Charging method and apparatus for proximity-based service

摘要

A charging method for Proximity-based Service (ProSe) used in a first user equipment (UE) of a wireless communication system is disclosed. The charging method includes: establishing a ProSe service with a second UE; generating charging information for the ProSe service according to collected transmission information, wherein the ProSe service is between the first UE and a second UE in proximity and comprises ProSe discovery, ProSe communication or both, and wherein the transmission information comprises at least one of: radio resources dedicated for the ProSe service, allocated to the first UE by the a base station of the wireless communication system; at least one traffic volume report corresponding to uplink or downlink data volume, transmitted to the base station; and a time-elapsed duration for the ProSe service; and transmitting the charging information for the ProSe service to the base station or a core network entity of the wireless communication system.

主权项

1. A charging method for proximity-based Service (ProSe), wherein the charging method is used in a mobility management entity (MME) of a wireless communication system, the method comprising:
allocating an evolved packet system (EPS) bearer identity (ID) dedicated for a ProSe service established by a first user equipment (UE) for communicating with a second UE and/or indicating charging characteristics associated with the ProSe service between the first UE and the second UE in a Create Session Request message which is to be transmitted to a packet data network gateway (PGW) through a serving gateway (SGW), when a dedicated EPS bearer is activated for the ProSe service or when a dedicated PDN connection is created for the ProSe service; receiving a Create Session Response message including a charging ID from the PGW through the SGW; and transmitting at least one of the dedicated EPS bearer ID, the associated charging characteristics, and a charging ID to at least one evolved Node B (eNB) serving the first UE and the second UE.
