Embodiments of this application provide a charging method. The method includes that a session management function determines, a data flow within a protocol data unit, PDU, session and a charging key corresponding to the data flow within the PDU session, wherein a plurality of user plane functions are involved in the PDU session. For each of the plurality of user plane functions, the session management function sends to an online charging system, a quota request for a charging key without available quota for the UPF.

Systems and Methods for telecommunication expense management are provided. A distributed platform including a user support site, multiple user databases and customized user applications is provided to enable organizations to better manage their telecommunication services and expenses. In an embodiment, a method for electronically processing telecommunication invoices includes importing the telecommunication invoices, extracting elements from the imported invoices and performing reasonability tests on the imported invoices. The reasonability test includes conducting an automated comparison against established criteria that may be customized by users. The method includes generating one or more interactive reports that enable an organization to effectively manage its telecommunication services.

The present invention provides systems and methods and apparatuses for enabling private communication between user equipments (UEs) in a (LAN) UE group. The UEs in the (LAN) UE group can communicate with each other using IP and/or non-IP type communication services. The communications between these UEs may take place in the form of point to point (e.g. UE to UE) communication or point to multi-point communication (e.g. UE to multiple UEs) as opposed to UE to Data Network (DN) communication.

A method for providing an online market place for purchasing service from a variety of servers is provided. A GUI or application having a page having a list of carriers for the user to select is sent to a mobile device. A selection of a carrier is received. In response, an encrypted IMSI and Ki are sent to the mobile device. The GUI or application may include other pages for the user to manage service.

A IP telephony service allows customers to form user groups. Each user group can include multiple members, each of whom have their own telephony device. When a member of a user group sends an outgoing communication from one of the telephony devices associated with the user group, the service obtains communication handling instructions for the user group. The outgoing communication is then processed in accordance with the handling instructions. This could include sending copies of the outgoing communication to the telephony devices of other members of the user group. This could also include sending the outgoing communication with an origination identifier associated with the user group, rather than an origination identifier associated with the member's telephony device.

A mobile communication device is provided with a processor. The processor is configured to receive a request for starting a Mobile Originated (MO) service, determine a plurality of remaining usage quotas for the MO service, which correspond to a plurality of subscriber numbers, and select one of the subscriber numbers for starting the MO service according to the remaining usage quotas.
