Marketing & Advertising – Campañas de Mobile Marketing y Clientes basadas en la ubicación

Los anunciantes quieren (y es lógico que así sea) poder dirigirse a los consumidores con anuncios, campañas y publicidad en general entendiendo el contexto del individuo objetivo. Dentro del contexto del consumidor, la localización precisa se considera un elemento esencial y muy importante a ser tenido en cuenta. A través de varios estudios, esto ha demostrado aumentar la eficacia de las campañas en un 86% e impulsar mayores tasas de respuesta. Además, también se estima una mejora entre 5(cinco) y 7(siete) veces de take-up de las ofertas presentadas.

Entre las mejores prácticas destacamos la inclusión de Call-to-action medibles, como así también vouchers y códigos QR.

 Este tipo de campañas traen asociados importantes beneficios entre los que se destacan:

  • Mejora de la orientación y eficacia de las campañas sobre móviles
  • Registra el comportamiento histórico y detecta patrones para la previsión de futuras campañas
  • Permiten las Call-to-Action en tiempo real para impulsar la participación
  • En comercios minoristas permite acción inmediata mediante conocimiento preciso de la ubicación

Para poder implementar acciones y campañas de este tipo es necesario contar con una plataforma de ubicación (LBS) que se integra a las diferentes plataformas de publicidad a través de API flexibles.

Mature, responsible individuals flourish within this environment, and are encouraged to be open and honest, to seek support and feedback at all times. There is a reasonable amount of documentation – of policies, best practice etc – and these need to be understood and observed. However, the nature of the business means that discretionary judgements are required frequently – and the individual will be encouraged to take on responsibility/autonomy within this context.

Impact

This is a significant role within the company. The speed of delivery of a solution to our customer’s requirements and its subsequent stability and performance can be greatly affected by the role holder. It is a customer facing role, and much of the assessment of the capability of CS by the customer will be based on the level of professionalism demonstrated by the role holder. This is essential for the retention of customers and securing future business from them.

Additional Information

For some projects, a degree of security clearance may be required (up to SC) and candidates must be willing to apply for such clearance with Creativity Software.

What are Location-based Services (LBS)?

These enable mobile operators, law enforcement agencies and the banking sector to capitalise on the incredible value of mobile location intelligence.
Location-based technologies offer MNOs the opportunity to deliver contextual services. As such services are specifically orientated towards the position of the mobile handset, it enables MNOs to provide services that are more targeted and effective.

Location Based Applications and Services

Location services cover a wide range of services, orientated at individual users or devices and vehicles. These can include:

  • Fraud mitigation services for the card payment industry
  • “Find Me” services e.g. nearest restaurant, coffee bar, ATM etc
  • Location-based charging, for example ‘Home Zone’ or ‘Office Zone’
  • Retail offers – dependant on user proximity
  • Social networking services
  • Visitor local information services
  • Child find/locate services
  • Route planning/navigation
  • “Where am I” type information services
  • Location-based games
  • Vehicle and asset tracking
  • Support for emergency services and Law Enforcement Agencies.

Such applications may be supported within a mobile operator’s network, or externally via third parties. In both cases, the application which depends on information obtained and processed by network resources is referred to as an LCS Client.

Location Techniques

The location of the UE is defined in terms of latitude and longitude coordinates. The accuracy depends on the particular technique used to locate the mobile. Several mobile industry variants are currently deployed – GSM, UMTS, LTE 5G & CDMA. The method for ‘requesting’ a user’s mobile location and the resultant network generated messages are standardised, regardless of the location technique utilised.
The ability of a mobile network to establish the location of UE is essential to ensure incoming calls are ‘directed’ to the appropriate cluster or group of cells. Such clusters or groups are defined/known as Location Areas. To ensure consistent call management, mobiles continually assess and measure the radio parameters from surrounding / neighbouring cells and detect when moving from one cell area (LAC) to another, in close co-ordination with the radio access network and base station infrastructure. Using this information, it is possible to ‘triangulate’ the geographic position of a user mobile. There are three primary data sets that can be used to cost-effectively locate the position of UE equipment without significant overhead. These are:

  • Cell ID
  • Cell ID + Timing Advance (TA) (CITA)
  • Cell ID + TA + Relative Signal Strength (RxLEV) (CITARx)

Infrastructure Required

In order to capture the information required for determining the location of UE and to control the management of authorised requests from LCS client applications to access the data requires the deployment of two dedicated nodes in mobile networks: the Gateway Mobile Location Centre (GMLC) and the Serving Mobile Location Centre (SMLC).

What is a GMLC?

Creativity Software’s GMLC solution can interconnect with third party SMLCs or can be delivered as part of a complete turnkey solution. Our GMLC offers a range of deployment options, supports connectivity to the NSS via Lg and Lh interfaces or alternatively make use of the MAP ATI function. For IN environments, Push Mode location updates can be supported.

GMLC – How it works

Privacy is a critical issue in location based services. The Creativity Software GMLC performs authentication and authorisation checks in location requests received from the LCS to ensure privacy and adherence to permission policies.

The GMLC provides the interface to the LCS client which may be positioned external to the network e.g. 3rd party VAS application. The GMLC receives individual requests to locate and report back the geographic position of a user mobile. Such requests are in general permission-based reports – i.e. the particular mobile user has granted approval for his/her location to be made available. At the same time, checks are made to confirm that the LCS client is authorized to make such a request and ensure the UE (User Equipment) is able to support LCS enquires.

The GMLC must first determine which Serving Mobile Switching Centre (MSC) is managing the UE at the time the LCS request is made. To do this, it first identifies the MSC involved by making a request to the HLR. The HLR returns this information and a message is sent to the appropriate BSS via the MSC. The BSS determines the serving Cell ID and if available the timing and signal strengths from this and neighbouring cells.

This combined information is routed to the SMLC / SAS / E-SMLC where the calculation of geographic position estimation is carried out. The result is passed back to the MSC via the radio sub system and then to the GMLC for delivery to the LCS client (according to the 3GPP standards, there is no direct connection between the SMLC/SAS/E-SMLC and the GMLC – the location is always reported back to the MSC that has initiated the location request).
The GMLC is based on industry-standard SS7 protocol stacks, supporting SIGTRAN interfaces for IP connectivity and TDM transport in legacy environments. Creativity Software’s GMLC can interconnect with third party SMLCs, or both can be provided as part of a turnkey solution. Creativity Software’s GMLC solution can also be configured as a fully standards-compliant MPC for CDMA networks.
The interface provided complies with OMA MLP V3.2 and V3.1. Priority levels are handled through the optional selection of a priority level within the request and feeding appropriate prioritised queues. All the following messages flows are supported as per OMA:

  • SLIS (Standard Location Immediate Service)
  • ELIS (Emergency Immediate Service)
  • TLRS (triggered location reporting service)

If available, following subscriber information can be provided to the LCS-Client in addition to location response:

  • Subscriber state
  • Age of location
  • IMSI
  • IMEI
  • MCC,MNC,LAC,TAC
  • VLR address

Our GMLC can interface with any HLR/MSC/SGSN that supports 3GPP 29.002.
According to the 3GPP LCS architecture, the interface between GMLC and HLR is known as the Lh interface, and the interface between GMLC and MSC/SGSN is known as the Lg interface. The GMLC uses the Lh interface to obtain routing information of a target terminal. It uses the Lg interface to request the positioning information of a target terminal from the radio network via the core network.

The GMLC supports the following MAP LCS standard messages:

  • MAP-SendRoutingInfoforLCS (SRI-LCS)
  • MAP-ProvideSubscriberLocation (PSL)
  • MAP-AnyTimeInterrogation(ATI)
  • MAP-SubscriberLocationReport (SRI)
  • MAP-SendRoutingInfoForSM (SRI-SM)
  • MAP-ProvideSubscriberInformation (PSI)
  • MAP-SubscriberLocationReport (SLR)

What is a SMLC?

Creativity Software’s SMLC (SMLC / SAS / E-SMLC ) can be provided as a standalone unit, or co-located with the GMLC, depending on the telecom mobile network architecture required. This flexibility is a key strength, allowing Creativity Software to meet the requirements of different network configurations and integration with equipment from different vendors. It can be configured as either an SMLC for GSM networks and their derivatives, or as a fully standards-compliant PDE for CDMA networks.

SMLC for Mobile Network Operators – How it works

Location Services (LCS) cover services using the positional (geographical) location of mobile user’s equipment (UE) to offer a range of value added services. The location of a user’s mobile is defined in terms of latitude and longitude coordinates. The accuracy depends on the particular technique used to locate the mobile. Several mobile industry variants are currently deployed. The method for ‘requesting’ a user’s mobile location and the resultant network generated messages are standardised regardless of the location technique in use. As mobile networks can support multiple BSCs, Creativity Software’s SMLC platform can support connectivity to a number of BSCs via the standard Lb interface. It fully supports the 3GPP standardised network infrastructure for Location Services. This allows the SMLC to obtain radio measurements from the widest range of sources to determine the position of any target UE within the network.

Key Features / Support for the following interfaces:

  • Iupc Interface between RNC and SAS (RNC interface)
  • Lb Interface between SMLC and BSC (BSC interface)
  • Lc Interface between GMLC and gsmSCF (CAMEL interface)
  • Le Interface between External User and MLC (external interface)
  • Lh Interface between GMLC and HLR (HLR interface)
  • Lg Interface between GMLC and VMSC (gateway MLC interface)
  • SLh Interface between GMLC and HSS
  • SLg Interface between GMLC and MME
  • SLs Interface between E-SMLC and MME
  • Sh Interface between application server and HSS
