Cell reselection is divided into intra-system cells gravity treatment and the gravity treatment of different system cell, and intra-system cells gravity treatment refers to the gravity treatment carried out in a kind of wireless access system with frequency or alien-frequency district；The gravity treatment of different system cell refers to the gravity treatment carrying out community between multiple wireless access system.When carrying out intra-system cells gravity treatment, the network type of each adjacent area of community is consistent with the network type of the current service cell of terminal, and the adjacent area of the service feature type matching of terminal, or is all adjacent areas, or is empty, it is not necessary to carry out priority adjustment.Therefore, the application scenarios of the present embodiment is mainly the cell reselection between system.
Fig. 3 is the flow chart of another embodiment of residence reselecting provided by the invention, as it is shown on figure 3, include:
301, terminal resides in LTE Serving cell.
302, terminal reads the system message of LTE Serving cell, knows the gravity treatment priority parameters (cellReselectionPriority) of each frequency in adjacent area of the homogeneous-frequency adjacent-domain of homologous ray, the alien frequencies adjacent area of homologous ray, different system.
Wherein, as shown in table 1, the gravity treatment priority parameters of the current service cell of terminal is saved in the SIB3 in system message, the gravity treatment priority parameters of LTE alien frequencies adjacent area is saved in the SIB5 in system message, the gravity treatment priority parameters of TD-SCDMA adjacent area and WCDMA adjacent area is saved in the SIB6 in system message, the gravity treatment priority parameters of GSM adjacent area is saved in the SIB7 in system message, and the gravity treatment priority parameters of CDMA2000 adjacent area is saved in the SIB8 in system message.
The distribution in system message of the table 1 gravity treatment priority parameters
303, whether terminal resolution system message provide priority adjustment instruction parameter (PriorityAdjustment), if system message does not provide PriorityAdjustment parameter, then the gravity treatment priority of each adjacent area is not adjusted, carries out step 316；If system message provides PriorityAdjustment parameter, then carry out step 304, the gravity treatment priority of each adjacent area is adjusted.
When current service cell is LTE community, priority adjustment instruction parameter may be located in cell reselection public information (cellReselectionInfoCommon) field in the system message SIB3 message blocks of LTE community, and this field comprises the public information with frequency, alien frequencies and the gravity treatment of different system cell.Current service cell by carrying PriorityAdjustment parameter in SIB3, and the gravity treatment priority of adjacent area is adjusted by notice terminal.
304, terminal checks whether the network type of each adjacent area is LTE, if the network type of all adjacent areas is all LTE, carries out step 316；Otherwise, step 305 is carried out.
305, terminal will arrange by gravity treatment priority order from high to low with the adjacent area of its service feature type matching, and will arrange by gravity treatment priority order from high to low with its unmatched adjacent area of service feature type.
Without loss of generality, it is assumed that the LTE Neighboring Cell List after sequence is designated as { A1, A2, ..., AM}, corresponding gravity treatment priority list is designated as { a1, a2 ..., aM}, non-LTE adjacent area (2G or 3G adjacent area) list after sequence be designated as B1, B2 ..., BN}, corresponding gravity treatment priority list is designated as { b1, b2, ..., bN}.Wherein, Ai represents i-th LTE adjacent area, and ai represents the gravity treatment priority of i-th LTE adjacent area Ai, and M is the number of LTE adjacent area；Bj represents the non-LTE adjacent area of jth, and bj represents the gravity treatment priority of jth non-LTE adjacent area Bj, and N is the number of non-LTE adjacent area.Wherein, ai ≠ bj, and 0≤ai≤7,0≤bj≤7,0≤i≤M, 0≤j≤N.
306, terminal checks the service feature type of self, if terminal is based on speech business, carries out step 307；If terminal is based on data service, carry out step 312.
307, the gravity treatment priority of the whether all non-LTE adjacent areas of terminal judges both is greater than the gravity treatment priority of LTE adjacent area, if the gravity treatment priority of a certain non-LTE adjacent area is less than the gravity treatment priority of LTE adjacent area, then carries out step 308, otherwise carries out step 316.
It is to say, terminal checks that whether the minima bN in non-LTE adjacent area gravity treatment priority list is more than the maximum a1 in LTE adjacent area gravity treatment priority list.
308, the minima in non-LTE adjacent area gravity treatment priority list is interchangeable by terminal with the maximum in LTE adjacent area gravity treatment priority list.
It is to say, the value of bN and a1 is exchanged, i.e. bN_new=a1, a1_new=bN, { a1, a2, ..., aM} and { b1, b2, ..., other value in bN} remains unchanged, and LTE adjacent area and the gravity treatment priority list of non-LTE adjacent area after adjustment are designated as { a1_new respectively, a2_new ..., aM_new}, { b1_new, b2_new ..., bN_new}.
309, the gravity treatment priority list of the LTE adjacent area after adjusting and non-LTE adjacent area is re-started arrangement according to gravity treatment priority order from high to low by terminal respectively.
Wherein, terminal gravity treatment priority list { a1_new, a2_new to the LTE adjacent area after adjusting and non-LTE adjacent area, ..., aM_new}, { b1_new, b2_new, ..., bN_new} re-starts arrangement by gravity treatment priority order from high to low respectively, and LTE adjacent area and the gravity treatment priority list of non-LTE adjacent area after sequence are designated as { a1, a2, ..., aM }, { b1, b2, ..., bN }.
310, whether the gravity treatment priority in the gravity treatment priority list of the non-LTE adjacent area of terminal judges both is greater than the gravity treatment priority in the gravity treatment priority list of LTE adjacent area, if so, carries out step 311；Otherwise, repeat step 308-309, until the gravity treatment priority of all non-LTE adjacent areas both is greater than the gravity treatment priority of LTE adjacent area.
311, each priority in the gravity treatment priority list of the LTE adjacent area after adjustment is sequentially allocated to LTE Neighboring Cell List Zhong Ge community in order, and be sequentially allocated each priority in the gravity treatment priority list of the non-LTE adjacent area after adjustment to non-LTE Neighboring Cell List Zhong Ge community in order, and carry out step 316.
nullWherein，After each priority of LTE adjacent area is adjusted by terminal，Terminal is by the gravity treatment priority list { a1 of the LTE adjacent area after adjustment，a2ˊ，…，AM } in each priority be sequentially allocated in order to LTE Neighboring Cell List { A1，A2，…，AM} Zhong Ge community，Gravity treatment priority list { b1 by the non-LTE adjacent area after adjustment，b2ˊ，…，BN } in each priority be sequentially allocated in order to non-LTE Neighboring Cell List { B1，B2，…，BN} Zhong Ge community，After allowing to carry out the adjustment of gravity treatment priority，The gravity treatment priority of each adjacent area of all service feature type matching with terminal both be greater than in the adjacent area of terminal current service cell except with the adjacent area of service feature type matching except the gravity treatment priority of other adjacent areas，And remain unchanged with the ranking results of the gravity treatment priority of each adjacent area of the service feature type matching of terminal，In the adjacent area of terminal current service cell except with the adjacent area of service feature type matching except the ranking results of gravity treatment priority of other adjacent areas also remain unchanged，Thus not affecting the use of operator's flow control strategy in hierarchical network.
312, the gravity treatment priority of the whether all LTE adjacent areas of terminal judges both is greater than the gravity treatment priority of non-LTE adjacent area, if the gravity treatment priority of a certain LTE adjacent area is less than non-LTE adjacent area, then carries out step 313, otherwise, carries out step 316.
That is, terminal checks that the minima aM in LTE adjacent area gravity treatment priority list is whether more than the gravity treatment priority b1 of non-LTE community.
313, the minima in LTE adjacent area gravity treatment priority list is swapped by terminal with the maximum in non-LTE adjacent area gravity treatment priority list.
That is, the value of aM and b1 is exchanged by terminal, i.e. aM_new=b1, b1_new=aM；A1, a2 ..., and aM} with b1, b2 ..., other value in bN} remains unchanged, LTE adjacent area and the gravity treatment priority list of non-LTE adjacent area after adjustment be designated as a1_new, a2_new ..., aM_new}, b1_new, b2_new ..., bN_new}.
314, the gravity treatment priority list of the LTE adjacent area after adjusting and non-LTE adjacent area is rearranged by terminal respectively by gravity treatment priority order from high to low.
Wherein, terminal gravity treatment priority list { a1_new, a2_new to the LTE adjacent area after adjusting and non-LTE adjacent area, ..., aM_new}, { b1_new, b2_new, ..., bN_new} rearranges by gravity treatment priority order from high to low respectively, and LTE adjacent area and the gravity treatment priority list of non-LTE adjacent area after sequence are designated as { a1, a2, ..., aM }, { b1, b2, ..., bN }.
315, whether the gravity treatment priority in the gravity treatment priority list of terminal judges LTE adjacent area both is greater than the gravity treatment priority in the gravity treatment priority list of non-LTE adjacent area, if so, carries out step 311；Otherwise, step 313-314 is repeated, until the gravity treatment priority of all LTE adjacent areas both is greater than the gravity treatment priority of non-LTE adjacent area.
Step 316, the terminal precedence information according to each adjacent area, the reselection strategies according to setting determines reselection target cell.
Such as, when terminal is positioned at the overlapping covered of LTE network and WCDMA network, and the current service cell of terminal is when being LTE community, terminal is by intercepting the system message that current service cell issues, SIB3 in read system message, obtain the gravity treatment priority of current service cell, i.e. cellReselectionPriority_LTE_F0=2；SIB6 in read system message, obtains the gravity treatment priority of each frequency in WCDMA adjacent area, i.e. cellReselectionPriority_nonLTE_F1=1, cellReselectionPriority_nonLTE_F2=0；Terminal is resolved to PriorityAdjustment parameter from system message SIB3；The Neighboring Cell List of current service cell CELLA configuration comprises the community CELLC on community CELLB, WCDMAF2 frequency on WCDMAF1 frequency.
Terminal is to WCDMA Neighboring Cell List by the order arrangement from high to low of gravity treatment priority, and the WCDMA Neighboring Cell List after sequence is designated as that { CELLB, CELLC}, corresponding each cell reselection priority list is designated as { 1,0}.
When the terminal in this region is with speech business for time main, owing to the minima in the gravity treatment priority list of WCDMA adjacent area is 0, less than the gravity treatment priority 2 of the LTE community, current service cell of terminal, therefore the gravity treatment priority of the minima in the gravity treatment priority list of WCDMA adjacent area with LTE community is exchanged by terminal；The gravity treatment priority list of the WCDMA adjacent area after adjustment is { 1,2}；After according to priority the gravity treatment priority list of WCDMA adjacent area is resequenced by order from high to low, the gravity treatment priority list of WCDMA adjacent area is { 2,1}；By the gravity treatment priority list of WCDMA adjacent area, { value in 2,1} is sequentially allocated to WCDMA Neighboring Cell List, and { CELLB, CELLC}, namely the gravity treatment priority that gravity treatment priority is 2, CELLC of CELLB is 1；Now the gravity treatment priority of LTE community, the current service cell CELLA of terminal is 0.Terminal can carry out cell reselection according to the gravity treatment priority parameters of each adjacent area after adjusting, so that the terminal based on speech business can preferentially reselect to WCDMA network.
When the terminal in this region is with data service for time main, owing to the gravity treatment priority of the LTE community, current service cell of terminal is 2, more than the gravity treatment priority of all WCDMA adjacent areas, so terminal is without being adjusted gravity treatment priority.
nullIn the present embodiment，By the service feature type according to terminal and adjacent area network type information，Determine at least one the target adjacent area with service feature type matching，Priority in target adjacent area lower than the adjacent area of current service cell in the priority of other adjacent areas except target adjacent area time，Improve the priority of target adjacent area，So that the priority of all target adjacent areas is higher than the priority of other adjacent areas in the adjacent area of current service cell except target adjacent area，The terminal precedence information according to the adjacent area of the current service cell after adjusting，Reselection strategies according to setting determines reselection target cell，So that terminal reselects to and the community of its service feature type matching，Namely the terminal based on speech business reselects to 2G or 3G community，Terminal based on data service reselects to LTE community，Improve the experience of user；And ensure carry out gravity treatment priority adjustment after, remain unchanged by the result of corresponding gravity treatment prioritization with each adjacent area of the service feature type matching of terminal, except other adjacent areas except the adjacent area of service feature type matching also remain unchanged by the result of corresponding gravity treatment prioritization in the adjacent area of terminal current service cell, thus not affecting the use of operator's flow control strategy in hierarchical network.Additionally, after terminal improves the priority of each target adjacent area simultaneously, if there is gravity treatment failure when initiating gravity treatment to the adjacent area that multiple target adjacent areas medium priority is the highest in terminal, then terminal can also initiate gravity treatment to the adjacent area that multiple target adjacent areas medium priority is second highest, thus improving the success rate of different system cell gravity treatment, it is ensured that terminal can reselect to and the network of its service feature type matching.
