15 Interception of Messaging Services

33.1083G Security3GPPHandover interface for Lawful Interception (LI)Release 17TS

15.1 Overview

The capabilities defined in this clause apply when the interception of messaging services shall be separated from the interception of all other services. This clause applies to the messaging services identified in Clause 5.13 of TS 33.106 [18].

For messaging services, separated delivery when SMS events are detected, the CSP shall be able to use existing intercept capabilities defined in this specification, but isolatable to only deliver messaging services when specified by a lawful authorisation. TS 33.107 [19] defines the SMS events to be reported. This clause will identify the set of event reports that are to be sent from the DF to the LEMF to achieve this separated delivery based on capabilities that already exist in the rest of this specification.

The network nodes, involved in providing the interception of messaging services, shall be determined based on the deployment configuration and the messaging scenario.

When lawfully authorized, Law Enforcement requires access to CC and IRI for the events pertaining to the target’s authorization, access to, and use of message services, independent of the deployed service architecture. This includes where the communications between the target and associates are sent and received over separate channels, or may be accessed at different ICEs at different geographical locations in the service provider’s network.

15.2 SMS

15.2.1 Introduction

LI for SMS over a GPRS and UMTS access is specified in Clause 6. LI for SMS over IMS (using IMS SIP signalling handled by the core network) which can be used in conjunction with LTE access as well as other non-3GPP IP based access is defined in Clause 7.

15.2.2 SMS over GPRS/UMTS

For separate delivery of SMS when SMS is used in conjunction with GPRS or UMTS access, the following records shall be sent by DF2 to the LEMF:

1) SMS MO and SMS MT Communication REPORT Records (Clause 6.5.1.1).

2) HLR Related REPORT Records:

a. Serving System REPORT Record (6.5.1.1);

b. Cancel location REPORT Record (6.5.1.1);

c. Register location REPORT Record (6.5.1.1);

d. Location information request REPORT Record (6.5.1.1).

The above REPORT Records shall be reported from DF2 to the LEMF independent of any other services that may or may not be intercepted.

15.2.3 SMS over IMS

For separate delivery of SMS when SMS over IMS (using IMS SIP signalling handled by the core network) is used, the following REPORT Records shall be reported by DF2 to the LEMF:

1) SMS over IP REPORT Record (see Table 15.2.3.1).

2) HSS related REPORT Records:

a. Serving System (6.5.1.1) or Serving Evolved Packet System (10.5.1.1) for use when roaming

b. Registration termination or Cancel Location (6.1.1.1 or 10.5.1.1);

c. Register location REPORT Record (6.5.1.1 or 10.5.1.1);

d. Location information request REPORT Record (6.5.1.1. or 10.5.1.1).

The above REPORT Records shall be able to be reported from DF2 to the LEMF independent of any other services that may or may not be intercepted.

15.3 MMS

15.3.1 Introduction

LI for Separated Delivery of MMS (see Clause 18.3 of [19]), the events of Clause 18.3 need to be reported to the LEMF from DF2 and for CC from DF3, respectively. A Report record shall be utilized to report the IRI events while a CC shall be reported as described in this clause using a ULIC header.

The CC PDU contains the content of an MMS.

15.3.2 Identifiers

15.3.2.1 Overview

Specific identifiers are necessary to identify a target for interception uniquely and to correlate IRI and CC, which is conveyed over the different handover interfaces (HI2 and HI3). The identifiers are defined in the clauses below.

For the delivery of CC, the MMS Proxy-Relay provides correlation numbers and target identities to DF3. The MMS Proxy-Relay reports the IRI associated with the MMS services.

For the delivery of CC and IRI, the MMS Proxy-Relay provides correlation numbers and target identities to the DF2 and DF3. For a given target the correlation number for a given MMS is unique across all MMS involving the target.

15.3.2.2 Lawful Interception Identifier

For each target identity related to an interception measure, the authorized operator (CSP) shall assign a Lawful Interception Identifier (LIID), which has been agreed between the LEA and the operator (CSP). This shall be a LIID specific to MMS interception, per national regulation.

Using an indirect identification, pointing to a target identity makes it easier to keep the knowledge about a specific target limited within the authorized operator (CSP) and the handling agents at the LEA.

The LIID is a component of the CC delivery procedure and of the IRI records. It shall be used within any information exchanged at the handover interfaces HI2 and HI3 for identification and correlation purposes.

The LIID format shall consist of alphanumeric characters. It might for example, among other information, contain a lawful authorization reference number, and the date, when the lawful authorization was issued.

The authorized operator (CSP) shall either enter, based on an agreement with each LEA, a unique LIID for each target identity of the target or a single LIID for multiple target identities all pertaining to the same target.

If more than one LEA intercepts the same target identity, there shall be unique LIIDs assigned relating to each LEA.

15.3.2.3 Correlation Number

For a given target the Correlation Number is for a given MMS is unique across all MMS involving the target and used for the following purpose:

– correlate CC with IRI.

NOTE: The Correlation Number is at a minimum unique for each concurrent communication of a target within a lawful authorization.

15.3.6 IRI for MMS

15.3.6.1 General

The events defined in TS 33.107 [19] are used to generate records for the delivery via HI2.

There are multiple different event types received at DF2 level. According to each event, a Record is sent to the LEMF if this is required. The following table gives the mapping between event type received at DF2 level and record type sent to the LEMF.

15.3.6.2 Events and Event Information

15.3.6.2.1 Overview

This clause describes the information sent from the Delivery Function (DF) to the Law Enforcement Monitoring Facility (LEMF) to support Lawful Interception (LI). The information is described as records and information carried by a record. This focus is on describing the information being transferred to the LEMF.

The IRI events and data are encoded into records as defined in the Table 15.3.6.1.1 Mapping between MMS Events and HI2 records type and Annex B.15 Intercept related information (HI2). IRI is described in terms of a ‘causing event’ and information associated with that event. Within each IRI record there is a set of events and associated information elements to support the particular service.

The communication events described in Table 15.3.6.1.1: Mapping between MMS Events and HI2 record type and Table 15.3.6.1.2: Mapping between Events information and IRI information convey the basic information for reporting the disposition of a communication. This clause describes those events and supporting information.

Each record described in this clause consists of a set of parameters. Each parameter is either:

– mandatory (M) required for the record,

– conditional (C) required in situations where a condition is met (the condition is given in the Description), or

– optional (O) provided at the discretion of the implementation.

The information to be carried by each parameter is identified. Both optional and conditional parameters are considered to be OPTIONAL syntactically in ASN.1 Stage 3 descriptions. The Stage 2 inclusion takes precedence over Stage 3 syntax.

15.3.6.2.2 REPORT record information

The REPORT record is used to convey the events of MMS service interception.

The REPORT record shall be triggered when:

– the target sends a MMS;

– the target receives a notification of an incoming MMS;

– the target responds to the notification of an incoming MMS;

– an MMS is retrieved by the target;

– the target acknowledges to the retrieved MMS;

– the target forwards an MMS;

– the target stores an MMS in the Mmbox;

– the target uploads an MMS to the Mmbox;

– the target deletes a MMS stored in the Mmbox;

– the target receives a MMS Delivery report;

– the target sends a MMS Read Reply;

– the target receives a MMS Read Reply;

– the target receives a MMS cancel request;

– the target sends a MMbox view request;

– the target receives a confirmation of a sent MMbox View request.
