`
`NETWORK BASED CONTROL OF REPORT MESSAGES IN A WIRELESS
`
`COMMUNICATIONS NETWORK
`
`TECHNICAL FIELD
`
`This disclosure pertains to a method in a network node, a method in user equipment, a network
`
`5
`
`node and user equipment in a wireless communications network. More particularly, there is
`
`provided mechanisms for network based control of report messages comprising logged
`
`measurements in a wireless communications network.
`
`BACKGROUND
`
`In a typical cellular radio system, wireless terminals, also known as mobile stations and/or
`
`10 User Equipments units (UEs), communicate via a Radio Access Network (RAN) to one or
`
`more core networks. The wireless terminals, hereinafter called UEs which is the same as User
`
`Equipments, can also be mobile telephones, i.e. "cellular" telephones, and laptops with
`
`wireless capability e.g., mobile termination, and thus are, for example, portable, pocket, hand(cid:173)
`
`held, computer-included, or car-mounted mobile devices which communicate voice and/or data
`
`15
`
`via the RAN.
`
`The RAN normally covers a geographical area which is divided into cell areas, also denoted
`
`cells, with each cell area being served by a base station e.g., a Radio Base Station (RBS),
`
`which in some networks is also called "NodeB" or "B node". A cell is a geographical area
`
`where radio coverage is provided by base station equipment at a base station site. Each cell is
`
`2 0
`
`identified by an identity within the local radio area, which is broadcast in the cell. The base
`
`station communicates over the air interface operating on radio frequencies with the UEs within
`
`range of the base stations.
`
`In some versions, particularly earlier versions of the RAN, several base stations are typically
`
`connected, e.g., by landlines or microwave, to a Radio Network Controller (RNC). The RNC,
`
`2 5
`
`also sometimes termed a Base Station Controller (BSC), supervises and coordinates various
`
`activities of the plural base stations connected thereto. The radio network controllers are
`
`typically connected to one or more core networks.
`
`The Universal Mobile Telecommunications System (UMTS) is a third generation mobile
`
`communication system, which evolved from the Global System for Mobile Communications
`
`IPR2022-00459
`Apple EX1002 Page 5
`
`
`
`P32817
`
`2
`
`(GSM), and is intended to provide improved mobile communication services based on
`
`Wideband Code Division Multiple Access (WCDMA) access technology. UTRAN is
`
`essentially a radio access network using wideband code division multiple access for user
`
`equipment units (UEs). The Third Generation Partnership Project (3GPP) has undertaken to
`
`5
`
`evolve further the UTRAN and GSM based radio access network technologies.
`
`Long Term Evolution (LTE) is a variant of a 3GPP radio access technology wherein the radio
`
`base station nodes are connected directly to a core network rather than to RNCs. In general, in
`
`LTE the functions of the RNC node are performed by the RBSs. As such, the RAN of an LTE
`
`system has an essentially "flat" architecture comprising RBSs without reporting to RNCs. In
`
`10
`
`LTE networks the base station(s) is/are called eNodeB(s) or eNB(s).
`
`3GPP is in the process of defining solutions for Minimizing Drive Tests (MDT). The intention
`
`of the Minimizing Drive Tests (MDT) work is documented in 3GPP TR 36.805 V9.0.0 (2009-
`
`12), 3rd Generation Partnership Project; Technical Specification Group Radio Access
`
`Network; Study on Minimization of drive-tests in Next Generation Networks (Release 9).
`
`15
`
`Stage 2 of Minimizing Drive Tests (MDT) is currently being developed in TS 37.320, i.e.,
`
`3GPP TS 37.320, "Radio measurement collection for Minimization of Drive Tests (MDT);
`
`Overall description; Stage 2". MDT Stage 2 includes a UE measurement logging function and
`
`immediate reporting function. The 3GPP TS 37.320 document essentially focuses on the UE
`
`measurement logging function.
`
`2 0 An important use case for MDT is coverage optimization. For this purpose following UE
`
`measurements, or similar functionalities, are considered for DE-internal logging: Periodic, e.g.
`
`one every 5s, downlink pilot signal strength measurements; a serving cell becomes worse than
`
`threshold; transmit power headroom becomes less than threshold; Paging Channel Failure i.e.
`
`Paging Control CHannel (PCCH) decode error; and Broadcast Channel failure.
`
`2 5
`
`The network can request the UE to perform logging of measurements. The UE executes
`
`measurements and logs these measurements internally in a sequential manner, containing, e.g.,
`
`some hour of logged measurement information.
`
`As described in Fig. 1, the UE indicates to the network if it has available log i.e. available
`
`logged measurements. The network node i.e. eNB/RNC determines if it should request the
`
`3 0
`
`logged measurements or not. If it decides to do so then a request is sent to the UE to deliver the
`
`IPR2022-00459
`Apple EX1002 Page 6
`
`
`
`P32817
`
`3
`
`log in a report message. From the eNB/RNC, the reported logged measurements may further be
`
`sent to an OAM server or similar.
`
`The current 3GPP assumptions on this log (i.e. logged measurements) feature are, e.g., as
`
`follows: the UE is required to maintain only one log at a time; one log only contains
`
`5 measurement information collected in one Radio Access Technology (RAT); a log can only be
`
`reported and indicated when the UE is in connected state; If UE is requested to start logging,
`
`e.g., by configuration, a possibly old log and configuration stored in UE is erased.
`
`What the logged measurement report message in signal number 4 in Fig. 1 should look like has
`
`not yet been decided, as of the filing of this application. Some proposals for management of
`
`10 measurement report have been proffered.
`
`As one example proposal for management of measurement reports, it has been suggested that a
`
`log i.e. logged measurements, are to be sent in a single packet, and keeping that single packet
`
`within the size limits of a Packet Data Convergence Protocol (PDCP) Protocol Data Unit
`
`(PDU). Keeping the single packet within the size limits of a PDCP PDU makes it possible to
`
`15
`
`use a Radio Resource Control RRC message for reporting without being segmented into
`
`several smaller packets before being sent to the receiving node i.e., the eNB or NB/RNC in
`
`LTE or UMTS, respectively. One option of this proposal would be limiting the maximum size
`
`of a log in a UE to one RRC message that fits into one PDCP payload packet.
`
`As another example proposal for management of measurement reports, it has been suggested to
`
`2 0
`
`send a log i.e. a logged measurement that is larger than a RRC message with several RRC
`
`messages.
`
`However, there are disadvantages to both example proposals mentioned above. For example,
`
`limiting the log size could prevent logging to complete for the whole configured run time i.e.
`
`logging duration, which can be several hours. The log could fill the limited log buffer in the
`
`2 5 UE before any measurement report has been possible to send to the network node. Before the
`
`configured logging duration time has ended, the UE would stop the logging so that to only
`
`allow the log size to be a single packet e.g. single RRC packet, and relevant measurements
`
`reports may not thereafter be logged. Also in the current MDT configuration a start time for the
`
`logging is not configurable. This means that for a prolonged logging campaign a long period
`
`3 0
`
`between logging instances may be needed in the MDT configuration, alternatively new MDT
`
`IPR2022-00459
`Apple EX1002 Page 7
`
`
`
`P32817
`
`4
`
`configuration needs to be provided from the OAM periodically to be conveyed to MDT
`
`capable UEs.
`
`For the other proposal, sending too many RRC packets in a row could, in poor radio
`
`environments or when handover would occur, create problems with the radio connections and
`
`5
`
`could also create unnecessary radio link failures that will make the users suffer and logged data
`
`be lost.
`
`SUMMARY
`
`The technology disclosed herein concerns network based control of report messages
`
`comprising logged measurements in a wireless communications network, which overcomes at
`
`10
`
`least some of the above mentioned disadvantages and which allows multiple partial report
`
`messages to be sent.
`
`In accordance with some example embodiments, a UE that has stored logged data i.e. logged
`
`measurements that are bigger than a single transmission packet, i.e. report message, segments
`
`the data and sends only a portion of the data that fits into a single report message, and also
`
`15
`
`indicates that more logged measurements exists at the UE.
`
`In a first example of embodiment, there is disclosed a method in a network node for network
`
`based control of report messages in a wireless communications network. The network node
`
`being configured to serve a user equipment, UE, and to receive report messages from the user
`
`equipment. The method comprises sending a request to the UE to start transmitting logged
`
`2 0 measurements in a report message. The network node then receives the report message
`
`comprising the logged measurements from the UE, and determines if the received report
`
`message comprises an indicator of additional logged measurements not yet transmitted, and if
`
`so, decides if the additional logged measurements need to be requested.
`
`In a second example of an embodiment there is disclosed a network node for network based
`
`2 5
`
`control of report messages in a wireless communications network. The network node being
`
`configured to serve a user equipment, UE, and to receive report messages from the user
`
`equipment. The network node comprises a network node communications interface and a
`
`network node processor circuit. The network node communications interface being configured
`
`to send a request to the UE to start transmitting logged measurements in a report message, and
`
`3 0
`
`to receive the report message comprising the logged measurements. The network node
`
`IPR2022-00459
`Apple EX1002 Page 8
`
`
`
`P32817
`
`5
`
`processor circuit being configured to determine if the received report message comprises an
`
`indicator of additional logged measurements not yet transmitted; and if so, to decide if the
`
`additional logged measurements need to be requested.
`
`In a third example of an embodiment, there is disclosed a method in a User Equipment, UE, for
`
`5
`
`assisting in network based control of report messages in a wireless communications network.
`
`The UE is being in connection with a serving network node and configured to transmit report
`
`messages to the network node upon request. The UE is further configured to periodically
`
`perform radio condition measurements and store the periodically performed measurements in a
`
`UE buffer as logged measurements. The method comprising: receiving a request, in the UE,
`
`10
`
`from the network node to start transmitting logged measurements in a report message;
`
`determining if the logged measurements fit in the report message; and if not, including in the
`
`report message an indicator of additional logged measurements not yet transmitted; and,
`
`transmitting the report message, comprising the indicator, to the network node as a response to
`
`the request.
`
`15
`
`In a fourth example of an embodiment, there is disclosed a User Equipment, UE, for assisting
`
`in a network based control of report messages in a wireless communications network. The UE
`
`is being in connection with a serving network node and is configured to transmit report
`
`messages to the network node. The UE is further configured to periodically perform radio
`
`condition measurements and store the periodically performed measurements in a buffer as
`
`2 0
`
`logged measurements. The UE comprises a UE communications interface and a UE processor
`
`circuit. The UE communications interface is configured to receive a request from the network
`
`node to start transmitting logged measurements in a report message, and to transmit the report
`
`message comprising the logged measurements. The UE processor circuit is configured to
`
`determine if the logged measurements fits in the report message, and if not, indicating in the
`
`2 5
`
`report message to be transmitted an existents of additional logged measurements not yet
`
`transmitted.
`
`An advantage achieved by some of the above mentioned embodiments is that due to use of
`
`indicator in report message of further remaining logged measurements providing the network,
`
`i.e. a network node, with information needed to decide a timing of transmission of the logged
`
`3 0 measurements and a timing of when more logged measurements should be requested.
`
`IPR2022-00459
`Apple EX1002 Page 9
`
`
`
`P32817
`
`6
`
`Another advantage achieved by at least some of the above mentioned embodiments is to make
`
`it possible to have longer logging duration and/or conduct more frequent measurements
`
`without overflow in log memory in UE e.g. UE buffer.
`
`Another advantage achieved by some of the above mentioned embodiments is to provide the
`
`5
`
`network node with information about logged measurements making it possible to determine the
`
`amount of logged measurements kept in a UE.
`

`
`DETAILED DESCRIPTION
`
`Fig. 2 illustrates portions of an example embodiment of a communications system/network,
`
`and particularly portions of a Radio Access Network (RAN) 20 comprising at least one
`
`network node 28 and a wireless terminal, hereinafter denoted User Equipment, (UE) 30.
`
`Depending on a particular type of RAN utilized and delegation of nodal responsibilities, the
`
`IPR2022-00459
`Apple EX1002 Page 10
`
`
`
`P32817
`
`7
`
`network node 28 may be a base station node e.g., an NodeB in UMTS or an eNodeB in Long
`
`Term Evolution (LTE)) or a Radio Network Controller (RNC) node in UMTS. Thus, the UE
`
`30 communicates over radio interface 32 with the network node 28, either directly over radio
`
`interface 32 with the network node 28 in case of the network node 28 being a base station type
`
`5
`
`node, or over the radio interface 32 and through a base station in the case of the network node
`
`28 being a radio network controller (RNC) node or an Mobility Management Entity (MME)
`
`which is a control node which processes signaling between the UE and the Core Network (CN)
`
`and provides Visitor Location Register (VLR) functionality for the Evolved Packet System
`
`(EPS).
`
`10 As mentioned above, the UE 30 can be a mobile station such as a mobile telephone ("cellular"
`
`telephone) or laptop with wireless capability ( e.g., mobile termination), and thus can be, for
`
`example, a portable, pocket, hand-held, computer-included, or car-mounted mobile device
`
`which communicates voice and/or data via radio access network.
`
`In accordance with one of its aspect, the technology disclosed concerns generation and/or
`
`15
`
`transmission and/or use of multiple partial report messages with logged measurements such as
`
`MDT log packets, also denoted MDT log or MDT log data. As such, Fig. 2 shows an example
`
`embodiment of network node 28 or UE 30, which comprises a UE communication interface 42
`
`and a UE processor circuit 40. Note that the UE may be seen as a serving point. The UE
`
`processor circuit may include a buffer 44, i.e. UE buffer, for storing logged measurements, not
`
`2 0
`
`shown in figure, and in another embodiment the buffer 44 is within the UE 30.
`
`Fig. 2 also illustrates network node 28 as comprising a network node processor circuit 50 and
`
`network node communications interface 52 (i.e. a communications interface of the network
`
`node). The network node processor circuit 50 may be, or comprise, a logged measurements
`
`requestor/processor (not shown in figure) to be used for requesting logged measurements, such
`
`25
`
`as MDT log, in report message(s).
`
`According to one example of an embodiment, the network node 28 is used for network based
`
`control of report messages comprising logged measurements in a wireless communications
`
`network, the network node 28 being configured to serve the UE 30, UE, and to receive report
`
`messages from the UE 30.

`

`
`Continuing with the description of Fig. 2, the network node communications interface 52 is, or
`
`may be, configured to send request(s) to the UE 30 to start transmitting logged measurement(s)
`
`in report message(s), and to receive
`
`the report message(s) comprising
`
`the
`
`logged
`
`measurements. The logged measurements may compnse one or more of the following:
`
`5 measurement time stamps for each performed measurement; UE buffer state condition;
`
`positioning information of UE; periodically measured downlink pilot signal strength; serving
`
`cell conditions; transmit power headroom conditions; paging channel failure(s ); maximum
`
`required memory supported by UE; and broadcast channel failure(s).
`
`According to one embodiment, the network node communications interface 52 may be
`
`10
`
`configured to receive, from the UE 30, an indication of existents of logged measurements that
`
`are available. Note, that the "additional logged measurements" indicator is conveyed in the UE
`
`information report message while the indication of logged measurements available is conveyed
`
`in already existing/specified signaling.
`
`According to one embodiment, the network node communications interface 52 may be
`
`15
`
`configured to request the report message( s) directly from the UE 3 0 or from another network
`
`node, e.g. RNC, MME, RBS or other similar node.
`
`According to one embodiment, the network node communications interface 52 may be
`
`configured to request the report message upon receiving a UE access request initiated by a UE
`
`handover procedure from another network node to the network node. The request may for
`
`2 0
`
`example be a RRC connection request. The network node communications interface 52 may
`
`also be configured to receive a network node message from the other network node i.e. another
`
`eNodeB, RNC or RBS, comprising UE specific information. The UE specific information may
`
`further comprise the indicator indicating additional logged measurements not yet transmitted.
`
`The network node processor circuit 50, mentioned above in relation to Fig.2, is configured to
`
`2 5
`
`determine if the received report message( s) comprises an indicator of additional logged
`
`measurement( s) not yet transmitted; and if so, to decide if the additional logged measurements
`
`need to be requested. According to one embodiment, the network node processor circuit 50
`
`may be configured to decide if the additional logged measurements need to be requested based
`
`on one or more of the following: interference level experienced in a cell; radio condition
`
`3 0 measurements experienced in a cell; available radio resource; network node capacity; UE
`
`buffer state condition etc.

`

`
`According to one embodiment, the network node processor circuit 50 may be configured to
`
`determine if the indicator indicates that there are logged measurements in a UE buffer 44 that
`
`do, or do not, fit in a single subsequent report message.
`
`According to one embodiment, the network node processor circuit 50 may be configured to
`
`5
`
`decide to request all the logged measurements in the buffer 44 of the UE in one subsequent
`
`request, or repeatedly upon receiving each report message. The decision may also be based on
`
`received status information of the buffer 44 in the UE 30 being for example overloaded. Note
`
`that configured to or adapted to in relation to functionality of circuits and devices mentioned
`
`above and throughout the whole disclosure are expressions that may be used having a similar
`
`1 0
`
`or same meamng.
`
`It should be appreciated that the network node processor circuit 50 may comprise an MDT log
`
`requestor/processor 50' (not shown in Fig. 2) which may be implemented in platform fashion,
`
`e.g., implemented by a computer/processor executing instructions of non-transient signals
`
`and/or by a circuit.
`
`15
`
`Likewise from a UE perspective, reference made to Fig. 2, the UE 30 may be, or is, used for
`
`assisting in network based control of report messages comprising logged measurements in a
`
`wireless communications network. The UE 30 is being in connection with the serving network
`
`node 28 and is configured to transmit report message(s) to the network node 30. The UE 30
`
`may further be configured to periodically perform radio condition measurements and store the
`
`2 0
`
`periodically performed measurements in the buffer 44 as logged measurements. Such logged
`
`measurements may be MDT log reports.
`
`The UE communications interface 42 mentioned above in relation to Fig. 2, is configured to
`
`receive a request from the network node 28 to start transmitting logged measurements in report
`
`message(s), and to transmit/send the report message(s) comprising the logged measurements.
`
`2 5
`
`The UE processor circuit 40 is configured to determine if the logged measurements fits in the
`
`report message( s ), and if not, indicating in the report message to be transmitted an existents of
`
`additional logged measurements not yet transmitted.
`
`According to one embodiment of an example implementation of a UE 30 in which the UE
`
`processor circuit 40 may be, or may comprise, a multiple partial MDT log reporter 40' (Fig. 2
`
`30
`
`dashed lines). The multiple partial MDT log reporter 40' may comprise a log report generator
`
`IPR2022-00459

`
`
`
`P32817
`
`10
`
`and data logging unit (not shown in Fig. 2). The multiple partial MDT log reporter 40' works
`
`in conjunction with a measurement unit (not shown in Fig. 2), and stores records of
`
`measurements in data logging unit. The log report generator may further comprise a packet
`
`identifier generator and "more data" i.e. additional data, flag
