This APN +determines which GGSN shall be used, and that in turn determines which +external IP network the MS will be connected to. + +There are two modes in which GGSNs can be configured: + +. static GGSN/APN configuration +. dynamic GGSN/APN configuration + +==== Static GGSN/APN configuration + +In this mode, there is a static list of GGSNs and APNs configured in +OsmoSGSN via the VTY / config file. + +This is a non-standard method outside of the 3GPP specifications for the +SGSN, and is typically only used in private/small GPRS networks without +any access to a GRX. + +.Example: Static GGSN/APN configuration (single catch-all GGSN) +---- +OsmoSGSN(config-sgsn)# gtp local-ip 172.0.0.1 <1> +OsmoSGSN(config-sgsn)# ggsn 0 remote-ip 127.0.0.2 <2> +OsmoSGSN(config-sgsn)# ggsn 0 gtp-version 1 <3> +OsmoSGSN(config-sgsn)# apn * ggsn 0 <4> +---- +<1> Configure the local IP address at the SGSN used for Gp/GTP +<2> Specify the remote IP address of the GGSN (for GGSN 0) +<3> Specify the GTP protocol version used for GGSN 0 +<4> Route all APN names to GGSN 0 + + +==== Dynamic GGSN/APN configuration + +In this mode, the SGSN will use a DNS-based method to perform the lookup +from the APN (as specified by the MS) towards the GGSN IP address. + +This is the official method as per the 3GPP specifications for the SGSN, +and what is used on GRX. + +.Example: Dynamic GGSN/APN configuration +---- +OsmoSGSN(config-sgsn)# gtp local-ip 192.168.0.11 <1> +OsmoSGSN(config-sgsn)# ggsn dynamic <2> +OsmoSGSN(config-sgsn)# grx-dns-add 1.2.3.4 <3> +---- +<1> Configure the local IP address at the SGSN used for Gp/GTP +<2> Enable the dynamic GGSN resolving mode +<3> Specify the IP address of a DNS server for APN resolution + +[[auth-pol]] +=== Authorization Policy + +The authorization policy controls by which rules a subscriber is accepted or +rejected. The possible options range from accepting just all subscribers without +further checking, to a fine grained access-control, handled by an external HLR. + +accept-all:: All subscribers that attempt to attach to the GPRS network are +accepted without further checking. This option is intended to be used for +testing in a controlled environment only. A wide-open network may attract +subscribers from foreign networks and disrupt their service. It is highly +recommended to pick one of the options below. + +remote:: This option allows to connect OsmoSGSN to an external HLR via the +GSUP protocol. This will be the preferred option in larger networks. + +acl-only:: If no external HLR is available, the network operator has the +option to control the access using an access control list. The access control +list contains the IMSI numbers of the allowed subscribers. This method offers +fine grained access control and is ideal for small networks and lab test +environments. + +closed:: This policy mode softens the strict *acl-only* only mode by also +implicitly accepting home network subscribers. The decision is made by the MCC +and MNC part of the IMSI number. The combination of MCC and MNC fully identifies +a subscribers home network, also known as a Home Network Identity (HNI, i.e. +MCC and MNC found at the start of the IMSI, e.g. MCC 901 and MNC 700 with +IMSI 901700000003080). + +NOTE: The policy mode *closed* must not be confused with the equally named +policy that is defined for osmo-nitb! + + +.Example: Assign or change authorization policy +---- +OsmoSGSN> enable +OsmoSGSN# configure terminal +OsmoSGSN(config)# sgsn +OsmoSGSN(config-sgsn)# auth-policy acl-only <1> +OsmoSGSN(config-sgsn)# write <2> +Configuration saved to sgsn.cfg +OsmoSGSN(config-sgsn)# end +OsmoSGSN# disable +OsmoSGSN> +---- +<1> 'acl-only' is selected as authorization policy +<2> Saves current changes to cofiguration to make this policy +persistent + +.Example: Access control list +---- +sgsn + auth-policy acl-only <1> + imsi-acl add 001010000000003 + imsi-acl add 001010000000002 + imsi-acl add 001010000000001 + imsi-acl add 901700000000068 <2> +---- +<1> Set the authorization policy +<2> Add as many subscribers as required + +=== Subscriber Configuration + +As opposed to OsmoNITB, OsmoSGSN does not feature a built-in HLR. + +It can thus operate only in the following two modes: + +.

Accepting subscribers based on internal ACL (access control list), + see also <<auth-pol>> + +==== Accessing an external HLR via GSUP + +The non-standard GSUP protocol was created to provide OsmoSGSN with +access to an external HLR while avoiding the complexities of the +TCAP/MAP protocol stack commonly used by HLRs. + +A custom HLR could either directly implement GSUP, or an external gateway +can be used to convert GSUP to the respective MAP operations. + +The primitives/operations of GSUP are modelled to have a 1:1 +correspondence to their MAP counterparts. However, the encoding is much +simplified by use of a binary TLV encoding similar to Layer 3 of +GSM/GPRS. + +GSUP performs a challenge-response authentication protocol called OAP, +which uses the standard MILENAGE algorithm for mutual authentication +between OsmoSGSN and the HLR/HLR-GW. + +[[sgsn-ex-gsup]] +.Example: Using an external HLR via GSUP +---- +OsmoSGSN(config-sgsn)# gsup remote-ip 2.3.4.5 <1> +OsmoSGSN(config-sgsn)# gsup remote-port 10000 <2> +OsmoSGSN(config-sgsn)# gsup oap-k 000102030405060708090a0b0c0d0e0f <3> +OsmoSGSN(config-sgsn)# gsup oap-opc 101112131415161718191a1b1c1d1e1f <4> +---- +<1> Configure the IP address of the (remote) HLR or HLR-GW +<2> Configure the TCP port of the (remote) HLR or HLR-GW +<3> Specify the OAP shared key +<4> Specify the OAP shared OPC + + +=== CDR configuration + +OsmoSGSN can write a text log file containing CDR (call data records), +which are commonly used for accounting/billing purpose. + +.Example: CDR log file configuration +---- +OsmoSGSN(config-sgsn)# cdr filename /var/log/osmosgsn.cdr +OsmoSGSN(config-sgsn)# cdr interval 600 <1> +---- +<1> Periodically log existing PDP contexts every 600 seconds (10 min) + +The CDR file is a simple CSV file including a header line naming the +individual fields of each CSV line. + +==== CDR CTRL interface + +Independently of whether logging CDR to a file is enabled or not, OsmoSGSN can +also provide delivery of CDR through the CTRL interface.

The header contains a lot of static information that never changes +throughout the connection. (source and destination address, port numbers etc.) +OsmoSGSN implements a TCP/IP header compression scheme called RFC1144, also +known as SLHC. This type of header compression removes the TCP/IP header +entirely and replaces it with a shorter version, that only contains the +information that is absolutely necessary to identify and check the packet. +The receiving part then restores the original header and forwards it to higher +layers. + +*compression rfc1144 passive*:: +TCP/IP header compression has to be actively requested by the modem.

The SGSN plays a similar +central function to the GPRS network as the MSC plays in the GSM +network. + +The SGSN is connected on the downlink side to Gb interfaces of the BSS, +specifically the PCU inside the BSS. The SGSN is further connected by +the GTP protocol to the GGSN which terminates the tunnels towards the +external packet data network (e.g. IPv4). + +OsmoSGSN supports both a PCU that is co-located with(in) the BTS, as +well as a PCU that is co-located with(in) the BSC. In combination with +OsmoNITB/OsmoBSC/OsmoBTS, the PCU is co-located within the BTS. + +[[fig-gprs-pcubts]] +.GPRS network architecture with PCU in BTS +[graphviz] +---- +digraph G { + rankdir=LR; + MS0 [label="MS"]; + MS1 [label="MS"]; + MS0->BTS [label="Um"]; + MS1->BTS [label="Um"]; + BTS->BSC [label="Abis"]; + BSC->MSC [label="A"]; + BTS->PCU [label="pcu_sock"]; + PCU->SGSN [label="Gb"]; + SGSN->GGSN [label="GTP"]; +} +---- + +=== Software Components + +OsmoSGSN contains a variety of different software components, which +we'll quickly describe in this section. + +==== Gb Implementation + +OsmoSGSN implements the ETSI/3GPP specified Gb interface, including TS +08.16 (NS), TS 08.18 (BSSGP) and TS 08.64 (LLC) protocols. As transport +layers for NS, it supports NS/IP (NS encapsulated in UDP/IP), as well as +NS/FR/GRE/IP. The latter is provided in order to use a Router with +Ethernet and Frame Relay interface to convert to actual physical Frame +Relay medium, which is not directly supported by OsmoSGSN. + +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 osmo-pcu, osmo-gbproxy as well as +OsmoSGSN. + + +==== GTP Implementation + +OsmoSGSN uses the libgtp implementation originating from OsmoGGSN. It +supports both GTPv0 and GTPv1. + + +==== GMM Implementation + +The GPRS Mobility Management implementation is quite simplistic at this +point. It supports the GPRS ATTACH and GPRS ROUTING AREA UPDATE +procedures, as well as GPRS ATTACH and GPRS DETACH. + +==== LLC Implementation + +The LLC (Logical Link Control) implementation of OsmoSGSN only supports +non-acknowledged mode, as this is the most common use case in real-world +GPRS networks. + +It does support both TCP/IP header compression according to RFC1144 and +payload compression according to V.42bis + +The LLC implementation does support LLC encryption with ciphers GEA3 and GEA4. +For encryption to work the auth policy needs to be set to remote and the SGSN +connected to an HLR containing the subscriber data including key material. +Other auth policys will not work with encryption. + +==== Session Management Implementation + +The session management procedures ACTIVATE PDP CONTEXT and DEACTIVATE +PDP CONTEXT are supported. However, no MODIFY PDP CONTEXT and no +Network-initiated PDP context activation is possible. This is again +covering the predominant use cases and configurations in GPRS real-world +networks while skipping the more esoteric features. + +Multiple PDP contexts can be attached by a single MS. + +Multiple GGSNs can be configured and routing to a GGSN can be configured based +on APN. Dynamic lookup of GGSNs though DNS-based APN resolving is also possible. + +=== Limitations + +At the time of writing, OsmoSGSN still has a number of limitations, +which are a result of the demand-driven Open Source development model. +If you require any of those features, please consider implementing and +contributing them, or contracting the existing OsmoSGSN developers for +performing that work. + +Known Limitations include: + +* No paging coordination between SGSN and MSC +* No SMS over Ps support diff --git a/doc/manuals/chapters/running.adoc b/doc/manuals/chapters/running.adoc new file mode 100644 index 000000000..63c2b2781 --- /dev/null +++ b/doc/manuals/chapters/running.adoc @@ -0,0 +1,35 @@ +== Running OsmoSGSN + +The OsmoSGSN executable (`osmo-sgsn`) offers the following command-line +options: + + +=== SYNOPSIS + +*osmo-sgsn* [-h|-V] [-d 'DBGMASK'] [-D] [-c 'CONFIGFILE'] [-s] [-e 'LOGLEVEL'] + + +=== OPTIONS + +*-h, --help*:: + Print a short help message about the supported options +*-V, --version*:: + Print the compile-time version number of the OsmoSGSN program +*-d, --debug 'DBGMASK','DBGLEVELS'*:: + Set the log subsystems and levels for logging to stderr.
