Embodiment 1

[0036] This embodiment provides a method for querying a two-dimensional dynamic contact query list based on a double-hash structure. The method for querying a two-dimensional dynamic contact query list based on a double-hash structure is performed in a mobile terminal environment, and the method is executed. Mobile terminals include mobile phones, PDAs, and the like. see figure 1 , which is shown as the flow of the two-dimensional dynamic contact query method based on the double hash structure, including:

[0037] S1, constructing a contact query hash list, and storing the constructed contact query hash list in the buffer pool of the mobile terminal; the contact query hash list is composed of multiple two-dimensional tables, and multiple two-dimensional tables Stored in order of contact name. Each two-dimensional table is composed of multiple records, fields, record attributes, field attributes, and data content. The records and fields in each two-dimensional table are stored...

Embodiment 2

[0080] This embodiment provides a two-dimensional dynamic contact query list query system based on a double hash structure, and the two-dimensional dynamic contact query list query system based on a double hash structure is included in a mobile terminal. see Figure 4 , showing the principle structure of a two-dimensional dynamic contact query list query system based on a double hash structure, including: a list generation module 1, a storage module 2, an operation module 3, a monitoring module 4, a first query module 5, and a second query module 6.

[0081] The list generating module 1 is configured to construct a contact query hash list; the contact query hash list includes a contact query duplicate name hash list and a contact query non-duplicate name hash list. The storage module 2 connected with the list generation module 1 is used for storing the constructed contact query hash list in the buffer pool of the mobile terminal. The computing module 3 connected to the stora...

Abstract

The invention provides a two-dimensional dynamic contact inquiry list inquiring method and system based on a double-hash structure. The method includes that a contact inquiry hash list is built; the contact inquiry hash list comprises a contact inquiry non-name-duplication list and a name-duplication hash list; whether a name list has duplicate names is judged, and on no judgment, the non-name-duplication hash list is inquired; on yes judgment, the name-duplication hash list is inquired; data content of a required two-dimensional table is inquired in the non-name-duplication hash list, line marks and row marks of a two-dimensional array are determined according to fields of the required two-dimensional table and recorded names, and the data content is inquired according to the line marks and the row marks; data content of the required two-dimensional table is inquired in the name-duplication hash list, a new contact inquiry non-name-duplication hash list is generated by using indexes, line marks and row marks of the two-dimensional array are determined according to the fields of the required two-dimensional table and the recorded names, and the data content is inquired according to the line marks and the row marks. By means of the method and system, contact inquiry access efficiency is improved, and inquiry is quickened by using the line marks and the row marks of the hash location two-dimensional array.

Description

technical field [0001] The invention belongs to the field of mobile communication, and relates to a dynamic contact query list query method and system, in particular to a double-hash structure-based two-dimensional dynamic contact query list query method and system. Background technique [0002] The phone book is the basic function of mobile communication devices such as mobile phones. This function is frequently used by users every day. It functions as a database for storing contact information. The query of target contacts is the basis of the database management system. Data, and provide functions such as interfaces for accessing data. Currently mainstream relational database commercial products such as oracle support this function. However, due to the limited time and space resources of the mobile phone system, it is impossible to deploy large-scale business database systems that consume a lot of resources and space, such as sybase and oracle, on mobile devices. However...
