1. A method performed by a radio network access point configured to provide access to a first network that provides voice services, comprising:
receiving a hand-off request at the radio network access point, the hand-off request being for user equipment connected to a second network that provides data services, the second network being different from the first network; replying to the hand-off request with channel assignment information, the channel assignment information comprising a first code corresponding to a first communication channel over which the radio network access point is configured to communicate, the first code, and thus the first communication channel, being reserved by multiple radio network access points within a same macro cell, the first code comprising a common Walsh code that is reserved for enhanced circuit switched fallback service (eCSFB) on the multiple radio network access points; receiving a message from the user equipment indicating that the user equipment has a connection to the radio network access point using the first communication channel; and redirecting the user equipment to a second code, and thus a second communication channel, to maintain the connection without the first communication channel so that the first communication channel can be freed, the second code being a Walsh code that is different from the common Walsh code, the second communication channel being different from the first communication channel. |
