Background technology
Mobile location service in the Radio Network System more and more is subject to extensive concern, and it is mainly used and comprises: be used for the design of location trackings, individual positioning service (inquiry of the information such as the service industry such as traffic, lodging), intelligent transport location, Radio Network System of the emergency calling position service of user security, relevant criminal activity and resource management, for the charging (determining the communication cost of some position according to calling rate) of Radio Network System etc.
3G (Third Generation) Moblie tissue (3GPP, 3rd Generation Partnership Project) the network assistance method (being also referred to as UE assisted localization method) of definition refers to: network sends auxiliary data to portable terminal, portable terminal is carried out location survey, and will send to network side with the measurement report of measurement result information, finally position a kind of method of calculating at network side; And based on network method (also claiming UE based localization method) refers to: network sends auxiliary data to portable terminal, portable terminal is carried out location survey, and calculate the positional information of portable terminal according to measurement result, finally a kind of method of calculating the result who obtains and sending to by measurement report network side; The location-independent method refers to: network does not provide supplementary to portable terminal, is finished alone a kind of method of location and acquisition positioning result by portable terminal.
Because existing 3GPP agreement Uu interface definition is indefinite, thereby may make UE (User equipment, subscriber equipment) receive the location survey request of network side after, error understanding network side radio network controller (RNC, Radio Network Controller) actual content of the location survey of request UE execution, finally can not satisfy the service quality (QoS, Quality of Service) of request, cause irrational processing.
The content that the stationkeeping ability information that the UE that defines in the 3GPP agreement reports comprises is as shown in table 1, as can be seen from Table 1, the parameter relevant with the localization method of UE support has: location-independent method, AGPS, OTDOA (IPDL), enhancing cell positioning method (supporting to receive the measurement of transmission time difference type 2) etc. have clear and definite whether support location-independent method item in this ability information.
