Description
Technical field
The present invention relates to moving communicating field, be meant a kind of processing method and device, portable terminal of cell list especially.
Background technology
Along with the continuous development of mobile communication technology, portable terminal has been deep in the middle of people's the life, and mobile communication has also become the most widely used communication mode.Alleged portable terminal specifically refers to the small hand-held formula mobile communication equipment that mobile phone, PDA (Personal Digital Assistant, palmtop PC) etc. have wireless communication function among this paper.With the mobile phone is example, and mobile phone occupies an important position in user's life as the instrument of daily life and business.Rely on the value-added service of mobile communication simultaneously, make portable terminal obtain development further.
At present the GSM of main flow all is based on development on the basis of cellular system and comes; Its channeling has improved frequency efficiency greatly and has increased power system capacity; But what bring is the service range in order to extend one's service thereupon, just must realize transregional switching.The prerequisite of transregional switching is UE (user terminal) need know the sub-district of being switched before switching a concrete condition, and UE just needs a cell list of preserving adjacent cell so, and this cell list is being stored the information of these sub-districts.
These cell informations are from the system message of network side, to obtain, and network sends to UE with these cell informations, and UE obtains the information of these sub-districts, like sub-district ID, cell information value etc.Neighbor cell list under idle pulley comes from SIB11 (system message 11).The adjacent cell information of carrying in the system message of UE through the reception Web broadcast is formed the neighbor cell list of this Serving cell, the i.e. cell list of UE.UE is according to the reception parameter S x of Serving cell itself and the system parameters Sintrasearch of network side for the selection of cell list to be measured; Sintersearch comes common decision; If i.e. Sx≤Sintrasearch; UE must carry out the measurement of co-frequency cell, otherwise then needn't carry out (if there is not parameter S intrasearch among the SI, so also must carry out the measurement of co-frequency cell); If Sx≤Sintersearch, UE must carry out the measurement of alien-frequency district, otherwise then needn't carry out (if there is not parameter S intersearch among the SI, so also must carry out the measurement of alien-frequency district).No matter be the measurement of which kind of type, all must comprise Serving cell, specifically can be with reference to 3GPP TS25.304.
In order to guarantee carrying out smoothly of switching cell, UE need measure these sub-districts, measures the signal quality of these sub-districts, so that select proper cell to carry out resident.After confirming measuring object; The RRC of portable terminal (Radio Resource Control; Radio resource control) module is sent measuring command and is given lower floor; Require physical layer that periodic P-CCPCH (Primary Common Control Physical Channel) RSCP (Received Signal Code Power, received signal code power) is carried out in sub-district to be measured and measure (under idle pulley, only carrying out RSCP measures), and give RRC reporting measuring result.After RRC obtains the measured value of sub-district to be measured, just can judge the trigger condition of district reselecting.The core content of gravity treatment trigger condition is exactly: have than the better sub-district of Serving cell, and better sub-district all keeps best in a period of time.Its inherent connotation is exactly that the UE gravity treatment of trying one's best is gone to better sub-district, but guarantees certain stability again, avoids frequent gravity treatment concussion.And the concrete standard of better sub-district has two: the one, and this adjacent cell satisfies the resident condition in sub-district (Sx＞0); The 2nd, the priority Rn of this sub-district is greater than the priority Rs of Serving cell.In concrete realization,, then descending is carried out according to Rn in these better sub-districts, as the sub-district in the reselection list when the existence of having found to have better sub-district through calculating.Then, whether RRC can keep best with regard to first sub-district (also being present best cell) that the gravity treatment timer Treselect that needs a design of unlatching monitors in the re-selecting cell tabulation in a period of time.When timer overflows, it is best that this sub-district keeps always, then successfully found best cell, starts cell reselection process, resident again to this best cell; And if before timer overflowed, change had taken place to judge best cell through the measured value of new reception, then restart timer, then the new best cell of monitoring.
But the gravity treatment under the idle pulley has a kind of special situation; (the unexpected bar of network does not fall Serving cell exactly when the various reasons Serving cell does not satisfy resident condition; Perhaps find Sx＜=0 of Serving cell in a period of time) through test; Then will trigger gravity treatment immediately, and select a best sub-district resident according to existing measured value.If also do not open gravity treatment timer Treselect in this case, just needn't open it again; Even and opened, also should cut off this timer immediately.
From above-mentioned description, can find out; UE can switch to than the better sub-district of Serving cell according to measurement result when switching, and the purpose sub-district of switching possibly be a co-frequency cell; Also possibly be alien-frequency district or different system cell; If UE switches to alien-frequency district or different system cell, the probability of handoff failure is bigger, will cause UE can not keep effectively and being connected of communication network.

Fig. 3 is the structural representation of portable terminal, and is as shown in Figure 3, and portable terminal includes 3 layer protocol stack modules, and layer 1 is exactly a physical layer; Layer 2 comprises MAC (Media Access Control, FDDI sublayer protocol) module and RLC (Radio Link Control, wireless chain control layer agreement) module; RRC (Radio Resource Control, radio resource control) module is controlled low layer as layer 3, sets up and safeguard cell list.
The cell list structure chart that Fig. 4 preserves for RRC; Behind the mobile terminal to reside cell; Receive the system messages such as SIB11 of Serving cell; RRC is set up cell list according to the adjacent cell information in the system message: the first step, from Intra-frequency measurement system information, obtain co-frequency cell information, and cell list is set up in these sub-districts of sorting; Second step obtained different frequency cell information from Inter-frequency measurement system information, cell list is set up in these sub-districts of sorting; At last, from Inter-RAT measurement system information, obtain different system cell information, cell list is set up in these sub-districts of sorting.Here Serving cell is come the end of cell list, the benefit of doing like this is that if open cell reselection process, even the gravity treatment failure, it is resident that portable terminal can also return current Serving cell as early as possible.
Fig. 5 mainly is divided into two steps for RRC is optimized the process of processing to the sub-district in the cell list:
The first step, RRC gives low layer with the cell information sending in the cell list, and low layer carries out the signal measurement of sub-district according to cell information.After RRC sets up cell list, issue the measuring task to the sub-district in the cell list, by MAC information such as the frequency of sub-district, ID are issued L1, L1 arranges to measure according to idle task, and in official hour the measurement result of reporting subdistrict.Here elder generation issues the task of co-frequency cell, issues the task of alien-frequency district afterwards again, issues the measuring task of different system cell at last again.Do not have alien-frequency district if exist, perhaps do not have the situation of different system cell, can not initiate this measuring task of two kinds so;
In second step, low layer is given RRC with reporting measuring result, and RRC sorts to the sub-district in the cell list according to measurement result; Principle is exactly according to cell measurement results (such as signal strength signal intensity) from high to low; In cell list from down and on ordering, portable terminal is that the below from cell list begins to select when carrying out cell selecting; When ordering just can guarantee that portable terminal carries out cell selecting like this, preferentially choose on the better sub-district.In the process of ordering, keep co-frequency cell, alien-frequency district, different system cell to separate such formation, such benefit is to accomplish the switching of co-frequency cell as far as possible, reduces the mortality that when alien frequencies switches, and reduces different system and switches the probability that occurs.If RRC finds to be positioned at the cell list top according to measurement result some sub-district is better than the sub-district that is positioned at the cell list below; The signal strength signal intensity of these sub-districts is higher than the sub-district that is positioned at the cell list below in other words, and RRC resequences these sub-districts in cell list so; If the situation that the sub-district that comes the cell list below before existing differs from than the sub-district that comes above the cell list in up-to-date measurement result, RRC resequences these sub-districts so, and it is come the top of cell list.
In the process of optimization process cell list, abnormal conditions may appear, such as RRC when receiving up-to-date system message; Resolve the back and find have the sub-district not allow access, indicate in Cell Barred that promptly this sub-district is to be under an embargo, if this sub-district is under an embargo; And this sub-district is in cell list; So as shown in Figure 6, RRC removes this sub-district from cell list, and the sub-district that will be on this sub-district moves down; Keep the formation in the cell list, guarantee that the sub-district in the cell list all is available sub-district.
If RRC obtains new cell information in new system message, as shown in Figure 7, RRC will carry out different operation according to new cell information this moment:
(1) new sub-district is the sub-district that can not insert, and RRC will directly abandon the information of this sub-district so, can this cell information be placed in the cell list.
(2) new sub-district is the sub-district that can insert; RRC will place according to the cell type of this sub-district so: if co-frequency cell, RRC is placed on the bottom of co-frequency cell with this sub-district, and mark does not have metrical information; The measuring task of co-frequency cell is handed down to low layer; Require low layer in idle task, to insert measuring task, measurement result is offered RRC as early as possible, RRC sorts according to the measurement result of each sub-district more then; Sort method is the same with mode shown in Figure 5, here no longer narration; If alien-frequency district, RRC is placed on the bottom of alien-frequency district with this sub-district, and asks the reporting measuring result of low layer with alien-frequency district, here the unanimity of front face; If different system cell, then the sub-district is placed on the bottom of different system cell, and is sorted in the sub-district of different system according to measurement result, no longer detail here.
(3) new sub-district is the sub-district that can insert, but this moment, cell list did not have the position to preserve new sub-district, in this case; RRC will temporarily store this cell information, earlier new sub-district measured, after the measurement of wait low layer finishes; The reporting measurement result; Cell measurement results in the measurement result of this sub-district and the cell list of the same type is compared, compare successively, if any in the sub-district of the same type of the measurement result of this sub-district in being superior to tabulating according to from high to low order; RRC is with the poorest cell information in the sub-district of the same type in the delete list so; New cell information is placed in the cell list, and is placed in the suitable formation, promptly sorted in sub-district of the same type and this sub-district according to measurement result.If this sub-district is worse than the sub-district of the same type in the tabulation, RRC abandons the information of this sub-district so, can not be placed in the cell list.
Many functional parts described in this specification all are called as module, so that stress the independence of its implementation more especially.
In the embodiment of the invention, module can realize with software, so that carried out by various types of processors.For instance, the executable code module of a sign can comprise the one or more physics or the logical block of computer instruction, and for instance, it can be built as object, process or function.However, the executable code of institute's identification module need not to be physically located in together, but can comprise the different instruction on being stored in the coordination not, when combining on these command logics, and its composition module and realize the regulation purpose of this module.
