  1. Location Configuration Protocols How many do we need? Steve Edge Qualcomm

  2. OMA - Location Configuration Protocols • Location Configuration Protocols defined by OMA • SUPL ULP (User plane Location Protocol) is used to obtain terminal location and convey it to the terminal and/or network (H-SLP or E-SLP) • RLP (Roaming Location Protocol) is used to request and convey location between SLPs • MLP (Mobile Location Protocol) is used to request and convey location to a client (SUPL Agent) • MLP and RLP are also used to support the 3GPP control plane (CP) location solution and are being introduced to support the 3GPP2 CP solution

  3. OMA - Location Configuration Protocols • Protocol characteristics • ULP is ASN.1 defined and uses TCP/IP transport and TLS • MLP and RLP are XML defined and can be transported using various protocols (e.g. HTTP, WSP, SOAP) although only an HTTP 1.1 mapping is currently defined • SUPL is an endorsed location solution for 3GPP IP based emergency calls and location for 3GPP I-WLAN access

  4. OMA - Location Configuration Protocols • The Figure shows the roles of MLP, RLP and ULP to support SUPL 1.0 • In SUPL 2.0, a defined protocol (ILP – Internal Location Protocol) is allowed between the SLC and SPC and SUPL INIT transport from the H-SLP (or E-SLP) to the SET may also use UDP/IP and SIP Push
