Abstract

A multi-card multi-communication mobile terminal. The multi-card multi-pass mobile terminal includes: a radio frequency processing unit, corresponding to a single carrier signal, suitable for processing data of multiple user cards in parallel; a baseband processing unit, coupled with the radio frequency processing unit, suitable for parallel processing of multiple user cards The data of the uplink channel and downlink channel of the card, the baseband processing unit includes: a shared processing unit and a plurality of independent processing units, wherein the first port of the shared processing unit is coupled to the radio frequency processing unit, and the second port Coupled with the plurality of processing units, corresponding to a single carrier signal, and suitable for processing data of multiple user cards in parallel; the plurality of independent processing units correspond to multiple user cards, and are suitable for processing data of each user card separately. Applying the above mobile terminal can not only reduce chip cost and power consumption, but also support large data packet services without loss.

Description

technical field

[0001] The invention relates to the communication field, in particular to a multi-card and multi-communication mobile terminal. Background technique

[0002] With the popularization of mobile terminals, more and more operators have put forward the requirement of dual-card dual-pass. Among the existing products, the high-performance dual-card dual-pass chip adopts two radio frequency and baseband processing units corresponding to a single carrier, resulting in high chip area, cost and power consumption, so cost-sensitive customers will not Refuse to support the dual-card dual-pass function; the low-cost dual-card dual-pass chip has limited processing capacity, and can only support services with a large tolerance to packet loss, small data packets, and regular data transmission cycles, and cannot support services with large data packets without loss . Contents of the invention

[0003] The technical problem solved by the invention is how to realize a multi-...

Embodiment Construction

[0024] Among the existing products, high-performance multi-card multi-pass chips use radio frequency and baseband processing units corresponding to multi-carriers, resulting in high chip area, cost and power consumption, so cost-sensitive customers will refuse to support them due to high costs Multi-card and multi-pass function; the low-cost multi-card and multi-pass chip has limited processing capacity and poor performance, and cannot support the business of large data packets without loss.

[0025] In view of the above problems, the embodiment of the present invention provides a multi-card multi-pass mobile terminal for multiple user cards of the same operator, including: a radio frequency processing unit, a shared processing unit and a plurality of independent processing units, the radio frequency processing unit The unit and the shared processing unit correspond to single-carrier signals, are suitable for parallel processing of data of multiple user cards, and can effective...
