A system and method of providing caller identification (ID) over a public switched telephone network (PSTN). For outbound calls, the system and method enable a caller to provide a caller ID that differs from the native caller ID of their mobile phone. The system and method enable multiple phones tied to a single account to display the same caller ID for outbound calls. For forwarded inbound calls, such as calls being forwarded from an office, the system and method inform the recipient of the identification of the call as well as that the call is being forwarded. The system and method enable the recipient to have calls forwarded from more than one number and identify the identity of the caller as well as the specific number the call is being forwarded from.

A method applicable to a multi-subscriber identity module (SIM) call management process includes parsing, by a managed device, an incoming call to obtain call information, determining a communications circuit corresponding to a called identifier, and when the managed device has performed an incoming call shielding setting on the communications circuit in response to a remote management instruction sent by an entitlement server (ES), skipping responding, by the managed device, to an incoming call event, or receiving, by the server, a remote management instruction from the ES, and deleting or freezing routing information corresponding to an identifier in response to the remote management instruction such that a communications circuit corresponding to the identifier in the managed device is unable to respond to an incoming call event.

A system and method for establishing communications enables an outbound communication to be made simultaneously across a plurality of different communications platforms. The system is configured to perform the following: receive from a user, a first request to establish an electronic communication with a contact; identify via the details of contacts stored in a storage device, a contact identifier of the contact for each of a plurality of the different electronic communications platforms; receive at a processor from the user, selected devices of the user with which to establish the electronic communication with the contact; transmit via one of the selected devices of the user, a second request to establish an electronic communication comprising real time audio data with the contact simultaneously via each of the plurality of the different electronic communications platforms using each respective contact identifier; receive via the communications device, an acceptance of the second request to establish an electronic communication with the contact via one of the plurality of different electronic communications platforms; and establish an electronic communication comprising real time audio data between the contact and the one of the selected devices of the user via the one of the plurality of different electronic communications platforms.

A first electronic device receives a phone call that was routed to the first electronic device by a call-routing service. While receiving the call, the first electronic device receives a request to route the phone call to a second electronic device. In response to receiving the request to route the phone call to the second electronic device, in accordance with a determination that a first routing criteria have been met, the first electronic device sends a request to the call-routing service to route the phone call to the second electronic device instead of routing the phone call to the first electronic device. In accordance with a determination that a second routing criteria have been met, the first electronic device causes call data associated with the call to be routed through the first electronic device to the second electronic device.

Disclosed embodiments provide improved communication between a caller and multiple parties. A caller performs a call spray operation on a group of contacts using an electronic communication device such as a mobile telephone. The call spray operation attempts to contact an electronic device associated with each contact in the group of contacts. If one of the contacts answers and is deemed to be a live user, then the remaining contacts that did not answer each receive a message on their associated electronic device indicating which of the contacts answered the caller with a live user. In this way, a group of people can be conveniently contacted and kept up to date with the status of the communication with the caller.

The invention provides a decryption method for a trunking group call and a user equipment. The method includes: monitoring group call data in a current cell and obtaining a hyper frame number being a first hyper frame number; when switching from the current cell to a target cell, obtaining the group call data and obtaining an interval range of a hyper frame number of the target cell according to the first hyper frame number, the hyper frame number of the target cell being a second hyper frame number; traversing the second hyper frame number according to the interval range of the second hyper frame number, obtaining a plaintext, and comparing group call session information contained in the plaintext with the group call data of the current cell; and if consistent, decryption by traversing the second hyper frame number being successful, carrying out a decryption operation according to the second hyper frame number.

In some aspects, the techniques described herein relate to a method including: receiving, via a network, a message addressed to a mobile device number (MDN); identifying, by the network, a set of hunt group devices associated with the MDN, the set of hunt group devices including at least a first hunt group device and a second hunt group device; transmitting, by the network, the message to each hunt group device in the set of hunt group devices; receiving, by the network, a reply to the message from the first hunt group device; transmitting, by the network, the reply to a sender of the message; and transmitting, by the network, the reply to at least the second hunt group device.
