+== Configuring OsmoPCU
+
+Contrary to other network elements (like OsmoBSC, OsmoNITB), the
+OsmoPCU has a relatively simple minimum configuration.
+
+This is primarily because most of the PCU configuration happens
+indirectly from the BSC, who passes the configuation over A-bis OML via
+OsmoBTS and its PCU socket into OsmoPCU.
+
+A minimal OsmoPCU configuration file is provided below for your reference:
+
+.Example: Minimal OsmoPCU configuration file (`osmo-pcu.cfg`)
+----
+pcu
+ flow-control-interval 10 <1>
+ cs 2 <2>
+ alloc-algorithm dynamic <3>
+ alpha 0 <4>
+ gamma 0
+----
+<1> send a BSSGP flow-control PDU every 10 seconds
+<2> start a TBF with the initial coding scheme 2
+<3> dynamically chose between single-slot or multi-slot TBF allocations
+ depending on system load
+<4> disable MS power control loop
+
+However, there are plenty of tuning parameters for people interested to
+optimize PCU throughput or latency according to their requirements.
+
+=== Configuring the Coding Schemes and Rate Adaption
+
+The BSC includes a bit-mask of permitted [E]GPRS coding schemes as part
+of the A-bis OML configuration. This is passed from the BTS via the PCU
+socket into OsmoPCU.
+
+Some additional parameters can be set as described below.
+
+==== Initial Coding Scheme
+
+You can use the `cs <1-4> [<1-4>]` command at the `pcu` VTY config node
+to set the initial GPRS coding scheme to be used. The optional second
+value allows to specify a different initial coding scheme for uplink.
+
+==== Maximum Coding Scheme
+
+You can use the `cs max <1-4> [<1-4>]` command at the `pcu` VTY config
+node to set the maximum coding scheme that should be used as part of the
+rate adaption.
+
+==== Rate Adaption Error Thresholds
+
+You can use the `cs threshold <0-100> <0-100>` command at the `pcu` VTY
+config node to determine the upper and lower limit for the error rate
+percentage to use in the rate adaption. If the upper threshold is
+reached, a lower coding sheme is chosen, and if the lower threshold is
+reached, a higher coding scheme is chosen.
+
+==== Rate Adation Link Quality Thresholds
+
+You can use the `cs link-quality-ranges cs1 <0-35> cs2 <0-35> <0-35> cs3
+<0-35> <0-35> cs4 <0-35>` command at the `pcu` VTY config node to tune
+the link quality ranges for the respective coding schemes.
+
+==== Data Size based CS downgrade Threshold
+
+You can use the `cs downgrade-threshold <1-10000>` command at the `pcu`
+VTY config node to ask the PCU to down-grade the coding scheme if less
+than the specified number of octets are left to be transmitted.
+
+=== Miscellaneous Configuration / Tuning Parameters
+
+==== Downlink TBF idle time
+
+After a down-link TBF is idle (all data in the current LLC downlink
+queue for the MS has been transmitted), we can keep the TBF established
+for a configurable time. This avoids having to go through a new one or
+two phase TBF establishment once the next data for downlink arrives.
+
+You can use the `dl-tbf-idle-time <1-5000>` to specify that time in
+units of milli-seconds. The default is 2 seconds.
+
+==== MS idle time
+
+Using the `ms-idle-time <1-7200>` command at the `pcu` VTY config node
+you can configure the number of seconds for which the PCU should keep
+the MS data structure alive before releasing it if there are no active
+TBF for this MS.
+
+The OsmoPCU default value is 60 seconds, which is slightly more than
+what 3GPP TS 24.008 recommends for T3314 (44s).
+
+The MS data structure only consumes memory in the PCU and does not
+require any resources of the air interface.
+
+==== Forcing two-phase access
+
+If the MS is using a single-phase access, you can still force it to
+use a two-phase access using the `two-phase-access` VTY configuration
+command at the `pcu` VTY config node.
+
+=== Configuring BSSGP flow control
+
+BSSGP between SGSN and PCU contains a two-level nested flow control
+mechanism:
+
+. one global flow control instance for the overall (downlink) traffic
+ from the SGSN to this PCU
+. a per-MS flow control instance for each individual MS served by this
+ PCU
+
+Each of the flow control instance is implemented as a TBF (token bucket
+filter).
+
+==== Normal BSSGP Flow Control Tuning parameters
+
+You can use the following commands at the `pcu` VTY config node to tune
+the BSSGP flow control parameters:
+
+`flow-control-interval <1-10>`::
+ configure the interval (in seconds) between subsequent flow
+ control PDUs from PCU to SGSN
+`flow-control bucket-time <1-65534>`::
+ set the target downlink maximum queueing time in centi-seconds.
+ The PCU will attempt to adjust the advertised bucket size to match this
+ target.
+
+==== Extended BSSGP Flow Control Tuning parameters
+
+There are some extended flow control related parameters at the `pcu` VTY
+config node that override the automatic flow control as specified in the
+BSSGP specification. Use them with care!
+
+`flow-control force-bvc-bucket-size <1-6553500>`::
+ force the BVC (global) bucket size to the given number of octets
+`flow-control force-bvc-leak-rate <1-6553500>`::
+ force the BVC (global) bucket leak rate to the given number of bits/s
+`flow-control force-ms-bucket-size <1-6553500>`::
+ force the per-MS bucket size to the given number of octets
+`flow-control force-ms-leak-rate <1-6553500>`::
+ force the per-MS bucket leak rate to the given number of bits/s
+
+
+=== Configuring LLC queue
+
+The downlink LLC queue in the PCU towards the MS can be tuned with a
+variety of parameters at the `pcu` VTY config node, depending on your
+needs.
+
+`queue lifetime <1-65534>`::
+ Each downlink LLC PDU is assigned a lifetime by the SGSN, which
+ is respected by the PDU *unless* you use this command to
+ override the PDU lifetime with a larger value (in centi-seconds)
+`queue lifetime infinite`::
+ Never drop LLC PDUs, i.e. give them an unlimited lifetime.
+`queue hysteresis <1-65535>`::
+ When the downlink LLC queue is full, the PCU starts dropping
+ packets. Using this parameter, we can set the lifetime
+ hysteresis in centi-seconds, i.e. it will continue discarding
+ until "lifetime - hysteresis" is reached.
+`queue codel`::
+ Use the 'CoDel' (Controlled Delay) scheduling algorithm, which
+ is designed to overcome buffer bloat. It will use a default
+ interval of 4 seconds.
+`queue codel interval <1-1000>`::
+ Use the 'CoDel' (Controlled Delay) scheduling algorithm, which
+ is designed to overcome buffer bloat. Use the specified
+ interval in centi-seconds.
+`queue idle-ack-delay <1-65535>`::
+ Delay the request for an ACK after the last downlink LLC frame
+ by the specified amount of centi-seconds.
+
+
+=== Configuring MS power control
+
+GPRS MS power control works completely different than the close MS power
+control loop in circuit-switched GSM.
+
+Rather than instructing the MS constantly about which transmit power to
+use, some parameters are provided to the MS by which the MS-based power
+control algorithm is tuned.
+
+See 3GPP TS 05.08 for further information on the algorithm and the
+parameters.
+
+You can set those parameters at the `pcu` VTY config node as follows:
+
+`alpha <0-10>`::
+ Alpha parameter for MS power control in units of 0.1.
+ Make sure to set the alpha value at System Information 13 (in
+ the BSC), too!
+`gamma <0-62>`::
+ Set the gamma parameter for MS power control in units of dB.
+
+
+=== Enabling EGPRS
+
+If you would like to test the currently (experimental) EGPRS support of
+OsmoPCU, you can enable it using the `egprs` command at the `pcu` VTY
+config node.
+
+WARNING: EPGRS functionality is highly experimental at the time of this
+writing. Please only use if you actively would like to participate in
+the OsmoPCU EGPRS development and/or testing. You will also need an
+EGPRS capable OsmoBTS+PHY, which means `osmo-bts-sysmo` or
+`osmo-bts-litecell15` with their associated PHY.

+== Overview
+
+=== About OsmoPCU
+
+OsmoPCU is the Osmocom implementation of the GPRS PCU (Packet Control
+Unit) element inside the GPRS network.
+
+The OsmoPCU is co-located within the BTS and connects to OsmoBTS via its
+PCU socket interface.
+
+On the other side, OsmoPCU is connected via the Gb interface to the
+SGSN.

+----
+
+=== Software Components
+
+OsmoPCU consists of a variety of components, including
+
+* Gb interface (NS/BSSGP protocol)
+* `pcu_sock` interface towards OsmoBTS
+* TBF management for uplink and downlink TBF
+* RLC/MAC protocol implementation
+* per-MS context for each MS currently served
+* CSN.1 encoding/decoding routines
+
+==== Gb Implementation
+
+OsmoPCU implements the ETSI/3GPP specified Gb interface, including TS
+08.16 (NS), TS 08.18 (BSSGP) protocols. As transport layer for NS, it
+supports NS/IP (NS encapsulated in UDP/IP).
+
+The actual Gb Implementation is part of the libosmogb library, which is
+in turn part of the libosmocore software package. This allows the same
+Gb implementation to be used from OsmoPCU, OsmoGbProxy as well as
+OsmoSGSN.
+
+==== `pcu_sock` Interface to OsmoBTS
+
+The interface towards OsmoBTS is called 'pcu_sock' and implemented as a
+set of non-standardized primitives over a unix domain socket. The
+default file system path for this socket is `/tmp/pcu_bts`.
+
+The PCU socket can be changed on both OmsoBTS and OsmoPCU to a different
+file/path name, primarily to permit running multiple independent BTS+PCU
+pairs on a single Linux machine without having to use filesystem
+namespaces or other complex configurations.
+
+NOTE: If you change the PCU socket path on OsmoBTS by means of the
+`pcu-socket` VTY configuration command, you must ensure to make the
+identical change on the OsmoPCU side.

+
+=== Gb BSSGP Initialization / PCU bring-up
+
+The BSSGP initialization directly follows NS connection establishment
+described in <<ns_init>>.
+
+OsmoPCU allocates a BVC context for the BVCI given by OsmoBTS, which
+in turn receives it from OsmoBSC or OsmoNITB via OML procedures.
+
+In addition to the BVCI identifying the OsmoPCU side of BSSGP
+connection, there is also special BVCI which is accepted by OsmoPCU in
+accordance with 3GPP TS 08.18 § 5.4.1: BVCI = 0 represents signaling data
+between SGSN and PCU in contrast to PTP (Peer-To-Peer) user's data.
+
+The mapping between BSSGP PDUs and signaling or PTP BVCIs is available
+in 3GPP TS 08.18 Table 5.4.

+
+==== Messages Specific to OsmoPCU
+
+There are no OsmoPCU specific NS messages.
+
+==== Messages Not Implemented by OsmoPCU
+
+All the NS protocol messages from 3GPP TS 08.16 are implemented in OsmoPCU.
+
+=== Details on Compliant NS Messages
+
+[[ns_unit_data]]
+==== NS-UNITDATA
+
+This PDU transfers one NS SDU (specified in 3GPP TS 08.18) between
+OsmoPCU and SGSN. Upon receiving it OsmoPCU passes it to BSSGP
+implementation to handle. It is also sent by BSSGP as necessary - see
+<<bssgp>> for details.
+
+It contains BVCI (<<ie_bvci>>) and NS SDU (<<ie_nssdu>>) IEs.
+
+[[ns_reset]]
+==== NS-RESET
+
+This message is send by OsmoPCU in order to initiate reset procedure
+described in 3GPP TS 08.16 § 7.3. The expected reply is NS-RESET-ACK
+(<<ns_reset_ack>>) message. If no expected reply is received in 3
+seconds than the sending is retried up to 3 times. When this message
+is received it is replied with NS-RESET-ACK (<<ns_reset_ack>>).
+It might be ignored under conditions described in 3GPP TS 08.16 § 7.3.1.
+
+The message conforms to 3GPP TS 08.16 § 9.2.5 specification.
+
+It contains Cause (<<ie_cause>>), NSVCI (<<ie_nsvci>>) and NSEI (<<ie_nsei>>) IEs.
+
+[[ns_reset_ack]]
+==== NS-RESET-ACK
+
+This message is sent as a response to proper NS-RESET (<<ns_reset>>)
+message initiating reset procedure.
+
+The message conforms to 3GPP TS 08.16 § 9.2.6 specification.
+
+It contains NSVCI (<<ie_nsvci>>) and NSEI (<<ie_nsei>>) IEs.
+
+[[ns_block]]
+==== NS-BLOCK
+
+Upon receiving this message corresponding NS-VC is marked as blocked
+by OsmoPCU and NS-BLOCK-ACK (<<ns_block_ack>>) reply is transmitted.
+When this message is sent by OsmoPCU corresponding NS-BLOCK-ACK
+(<<ns_block_ack>>) reply is expected before NS-VC is actually marked
+as blocked. This behavior follows the blocking procedure described in
+3GPP TS 08.16 § 7.2.
+
+The message conforms to 3GPP TS 08.16 § 9.2.3 specification.
+
+It contains Cause (<<ie_cause>>) and NSVCI (<<ie_nsvci>>) IEs.
+
+[[ns_block_ack]]
+==== NS-BLOCK-ACK
+
+This message is sent by OsmoPCU automatically upon reception of
+correct NS-BLOCK (<<ns_block>>) message. It is expected as a reply
+for NS-BLOCK (<<ns_block>>) message sent by OsmoPCU.
+
+The message conforms to 3GPP TS 08.16 § 9.2.4 specification.
+
+It contains NSVCI (<<ie_nsvci>>) IE.
+
+[[ns_unblock]]
+==== NS-UNBLOCK
+
+Upon receiving this message corresponding NS-VC is unblocked by
+OsmoPCU and NS-UNBLOCK-ACK (<<ns_unblock_ack>>) reply is sent. When
+this message is sent by OsmoPCU corresponding NS-UNBLOCK-ACK
+(<<ns_unblock_ack>>) reply is expected before NS-VC is actually marked
+as unblocked. This behavior follows the blocking procedure described
+in 3GPP TS 08.16 § 7.2.
+
+The message conforms to 3GPP TS 08.16 § 9.2.8 specification.
+
+[[ns_unblock_ack]]
+==== NS-UNBLOCK-ACK
+
+Receiving this message notifies OsmoPCU that NS-VC unblocking request
+is confirmed and thus NS-VC is marked as unblocked. This message is
+also sent as a reply to NS-UNBLOCK (<<ns_unblock>>) message.
+
+The message conforms to 3GPP TS 08.16 § 9.2.9 specification.
+
+[[ns_status]]
+==== NS-STATUS
+
+This message is sent to inform other party about error conditions as a
+response to various unexpected PDUs or PDUs with unexpected/missing
+data. If this message is received for unknown NS-VC it is ignored in
+accordance with 3GPP TS 08.16 § 7.5.1, otherwise the error cause is
+logged if present in NS-STATUS.
+
+The message conforms to 3GPP TS 08.16 § 9.2.7 specification.
+
+It contains Cause (<<ie_cause>>) and might (depending on actual error)
+contain NSVCI (<<ie_nsvci>>), NS PDU (<<ie_nspdu>>) and BVCI
+(<<ie_bvci>>) IEs.
+
+[[ns_alive]]
+==== NS-ALIVE
+
+This message is sent periodically to test connectivity according to
+3GPP TS 08.16 § 4.5.3. The expected response is NS-ALIVE-ACK
+(<<ns_alive_ack>>). If no such response arrives within given amount of
+time (3 seconds) than another NS-ALIVE message is sent and failed test
+attempt is recorded. After 10 failed attempts NS connection is
+considered dead and OsmoPCU tries to reconnect.
+
+The message conforms to 3GPP TS 08.16 § 9.2.1 specification.
+
+[[ns_alive_ack]]
+==== NS-ALIVE-ACK
+
+This message is sent automatically in reply to NS-ALIVE (<<ns_alive>>)
+message.
+
+The message conforms to 3GPP TS 08.16 § 9.2.2 specification.
+
+=== Information Elements Overview
+
+All of the IEs handled by OsmoPCU are listed below, with limitations and
+additions to 3GPP TS 08.16 specified in more detail.

+OsmoPCU Gb Protocol Specification
+=================================
+Harald Welte <hwelte@sysmocom.de>
+
+== Introduction
+
+This document describes the Gb interface of *OsmoPCU*. Based on 3GPP TS
+08.16 and 08.18, this document indicates which of the 3GPP specified Gb
+messages and IEs are implemented according to 3GPP specifications, which of
+these are not or not fully implemented, as well as OsmoPCU-specific extensions
+to the Gb interface not specified by 3GPP.
+
+Extensions to the Gb interface specific to OsmoPCU are detailed in this
+document. For details on the messages and IEs that comply with above-mentioned
+3GPP specifications, please refer to those documents.
+

+|===
+
+== Overview
+
+The OsmoPCU Gb interface consists of the NS (Network Services) and
+BSSGP (Base Station Subsystem Gateway Protocol), encapsulated in UDP
+(User Datagram Protocol) and IP (Internet Protocol) version 4.
+Use of other underlying protocols (e. g. Frame Relay) is not supported.
+
+.UDP port numbers used by OsmoPCU Gb/IP
+[options="header",width="50%",cols="35%,65%"]
+|===
+|TCP Port Number|Usage
+|23000|NS over UDP (default port)
+|===
+
+The NS-over-UDP link is established in the PCU -> SGSN direction, i.e.
+the PCU is running as client while the SGSN is running as server.
+
+Establishment of the NS-over-UDP link is only possible after OsmoPCU
+has been configured via the *PCU socket* interface from OsmoBTS.
+
+OsmoBTS in turn receives relevant configuration parameters from
+OsmoBSC or the BSC component inside OsmoNITB.
+

+
+[[ident]]
+=== Identities
+
+The Gb interface identities of the PCU are configured via BSC ->
+OsmoBTS -> PCU Socket. They consist of
+
+NSEI:: NS Equipment Identifier
+NSVCI:: NS Virtual Connection Identifier
+BVCI:: BSSGP Virtual Connection Identifier
+
+For an explanation of those identifiers and their use in the NS and
+BSSGP protocols, please see the relevant 3GPP specifications for NS (TS 08.16)
+and BSSGP (TS 08.18).
+
+In most cases, all above identities belong to different namespaces and
+must be unique within their respective namespace and within the SGSN
+they connect to.
+
+This means that typically each OsmoPCU has one unique set of NSEI,
+NSVCI and BVCI in your network.
