The present invention discloses methods and systems for communicating at a cellular router between a first wireless communication module and a first subscriber identity module (SIM). The cellular router receives a first request from a first wireless communication module and encapsulates the first request in a first modified request. The cellular router then sends the first modified request to a first SIM card in a first communication apparatus and waits for a first modified reply. While waiting for the first modified reply the cellular router sends at least one halt message to the first wireless communication module after a first time threshold. After receiving the first modified reply, the cellular router decapsulates the first modified reply to retrieve a first reply and sends the first reply to the first wireless communication module where the first modified reply is a reply to the first modified request.

A method (and structure) to connect a mobile device to a local Wi-Fi network includes providing an input capability for a user of the mobile device to request to make a connection to a local Wi-Fi network. A processor on the mobile device retrieves, from a memory device of the mobile device, a listing of registered local Wi-Fi networks available at the user's current location. A request to connect to a selected one of the registered local Wi-Fi networks listed on the retrieved listing of registered local Wi-Fi networks is transmitted from the mobile device. The mobile device is connected to the selected registered local Wi-Fi network upon receipt of an indication by the selected registered local Wi-Fi network that the user has been validated and verified as trustable.

A charging method, apparatus and system are provided. The charging method includes: receiving a first request message from a Network Function (NF), wherein the first request message carries following information: first Quality of Service (QoS) information; or second QoS information; or second QoS information and updated first QoS information; the first QoS information comprises requested QoS information or negotiated QoS information; and the second QoS information comprises QoS information actually used after the NF sends a previous first request message; and performing charging according to the QoS information carried in the first request message.

The present application generally relates to wireless communication technology. More particularly, the present application relates to a method and an for handling Background Data Transfer (BDT) for a User Equipment (UE). The present application also relates to computer program product adapted for the same purpose. According to one embodiment, a method for handling Background Data Transfer (BDT) for a User Equipment (UE) comprises: a) transmitting, from a node for Application Function (AF) to a node for Policy Control Function (PCF), a policy request indicating the BDT is UE trajectory-relevant; and b) at the node for AF, receiving from the node for PCF, a plurality of BDT policy groups, each of which is associated with a corresponding section of a trajectory.

A method for managing a charging operation in a communication network is disclosed. The method comprises receiving a content specification identifying content, vendors and a condition relating to charging the vendors for provision of the content to a UE. The method further comprises creating a charging policy for provision of the content, which specifies division of charging for provision of the content to a UE between the vendors in accordance with the condition, receiving, from a UE, a request for provision of content over the network and retrieving a charging policy corresponding to the requested content. The method further comprises creating a charging entry for provision of the requested content, the charging entry dividing charging for provision of the requested content between vendors identified in the retrieved charging policy and a subscriber account associated with the UE in accordance with the retrieved policy.
