## Background
CROSS REFERENCE TO RELATED DOCUMENTS
This application claims priority under 35 U.S.C. §119 to Indian Patent Application Serial No. 1424/CHE/2006 of SATHYAN et al., entitled “BUSINESS CASE EVALUATION SYSTEM AND METHODS THEREOF,” filed Aug. 9, 2006, the entire disclosure of which is hereby incorporated by reference herein.
BACKGROUND OF THE INVENTION
1. Field of the Invention
The present technique relates generally to an architecture reference model for wireless network designs. In particular, the present technique may be the evaluation of the service space and the network space as one full flow that may be required to bring out business-focused technology development.
2. Discussion of the Background
Network design reference models such as I-centric and WWRF/WSI have “service-deployers” as a point of focus that enables them to evaluate market penetration as well as other user-related capabilities of applications or services. However, the said reference models do not focus on the evaluation of an end to end flow from services to network capabilities. Furthermore, the said reference models evaluation techniques may have been able to satisfy past requirements primarily due clearly defined roles like network providers providing network elements, service providers determine the services offered, integrators determine the implementation of service to network, etc.
Moreover, as and when the “service deployers” have the network capability to enable particular application functionality, the right products may not be readily available. Furthermore, the network developers make development in their network, without having an end to end view available, resulting in products with sub-optimal market fit. As a result, profitability of the network developers as well as rapid service development may be affected.
Accordingly, there is a need for a technique that evaluates user space and network space as one full flow that may be required to bring out business focused technology development. However, converged networks may be set to change dramatically with a multitude of service providers, content providers, network providers and equipment providers having to rapidly conceptualize, evaluate and integrate their service offerings. Furthermore, due to increasing competition, there may be additional pressure to deliver the right product or service on time and every time.

Referring now to the drawings, wherein like reference numerals designate identical or corresponding parts throughout the several views, and more particularly to FIGS. 1-2 thereof, which will be used to illustrate a method and system for modeling and designing a network functionality, according to exemplary embodiments of the present invention.
The following description is full and informative description of the best method and system presently contemplated for carrying out the present invention which is known to the inventors at the time of filing the patent application. Of course, many modifications and adaptations will be apparent to those skilled in the relevant arts in view of the following description in view of the accompanying drawings and the appended claims. While the system and method described herein are provided with a certain degree of specificity, the present technique may be implemented with either greater or lesser specificity, depending on the needs of the user. Further, some of the features of the present technique may be used to advantage without the corresponding use of other features described in the following paragraphs. As such, the present description should be considered as merely illustrative of the principles of the present technique and not in limitation thereof, since the present technique is defined solely by the claims.
The present invention relates to an architecture reference model for wireless network designs. In particular, the present technique may be the evaluation of the service space and the network space as one full flow that may be required to bring out business-focused technology development.
FIG. 1 is a flow diagram illustrating a design process indicative for modeling and designing a network functionality, in accordance with an aspect of the present technique.
As will be appreciated by people skilled in the art, to best understand the present invention it is important to be familiar with the environment in which it is used and the basic terminologies. The design process is a series of steps followed by designers, architects and some system designers. The typical stages of the design process includes design brief (a statement of the task at hand), analysis (analysis of the current system), research (investigating similar products in the field or related topics), specification (detailed definitions of what exactly the product must do), design (presentation of solutions), development (continuation and improvement of one solution), testing (testing of the system), implementation (introducing the design into the environment), evaluation (evaluation of process) and conclusion (summary of process and future suggestions). Modeling may be an abstract representation of an object or system from a particular viewpoint. Designing may be a process of originating and developing a plan for a new object. Moreover, designing normally requires considering aesthetic, functional, and many other aspects of an object, which usually requires considerable research, thought, modeling, iterative adjustment, and re-design. The network functionality may be a characteristic that causes a good or service to have a value to potential customer dependent on the number of customers already owning that good or using that service.
The method starts at step 102, wherein the design module may be identified. The method continues at step 104, wherein the layer in the chromatographic (chromatography is used to determine the identity and concentration of components in a particular layer) model where the design module may be suitably fit. By way of example, in this case, the model may be such as a network service or a platform enhancement. The method continues at step 105, wherein the cost and values of the business case may be identified in the current layer. It should be noted that when step 105, may be true the method at step 118 may be executed else when the step 105 may be false, the method at step 104 may be repeated. The method continues at step 106, wherein the presence of the preceding layers may be determined. The method continues at step 108, wherein the presence of the succeeding layers may be determined. It is to be observed that when the step 106 is true the method continues with the step 110 and when the step 106 is false the method continues with the step 118. It is also to be observed that when the step 108 is true the method continues with the step 112 and when the step 108 is false the method continues with the step 118. The method continues at step 110, wherein the layers are incremented and may be the preceding layers for the current layer. The method continues at step 112, wherein the layers are decremented and may be the succeeding layers for the current layer. In these cases, the impact of the design module may be identified and the components required for implementation in each layer may be identified.
Furthermore, the method continues at step 114, wherein the value of the components may be identified for each layer. It is to be noted that at each layer inputs may be received that needs to be plugged into the end to end business case evaluation. The method continues at step 116, wherein the value of the components may be identified for each layer. It is to be noted that at each layer inputs may be received that needs to be plugged into the end to end business case evaluation. The method continues at step 118, the end to end business case may be evaluated. It should be noted that the spreading impact of the design module may be similar to the process of chromatography. Chromatography is a concept where the components filter themselves as they spread. In addition, the design module may be anything from a generic service such as control of home appliances using wireless network or a protocol to support a new service in the wireless environments.
By way of examples, the below section depicts specific use cases for the chromatographic design process. In addition, the below section details the two use cases related to the wireless design concepts and also explains the process of using the chromatographic model to validate the case for the design concept. The below mentioned both cases explain the values added to the preceding layers and requirements in the succeeding layers which can be used to validate the end to end business case and then reject or accept the concept.
The first design module that may be mentioned may be a wireless video conferencing service. The features of the design module may be such as seamless video conferencing across mobile phones, personal computers (PCs) and specialized video conferencing (VC) equipment. In this case, customizable presentation layer based on device handling the service may be utilized. In addition, capability to chat with other users, as well as to share a common whiteboard.
In one embodiment, to depict on functional description, wireless video conferencing service (WVCS) may be a component in the user service layer (explained below). In another embodiment, in addition, using the design process the value (benefits) of the component in the user experienced layer (explained below) may be identified. To be clear of the sample components that may be identified such as personal face to face communication, remote education opportunities, remote medical assistance, cost effective business discussions or visual entertainment. Each of the said need may be evaluated individually to derive inputs for the end to end business case.
In another embodiment, the requirements (costs) from the succeeding layers for implementing the said component may be identified. In another embodiment, at the adaptation layer (explained below), a mediation component for translating present data based on the user device and the network may be needed. In another embodiment, in the network service layer (explained below) components such as video or audio compression, internet protocol (IP) streaming and presence services may be required. In another embodiment, in the protocol or interoperability layer, components such as cluster capability and H.323 protocol support may be required.
In yet another embodiment, in the platform layer, components such as high availability, real-time, fault-tolerant, scalable multi-card architecture may be required. In addition, once the said components may be defined, inputs on the costs associated may be extracted and fed into the end to end business case evaluation.
Furthermore, the second design concept that may be mentioned below may be a low level network service enhancement. The features may be current wireless protocols (MAP) does not support delivery of the calling name (CN) as signaling information to the mobile. In addition, the design concept may be to modify existing MAP/SS7 to add the CN to the signaling data transmitted to the mobile. The term mobile application part (MAP) may be defined as a global system for mobile communications (GSM) protocol to provide an application layer for the various nodes in the core mobile network to communicate with each other in order to provide services to mobile phone users.
To depict on the functional description, in one embodiment, in the network service layer may be the wireless calling name (WCNAM) component maybe required. In another embodiment, in the adaptation layer there may be no values. In addition, a cost input may be considered for requirements. In another embodiment, in the user service layer, components such as named based call barring, named based ring tones may be required. In another embodiment, in the user experience layer, components such as enhanced security against prank calls, quicker recognition of caller may be required. In another embodiment, at the lower layers, in the protocol layer, components such as update MAP/CAMEL specs, enable LIDB functionality, backward compatibility to earlier MAP/CAMEL specs may be required. In yet another embodiment, in the platform layer, there may be no additional component for a change may be identified for the requirements. In this case, a similar exercise of input collation may be done from the said components and fed into the end to end business case evaluation. The term customized applications for mobile networks enhanced logic (CAMEL) may be defined as a set of GSM standards designed to work on a GSM core network. These standards allow an operator to define services over and above standard GSM services. The CAMEL architecture is based on intelligent network (IN) standards, and uses the CAP protocol.
FIG. 2 is a schematic diagram 200 illustrating an architecture consisting of multiple layers that are involved in offering one or more experiences to an end user or a customer. The schematic diagram 200 consists of one or more layers built as preceding layers and succeeding layers. The preceding layers and the succeeding layers comprise a user experience layer 216, a user service layer 214, an adaptation layer 212, a network service layer 210, a protocol layer 208, a platform layer 206 and a monitor and control layer 204. It should be noted that based on the identified current layers the above one or more layers of the current layer may be the preceding layers and the below one or more layers of the current layer may be the succeeding layers. The said layers may be explained in detail in the following sections. It should be noted that, for any experience to be delivered to a user, one or more components in each layer may be involved. In addition, there may also be components in different layers such as “owned” or controlled by disparate stakeholders. By way of example, the user service layer components may typically be controlled by the service provider. This integration of various stakeholder components may be a key element of the model. The first set of components may be the components that may be controlled by the service providers. The second set of components may be the components that may be controlled by the network providers. The third set of components may be the components the integrated components of various stakeholders or customers.
Furthermore, the said layers may be segregated into first type user centric such as user experience and user service layers. In addition, as a second type network centric the layers may be segregated such as network service, protocol and platform layers. It is noted that as a rule of thumb, most components in the network centric may be owned by the network provider and components in the user centric layers may be owned by the service or content providers. In addition, the adaptation layer may contain components that mediate, transform and facilitate operations between the user and the network centric layers. It is to be observed that one of the key terminologies that may be used in the model description is that of a design concept (DC). In addition, this is an abstraction to describe the feature/service/enhancement that may be the subject of evaluation using the model.
In one embodiment, the user experience layer 216 may be the outmost layer of the model and the components in this layer 216 concern themselves with the experimental changes that a user may obtain with a specific design concept. Furthermore, components in this layer 216 may be required to describe in technology and network agnostic terms and may typically describe the emotional needs that may be satisfied or being attempted to be satisfied.
By way of examples, components that fit into this layer 216 may be security, social interaction and control. Any of these may be utilized and expanded to enable further clarity. In addition, wireless buddy finder application may be sought to be deployed to address the primary need of users to increase “interaction vocally with friends”. Hence from a business case perspective, what need to be evaluated in this layer may be things such as “how much would a person pay for this component”. In this case, the users also have security needs and may be giving his location available online that may give him an experience of “lack of privacy”. The said component may also require needs to be an input for the evaluation of the design module.
In another embodiment, the components of the user service layer 214 may describe specific user services that may be offered by the service provider. In addition, the said layer 214 may further describe the service in terms of the functionalities, limitations, as well as interactions with other services. In this case, depending on the granularity and specificity of the service, component definitions may be network agnostic or network aware.
By way of example, components in the user service layer 214 may be wireless video conferencing, push to talk. In addition, the said components as well as buddy finder application described in the previous section are examples of user service layer 214 components. In addition, components in this layer 214 may be used to offer multiple and diverse user experience components. Furthermore, push to talk application may satisfy a communication between friends experience in a retail user scenario, it may also satisfy a control over team experience in an enterprise scenario. In addition, all said needs to be inputs into an end to end evaluation.
In yet another embodiment, the adaptation layer 212 may be a transition layer between the user space and the network space. In addition the said layer 212 may be an optional layer in the evaluation of any specific design concept and may be formulated primarily as a “good to have” design practice. The said layer may consist of components that may define mapping and data transformations between network-defined services and their usage to implement user service components.
Furthermore, apart from a clean and segregated design, this allow the user service components to remain network-agnostic and potentially increasing the reach and target audience of the design concept. Furthermore, the said buddy finder application may find buddies across WLAN, GSM and possibly the regular wired internet domains, using different mediation components. In addition, introducing components in this layer 212 may also add an element of future-proofing to the user service layer components. In addition, a user service component that may provide push to talk services in a GSM network may continue offering the services even if the network migrates to UMTS.
In an embodiment, the network service layer 208 may contain components that may expose services offered by the network. These components may be network and technology aware components. Defining and evaluating these components requires a high level of technology competence and may typically involve technical architects. In addition, components in this layer may define the service, the protocols and access mechanism that can be used to access the service and the technology capabilities required from the layer below the interoperability layer 208.
By way of example, components in this layer may be internet protocol (IP) streaming, intelligent networks (IN) capabilities, mobility management. To take a specific example, the IP streaming component in this layer 208 may be used by multiple user service layer 214 components such as wireless video conferencing. The user service layer 214 components may likely use multiple network service layer 208 components specifically wireless video conferencing. In addition mobility management may also be used for the said purpose.
In another embodiment, components in the interoperability or protocol layer 206 address the aspects of implementing a specific network service with a measure of platform independence. In addition components in this layer expose application programming interfaces (APIs) or protocols for accessing platform functionality such connectivity such as sockets, messaging, XML interface, executing environment.
By way of example, components such as POSIX standard, the java virtual machine (JVM), the SNMP API may be specific examples. In all cases, the said components may allow a network service to be created in a relatively platform independent manner.
In another embodiment, components in the platform layer 204 may provide basic platform level functionality examples of which are mentioned in the earlier section as well. In addition functionalities such as memory management, fail over, hot swapping, inter-process communications may come into scope in this layer 204.
By way of example, the utility of the whole model may be seen clearly with a specific example of a new design concept in this layer. To mention specific examples, a network designer comes up with a new design concept related to high availability (HA). In addition, instead of evaluating the product on technical merits, by using the model, the designer may be forced to identify and evaluate components at all the other levels and present an overall case for the development of the design concept.
In yet another embodiment, the monitoring and control layer 202 components may tie up the management information across components in one or more layers. In addition, there may be advantages of pulling out as a separate aspect that span across the other one or more layers. Firstly, the said layer 202 enables the thought process to incorporate concepts of integrated management of the whole service offering. To be more specific, in a lot of cases, the said layer 202 also helps in clarifying and improving the design concept itself. All of the main management functionalities such as fault configuration, accounting, performance and security need to be considered while detailing aspect of the model.
As will be appreciated by a person skilled in the art, the various implementations of the present technique provide a variety of advantages. For example, the present technique may be an end to end approach to the modeling and design of network functionality. In addition, in the rapidly changing converged wireless network, this model may be significant for the below stated reasons the advantages may be summarized as below. Firstly, the chromatographic model fosters an end to end evaluation mindset and may help businesses and stakeholders in doing a detailed analysis before implementation of specific design concepts. Secondly, in a market where competition may be very high and there may be no margin for error in terms of product selections and service offerings, the model with its simple but effective methodology may yield significant business benefits. Thirdly, a detailed analysis of each of the layers for a particular design concept leads to a full architecture explanation and help in defining clearly the depth and breadth of the service offering. Fourthly, the model brings together the various stakeholders on to a common evaluation platform, and enables them to think along similar lines.
