Could you advise on the meaning of "TCH signalling"?

Gents,

Could we use TCH for signalling ( to setup a call for example)?

Immediate assignment on TCH feature give you what you want

Thanks for your response,


a more detailled answer from E******* Basic Features R12 description:


Immediate Assignment on TCH gives the operator the possibility to define the channel allocation strategy at the immediate assignment procedure. This feature makes it possible to have faster call set up times for speech and data connections. It also allows for setting of allocation alternatives between SDCCH and TCH if blocking should occur on either resource type.When the feature TCH immediate assign is active, the priority order between assignment of a SDCCH or a TCH at Immediate assignment can be defined in the feature Channel administration, which will give the possibility to decide whether an alternative allocation isallowed.
Some examples of possible strategies that can be chosen are:
1. Immediate assignment is made either on SDCCH or on TCH, depending on the information provided by the mobile at initial access
2. Immediate assignment on TCH will be done only in situations of congestion on the SDCCH. This will give a greater flexibility in configuring cell resources for SDCCH traffic


Different immediate strategies can be chosen for different cells. This can be defined by combining Immediate Assignment on TCH strategy with the proper definition of parameters in the feature Channel Administration.
