Looping protection for copy forward SMS subscribers

A system comprising:

• a first message service center (MSC) and a second MSC,
• wherein the first MSC is configured to:
• receive, through a wireless communication network, a short message service (SMS) message,
• deliver, through the wireless communication network, the received SMS message to a first mobile device identified as a destination for the received SMS message,
• identify a copy indication to send a copy of the received SMS message to a second mobile device,
• replace a teleservice type identifier in a teleservice space of the received SMS message with a message copy indicator based on a predetermined mapping between the teleservice type identifier and the message copy indicator, responsive to identifying the copy indication, to form a modified SMS message, and
• send, through the wireless communication network, the modified SMS message to the second MSC associated with the second mobile device,
• wherein the second MSC is configured to determine whether the modified SMS message is enabled for copying, by detecting the message copy indicator in the teleservice space of the modified SMS message, and
• wherein the predetermined mapping maps a plurality of teleservice type identifiers for different teleservice types and maps each teleservice type identifier to at least one corresponding message copy indicator.

A non-transitory computer readable medium that stores instructions in at least one storage device executable by one or more network devices to cause the one or more network devices to perform functions, including functions to:

• receive, through a wireless communication network, a short message service (SMS) message,
• deliver, through the wireless communication network, the received SMS message to a first mobile device identified as a destination for the received SMS message,
• identify a copy indication for sending a copy of the received SMS message to a second mobile device,
• replace a teleservice type identifier in a teleservice space of the received SMS message with a message copy indicator based on a predetermined mapping, stored in a database, between the teleservice type identifier and the message copy indicator, responsive to identifying the copy indication, to form a modified SMS message, and
• send, through the wireless communication network, the modified SMS message to a network device associated with the second mobile device,
• wherein it is determined, by the network device associated with the second mobile device, whether the modified SMS message is enabled for copying, by detecting the message copy indicator in the teleservice space of the modified SMS message, and
• wherein the predetermined mapping maps a plurality of teleservice type identifiers for different teleservice types and maps each teleservice type identifier to at least one corresponding message copy indicator.
