Definitions

  • Post-paid service the consumer is billed by the end of the month after it has used the services. Such billing scheme is possible with people with credit lines, with which the operator can build long lasting relationships.
  • pre-paid schemes the user buys a service usage allowance amount in advance, and each usage is debited from this credit.
  • Pre-paid is popular with people with no credit lines such as teens, tourists, or foreign citizens. Pre-paid schemes are also popular due to some advantages, including: (a) in many countries, pre-paid phone usage may be had without disclosing personal details, thereby enabling anonymity of the user; and (b) as the customer is not bounded by long term usage agreements, he has the freedom to move between operators, aiming to get the most lucrative plan available at any time.
  • pre-paid billing usage In some markets, for example, Italy, and certain developing countries, as many as 80-90% of mobile customers use pre-paid schemes. In addition, several trends further strengthen the popularity of the pre-paid billing usage: (a) penetration strategies of mobile virtual network operators (MVNOs) are increasingly based on pre-paid users; (b) economic recessions may provide incentives for keeping mobile service, but containing recurring costs; and (c) handset evolution is happening at a faster pace, and post-paid plans with two-year contracts lock customers in to specific devices; however, pre-paid plans allow faster handset replacement cycles.
  • MVNOs mobile virtual network operators
  • pre-paid billing schemes present several challenges to operators.
  • customers are anonymous, operators have a problem developing and managing relationship with them.
  • anonymous customers are also harder to reach. It is also harder transforming those customers into post-paid users.
  • the herein proposed systems and method may enable the user to identify customers along their appearance in the network (even with different identities). This enables the operator to develop marketing relationships with pre-paid customers, further an operator to (a) offer promotions and incentives, (b) understand customer usage patterns (since now the user's different identities are aggregated into a single identity along time, his usage patterns are more accurate), (c) provide better personalized experience, even when the customer resurfaces in the network with new identity, the operator can fetch his profile and provide him with a customized experience (as consumption patterns are known). It will be recognized that the present invention may be used to increase loyalty and higher ARPU of the pre-paid user. This translates later to higher probability that the high ARPU prepaid customer will transform to a post-paid one.
  • the present invention may be used to accurately identify the high ARPU customers. Economical models have shown that it is a better strategy to keep the high ARPU customers, rather than invest in acquiring new customers.
  • the present invention may be used to allow identification of post-paid users when they are using pre-paid accounts. For example, people may buy a pre-paid card when they want to have a specific anonymous usage. Providing benefits in this channel as well, helps strengthening the customer's loyalty to the brand.
  • the present invention may further assist in detection and resolution of identify theft.
  • fraud is not the main purpose of the present system, if an identified number resurfaces with a significantly different usage pattern, the system can point that fact to the operator, to mitigate a risk of fraud.
  • the herein disclosed systems and methods may enable network operators (e.g., a mobile operator) or associated entities (e.g., marketers) to develop marketing relationships with their anonymous pre-paid users, by identifying the customers along their usage of the network even if they are appearing with different identities (MSISDN numbers). This may be done by capturing the customer's unique social, usage habits and/or geographic fingerprints. By this identification, operators can provide customized promotions and personalized services, increasing ARPU and loyalty in the competitive pre-paid market.

  • the Social Network Analysis also referred to by the acronym SNA
  • SNA Social Network Analysis
  • the system builds a network representing the social group of the user.
  • Each node in this network represents a user, and nodes are connected by weighted edges if the people the nodes represent are communicating via some mobile channel. The more two people are communicating (like more calls or more SMSs), the weight of the edge connecting them in the network is larger.
  • weights may have decay functions that govern the decreasing of the weight along time automatically according to some function. Thus, occasional, erroneous or limited scope communication between individuals is not captured in the network (and in the fingerprint).
  • hubs, or popular nodes that are common to many people's peer group may be filtered out from the graph.
  • the intention is to have a graph with neighborhoods (the nodes connected to each node representing the people the person is in contact with on a regular basis) as unique to each customer as possible.
  • the degree of the neighborhood for a specific node is extended.
  • the fingerprint may be representing not just the direct peers, but also the peers of the peers (second degree neighborhood) to find differentiating patterns.
  • the SNA is maintained along time, to capture the evolving social worlds of the customer.
  • Usage habits fingerprints may be used, according to an embodiment of the invention, in situations where the user cannot be identified based solely on his social fingerprint, even though it may be used in other situations as well.
  • the system will include information about his usage habits to try and make his signature unique.
  • Usage habits patterns may be collected, according to an embodiment of the invention, from value added services (VAS services), and include statistics on how the user is using VAS services such as MMS, SMS, WAP, Mobile Internet etc.
  • VAS services value added services
  • Examples for such statistics for a cellular network scenario may include: (a) consumption distribution of different services (percentage of SMS in the VAS usage, of MMS, etc.); (b) time and week day usage distribution; (c) web content types (interests as hinted by the web pages the user is browsing); (d) time to reach percentage of consumption (namely, how much time it takes the user to consume 80% of his balance); (e) pre-paid indicators such as time interval between top-ups, sum of typical top-up, etc.
  • the usage habits may be a principal indicator, or they may be used secondarily to supplement or confirm one ore more other principal indicators, e.g., to confirm or deny an identification based on the social network.
  • the BTS the station that the handset communicated with
  • the system can capture a distribution of where a person usually makes his calls form (ride home, office, house, gym etc.). This geographical pattern is used to further differentiate between several otherwise common identities.
  • the Geographic Information from the voice service may be used.
  • the geographic usage may be a principal indicator or one of a number of principal indicators.
  • coactivity may be used an additional measure to differentiate between identities. That is, if two nodes are considered to be the same person based on all other facets, then having those two nodes active in the same time may hint that they are two separate identities and the two will be maintain in the system as such. This is mainly important at the initial phase of a new identity which for a limited period of time resembles an existing identity. Coactivity may enable managing them as two separate identities earlier.
  • Figure 3 illustrates a state machine which may be implemented either by a system or as a method, for identifying users of a network, according to an embodiment of the invention.
  • a number (or other user identifier) is used for connecting of a user to network resources
  • the system tries to see if it is a new number (e.g. MSISDN). If it is identified as a known active number, it is going through a filtering phase to decide if it belongs to a black list.
  • a black list may include known identities that have been deemed as inappropriate for long term relationships (tourists, foreign workers, people with high complaint rate with customer care, people with poor credit risks, other forms of financial or operational risk, etc.).
  • the system may permit an administrator (or administrator software) to browse this list from time to time and reconsider the status of selected blocked numbers (for example, if marketing policy has changed).
  • the number is not an active one, it is moved for the identification phase. Since it is new in the system, one can assume that not enough information is available to construct a fingerprint and make a decision about its identity. Thus, the number stays in the accumulation state until the user has made enough usage of the network so a pattern is emerging. From time to time, the system tries to use the collected information to build a fingerprint that will identify the user. Once it succeeds, the system first checks the black list to see if the identity is not blocked (in case the leading identity the new number has been associated with), and if applicable, manages the number as an identified identity.
  • Figure 4 illustrates a system for user identification, according to an embodiment of the invention.
  • the proposed system may include some or all of the following main components (as well as possibly additional components).
  • the Social Network Analysis (SNA) engine is responsible for building and maintaining the social fingerprint of the user.
  • the Customer Experience Management (CEM) engine is responsible for capturing the usage patterns of the customer while using services.
  • the Location Engine is responsible for building the geographic usage distribution of the calls the user is making.
  • the Identity Engine manages the identity of customers. It has association between a main identity (e.g. general unique code or MSISDN) and all the MSISDN' s associated with this specific user.
  • the identity engine gets its information from the SNA, CEM and Location engines.
  • the Customer Browser is an application that allows the operator to browse the identities in the identify engine data base. Using query and filtering the user can digest a specific customer population viable for a promotion.
  • Pre-Paid management this would be necessary to get pre-paid usage information (top-up date and time, amount etc), and to update MSISDN profiles (for example, if some benefit is to be given to the customer).
  • Billing systems - part of the benefits of the system is to make focused campaigns, thus integration with the billing system to update prices and rates is necessary. Further, the billing system may act as a source for the CEM system to build the profile of the user.
  • the herein disclosed methods and systems may supports one or both of the followings modes of operation - batch and real time.
  • Fig. 5 depicts an example use case of batch mode.
  • the system allows the operator to generate timely identification lists of Identities based on specific attributes. For example, the operator can ask the identity server to provide all customers with specific attributes like average ARPU or activity in the network for some consecutive period of time.

Abstract

La présente invention concerne un procédé et un système destinés à déterminer l’identité d’un utilisateur sur un réseau qui autrement ne permet pas d’identifier l’utilisateur en tant que tel, par exemple, un utilisateur de téléphone mobile prépayé. Selon un mode de réalisation de l’invention, une pluralité de profils d’utilisateur peuvent être constitués, en fonction de la consommation de communications sur le réseau, et pour les nouveaux utilisateurs, un profil d’utilisation peut être constitué et comparé aux profils d’utilisateur précédemment constitués. En fonction du degré de similitude, on peut déterminer que cet utilisateur correspond à un utilisateur ayant précédemment utilisé le système. Différents profils d’utilisation peuvent être utilisés, comprenant, par exemple, réseau social, utilisation géographique, activité de compte, etc.
