Radio base resource allocation method and radio base station

A radio base station comprising:

• a plurality of signal processing cards for performing signal processing on communication calls in and wireless communications;
• and
• a wireless resource monitor which registers a call of a type whose loss is to be avoided as a protected calls among a plurality of types of calls, compares a first sum of a resource of the protected call and a resource of a new call with vacant resources of at least two signal processing cards when the new call occurs,
• defines a case that the first sum is more than a vacant resource of each of the signal processing card cards as a high traffic time, while defining a case that the first sum is less than or equal to a vacant resource of either signal processing card of the at least two signal processing cards as a low traffic time, and
• switches a resource allocating scheme between the high traffic time and the low traffic time.

A resource allocating method in a radio base station for allocating a plurality of types of calls to a plurality of signal processing cards, comprising the steps of:

• registering a call of a type whose loss is to be avoided as a protected call among the plurality of types of calls;
• comparing a first sum of a resource of the protected call and a resource of a new call with vacant resources of at least two signal processing cards when the new call occurs;
• and
• switching a resource allocating scheme according to a result of comparison.
