Description
Technical Field
The present invention relates to a cross-system handover technology, and in particular, to a blind handover method, system, and network side.
Background
Mobile communication systems can meet the requirement of people to communicate anytime and anywhere, and currently, the mobile communication systems are gradually moving from second Generation mobile communication technology (2G, 2nd Generation) network systems to third Generation mobile communication technology (3G, 3rd Generation) network systems. Among them, the 3G network system is represented by a Time Division-Synchronous Code Division multiple access (TD-SCDMA) system and a Wideband Code Division Multiple Access (WCDMA) system. Because the network construction is a progressive process, the emerging 3G network system needs to coexist with the existing 2G network system in the transition period from 2G to 3G, so that the full coverage of the 3G network system is completed in stages as required on the basis of the existing 2G network system, and the gradual popularization of the 3G network system is realized.
In a mobile communication system, since a mobile terminal moves from the coverage area of one cell to the coverage area of another cell, in order to ensure the continuity of the mobile terminal call, the wireless connection between the mobile terminal and the network side needs to be handed over from the original cell to the new cell, which is a handover procedure in the mobile communication system. For the mobile communication system with 2G and 3G coexisting, cross-system switching must be used in the border area between the 3G network system and the 2G network system to ensure the continuous coverage of signals; and the mobile terminal needs to be switched to the 2G network system in the non-edge area covered by the 3G network system due to load.
According to the third Generation Partnership Project (3 GPP), the mobile terminals performing the inter-system handover need to have a measurement capability of the inter-system cell signal quality, and herein, the mobile terminals having the inter-system measurement capability are referred to as first type terminals. In practical applications, in order to quickly capture the market, 3G operators develop mobile terminals applied to 3G network systems that do not have the capability of measuring the signal quality of cells in different systems, but only have the capability of switching between different systems, and can perform switching between different systems. Here, a mobile terminal having only the inter-system handover capability but not the inter-system cell signal quality measurement capability is referred to as a second type terminal, and the inter-system handover performed by the second type terminal is referred to as blind handover.
In the prior art, the method for realizing the blind handover of the different systems of the second-class terminal has lower handover success rate and accuracy because the handover is directly performed without measuring the signal quality of a target system and whether handover is successful or not is not guaranteed.

Detailed Description
The technical solution of the present invention is further elaborated below with reference to the drawings and the specific embodiments.
The invention provides a blind switching method, which utilizes the inter-system cell signal quality measurement capability of a first class terminal in a mobile communication system and combines the positioning function of a network side to obtain the corresponding relation between position information and inter-system signal coverage information, thereby being capable of utilizing the corresponding relation to guide the inter-system blind switching of a second class terminal.
The flowchart for acquiring the corresponding relationship between the position information and the inter-system signal coverage information in the present invention, as shown in fig. 1, mainly includes the following steps:
The network side distinguishes a first class terminal and a second class terminal by obtaining the signal quality measurement capability of each terminal in the mobile communication system, wherein the terminal with the signal quality measurement capability is the first class terminal, and the terminal without the signal quality measurement capability is the second class terminal. The network side sends a signal measurement command to a first class terminal in the mobile communication system, and the first class terminal is required to measure the signal quality.
The first kind of terminal receives the signal measurement order of the network side, and carries on the measurement of the signal quality, the signal coverage information of different system is formed by the different system cell measured, the first kind of terminal reports the measurement result carrying the signal coverage information of different system to the network side.
And 103, the network side acquires the current position information of the first-class terminal and combines the current position information with the corresponding inter-system signal coverage information.
The network side has the capability of measuring the position of the terminal, and can acquire the current position information of the first type terminal through an actual positioning method according to the measurement result reported by the first type terminal. The positioning method in practical application comprises the following steps: a Positioning method based on a Global Positioning System (GPS), a Positioning method based on an Observed Time Difference Of Arrival (OTDOA), a Positioning method based on a field strength, and a Positioning method based on an Enhanced-Observed Time Difference (E-OTD), and the like. In addition, the operation of measuring the current position of the first-class terminal can also be completed by the first-class terminal, and the positioning method can be realized in the first-class terminal, and in such a case, the first-class terminal needs to report the measured position information and the measurement result of the signal quality to the network side. Of course, both the first type terminal and the network side may have the function of location measurement.
And combining the current position information of the first-class terminal and the different-system signal coverage information in the measurement result by the network side, thereby obtaining the corresponding relation between the position information and the different-system signal coverage information. It should be noted that, if the mobile communication system is a Hierarchical Cell Structure (HCS) networking method, there may be a situation where one location area has coverage of cells of multiple different systems, and therefore, for the mobile communication system adopting the HCS networking method, the corresponding relationship between the location information and the coverage information of signals of different systems may be a one-to-many corresponding relationship, that is, the coverage information of signals of different systems corresponding to the location information includes multiple cells of different systems.
The method for acquiring the corresponding relationship between the location information and the inter-system signal coverage information is further described in detail in the following with specific embodiments. The first type of terminal in this embodiment is a terminal in 2G, and may perform signal measurement of a 2G cell, as shown in fig. 2, fig. 2 is a schematic diagram of location area division according to an embodiment of the present invention, and in this embodiment, a network side needs to obtain 2G signal coverage information on each location area within a range shown by a dotted line in fig. 2. The network side commands the first type of terminal to measure the signal quality, and the areas surrounded by different hexagonal solid lines in fig. 2 represent the position areas of different first type of terminals measured by the position measurement function; the different areas of the regions surrounded by the hexagons represent different measurement accuracies which can be achieved by the position measurement function, and the regions surrounded by the hexagons are large and represent lower accuracy of position measurement; the area enclosed by the hexagon is small, and the accuracy of the measurement of the identification position is higher. When the number of first-class terminals performing signal quality measurement is increasing, the 2G signal coverage information of each area within the range shown by the dotted line is gradually measured, but in practical application, there is a case where the 2G signal coverage information of some location areas is not measured, and for a location area that is not measured, an estimated value corresponding to the location area may be set until the 2G signal coverage information corresponding to the location area is acquired, and then the estimated value is replaced with the 2G signal coverage information. The estimated value can be calculated by adopting an interpolation function.
By the method, the network side can acquire each piece of position information and corresponding 2G cell coverage information within the range of the dotted line. A database is established on the network side, and the database stores the location information and the corresponding 2G cell coverage information in a table form, as shown in table 1 below, the information that can be acquired from table 1 includes: the method comprises the steps of determining a geographic position, whether the corresponding geographic position has the coverage of the different system cell, whether the coverage information of the different system cell is a measured value or an estimated value, and the coverage information of the different system cell.
| Geographic location indexing | Geographic location | Whether there is cell coverage of different system | Measured/estimated value | Inter-system cell coverage information |
| ...... |
TABLE 1
It should be noted that, in order to maintain the validity of the inter-system cell coverage information corresponding to each location information in the database in terms of time, the signal quality in the location area may be re-measured at regular or irregular time, so as to achieve the purpose of continuous update. In the invention, a threshold value of signal quality can be preset on a network side, and the different system cell with the signal quality higher than the preset threshold value is added into the coverage information of the different system cell, so that the second type of terminal can be prevented from being switched to the different system cell with poor signal quality.
As shown in fig. 3, the flowchart for performing inter-system blind handover on a second type of terminal mainly includes the following steps:
And when the network side needs to perform blind switching on the second type terminal, the position information of the second type terminal is obtained through the position measurement function.
And the network side obtains the signal coverage information of the different systems, informs the second type of terminal to switch, and switches the wireless connection of the second type of terminal to the different system cell in the signal coverage information of the different systems. It should be noted that, if there are a plurality of different system cells in the different system signal coverage information, one different system cell may be selected from the plurality of different system cells according to a scheduling principle in practical application for blind handover, where the scheduling principle includes: random scheduling, priority scheduling, and the like.
For example: the first type of terminal is a 2G terminal and has the measurement capability of 2G signal quality, and the terminal A in the 3G terminal is a second type of terminal and does not have the measurement capability of signal quality; in practical application, when the terminal a needs to be switched from the 3G cell to the 2G cell, the network side acquires the current location information of the terminal a through location measurement operation, searches for a corresponding relationship between the location information and the 2G signal coverage information, acquires the 2G signal coverage information corresponding to the current location information of the terminal a, and switches the wireless connection of the terminal a to the 2G cell in the 2G signal coverage information.

And a switching unit 23, connected to the signal coverage information obtaining unit 22, configured to switch the wireless connection of the second type terminal 30 to the inter-system cell in the inter-system signal coverage information according to the inter-system signal coverage information.
