19.2.1.2 Conformance requirements

References: The conformance requirements covered in the present TC are specified in: TS 23.303, clause 5.3.1.1, TS 24.301, clauses 5.5.1.2.2, 5.5.3.2.2, 6.1.1, TS 24.334, clauses 5.1.1, 5.1.2, 6.2.3.2, 6.2.3.4, 6.2.4.2, 6.2.4.4, TS 36.331, clauses 5.2.2.4, 5.2.2.26, 5.10.2.1, 5.10.2.2, 5.10.2.3, 5.10.5. Unless otherwise stated these are Rel-12 requirements.

[TS 23.303, clause 5.3.1.1]

The UE can act as "announcing UE" only in the band designated by the serving PLMN but may act as a "monitoring" UE also in the resources of the serving PLMN and Local PLMNs.

ProSe-enabled UEs which have obtained authorization to participate in ProSe Direct Discovery procedures shall not continue in participating in ProSe Direct Discovery procedures as soon as they detect loss of E-UTRA coverage in the serving PLMN.

[TS 24.301, clause 5.5.1.2.2]

If the UE supports ProSe direct discovery, then the UE shall set the ProSe bit to "ProSe supported" and set the ProSe direct discovery bit to "ProSe direct discovery supported" in the UE network capability IE of the ATTACH REQUEST message.

[TS 24.301, clause 5.5.3.2.2]

The UE in state EMM-REGISTERED shall initiate the tracking area updating procedure by sending a TRACKING AREA UPDATE REQUEST message to the MME,

b) when the periodic tracking area updating timer T3412 expires;

If the UE has to request resources for ProSe direct discovery or Prose direct communication (see 3GPP TS 36.331 [22]), then the UE shall set the "active" flag to 1 in the TRACKING AREA UPDATE REQUEST message.

For all cases except case b, if the UE supports ProSe direct communication, then the UE shall set the ProSe bit to "ProSe supported" and set the ProSe direct communication bit to "ProSe direct communication supported" in the UE network capability IE of the TRACKING AREA UPDATE REQUEST message.

[TS 24.334, clause 5.1.1]

The service authorisation for ProSe direct discovery and ProSe direct communication determines whether the UE is authorised to use ProSe direct discovery announcing or ProSe direct discovery monitoring or both, and to use ProSe direct communication, in a particular PLMN or when not served by E-UTRAN. In this release of the specification, ProSe direct communication is supported only for Public Safety ProSe-enabled UE. The service authorisation is either:

1) pre-configured in the UE. The pre-configured service authorisation may be stored in the ME, or in the USIM as specified in 3GPP TS 31.102 [17], or in both the ME and the USIM. If both the ME and the USIM contain the same parameters, the values stored in the USIM shall take precedence. The UE shall not use the pre-configured service authorisation if the contents of the USIM indicate that the UE is not authorised to use them (see 3GPP TS 31.102 [17]); or

2) transferred between the UE and the ProSe Function over the PC3 interface with the ProSe Direct Services Provisioning Management Object or the ProSe Public Safety Direct Services Provisioning Management Object as specified in 3GPP TS 24.333 [9].

The service authorisation provided by the ProSe Function of the HPLMN for ProSe direct discovery contains a list of PLMNs in which the UE is authorised to use ProSe direct discovery.

[TS 24.334, clause 5.1.2]

The IP address of the ProSe function in the HPLMN may be pre-configured in the UE and in this case, the UE may use the pre-configured IP address. Alternatively, the FQDN of the ProSe Function in the HPLMN may be self-constructed by the UE, i.e. derived from the PLMN ID of the HPLMN. The UE may perform DNS lookup as specified in IETF RFC 1035 [10].

[TS 24.334, clause 6.1.1]

The UE and ProSe Function shall use HTTP 1.1 as specified in IETF RFC 7230 [18] and IETF RFC 7231 [19] as the transport protocol for ProSe messages over the PC3 interface. The ProSe messages described here shall be included in the body of either an HTTP request message or an HTTP response message. The following rules apply:

– The UE initiates ProSe transactions with an HTTP request message containing the PC3 request(s);

– The ProSe Function responds to the requests with an HTTP response message containing the PC3 response(s) for the PC3 request(s); and

– HTTP POST methods are used for PC3 direct discovery procedures.

Optionally, the operator can configure the UE with configuration parameters for establishment of the PDN connection for reaching the HPLMN ProSe Function. If the UE is configured with the configuration parameter for establishment of the PDN connection for reaching the HPLMN ProSe Function (see 3GPP TS 24.333 [9]):

a) if a PDN connection for reaching the HPLMN ProSe Function is not established yet, the UE shall establish the PDN connection for reaching the HPLMN ProSe Function according to the UE configuration and shall send the HTTP request message via the PDN connection for reaching the HPLMN ProSe Function; and

b) if a PDN connection for reaching the HPLMN ProSe Function is already established (e.g. either due to other ProSe feature or due to other application), the UE shall send the HTTP request message via the PDN connection for reaching the HPLMN ProSe Function;

[TS 24.334, clause 6.2.3.2]

Before initiating the monitor request procedure, the UE is configured with the data structure of the ProSe Application IDs it wants to monitor. This step is performed using mechanisms that are out of scope of 3GPP.

If the UE is authorised to perform ProSe direct discovery monitoring in at least one PLMN, it shall initiate a monitor request procedure:

a) when the UE is triggered by an upper layer application to perform ProSe direct discovery monitoring corresponding to a ProSe Application ID and the UE has no valid Discovery Filters corresponding to the requested ProSe Application ID for that upper layer application; or

b) when the TTL timer T4002 assigned by the ProSe Function to a Discovery Filter has expired and the request from upper layers to monitor that ProSe Application ID is still in place.

NOTE 1: To ensure service continuity if the UE needs to keep monitoring the same Discovery Filter, the UE can initiate the monitor request procedure before the TTL timer T4002 assigned by the ProSe Function for a Discovery Filter expires.

The UE initiates the monitor request procedure by sending a DISCOVERY_REQUEST message with a new transaction ID, the ProSe Application ID set to the ProSe Application ID received from upper layers, the command set to "monitor", the UE identity set to the UE’s IMSI, and the Application Identity set to the Application Identity of the upper layer application that requested the monitoring.

NOTE 2: A UE can include one or multiple transactions in one DISCOVERY_REQUEST message for one or more ProSe Application IDs, and receive corresponding <response-monitor> element or <response-reject> element in the DISCOVERY_RESPONSE message for each respective transaction. In the following description of the monitor request procedure, only one transaction is included.

Figure 6.2.3.2.1 illustrates the interaction between the UE and the ProSe Function in the monitor request procedure.

Figure 6.2.3.2.1: Monitor request procedure

[TS 24.334, clause 6.2.3.4]

Upon receipt of the DISCOVERY_RESPONSE message, if the transaction ID contained in the <response-monitor> element matches the value sent by the UE in a DISCOVERY_REQUEST message with the command set to "monitor", the UE shall, for each Discovery Filter assigned by the ProSe Function, stop TTL timer T4002 if running and start TTL timer T4002 with the received value. Otherwise the UE shall discard the DISCOVERY_RESPONSE message and shall not perform the procedures below.

The UE may perform monitor for discovery messages received over the PC5 interface as described below.

For a ProSe Application ID requested by the monitoring UE, the ProSe Function may have assigned one or more Discovery Filters. The UE should apply all assigned Discovery Filters to its monitoring operation. Using these Discovery Filters may result in a match event. In case of a match event, the UE shall consider that the ProSe Application ID it seeks to monitor has been discovered. A match event is defined as follows:

There is a match event when, for any of the ProSe Application Masks in a Discovery Filter, the output of a bitwise AND operation between the ProSe Application Code contained in the received PC5_DISCOVERY message and the ProSe Application Mask, matches the output of a bitwise AND operation between the ProSe Application Mask and the ProSe Application Code contained in the same Discovery Filter.

NOTE: A ProSe Application Mask with all bits set to "1" is assigned by the ProSe Function for full matching.

The UE may instruct the lower layers to start monitoring if all of the following conditions are met:

– the UE is currently authorized to perform monitoring in at least one PLMN;

– the UE has obtained at least one Discovery Filter and their respective TTL timer T4002(s) have not expired; and

– a request from upper layers to monitor for the ProSe Application ID associated with an authorised Application Identity is still in place.

If the UE is in EMM-CONNECTED mode, the monitoring UE shall also trigger the corresponding procedure in lower layers as specified in 3GPP TS 36.331 [12].

During the monitoring operation, the UE receives all PC5_DISCOVERY messages and associated UTC times from the lower layers.

During the monitoring operation, if one of the above conditions is no longer met, the UE may instruct the lower layers to stop monitoring. When the UE stops monitoring, if the UE is in EMM-CONNECTED mode, the UE shall trigger the corresponding procedure in lower layers as specified in 3GPP TS 36.331 [12].

[TS 24.334, clause 6.2.4.2]

The UE shall meet the following pre-conditions before initiating this procedure:

– a request from upper layers to monitor for the ProSe Application ID, which resulted in the matched ProSe Application Code, is still in place;

– the lower layers have provided a "Monitored PLMN ID" value, and UTC time information, along with the discovery message containing a ProSe Application Code; and

– the TTL timer T4002 associated with the Discovery Filter, which resulted in a match event of the ProSe Application Code, has not expired.

If the UE is authorised to perform ProSe direct discovery monitoring in the monitored PLMN, it should initiate a match report procedure:

a) when there is a match event of one of the ProSe Application Codes received from the lower layers, and the UE does not have a corresponding ProSe Application ID already locally stored;

b) when the UE has a locally stored mapping for the ProSe Application Code that resulted in a match event, but the validity timer T4004 of the ProSe Application Code has expired; or

c) when the UE has a locally stored mapping for the ProSe Application Code that resulted in a match event, but the match report refresh timer T4006 of the ProSe Application Code has expired.

The UE initiates the match report procedure by sending a MATCH_REPORT message with a new transaction ID and shall set the message contents as follows:

– the UE shall set the ProSe Application Code to the ProSe Application Code for which there was a match event;

– the UE shall set the UE identity to the UE’s IMSI;

– the UE shall set the UTC-based counter as follows:

– the 28 most significant bits of the UTC-based counter shall be set to the 28 most significant bits of the UTC time provided by the lower layers for the PC5_DISCOVERY message that contained the ProSe Application Code for which there was a match event encoded as specified in subclause 12.2.2.18; and

– the 4 least significant bits of the UTC-based counter shall be set to the 4 least significant bits of the UTC-based counter contained in the PC5_DISCOVERY message that contained the ProSe Application Code for which there was a match event, as specified in 3GPP TS 33.303 [6];

– the UE shall set the MIC to the MIC of the PC5_DISCOVERY message that contained the ProSe Application Code for which there was a match event;

– the UE shall set the Monitored PLMN ID to the PLMN ID of the PLMN where the PC5_DISCOVERY message was received, as provided by the lower layers;

– if the UE was roaming when the match event occurred, the UE shall set the VPLMN ID to the PLMN ID of the PLMN in which the UE was registered when the match event occurred; and

– the UE shall set the Metadata Flag to indicate whether or not it wishes to receive metadata information associated with the ProSe Application ID in the MATCH_REPORT_ACK message from the ProSe Function.

NOTE 1: A UE can include one or multiple transactions in one MATCH_REPORT message for different ProSe Application Codes, and receive corresponding <match-ack> element or <match-reject> element in the MATCH_REPORT_ACK message for each respective transaction. In the following description of match report procedure, only one transaction is included.

NOTE 2: The value of the Metadata Flag is determined through an indication from upper layers in the original request to monitor for a ProSe Application ID.

Figure 6.2.4.2.1 illustrates the interaction between the UE and the ProSe Function in the match report procedure.

Figure 6.2.4.2.1: Match report procedure

[TS 24.334, clause 6.2.4.4]

Upon receipt of the MATCH_REPORT_ACK message, if the transaction ID contained in the <match-ack> element matches the value sent by the UE in a MATCH_REPORT message, the UE shall store the mapping between the ProSe Application Code and ProSe Application ID locally, start timers T4004 and T4006, and may inform the upper layers of this match of the ProSe Application ID. Otherwise the UE shall discard the MATCH_REPORT_ACK message.

Upon receipt of the MATCH_REPORT_ACK message, if the transaction ID contained in the <match-reject> element matches the value sent by the UE in a MATCH_REPORT message and if the received PC3 Control Protocol cause value is #5 "Invalid MIC", as specified in subclause 6.2.4.5, the UE shall stop timer T4004 if it is running.

NOTE 1: It is an implementation specific choice whether the UE informs the upper layers every time a ProSe Application ID triggers a match event, or only the first time this match occurs.

NOTE 2: The UE can also inform the upper layers if a ProSe Application ID is no longer matched, because the validity timer T4004 of the corresponding ProSe Application Code expires.

NOTE 3: The UE can also inform the upper layers if a ProSe Application ID is no longer matched, because the validity timer T4004 of the corresponding ProSe Application Code is stopped upon receiving MATCH_REPORT_ACK message with a <match-reject> element with PC3 Control Protocol cause value #5 "Invalid MIC".

[TS 36.331, clause 5.2.2.4]

1> if the UE is capable of sidelink discovery and is configured by upper layers to receive or transmit sidelink discovery announcements on the primary frequency:

2> if schedulingInfoList indicates that SystemInformationBlockType19 is present and the UE does not have stored a valid version of this system information block:

3> acquire SystemInformationBlockType19;

2> for each of the one or more frequencies included in discInterFreqList, if included in SystemInformationBlockType19 and for which the UE is configured by upper layers to receive sidelink discovery announcements on:

3> if schedulingInfoList indicates that SystemInformationBlockType19 is present and the UE does not have stored a valid version of this system information block:

4> acquire SystemInformationBlockType19;

[TS 36.331, clause 5.2.2.26]

Upon receiving SystemInformationBlockType19, the UE shall:

1> if SystemInformationBlockType19 message includes the discConfig:

2> from the next discovery period, as defined by discPeriod, use the resources indicated by discRxPool for sidelink discovery monitoring, as specified in 5.10.5;

[TS 36.331, clause 5.10.2.1]

Figure 5.10.2-1: Sidelink UE information

The purpose of this procedure is to inform E-UTRAN that the UE is interested or no longer interested to receive sidelink communication or discovery, as well as to request assignment or release of transmission resources for sidelink communication or discovery announcements.

[TS 36.331, clause 5.10.2.2]

A UE capable of sidelink communication or discovery that is in RRC_CONNECTED may initiate the procedure to indicate it is (interested in) receiving sidelink communication or discovery in several cases including upon successful connection establishment, upon change of interest, upon change to a PCell broadcasting SystemInformationBlockType18 or SystemInformationBlockType19. A UE capable of sidelink communication or discovery may initiate the procedure to request assignment of dedicated resources for the concerned sidelink communication transmission or discovery announcements.

Upon initiating the procedure, the UE shall:

1> if SystemInformationBlockType19 is broadcast by the PCell:

2> ensure having a valid version of SystemInformationBlockType19 for the PCell;

2> if configured by upper layers to receive sidelink discovery announcements on a serving frequency or on one or more frequencies included in discInterFreqList, if included in SystemInformationBlockType19:

3> if the UE did not transmit a SidelinkUEInformation message since last entering RRC_CONNECTED state; or

3> if since the last time the UE transmitted a SidelinkUEInformation message the UE connected to a PCell not broadcasting SystemInformationBlockType19; or

3> if the last transmission of the SidelinkUEInformation message did not include discRxInterest:

4> initiate transmission of the SidelinkUEInformation message to indicate it is interested in sidelink discovery reception in accordance with 5.10.2.3;

2> else:

3> if the last transmission of the SidelinkUEInformation message included discRxInterest:

4> initiate transmission of the SidelinkUEInformation message to indicate it is no longer interested in sidelink discovery reception in accordance with 5.10.2.3;

[TS 36.331, clause 5.10.2.3]

The UE shall set the contents of the SidelinkUEInformation message as follows:

1> if SystemInformationBlockType19 is broadcast by the PCell:

2> if configured by upper layers to receive sidelink discovery announcements on a serving frequency or one or more frequencies included in discInterFreqList, if included in SystemInformationBlockType19:

3> include discRxInterest;

The UE shall submit the SidelinkUEInformation message to lower layers for transmission.

[TS 36.331, clause 5.10.5]

A UE capable of sidelink discovery that is configured by upper layers to monitor sidelink discovery announcements shall:

1> for each frequency the UE is configured to monitor sidelink discovery announcements on, prioritising the frequencies included in discInterFreqList, if included in SystemInformationBlockType19:

2> configure lower layers to monitor sidelink discovery announcements using the pool of resources indicated by discRxPool in SystemInformationBlockType19 without affecting normal operation i.e. receive during idle periods or by using a spare receiver;

NOTE 1: The requirement not to affect normal UE operation also applies for the acquisition of sidelink discovery related system and synchronisation information from inter-frequency cells.

NOTE 2: The UE is not required to monitor all pools simultaneously.

NOTE 3: It is up to UE implementation to decide whether a cell is sufficiently good to be used to monitor sidelink discovery announcements.

UE:

– ProSe related configuration

The UE is equipped with a USIM containing values shown in Table 19.2.1.3.1-2, and, relevant to each of the supported services values as specified in TS 36.508 [18], section 4.9.3.1 (e.g. 2 PLMNs are authorised for ProSe Direct Discovery Monitoring).

b3=1: the ME is authorized to use the parameters stored in the USIM or in the ME for ProSe services for Public Safety usage

Depending on implementation, a Rel-12 UE may not support USIM settings for ProSe Direct Discovery Monitoring (pc_disc_public_safety=FALSE, i.e. ProSe Discovery for Public Safety not supported) . Such UEs are expected to provide means for pre-configuring the PLMNs which are authorised for ProSe Direct Discovery Monitoring (e.g. via MMI). The values specified for EFPROSE_MON in TS 36.508 [18], section 4.9.3.1 shall be preconfigured.

– For each PLMN a timer T4005 is assigned long enough not to expire before the TC is completed, e.g. 7 min (For Rel-12 this timer cannot be set in the USIM, it is expected that the UE shall provide means for setting the timer e.g. via MMI).

– The UE is configured with the data structure of the ProSe Application ID (px_ProSeMonApplicationIdentity1) it wants to monitor (This step is performed using UE implementation dependent mechanisms, e.g. MMI command, or, may be pre-loaded in the UE).

– A number of arbitrarily chosen ProSe Application IDs are provided during the test. The UE shall have no knowledge of them before the test is started.

– The UE has no valid Discovery Filters corresponding to the configured ProSe Application ID (px_ProSeMonApplicationIdentity1) nor to any other possibly pre-loaded ProSe Application IDs (this is to ensure that the provided during the test ProSe Application Codes are not known to the UE).

Preamble:

– The UE is in state Switched OFF (state 1) according to TS 36.508 [18].
