Abstract

In an integrated dispatch/interconnect commu- dispatch area while once in a while he may need to nication system such as Motorola Integrated Radio initiate or receive an interconnect call. To avoid System (MIRS) a user may be involved at commu- missed communicationsiby a mixed dispatch/inter- nication at several levels. For instance he may be connect user in an RF~:communications system a participating in a Workgroup communication over following technique can be applied.

  In the diagram mobile stations MSl, 2,3 are all members of the same talk group. If MS2 becomes involved in interconnect call the Fixed Side control- ler automatically begins logging all talk group traf- fic into the voice storage. Upon MS2 termination of the land line call, all the logged voice traffic is auto- matically or upon a command is transmitted to the MS2 on a private channel. This is especially appro- priate in digital RF communication system such as MIRS where inherently low rate voice coder is used to minimize transmission and storage requirements and where many of the services and hardware sub-

systems required are already in place to implement this feature.

All the silence between the talk spurts are deleted to produce an efftcient retrieval.
