1.1Registration

By sending a short message to a specified destination number, the subscriber can get the location based service activated for him self. Synonyms of ACTIVATE (viz. REG, REGISTER, SIGNUP, ACT) can also be used to activate this feature. Once the request Is successfully registered, the LBS system sends back a confirmatory message back to the subscriber:

1.2 Adding new buddies

New buddies can be added to a subscribers list by sending a short message like ADD Buddy-MSISDN [NickName] [GroupName]

In the above message, ADD is the command which is used for adding a new buddy. The Buddy-MSISDN is the MSISDN of the buddy/friend to be added to the list. This is a mandatory parameter in the ADD command. The NickName is the name, which is used instead of the MSISDN while displaying the Buddy List in the subscriber mobile. This is an optional parameter in the ADD command.

GroupName is the name of the group where the added MSISDN belongs. If the group is not already present it will create a new group and the new buddy will be added under this group. This is an optional parameter and the ADD command can be sent without this also. In the case that GroupName is omitted, Buddy-MSISDN wont belong to any group (default group).

After receiving the ADD command, the LBS System will send a short message to other person for confirmation.One needs to reply with an OK short message followed by MSISDN of the person who wants him to be added as a buddy. 

After receiving the confirmation message, the system will intimate the originator that the Buddy has been successfully added. The system will wait for the confirmation for a configurable period of time after which a negative response will be sent to the originator.

By sending a short message, in any of the format given below, the subscriber can delete buddies from his list.
DELETE Buddy-MSISDN
DELETE NickName
DELETE GroupName
Buddy-MSISDN or NickName will remove a particular MSISDN from the list. If the GroupName is specified, all the members in that particular group will be deleted. 

The subscriber gets a deletion confirmation once the MSISDN or group is deleted from the system. DELETE BUDDY and DEL are the other keywords that can be used in place of DELETE.
