Radio system and method of control for efficient site load distribution
First Claim
1. A method of controlling a radio system, comprising:
- at the mobile station, attempting to register with a first site;
at the first site, monitoring a site loading parameter and, if the site loading parameter does not exceed a threshold, sending a first class of acknowledgment to the radio and if the site loading parameter exceeds the threshold, sending a second class of acknowledgment to the radio;
at the mobile radio station, in response to a first class of acknowledgment, treating the first site as the registered site for further communications and, in response to a second class of acknowledgment, attempting to register at a second site and if no acknowledgment is received from the second site, treating the first site as the registered site even if the site loading parameter exceeds the threshold.

Abstract
A radio system has a number of fixed transceivers (12-18) serving a number of radio coverage sites (28-34). A multisite controller (10) has a memory (42) including mobile radio station identifications and site associations, associating mobile radio station identifications with sites. A processor (40) computes a site loading parameter for each site, dependent on the resources at the site and the number of mobile radio stations associated with the site. A request is received from a mobile radio station to form a new association between the given site and the identification of the mobile radio station sending the request and a response to the request is selected dependent on the site loading parameters in the different sites. For example in response to a first class of acknowledgment, the first site is treated as the registered site and, in response to a second class of acknowledgment, an attempt is made to register at a second site and if no acknowledgment is received from the second site, the first site is treated as the registered site.

10. A radio system comprising a plurality of fixed transceivers serving a plurality of radio coverage sites and a multisite controller connected to the fixed transceivers, the multisite controller comprising:
-
a memory including mobile radio station identifications and site associations, associating mobile radio station identifications with sites at which the corresponding mobile radio stations are registered; processing means for computing a site loading parameter for each site, dependent on the resources at the site and the number of mobile radio stations associated with the site; receiving means for receiving from a given site a request from a mobile radio station to form a new association between the given site and the identification of the mobile radio station sending the request; and selection means, responsive to the processing means, for selecting a response to the request indicating one of a plurality of different classes of registration dependent on the site loading parameter in the given site and the site loading parameter in at least one adjacent site, wherein a first class of the plurality of different classes of registration is indicative of an immediate registration grant at the given site, and a second class of the plurality of different registration classes is indicative of a registration grant at the given site only if registration is unsuccessful at the at least one adjacent site.
