The present invention relates to communication network, and particularly to a method and device for establishing, monitoring/controlling a service connection in a wireless communication network.
As 3GPP LTE mobile broadband technology is getting matured, it makes possible for end user to conveniently access/download applications via mobile handset anytime, anywhere and in any way. More and more application providers dig out this business opportunity, attract huge mobile end users via providing a lot of fancy applications. However, with LTE mobile broadband deployment, most network operators are also worrying about only becoming as network “bit pipe” providers, and are facing challenges how to earn money from the application service.
The new emerging sponsored data connection business model occurs between network operator and third party application provider. In such new business model, the sponsored application service provider will own the users, who will pay, for the service in their use, the application store provider (such as Google, Apple AppStore, Yahoo, Facebook, instead of paying directly, for the service in their use, the mobile operator. The sponsored application service provider will have further revenue sharing with the network providers to guarantee the quality of service (QoS) of its application via mobile operator's broadband network.
Currently, mobile operators have the ability of 3GPP policy and charging control (PCC) and deep packet inspection (DPI) technology to assist operator in controlling and managing the network bandwidth to make full use of and monetize the resource in the their network. However, the current 3GPP architecture cannot well adapt for the new emerging sponsored business model between mobile operators and third party application store (AppStore) providers. The 3GPP PCC architecture only provides the solution for operator to control its own subscriber's data service connection, but does not propose how to have policy and charging control for the end user owned by the third party application providers, since the third party end user pays for the network connectivity which is separate from the subscriber's online charging in the PCC architecture.
Thus, in a sponsored application connection service model, there is short of a solution enabling the operator dynamically control/configure data connection of the sponsored application service during the existence of the connection, according to traffic flow of data connection of the service.
In view of the drawback existing in the prior art, the present invention provides a method and device for establishing and maintaining the connection of sponsored service in the communication network, thereby solving the inability of dynamic metering of traffic flow for the service of the UE in the data bearing network of the prior art, and in correspondence to requirement of traffic flow of the service connection, dynamically controlling, configuring the data connection of the sponsored application service to dynamically meet the demands of QoS control service in combination with the usage limit for the service of UE, thus enhancing the performance of current 3GPP PCC architecture so as to enable policy and charging control for the sponsored data service or application in the operator’ network.
According to one embodiment of the present invention, there is provided a method for processing a service connection in a communication network, comprising: A) determining, in response to an establishment request for the service connection from a UE, whether the service corresponding to the establishment request is a sponsored service, wherein the sponsored service is provided by a third party application provider; B) sending a validating request for a sponsored service to the third party application provider, if the service corresponding to the establishment request is the sponsored service; and C) controlling the sponsored service connection according to the information related to the sponsored service, if receiving a successful acknowledgement corresponding to the validating request; wherein the related information is acquired from the third party application provider.
Optionally, the implementation of the method may be deployed in the subscriber profile repository (SPR) of the communication network.
Correspondingly, according to another one embodiment of the present invention, there is provided a method of providing service usage information of a UE in a service management and usage control system of a communication network, comprising the steps of: receiving usage report of a third party service on the UE; b) judging, according to the report, whether the usage limit of the third party service for the UE is exceeded; c) sending a limit exceeding report, if the usage limit of the service is exceeded.
According to another one embodiment of the present invention, there is provided a device for processing a service connection communication network, comprising: a connection determining module for determining, in response to a establishment request for the service connection from a UE, whether the service corresponding to the establishment request is a sponsored service, wherein the sponsored service is provided by a third party application provider; a validating request sending module for sending a validating request for the sponsored service to the third party application provider, if the service corresponding to the establishment request is a sponsored service; and a connection establishing module for controlling the sponsored service connection according to the information related to the sponsored service, if receiving a successful acknowledgement corresponding to the validating request; wherein the related information is acquired from the third party application provider.
Accordingly, according to still another one embodiment of the present invention, there is provided a device for providing service usage information of a UE in a service management and usage control system of a communication network, comprising: a service report receiving module for receiving usage report of the service on the UE/end user; a limit judging module for judging, according to the report, whether the usage limit of the service for the UE/end user is exceeded; a limit exceeding report sending module for sending a limit exceeding report, if the usage limit of the service for the UE/end user is exceeded.
In the solution of embodiment(s) of the present invention, it is SPR that interfaces with the sponsored application service provider, to acquire the runtime information of sponsored service connection, for example, QoS information. Being well compatible with the charging architecture of the existing 3GPP standard, there is no need of improvements for the interfaces of Gx and Gy. The solution of the embodiment(s) renders application layer transparent to the network bearing layer, thereby enabling the network bearing layer to acquire, in real time mode, the usage status, usage/spending limit of the sponsored service connection and QoS related information etc., thus resulting in a more precise charging. Moreover, the network bearing layer does not need to adapt particularly for the sponsored service connection.
Furthermore, for the requirement of data traffic flow of the sponsored service connection, policy and rule of such as charging are dynamically generated, thereby enabling a dynamical control, configuration of the data connection of the sponsored application service, thus dynamically meeting the requirement of QoS control service.
Additionally, in one embodiment of the present invention, with the utilization of position of SPR in the PCC architecture, data service is connected between a first UE and a second UE and the sponsored service is controlled in runtime mode, thereby making full use of the existing architecture of PCC, minimizing the amendments to the system. Moreover, SPR further queries the usage control and charging system of third party application provider to verify the validation of end user, the sponsored service connection to which the UE requests the attachment and the data usage relative thereto. On the basis of an authorized data usage, in some embodiment (s) of the present invention, policy and charging control rule is generated according to the information about such sponsored service connection, moreover, generally, the embodiment of the present invention corresponds to basic 3GPP PCC architecture and principle.
In one embodiment of the present invention, charging data record may be generated, thereby facilitating offline charging settlement among relevant parties.
