Problems solved by technology

[0004] However, for the first solution, the splitting of the antenna leads to a decrease in the receiving performance. In a weak or poor signal environment, the data reception of the two cards is affected; for the second solution, the card 2 in the idle state receives data The duration is short, resulting in low utilization of the RF channel allocated to the card 2

Embodiment 1

[0052] figure 2 It is a schematic diagram of the signaling flow of Embodiment 1 of the multi-card concurrent receiving method provided in this application. see figure 2 As shown, the multi-card concurrent receiving method provided in this embodiment includes:

[0053] S201. The card 2 sends an event-type resource allocation request to the resource allocation module.

[0054] In a possible implementation manner, when the card 2 determines that event-type resources are needed, it sends an event-type resource allocation request to the resource allocation module. When the card 2 in the idle state has data to receive, it indicates that event-type resources are needed, and at this time, an event-type resource allocation request can be sent to the resource allocation module. The card 2 in the idle state can determine that there is data to receive in the following situations: power-on to search for a network, search for a cell, receive network system information, receive network ...

Embodiment 2

[0080] Figure 10 It is a schematic diagram of the signaling flow of Embodiment 2 of the multi-card concurrent receiving method provided in this application. This embodiment introduces a combined receiving solution when the total number of resource channels currently required is less than or equal to the number of resource channels supported by the terminal device. see Figure 10 As shown, the multi-card concurrent receiving method provided in this embodiment includes:

[0081] S1001. The card 2 sends an event-type resource allocation request to the resource allocation module.

[0082] S1002. The resource allocation module determines the total number of resource channels currently required by card 1 and card 2 according to the event-type resource allocation request and the number of resource channels currently used by card 1 .

[0083] Further, after the resource allocation module determines the total number of resource channels currently needed, it compares the total numbe...

Abstract

The present application provides a multi-card combined receiving method and device. The method includes: if the total number of resource channels currently required is greater than the number of resource channels supported by the terminal device, then determine from the resource channels currently used by the first mobile phone card Target resource channel; sending a first message to the first mobile phone card, the first message is used to indicate that the target resource channel is occupied by the second mobile phone card, and is also used to indicate that the first mobile phone card uses a terminal Among the resource channels supported by the device, resource channels other than the target resource channel receive corresponding semi-static SPR data; send a second message to the second mobile phone card, and the second message is used to indicate that the second The mobile phone card uses the target resource channel to receive corresponding event-type data. Compared with the prior art, the resource utilization rate is improved, and the reception performance is guaranteed at the same time.

Description

technical field [0001] The present application relates to the communication field, and in particular to a method and device for multi-card reception. Background technique [0002] A multi-card terminal refers to a terminal that supports the insertion of multiple mobile phone cards at the same time. Currently the most common is the dual card terminal. The two mobile phone cards on the dual-card terminal may be in the connected state at the same time, may be in the idle state at the same time, or one may be in the connected state and the other in the idle state. [0003] For the scene where one is in the connected state and the other is in the idle state, in the prior art, the following two schemes are used to realize data reception. The first scheme is to split the antennas, and the two sets of antennas after splitting are respectively It is used to receive the data of two cards. The second solution is to split the shared RF channels. For example, the terminal has 5 shared...
