A method of handling location service for a network in a wireless communication system is disclosed. The method comprises transmitting a message including positioning support information of the network via a first RAT to a mobile device in the wireless communication system, for informing the mobile device whether positioning is supported in the first RAT, wherein the positioning support information indicates whether positioning is supported in the first RAT.
This application is a divisional application of U.S. application Ser. No. 12/832,081, filed on Jul. 8, 2010, which claims the benefit of U.S. Provisional Application No. 61/224,062, field on Jul. 9, 2009 and entitled “Methods for initiating location services in wireless communications system” the contents of which are incorporated herein.
A method of handling location service in a wireless communication system is disclosed to solve the above-mentioned problems.
A communication device for handling location service, utilized in a network in a wireless communication system, is disclosed. The communication device comprises a computer readable recording medium for storing program code corresponding to a process; and a processor coupled to the computer readable recording medium, for processing the program code to execute the process. The process comprises transmitting a message including positioning support information of the network via a first RAT to a mobile device in the wireless communication system, for informing the mobile device whether positioning is supported in the first RAT, wherein the positioning support information indicates whether positioning is supported in the first RAT.
In addition, the network transmits the positioning support information to the UE by the first message. The first message may be a radio resource control (RRC) message or a non-access stratum (NAS) message. The RRC message may be a broadcast control channel (BCCH) message (i.e. system information) or a dedicated message (e.g. RRCConnectionSetup message). The NAS message may be an ATTACH ACCEPT message, location area update (LAU) ACCEPT message, routing area update (RAU) ACCEPT message or a tracking area update (TAU) ACCEPT message. Those messages are examples and not intend to limit the scope.
Take an example based on the concept of the process 70. Assume the first RAT is LTE RAT and the second RAT is UMTS RAT. When the network wants to initiate the MT-LR/NI-LR, the network firstly sends a second message to request the mobile device for the positioning capability information (e.g. supported positioning methods) before the first message is received. The second message may be a LPP Capability request message, so that the UE responds the LPP Capability request message with the LPP Capability indication message including the positioning capability information to the network. After the network receives the LPP Capability indication message including the positioning capability information, the network initiates the MT-LR/NI-LR to the UE in the LTE when the positioning capability information indicates that the UE supports the LPP, and initiates the MT-LR/NI-LR to the UE in the UMTS by the CS fallback procedure when the positioning capability information indicates that the UE does not support the LPP
According to the process 80, the network requests the UE for the positioning capability information in the first RAT, and determines whether to initiate the location service in the second RAT according to the positioning capability information. For example, the network initiates the location service in the second RAT when the positioning capability information indicates that the UE supports the location service. In addition, the network stops to initiate the location service when the positioning capability information indicates that the UE does not supports the location service.
Please note that, the network may request the UE for the positioning capability information before or after the UE is handover which is triggered by the CS fallback for the location service. For example, the UE knows whether the LTE RAT supports the location service or not according to a RRC connection established with the LTE network. Therefore, the UE initiates the CS fallback procedure for initiating the location service in the UMTS RAT when the LTE RAT does not support the location service. If the network requests the UE for the positioning capability information before the UE is handover to the UMTS, namely the network requests the UE for the positioning capability information in the LTE, the UE may not be handover to the UMTS when the positioning capability information indicates that the UE does not supports the location service. Alternatively, the network may request the UE for the positioning capability after the UE is handover to the UMTS, namely the network request the UE for the positioning capability information in the UMTS. Thus, the UE does not perform the location service in the UMTS when the positioning capability information indicates that the UE does not support the location service.
Alternatively, the network may request the UE for the positioning capability information after the UE is handover to the UMTS. In this situation, the network sends a CLASSMARK ENQUIRY message to the UE for positioning capability information request, and the UE responds the CLASSMARK ENQUIRY message with a CLASSMARK CHANGE message including the positioning capability information to the network. After the network receives the CLASSMARK CHANGE message, the network initiates the location service in the UMTS RAT if the positioning capability information indicates that the UE supports the location service. In addition, the network stops to initiate the location service when the positioning capability information indicates that the UE does not support the location service, so as to avoid resource waste.
