Abstract

Abstract Communication systems and methods are provided allowing a single mode mobile terminal to support mobile assisted signal strength measurement operations in both a fixed frequency reuse based communication network and an adaptive channel allocation based communication network. Candidate base station signal strength measurements are requested by a fixed frequency reuse type network, measured by the mobile terminal and provided to the fixed frequency reuse type network which is seeking to identify a strongest signal for mobile assisted handover operations. In addition, interference signal strength measurements are requested by an adaptive channel allocation type network, measured by the mobile terminal and provided to the adaptive channel allocation type network by the mobile terminal. No redundant circuitry is required in the mobile terminal. Instead, the mobile terminal executes the same operations using the same hardware regardless of whether the requested measurement is of a candidate signal strength or an interference signal.

Claims Analysis

Total Claims: 24
Claim 1
Independent Claim 165 words
A method of operating at least a first and a second mobile telecommunications network connected through at least one common node, the first network comprising a first access network and a core network and the common node being in the core network, a mobile terminal being in radio communication with the first mobile telecommunications network, the method comprising the steps of: the mobile terminal scanning a frequency spectrum and identifying at least a potential radio access network; the mobile terminal communicating a report of the results of the scan to the first network, the mobile terminal sending a message to the first telecommunications network with a request for specific mobile telecommunications service, the first network deciding in response to the report and the request which of the radio networks detected by the scan of the mobile terminal is suitable for the requested service, and the first radio network requesting the common node to redirect at least a part of the communication to the second network.
Claim 2
Independent Claim 165 words
A method of operating at least a first and a second mobile telecommunications network connected through at least one common node, the first network comprising a first access network and a core network and the common node being in the core network, a mobile terminal being in radio communication with the first mobile telecommunications network, the method comprising the steps of: the mobile terminal scanning a frequency spectrum and identifying at least a potential radio access network; the mobile terminal communicating a report of the results of the scan to the first network, the mobile terminal sending a message to the first telecommunications network with a request for specific mobile telecommunications service, the first network deciding in response to the report and the request which of the radio networks detected by the scan of the mobile terminal is suitable for the requested service, and the first radio network requesting the common node to redirect at least a part of the communication to the second network.
Claim 3
Dependent Claim 17 words

Claim 4
Dependent Claim 27 words
The method according to claim 1 , wherein the radio access technology of the first network is different from the radio access technology of the second network.
Claim 5
Dependent Claim 31 words
The method according to claim 1 , further comprising the step of the first network transmitting a message to the mobile terminal, the message including system parameters of the second network.
Claim 6
Dependent Claim 16 words
The method according to claim 4 , wherein the message is broadcast to the mobile terminal.
Claim 7
Dependent Claim 20 words
The method according to claim 4 , wherein the message is transmitted depending upon the location of the mobile terminal.
Claim 8
Dependent Claim 14 words

Claim 11
Dependent Claim 53 words
The method according to claim 1 further comprising a Radio Network Controller (RNC) in the first network determining whether a new Radio Access Bearer (RAB) is required based on the measurement report from the mobile and, if so, requesting a new Radio Access Bearer (RAB) from the common node in the core network.
Claim 12
Dependent Claim 39 words
The method according to claim 10 further comprising the common node in the core network requesting a new bearer allocation from an inter working unit (IWU) of the second network and receiving an acknowledgement when the bearer is allocated.
Claim 13
Dependent Claim 25 words
The method according to claim 11 further comprising the common node sending a confirmation to the Radio Network Controller (RNC) when the handover is authorized.
Claim 14
Dependent Claim 38 words
The method according to claim 12 further comprising the Radio Network Controller (RNC), in response to receiving the handover authorization, sending a handover command to the mobile and the mobile beginning a log-on procedure to the second network.
Claim 15
Dependent Claim 18 words
The method according to claim 13 further comprising the common node requesting the first network to release communication.
Claim 16
