a second radio access technology capability of the wireless devices and may be the same as, or different from, the first communication channel.

Abstract: A selection server device may receive a first registration request and determine that a user device is associated with a non-local call service control function (CSCF) server device and that the user device is located outside of a service area associated with the non-local CSCF server; output a non-preferred server indication to the non-local CSCF server device to cause the non-local CSCF server device to be disassociated with the user device; receive a second registration request from the user device; determine that the user device is not associated with any CSCF server; and output the second registration request to a local CSCF server device, associated with a service area in which the user device is located, to cause the local CSCF server device to register the user device with the local CSCF server device.

Abstract: A method of establishing communication between mobile terminals includes receiving a communication request from a caller terminal, the communication request including at least a caller number and information for determining an identification code of a callee terminal, the information including a number of the callee terminal or an owner name of the callee terminal. The method also includes obtaining the identification code of the callee terminal based on the information and inquiring about a corresponding record associated with the caller terminal and the callee terminal by use of a pre-stored address book referencing relationship and a communication history, based on the caller number and the identification code of the callee terminal. The method further includes computing a communication right value based on the corresponding record and determining whether the computed communication right value exceeds a pre-determined threshold.

Abstract: A system and method provides communication between subscribers of a telephone network and the subscribers of an OTT provider website wherein each of the subscribers of the OTT provider website is assigned a telephone number in a block which is not assigned to any particular country. The system includes terminating a call (e.g., having voice, video, data, and/or messaging) from the telephone network directed to a number in the block, and passing the terminated call to a nearby entry point to the OTT provider website, the OTT website being configured to associate the incoming call with the user's account to which the called number has been assigned. Calls can be placed in the opposite direction, in which case the assigned number is passed into the telephone system as the calling party's number.
