SMPP

Since Camel 2.2

Both producer and consumer are supported

This component provides access to an SMSC (Short Message Service Center) over the SMPP protocol to send and receive SMS. The JSMPP library is used for the protocol implementation.

The Camel component currently operates as an ESME (External Short Messaging Entity) and not as an SMSC itself.

You are also able to execute ReplaceSm, QuerySm, SubmitMulti, CancelSm and DataSm.

Maven users will need to add the following dependency to their pom.xml for this component:

<dependency>
    <groupId>org.apache.camel</groupId>
    <artifactId>camel-smpp</artifactId>
    <version>x.x.x</version>
    <!-- use the same version as your Camel core version -->
</dependency>

SMS limitations

SMS is neither reliable or secure. Users who require reliable and secure delivery may want to consider using the XMPP or SIP components instead, combined with a smartphone app supporting the chosen protocol.

  • Reliability: although the SMPP standard offers a range of feedback mechanisms to indicate errors, non-delivery and confirmation of delivery it is not uncommon for mobile networks to hide or simulate these responses. For example, some networks automatically send a delivery confirmation for every message even if the destination number is invalid or not switched on. Some networks silently drop messages if they think they are spam. Spam detection rules in the network may be very crude, sometimes more than 100 messages per day from a single sender may be considered spam.

  • Security: there is basic encryption for the last hop from the radio tower down to the recipient handset. SMS messages are not encrypted or authenticated in any other part of the network. Some operators allow staff in retail outlets or call centres to browse through the SMS message histories of their customers. Message sender identity can be easily forged. Regulators and even the mobile telephone industry itself has cautioned against the use of SMS in two-factor authentication schemes and other purposes where security is important.

While the Camel component makes it as easy as possible to send messages to the SMS network, it can not offer an easy solution to these problems.

Data coding, alphabet and international character sets

Data coding and alphabet can be specified on a per-message basis. Default values can be specified for the endpoint. It is important to understand the relationship between these options and the way the component acts when more than one value is set.

Data coding is an 8 bit field in the SMPP wire format.

Alphabet corresponds to bits 0-3 of the data coding field. For some types of message, where a message class is used (by setting bit 5 of the data coding field), the lower two bits of the data coding field are not interpreted as alphabet and only bits 2 and 3 impact the alphabet.

Furthermore, current version of the JSMPP library only seems to support bits 2 and 3, assuming that bits 0 and 1 are used for message class. This is why the Alphabet class in JSMPP doesn’t support the value 3 (binary 0011) which indicates ISO-8859-1.

Although JSMPP provides a representation of the message class parameter, the Camel component doesn’t currently provide a way to set it other than manually setting the corresponding bits in the data coding field.

When setting the data coding field in the outgoing message, the Camel component considers the following values and uses the first one it can find:

  • the data coding specified in a header

  • the alphabet specified in a header

  • the data coding specified in the endpoint configuration (URI parameter)

In addition to trying to send the data coding value to the SMSC, the Camel component also tries to analyze the message body, converts it to a Java String (Unicode) and converts that to a byte array in the corresponding alphabet. When deciding which alphabet to use in the byte array, the Camel SMPP component does not consider the data coding value (header or configuration), it only considers the specified alphabet (from either the header or endpoint parameter).

If some characters in the String can not be represented in the chosen alphabet, they may be replaced by the question mark ( ? ) symbol. Users of the API may want to consider checking if their message body can be converted to ISO-8859-1 before passing it to the component and if not, setting the alphabet header to request UCS-2 encoding. If the alphabet and data coding options are not specified at all then the component may try to detect the required encoding and set the data coding for you.

The list of alphabet codes are specified in the SMPP specification v3.4, section 5.2.19. One notable limitation of the SMPP specification is that there is no alphabet code for explicitly requesting use of the GSM 3.38 (7 bit) character set. Choosing the value 0 for the alphabet selects the SMSC default alphabet, this usually means GSM 3.38 but it is not guaranteed. The SMPP gateway Nexmo actually allows the default to be mapped to any other character set with a control panel option. It is suggested that users check with their SMSC operator to confirm exactly which character set is being used as the default.

Message splitting and throttling

After transforming a message body from a String to a byte array, the Camel component is also responsible for splitting the message into parts (within the 140 byte SMS size limit) before passing it to JSMPP. This is completed automatically.

If the GSM 3.38 alphabet is used, the component will pack up to 160 characters into the 140 byte message body. If an 8 bit character set is used (e.g. ISO-8859-1 for western Europe) then 140 characters will be allowed within the 140 byte message body. If 16 bit UCS-2 encoding is used then just 70 characters fit into each 140 byte message.

Some SMSC providers implement throttling rules. Each part of a message that has been split may be counted separately by the provider’s throttling mechanism. The Camel Throttler component can be useful for throttling messages in the SMPP route before handing them to the SMSC.

URI format

smpp://[username@]hostname[:port][?options]
smpps://[username@]hostname[:port][?options]

If no username is provided, then Camel will provide the default value smppclient.
If no port number is provided, then Camel will provide the default value 2775.
If the protocol name is "smpps", camel-smpp with try to use SSLSocket to init a connection to the server.

Configuring Options

Camel components are configured on two separate levels:

  • component level

  • endpoint level

Configuring Component Options

The component level is the highest level which holds general and common configurations that are inherited by the endpoints. For example a component may have security settings, credentials for authentication, urls for network connection and so forth.

Some components only have a few options, and others may have many. Because components typically have pre configured defaults that are commonly used, then you may often only need to configure a few options on a component; or none at all.

Configuring components can be done with the Component DSL, in a configuration file (application.properties|yaml), or directly with Java code.

Configuring Endpoint Options

Where you find yourself configuring the most is on endpoints, as endpoints often have many options, which allows you to configure what you need the endpoint to do. The options are also categorized into whether the endpoint is used as consumer (from) or as a producer (to), or used for both.

Configuring endpoints is most often done directly in the endpoint URI as path and query parameters. You can also use the Endpoint DSL as a type safe way of configuring endpoints.

A good practice when configuring options is to use Property Placeholders, which allows to not hardcode urls, port numbers, sensitive information, and other settings. In other words placeholders allows to externalize the configuration from your code, and gives more flexibility and reuse.

The following two sections lists all the options, firstly for the component followed by the endpoint.

Component Options

The SMPP component supports 41 options, which are listed below.

Name Description Default Type

initialReconnectDelay (common)

Defines the initial delay in milliseconds after the consumer/producer tries to reconnect to the SMSC, after the connection was lost.

5000

long

maxReconnect (common)

Defines the maximum number of attempts to reconnect to the SMSC, if SMSC returns a negative bind response.

2147483647

int

reconnectDelay (common)

Defines the interval in milliseconds between the reconnect attempts, if the connection to the SMSC was lost and the previous was not succeed.

5000

long

splittingPolicy (common)

You can specify a policy for handling long messages: ALLOW - the default, long messages are split to 140 bytes per message TRUNCATE - long messages are split and only the first fragment will be sent to the SMSC. Some carriers drop subsequent fragments so this reduces load on the SMPP connection sending parts of a message that will never be delivered. REJECT - if a message would need to be split, it is rejected with an SMPP NegativeResponseException and the reason code signifying the message is too long.

Enum values:

  • ALLOW

  • REJECT

  • TRUNCATE

ALLOW

String

bridgeErrorHandler (consumer)

Allows for bridging the consumer to the Camel routing Error Handler, which mean any exceptions occurred while the consumer is trying to pickup incoming messages, or the likes, will now be processed as a message and handled by the routing Error Handler. By default the consumer will use the org.apache.camel.spi.ExceptionHandler to deal with exceptions, that will be logged at WARN or ERROR level and ignored.

boolean

lazyStartProducer (producer)

See the documentation of the JSMPP Library for more details about the underlying library.

Exception handling

This component supports the general Camel exception handling capabilities

When an error occurs sending a message with SubmitSm (the default action), the org.apache.camel.component.smpp.SmppException is thrown with a nested exception, org.jsmpp.extra.NegativeResponseException. Call NegativeResponseException.getCommandStatus() to obtain the exact SMPP negative response code, the values are explained in the SMPP specification 3.4, section 5.1.3.
When the SMPP consumer receives a DeliverSm or DataSm short message and the processing of these messages fails, you can also throw a ProcessRequestException instead of handle the failure. In this case, this exception is forwarded to the underlying JSMPP library which will return the included error code to the SMSC. This feature is useful to e.g. instruct the SMSC to resend the short message at a later time. This could be done with the following lines of code:

from("smpp://smppclient@localhost:2775?password=password&enquireLinkTimer=3000&transactionTimer=5000&systemType=consumer")
  .doTry()
    .to("bean:dao?method=updateSmsState")
  .doCatch(Exception.class)
    .throwException(new ProcessRequestException("update of sms state failed", 100))
  .end();

Please refer to the SMPP specification for the complete list of error codes and their meanings.
