When the discrimination above is made, while a call control means 14d keeps a call of the call consecutive request source, the means 14d makes a call request of the mobile communication terminal equipment to other adjacent mobile communication network and when a call with the mobile communication terminal equipment is set up accordingly, the call is connected to a call of the call consecutive request source having been stored as above.
