Key Parameter list for Hopping

Key Parameter list for Hopping, sequence number, hopping, frequency, hsn, maio, ma list, gsm, cycle hopping, MAI is the function of TDMA FN, HSN and MAIO.

When you decide to apply hopping to any BTS then below parameter require to previously defining.

  • All the parameters which are related to hopping are configured in cell/configure Hopping data
  • Hopping mode: the mode used by the BTS system, including three options: not hopping, base band hopping and RF hopping.
  • MA (Mobile Allocation Set): the set of available RF bands when hopping, containing at most 64 frequency carriers. The frequency being used must be those of the available frequency
  • HSN:hopping sequence number(0~63)
  • HSN=0:cycle hopping.
  • HSN≠0:random hopping. Every sequence  number  corresponds a pseudo random sequence.
  • MAIO (Mobile Allocation Index Offset): used to define the initial frequency of the hopping.
  • Be careful to configure the MAIO of same timeslot in all channels, otherwise interference occurs.
  • At the air interface, the frequency used on a specific burst is an element in MA set. MAI is used for indication, referring to a specific element in the MA set.
  • MAI is the function of TDMA FN, HSN and MAIO.
