In an overload control method for a spread spectrum communication system, when the number of mobile stations communicating with a base station is equal to or more than a predetermined number, the ratio of increase instructions to reverse link transmission power control bits transmitted to the mobile

In an overload control method for a spread spectrum communication system, when the number of mobile stations communicating with a base station is equal to or more than a predetermined number, the ratio of increase instructions to reverse link transmission power control bits transmitted to the mobile stations from the base station is measured. When the measured ratio is equal to or more than a predetermined ratio, it is determined whether the reverse link interference amount between the base station and the mobile stations is equal to or more than an allowable value. When it is determined that the reverse link interference amount is equal to or more than the allowable value, the reverse link interference amount is reduced by imposing transmission power restrictions or origination/termination restrictions.

A method of manufacturing a semiconductor laser device according to claim 17, wherein said cladding layer part of the second conductive type is formed by the steps of: laminating a GaAs etching stop layer on said upper optical waveguide layer; laminating an InGaAlP current confinement layer of the first conductive type on said second etching stop layer; laminating an InGaP cap layer of the first conductive type on said current confinement layer; laminating a second GaAs cap layer on said InGaP cap layer; removing a portion of said second GaAs cap layer corresponding to a stripe-shaped current injection opening; removing portions of said InGaP cap layer of the first conductive type and said current confinement layer, which are to be used as said current injection opening, using said second GaAs cap layer as a mask; removing said second GaAs cap layer used as the mask and simultaneously removing a portion of said GaAs etching stop layer, which is to be used as said current injection opening, using said InGaP cap layer of the first conductive type as a mask; and forming a cladding layer of the second conductive type so as to cover said current injection opening.
