Table 2
Table 2 is depicted as to Serving cell among Fig. 3 and is divided into trizonal situation, adopts the bitmap mode to identify the covering indication information.To three subregions, adopt 3 bits to identify, the corresponding overlay area of each bit in this execution mode, is expressed as effective covering with 1, and 0 is expressed as invalid covering, certainly, also can effectively cover the invalid covering of 1 expression with 0 expression.For example: the covering indication information of adjacent area 1 is 100, representes that then adjacent area 1 covers the regional A of Serving cell; Adjacent area 2 region covered are 010, represent that then adjacent area 2 covers the area B of Serving cell; The covering indication information of adjacent area 3 is 001, and sign adjacent area 3 covers the zone C of Serving cell.In a word, represent to cover in the execution mode of indication information in the bitmap mode, Serving cell is divided into N zone, then adopts N position bit to represent the coverage condition of adjacent area in each zone.
When Serving cell uses directional antenna, can adopt the directional beam of directional antenna to indicate the coverage condition of the adjacent area of Serving cell, at this moment, can confirm the division of Serving cell overlay area according to the overlay area of directional antenna in the Serving cell.As as 3 directional antennas, each antenna covers 1/3rd of whole Serving cell, then can this Serving cell be divided into three parts; A directional beam is all arranged in each zone that Serving cell is divided; In the Serving cell subregion as shown in Figure 3,1 of adjacent area occurs in the directional beam of pointing to regional A, and 2 of adjacent areas occur in the directional beam of pointing to area B; 3 of adjacent areas occur in the directional beam of pointing to zone C; The information in the Neighboring Cell List of Serving cell then, perhaps the information in all separately Neighboring Cell List of each directional antenna is indicated the coverage condition of adjacent area to the directional beam institute overlay area of each directional antenna.In the coverage of each directional antenna, also can be divided into different zones, and employing is enumerated or the mode of bitmap is indicated the indication of adjacent area to the coverage condition of this scope according to actual demands such as the network plannings.
Further, behind the list information that has obtained the Serving cell adjacent area, the terminal can further be operated, and therefore, this execution mode can comprise step 203.
Step 203: effective adjacent area is selected according to the coverage condition of the adjacent area of Serving cell in the terminal, carries out cell measurement.
In Serving cell compartment model as shown in Figure 3, if at regional A a terminal is arranged, then at this moment; The terminal can be learnt through the covering indication information in the Neighboring Cell List of Serving cell or through the directional antenna of Serving cell; In three adjacent areas of this Serving cell, adjacent area 1 is effectively to cover in regional A, and adjacent area 2 does not have overlay area A with adjacent area 3; Therefore, cell measurement and assessment are only carried out to adjacent area 1 in the terminal among the A of this zone.If this terminal is in idle condition, the terminal can be measured adjacent area 1, and when situation such as resident appearred being not enough to maintain in Serving cell, if the quality of the wireless status of adjacent area 1 meets the resident condition at terminal, then cell selecting or district reselecting were carried out in this terminal; If this terminal is in state of activation; The terminal is measured adjacent area 1; When Serving cell wireless status occurred and is not enough to maintain professional continuity, QoS requirement or network and carries out situation such as load control, if satisfy the required condition in terminal, then the terminal was carried out the sub-district and is switched.
In this execution mode, the overlay area of Serving cell is divided into different zones, the covering indication information through the adjacent area or the directional antenna of Serving cell are indicated effective coverage condition of the adjacent area of this Serving cell.Then when cell selecting, district reselecting or sub-district switching need be carried out in the terminal that exists in the Serving cell; Can be according to effective coverage condition of the Serving cell adjacent area that obtains; Cell measurement is carried out in the adjacent area of only selecting to cover this terminal, if this adjacent area meets the condition that cell selecting, gravity treatment or switching are carried out in the terminal, then selection, gravity treatment or the switching of sub-district can be carried out in the terminal; Reduced the load of nearby region measurement; Network system need not produce the idling cycle that is used for invalid nearby region measurement, prevents the too much buffer memory of user data, has guaranteed the complexity of system effectiveness and reduction scheduling and network.According to the technical scheme that provides in this execution mode; Can avoid in the scheme of prior art; Do not distinguish whether all adjacent areas all cover the terminal, and make the terminal all measure and assess, avoid dispatching the measurement that unnecessary idling cycle is carried out invalid adjacent area the adjacent area of all Serving cells; Thereby cause the reduction of system effectiveness and the deterioration of QoS, further cause the complicated problem of scheduling of resource and network; Simultaneously,, make the terminal avoid measurement, can reduce the energy consumption at terminal invalid adjacent area according to the technical scheme that provides in this execution mode.
