Description
Technical Field
The invention relates to the technical field of terminal network search, in particular to a method and a device for searching a high-speed network in a high-speed network edge cell.
Background
LTE (Long Term Evolution), also known colloquially as 3.9G, has a downlink peak rate of 100 Mbits/s and an uplink peak rate of 50 Mbits/s. LTE is a transition technology between 3G and 4G, is a global standard of 3.9G, adopts OFDM (Orthogonal Frequency Division Multiplexing) and MIMO (Multiple-Input Multiple-Output) as unique standards for wireless network evolution, improves and enhances the 3G air Access technology, and improves the performance of cell edge users, increases cell capacity, and reduces system delay by using a technology with OFDM/FDMA (Frequency Division Multiple Access) as a core.
Operators in most countries of the world currently, including three major operators in China (mobile, Unicom, telecom), have built or are building LTE networks. In the face of huge business opportunities about to be brought by LTE, all large manufacturers take the initiative to seize the market. In addition to the market share of each operator, each terminal manufacturer also successively releases or develops terminal devices supporting LTE systems.
Although LTE technology has been proposed in 2004, it is applied to business, as well as in recent years. Therefore, the LTE is still in the initial stage, even in developed countries in europe and america, the LTE network coverage is not complete, and the LTE network of our national operator is only built in part of several large cities at present. That is, the LTE network cannot cover all regions at one time, and the building of the LTE network is a process of gradual and gradual expansion.
Therefore, at the initial stage of network construction, it is inevitable to have places which cannot be covered by the LTE network, and thus, edge zones of LTE coverage are formed, and compared with areas with stable LTE coverage and areas without LTE coverage, LTE services in these areas are not stable and sometimes not.
In the search priority of the Mobile phone, LTE has a higher priority than GSM (Global System for Mobile communication)/WCDMA (Wideband Code Division Multiple Access), so when the Mobile phone registers to GSM/WCDMA, the Mobile phone will periodically search for an LTE network according to a certain rule. According to the existing patent technology, when the mobile phone is in an area with LTE coverage, the mobile phone searches an LTE network at short intervals, and when the mobile phone is in an area without LTE coverage, the mobile phone searches the LTE network at long intervals, so that the purposes of optimizing LTE search time and reducing power consumption are achieved. However, for the LTE coverage edge zone, that is, the LTE coverage edge zone has a cross zone with the conventional 2G/3G network, that is, in a cell coverage area of the conventional 2G/3G network, a part of the cell can search for the LTE network, another part of the cell cannot search for the LTE network, and some areas sometimes have LTE coverage and sometimes do not have LTE coverage. For the cells in the LTE coverage edge zone, the prior art adopts a suitable LTE optimized search strategy without aiming at the particularity of the cells, so that the optimal LTE search time interval cannot be selected, which results in a longer LTE search or an increased power consumption.

The method is characterized by comprising the following steps:
the LTE full coverage module 401 is a 2G/3G cell list, and a series of 2G/3G cell id lists are stored in the list, indicating that stable LTE service can be obtained when a cell phone registers a cell with these id lists.
The LTE non-coverage module 402 is a 2G/3G cell list, and a series of 2G/3G cell id lists are stored in the list, indicating that LTE service cannot be obtained when a cell phone registers with the cell id list.
The LTE edge cell module 403 is a 2G/3G cell list, in which a series of 2G/3G cell id lists are stored, and a counter for identifying the number of times that an LTE network is successfully searched. When a cell in the list is registered by the handset, it means that in this cell, there are some areas with LTE coverage and some areas without LTE coverage. And if the value of the counter reaches a threshold value, the cell is subjected to network optimization and has reached the requirement of complete coverage, and the cell is transferred from the LTE edge cell module to the LTE complete coverage module.
The cell id obtaining module 404 is configured to obtain a cell id of a 2G/3G network currently registered in the mobile phone, compare the cell id with an id stored in an LTE campeable module/LTE non-campeable module list, determine in which list the id is stored, and send a comparison result to the BSR-Timer selection module.
The LTE edge cell determining module 405 is configured to determine whether the current cell is an LTE edge cell. When the cell id obtaining module 404 obtains the cell id currently registered, the LTE full coverage module 401 is searched, and if the cell id exists and the LTE network entity finds that the LTE network cannot be registered in the cell, the 2G/3G cell storage module 406 is notified, and the cell id is transferred from the LTE full coverage module 401 to the LTE edge cell module 403.
The 2G/3G cell storage module 406 receives the cell id transmitted by the LTE edge cell determining module 405, and stores the cell id in the variable BSR-Timer storage module 407.
The variable BSR-Timer storage module 407 stores a series of increasing BSR-Timer values, and selects the BSR-Timer values sequentially increasing when a smaller BSR value cannot search the LTE network, thereby achieving the purpose of saving power consumption.
The BSR-Timer reading module 408 reads a series of BSR-Timer values stored in the variable BSR-Timer storage module 407, and uses the read series of BSR-Timer values as the LTE search time interval. When the cell id registered by the mobile phone belongs to the LTE edge cell module, the LTE network is sequentially searched by using the time interval stored in the variable BSR-Timer reading module 408, as shown in fig. 9, the sequence is sequentially increased in increments, taking minutes as a unit, until a time value is increased to a constant value. When the sequence is used for registering a mobile phone in a 2G/3G cell in an LTE coverage edge zone, the LTE network is searched in an ascending order in turn by adopting values defined by the sequence.
The LTE search module 409 initiates a search of an LTE network at regular time according to a time interval specified by a BSR-Timer, based on whether a cell registered by a current mobile phone includes an LTE campeable module/an LTE non-campeable module.
Fig. 5 shows a diagram of an LTE full coverage module provided in an embodiment of the present invention, and as shown in fig. 5, the LTE full coverage module is composed of a series of 2G/3G cell ids. The LTE full coverage module indicates that when the handset registers with one of these cells, there is an LTE network available in these cells and therefore the search should be done at normal LTE search intervals. When the 2G/3G cell id corresponds to the 2G/3G network of the cell A registered by the mobile phone in fig. 3, a normal LTE network can be obtained.
Fig. 6 shows a diagram of an LTE coverage-less module according to an embodiment of the present invention, and as shown in fig. 6, the LTE coverage-less module is composed of a series of 2G/3G cell ids. The LTE no-coverage module means that when the handset is last registered in these cells, no LTE network is searched in these cells, and thus the LTE network should be searched using a long time interval. When the 2G/3G cell id corresponds to the 2G/3G network of the cell B registered by the mobile phone in fig. 3, in the coverage area of the 2G/3G, part of the area can obtain the LTE network, and part of the area cannot obtain the LTE network.
Fig. 7 shows a structure diagram of an LTE edge cell module according to an embodiment of the present invention, and as shown in fig. 7, the LTE edge cell module is composed of a series of 2G/3G cell ids. The LTE edge cell module is that the cell and LTE cover a cross area, i.e. part of the area has LTE coverage and part of the area has no LTE coverage, in these cells, the LTE network should be searched using an increasing time interval. The 2G/3G cell id corresponds to the 2G/3G network in fig. 3, where the cell C cannot be acquired when the mobile phone registers in the 2G/3G network.
Fig. 8 shows a flowchart of an optimized LTE edge cell search method provided by the embodiment of the present invention, and as shown in fig. 8, the steps are as follows:
step 1: when the mobile phone is in the LTE normal registration state, interaction among all modules is not carried out.
Step 2: when the mobile phone registers in the 2G/3G network, the cell id acquisition module acquires the cell id of the current 2G/3G network and sends the id to the LTE edge cell judgment module.
And step 3: the LTE edge cell distinguishing module reads a cell id value stored by the LTE edge cell module, and if the current 2G/3G cell id is already stored in the LTE edge cell module, the id is transmitted to the BSR reading module.
And 4, step 4: the BSR reading module stores a series of BSR-Timer values from the variable BSR-Timer storage module and transmits the BSR-Timer values to the LTE searching module.
And 5: the LTE search module searches for the LTE network in an order of increasing time intervals according to the increasing BSR-Timer values.
Step 6: and if the LTE network is searched, adding 1 to a counter value of the successful search LTE corresponding to the cell id, and if the counter value reaches a threshold value, transferring the cell id to an LTE complete coverage module.
And 7: in step 3, if the LTE edge cell determining module determines that the current 2G/3G cell id is not in the LTE edge cell module, the LTE full coverage module is read, and if the id exists in the LTE full coverage module, the LTE search module is notified to search the LTE network according to a normal fixed time interval.
And 8: if the LTE network can not be searched in the current search of the cell completely covered by the LTE, the cell is judged to be in the LTE coverage edge zone, the cell id is transferred to an LTE edge cell module, and meanwhile, the variable BSR-Timer value stored in the variable BSR-Timer storage module is read, and the LTE network is searched in the time interval increasing sequence.
And step 9: in step 7, if the LTE edge cell determining module determines that the current cell is not in the LTE full coverage module, the LTE no-coverage module is read, and if the id exists in the LTE no-coverage module, the LTE search module is notified to search for the LTE network according to the long time interval. If the LTE network is searched, which means that the LTE network is not searched last time, but the LTE network is searched this time, the cell is judged to be in an LTE coverage edge area, and then the cell id is transferred to an LTE edge cell module.
In summary, the present invention has the following technical effects:
the invention provides a 2G/3G cell list in the terminal, the list stores the cell id of the LTE coverage edge zone, when the terminal registers the cells of the LTE coverage edge zone, the invention adopts the mode of gradually increasing and searching the LTE time interval, thereby achieving the purposes of optimizing the LTE network residence speed and reducing the power consumption.
