Source-side and target-side handover communication devices, a communication system and call handover method are provided, wherein the source-side handover communication device determines the type of a call which a user equipment currently needs to hand over, and when determining that the type of the call is a preset type, the source-side handover communication device configures identification information indicating the type of the call in a handover request message, and then sends the handover request message to a target-side handover communication device; the target-side handover communication device obtains the type of the call which the user equipment currently needs to hand over according to the request message, and then selects a corresponding handover strategy according to the obtained type, so as to avoid the occurrence of the case in which the handover is wrongly rejected because the type of the call cannot be effectively identified, thereby improving the handover success rate. |
