Description

Service processing method, device and wireless communication terminal

The present invention relates to the field of communications, and in particular, to a service processing method, apparatus, and wireless communication terminal.

Background technique

A single-card dual-standby terminal means that one UE can camp in two modes at the same time. A typical example is that the CS side resides at 2G and the PS side resides at LTE/3G.

The single-card dual-standby terminal can perform PS services in the LTE system (supplemented by TD-SCDMA) through two communication subsystems, and perform CS services in the 2G system. Since the two communication subsystems (LTE/3G system and 2G system) of the single-card dual-standby multi-mode terminal are in working state when the CS service and the PS service are concurrent, the radios of the two communication subsystems simultaneously send and receive wireless signals. Therefore, there is mutual interference, that is, one mode of the transmitter will have an influence on the receiver sensitivity of the other mode. The mutual interference level of a single-card dual-standby multimode terminal is closely related to the transmit power and the two frequency bands at the same time. The greater the transmission power, the shorter the distance between the two antennas, and the smaller the band spacing (such as the 1880-1920 MHz band of LTE/3G and the 1805-1880 MHz band of 2G), the greater the mutual interference. The related art reduces interference by using a filter in the transmission and reception directions of the radio frequency, but even so, the PS side uplink transmission forms strong co-channel interference to the CS side downlink reception.

Preferred embodiment of the invention

Embodiments of the present invention will be described in detail below with reference to the accompanying drawings. It should be noted that, in the case of no conflict, the features in the embodiments and the embodiments in the present application may be arbitrarily combined with each other.

The present invention provides a method, a device, and a wireless communication terminal, which are applied to a wireless communication service, in the case of the existing wireless communication terminal. The wireless communication terminal is capable of processing the first type of service based on the first communication system and processing the second type of service based on the second communication system. As shown in FIG. 1, the service processing method includes:

Step 11: Before the selected frequency band processes the second type of service, determining whether the wireless communication terminal currently processes the first type of service, and generating a determination result;

Step 12: If the determination result indicates that the wireless communication terminal is processing the first type of service, acquiring the resident frequency band of the wireless communication terminal in the first communication system;

Step 13: In the frequency band of the second communication system searched by the wireless communication terminal, only the frequency band that does not overlap with the resident frequency band is selected to process the second type of service. When the service processing method of the embodiment of the present invention is to process the second type of service, it is first determined whether the wireless communication terminal is processing the first type of service, and if so, determining that the wireless communication terminal is resident in the first communication system. In the frequency band, and in the frequency band of the captured second communication system, a frequency band that does not overlap with the resident frequency band is selected to process the second type of service, thereby avoiding the same-frequency interference phenomenon generated by the two types of services during execution. . In addition, the wireless communication terminal selects the frequency band in the first communication system in which it resides to process the first type of service. Since there is no guarantee that the wireless communication terminal will not initiate the first type of service during the execution of the second type of service. Therefore, even if the wireless communication terminal does not process the first type of service, the frequency band selected for any second communication system will not generate the same frequency interference, but it should also avoid wireless communication when selecting the frequency band of the second communication standard. The terminals overlap in the resident frequency band of the first communication system. To this end, the service processing method of the embodiment of the present invention further includes:

Step 14, if the determination result indicates that the wireless communication terminal does not currently process the first type of service, acquiring the resident frequency band of the wireless communication terminal in the first communication system;

Step 15: The frequency band of the second communication system that is searched by the wireless communication terminal preferentially selects a frequency band that does not overlap with the resident frequency band to process the second type of service.

Preferably, in the foregoing embodiment of the present invention, the wireless communication terminal maintains a first list and a second list, where the first list is a list of current wireless communication terminals that capture a frequency band of the second communication standard. The real-time recording has all the frequency bands of the second communication system searched by the wireless communication terminal and the level values corresponding to the frequency bands, and the frequency bands in the first list are sorted according to their corresponding level values; the existing wireless communication terminal In all frequency bands of a communication system, the band processing service with the highest level value (ie, the best signal) is selected. Preferably, after acquiring the resident frequency band, the method further includes:

In the above step 13, the second type of service is processed from the first list by selecting a frequency band having the largest level value and the second list is not sorted. In addition, step 15 on the basis of the foregoing embodiment specifically includes:

Step 151: Find all frequency bands that are the same as the second list in the first list, and reduce the corresponding level value;

Step 152: Sort the frequency bands in the first list according to the size of the level value. Step 153: Select a frequency band with the highest level value from the first list to process the second type of service according to the sorting. In steps 151 to 153, the priority value of each frequency band in the first type table is changed by modifying the level value corresponding to the frequency band overlapping the resident frequency band in the first type table, thereby affecting the communication terminal. The frequency band for selecting the second communication system.

In addition, the higher the level value of the resident frequency band of the first communication system of the wireless communication terminal, the better the network ring of the first communication system is, and the smaller the influence of the same frequency interference of the second communication system is; The lower the level value of the resident frequency band of the first communication system of the wireless communication terminal, the greater the influence of the same frequency interference of the second communication system. To this end, in step 151, the power of the resident frequency band is obtained. A flat value; and a level variable value is determined according to a level value of the wireless communication terminal in the resident frequency band of the first communication system. All frequency bands identical to the second list are determined in the first list, and their corresponding level values are reduced according to the level variable value, thereby affecting the ordering in the frequency bands in the first list. Specifically, the larger the level value of the resident frequency band is, the smaller the corresponding level variable value is, and the smaller the frequency band of the second communication system overlapping the resident frequency band is in the order of the first list. Conversely, the smaller the level value of the resident frequency band, the larger the corresponding level variable value, and the greater the order change of the frequency band of the second communication system overlapping the resident frequency band on the first list.

The business processing method of the present invention will be described in detail below in conjunction with a practical application.

Illustratively, the wireless communication terminal may be a single-card dual-standby mobile phone (UE), which handles circuit-switched CS services (such as voice services) in a 2G communication system, and performs packet-switched PS services (such as data services in a 4G communication system). ). 2G corresponds to the first communication system of this document, and 4G corresponds to the second communication system of this document.

As shown in Figure 2, when the UE needs to initiate the PS service, the UE performs the following steps:

5201. Determine whether the UE's CS domain successfully resides on the 2G network.

5202, if the CS domain does not successfully reside, continue to find the network;

5203. If the CS domain has successfully camped, determine whether the UE is in the CS service.

5204. If the UE does not perform the CS service, clear the same-frequency list List_B corresponding to the PS side (that is, the second list in the embodiment of the present invention);

5205. If the UE does not perform the CS service, the CS domain resides in the 2G network with the reserved frequency band A, and all the 4G frequency bands that coincide with the frequency band A are recorded as the same frequency band B, and are stored in the same frequency list. List— B;

5206. If the UE does not perform the CS service, determine whether the UE needs to initiate the PS service.

5207. If the UE does not perform the CS service and does not need to initiate the PS service, the PS domain of the UE continues to camp in the original 4G frequency band.

S208. If the UE does not perform the CS service, and needs to initiate the PS service, find the same frequency band B in the first list that is the same as the same frequency list List_B, and subtract the level value from the level value Thd, and then Sorting according to the level value from large to small, and sequentially trying to access the 4G network from the frequency bands in the first list, and processing the PS service after successful access;

S209, if the UE is in the CS service, clear the same frequency list List_B;

S210, if the UE is performing the CS service, determining that the working frequency band of the CS service is A (that is, the 2G frequency band currently camped in the CS domain), and all the 4G frequency bands that coincide with the frequency band A are recorded as the same frequency band B, and the same frequency band is used. B is stored in the same frequency list List_B;

5211. If the UE is in the CS service, determine whether the UE needs to initiate the PS service.

5212. If the UE is in the CS service and does not need to initiate the PS service, the PS domain of the UE continues to camp in the original 4G frequency band.

5213. If the UE is in the CS service and needs to initiate the PS service, the UE is prohibited from accessing the 4G network in the same frequency band B in the same frequency list List B.

In addition, in order to prevent the UE from reselecting/switching the camping frequency band of the 2G network in the process of performing the CS service, the co-frequency list List_B is invalid, thereby interfering with the frequency band that the subsequent UE selects to access the 4G network. To this end, the service processing method of the present invention can also update the intra-frequency list List_B in real time. Specifically, the steps shown in Figure 3 are included:

5301, confirming that the UE is in the CS service;

5302, determining whether the CS domain has been switched; yes, executing S303; otherwise, re-executing S301;

5303, if the CS domain is switched, clear the same frequency list List_B;

S304, it is recorded that the newly camped 2G frequency band of the UE's CS domain is A', and all the bands 重' coincide

The 4G frequency band is recorded as the same frequency band Β' and stored in the same frequency list List_Β.
