Abstract
The invention discloses a method for reselecting a cell, a terminal and a system. The method comprises the following steps: receiving a measurement control message sent by a network, wherein the message carries cell information for banning access; establishing a reselection list of a 3G cell and a list of cells which are banned from accessing according to the message, or establishing a reselection list of a group 3G cell and the list of the cells which are banned from accessing according to the message; and reselecting the cell according to the reselection list of the 3G cell and the list of the cells which are banned from accessing, or reselecting the cell according to the reselection list of the group 3G cell and the list of the cells which are banned from accessing. The technical proposal of the invention can prevent the access of the cells which are banned from accessing the terminal in the process of reselecting the cell, thereby reducing the time lag in the process of reselecting the cell.
Description
Technical field
The present invention relates to wireless communication technology field, especially relate to a kind of method of cell reselection, terminal and system.
Background technology
When terminal quarters at GSM EDGE Radio Access Network (GSM/EDGE Radio AccessNetwork, GERAN) in the time of in, can set up 3G sub-district reselection list (3G Cell Reselection list) or set up grouping 3G sub-district reselection list (GPRS 3G Cell Reselection list), to be used for the gravity treatment of the adjacent sub-district of 3G.Frequency, scrambler and the bandwidth information that can include the 3G sub-district in the described tabulation also can only comprise frequency point information.And in 3G network, have many different sub-districts under the same frequency, these different sub-districts are distinguished according to parameters such as scrambler and bandwidth, so in 3G sub-district reselection list or grouping 3G sub-district reselection list, only provide under the situation of frequency point information, when carrying out the sub-district gravity treatment, terminal can be selected all sub-districts under this frequency.
In cell reselection process, for the adjacent sub-district of GERAN, may include the parameter that influences the sub-district gravity treatment in the broadcast message of cell-of-origin, if these parameters are not broadcasted, terminal will solve Broadcast Control Channel (Broadcast Control Channel in the cell measurement process, BCCH) broadcast message to obtain to influence the relevant parameter of sub-district gravity treatment, is then abandoned the selection to this sub-district when finding that the sub-district is under an embargo access.For Universal Terrestrial Radio Access Network (Universal Terrestrial Radio Access Network, UTRAN) adjacent sub-district, then after selecting the sub-district, remove to solve BCCH or Packet Broadcast Control CHannel (PacketBroadcast Control Channel again, PBCCH) broadcast message inserts then withdraws from this sub-district and carry out cell reselection process again if find that the sub-district is under an embargo.In this case, if there is data service, then can cause the interruption of service short time.Universal Terrestrial Radio Access Network (Evolved UniversalTerrestrial Radio Access Network for evolution, E-UTRAN) adjacent sub-district, similar with the method for salary distribution of UTRAN sub-district, have a plurality of sub-districts under the same frequency, the sub-district under the same frequency is distinguished according to Physical Cell Identifier (physical cell id).So along with the introducing of E-UTRAN network, in carrying out cell reselection process, can occur equally terminal may select to the situation of all sub-districts under the frequency.
The inventor finds in realizing process of the present invention, when terminal quarters in the GERAN network, and when carrying out the sub-district gravity treatment according to 3G Cell Reselection list or grouping 3G Cell Reselection list, because the frequency point information of sub-district may only be provided in 3G Reselection Cell list or grouping 3G Cell Reselection list, this moment, terminal can be selected all sub-districts under this frequency, and in these sub-districts, the access that may be under an embargo of some sub-district, so when terminal selected this sub-district and decode BCCH or PBCCH broadcast message after, can forbid inserting in this sub-district of discovery, then need carry out cell reselection process again, thereby increased the time that the sub-district gravity treatment is spent, when data service is arranged, can cause the service disruption of short time.

The specific implementation process and the description among the embodiment 1 to 5 of network in the present embodiment and terminal are basic identical, no longer describe in detail herein.
By technique scheme as can be seen, forbid the cell information that inserts by in measuring control messages, carrying, make terminal can set up the cell list that 3G Cell Reselection list shows and forbids inserting, can carry out the sub-district gravity treatment with the information that the cell list of forbidding inserting provides according to 3G cell Reselection list, thereby the sub-district of forbidding inserting is not measured, can gravity treatment yet to the sub-district of forbidding inserting, thereby can reduce the time delay in the cell reselection process, avoid choosing the interruption of the service that inappropriate sub-district causes.
Forbid the cell information that inserts by in measuring control messages, carrying, also can make terminal set up the cell list that GPRS 3G cell Reselection list shows and forbids inserting, can carry out the sub-district gravity treatment with the information that the cell list of forbidding inserting provides according to GPRS 3G cellReselection list, thereby the sub-district of forbidding inserting is not measured, can gravity treatment yet to the sub-district of forbidding inserting, thereby can reduce the time delay in the cell reselection process, avoid choosing the interruption of the service that inappropriate sub-district causes.
Obviously, those skilled in the art can carry out various changes and modification to the present invention and not break away from the spirit and scope of the present invention.Like this, if of the present invention these are revised and modification belongs within the scope of claim of the present invention and equivalent technologies thereof, then the present invention also is intended to comprise these changes and modification interior.
