Background technology
Along with the high speed development of the communication technology and user to the raising that communication quality and data traffic speed require, LTE (Long Term Evolution, the Long Term Evolution) network of high-speed data service service has appearred providing.Along with the LTE development of internet technology, LTE network and 2G/3G (2 can appear in communication network
NdGeneration/3
RdGeneration, second generation mobile communication technology/3G (Third Generation) Moblie technology) network and the phenomenon of depositing.
In order to realize level and smooth the moving between LTE network and the 2G/3G network, the 2G/3G network must be upgraded, to realize can switching gravity treatment and other mobile management with the LTE network.When the most basic requirement of the upgrading of 2G/3G network issues adjacent cell list information exactly in the 2G/3G network, must increase the LTE information of adjacent cells in the identical coverage, so that portable terminal also can be measured the adjacent sub-district of LTE when measuring adjacent sub-district, when the adjacent cell signal quality of LTE met the demands, portable terminal can switch or the LTE network is arrived in gravity treatment.In order to support the LTE network, portable terminal also is necessary for the highest version portable terminal after the upgrading.
The situation that in real network, may have the incompatible version of network and portable terminal, for example support the highest version portable terminal of LTE to be in the lowest version 2G/3G network of not upgrading, though in this network coverage, also be coated with the LTE network, but because when portable terminal quarters in the 2G/3G network of lowest version, do not comprise the LTE cell information in the adjacent cell list information that network side issues, so portable terminal can't be measured and move in the LTE network the LTE sub-district, promptly can not realize level and smooth moving between 2G/3G network and the LTE network.Portable terminal herein or highest version portable terminal are meant supports Release 8 versions or Release 8 portable terminal of version later on, can support the priority reselection algorithm.
Because the LTE network has data service ability at a high speed, portable terminal with LTE network contraction ability wishes to carry out data service in the LTE network, and owing to the 2G/3G network of lowest version can not carry out alternately with the LTE network, so caused the portable terminal of the highest version in the 2G/3G network that quarters at lowest version in the 2G/3G network, to switch or the sub-district gravity treatment, and can not move to LTE network operation business.Under other border, though network also is a highest version, there is different requirements in different operators, the highest version though the network that for example has has been upgraded during the cloth office network, but this operator does not support LTE or other network, so can not comprise LTE adjacent cell list information when issuing information of adjacent cells yet.In this case, though the LTE network coverage is arranged, portable terminal also can't move in the LTE network.
Described in the present invention portable terminal support but the unsupported network of Access Network of being stationed are meant, portable terminal has this Access Network ability, but can not intercommunication between the Access Network that portable terminal is stationed and this network, the sub-district that does not promptly comprise this network in the adjacent cell list that in the Access Network that portable terminal is stationed, issues, quarter at as portable terminal in the GERAN network of lowest version, with the in addition LTE network of GERAN network with covering, because the GERAN network version is lower, so the GERAN network does not comprise the cell information of LTE network when portable terminal issues adjacent cell list information, thereby portable terminal can not be from the GERAN network of being stationed by gravity treatment, switch, or the redirected LTE network that moves to.The network that and for example has two different operators to manage is respectively GERAN network highest version (or other networks) and LTE network (or other networks), these two network coverages are in identical zone, when portable terminal quarters at the GERAN network (Release 8 or later version) of highest version, owing to do not have mutual mobility protocol between these two operators, so in highest version GERAN network, when portable terminal issues information of adjacent cells, can not issue the cell information of the LTE network under another operator yet.So this moment, portable terminal can not be from the GERAN network of the highest version of being stationed by gravity treatment, switching or be redirected and move to the LTE network.
